Bird Soul: Unparalleled National Warriors at the Beginning.

Chapter 713 Extra Chapter 1: Nan Mengke's Story - The Tribulation of Immortality
When did you notice the change in your brother?

This is the question Nan Mengke has been asking himself all this time.

From childhood, she always regarded her older brother, Nan Mengyan, as her role model.

Although she was born into a wealthy family, her irresponsible parents traveled all over the world and, apart from sending money to their children like ATMs, never cared about her grades, studies, or life.

Therefore, in Nan Mengke's life, her brother occupied the vast majority of her time.

Perhaps because she enjoyed reading pure love novels like "Romeo and Juliet" and "The Butterfly Lovers" since childhood, she developed a longing for beautiful and pure love.

Because of this, some of her feelings overlapped and became a secret in the young girl's heart.

She soon learned that certain emotions in this world were actually considered taboo by society, and in the end, the girl could only bury those forbidden feelings deep within her heart.

With her parents traveling far away and few friends, she didn't know who to confide in.

Ultimately, this sentiment can only be transformed into self-improvement.

If she becomes good enough, perhaps her brother will notice her more.

The girl's wish was so simple and unpretentious.

She never imagined that a game of mahjong in her youth would lead Nan Mengyan down a path of complete depravity, and everything would change afterward.

Whether it's grades, personality, or life, her brother has become increasingly insecure and sensitive, and has grown increasingly estranged from his sister.

The girl was heartbroken to see her brother like this, but she found there was nothing she could do.

Even when she tried to comfort and care for him, the boy remained indifferent and unresponsive. She could only watch helplessly as he gradually descended into depravity.

In the end, Nan Mengke, whose love turned to hatred, could only turn his pain into verbal disdain for his brother, hoping to make Nan Yan reflect on his actions in this way.

But her brother went down a path he didn't know and never returned, and they gradually drifted apart.

As the younger sister, she didn't know how to win her brother back. She could only vent her frustration by working hard to improve herself, trying to show her brother a more perfect sister and let him know that she had grown to a level he had to look up to.

But the more they did this, the further apart they became, until they were almost from two different worlds.

But I don't know when it started.

The girl suddenly noticed that her brother had changed strangely.

The boy suddenly started calling her "my dear Yimoduo," suddenly started running to exercise, suddenly brought her breakfast, and suddenly asked her where the mahjong machine was at home. When she scraped her toe, he applied medicine to her foot in a forceful manner.

All these abrupt changes left the girl feeling somewhat lost and disoriented.

Although she was pleased with her brother's change, after so many years, she no longer knew how to get along with him and could only continue to maintain her previous arrogant attitude and show her disdain.

Afterwards, Minami showed unparalleled talent in the field of mahjong, and took this talent to school, to Nagano Prefecture, and to the national and even the world stage.

He even had an amazing talent in the field of Go, and taught her many strange joseki and how to break ancient joseki.

Ultimately, with the skills taught to her by her brother, she successfully won the national Go championship.

Meanwhile, Nanyan led the Kiyosumi Mahjong Club to a resounding victory, winning both the individual and team championships at the national tournament.

Nan Mengke watched her brother grow up silently, and couldn't help but smile. Although she didn't know why her brother had suddenly changed, it was for the better, so she was naturally very happy.

But slowly.

She realized that she and her brother seemed to be growing distant again.

My brother has made many new friends, some boys, and of course, many more girls.

Moreover, many of these girls are very cute, very gentle, and the perfect kind of girl to be a girlfriend.

Although the girl had a premonition of what might happen in the future, her brother was moving in a good direction after all. Even if she might lose her brother, the outcome would still be good.

Besides, these were all her brother's own choices, and she had no way to interfere.

If one of these girls were to be chosen as the most suitable to become her future sister-in-law, that wouldn't be unacceptable.

Think so.

Until that event happened.

I heard that my brother announced he's taking a year off from school to travel and plans to come home.

Nan Mengke returned home in high spirits, wanting to celebrate with Nan Yan's championship victory and share her joy at winning the national competition.

But when she returned home, Nan Yan wasn't there; instead, there was an uninvited guest—

New son admires!
"You, you, you, you! How dare you sleep in my house, and in my brother's room no less!"

Nan Mengke was furious!
She didn't dislike Shinko, that little bitch; in fact, the two were very good friends. But she just didn't like this little bitch getting close to her brother.

