A faint fragrance of books came into Chen Xuan who stepped into the fourth floor. The faint fragrance of books came to him, and the smell of sandalwood fragrance. The scene on the fourth floor was completely beyond Chen Xuan's imagination. It was not the rows of bookshelves he thought, with all kinds of books placed on it, but the books were completely embedded on the wall.

Hundreds of books were completely embedded on the wall and could not be removed at all. Chen Xuan really couldn't imagine how this would be. And some of them could not see the books at all, with only a faint phantom, looming.

"Are these books not for people to watch?" Chen Xuan said to himself.

"Wrong, I'm for you to show it!" A faint voice suddenly came from the front.

Chen Xuan was stunned by the sudden sound, and then asked, "Please give me some advice!"

"It's very simple. Enter your soul power and enter the book on the wall to get the knowledge you want. However, this is also a very soul power consumption. The amount of knowledge you can get depends on how long your soul power can withstand it!" The voice of the speech just now sounded again, and then returned to calm. Chen Xuan asked a few times without answering again.

Chen Xuan, who was standing there, quickly understood what it meant, which was to input soul power into these books and absorb knowledge from it. This should also be a very consuming thing, otherwise he would not have made any comments to remind him just now, and a spiritual consciousness differentiated from Chen Xuan's soul sea.

The soul power condensed into a rope shape and floated towards a very old book on the wall. At this time, Chen Xuan didn't know that the book here was what he needed, so he could only try it one by one. His spiritual sense was like Chen Xuan's eyes, and it was instantly absorbed by this ancient book. The soul power did not listen to his orders at all, and felt that the soul power was swallowed.

Suddenly, a virtual picture appeared in Chen Xuan's soul sea. This is the picture in ancient books, slowly presented in Chen Xuan's soul sea. This is actually a book of fighting experience, which teaches how to be suitable for battle and what measures should be taken when the strength is not as strong as the other party.

Chen Xuan's soul power was disappearing rapidly, and the pictures in the sea of ​​soul began to blur slowly. Chen Xuan felt that the book was absorbing his soul power. Chen Xuan had no hesitation and instantly cut off the connection with the book. At this time, the pictures in the sea of ​​soul also disappeared.

Standing there, Chen Xuan felt dizzy, his head was heavy, and he shook his head, and then absorbed some energy from the soul stone. Only then did he feel clearer and replenished the soul power he had lost just now.

"The speed of these books absorbing soul power is too terrifying. After two breaths, the soul power is almost emptied. Moreover, I have only watched about half of it, and I have not even seen the important part. It seems that the people who come in can only choose once, and it depends on the opportunity. Once they choose what is useless to them, wouldn't it be a waste of time? Not everyone is like themselves, with soul stones to restore their soul power!"

The consumption of soul power is not spiritual stones, and elixirs can recover, unlike the loss of elixirs. As long as there are a large amount of elixirs, they can recover instantly, but the soul power cannot be used, so they can only cultivate slowly. This is what Chen Xuan guessed. One person can only choose one book at a time, and his soul power is already strong enough, not enough to erode one book.

After the soul power was restored, Chen Xuan chose a book here. The soul power condensed into a rope and drilled into the book. The same picture appeared again. It was a book about the techniques of refining weapons. When he was halfway through the viewing, Chen Xuan took the initiative to cut off the contact and repaired his soul sea with the soul stone again.

Books were filtered out by Chen Xuan, and Chen Xuan actually felt that his soul power had been greatly improved here. Even the soul-dividing method he obtained could begin to separate the two soul powers and not disperse for a long time.

After more than a dozen books passed, Chen Xuan's face became ugly. Although there was unlimited repair of the soul stone, it was also a huge test for Chen Xuan. His face was pale and his eyes were dull. Chen Xuan looked at dozens of books on the wall, and his legs shook and he took a step back.

"I can only take risks. I have no time left. Generally, disciples who arrive here can only choose one book, but I have been delayed for so long. I must speed up!" Chen Xuan made another decision.

"laugh!"

Two soul powers came out of Chen Xuan's soul sea at the same time, floating towards two of the few dozen books in front of him. Chen Xuan risked his life to use the soul division method, and the two soul powers floated out of his soul sea.

Countless pictures were like movies, constantly flipping through Chen Xuan's soul. Chen Xuan's mind was completely silent. All the irrelevant filters were filtered, but there was still no answer he wanted. Chen Xuan decisively cut off the contact.

After breathing, Chen Xuan condensed into two soul powers and spread them out again. Two more books were injected into Chen Xuan's soul power. The picture appeared in Chen Xuan's soul sea again. At this moment, an arc suddenly drew across the corner of Chen Xuan's mouth.

