In the last days, safety will always be the most important issue, even more so than food and water. After that happened, Yubai paid more and more attention to the security of Yang Dangshan.

To Yubai's surprise, Xu Chuang, who had killed Cheng Tao's mother before, was a well-known architect before the end of the world, and after the escape of Jiang Li and Jiang Zheren, he found Yubai, mentioned his identity, and offered to build a wall on Yang Dangshan to protect himself.

Yubai's eyes lit up when he heard what Xu Chuangxin said, he didn't expect that this person who seemed to be a cowardly person before would be an architect. This is really sleepy, someone will send pillows, Yu Bai is worried about the security of Yang Dang Village, it is when he is at a loss, Xu Chuang's appearance also let him know what to do next, that is, to build a wall.

It's just that Yubai doesn't know what Xu Chuang's level is, and whether he can take on this responsibility remains to be considered. How can the wall withstand the impact of zombies, not even just zombies, Yubai has never forgotten the threat of mutant beasts, in the current Yubai opinion, mutant beasts are even more threatening and destructive than zombies. If the walls built are not enough to resist the attacks of zombies and even mutant beasts, then everything is in vain.

Yu Bai solemnly pulled Xu Chuangxin to tell him in detail about the specific situation of zombies and mutant beasts, as well as some of his guesses. When he heard Yu Bai say that in addition to zombies, there are also mutant beasts in the end of the world, and there are even more terrifying species such as mutant beasts, he was shocked at first, and then couldn't help but think that if they encountered even one mutant beast before Yu Bai arrived, he was afraid that the entire Yang Dang Village would be in a desperate situation.

When Yubai asked him if he could build a wall that could withstand the attack of the mutant beast, he regained his composure and looked confident again, as if he was the real him only when he mentioned this.

Yu Bai saw him with such a confident appearance, and he also had a little trust in him in his heart. Perhaps it was the ordinary life in Yangdang Village in the previous month that buried his talent as an architect.

Yes, Xu Chuangxin is a very good architect, before the end of the world, he is a successful person in the eyes of everyone, and he has a deep knowledge in architecture, because he is not very old, this has also become his boasting capital, and he is usually attracted the attention of the people around him, and there are countless halos around him. But with the advent of the apocalypse, order collapsed, and his former glorious past seemed to have no effect.

The acquaintances around him have either become zombies or have been eaten by zombies. His former identity no longer seems to bring him anything. No one will give him an extra piece of steamed bun because he is an architect, and no one will give him an extra sip of water because he is a successful person.

Especially when he first fled to Yang Dang Village, he was like everyone else, in order to survive and eat, he did some manual work here, although he did not discriminate against people who did manual work, but he always felt that people like him with a skill should do more meaningful things, but before Yubai arrived, his knowledge of architecture was completely useless.

At this time, in his opinion, Yubai is the same existence as Bole, which also makes his heart suddenly brightened. Of course, Yubai is Bole, and whether he is really a thousand-mile horse remains to be considered.

…………………………

Xu Chuangxin took some people arranged by Yubai and began to build the wall in an orderly manner, and Yubai was naturally not idle, he knew that if humans wanted to defeat the apocalypse, they needed to make all humans, at least most humans, stronger. Yubai has never believed that the earth, which gave birth to human beings, will bring such a catastrophe to mankind, and there will be hope.

In fact, these days, Yu Bai is also wondering whether the previous legends about martial arts are true, whether those chivalrous people who fly on the eaves and walk on the wall, such as empty children and elves, really exist, and even those legendary powers in ancient times also really exist?

If not, are all those accounts false? If so, then why has such a master never been heard of in modern times? And where are those legendary martial arts cheats, if the current human beings can practice a little, although they still can't resist the zombie virus, but the ability to fight zombies and even mutant beasts can also be greatly improved.

Yu Bai didn't think too much about whether there was martial arts in the past, whether there was or not, it had nothing to do with him now, after all, it had become history, and what Yu Bai wanted to do now was to follow the example of his predecessors and create a kind of martial arts that belonged to modern people.

It's not that Yubai can't do what he can't do, and he wants to do something that many people haven't done. It was really Yu Bai who had gone through the previous battles and the real changes in his body, especially when he faced two mutant cats at the same time, the kind of state he entered made him believe that martial arts really existed, and Yu Bai did not intend to cherish himself.

Yu Bai guessed that in the previous modern society, it may be the so-called era of the end of the law, and no martial arts can be practiced, because the air does not contain any energy at all. And when it came to the end of the world, Yubai found that with the arrival of the end of the world, in addition to the blood in the air, there seemed to be more aura, maybe this is the opportunity for human beings to turn over?

He believes that other human beings, even if their bodies are not strengthened like him, can learn a little fur, and can greatly increase their self-preservation ability, and now Yubai just wants to write down all his feelings, and then let Xu Xiaoyue learn it, let Yang Yuyang learn it, and let the people in Yang Dang Village learn it. Even......

So, Yu Bai wrote the name of his sword technique in the booklet: Cloud Turning Nine Slashes. Although Yu Bai can only slash 4 times in a row now, it should be called the Four Slashes of the Clouds, but Yu Bai believes that he will never stop there, and the so-called nine is the extreme, and the nine slashes should be the limit of this knife technique.

"There is a mixture of things, born congenitally, lonely, independent and unchanging, circumference and not death, can be the mother of the world.

I don't know its name, the strong word is called the way, and the strong name is big. The big is gone, the past is far away, and the far is reversed.

Therefore, the road is big, the sky is big, the earth is big, and the people are big. There are four major domains, and people live in one of them.

Man is the law of the earth, the earth is the law of the sky, the heaven is the law, and the Tao is the nature. ”

The Tao is natural, the knife is natural, Yu Bai doesn't know how he wrote such a paragraph, but when he wrote, he naturally wrote this paragraph of mysterious and mysterious words, Yu Bai didn't know that he inadvertently wrote down the total decision of the Nine Slashes of the Clouds, in fact, it faintly contained the truth of heaven and earth.

Then, Yu Bai's whole person seemed to be excited because of the paragraph he had just written, and he wrote down the first form of the nine slashes of the clouds in the booklet: dense clouds and no rain, the second type of clouds and rain, the third type of rain and wind, and the fourth type of vigorous and resolute.

This is also the limit of what Yubai can write down at this stage.