Her brother is so perfect, she absolutely cannot let this guy beat her.

Otherwise, if she ever calls her friend "sister-in-law" in the future, she'll explode!
"woooooo"

Xinzi was a little flustered because she didn't expect Nan Mengke to come home suddenly, but she was good at acting and quickly put on the image of an innocent girl who was forced into the sex industry, and became pitiful.

"Yan-gege took me home yesterday and then he violated me severely. He grabbed my pigtails and used them as reins to ride me. I couldn't resist and lost my virginity to him."

Nan Mengke's face immediately turned bright red. As an innocent young girl, she stammered when she heard such inappropriate content.

"What nonsense are you spouting? My brother would never do such a thing! Get up, Xinzi Chong! Where is my brother?"

"Brother Yan was too intense yesterday, I can't get up now."

Xin Zichong felt a surge of nervousness and hugged the blanket tightly.

However, she was clearly no match for Nan Mengke's strength and was thrown down.

Holding the blanket, Shinko got out of bed and looked at the clean white sheets with lingering fear, then breathed a sigh of relief.

Fortunately, Brother Nan Yan was meticulous and did not leave any evidence against him.

Now she was finally relieved and smiled at Nan Mengke: "Why don't you leave the blanket unwashed and give it to me? It still has the scent of me and my brother in it."

"Get out of here and wash yourself clean!"

Nan Mengke was furious.

Seeing the girl jumping up and down, Shinko calmly went to wash the sheets.

However, the moment she left, Nan Mengke's expression instantly turned cold.

Although Shinko Aoi disguised herself very well, and there were no traces of Shinko in her brother's room, Nanmu Ke knew very well that her brother had come back yesterday.

And more importantly, the room still smelled of my brother's sweat.

You know, Nan Mengyan is the kind of guy who completely gives up when he gets home. He doesn't want to do anything. He's not going to break a sweat at home.

So what he and Shinko Ake did in the room yesterday is self-evident.

Sure enough, boys like innocent, flirtatious "green tea" girls, whether they're from a wealthy family or a modest family. Men may say they like them, but their actions speak louder than words.

With so many girls to choose from, the brother chose a small beaker.

Nan Mengke felt genuinely that it was not worth it.

Her beloved brother clearly deserved better.

However, the deed is done, and if the two truly love each other, she, as their younger sister, will not try to break them up.

But later she realized just how outrageous her brother was!
A year later, Nan Yan returned from his school trip.

Nan Mengke noticed that there were more girls around her brother now.

There's Shirazuki Mu, who specially waited for him to come home in Nara Prefecture; Fukuro Mihoko, who is better than her at cooking and housework; the graceful and gentle shrine maiden Ishido Kasumi; and Yumeno Maho, the junior who likes to sit on Minamihiko's lap all the time.

Many beautiful and lovely girls took the initiative to throw themselves into his arms.

He even accepted all offers from his own brother.

Even more outrageous, once when they were having a mahjong party at home, a girl named Kana Ikeda suggested playing strip mahjong. In the end, all the girls' clothes were torn off, while Minamihiko's socks were undamaged and his clothes were only slightly dirty.

That's incredible! My brother is amazing!
No! wrong!

Nan Mengke, you're focusing on the wrong thing.

They should be severely criticized, how could these people be so chaotic!

To do such outrageous and immoral things in her own cozy little home with her brother is simply depraved, licentious, and indulging in sensual pleasures—it's utterly immoral!

She is clearly the only lady of this little house!

Now her home has become a den of debauchery and debauchery.

Her brother shouldn't be like this. He's already in a relationship with a girl, so he should be loyal to her. How could he do such a thing?

This is really too much!

Nan Mengke, a fan of pure love stories, was very disappointed.

So she confided some of her worries to Haramura, the perfect sister-in-law she had always admired, and Haramura, as always, gently comforted her.

"Feeling much better now, Xiao Ke?"

"Yes, thank you, Xiao He."

After Nan Mengke poured out her grievances, she did feel much better.

But considering Nanyan's recent dissolute behavior, and looking at Haramura Kazumi, who clearly had a strong liking for her brother, she couldn't help but ask, "Kazumi, haven't you and my brother made any progress?"

Upon hearing this, the girl blushed and said, "Um... Yan and I are already living together."

"..."

Nan Mengke's vision went black.

Her brother was living with Haramura while also having ambiguous relationships with various girls.

