Since he was carrying an oxygen cylinder this time, Zhu Yu was not in a hurry, he dived slowly, observing the creatures around him while diving.

Originally, in Zhu Yu's thoughts, there was no light in this underground space, and even if there was an ecosystem, I was afraid that it would be very fragile, and there were few living things.

But what he saw at this time was very different from what he had imagined.

When he first arrived in this space, the movement startled the small animals in the vicinity and moved away.

When the water waves calmed down, Zhu Yu found that the small animals nearby had resumed their original leisurely swimming methods, swimming slowly in this space.

And Zhu Yu also found that most of the creatures in this area have almost degenerated their eyesight, and some of the eyes even have no children's holes, and the eyes are white.

However, all the creatures here look different from the outside world, and if a biologist comes, I am afraid that they will be amazed by the existence of these creatures!

However, Zhu Yu didn't want to disturb these creatures, he was just curious about these creatures, and after seeing them, he dived down.

He wanted to see if there were any more sacrificial vessels underwater, as well as the rest of the boy's body.

Although the energy in Zhu Yu's body is relatively sufficient now, he knows very well that there are not many things in this world that contain energy—at least much less than those gold.

If you get one such thing, you will have one less. I don't know when I run out of energy in my body.

At that time, although it can be supplemented by the cultivation method, to be honest, that method is too slow!

It's better to have these things in your hands!

Putting away his curiosity about these creatures, Zhu Yu slowly dived underwater.

The further down, the more creatures there are, Zhu Yu thought to himself that after waiting for a while, when he got to the bottom of the water and caught something, he would simply find a bottle, catch something and go out, and raise it or give it to Joanna.

The further down you go, the more creatures there are, and the plants get bigger and bigger, some of them fluttering with the current, like kelp, and some of them are as long as big tufts of hair, which is a little scary to look at.

There are also some reasons like coral, colorful and beautiful, but Zhu Yu was a little surprised, how could there be such a beautiful creature in this underwater lightless environment?

He carefully avoided the hair-like and multicolored coral-like creatures, and finally reached the "ground" of the underwater space.

There is a thick layer of sediment here, and the entire underground space is like a lucky bag, with a small upper and lower bottom, and a flat space at the bottom.

Of course, this is not an enclosed space, but there is an outlet, which is located on the wall of the cave on one side, in the upper two-thirds. That is, if the water level in this space is less than two-thirds, then the water cannot get out.

The whole space seems to be larger than a football field, and after Zhu Yu observed it, he had a feeling.

It's kind of like some kind of ornamental fish tank.

And myself, and the creatures in it, are like things in a fish tank for people to see.

This ridiculous thought flashed away, and Zhu Yu began to activate the Heavenly Eye and scan it downward.

Sure enough, there's a lot of stuff down there.

In the mud and sand under his feet, only half a meter deep, there was a broken copper stone axe. There are also delicate patterns on it, and it is obvious that this should also be a sacrificial vessel.

Zhu Yu dug out the stone axe and felt the little energy contained in it—almost equivalent to the energy of 100,000 ice jade.

Putting it away, Zhu Yu continued to scan.

One thing was dug up one by one - there were bronze, silver, and gold, and to Zhu Yu's surprise, the one that contained the most energy turned out to be a stone tool - this was a stone spear.

When it was dug up, the wooden handle of the stone spear had decayed, and only one spear head remained.

But just this spearhead, the energy contained in it exceeds all the previous gains.

Zhu Yutian's eyes swept over and saw that the year of this stone spear had been more than three thousand years, and it was a genuine antique, so it could not be said that it should be a product of the Stone Age.

Even after all these years, the stone spear was still very sharp, and although its energy was not as strong as the scepters that had been dug up in the forest, it contained much more energy than the golden figurines.

However, the energy contained in this spearhead is mostly killing power, and after absorbing it, Zhu Yu doesn't know if it will affect his character.

Putting away the spearhead, Zhu Yu continued to search.

A golden shield, a golden helmet, a silver belt, and a broken bronze basin......

