The crack was about half a meter wide, and it looked like it was about half a meter deep. But there are green vines underneath, and it's impossible to determine how deep it is.

There were a large number of green vines gushing out from there before, so Wu Song estimated that the depth of the crack in the ground should not be so shallow.

Wu Song's mind turned, and he used the little remaining Yuan Force to launch the Birth Moon Dafa to probe the depth of the crack in the ground.

Detection Zhihu, as Wu Song expected, the crack in the ground is definitely more than half a meter shallow.

Below the crack in the ground, extending half a meter further, there is a huge underground space.

According to Wu Song's estimate, that space was a mile in circumference.

When he fought with the Autumn Thorn Beast before, Wu Song estimated that there was a lot of space underground. Otherwise, how could the Autumn Thorn Beast possibly hide its massive body underneath.

After knowing that there was a huge space under the crack in the ground, Wu Song immediately thought of a way to get out.

At this moment, Huaxing Li Tian and Zhang Liu both moved to the vicinity of the ground crack, and this was the best time.

"Yan Zhan! your life will not be long, and you will be arrested before you tie your hands!" Wu Song shouted.

"Joke! Now that your life is not long, it is you who should be arrested. Yan Zhan sneered.

"Idiot! That day we were in the cave of the Great Medicine Valley, and by chance, you learned the Peerless Ten Thousand Poisons Sutra of the Great Medicine Valley. You think you've got a treasure, but do you know that the Ten Thousand Poisons Sutra has a fatal point?"

Wu Song said loudly.

"What's fatal?" Yan Zhan hesitated, his tone wasn't as tough as before.

After Yan Zhan obtained the Ten Thousand Poisons Sutra, he really thought that he had obtained the treasure as Wu Song said, and spent a lot of energy to practice.

At first, there was nothing, but as his cultivation deepened, Yan Zhan began to feel that something was wrong. Every time he used the Ten Thousand Poisons Sutra, a random acupoint would appear on Yan Zhan's body, and he would feel pain.

At first, he thought that his practice method was wrong, and he only needed to adjust it in the future to avoid this kind of problem, so he didn't take it seriously. But over time, the problem has not only not been resolved, but has intensified.

Two months ago, after every time he used the Ten Thousand Poison Sutra, the painful acupoints on Yan Zhan's body were not one, but increased to two.

The pain in the two acupoints at the same time, as if being shot by a sharp arrow, made Yan Zhan miserable.

At this time, Yan Zhan realized that there was a big problem with him. If not addressed in time, then there is a high chance that it will be life-threatening.

So, Yan Zhan visited famous doctors all over the place, hoping to cure his illness.

But he searched all the doctors in Tianyun County, and everyone couldn't do anything. Those doctors don't want to prescribe medicine, they can't even figure out what is going on with Yan Zhan's body.

This is because Yan Zhan's illness is caused by the Ten Thousand Poisons Sutra, and the Ten Thousand Poisons Sutra is the mastery of the Great Medicine Valley, those ordinary doctors, without the reference of the Ten Thousand Poisons Sutra, where can they see its secret?

Because his illness is getting worse day by day, Yan Zhan doesn't think about tea and dinner, and it has become a heart disease.

Now that Wu Song said this, Yan Zhan was immediately moved. After all, nothing in the world is more important than one's own life.

"The Ten Thousand Poisons Sutra is the mastery of the Great Medicine Valley, but it is an evil skill, although a cultivator can create ten thousand poisons after cultivation, but every time he creates a poison, a little poison will accumulate in the body.

The more poison you make, the more damage you will suffer.

In the end, there will be a poison attack, life is better than death, and death will be in excruciating pain. You haven't been using the Ten Thousand Poison Sutra for a long time now, and it will be much easier to treat. ”

Wu Song said.

"Is that really the case?" Yan Zhanhu wondered. He and Wu Song are mortal enemies, and the two have fought several times, each time he wants to put Wu Song to death. In such a relationship, he didn't understand why Wu Song was willing to help him.

Wu Song saw Yan Zhan's confusion and said, "I will help you, naturally there is a condition, that is, let us go now." As you can see, my two friends are no match for you, and if they continue to fight, they will inevitably die.

And the two of us are evenly matched, so it's hard for me to rescue them.

So, I'll tell you the way to cure the Ten Thousand Poisons Sutra, and you let us go. How?"

Yan Zhan looked at the four people who were still fighting next to him, the situation was clearer at this time, Hua Xing and Li Tian were under the attack of Zhang Lao Er and Liu Lao San, left and right, and they were in danger, and they had no power to fight back at all.

Indeed, as Wu Song said, if they continue to fight, the two of them may die here.

"Okay, I promise you. Yan Zhan said.

"Then you first ask your assistants to return to your side. Then I'll tell you how to treat it. Wu Song said.

"I asked my men to retreat, what should I do if you run away?" Yan Zhan said.

"Don't worry, the terrain here is open, we just really run, you can catch up at any time, you don't have to worry. Wu Song said.

Indeed, as Wu Song said, the place where they are now is a valley, and there is flat land within a radius of several miles, and there are no woods except for the sparse grass.

In this way, no matter where Wu Song and the three of them ran, Yan Zhan and the others could see it and immediately catch up.

"Okay, Zhang Laoer, Liu Laosan, you come back. After thinking about it for a moment, Yan Zhan said.

Zhang Liu and the others stopped attacking Hua Xing and Li Tian and returned to Yan Zhan's side.

