I'm in the Teyvat running group

Based on the information I just received, Jean and Diluc have already reached the ninth ring, and I also noticed a few days ago that Arecino was on the verge of advancing.

The greatest advantage of the spell system lies here: its most crucial significance is that it provides a clear and understandable path to advancement.

Why is it that in the world of Teyvat, the human body is so powerful, which should be a shortcut to mastering elemental power, but why is it that it is still devoured by elemental power, and why is the Eye of God even a blessing?

One reason is that the elemental forces are too violent, so the Eye of God must be used as a medium.

On the other hand, the Eye of God also locks down Teyvat's development system, causing the Teyvats to gradually fall behind in the exploration of the essence of power and stagnate on the path of materialism.

What is the biggest difference between materialism and idealism? The answer lies in reproducibility.

Calculus, even in the world of cultivation, can be considered the entry point for advanced experts. At least in the mage system, the spell runes with the difficulty corresponding to calculus are roughly fourth-ring spells.

A normal human being, with the help of good teaching materials and excellent teachers, can learn and master calculus step by step, starting from 1+1, over several years.

This means that even if a person only accounts for one percent of the total population, the Fourth Ring Mage has the potential to be replicated.

If Teyvat didn't have the Vision system, but instead relied solely on elemental or light-based powers, then through generations of trial and error and improvement, a Teyvat system would eventually emerge, much like magic.

However, the appearance of the Eye of God has locked down this system, and most people's goal will become to find a way to activate the Eye of God.

Although materialism and idealism are not inherently superior or inferior once a certain point is reached, this is not the case in the overall development of civilization.

If Liyue were given 30 or 40 years to develop, it wouldn't be surprising to have hundreds of legendary spellcasters among hundreds of millions of spellcasters!

“But there’s definitely not that much time left for development now…” Yunxiu sighed.

"What development timeline?" Tsukihime asked, blinking her big eyes. "Is it the upcoming Divine Cherry Blossom Exorcism?"

"No...but it doesn't matter anymore, I'll tell you later." Yunxiu patted Yueji's head and smiled as she returned to her room.

As for how far the Divine Sakura Purification would ultimately go... he didn't want to think about it for the time being; he wanted to rest for at least one night.

-----------------

Early the next morning, Yunxiu set off with Yueji and Sasa Yuluo to Haiqi Island and Yuanxia Palace to set up the formation.

As key locations where an outbreak is highly likely, Yuanxia Palace and Haiqi Island are of paramount importance in this formation. Therefore, Yueji, currently the strongest among them, will be stationed here.

Yunxiu and the Tengu clan's general will continue to set up formations in other places. Eventually, Sasa Yulu will be stationed at the Yuying Furnace in Tasasa, while Yunxiu will return to Narukami Island to preside over the formation with Kozai Palace.

As for the formation itself, Yunxiu had already made careful preparations.

The most crucial element is the fusion of the Imprisonment Technique and the Rainbow Light Wall, used to filter out the energy that can penetrate the array. Then, the Resonance Technique guides the calamity energy.

Next, the calamity will be filtered out first using the Justice Exorcism, and then the purification array will be used to transport it to the Divine Cherry Tree. As for the connection between the array and the Divine Cherry Tree, in addition to the fact that the Divine Cherry Tree itself is connected to the ley lines, it also requires the assistance of the interdimensional gate.

The combination of six different ninth-ring spells is something only a powerful individual like Yunxiu, whose intelligence bonus in spell development is currently as high as 38 (17×2+4), could achieve.

Of course, it was quite difficult even for him.

Besides completing the mission of exorcising the divine cherry blossoms, this is also a preparation for saving Shenhe in the future using six legendary spells.

While it certainly won't be on such a massive scale, there will actually be many more details and issues to address.

The formation for setting up Haiqi Island went smoothly and was completed quickly.

However, just as he finished setting up the formation at Yuanxia Palace, the shrine maiden from Yuanxia Palace named "Aqi" found him.

"Lady Yunxiu, our 'Current Human God Priestess' invites you to a discussion. Please follow me."

"Can I bring people with me?"

The woman named Agi glanced at Tsukihime and Sasa Ayura and said, "Only one can be chosen."

"Lady Sayuro, please wait here for a moment." Yunxiu, holding Yueji's hand, quickly caught up with the shrine maiden wearing a strange mask.

It was the same route as last time.

Soon, they met Serania sitting on the steps at the entrance of the shrine.

Chapter 161 Inazuma's Greatest Crisis! (First Update on Thursday!)

