Several people returned to the huge house with the wooden boat, and soon found Xiao He's air canister.

The air tank was full of blood, Ding Sicheng didn't care much, and was about to carry it on his back, but was snatched by Poplar and carried it in his hand.

A few of them went back to the fork in the road where the hole had been dug and placed the blood-stained air tank there.

Only Jiang Peng was not sure, and he always carried his own air tank and was unwilling to put it down.

After that, a few people followed the path that Jiang Peng Ding Sicheng had walked, and walked back to the place where there were mechanisms on the walls on both sides, and Bai Yang asked everyone else to wait in place, and he went to look for the air tank alone.

Because to walk this way, you have to jump more than two meters and land firmly on the rough log that is a little shaky.

Although Tie Niu was able to easily jump more than two meters, he had never practiced light skills, and he had to land firmly on the round rough log, so as not to make the round rough wood shake a little to trigger the mechanism, but he was not sure at all.

In addition, the remaining distance is not far away, Tie Niu can only stop and wait for Baiyang to come back with Ding Sicheng and Jiang Peng.

Fortunately, it was not long before Poplar carried the air canister he had left in the room on his back, and leaped back along two round logs, and several of them returned the same way to the fork in the road where the hole was dug.

Poplar put down the air tank he was carrying and wanted to put it on Ding Sicheng's back.

The Iron Bull scrambled to carry the blood-stained air canister on his back.

Ding Sicheng knew that the two of them respected and loved themselves, so he didn't say much, and directly put the clean air tank on his back.

Poplar first put the eyepatch on the overhead lamp on his eyes, and was about to bend down into the hole, when Tie Niu stretched out his hand to hold him and said: "Every time you enter the tomb, you always walk in front of me, saying that you are careful and I am sloppy, and I am afraid that some mechanism will hurt me! But this big hole was obviously dug later, and there can be no mechanism in it, so let me walk in front!"

Bai Yang said: "You have an air tank on your back, and if you encounter an unexpected situation in front, it is inconvenient for you to even turn around, so I am still in front!"

"Then I'll put the air canister on your back!"

Iron Bull said as he unloaded the air canister from his back.

Bai Yang grabbed his hand and said, "You yourself admit that you don't hold your breath as long as me, why do you have to fight like this?"

As he spoke, he bent down again and burrowed into the ground.

Tie Niu was angry but helpless, so he had to follow Poplar into the burrow.

Jiang Peng praised: "Their brother and sister relationship is really good!"

Ding Sicheng nodded and smiled, and asked Jiang Peng, "How many does Master Jiang want to walk in?"

Jiang Peng smiled embarrassedly and said, "You guys are more capable, can you ...... I'm walking in the middle?"

"Then you go in third place!" Ding Sicheng said. waited for Jiang Peng to burrow into the ground before he followed in.

The cave was very spacious, and it sloped down with a large slope, so that several people could climb very quickly with air tanks on their backs.

The strange thing is that after climbing down for about twenty meters, the slope of the downward slope is getting steeper and steeper, and Tie Niu can't help but say: "Why does this hole go straight down, and it is getting steeper and steeper, isn't this going directly to the bottom of the sea?

Bai Yang didn't make a sound in front, but Ding Sicheng in the back said: "Have you ever played a small game when you were a child, that is, take a bottle and put it vertically into the water with the mouth of the bottle facing down?"

"Yes, I used to play like this when I was a child!" replied Iron Bull, suddenly understanding, "You mean, this hole is dug straight down to prevent the sea from rushing into the tomb?"

"It's very possible!" Ding Sicheng replied, "If there is a trench under the tomb, then as long as the hole is dug vertically into the trench, you can go out along the trench, and you don't have to worry about the sea water pouring into the tomb!"

"But how closed is that, is this tomb so closed?" said Iron Bull.

"Don't forget that there is a layer of circulation outside that wraps the tomb, so the closure should be sufficient!" replied Ding Sicheng.

"But the verticality is not enough! If you want the bottle mouth to not enter the water, it has to be absolutely vertical!"

"Yes, the verticality is not enough for the time being, so the back will definitely get steeper and steeper! Xiaobai, you should be careful in front, don't panic too much if you fall!" Ding Sicheng explained.

Poplar said yes in front.

Sure enough, I didn't climb far, and the slope became so steep that my hands and feet couldn't hold it at all, and Poplar had to shout: "I'm going to slide down, be careful!"