Hua Xing and Li Tian stood in place, and the place where they were at this time was only one meter away from the crack in the ground.

"Okay, I've called them all back as you said, now it's time for you to tell me how to treat them, right?" Yan Zhan said.

"The method of treatment is also a superior exercise, and it cannot be easily listened to by others. I've written it on a piece of paper, and now I'll give it to you. Wu Song said and took out a piece of paper folded in half from his arms and threw it to Yan Zhan.

Then Wu Song jumped to the side at the same time that the paper flew out.

Yan Zhan's heart was on that piece of paper, and he didn't care about Wu Song. He flew up and grabbed the paper.

On the other side, Wu Song jumped to Hua Xing and Li Tian and said, "Let's go." ”

The three of them came to the crack in the ground, and Wu Song used the Great Law of Birth Moon, condensed the Yuan Force on the surface within a radius of twenty meters, and shattered the ground at the crack in the ground.

Sure enough, as Wu Song expected, a huge underground space appeared under the crack in the ground.

The three of them leapt in and disappeared into the cracks.

And at the same time, an angry roar erupted, "No!! Wu Song, you bastard, I'm going to kill you!"

After Yan Zhan got the piece of paper, he couldn't wait to open it and look at it, and found that there was nothing on it, just a blank piece of paper, and he was deceived.

Yan Zhan immediately flew up, followed by Wu Song and them into the cracks in the ground, followed by Zhang Laoer and Liu Laosan.

After Wu Song and the three of them entered the cracks in the ground, their bodies fell rapidly, and after falling three meters, some natural stone pillars appeared around the three of them.

Wu Song stretched out his hand and pressed on a stone pillar, his body stopped falling, and then he rolled over in the air and landed firmly on the ground.

Over there, Hua Xing and Li Tian also showed their own magic powers and landed on the ground.

The three of them looked around, only to see that they were in an underground cave, this cave was not a little deep, Wu Song and they now landed on a raised cliff, they looked down the cliff, only to see that it was dark below, and they couldn't see anything, like a bottomless abyss.

The three of them secretly said that it was dangerous, if they didn't stop the trend of falling in time just now, then if the three of them fell into the bottomless abyss, they would really die and have no place to be buried.

"Let's go! Wu Song said.

As soon as Wu Song's words fell, he heard an angry voice sound above his head, "Wu Song! You dare to lie to me!

Yan Zhan stood at the top of a stone pillar next to him, looking at Wu Song and the three of them condescendingly. After speaking, there was a transparent whip in his hand, and the whip was like a poisonous snake, twisting his body and attacking Wu Song and them.

"Be careful!" Wu Song said, he knew that it was Yan Zhan's weapon, the Heavenly Silkworm Cold Silk, which was very powerful.

Hua Xing used his Yuan Li and planned to jump in front of Yan Zhan and attack him. Unexpectedly, Wu Song was one step ahead of him, and rushed to the front.

The Heavenly Silkworm Cold Silk took Wu Song's chest directly, Wu Song launched the Divine Blade without a shadow, his palms flew over, and he swirled around with the help of the palm wind and the Heavenly Silkworm Cold Silk.

In the last battle of the Three Spirits, Wu Song had already seen the power of this silk thread. The silkworm silk is extremely flexible, as thin as a human hair, but it can cut through steel.

The human body is just like soft mud in front of it, and it is vulnerable.

Therefore, Wu Song always kept a distance from the Heavenly Silkworm Hansi and did not let it touch his body.

Under the pressure of Wu Song's palm wind, the Heavenly Silkworm Hansi spread out into a canopy, and surrounded him at a distance of half a meter from Wu Song.

Yan Zhan used his Yuan Force and desperately drove the Heavenly Silkworm Hansi to attack Wu Song.

The two sides fell into a stalemate for a while, and no one could help the other.

And Zhang Laoer and Liu Laosan were lagging behind, and they were coming at this time, and Wu Song had already seen them more than a mile away

Hua Xing said loudly, "Brother Wu, I'm here to help you!"

Wu Song hurriedly said, "Don't avoid it, you guys go quickly, I'll drag them alone." ”

"Brother Wu, how can that be? Wouldn't it be more dangerous for you to stay alone. Hua Xing said.

"Don't worry! I have my own way of getting out, and if you stay, it will distract me! Hurry up!" Wu Song said.

Hua Xing and Li Tian glanced at each other, hesitated for a moment, and Hua Xing said, "Then Brother Wu, we will wait for you in front." ”

After saying that, the two of them used their tricks and fled.

In the impression of the two, Wu Song has outstanding resourcefulness and advanced cultivation, and he can always break out of another world where it is impossible.

Before, whenever they encountered a crisis, Wu Songxiang came up with a solution.

Therefore, this time they still chose to believe Wu Song and do what he said.

In fact, Wu Song had a plan to get out, but he just used words to reassure Hua Xing and the others.

This underground cave has a hundred turns and thousands of turns, and there are many bends and curves, plus the light here is dim, Hua Xing and Li Tian disappeared from everyone's sight in the blink of an eye.

Zhang Laoer and Liu Laosan wanted to chase after them, but they estimated that they couldn't catch up, so they gave up.

Yan Zhan and Wu Song were still in a stalemate, and when they saw that Zhang and Liu had arrived, they smiled cruelly, "The surname is Wu! Today is your death! Zhang Lao Er and Liu Lao San, kill him!"