Today, instead of wearing the robe that covered her up completely, she wore a rather simple dress that perfectly showcased the dragon's curves.

I don’t know if it’s just my imagination, but the horns on her head look a bit bigger. Although her body is not much different from that of a human girl, you can clearly see a few scattered scales on her arms.

Yunxiu finally saw the moon wheel hanging around the girl's neck—it was a strangely shaped moon wheel with lightning element.

Seeing Yunxiu approach, she didn't get up, but continued to play with the pretty little knife in her hand until the two of them were right in front of her, at which point she looked up at them.

"You've come..." Serania exclaimed in surprise, seemingly noticing Tsukihime behind her, "Are you that 'Doll'?"

"What 'doll'?" Tsukihime glanced at Serania and asked curiously, "What kind of demon race are you descended from? I've never seen one before."

Um... Seeing that the two girls had started staring at each other and even Yue Ji was baring her teeth, Yun Xiu helplessly walked between them, blocking Serania's view.

“Miss Serania, is there anything you need to tell me?” Yunxiu gently squeezed Yueji’s palm and said to Serania, “Inazuma is going through a very difficult time right now, and it’s already quite difficult for me to find the time to see you.”

“I know what you’re doing.” Serania put away the knife and answered methodically, “But this matter is not so simple, and you are not prepared enough.”

"Not enough... what does that mean?"

“Literal meaning,” Serania added, “Besides the ‘Dark Sea’ you mentioned, the Abyss Palace will also be a flashpoint.”

Could Yuanxia Palace also be a flashpoint? Although this was not unexpected for Yunxiu, the news was still quite alarming.

If we're really short-staffed, then we're in trouble...

Seeing the still somewhat confused looks on Yunxiu and Yueji's faces, Serania explained:

"Five hundred years ago, Ilmin, the last emperor of the Black Sun Dynasty of Kanria, summoned a power from beyond the heavens and opened a gap in the barrier of the world. You all know about this, right?"

"I know, but what does it matter?"

"A powerful human stepped forward and used extraterrestrial power to create a reversal magic array, sealing the breach, but also causing widespread pollution..."

"We know that too."

“Alright, then you should be able to figure out one thing: since Teyvat is interconnected internally…” Serania drew two circles on the ground and said, “then it must be interconnected externally as well…”

"So, you mean that the demons that originally planned to invade through the gap in Sumeru will instead invade through the Abyss Palace?" Yunxiu's face turned very ugly when she heard this. If that were really the case, it would indeed be a big problem.

"They might also come from the Dark Sea, but my advice is that you should focus on the Abyss Palace." Serania said calmly, "The Abyss Palace is not only inhabited by kind-hearted dragonborn and remnants, or in other words, the kind-hearted are the minority."

She made an upward gesture and said, "The kind-hearted dragonborn and the remnants went up together when the Sea God Island rose in Orobas. Those who remained, except for people like me, were all beings who were unwilling to integrate into human society."

If it really is a massive invasion of demons from Fukushita Palace, then Inazuma's current manpower is indeed far from sufficient...

Even during periods of calm, nearly ten legendary figures are stationed around the Death Domain of Sumeru, and during periods of outbreak, the number approaches thirty!

Moreover, the Great Compassion Tree King is almost unable to leave Mount Sumeru and must pay attention to it at all times. In Inazuma, there are actually only two gods and seven legends. Even if you count Yunxiu and Ying as one, there are seven at most.

Even considering that the entrance to the Abyss Palace can't be too big, and the wave of monster attacks won't actually be too intense, we'd still need to at least double the current manpower just to be barely enough...

Frinna is still in Inazuma. As long as Agoria agrees, it's equivalent to having a legendary peak-level player. As for the rest... we can only rely on Raiden's face-saving fruit.

Yunxiu didn't waste any more time and quickly returned to Narukami Island with Yueji, where they met with Raijin at the castle tower.

The two sisters were just about to set off for the Dark Sea when they received such terrible news, and they were both quite shocked.

"Is this news reliable?" Lei Dianzhen was no longer as calm as usual, and stood up to look down at Yunxiu.

“If they are indeed dragon descendants from the Abyss Palace, then it should be reliable.” Lei Yingdong stepped out of the shadows, and said more calmly than her sister, “The descendants of Orobas are not particularly treacherous, and they have no reason to tell such a lie.”

Yunxiu considered it carefully before continuing to the Leidian sisters: "If possible, I hope that you two, especially Lord Leidian, can stay in Yuanxia Palace and entrust the Dark Outer Sea direction to a powerful member of the Familia level."

