Zhang Tianyou knew that if a corpse fell, it would take a while before the second one would fall.

When he came to Wu Sheng, he saw that Wu Sheng's clothes were really burned into a big hole, and Ye Xiaoluan and Shen Ziyu also saw them.

"It's sulfuric acid, a very high concentration of sulfuric acid." Ye Xiaoluan couldn't help but pull Zhang Tianyou back a few steps and said.

No wonder there was only a bone left in the corpse. It turned out that it was corroded by sulfuric acid, but why did sulfuric acid corrode the corpse? If the corpse wants to nourish any grievances, if it is corroded by sulfuric acid, it will probably have no nutrients. At most, it will increase the yin energy and resentment in this area.

"Tianyou, look at this below." Shen Ziyu squatted down and shone the flashlight under the cauldron, and suddenly said.

Zhang Tianyou looked in the direction she pointed at with a flashlight and saw that something seemed to be connected to the bottom of the cauldron. Because there was a huge stone under the cauldron, no matter how big a tree grew, it would not be possible to grow into the stone. There was a gap.

"Isn't this underground empty?" Wu Sheng also saw it and said to himself.

It is very likely that they had encountered a "blood pool" on the way to Thailand before, and there was a tomb below.

If this big cauldron really plays the role of "Gayin Pool" here, there must be something underneath it.

"Senior brother, it's important for us to hurry up. It's too late to burn this tree. As for whether there is anything underneath, let's not worry about it." Ye Xiaoluan knew Zhang Tianyou's temper and wanted to understand everything.

Look at this big tree for at least thousands of years or even longer. If there is really something under it, it is not a joke.

"Junior sister, since we are here, it's okay to leave. Don't worry, I will never take risks." Zhang Tianyou knew what the junior sister was thinking, and hurriedly whispered.

"Okay, if I find danger and let you leave, we will leave immediately." Ye Xiaoluan knew that not being able to force him too much. If he forced him too much, it would make him feel rebellious.

"Sure, certain." Zhang Tianyou was very happy to see the junior sister agreeing.

But how did you get down to the ground? There must be a cave entrance nearby, but after so long, the cave entrance may have been blocked long ago.

Just when he was in a dilemma, he suddenly heard a "boom" sound, which scared Zhang Tianyou. When he looked back, he saw Wu Sheng holding something next to the big tree.

Zhang Tianyou walked closer and saw that it was a bronze chain covered with copper rust. Originally, the copper chain was growing on the tree, but Wu Sheng shoveled it down again with an engineer shovel. Who knew that as soon as he tried his best, a hole collapsed in front of him, just a place not far from the big tree, which was more than ten meters.

At this time, they didn't care about the chain and walked quickly towards the collapsed place. They saw a big hole collapsed there, two or three meters wide and four or five meters long.

He looked down with his hands, five or six meters deep. He looked up at Lei Gang: "Brother Lei, have you brought the rope?"

"Take it." As he said that, he took out the rope and handed it to him. For the mercenaries, this is the necessary equipment to come out.

"That's good. Senior Brother Wu and I will go down and take a look. You are waiting on it." Zhang Tianyou took the rope and looked at the junior sister.

"Senior brother, I'll go with you." Ye Xiaoluan was worried and hurried over and said.

"Junior sister, my senior brother and I just go down and see what are you doing?" Zhang Tianyou smiled and said, "Don't worry, as long as there is a little danger, I will come up immediately."

"real?"

"Tsk, we couple for so long, how could I lie to you?" Zhang Tianyou said seriously.

"Okay, I won't go, let Ziyu follow."

Zhang Tianyou thought to himself, yes, I knew you would say this. Since she came out, she had asked Ziyu to follow her, and now she is almost her own shadow.

"Okay!" Zhang Tianyou agreed helplessly.

Ye Xiaoluan and Shen Ziyu looked at each other and laughed, just as the two had already agreed.

Zhang Tianyou tied the rope and then went down. Wu Sheng didn't want to go down, but Zhang Tianyou was the head teacher, so he didn't dare to ignore him. He finally went down with a bitter face.

Lei was just now thrown, so he was asked to guard it.

As soon as I got down, I felt like a cellar underground, because there was a semicircular hole inside, and they walked in one after another.

In theory, no one has come in here for so many years, so there should be no oxygen, but they found that there is sufficient oxygen underneath, but there is a fishy smell of soil.

Looking at the surrounding walls, the walls are full of traces of manual digging. It seems that this passage was dug out by hand. If this is the case, it should not have grown.

You should know that in ancient times, the tools were simple, and it was necessary to waste a lot of manpower and material resources when digging a passage several meters long.

Sure enough, after walking less than ten meters, they saw that the space inside began to expand; but suddenly, Zhang Tianyou stopped.

Because he saw that there were tree roots in front, some were tied to the ground, and some were attached to the wall.

He was pulled away by a vine just now, and he is still in fear now.

"Tiyu, you guys wait here first, I'll go over and take a look." Zhang Tianyou lowered his voice and said.

"You have to be careful!"

Zhang Tianyou responded and walked slowly over with the Juque sword. Just now when Shen Ziyu was pulled over by a vine, their swords just fell under the tree. Now they have already picked them up.

He was afraid that the tree roots below would be alive, so he first touched them with the Juque Sword, and felt that nothing was wrong, so he continued to move forward.

"The drilling force of this tree root is really big, and it drills through the stones." Wu Sheng looked at the tree roots full of caves and said to himself.

"You are blind. Have you not seen the roots of the tree grow in from the cracks?" Shen Ziyu said angrily for Zhang Tianyou.

Wu Sheng looked carefully and found that it was true.

At the same time, Zhang Tianyouyou had already entered, and Shen Ziyu was really worried, so he followed him slowly with the Mo Jian.

Wu Sheng also wanted to see what was inside, so he followed in.

By the way, they had already come to the tree. At this time, they saw Zhang Tianyou standing there in a daze. Shen Ziyu hurried over and held him and asked worriedly.

"Tianyou, what's wrong with you?"

"No, nothing, you, look there."

Shen Ziyu was stunned and looked at him, and saw a coffin-like thing leaning against the right side, but it was covered with soil and surrounded by tree roots, so it was hard to see clearly.

Shen Ziyu walked over, cut off several tree roots, and cleaned the soil on it. It was really a coffin. However, this was a bronze coffin. Because the underground moisture was too heavy, it was covered with copper rust.
