Chu Yun gradually reasoned about the whole body of the rock demon, and tapped the position of the heart with his finger, Lin Xiyan also nodded in agreement, Chu Yun's analysis was not wrong, the location of the heart and the dantian should be the most critical place.

After putting away the simulated image, Chu Yun took Lin Xiyan and Nangong Ling and walked into the depths, and gradually smelled a smell of blood, and it was fishy. Nangong Ling and Lin Xiyan were girls after all, and they immediately frowned, covering their mouths and noses with one hand.

Because he was afraid of getting lost, Chu Yun was also very careful, and took the little hands of the two people and walked forward, and suddenly felt that the soft little hands became a little slippery, turned around and let go of his hands and took a look, and found that the palms of the two girls were immediately fragrant sweat, and the little hands were already pinched out of cold sweat.

Chu Yun immediately knew that these two people were nervous, after all, this was the body of a huge monster and it was pitch black in front of him, and the flames in Lin Xiyan's palm could not shine far away.

I can't bear it myself, let alone these two girls.

"It's okay, you don't have to be afraid, it's safe with me" Chu Yun smiled slightly and wanted to make the two of them relax, high tension is a fatal existence for monks, and the perception around them will have a serious impact, so that the reaction to emergencies will be very slow.

After groping forward for nearly half an hour, he finally saw a faint fluorescent flicker in a cave in front of him, which was particularly conspicuous compared to other caves, and Chu Yun recognized that it was the light emitted by the beast core, colorful and colorful, as if there was some strange treasure born in the cave.

Seeing the light, the three of them gradually relaxed a lot, and walked over quickly with the attitude of thinking that they saw people, standing at the entrance of the cave, Chu Yun immediately smelled more bloody, and a few steps inside, he saw dead bodies everywhere, and the tragic situation was incomparable.

Originally, he turned around and wanted to stop Lin Xiyan and Nangong Ling from coming in, but these two people followed in, and the moment they saw it, they vomited directly.

Ye Feng took out the half-question sword, looking at the injuries as if they were corroded from above, everyone was covered with countless wounds, cruel and bloody, with hideous faces as if they were dead, their bodies were extremely twisted, some killed each other, some seemed to have been bitten to death by something, and there were at least fifty corpses in a strange shape.

Chu Yun squatted down and observed the strange appearance of these corpses, for himself, these deaths were not unusual, he had seen too much, what made him strange was to find that these were all martial souls that were withdrawn before death, what kind of strength was so terrifying.

Could it be that there is an incalculable existence in this rock demon body? Chu Yun stood up and looked into the depths, so he could only walk in and take a look.

As soon as he took a step, Chu Yun felt that since his Hongmeng Dao Book had begun to turn the pages, he turned out a blank page, and he knew that such a scene also appeared when he saw Nangong Ling's martial spirit.

Thinking back to the situation where the martial soul at the entrance of the cave vibrates, is this the only situation that can only be achieved when encountering a peerless martial soul?

Could it be that there is really a peerless martial soul here, and it became excited, it seems that he has really come to the right place, at this time, Chu Yun does not care about the danger in front of him, he must break through the peerless martial soul, which is rare in the world.

"You two follow me closely, take out your mysterious weapons and be on guard, since there are dead people, there may be unknown dangers inside"

Chu Yun instructed a few times, and the half-asked sword was held horizontally in his hand, and his expression became serious.

Slowly passing through the pile of dead people, I found that since the entrance of the cave was a very empty place, the flames of the surrounding black forest could not illuminate the surrounding walls at all.

"According to our inferred route, our current position should be in the position of the ribs," Lin Xiyan said as he looked at the dark surroundings. Chu Yun nodded in agreement, and took out the beast core that he had just picked up in the middle of the corpse, there were more than two hundred beast cores, and the two of them finally knew Chu Yun's intentions, and just now they said that Chu Yun was greedy for small gains.

Each beast core was thrown out by Chu Yun, only to see the lights of various colors around the stars light up, and with the gradual increase of the beast core, it also brightened up, and the environment was completely presented.

This is a space of the same general size as Linhai City, looking at the space of three people is breathtaking, if there is no light to illuminate the walk in, I am afraid that I will not be able to walk out of the whole life, the space is surrounded by some broken houses, staggering, completely without the appearance of the past, in the middle is a large pavilion.

It is a thirteen-storey pavilion, three people slowly looked around, the pavilion building is very peculiar, there is a door in each of the eight directions, now the façade is collapsing, see that it is empty inside, and the walls around it are also some places to fall off and can't see the words on it.

The doors and windows are full of holes, broken like an ant's nest, and there are white silks that I don't know what they are hanging straight in such a windless environment, looking like a gray-haired person with his head bowed.

Chu Yun took a deep breath and walked up from a staircase with courage, slowly brushed aside the white silk with his hand, and took a look at the environment inside.

