When Ye Xiao arrived at the fourth floor, he clearly felt that there was a layer of restriction in the library.

Most of these restrictions are in the form of formations.

The so-called formation is a special energy generated by using specially refined ores and running along a certain route.

This special energy has both offensive and defensive forms.

But no matter which form it is, it can unleash tremendous power.

The formation is the protective umbrella for the high-level skills hidden in major libraries, and it is also the first line of safety.

Therefore, they are usually contracted and constructed by the top formation masters of the Jiuzhou Alliance.

This is why, even though Yang Zhengyi was a grandmaster before, he couldn't easily steal the martial arts skills.

However, Ye Xiao had a certificate issued by the curator, so he could easily enter the fourth floor.

There are quite a few people on the fourth floor, even a little too many.

There are probably one or two hundred people.

These numbers are definitely not enough compared to the ones below, but the strength of every person here is at least above the fifth level of the acquired realm, and does not include the fifth level of the acquired realm.

In other words, these people are the backbone of Jianghai City.

In the next few decades, it is very likely that they will advance to the Grandmaster level.

When Ye Xiao arrived, many eyes fell on Ye Xiao. Seeing that he had only revealed the realm of the second level of the acquired realm, they couldn't help but raise their eyebrows slightly, with some doubts.

He seemed to be wondering how a second-grade acquired trash like him could be qualified to enter the fourth level?

Ye Xiao ignored the crowd and walked straight over to start looking for the books he wanted.

It’s no wonder that there are quite a few surprises on the fourth floor.

Ye Xiao had just arrived in front of one of the bookshelves and stretched out his hand to place it on one of the books. The next second, the golden book soul in his body began to beat violently.

This made him slightly stunned, but then he was delighted and reached out to take it out.

That is not a book on weapon refining techniques, but a book on boxing.

Ye Xiao had practiced some boxing before, but he didn't find many basic techniques, only two books.

I didn't expect to find the third one here.

He studied it quickly, imprinting it in his soul.

Afterwards, he continued to search for the technique of refining weapons.

During this process, he would occasionally come across a basic set of skills from another series that had not yet been included in the Golden Book.

Ever since Ye Xiao started practicing the Taixuan Tiangang spiritual technique, his brain has become very active, like a computer.

So he clearly pointed out that the probability of shipment here is higher, about ten to fifteen times that of the ones below.

In other words, you have to read ten thousand books to find a basic technique below, but here, you may only need to read a thousand books to find one.

If you think about it carefully, the skills here are all above the extraordinary level, while the ones below are basically ordinary level skills.

The recording, copying and evolution of martial arts requires the martial artist to have sufficient experience and a certain level of skill.

Ordinary skills have a low entry level, so many people must have copied them.

Some acquired third or fourth level martial artists may be able to adapt an ordinary-level martial arts technique.

As for the extraordinary level, it requires a master above the grandmaster level to adapt it.

In this way, the number of exercises is greatly reduced.

Invisibly, a large number of useless books were deleted for Ye Xiao.

Although the extraordinary level skills are definitely a little slower to read than the ordinary level skills, for Ye Xiao, this slight difference is not a big deal.

After all, his cultivation level is very high, and he can master it quickly with a little understanding.

However, what Ye Xiao was mainly looking for was the art of refining weapons.

In half a day, he found the basic skills of about three weapon refining techniques.

However, the Golden Book's soul has not yet emitted a faint fluorescence. I wonder how many more steps it needs to take to break through and merge.

"Duang~!"

Soon, the library's closing bell rang. Although Ye Xiao did not have to go to work today, he still had to leave when the library closed at night.

After simply packing up his things, Ye Xiao followed everyone and left the fourth floor.

With the certificate issued by the curator, I guess I will be lucky enough to come to the fourth floor from time to time to read for a while in the next month.

Delicious.

However, when Ye Xiao walked out of the fourth floor and came to the hall below, the sound of sirens was heard at the door.

Then, several garrison members rushed in.

Ye Xiao couldn't help but raise his eyebrows slightly.

"What's going on?"

Gu Hai glanced at him in the crowd, then quietly walked up to him and reminded him.

"Old Ye, leave quickly. Your library has detected the presence of a star beast."

Ye Xiao was slightly startled. Is there a star beast fluctuation in the library?

How come he didn't feel anything?

Just as I was confused, suddenly, a silver-white fox figure jumped out from the upstairs.

"That's it! There it is!"

"Quick! Catch him!"

The entire library was instantly thrown into chaos.

People rushed outside frantically, while the garrison members chased the fox frantically.

The silver-white fox glanced at the crowd, his eyes filled with pain and sadness.

There were even traces of tears in its round little eyes.

But when its eyes met Ye Xiao's gaze, they suddenly shrank and then immediately jumped away.

The look became flustered and self-blaming.

It seemed that it didn't want Ye Xiao to see it like this at all.

But Ye Xiao understood.

That's not a star beast, that's Ning Yuhen! Ning Yuhen is the mysterious vein of the silver fox clan, and the last time, when King Ai'er's soul possessed him, he did something to gradually stimulate the silver fox star beast bloodline in his body.

Once the star beast bloodline of human beings is activated, it is very likely to devour the bloodline of the human race and turn into a star beast.

This is also the reason why countries around the world are very wary of orcs.

Because no one knows when they will become unstable and why they will undergo drastic changes.

However, didn't Ye Xiao already use the healing technique to suppress Ning Yuhen's silver fox bloodline? Why did it fail?

At that time, he had used his mental power to search thoroughly, and King El had not left any mental imprint, so it was impossible for him to cause any changes to Ning Yuhen.

At this time, the commotion in the library had gradually stopped, leaving only some aftertaste.

The members of the garrison team all chased in the direction Ning Yuhen fled.

Even if Ye Xiao used his toes, he could guess what would happen to Ning Yuhen if he was caught.

After a brief thought, Ye Xiao followed everyone and left the library.

Third update, thanks to my book friend Shengshi Xiaozu for the reward, thank you very much.

I'm saving the draft and will update it later.
