Traveling through Gensokyo, but the system is Jujutsu Kaisen?

"Mr. Xiangbei also knows the rules?"

"Understood."

I do understand a little bit. Anyway, just understand it as the power of the world's rules, the power of the laws of nature, balbal, or other abilities in fantasy novels.

"That's good, this way I can explain it faster." Shen Qi sorted out what he was going to say next and spoke.

"The power of the laws within Yakumo Akane's body actually comes from another world, and it's incredibly powerful. Even among those I know who possess the power of laws, her power is extremely strong... Especially since she possesses more than one law within her."

"Originally, this law from another world would have gone unnoticed, because the power of the law within Yakumo Akane was well hidden and very low-key... But, she did something extremely extraordinary, so extraordinary that the entire world's will took notice of her."

"...creating Gensokyo?"

"That's right." Shenqi nodded. "The founding of Gensokyo was also against the will of heaven, and would be interfered with and obstructed by the will of the world. And Yakumo Kurenai shone brilliantly in that battle, fighting back and forth with the Dragon God, who also possessed the power of law."

"The Dragon God was dispatched by the World Will, and thus received special attention from the World Will. With this back and forth, the power of the laws within Yakumo Akane's body naturally caught the World Will's attention."

"Regarding this kind of law from outside the world, whether good or bad, it will cause a huge reaction from the world's will, and the power of the law within Yakumo Hong's body is simply too extraordinary..."

"To use an analogy... in terms that outsiders can understand, external laws are like common pathogens that enter the human body. Once detected, the world's will will resolve them through medication."

"But because the laws within Yakumo Kurenai's body are so powerful, compared to ordinary pathogens, they are more like cancer cells... Once discovered, the world will choose to use chemotherapy and radiotherapy... Is that what it's called? In short, they will use various extreme methods to eliminate the harm in the body."

"If this happens, even a healthy body will be affected. If the laws within Yakumo Akane's body are not erased, the world will be plunged into chaos at best, and even destroyed at worst."

"And the laws within Yakumo Hong's body are deeply connected to her soul, completely unable to be separated. Therefore, we can only destroy the laws within her body and her soul together."

"It was for this reason that Yakumo Hong had to die... She had no choice but to die. In the end, she died at the hands of the Dragon God and Yakumo Yukari."

"Because Yakumo Kurenai's reputation in Gensokyo was so immense, if the monsters and humans heard of her death, it would surely cause a major riot. Therefore, with the combined efforts of the Dragon God and Yakumo Yukari, all memories of Yakumo Kurenai in Gensokyo were wiped out. History was also tampered with, leaving no trace of her."

"I understand." After listening to Shenqi's narration, Xiangbei pondered for a moment and said, "So..."

"Yakumo Kurenai, the hero who helped build Gensokyo, was destroyed because of the laws within her body. As a result, she was killed by Yakumo Yukari and the Dragon God. She should have been beaten to a pulp, unable to be reborn. But for unknown reasons, she came back to life, seemingly carrying a strong grudge. Even if she possessed the body of the Demon Princess, she would not hesitate to crawl back and punch the Dragon God and Yakumo Yukari one by one... Is that so?"

“…Probably… that’s it.”

Shenqi paused and continued.

"Although I sympathize with Yakumo Hong's plight, or rather, I owe her some favors...but this concerns the entire world and Lilith's safety...I, I..."

"Ah, I can understand that." Xiangbei waved his hand to stop Shenqi from saying the next thing.

"Huh... Sorry, I lost my composure." Shen Qi adjusted herself and continued, "However, we were unable to stop Yakumo Kurenai before, and she escaped. Finding her is as difficult as finding a needle in a haystack. But if my guess is correct, Yakumo Kurenai should eventually return to Gensokyo."

"Mr. Xiangbei, I want to ask you for a favor..."

……

……

"Did Xiangbei go back to Gensokyo?"

In the corridor, Mengzi was walking side by side with Xiangbei.

After Xiangbei finished talking with Shenqi, Shenqi was dragged away by Index and the succubus to do a final full-body check-up. Alice took Aige to see Lilith, and Mengzi went to prepare dinner.

Because he didn't have lunch, Xiangbei felt a little hungry, so he thought of going to the kitchen to find something to fill his stomach, so he followed Mengzi.

"Well, I suddenly remembered that I forgot to take care of some things in Gensokyo. I forgot to prepare water and feed for the caged fur balls. Besides, we've had a great time in the Demon Realm for two days. It's time to go back."

Of course, this couldn't really be the reason. In addition to preparing to resurrect Yakumo Hong within three months, there was also Shen Qi's commission.

Shenqi gave Xiangbei a gun, which looked a bit like Gungnir, but was white in color.

Shenqi said that this gun contains a part of her power. She met Yakumo Hong in Gensokyo. If she can help Yakumo Hong in what she can, please help her.