On the door frame hangs the three words of Wanshulou.

Looking at the paper slag on the ground, and there were some dense words on the yellowed fragments, Chu Yun picked up a few pieces of paper, and there was still mucus underneath.

After a few glances, the words on it should be martial arts or exercises, and turned around and walked beside the two people.

"This should be their library building, it says Wanshulou, and these few words Xiyan, you can see if it's martial arts."

Lin Xiyan took it and looked at it a few times, nodded and confirmed that it was a martial arts scroll. Chu Yun looked back, since it was a library building, why didn't the people outside die here, but outside.

"Brother Chu, why is it windy here?" asked Nangong Ling.

As soon as Chu Yun and Lin Xiyan came out, the two of them hurriedly looked around, but there was nothing in the surrounding space under the light of the beast core, Nangong Ling pointed up at the white vertical silk, and Chu Yun looked at it and it was really swinging.

"Be careful, there may be some mysterious beasts in here," Lin Xiyan reminded on the side.

But Chu Yun looked at Bai Si and suddenly laughed, this is really a great opportunity, it can be said to be the first opportunity on the land of Shenzhou.

"It's a bookworm" Chu Yun walked over and touched Bai Si, no wonder he always felt strange when he came in and saw Bai Si.

Lin Xiyan looked at Bai Si looking at the slime on a few pieces of paper, and Lin Xiyan immediately thought of this, there are bookworms in the Refining Sect.

Bookworm is a kind of mysterious beast that is self-generated in the scroll that has been stored for a long time, because the reason for the formation is very harsh, it must be a quiet environment without a trace of disturbance, different levels of exercises, martial arts, the influence of the surrounding environment, time factors, etc., so the probability of formation is very low.

Even if a bookworm is formed, it is very difficult for a bookworm to feed, because if it makes a living by eating scroll martial arts, a bookworm may have to lose the entire collection of books in a sect and may not be able to survive.

But if it succeeds, it will be a million profits that are equivalent to having a living library, and the bookworm can evolve new martial arts and exercises from the original martial arts, such abilities are not comparable to monks, and the martial arts evolved by the bookworm are all flawless.

Bookworms can also help monks improve their comprehension of exercises and martial arts. For example, it may take ten years for a complex cultivator to practice, but with a bookworm, three years is enough.

Adult bookworms can also fight with monks, and the martial arts and exercises they eat will also become capital, which can help monks use any martial arts, because bookworms will remember the contents of the scroll in their minds after eating the scroll.

In today's Shenzhou land, the one who is still raising bookworms is a sect in the Divine Temple, and it is also because of the wealth that he can afford to raise it, and even the Refining Weapon Sect does not have such strength.

Seeing that Bai Si can spit out such white silk, it can be concluded that this bookworm should be an adult, and there is no need to eat martial arts all day long, and you can eat a little once in a while.

Seeing this, the three people thought that the monk outside had died after being attacked by a bookworm, which was the only way to explain it now, but Chu Yun contradicted it again, there was no need for the bookworm to devour the martial soul. However, they were able to come here safely, and the bugs were already full, and they didn't have any appetite in the face.

Chu Yun looked at the white silk swaying on it and concluded that the bookworm should be on top. "Rich and dangerous, let's go up and take a look, it should be safe after making trouble for so long"

Slowly picked up the white silk and walked into the Wanshulou, looking at the rows of countless bookshelves as high as ten zhang, all of which were covered with traces of gnawing and white silk.

"How many exercises are these cheats," Nangong Ling looked at and was also amazed.

"Many, at least our Refining Sect can't compare, compared to this one, the light of the fireflies is better than Haoyue" Lin Xiyan is not destroying his prestige. It was this layer that was enough to surprise them, Chu Yun took a moment to see if there was a complete exercise, and after looking for a long time, it was all fragments.

"This little guy is still very dedicated, since he eats so cleanly"

Chu Yun couldn't help but vomit

"Don't you want to think about it, I'm afraid that the little guy has become a big guy after many years, can his appetite not increase?" Lin Xiyan stood aside and said.

The three of them walked up slowly, and with each floor they felt the pressure of a mysterious beast coming towards them, and it became clearer and clearer, and hairs stood up on their skin.

"Feel the breath, it should have reached the Heavenly Demon Realm, right?" Lin Xiyan said excitedly.

Although Lin Xiyan walks around all the year round, his personality is relatively quiet, he basically doesn't go out of the room when he has nothing to do, and he likes to read books, especially classics, so he has never seen a mysterious beast like a bookworm, and this time he is really happy.

"It feels like an atavism, let's go up and have a look."

Chu Yun led the way up, the wooden planks of the pavilion creaked, and when he came to the twelfth floor, he saw a little fluorescence floating in the air, floating in that fixed space.