The brother she thought was holy, flawless, and godlike was actually a complete scumbag!

The girl's dreams were shattered completely.

At that moment, she straightened up. She refused to accept that her brother had become this kind of person, and she wanted to save her brother from the abyss of depravity.

Her brother should be perfect!
"where are you going?"

Seeing the extremely gloomy expression on Nan Mengke's face, Haramura Kazuki sensed that something was wrong.

"I'm going to find my brother and confront him!"

Nan Mengke was blinded by his resentment.

The brother in her heart should be the ideal male god, without any flaws. Moreover, love should be faithful and unwavering. How can one fall in love with one person after another?
She didn't want her brother to become a scumbag, letting her down, and also letting down Haramura and such a good girl.

She has to confront her brother face to face!
Back home, sure enough, I found the girls still playing mahjong with Minami. Ikeda Hana, Dojima Tsuki, and Kataoka Yuki had lost a total of 500,000 yen. Keep in mind that they were playing a low-stakes game with 1000 points for 100 yen and no horse points, yet they still lost so much.

"I've lost so much that I have no choice but to sell myself to Nan Yan. I'm so miserable!"

"How many Mexican kebabs could this money buy? Now I can only eat my senior's kebabs to pay off my debt, sob sob sob!"

"Cheer up! I, Dojima Tsuki, am not short of money. At worst, I can provide you with interest-free loans. We can still fight on!"

"That's enough of you!"

Someya Mako looked at the three unlucky guys with a speechless expression. These guys were just giving Nanyan money for nothing.

Someone needs to come and persuade them, otherwise these three will really lose so much they'll have to sell themselves.

At that moment, Nan Mengke walked up.

Watching Nan Yan having fun with the girls, she felt increasingly uncomfortable.

"elder brother"

"What's wrong? Want to play cards together?" Nan Yan seemed not to notice the girl's dark expression.

"I challenge you to a duel, using Go!" Nan Mengke stared at Nan Yan, her expression a mixture of grievance, pitifulness, helplessness, and a determination to save her brother.

She didn't want her brother to continue indulging in women.

So she decided to use her best methods to reform her brother!

"Huh?" Nan Yan was taken aback.

If it came down to a Go duel, he would definitely be no match for his sister now.

You should know that he had previously given his all, passing on all the dog-fighting techniques he knew to his sister, since she was his closest person, so Nan Yan held nothing back.

Furthermore, with the experience gained from the national Go tournament that year, the girl's overall strength was clearly far superior to his, and he simply couldn't beat his sister.

Now that Nan Mengke suddenly wants to duel him using Go, it's no different from him, who has entered the realm of demons and gods, fighting against an old man like Akagi, who is in the realm of dementia. It wouldn't be an exaggeration to say that he's bullying him.

"I don't care, you have to duel me, and the winner can make one demand that the loser can't refuse!"

Nan Mengke bit her lip; she had already decided on her demands after defeating Nan Yan.

That means her brother has to choose one of all the girls!
She would never allow her perfect brother to become a scumbag who builds a harem.

Whether it's Mihoko, Haramura Kazu, Shinko Aki, Ishido Kasumi, or Shirazuki Mu, and all the other girls, he can only spend the rest of his life with one of them.

Otherwise, she would no longer acknowledge Nan Yan as her brother!

The girls present seemed to have noticed something was off about the younger sister. In fact, they had sensed it to some extent before. This younger sister was somewhat out of place with them. Although she didn't reject the girls coming to visit, she seemed to dislike them.

Many girls can tell that this younger sister has a bit of a brother complex.

Perhaps they had been playing too much with Nan Yan these past few days, which made the younger sister unhappy.

Someya Mako couldn't help but glance at Ikeda Kana and Kataoka Yuki. It was all those two's fault for saying they wanted to play some kind of unconventional mahjong, and in the end they lost all the clothes on their bodies. My sister is a very traditional and good girl. Of course, it would make her uncomfortable if you played this kind of mahjong.

Now look what's happened, the brother and sister are going to have a fight.

“Yes, yes”

Faced with his sister's sudden outburst of willfulness, Nan Yan was slightly taken aback. He was indeed no match for his sister in Go, and he could sense that she was having a little tantrum. But if this could cheer her up, that would be good.

As for what she might ask for, Nan Yan didn't really think much about it.

After all, his sister would never harm him.

Then the chessboard was set up, and the two began to play, while the other girls watched from a distance.