If that doesn't work, and Yakumo Hong has the intention to destroy Gensokyo and even the world... then use this gun to kill Yakumo Hong?

This gun contains the destructive power that is opposite to the creative power, and both belong to the power of law. After the spear is inserted into Yakumo Hong's body, this power will be activated, thereby destroying the law in Yakumo Hong's body.

As a reward, Shenqi gave Xiangbei a book, saying that the book contained all the magical knowledge in the entire Royal Library of the Demon Realm.

After all, he had learned some magic and was considered a half-magician. Xiangbei finally accepted the book and agreed to Shenqi's request.

But he still hoped to return to Gensokyo as soon as possible to prepare everything.

"Is that so?" Mengzi nodded, without any doubt or asking why.

"If Mr. Xiangbei wishes to return, we will naturally not stop him. However, to repay your help, we plan to hold a banquet tomorrow night to celebrate Her Highness Lilith's safe return and to thank you for your assistance... I wonder if you could stay in the Demon Realm for a few more days and leave after the banquet?"

Volume 2: Journey to the Demonic World: Chapter 102: Heaven and Tyrant, Start!

Although Xiangbei wanted to complete the tasks of resurrecting Yakumo Hong as soon as possible, he had plenty of time at the moment. Since the other party invited him to stay for two days, it didn't matter.

So Xiangbei agreed to Mengzi and planned to send him back to Gensokyo the day after tomorrow.

"Oh, right." Xiangbei suddenly remembered something.

"Mengyue and Huanyue, how do you plan to deal with those two guys?"

If you think about it, you can guess that the cause of the incident was probably that Huo used that special prop that looked like the Anti-Prison King handcuffs to control Huanyue's body and threatened Mengyue. The two sisters have a deep affection for each other, so Mengyue would naturally agree to Huo's request.

So even something like assassinating the royal family of the Demon Realm can be done by Meng Yue.

Although this incident was not the fault of the two sisters and was a dispute caused by a disaster, the impact is still bad and some punishment is probably inevitable.

"We're still considering this, but I don't think they'll be subject to any severe punishment. After all, Mengyue and Huanyue are only temporarily learning the rules of the Demon Realm. They're actually under the command of Master Kazami Yuuka."

"Ah, Miss Youxiang's subordinates." Xiangbei thought for a while.

"Mr. Xiangbei, do you know that adult?" Mengzi asked curiously.

"Yeah, I met that guy once before when I accompanied Ai Ge."

"Oh, how is that gentleman doing lately?"

"It's okay. I opened a flower shop in the human world, but I rarely go there. I also have a Kirin monster named Saeki Rin as my adopted daughter."

"I see." Mengzi pondered for a moment and said to Xiangbei, "Mr. Xiangbei, could you do me one more thing?"

Huh? A new event has been triggered?

"Ms. Mengzi, please feel free to say it. As long as it is something I can do, I will do my best."

"No, actually it's nothing serious...it's just the two sisters Huanyue and Mengyue."

The two walked through the corridor and entered a room. The aroma of food filled the air. Mengzi took out a small, exquisitely shaped cake from a cabinet that looked like a refrigerator and handed it to Xiangbei.

Xiangbei took it casually and took a bite of half of it.

"Although the two sisters Mengyue and Huanyue have studied in the demon world for a long time, due to their personalities, or rather, mainly Huanyue's personality... they are rather bad. Apart from that master, they will not listen to anyone, whether it is me or Master Shenqi."

"So even though their maid skills have improved, they have also made many mistakes, big and small, over the years in their search for that master, causing a lot of trouble."

"I understand." He swallowed the cake in his mouth. It tasted okay, much more delicate than the cakes in the human village. "Ms. Yumeko, do you mean that I should take them back to Gensokyo and send them to Ms. Yuuka?"

"Yes." Miss Mengzi nodded and smiled, "It's just right. Taking advantage of this opportunity, I can send them back to that master. This will be a good thing for both the Mengyue and Huanyue sisters who have been away from Master Youxiang for hundreds of years, and for me who has been having to deal with the trouble they cause."

It seems that even if Miss Mengzi is here, she is exhausted both physically and mentally.

He was not very interested in what punishment or treatment Huanyue and Mengyue would receive, but in the original work of Gensokyo players, the Dragon God of Gensokyo lived in a place called Huanmeng Realm.

The Fantasy Dream World is the small world controlled by Mengyue and Huanyue.

Although it is unknown whether the Dragon God really still lives there because of the overlap with the little gods of Gensokyo... However, in order to deal with the matter of Yakumo Hong, I will definitely have to go to the sunflower field. I can take this opportunity to send these two guys over.

"I understand. Leave it to me."

"Thank you very much."

Seeing that Xiangbei agreed very readily, Mengzi breathed a sigh of relief and bowed to Xiangbei.

"It's okay, I just did it for the sake of convenience... By the way, does Miss Yumeko know where Index is?"

"Lady Index should have returned to the Royal Library. Mr. Xiangbei, is there something you want to talk to her about?"