He then slid down the hole so fast that he could only hold his javelin straight in front of his head in case of danger ahead.

The hole got steeper and steeper, and the aspen slid faster and faster, until at last it turned vertically downward, and the whole body of the aspen fell straight down with his head and feet.

Fortunately, Poplar had many adventures, and he did not panic at this time, but he knew that he was about to fall into the sea, so he took a deep breath and went into his stomach.

He felt a pain in the top of his head, and it was as if he had crashed into a slimy solution, and it was so dark that he couldn't think.

He, of course, did not crash into the solution, but fell into the seawater.

It's just that the pressure in the depths of the sea is too great, and he falls straight down from a height, and this impact force is not something that ordinary people can withstand.

And before Poplar could wake up, he felt an undercurrent pushing his body and rushing out.

Poplar didn't know where he would be washed away, in fact, in the depths of the sea, no matter how great his ability was, he couldn't help it at all.

Instead, he felt as if his entire body was being squeezed by an invisible force from all directions, squeezing his chest and his brain cracking.

He barely managed to keep himself from being flooded until the speed of the undercurrent slowed down, and he gradually became a little conscious, so he raised his head and looked up and down, left and right.

Luckily, the special lamp above his head, and the blindfold that came with it, were not crushed by the tremendous pressure of the seabed.

Otherwise, even if his body could barely withstand such a heavy pressure, his eyes would have to be blind.

And as he turned his head, he could see the situation around him more or less clearly.

He found himself in a fairly wide cavern, long and narrow, and narrower at the back and wider at the front.

He knew in his heart that Ding Sicheng's speculation was correct.

It seems that this submarine tomb was not built on a flat seabed, but on a narrow trench.

It's just that there is a big wooden boat under the tomb, presumably this wooden boat is just above the trench. Over the years, the sediment gradually obscured the wooden boats and the surface of the trench, making the area around the tomb look very flat.

From this point of view, the person who dug this deep hole is not only very familiar with the interior of the tomb, but also with the terrain below the tomb.

This further proves Poplar's previous suspicion that the person who dug the deep hole must have been involved in the construction of the tomb, and was a key figure in the builders.

Poplar thought in his heart, and looked back at the narrow side of the trench.

In the depths of the sea, the water was actually quite muddy, but he could still faintly see that a little light was quickly rushing towards him.

He knew that it must be the Iron Bull, and he was already feeling a little deprived of oxygen now due to the weight of the seabed, so he waited for the Iron Bull to approach, so that he could take a breath through the Iron Bull's air tank.

But he didn't wait for the Iron Bull to get closer, and first felt a grown shadow cruising past him.

He immediately turned around, and saw a long, strange fish staring at him.

The strange fish was at least three meters long, with a pointed mouth, a slippery body, and two small protruding eyes on either side of its head, which seemed to be weighing him to be dangerous.

Poplar remembered the moray eel that came out of the mud and sand before, and the strange fish in front of him was very similar to the moray eel, but it was not the same.

Just thinking about what kind of strange fish this was, the fish suddenly twisted, and suddenly rushed to the poplar, opened a sharp mouth full of white teeth, and bit at the poplar.

Although Poplar was not shocked, he hurriedly turned around in the water and dodged, and the javelin in his hand struck at the long body of the strange fish.

He clearly felt that the javelin had hit the body of the strange fish, but in that instant, he felt that the strange fish was all over, and at the same time, there seemed to be an electric current transmitted along the javelin into his body.

Poplar never expected this situation to happen again, he couldn't control it at all, and he was so shocked that he couldn't stop spasming.

The strange fish turned around again and bit down on the poplar's neck.

Although Poplar was in a state of involuntaria, the strong desire to survive in his heart still made his waist strain, barely over the vital point of his neck.

Immediately after a pain in his shoulder, he was bitten on the shoulder by the strange fish.

More electricity flowed from the strange fish into Poplar's body, and Poplar's body spasmed and trembled more and more, and the javelin in his hand was lost somewhere.

He had never felt so uncomfortable, and every piece of skin and even every cell on his body seemed to be constantly torn and reassembled.

Then tear and reassemble.

He had originally eaten immortal medicine and golden python gallbladder, and his body's ability to resist pressure far exceeded that of ordinary people.

But under the powerful pressure of the bottom of the sea, under this inhuman torture, he finally couldn't hold it anymore and fell into a complete coma.

It's an electric eel—

It was his last bit of consciousness.