"It's you, I finally found you!"

Chen Xuan looked at the pages of the book that he kept flipping through his soul and finally saw what he wanted.

"The Story of the Kun Beast!"

There are countless types of small Kunming beasts recorded above, as many as Fanxing. Chen Xuan gave up another one and focused on watching this book. The energy of the soul stone flowed continuously into his soul sea in order to meet Chen Xuan's needs.

Countless insects that Chen Xuan had never seen appeared in front of him, but there was no such black spots as black as the size of a needle that Chen Xuan saw on Dantang Mountain, and it also absorbed the essence of the spiritual medicine. The pages slowly disappeared in front of Chen Xuan.

Chen Xuan carefully distinguished each type, for fear of missing a detail, so he made a comparison. This required strong soul power to support it. Not only did it require soul power to maintain the operation of this ancient book, but it also required to extract soul power and distinguish whether there was something he needed in it.

Chen Xuan suddenly did it, and did not stand again, his eyes closed and his legs sat cross-legged on the ground. The book was very thick, with a thousand pages. Each page represented a type of creature. All Chen Xuan needed to do was to find out the thousand pages and find out the culprit in order to find a way to cure it.

Sweat flowed from the forehead first, and the clothes behind were wet. Although this was not a battle, it was better than a battle. This was a game of soul power. The consumption of soul power was endlessly consumed. Chen Xuan finally read more than half of the book, and he had not finished reading it, and he also absorbed a lot of knowledge.

The pages of the book were quickly flipping through. The little golden man, whose soul condensed in Chen Xuan, stood in his own sea of ​​souls, his eyes shining brightly, and he focused on the pages of the book that were flipping through his nose.

Suddenly, a cocoon pupa-shaped thing attracted Chen Xuan. It was not this cocoon pupa, but there were many black spots next to the cocoon pupa that Chen Xuan had seen. Countless small black spots crawled out of the cocoon pupa.

"Spiritual Eat Gu!"

Three eye-catching big words appeared on the top of the page. Chen Xuan's eyes instantly saw these three words. Then there were some boys written underneath, and his eyes condensed into thin lines and looked at the top of these boys.

The Spirit-eating Gu, a third-level monster, does not have any powerful attack power, but it is a nightmare for all practitioners. As long as you are involved in this kind of thing, you will be unable to get rid of it. Unless you have strong strength to completely kill him, otherwise he will think of a parasite, parasitizing in your body, constantly absorbing the spiritual energy on your body. If you practice three points, one point will be absorbed by this Spirit-eating Gu.

Chen Xuan's scalp was a little numb, why was it so difficult? He raised his eyes and continued to look at it. The following began to write about how to restrain it. This is what Chen Xuan needed.

Although the Spirit-Eating Gu is very annoying, there is no way. Just find his main pupa, refine it, and then summon all these pupas back. However, it is difficult to find where the main pupas are hidden. This is also a headache for many practitioners. Here I pass on the experience I have gained to future generations, so that no one will be eroded by the [Spirit-Eating Gu] again.

Chen Xuan paused for a while, continued to look down, and then saw again how to find the main pupa.

As long as there is a place where the pupa appears, it will definitely be accompanied by the main pupa. However, the main use is cunning and cannot be discovered at all. I have learned the experience I have obtained through many experiments and passed on to future generations. The best way is to pass on spiritual energy, because the food of [Spiritual Food Gu] is spiritual energy. As long as a large amount of spiritual energy is arranged in one place, it will not dissipate the spiritual energy, so that it may lead the main pupa and capture it at all.

Another method is to follow the route of the pupa. Although this method is feasible, I advise future generations not to try it. If you are not careful, your body will be eroded by this [Spiritual Eating Gu], because once you encounter a large number of [Spiritual Eating Gu], you can't even worry about it yourself, so the best way is to catch the main pupa, which is the best strategy.

Chen Xuan finished reading all the boys and immediately cut off his connection with the book. Then he sat on the ground, still silent in the world just now, his mind full of the scene just now.

After two breaths, Chen Xuan, who was sitting on the ground, suddenly ejected and started to do it. "No, time is coming, mine is coming, I don't want to be sent out!" Chen Xuan immediately walked towards the stairs on the same third floor, but this time there was no obstacle to the light curtain, and Chen Xuan easily passed through it.

Just after Chen Xuan left, a faint light appeared on the uneven wall, and then a faint phantom appeared.

"Interesting, some people can persist in reading more than twenty books here. It seems that except for someone who read more than ten thousand years ago, no one can persist in more than three books in a row. This kid is interesting!" After saying that, the phantom turned into a book and sank it on the wall.
Chapter completed!