"Oh? Why is that?" Raiden asked, puzzled. "If the outer sea direction of Darkness is quickly breached..."

“It’s easier to deploy defenses in the outer sea of ​​Darkness, but it’s much harder in Abyss Palace.” Yunxiu opened the map of Abyss Palace and Haiqi Island and said, “It is very obvious that it is almost impossible to transport large war weapons into Abyss Palace, but it is not the case near the outer sea of ​​Darkness.”

He zoomed out the map and brought up the entire map of Inazuma: "Especially since Tsuruga has recently calmed down, we can transform Tsuruga into a war fortress, and with the support of a fleet and powerful members of the Familia level, as long as no Demon God-level beings appear, we can completely resist them."

Raiden and Raiden looked carefully at the map of Heguan and then fell into deep thought.

Of course, making a judgment is not difficult for a god. Soon, Lei Dian Zhen figured it out. She glanced at Yun Xiu and said, "Is it feasible to modify the war fortress?"

“It’s feasible. The only problem before was the lack of a central commander, so even during the great battle in Liyue, the command was divided.” Yunxiu sent a message to Yunzhi from the Spirit Realm, urging him to come to the Castle Keep as soon as possible, before continuing:

"But now, we have a professional war fortress commander who is fully capable of building large-scale battle fortresses."

"commander?"

He'll be there soon.

The group waited for a while, and less than fifteen minutes later, a huge robot arrived, guided by Aojie. It was Yunzhi, who had just been created by Yunxiu a few days ago.

Raiden carefully stroked the robot's shell before exclaiming in realization, "This must have been made based on something from that other world!"

“Yes, he was a command chip for a war fortress before.” Yunxiu patted Yunzhi’s head and continued, “The problem now is how many powerful members at the level of a familiar can we invite to withstand the pressure from the Dark Sea.”

"I will recall Inazuma's Nagi, who is stationed in Sumeru, and then discuss the support for Fukaros with the Water Ruler." Raiden Shin held up a few fingers and calculated for a moment: "Even if I invite two more strong people from Liyue, that's the most I can find."

She paused for a moment, then continued, "Both Minagi and Fukaros possess strength approaching that of a ruling god. If nothing unexpected happens, Liyue can invite Kaiyangxing and Xiaoyue Zhuyang Zhenjun, both of whom are also extremely powerful."

Yunxiu nodded. Three of these four possessed strength approaching that of a ruling god. Even if they weren't skilled in combat, they were still considered formidable among legendary powerhouses.

Kaiyangxing is slightly inferior, but he should not be underestimated. At least in a one-on-one situation, neither the former Doctor nor Ba Che, who is still unknown when he will win the resurrection match, may be able to deal with Kaiyangxing.

The only human stronger than him is probably Captain Capitano.

For Inazuma now, the support of these four is likely to be far better than the arrival of ten ordinary legendary powerhouses.

"Then let's all prepare ourselves." Raiden Shin raised his hand and summoned a sword that shimmered with light, handing it to Yunxiu. He said, "Take this sword. You can represent me in Inazuma. Return it to me when the war begins."

Yunxiu took the Thunder God's sword "Dream of One Heart," and was about to make a check to see the effect when she discovered that the blade was covered by a stream of light, which couldn't penetrate at all...

With a helpless sigh, Yunxiu bowed and then hurriedly left with Yunzhi and Yueji.

"Yunzhi, with the current resources and manpower, can you deploy a sufficiently powerful combat fortress in Heguan?" Yunxiu glanced at Yunzhi, seeing that he still seemed somewhat confused, and couldn't help but ask, "If possible, what resources would you need?"

With the current resources, we can only build a framework and set up the most basic version at best.

"What if there are four more powerful individuals whose energy level is close to that of Tsukihime? Plus about two hundred Return Machines."

It will be much better than the most basic version, but it still won't be able to support very high-intensity battles.

"Then how do we do it?" Yunxiu asked in confusion, "Just how powerful can your battle fortress be?"

<My battle fortress briefly held off a "King Insect" until it was slain by the Great Commander.>

"What if the monsters we face are at most like Yue Ji's level?" Yun Xiu pointed to the map and showed it to Yun Zhi. "Of course, there are at most four strong ones."

"In that case, we'll also need an energy core and a magic array. I understand that the main system in this world is 'magic,' and I've already devised a plan for you based on the information I've gathered."

Soon, a window popped up from the side of Yunzhi's body, and thousands of drawings flew out one by one, quickly stacking into piles of documents. The one placed at the top was the so-called "Heguan Fortress Project".
