Wu Song said with some excitement, his intuition told him that the green light was unusual.

The two climbed a high stone pillar and came to a few meters away from the top of the cave.

Wu Song's eyesight was astonishing, and he could see that the green light was emitted by a lichen that grew in the cracks of the rocks. After looking at it for a moment, he saw the clue.

The green light covers a radius of several meters, and seems to be arranged according to a certain pattern.

"I could see that it was a kind of text. ”

Yan Zhan said excitedly that when he was studying with Zhang Da in Tianyun County, he had studied an ancient book, and according to Zhang Da, that ancient book was left by one of the ancient races.

It took decades for the scholars of Tianyun County to decipher this script.

"Do you recognize this kind of writing?"

Wu Song was also excited, his instincts were not wrong, it seemed that this was indeed a clue.

"I think about it, I learned this kind of writing five years ago, and I can't remember it for a while. Well...... The opening sentence is, I ...... the Great Medicine Valley"

As soon as Yan Zhan said the first three words, Wu Song let out an exclamation.

The Great Medicine Valley, which was destroyed forty years ago, actually carved this text in this dark cave? This is really incredible.

Yan Zhan took some time to decipher the entire text.

To the effect that one of the disciples of the Great Medicine Valley was chased and killed and fled to this cave. The main medicine king of the Great Medicine Valley, Hua La, knew that Mu Xiu would be destroyed by the forest wind, and knew that the momentum of the Great Medicine Valley was too strong, and there must be many people who wanted to bring them down.

So Hua La secretly built this cave and arranged mechanisms in it. In the future, if someone wants to be unfavorable to the Great Medicine Valley, when the disciples are cornered, they can enter this cave to protect themselves.

It's a pity that the medical king Huala didn't expect that the enemy who was unfavorable to the Great Medicine Valley would be so powerful, and he razed the Great Medicine Valley overnight, and then chased and killed the descendants of the Great Medicine Valley in the entire Eastern Great Continent.

In the end, there was only one disciple of the Great Medicine Valley who escaped into the cave, and when he entered, he was already seriously injured and in danger.

Moreover, the enemy also entered the cave with him, and although he activated the mechanism, the enemy would definitely be able to get out of the trap after some time.

The disciple knew that he had reached the end of his rope and wanted to die with the enemy. But before he died, he couldn't bear to have no successor to the Great Medicine Valley, so he hid all the knowledge in his chest in this cave, and the way to find them was in the text on the top of the cave.

In addition, the method of opening the mechanism in this cave is also hidden there.

"As long as we find what that disciple left behind, then we can get out of here. ”

Yan Zhan said eagerly.

"Yes, but what's the way to find those things?"

Wu Song touched his chin and fell into deep thought.

There were so many words on the top of the cave, and there was no mention of directions or anything like that, so they couldn't find it.

Yan Zhan was also thinking, but he was also at an impasse like Wu Song.

"Wait a minute, you see, isn't there something strange about the pattern of these words? It looks a little bit like a diagram of the meridians of the human body?"

Wu Song said suddenly, he looked at the words that emitted green light, and a smile gradually appeared on his face. The words are made up of several lines, each of which is nothing on its own, but when taken together, it looks like a map of the meridians of the human body.

If the center of this text is the starting point, then the line of words on the left is the Shaoyang Sutra. But what does that mean?"

Yan Zhan wondered, seeing that this text implied a meridian map of the human body, what was the connection between finding what the disciples of the Great Medicine Valley had left?

"Wait a minute, there's a small line over there, 'If you want to practice this skill, you must be under the age of eighteen' What does this mean?"

Yan Zhan was puzzled, and suddenly saw a line of small words in the lower left corner, because it was too small, I didn't see it just now.

"I think this meridian diagram should be the route of the Yuan Force, as long as you follow the above and run the Yuan Force, you should be able to understand the clues to find out what the disciples of the Great Medicine Valley have left.

I'm over eighteen, what about you?"

Wu Song said thoughtfully.

"I'm just eighteen years old this year, so I'll practice. ”

Yan Zhan said, with both joy and some anxiety in his heart. The disciples of this Great Medicine Valley spent so much effort to leave this piece of exercise on the top of the cave, which must be a superior exercise.

But it's not necessarily, if this is a trap, then I'm afraid there will be damage after he cultivates.

But now is not the time to hesitate, the two of them have reached a dead end, and now the only way out is to cultivate this mysterious exercise.

Yan Zhan came to the ground, sat cross-legged, and prepared to cultivate.

"Okay, I'll report the route of the Yuan Force, and you can run the Yuan Force according to it. First of all, the qi goes less yang. ”

Wu Song stayed on the stone pillar and reported the Yuan Force operation diagram to Yan Zhan.

The two cooperated with each other and began to cultivate.

Half an hour later, Wu Song finished reporting all the Yuan Force operation diagrams.

After Yan Zhan's Yuan Force ran according to the map for a week, he suddenly felt that many acupoints such as his left shoulder, right leg, and abdomen were opened, and his whole body Yuan Force suddenly had an extremely comfortable feeling.

At this time, he suddenly realized that those meridian movement charts composed of words had a total of eighteen running routes, and each route was a way of attacking.