The vast majority of girls don't know how to play Go, and some don't even have a beginner level. After all, unlike games like mahjong, which have simple and easy-to-understand basic rules, Go is much more difficult to learn.

However, there were still young girls present who were proficient in Go.

"Great! Xiaoyi is also very good at Go."

Amane, who had initially found playing mahjong with Ikeda Nyan and Kataoka Yuuki uninteresting, suddenly leaped to the nearest seat and obediently took her place.

If you can't play mahjong with Nan Yan, then it's pointless.

So it's better to watch my younger sister and brother playing chess happily together.

The three little ones, Kana Ikeda, Yuuki Kataoka, and Maho Yumeno, were also sitting near Iori Amane, and only through Iori's explanation could they understand what they were playing.

During the initial planning stages, neither the brother nor sister spoke.

In the early stages of Go, the opening moves are generally quite conventional. Of course, you can go against the grain, but you also have to bear the corresponding risks. There are countless opening patterns and variations, requiring flexibility.

There's a lot to memorize and practice, so someone who reaches amateur sixth dan at nine years old is considered a top genius.

The initial setup was standard and there's not much to say about it.

However, after only twenty or so moves, the two players clashed in the upper left corner.

Nan Yan raised his head slightly and glanced at his sister, whose expression was half-hidden by her long hair. He knew very well that the person in front of him was today's national Go champion, who was very likely to become the World Youth Go champion in the future. For him, whose Go skills were not very proficient, the intensity of the match was no less than when he faced the peak Akagi.

Therefore, his only chance of winning is to disrupt the situation and then use his superior calculation skills and his sister's mistakes to have a chance of winning.

Therefore, he needs to commit robbery.

The so-called 'ko' is a relatively common type of game. As we all know, in Go, if a stone has no liberties and is completely surrounded, that stone or several stones without liberties will be killed.

However, in Go, there is a situation where a stone can kill an opponent's stone that has no liberties, and the stone that enters the eye also only has one liberty, and can also be killed by the opponent.

If the opponent captures that stone again, a vicious cycle will occur, leading to an endless situation. Therefore, to avoid this endless cycle, the rules of Go specifically state that after a ko fight, if the opponent captures a stone, you cannot immediately recapture it.

We have to go somewhere else before we can bring it back.

This leads to another concept.

That's the loot.

If you take a step elsewhere, the other party can simply ignore you and end the robbery, then your robbery will have completely failed.

If the piece you place has a very high weight, far exceeding the benefits of eliminating the calamity, and you have to take a countermeasure other than eliminating the calamity, then that piece is the calamity material.

However, on the board, the number of ko threats that have greater weight than the ko threat is countable, and eventually the ko will be eliminated by the side with more ko threats; or the side with fewer ko threats may grit their teeth and bear the loss to actively eliminate the ko.

Although the loot can be counted.

However, if there are multiple ko fights in a game, the amount of calculation will increase exponentially.

If his younger sister is eager to eliminate the calamity, then he will be able to gain an advantage, which is the only way he can defeat the national champion.

Having determined his strategy, Nan Yan immediately began his duel with his sister.

Nan Mengke seemed to have anticipated Nan Yan's thoughts and accepted the battle without hesitation.

"At a disadvantage..."

Tian Jiangyi watched Nan Yan make a few more moves, her lips moving slightly.

"Ah, Nan Yan has already fallen behind so quickly?"

"Tell me quickly what exactly happened."

"Haha, the invincible Nan Muyan in the world of mahjong, turns out he can't even beat his own sister in Go?"

"Just kidding, her sister is a national champion!"

"..."

A few days ago, Nanyan played mahjong with Dojima Tsuki and Ikeda Nyan, and he defeated them so badly that they fled in panic. Now, seeing Nanyan at a disadvantage, he is actually a little happy.

Just as Jiang Yi was about to speak, the shrine maiden beside her explained softly, "Well, because Nan Yan has even fewer robbery materials than his sister, it would be disadvantageous to rob him like this."

As a shrine maiden of Kirishima Shrine, Ishido Kasumi naturally also studied Go.

After all, in Japan's upper echelons, Go is considered an elegant art.

If a priestess or a celebrity has studied Go and is skilled in it, she will receive praise from those around her and the appreciation of the chief priest.

Nan Yan lacks sufficient funds for robbery, so continuing to rob will result in significant losses.