Zhu Yu is like picking mushrooms on the grassland, picking up the harvest here.

Suddenly, he seemed to sense something, and turned his head to look up behind him.

I saw a dark shadow slowly swimming by—it seemed to be a big fish.

When the eye of the sky opened, it was indeed a big fish, quite ancient, and I didn't know if it was a lungfish.

Zhu Yu felt a little ashamed of the biology teacher, this kind of creature has forgotten everything.

The big fish was more than a meter long, and it didn't seem to be interested in Zhu Yu, or it didn't find Zhu Yu, so it swam away.

Zhu Yu felt that it was better to be careful, his movements slowed down, but the feeling was radiating. He didn't want to be attacked in this environment.

If you really want to be attacked here, then there is really no one to save yourself.

Zhu Yu picked up some more things, and by this time he had almost reached the center of the underground space.

The things here are densely packed, and there are seven or eight things in the size of only a dozen square meters.

Unlike the gold objects that were once dug up in the ground, there are really all kinds of things here, and there are even some wooden statues, but they have basically rotted under the water, and only two of them have become gloomy wood, and Zhu Yu put them away.

Half an hour later, Zhu Yu finished collecting this piece of things, and after a rough calculation, he almost put away nearly a hundred things.

In terms of value, although it is not as good as the pit of gold in the forest before, it is almost tens of millions of dollars.

In this space, there are also a lot of human bones, as well as animal bones.

Zhu Yu had a rough spell in his mind, at least dozens of people were sacrificed, and there were many more animal bones.

The harvest was not small, but there was no bone that contained the same attribute energy as the little boy's vertebrae.

Zhu Yu set his eyes on the underwater plant.

These plants grow in the middle of the entire underwater space, taking up a space about the size of a basketball court.

The growth is dense and varied.

Looking at the plants of different shapes, Zhu Yu was a little reluctant to step forward.

But think about it, the next one has come down, if you don't go over, then this trip will not be successful.

Zhu Yu took the first step, and the next steps were much firmer.

He's still more careful.

Although there was no danger before, no one could guarantee that there would be no danger in these plants.

His eyes swept over and saw that there were still many creatures in the plants, and he was not sure if these animals were dangerous.

In short, be careful.

Zhu Yu walked into the bushes step by step, and he found that when he passed by, some of these plants were close and some were far away, as if they had feelings.

But then he didn't have time to take care of these plants, in the eyes of heaven, the roots of these plants, in the mud and sand, there were a large number of sacrificial vessels!

The energy in these sacrificial vessels is abundant, and the rhizomes of these plants wrap around these sacrificial vessels, as if absorbing that energy.

Not far away, there was an arm bone, and the green energy in it was exactly the same as the energy in the spine that he had picked up earlier!

Zhu Yu immediately went over and dug out the arm bone first.

Along with it, there is also a soft root of a plant, as if it is alive, wrapped around that arm bone, reluctant to give up.

It wasn't until Zhu Yu put away all the arm bones that the whisker searched around "stunned", and finally hung down again.

Zhu Yu could feel that these plants were not like the plants outside, their rhizomes, and even the branches and leaves might have abnormal activity.

So when he used a shovel to dig up the sacrificial vessels under the mud and sand, he was extremely careful not to touch the roots of those plants.

Despite this, when he squatted down to dig a thigh bone, a slender thing behind him, like a thin branch of a certain plant, was slowly swimming over, and then opened his mouth wide and bit down on the back of Zhu Yu's neck!

Zhu Yu's hand suddenly stretched out and pinched back, and he grabbed this thing that resembled a water snake!

grabbed this thing's neck, and the other party's body immediately rolled towards his arm!

And the power of this winding is very large, which makes Zhu Yu feel that it is difficult to grasp!

Zhu Yu became competitive, and immediately increased the strength at hand!

With his current strength, bricks can be kneaded into powder in his hands.

But the skin of this "water snake" is extremely tough, even if he has pinched the snake to death, the skin of this thing has not been damaged in the slightest!

But the flesh and bones in it have been crumbled into mud.

That's a good material!