"Well, some small things, I'll be leaving now."

After waving goodbye, Xiangbei left the kitchen. After saying goodbye to Mengzi, he headed towards the library. After saying goodbye to Xiangbei, Mengzi also began to prepare dinner.

The Demon Realm Royal Library is naturally located in the Hall of Ten Thousand Demons... In fact, Xiangbei has always had a question: are these so-called "royal families" and "royal families" really necessary? There are only three royal families in total... and now there are four.

Originally, one could not enter the library without royal status or special permission. For example, Index, as the chief magician of the demon world, naturally had the right to enter the library.

As the person who saved the princess of the demon world, Xiangbei naturally has the right to enter.

Feeling the respectful and admiring gazes from the people in the library, Xiangbei felt a little uncomfortable, but he did not do anything strange. He began to look for Index everywhere.

"Huh? Xiangbei, what are you doing here?"

After searching for a while, Xiangbei saw Index holding some books with magic, and Index also saw Xiangbei coming.

"Are you here to learn magic? You must still be injured. Don't you need to rest for a while?"

Coming to Xiangbei, Index asked with concern... She didn't know why, but since Xiangbei came back, Index felt that her attitude towards Xiangbei had become better?

Was it because he saved Lilith? Of course, after all, who wouldn't have a certain fondness for someone who was capable and responsible?

"It's okay. That minor injury has almost healed." Xiang Bei patted his chest and joked. Except for the fact that the ghost's punch was a bit fierce, it did not cause any damage to the soul. It can be said that apart from consuming some spell power and mental power, Xiang Bei suffered almost no real damage.

"That's fine...Xiangbei, are you here looking for a book? If there's anything you'd like to read, you can tell me. I'm very familiar with this place."

"No, I came here to find you."

"I?"

Index saw Xiangbei bending down and took out a button from the shadow under her feet.

"Remember the curse of Heaven and Binding I told you about before? I actually have a device here that can artificially create this phenomenon... It can trade the magic power of the person who presses the button for a ritual that improves her physical fitness."

"If the magic power is insufficient, the button will consume the rest of the person pressing it as a price to complete the ritual... You mentioned before that as a balance youkai, although you have strong magic power, your physical fitness is extremely poor."

"So I thought this device might be of some use to you."

Volume 2: Journey to the Demonic Realm: Chapter 103: Return

"So magical?"

Index looked at the button in Xiangbei's hand in surprise. Although it had a strange shape, it did contain extremely powerful energy.

As a balanced monster, Index's physical fitness can be said to be ridiculously poor. After all, magic power is not as peaceful as spiritual power and internal strength, and it has the effect of corroding the human body.

This is not a power that ordinary people can master. Unless they are like Alice and Aika, who have a natural affinity for magic, even monsters will be affected by the negative effects of magic.

For example, even though Patchouli gave up her human identity and became a magician, her physical defects did not ease. The same is even more true for Index, who has even worse physical fitness.

If Patchouli is unable to cast magic due to asthma, causing her to be unable to fight, then Index will be unable to bear the excessive release of magic during battle, making her even more miserable than Patchouli.

If it weren't for Shenqi's special care, Index, whose physical condition was getting worse day by day, would probably have been lying in bed counting her eyelashes.

Now, Index, who seemed to have finally found a solution, was naturally surprised and excited.

"Well, but this item can't improve your physical fitness indefinitely. Once it reaches a certain limit, it will no longer be effective. This item is no longer useful to me, so I'll just give it to you, Index."

With a physical fitness level as high as that of a heavenly tyrant, this item is naturally useless to Xiang Bei.

If you give it to Index like this, it can not only increase the favorability of this great wizard, but also increase the favorability of Huo.

Although Huo can do some inhumane things for Yakumo Hong, such as occupying Lilith's body and letting Mengyue assassinate Aika to attract attention, he is still the one who inherited Yakumo Hong's memory, and still treats Index, Rika and others as friends.

So being nicer to Index should also make Xiangbei more cautious about the disaster.

"No, no, this is too valuable. I can't accept it..."

"Take it. I can't use it anyway. If I give it to you, it will be of great use. As a prop, it can be considered as a good use of it."

"Of course, this tool isn't without its dangers. It's best to experiment with it on some guinea pigs before using it yourself. It's up to you to keep it or return it after use."

He forcefully stuffed the button into Index's arms, then Xiangbei took out a white cloth, danced with it, and disappeared on the spot.

Index opened her mouth, holding the button in her hand, staring blankly at the place where Xiangbei disappeared. She stood there for a while and laughed out loud.

"Ahhh, Xiangbei, this guy is really... Well, this is a big favor I owe him. I don't know how to repay him."

However, she did not look unhappy at all. She hummed a song and walked into the study room nearby.

……

……

"I plan to go back to Gensokyo the day after tomorrow."

"Ah, Xiangbei, do you want to go back?"