"elder brother"

Just then, Nan Mengke forced a bitter smile onto her lips, "Do you remember when we were little? Actually, you not only have a talent for mahjong, but also an exceptional talent for Go."

You've reached the amateur 3-dan level after only one summer of learning Go.

Back then, it was because of you that I embarked on this path.

“I remember.” Nan Yan nodded.

Indeed, he remembered that he had taken classes at his mother's arrangement when he was a child, but he quickly lost interest in Go.

Then, using the Go skills he had learned, he showed off to his sister, defeating Nan Mengke so badly that not a single piece remained on the board.

Generally speaking, even if Ke Jie or AlphaGo were to play against an amateur player, even if there was a huge gap in skill, if you were simply trying to defend your own territory, it would be quite easy.

Just like playing chess against a professional player, even if you move first, you can still gain an early advantage of two knights!
To be wiped out completely is simply bullying someone who doesn't know how to play chess.

Of course, that was when I was very young.

"You gave up Go and switched to Mahjong. In a way, it was a trade-off. You gave up Go but gained a superb understanding of Mahjong. I'm very happy for you."

Nan Mengke seemed to be talking to himself, and without any emotion, he nullified a ko created by Nan Yan, winning the ko. In exchange, Nan Yan was able to place two more stones in other positions.

"It's like robbery; it forces you to make choices, pay a price, and then gain something in return."

So, brother, by giving up those unnecessary things and paying the price that should have been paid, you can become a better version of yourself. Am I right?

"If you had chosen the path of Go back then, your brother wouldn't have achieved what he has today in the national mahjong tournament."

“That’s right, that makes sense.” Nan Yan agreed with his sister’s statement.

If he pursues the path of Go, he might also achieve something great.

He can show off in front of his sister, meet different partners and comrades, encounter strong enemies and difficulties, and of course, gain extraordinary honors in the way of Go.

Compared to these, he is more satisfied with what he has gained on this path of playing mahjong.

"Hehehe"

Nan Mengke is on the verge of turning to the dark side at this point.

It seems that her brother has agreed with her statement.

Then she would use her own methods to clear away all the evils, eliminate adultery, and eradicate heresy for her brother!
Only by abandoning the beauties of the harem and turning to the sacred and noble love can the brother become the perfect brother in his own eyes!
Instead of spending all his time flirting with all sorts of girls.

The perfect brother in the girl's heart has only one lover!
Since Nan Yan couldn't bring himself to say goodbye to these girls, then his younger sister would have to play the villain.

Your brother and sister are doing this for your own good!
Nan Mengke's next attack was incredibly fierce, and Nan Yan could only barely parry it. Even after only sixty or seventy moves, Nan Yan already felt extremely strained.

No!

A profound sense of crisis welled up in Nan Yan's heart.

He is no match for his sister in terms of skill, but ko fighting is his only option, so he must drag his sister into the abyss of ko fighting!

Nan Yan gritted his teeth, determined to fight the battle to the very end.

Looking at the game, Tenjiang and Ishido Kasumi realized that winning the ko fight was Nanyan's last chance.

Bang!
But the moment Nan Yan's piece fell...

The entire room suddenly fell silent.

Even breathing seemed to have stopped.

Whether it was Ishido Kasumi and Tenjiang Yi, who could understand the game, or Nan Yan and Nan Mengke, who were playing the game, they all suddenly seemed to have been frozen in time.

The girls, including Ikeda Nyan and Yuuki, who couldn't understand the game, stared at each other, wide-eyed, not quite understanding what was happening.

Why have they stopped playing?

"Little Ke, wasn't it raining really fast just now? Why did you suddenly take so long to think about it?"

"I don't understand! Can someone explain this to me?"

Dojima Yue was getting a little frustrated. No one had explained the game to her, and as someone who was completely clueless about chess, she was practically blind!
Moreover, the sudden silence from everyone created a very strange atmosphere!

"It's a tribulation of immortality!"

Just then, Tian Jiangyi suddenly spoke up, "This game of chess has turned into a calamity of immortality!"

This is a very rare situation, as special as the three-stage cycle.

The so-called three-ko cycle is the repeated cycle of ko elimination, ko elimination, and ko elimination. If it is a ko, then there is a cooldown of one move before you can capture the stone again, so you need ko threats to fight for it.

