It would be difficult for Chu Yun to retreat now. In addition to allowing him to move forward, it would be too difficult to turn around unless he uses the technique of refining muscles and bones.

However, he had been climbing the rat hole for half an hour, and it was unreasonable to go back like this. Although he didn't know how long it would take to climb now, Chu Yun was still ready to continue walking.

Chu Yun was shocked by Xiaobai's ability. He had been crawling in the hole for half an hour. It had only dug two hours of holes and could dig out so many underground passages like mazes. This ability was enough to make any human being ashamed.

Next, Chu Yun climbed two more incense sticks, and Xiaobai finally took the initiative to make a squeaking sound. Chu Yun was delighted that he might be going to the place.

Sure enough, after one man and one rat advanced more than a hundred meters, a light came from the front, making Chu Yun overjoyed.

But after a moment, Chu Yun began to wonder again. He was basically climbing down the road along the way, and the terrain I just saw on the ground was plains and several high mountains. Logically speaking, this place should be deep underground, how could there be light?

With doubt, Chu Yun crawled to the end, and after his head was stretched out from the hole, the scene inside completely came into Chu Yun's eyes.

This is indeed a closed underground secret room, but now it is not completely closed, and a passage has been dug out by Xiaobai.

It has to be said that this secret room is very solid, about three meters in size, which is definitely a large secret room. Moreover, this secret room should be made of a very high-strength stone of very golden stone. This kind of stone is comparable to the refined steel. At this thickness, even if it is a treasure soldier, it is difficult to dig it open.

But Xiaobai's claws were really too amazing. The stone was dug up like paper in front of it.

On the wall opposite Chu Yun, there is a thick stone door, and it is unknown where it leads to. However, Chu Yun estimated that according to the idea of ​​the person who originally designed this secret room, people should be walking in that door, and there may even be a passage outside the door. As for whether there will be hidden weapons in the passage, it is not Chu Yun’s concern.

Who made Xiaobai the one who was uncommon? As Chu Yun who turned from the rat path, he also didn't have to consider hidden weapons or other mechanisms.

As for the light Chu Yun saw just now, it was because at the top of this secret room, there were three night pearls the size of fists inlaid in triangular positions.

This is a real night pearl. Each one is amazingly bright, and three are together, illuminating the entire secret room like daytime.

"This is definitely a diluted treasure!" Chu Yun looked at the three night pearls. Even if he did not obtain other treasures, he could make a lot of money just by relying on these three night pearls.

Such rare treasures are no less valuable than precious elixirs and weapons.

Chu Yun finally moved his gaze from the three night pearls and began to carefully observe the layout of the secret room.

At this moment, Xiaobai had already landed on the ground of the secret room, squeaking, as if urging Chu Yun to go down quickly.

Chu Yun didn't dare to act rashly. Do you know if there are any hidden weapons below? The power of these things will generally not weaken with time, and Chu Yun didn't want to take risks.

After he carefully observed and found that there was indeed no hidden weapon in this place, he rushed out of the cave entrance and landed on the ground of the secret room.

The secret room has a large space, but there are not many things inside, which looks a bit empty.

In front of him was the stone gate, and nothing was placed on this side. On his left side, there were a row of bookshelf, and books were neatly placed on it, which seemed very intact. However, Chu Yun still didn't know whether these books were ordinary books or martial arts secrets.

On the right side of Chu Yun, there was a shelf with some porcelain bottles, jade bottles or boxes on it. Chu Yun had extraordinary eyesight and saw those porcelain bottles at a glance, with the names of elixirs marked on the jade bottles.

"It seems that the successor of Xiao Li Fei Dao can also refine elixirs, or these elixirs were collected by him." Chu Yun estimated that the latter was more likely because Chu Yun had never heard of the successor of that generation of Xiao Li Fei Dao who was proficient in alchemy.

On the back of Chu Yun, there were about a dozen large boxes, which were tightly sealed and could not tell what was inside.

Chu Yun is undoubtedly the bookshelves that most concerned about. If there is really a secret book of Li Xiao Li flying knife in this secret room, the most likely place to exist is the bookshelves.

He walked over quickly, carefully reached his hand in front of a book, and was about to pull it out.

But he had just pulled out the book with great force, but the whole book completely fell apart and fell to the ground, turning into debris.

"Damn! How many years have it been?" Chu Yun exclaimed. Although paper pages generally decay quickly, they usually store them in such a closed underground secret room for a long time.

The book is so unbearable now, which means it has been at least five or six hundred years.

Of course, if this book is a martial arts secret book, then its year should be longer. After all, the martial arts secret book itself carries the will of the editor. With the blessing of this will, its decay becomes very slow. Moreover, the higher the level of martial arts, the stronger the will it carries, and it is less likely to be broken.

If there is really a secret book on Xiao Li’s flying knife here, it would probably not be broken even if it is stored for more than a thousand years.

Chu Yun pulled out the next book again, but the book also broke.

However, before the book was broken, Chu Yun saw the name on the cover of the book: Dragonfly Three Copy Water.

Damn! You're cheating?

Dragonfly Three-Shunting Water was Li Xunhuan's famous light skills. Although his reputation cannot be compared with his flying sword skills, it is also the most famous martial arts under the flying sword. It was also known as the highest light skills in the martial arts world at that time.

Chu Yun guessed that even if the light skills of Dragonfly Sanjue were not peerless martial arts, it was at least a top-level light skills.

If this is a real Dragonfly Three Water Copying Secret, it would never be broken so easily. The only explanation is that it is a fake secret book, just like the secret book of the flashing finger magic that I saw in the illusion array outside Gongzhou City.

This may also be a test for the people who left this secret room to the later ones, deliberately leaving some fake secrets.

But no matter how smart this person was at that time, he probably wouldn't have thought that these fake secrets would reveal their true self as time goes by.

Chu Yun was more confident at this time. Since there were fake Dragonfly Three-Copying Secret Books here, there should be real ones, right? Otherwise, what is the point of leaving this secret room on the other party?

Next, Chu Yun quickly took off the books on the bookshelf one by one. As the books were broken, Chu Yun gradually became nervous.

What if there is really no secret recipe for Xiao Li flying knife here? This not only means that he has a waste of time, but the most important thing will also affect his next layout.

Chu Yun twitched another book, and just as he was ready to break the book again, the book was actually intact and he held it in his hand.

"System prompt: I detected that the host has the top light skills of Dragonfly Sanzhushui. Do you learn it?"

"study!"

Chu Yun naturally would not be stupid and not learn. This is the top light skill. The third top martial arts that Chu Yun has learned so far is also the first top light skill.

Although Chu Yun practiced Yunlong San's appearance technique in the past was quite powerful, it was still very different from the top light skills, especially the Dragonfly Sanctuary. However, Li Tanhua's famous light skills were considered to be a top-notch light skills even among the top light skills.

If you practice this Dragonfly Three Copy Water to the realm of returning to nature, you will probably be able to escape safely even if you encounter a master at the peak of the Three Flower Realm. To be continued.
