When Ye Xiao arrived at the fourth floor, he could clearly feel that there was a layer of restriction in the library.
That type of restriction was mostly a type of array formation.
The so-called array formation was a special energy that was produced by using specially-refined ores that operate in a certain route.
That special energy had both offensive and defensive forms.
However, no matter which form it was, it could erupt with tremendous power.
The array was the protective umbrella of the high-level cultivation techniques hidden in the various areas, and it was also the first line of safety.
Therefore, it was usually contracted and built by the top array experts of the nine provinces alliance.
That was also why, although Yang Zhengyi was a great grandmaster, he had no way of easily stealing the cultivation technique.
However, Ye Xiao had the director's approval, so he could easily enter the fourth floor.
There were quite a number of people on the fourth floor, and there were even a little more than he thought there would be.
There were about 100 to 200 people.
Those people were definitely not enough to compare to the people below. However, every single person here was at least above Houtian fifth grade, and that did not include Houtian fifth grade.
In other words, those people were all the prodigies of Jianghai city.
In the next few decades, it was very likely that they would advance to the Xiantian realm.
When Ye Xiao arrived, many gazes fell on him. When they saw that he had only revealed his Houtian second-grade aura, they could not help but raise their brows slightly, feeling somewhat puzzled.
Of course, they were confused. How could Houtian second-grade trash like him have the qualifications to enter the fourth floor?
Ye Xiao did not bother with the crowd. He walked straight over and began to search for the books he wanted.
Needless to say, there were many surprises on the fourth floor.
Ye Xiao had just arrived in front of one of the bookshelves. He had just extended his hand and placed it on one of the books. In the next second, the divine soul's Golden Book in his body twitched violently.
That caused him to be slightly stunned. Immediately after, he was delighted and reached out to take it out.
That was not a book on the art of armament refinement, but a book on strike techniques.
Ye Xiao had cultivated a little on strike techniques before, so he did not find many basic cultivation techniques. There were only two books.
He did not expect to find the third book here.
He studied it very quickly and imprinted it in his divine soul.
After that, he continued to search for artifact refinement techniques.
During that process, he would occasionally encounter a basic cultivation technique that was not included in the other series but was not included in the Golden Book.
Ever since Ye Xiao cultivated the Big Dipper's Grand Myster spiritual cultivation technique, his mind was very active, like a computer.
Therefore, he was very clear that the distribution rate here was even higher. It was about ten to fifteen times higher than below.
In other words, one could only find a basic cultivation technique by reading 10,000 books below. In that place, one might only need to read 1,000 books to find one.
Thinking about it carefully, it made sense. These were all cultivation techniques above the transcendent level, while the ones below were basically all ordinary ones.
The carving and evolution of cultivation techniques required the warrior to have sufficient experience and a certain level of skill.
Ordinary cultivation techniques had a low entry-level foundation, so there would definitely be many people who copied them.
Some Houtian third or fourth-grade martial artists might be able to adapt ordinary cultivation techniques.
As for transcendents, they needed experts above the grandmaster rank to be able to adapt them.
That way, the number of cultivation techniques would be greatly reduced.
Unknowingly, a large portion of the discarded books had been deleted for Ye Xiao.
Although transcendent-level cultivation techniques were definitely slower than ordinary-level cultivation techniques in reading, to Ye Xiao, that small difference was almost negligible.
After all, his cultivation was already very high. With just a little comprehension, he would be able to grasp it very quickly.
However, what Ye Xiao was mainly looking for was still the artifact refinement techniques.
In half a day's time, he found roughly three more basic cultivation techniques for artifact refinement.
In that way, he already had eight basic cultivation techniques for armament-refining techniques.
However, the divine soul's Golden Book had yet to emit a faint fluorescent light. He did not know how many more were needed before he could synthesize.
Ding!
Very soon, the sound of the bell rang signifying the library's closing. Although Ye Xiao did not go to work today, he still had to leave when the library closed at night.
After briefly packing up his things, Ye Xiao followed everyone and left the fourth floor.
With the approval given by the director, he estimated that he would be blessed in the next month and could come to the fourth floor from time to time to read.
It was wonderful.
However, when Ye Xiao walked out of the fourth floor and arrived at the hall below, the sound of a siren came from the door.
Following that, several garrison team members swarmed in.
Ye Xiao could not help but raise his eyebrows slightly.
"What's going on?"
Gu Hai glanced at him from the crowd and quietly walked forward to remind him.
"Old Ye, leave quickly. Your library has detected the fluctuation of a star beast."
Ye Xiao was slightly startled. There was a fluctuation of a star beast in the library?
Why had he not sensed it?
Just as he was in a daze, a silver-white fox figure suddenly jumped down from upstairs.
"That's it! It's over there!"
"Quick! Catch it!"
The entire library was instantly thrown into chaos.
People frantically rushed out while the garrison members frantically chased after the fox.
The silver-white fox swept its gaze across the crowd. Its eyes were filled with pain and sadness.
There were even traces of tears appearing on its small eyes.
When its eyes met Ye Xiao's gaze, it suddenly shrank and immediately jumped away.
That gaze became flustered and self-reproachful.
It was as if it did not want Ye Xiao to see it like that at all.
However, Ye Xiao understood.
That was not a star beast, that was Ning Yuhen!
Ning Yuhen had the Silver Fox clan's profound bloodline. The last time, when King El's soul body possessed him, he had done something that caused the Silver Fox star beast bloodline in his body to gradually activate.
Once the star beast bloodline was activated, it was very likely to devour the human bloodline and have them become a star beast.
That was also the reason why all the countries in the world were very wary of the beastmen.
That was because no one knew when they would become unstable or why they would undergo a huge change.
However, Ye Xiao had already used a healing cultivation technique to suppress Ning Yuhen's Silver Fox bloodline at that time.
Why did it lose its effect?
At that time, he had already used his spiritual energy to search. King El had already left no mental imprint, so it was impossible for him to change Ning Yuhen.
At that moment, the commotion in the library had already gradually stopped, leaving only a few lingering sounds.
The members of the garrison team all chased in the direction where Ning Yuhen had escaped.
Ye Xiao could guess what would happen to Ning Yuhen once he was captured.
After thinking for a moment, Ye Xiao followed everyone and left the library.