However, in the triple ko cycle pattern, the three kos are mutually used as ko threats!
In Japan, the cycle of three calamities is considered a very ominous sign!
This tribulation of immortality is a special existence no less than the cycle of three tribulations.

"What is the Longevity Tribulation?" Ikeda Nyan asked, completely bewildered.

"You should have learned about robbery by now."

Ishido Kasumi explained softly, "Then this 'Eternal Life' ko is a very special type of ko fight."

Three conditions must be met for the occurrence of the Longevity Tribulation.

Firstly, this ko fight is crucial to the outcome of the entire game. In other words, whoever wins this ko will win the whole game. This means that other ko threats are meaningless, because no ko threat is as valuable as this crucial ko fight. No matter the cost, both sides must win this ko.

Secondly, if either party were to proactively attempt to avert the robbery, the losses would be even greater, so neither party should take the initiative to avert the robbery.

Thirdly, both sides in the Longevity Tribulation possess tribulation materials that are inseparable from each other. In short, the tribulation materials are inherent in the tribulation itself. Even if one consumes the tribulation materials sent by the other, the same tribulation struggle will recur, which means that both sides possess unique but infinite tribulation materials.

This means that there are no tribulations outside of tribulations in the Longevity Tribulation, and neither side can actively eliminate the tribulation, because the cost of eliminating the tribulation is too heavy. If they do so, either side will fail, and it can be repeated infinitely, just like the Three Tribulations Cycle.

Everyone has something they need to protect, and they cannot escape each other's tribulations, yet they kill each other, and the cycle continues!
This is the tribulation of immortality!

It was a very unusual board position; even Ishido Kasumi had never seen it before.

This was also because Nan Yan forcibly dragged his sister into the calamity, which led to this unexpected calamity of immortality.

Furthermore, unlike the Three Calamities Cycle, which represents a very ominous sign.

The "Eternal Life" formation is considered an auspicious shape because the characters in the game are mutually destructive and interdependent, creating an endless cycle of life.

"How do we calculate this?" Nan Yan was also encountering this situation for the first time and couldn't help but look at his sister.

The girl stared at the chessboard for a long time, her eyes seemingly glistening with tears, before she understood the feelings Nan Yan wanted to convey to her.

Nan Mengke slowly stood up and turned her head arrogantly: "The rules of the Japanese National Tournament for Go do not have the principle of 'prohibiting the repetition of the same shape in the same game' that is not allowed in Chinese Go. Therefore, this game is considered a draw."

"Consider yourself lucky!"

"call--"

Nan Yan breathed a sigh of relief. Although he didn't know what had gotten into his sister, who suddenly wanted to play chess with him, he had at least gotten through the ordeal.

If his younger sister asked him to dress as a woman, he would embarrass himself in front of so many girls.

A draw is not bad.

It's important to know that Go is unlike chess, where only 0.01% of games end in a draw. Only special situations like a triple ko or quadruple ko are considered to be a draw or a tie.

As for the Longevity Tribulation, not every cycle tribulation can become a Longevity Tribulation, because the value of the tribulation itself must be greater than any tribulation material; otherwise, the side with more tribulation materials will still win.

So, being able to tie with his champion sister, Nanyan felt that he had already won!

However, he still couldn't figure out what Nan Mengke wanted to do by suddenly playing chess with him. He never contacted her when he was usually so free, but only when he was busy.

It can only be said that rebellious girls still have their own little whims.

But for Nan Yan, although his younger sister wasn't cute, she was beautiful, outstanding, and worked harder than anyone else. Her slight willfulness was tolerable, after all, no one is perfect.

And after she finished playing chess, she went to chat with Xiao He, so it seems like there's nothing wrong with her now.

Nan Yan didn't take it to heart.

By evening, the girls had all left, and Nan Yan and Nan Mengke quietly tidied up the house without saying a word the entire time.

This is a kind of tacit understanding between the two, or rather, it's the norm.

After all, both of them are exceptionally outstanding in their respective fields, so there's really nothing to talk about or brag about.

Nan Yan also sighed at this point.

If only my little sister were as dazed as Yumeno, I could show off how amazing I am and she'd say, "Onii-chan, you're so amazing!" That would be so emotionally satisfying!
Unfortunately, such a perfect younger sister, a fantasy of a shut-in, doesn't exist in reality.

Of course, he also loves his very outstanding younger sister, but he just laments that it would be better if she were a little cuter.

After tidying up the mahjong table, it suddenly started raining heavily outside.