Zhu Yu put this thing into the space, and the eye of the sky swept over and found that there were many such water snakes among the plants!

Some are preying on fish, some are lurking, some are slowly crawling on plants, and some are swimming towards Zhu Yu!

Zhu Yu didn't panic, after he had determined the combat power of these water snakes, he understood that if he hid, he would lose a large number of treasures underwater.

With Tianyan as a cheat, he is not afraid of these guys at all - the first water snake that swam over was accurately choked by his neck, and it was already pinched to death before the other party could be entangled.

Article 2, Article 3......

These water snakes did not act together, which gave Zhu Yu ample opportunity.

After pinching to death fourteen water snakes, Zhu Yu stopped, and then, when the eye of the sky passed, he found no dangerous things, and he continued to squat down and began to "pick up treasures".

One by one, the sediment was dug up by him, but the harvest became richer and richer.

The things that Zhu Yu deliberately looked for also appeared one by one-

ribs, finger bones, metacarpal bones, pelvic bones......

One by one, one by one, in the end, Zhu Yu felt that he could almost put together a human figure.

It's just a head.

Zhu Yu skillfully dodged those huge plants, and then came to the front of a giant "coral".

Passing through the sky, I saw that the root of this "coral" was wrapped in a skull.

The skull exudes a powerful energy, which is being absorbed by this "coral" little by little.

Needless to say, this skull should be the boy's head.

To get this skull, you have to dig the roots of the plant.

Zhu Yu was a little worried.

But after sensing it, the energy contained in this skull is several times greater than the sum of all the energy in the entire other bones!

Much higher than the energy in that silver cross!

It's worth the gamble!

Zhu Yu took out the shovel from the space and dug it up!

Fortunately, although this plant looks like coral, it is not really coral, and it is not even as hard as the trees outside.

After all, it grows in water, and although it is flexible, it has more water, and its roots are relatively easy to shovel.

Just halfway through the shovel, Zhu Yu felt that something was wrong!

The top part of the plant is starting to writhe!

Could it be that these energies have created a monster?

Zhu Yu was ruthless, and the shovel in his hand was directly replaced with a saw, quickly cutting this huge plant from the roots!

The plant's twist became even more violent, and many creatures on it began to flee from the plant, some went to other plants, and some began to run down, attacking Zhu Yu!

Zhu Yu quickly dug out the skull with a shovel and put it into the space, then he raised his head, waved the shovel, and slapped the attacking small animals one by one!

Even underwater, when the shovel is swung, it still carries patches of blood of various colors.

Soon, the smell of water and blood attracted more predators!

And Zhu Yu had quietly turned to the other direction of the plant bush at this time, seeing that there was no danger around, and continued to dig up the sacrificial vessels under the sediment.

Although the inlet is at the bottom of the lake, Zhu Yu guessed that the next time he came over, he didn't know when, instead of waiting for the next time, it was better to catch as much as he could this time.

Estimating the amount of oxygen available, Zhu Yu sped up the speed of digging.

And at this time, in those creatures, the killing was over, and three or four large fish more than two meters long became the final victors.

However, they were not satisfied, and seemed to feel that there was still too little food, and even tore at each other in order to eat a mouthful, showing the fangs in their large mouths.

At this moment, a huge creature suddenly rushed straight from above, and with a mouth, it bit a big fish, shook it vigorously, and then swallowed it!

The rest of the big fish immediately scattered and quickly disappeared without a trace!

Zhu Yu also felt the change in the water flow above, and immediately opened the heavenly eye to look at it!

He saw a tail that was more than a meter long and nearly two meters wide!

And the speed of the thing was so fast that it was out of the range that the eye could see!

Zhu Yu was suddenly taken aback!

He immediately put away his plan to continue digging and prepared to float!

Anyway, the main goal has been salvaged, and it is conservatively estimated that the income of this trip will exceed 100 million.

Then hurry up and get out!

Safety is paramount!

He also deliberately went around the direction of the tail he had seen earlier, and started to float up from the other side!

Let's hope we can get away from that big guy!