He tried to follow one of the routes to run the Yuan Force, and found that a liquid suddenly appeared on the palms of his hands, emitting a foul smell.

Running in another way, I found that there was a smell that contained a strange fragrance all over my body.

Yan Zhan had learned some things about pills before, and at this time, looking at the liquids and smells he produced, some of them looked like poisons.

Combined with the fact that this was a peerless study left by the disciples of the Great Medicine Valley, he firmly believed in his own views even more.

This exercise should allow the monk to turn his own Yuan Force into poison.

Yan Zhan was not mistaken, this exercise was called the Ten Thousand Poisons Sutra, and it was created by Wang Huala, the chief doctor of the Great Medicine Valley.

Since ancient times, healers have recognized the sense of heaven and man. There is an invisible connection between the human body and all things in heaven and earth, and this connection exists in all aspects, and it is natural that there is also in the medical Tao.

According to this principle, Hua La created the Ten Thousand Poisons Sutra. With the monk's own meridians as the soil and the Yuan Force as the seeds, all kinds of poisons are produced in the body.

The poison produced by the Ten Thousand Poisons Sutra is highly toxic and can be adjusted at any time according to the monk's own wishes. It can be said that anyone who has been poisoned by the Ten Thousand Poisons Sutra is basically dead and alive.

The eighteen routes left by the disciples of the Great Medicine Valley on the top of the cave were just for the monks to get started. Once these eighteen routes have been refined, the monk has mastered the operation method of the Ten Thousand Poison Sutras, and then he can find new routes to produce new poisons on his own.

There are many meridians in the human body, and there are thousands of running routes, and there are thousands of poisons that can be produced, so this exercise is named the Ten Thousand Poisons Sutra.

"How's it going?"

Wu Song saw that Yan Zhan had not reacted for a long time, and asked on the stone pillar.

"Wait a little longer. ”

Yan Zhan said.

The disciples of the Great Medicine Valley left the Ten Thousand Poisons Sutra on the top of the cave and wrote eighteen routes. He also said that this was a clue to obtain what he left behind, could it be that after the latecomers practiced this exercise, they would create these eighteen kinds of poisons, and then they would be able to discover something?

Thinking of this, Yan Zhan immediately ran the Ten Thousand Poison Sutra and created the same poison according to the eighteen routes.

Wu Song saw Yan Zhan's concentrated exercises, thinking that he had not yet refined the exercises on the top of the cave, so he raised his head again and looked at the words on the top of the cave, wanting to see if there was anything missing.

Looking at it this way, it really made him see something.

Previously, they had seen that the text on the roof of the cave was arranged in eighteen thin lines, which together were the meridian movement of the human body.

Just now, Wu Song inadvertently looked at this diagram upside down, and found that it was also a diagram of meridian movement, but it was completely different from the one he was looking at.

Why is it that there are two diagrams of the meridians when you look at it upside down? Could it be that one of the diagrams is fake and the other diagram is real?

Which diagram is fake? Is it the one you are looking at? What will happen if you practice a fake diagram?

Wu Song didn't dare to think any further, and hurriedly shouted to Yan Zhan, "Yan Zhan, stop! ”

At the same time, Yan Zhan had also finished cultivating the eighteen kinds of poisons. All the poison coalesced and seeped into the ground from under his feet.

I heard the sound of a mechanism rattling, and a stone door opened on the stone wall to the west, and a bright light shot into the cave.

"It's done!"

Yan Zhan shouted excitedly. He was right, these eighteen poisons were indeed the key to unlocking the mechanism.

"Opened the trap?"

Wu Song thought suspiciously, then there is no problem with saying that the picture you are looking at is okay, but what is the matter with the picture you are looking at upside down?

"Wu Song, come down, let's get out of here. ”

Yan Zhan shouted below.

Wu Songshi climbed down from the pillar, intending to ask Yan Zhan what was going on with that technique and how he opened the mechanism.

Yan Zhan stood more than a meter away, waited for Wu Song to come down, waved his hand to him, and said with a smile, "Thank you, Wu Song." ”

"You're welcome, anyway, if I help you, I'm helping me, we're on a rope now..."

Halfway through Wu Song's speech, he suddenly felt a sharp pain in his chest, dizziness, and his body weakened, and he fell to the ground.

"Grasshopper on a rope? You're wrong, and now we're going our separate ways. I'm going to leave here and walk on the bright road, and you're going to die here. ”

Yan Zhan's tone was cold, and he was like the two of them just now. In other words, the current Yan Zhan is the Yan Zhan that Wu Song is familiar with, with no one in his eyes, cruel and murderous.

"You...... Right...... ...... to me What did you do?"

Wu Song felt as if he was in a boiling oil pot, and there was a sharp pain all over his body, every inch of his skin.

"You have been poisoned by my unique sect, and you will soon die in agony. This is the technique found on the top of the cave, and after refining, you can convert your own yuan power into poison. You are fortunate to be the first person to die in my hands after my success, this is fate, hahaha!

Enjoy yourself here, hahaha!"

Yan Zhan laughed smugly and left the cave. The exit to the stone wall was closed, and the cave was plunged into darkness again.
