In the midst of many stunned sights, Yue Yu slowly opened his eyes, and the original black and white pupils were also dyed with an emerald green color at this time.

And in the next moment, his left hand quickly made a movement similar to a Taoist mudra, and spat out a strange syllable in his mouth. Immediately after that, the wood aura around Yue Yu's body began to spread out one after another with tiny silk threads.

At first, there was no movement, but with those green and green aura, it entered the floor and the surrounding bookshelves. Everyone in the building saw thousands of tiny wooden thorns, which suddenly stabbed out quickly from those smooth wooden planks, and in less than an instant, almost all the space within half a zhang of Yue Yu's body was covered.

"Third brother, could this be the secret method in the silk winding palm? In addition to the wind system secret method, he can even use the wood system?"

Another old man with a white beard stood beside the old man in a brown shirt from before, his eyes full of surprise. "How much surprise does this little guy want to surprise us?"

"Looking at it like this, it's probably a silk winding spell. However, compared to his ability to use the secret art of the wood system, I was even more surprised by his ability to learn this silk spell as soon as he learned it. Which of us at the beginning didn't take more than ten years to barely be able to use it?"

The gray-haired and brown-shirted old man, who was called the third brother, first let out a long breath, and then waved his hand with a complicated expression. "This little guy is really too bold! Go down to the bottom, from now on, this building will be temporarily closed! All the people present in the building just now will also be detained by me first!"

"Seal the building?"

There was a moment of astonishment on his face, but then, when the white-haired old man's gaze swept over the already battered wooden planks on the ground, there was a hint of clarity in his eyes. In fact, even if there are no holes caused by these sudden silk winding spells, for the sake of that case, the people reading the books downstairs can't just leave. Don't let anyone else enter the building at this time.

- Although the next time was supposed to be the time for those elite disciples who were defeated in the Great Competition to come to the library to choose books and take a break. But for now, it can only be put on hold for the time being. At this moment, there is nothing more important than covering up the reckless behavior of this little guy just now.

Thinking of the outside of the building, I don't know if there are other high-level martial artists passing by here, and if anyone can sense the spiritual power fluctuations here, the white-haired old man only felt a pain in his brain.

However, although there are many troubles, in the eyes of the old man, they are still full of surprises.

"It's easy to block the news! The problem is that the wood species suitable for this silk entanglement spell are hard to find, but I'm afraid that in the next two months, we will have to make a special trip to Licheng for him—"

Yue Yu was completely unaware of the conversation that was happening around him, and all his attention now was on the secret technique he was using. And the auxiliary intelligent system in the body is also recording every moment of the Silk Winding Spell in detail.

The tiny silky wooden thorns in the surrounding space were still swelling wildly. It wasn't until he had exhausted the wood aura that he had lost his support and collapsed.

And looking at the wood dust and debris all over the ground, Yue Yu couldn't help but frown slightly. These wooden thorns just now were somewhat similar to the kind of tusked demon elephant used a year ago, which stabbed the stone spear from the ground. But he didn't think that these touch-shattering, extremely fragile wooden thorns could cause any kind of damage to people.

Is it the wrong posture and pronunciation just now? Or is it a problem with the wood? Since it's called silk wrapping, its function should probably be to entangle the enemy, or should I use those vine-like plants to try the effect?

Although he was extremely curious in his heart, at this moment, Yue Yu didn't have much time to think about it. After suppressing these thoughts for a moment, he almost couldn't wait, and took another book wrapped in a cyan animal skin next to him in his hand, and then turned directly to the last few pages.

The successful use of this silk entanglement spell made him look forward to these martial arts books even more. Since the meridians in one's own body can be completely adapted to the practice route of a secret method. Then in the rest of these books, there may not be other secret techniques that can be suitable for him to use-

It is precisely because of this thought that his current mood is a little impatient.

And the one he picked up just now is also an intermediate martial arts secret book, but the surname is the wind system, and the words 'Wind Slashing Sword' are also written on the cover.

- The bookshelf in front of Yue Yu is labeled with a wooden martial art. However, as one of the five elements, one of the less lethal castes. The wood-based martial arts and water-based martial arts in the world are the same, and they are very few in existence. Therefore, more than half of the more than 50 books on this shelf are the second series of wind and thunder. The so-called wind is Xun, thunder is shock, these two derived caste spiritual powers, both are the five elements of wood. It is not unreasonable for the people of the Yue family to put it together with the secret technique of the wood system.

However, this time Yue Yu did not do it easily, there was a reason why he first paid attention to this wind system martial arts secret book. In fact, he had been surprised by the Silk Entanglement Atlas even earlier. There are at least a quarter of the meridians that must be passed through by Namu's spiritual power, which completely coincides with the spiritual power of the Wind Blast.

Therefore, Yue Yu had a strange thought at that time, did this Wood Wind and Thunder Three Secret Methods all have similar practice routes, and were there any other commonalities?

- Undoubtedly, if he wanted to test his suspicion, he would have to find a few more secret methods that also belonged to these three castes.

And at this moment, among the several intermediate martial arts books in front of him, only this secret book of the Wind Slashing Sword, which was deliberately placed before the Silk Winding Spell, was the most likely to contain the existence of secret methods.

"Hey, you kid, you're really greedy!"

At the same time, the gray-haired and brown-shirted old man next to him also noticed Yue Yu's actions. He first looked helpless, and then subconsciously wanted to reach out to stop it. Yue Yu's dangerous move just now almost caused him to go into cardiac arrest. If the future hope of the clan in front of him was really ruined in front of him, he asked himself if he would never be able to bear this heavy sin.

However, just when his hand came into contact with Yue Yu's coat, the old man was stunned again and stopped his movements. He saw that the face of the young man in front of him was once again filled with a surprise similar to before. And what happened almost at the same time was that the vast cyan wind caste aura was once again converging in this direction.

As the gathered spiritual power became stronger and stronger, a powerful repulsion also came from his fingertips. The brown-shirted old man staggered back two steps in a hurry, and when he used all his strength to barely stand firm in front of this oppressive power. It was found that Yue Yu had already completed a mystical handprint at this moment, but this time, the wind spiritual power was not scattered like last time, but frantically concentrated on Yue Yu's palm. As a crescent-like cyan wind blade that was more than four feet long gradually took shape, the entire third floor seemed to be swept away by a violent wind. The mighty wind blew those scattered books everywhere, and even those heavy sandalwood bookshelves shook and fell.

At this time, the pupils of the old man in the brown shirt had also shrunk into a needle!
