"See if you die!" Tang Yu looked at the head of the water monster again, and with a "boom", he hit the head of the water monster directly without dragging the mud and water.

This time, the water monster bounced out again, popped up dozens of meters away, and then "Peng" fell into the water. After waiting for a while, it never surfaced again.

Tang Yu knew that it was either fainting or dead. They no longer look at the shore, but dive directly into the water.

The water temperature of the lake in the mountains is still quite cold, but Tang Yu has true qi to protect his body, and he can operate his own oxygen group, so he can dive underwater for a while, of course, not too long.

Tang Yu suddenly dived into the water. I saw the entrance to the cave, and the inside of the hole was pitch black, and I couldn't see anything from the outside. Tang Yu's perspective was useless here, which made Tang Yu wonder. It seems that there is indeed some ulterior secret in it. Otherwise, the water monster has been squatting on it, and it seems that it hasn't left for many years.

"Do you really want to go in?" Tang Yu asked the medical saint with his mind again.

"Nonsense, it's all down, if you don't go in, I won't let you go!" said the doctor speechlessly.

"you!" Tang Yu snorted coldly. Looking at the underwater hole, to be honest, Tang Yu was stunned in his heart, such a black rumbling thing, you dare to go in. Even if there is a water snake or something in it, it can scare people to death. And the water and grass next to it are dense, which is even more eerie and terrifying.

"Hurry up and get down!" the healer urged again.

"Your sister's, it's not your life!" Tang Yu said speechlessly. I was stunned for a moment, thinking, let's go in, in fact, I also want to know what is inside.

Tang Yu then touched the hole with his hand and slowly slid in, but he still couldn't see what the bottom was. Tang Yu had no choice but to move on. The walls of the cave are covered with stones, mud, water and grass, and you can't see anything at all.

"I'll it!" At this time, the information of the medical saint suddenly came to his mind, which made Tang Yu very surprised, Tang Yu hurriedly asked, "The medical saint, what's wrong?"

"What's wrong, there's something wrong, why is this so much like a thief hole!" said the Doctor Saint.

"What do you mean?" Tang Yu didn't understand, and asked in surprise.

"Thief hole! it was dug by someone!" said the Doctor Saint again. "Do the tomb robbers know? If they want to rob the tomb, they have to dig a hole before they can enter the tomb!"

"What! rob the cave!" Tang Yu was surprised to be shocked, "Doctor Saint, you are not mistaken? You are not a tomb robber." How can you see it at a glance?"

"I ...... Actually, I was a tomb robber when I was young!" said the Doctor Saint.

"Rub!" Tang Yu was speechless, he didn't expect that the medical saint was actually a tomb robber before. "No wonder your tomb was stolen, you deserve it. It's called retribution!"

"Retribution to your mother!" the medical saint also scolded angrily. "Keep going, don't talk nonsense, it's possible that there is still an ancient tomb at the bottom of the lake below!"

If someone else scolded him, then Tang Yu would have made him pay a painful price, but Tang Yu couldn't say anything about the medical saint's scolding, after all, no matter what she said, she was also her own elder, and she was considered a white-haired elder. But hearing that it was an ancient tomb, Tang Yu's heart felt cold again, the ancient tomb, isn't there a lot of organs? Tang Yu stopped talking nonsense and continued to move forward. After swimming for a few more minutes, Tang Yu estimated that he had walked dozens of meters, but he still couldn't see the bottom.

"I think we'd better go back, it doesn't look like there's a bottom at all. Tang Yu said speechlessly.

"What do you know, haven't you heard of another village? I'm sure you'll be able to reach it after a little while. "The medical saint is another teaching.

Tang Yu stopped talking, thinking that he had come here, and if he didn't find out, it would be unpleasant. So I moved forward. After walking for more than two minutes, Tang Yu couldn't help but be startled, because something seemed to be shining under the hole in front of him.

"You didn't bring anyone else down, did you?" and at this time, the words of the medical saint with some surprise and even a slight chill came from his mind.

"I, just myself, who else will there be besides me?" Tang Yu said speechlessly.

"But, why is there still a person in the back!" At this time, the medical saint suddenly said.

"What? are you talking nonsense, it's my shadow, right? Wait......" Tang Yu's hair stood up, because the shadow was clearly below, and Tang Yutong looked through it, and sure enough, he saw a shadow behind him, and it was exactly the same as a person. Tang Yu was stunned and frightened. How could there be a figure following! Could it be someone above who was worried about himself and deliberately followed? But this possibility is very small, although Xia Shihan and the others can swim, but they can't swim for so long, you know, from the entrance of the cave to now Tang Yu has been swimming for almost ten minutes, although the swimming is not fast, but these ten minutes can swim a lot of distance, not to mention fifty or sixty meters. No ordinary person has been able to do it for so long. And he doesn't shout himself either.

"Doctor Sage, you, do you see what it is?" Tang Yu asked in fear. Although he is not timid, but in this situation, anyone would probably be scared. In the underwater cave, a figure suddenly ran out and followed him.

"Made, even I can't see clearly!" said the Doctor Saint in amazement. "It's a person!" suddenly the healer shouted.

"Ahh It seems that there is also a long blade in his hand. Tang Yu can't reflexively go over now, which means that he is like a trapped beast now.

"What now, is this the so-called Bloodlight Calamity!" Tang Yu suddenly thought of the Bloodlight Calamity, because now he couldn't move at all, and that monster actually had a long blade, just like an ancient warrior, and like a ghost.

"Hit him with his feet with real qi!" said the doctor at this time.

"I wiped it! I forgot!" Tang Yu was so nervous that he actually forgot about it, even if he couldn't turn around, he could still attack the other party with his true qi.

Seeing that guy suddenly rushing over, Tang Yu's true qi instantly gathered on the soles of his feet again, watching that guy suddenly attack, Tang Yu instantly blasted out with "Peng". In order to defeat this monster at once, Tang Yu used the strongest true qi, if he couldn't kill him this time, the consequences would be unimaginable.

"Puff puff!" At this time, because of the powerful effect of true qi, in the narrow passage, the water surface swelled strongly, and Tang Yu and the Soul Doctor Saint were staring at that shadow to see if Tang Yu could beat this guy to death. If you don't die, maybe it's Tang Yu's death.

But what surprised Tang Yu was that when the true qi mass hit that guy, that guy directly scattered and disappeared!

"Wow, it's a phantom!" Tang Yu said in surprise.

"Sure enough!" said the medical saint coldly at this time. "I remember, this is a mechanism in the ancient tomb, a projection to scare tomb robbers!"

"Shenma!" Tang Yu was shocked. "And this thing, then why didn't you say it earlier! The old man was scared like this!" Tang Yu thought about it, what the medical saint said should be right, think about it, you are swimming in this dark passage, and suddenly, a person suddenly appeared behind you, followed you, and poked you with a long blade, you have to be scared to death. The ancients were really smart, they could do this, what was it made of. Tang Yu thought that he would have to study it for a while. Then he asked the Doctor, "Doctor, have you ever seen this thing?"

"Well, yes, I encountered it once when I was robbing tombs in my early years, and there were eight guys with me at that time, and I was scared to death of six, but fortunately I found out in time that something was wrong!" said the medical saint.

"-" Scared to death six, although it is a bit exaggerated, but Tang Yu is a believer.