The girls should be home by now. Although Dojima Tsuki is a bit arrogant, she is still rich as a young lady from a wealthy family, so she chartered a car to take the girls home.

There are also people who will pick up and drop off your clothes.

So he doesn't need to worry about it.

"I've closed all the doors and windows. Goodnight." Nan Yan yawned, feeling unusually sleepy today.

There was no way around it; Ikeda Nyan, Yuuki, and Dojima Tsuki insisted on giving him money, and he was too embarrassed to refuse. So, Nanyan beat them until they begged for mercy, which was quite tiring, to say the least.

He even played chess with the champion's sister.

A beautiful day has come to an end, and a new day will begin after you wake up!
Nan Yan was looking forward to falling asleep when Nan Mengke suddenly stood in front of him, blocking his way into the room.

"Is there anything else?" Nan Yan asked curiously.

"Ah, Onii-chan," the girl said in a mechanical, emotionless tone, "The rain is so heavy today, I'm so scared. I want to sleep with you tonight like when we were little."

"Oh my god! It's not like it's going to thunder today, and I don't remember you being afraid of the rain."

Nan Yan's expression was strange. Had his sister taken the wrong medicine today?
"Humph!"

Nan Mengke gave a snort, "When Xiao Hehe is afraid of thunder, you hold her tightly and comfort her, and she sleeps soundly under the covers until dawn. But your own sister starts to complain!"

"Can that be the same?"

"What's different?"

The girl looked out the window. "You can sleep with a beautiful girl like Xiaohe and both of you can remain pure and innocent. Why can't you do that with your own sister?"

Nan Yan gave her a deep look: "I'm impressed by you."

A moment later, Nan Mengke comfortably rested her head on her brother's jade arm, a mischievous smile appearing on her lips. However, she obediently closed her eyes, and her breathing became relaxed.

Looking at his sleeping sister, Nan Yan seemed to recall similar times from the past.

Back then, my younger sister was very obedient and adorable. The two of us were very close. With our parents gone, there were only two lonely children in the huge house, and sleeping together like this was actually our daily routine.

But girls eventually grow up to be adults.

Although he sensed that his sister was growing further and further away from him, as her older brother, he still looked forward to witnessing her growth.

He is very proud of his younger sister, who is very outstanding.

But actually, Nan Yan doesn't quite know how to manage this delicate relationship with his sister. However, if his sister wants to be close to him, he can indulge her a little.

But only this once.

"Don't do that again next time." Nan Yan didn't know if his sister was pretending to be asleep, but he just whispered to her and then quickly fell asleep himself.

And after Nan Yan fell asleep.

Nan Mengke's eyes had just opened slightly when she saw her brother's handsome face as he slept soundly, looking completely dazed and unguarded!
The Tribulation of Immortality.

This is the game of chess I played with my brother today.

In Riichi Mahjong, the probability of a Ten-Takatsu (Heavenly Hand) is one in 330,000, but the probability of a Chōsei-Kō (Long Life Seizure) can be as high as one in several million, making it an extremely difficult hand to form.

Some say that if a person plays five and a half rounds every day, it would probably take him sixty-one years to complete a single round.

In the history of Go, the "Eternal Life" ko has only been officially recorded three times.

But more than the rarity of the Eternal Calamity, the girl valued its symbolism.

This chess pattern, with its endless cycle and continuous generation, symbolizes the perfect convergence of favorable timing, location, and human factors.

The girl had previously said that struggles inevitably involve choices; what you give up, you gain in return.

She hoped her brother would give up those women and find the pure and happy life she desired.

She sincerely hoped that her brother could be perfect.

However, the tribulation of immortality gave her a different meaning.

Neither she nor her brother could choose between them; she couldn't abandon her brother, and her brother couldn't abandon her.

The brother cannot eliminate the karmic entanglement between her and her brother through external tribulations, and the same is true for herself.

This foreshadows that the conflict between her and her brother cannot be resolved by eliminating external conflicts to achieve the happy ending she desires.

And more importantly,

In the tribulation of immortality, her tribulation is her brother's tribulation. If she forcibly tries to eliminate her brother's tribulation material, a new tribulation material will be generated. The greatest tribulation material for the two of them is the tribulation itself!
Neither her nor her brother could ever erase the bond and the karmic entanglement between them.

so--

"Brother, I will always be your 'immortal tribulation'."
