It is not difficult to enter the body of a creature and find out the structure inside.

No matter how special the stomach and lungs are, they will follow the concept of internal organs, as long as they perceive it, the two of them can know where it exists.

When calculating and perceiving, the space in which the four people were located was swirling for a while, accompanied by extremely dull sounds.

"It's bottoming out."

Xu Zhi and Qian Tong glanced at each other, and the body of the hydra was obviously rolled several times by the bottoming into the undersea passage, and it was still bumping against the stone wall under the sea.

"Based on the time and the speed at which the Hydra descended, we are now at least six thousand meters deep in water."

Qian Tong grabbed the wall of the esophagus with one hand, and grabbed Yan Jinbai, who was holding his breath, with the other hand to analyze.

"This is the depth of the death of the person."

After a little calculation, Xu Zhi, who was holding Gu Yuxi, couldn't help but scold.

In this deep water, Xu Zhi had no doubt that the internal qi he had opened would be pressed back into his body in an instant, and the strong pressure of the seawater would shatter his heart.

Once dead, he will eventually be flattened into a piece of jerky, which will then crumble into all sorts of minced meat and bone scraps.

This is not a place where he can adapt to survive in the master stage, only a body refiner like Tuo Guhong, or veteran grandmasters and great grandmasters have the ability to move freely in this environment.

Compared to their bodies, the body of the eight-headed hydra was thick and terrifying.

Meters of oil and skin hold the body in place, and it is supported by strong bones.

For Hydra, this depth is also not a suitable deep-sea space for survival.

The soft organs in various places firmly blocked the gaps in the mouth and nostrils, and fused into stubborn iron, and the body was almost flattened.

If they are in the normal form of a hydra, the confluence of their esophagus will be magnified at least ten times, or even more.

This compression makes the Hydra's body harder than alloy, and it can also allow its body to withstand the high pressure of this deep water.

The yellow, rancid, sour air was constantly compressed, condensed into acid and dripped down.

In the distance, the stomach finally stopped moving, and with the deeper and farther the sea eye current, this hydra, which was so powerful that Tuo Guhong was extremely helpless, finally entered the stage of death.

Except for the muffled sound of the outside world touching the underwater reef from time to time, all that was left in this space was the faint breathing sound of everyone.

I used to think that the skin and flesh of the hydra were too smooth and firm, but at this time, Xu Zhi hoped that this kind of oily and thick would be more violent, at least to withstand the bumps in the underwater passage.

Pierced anywhere in the body, whether it is the high-pressure water flow and high-pressure environment that rushes in instantly, or the Hydra stuck and unable to move, these extreme situations can make them follow the Hydra to bury quickly.

"How likely are we to escape?" Qian Tong said in a low voice with a pale face.

"How can there be a 1 in 1,000 chance of escaping easily, and that's how I came when I fell into the sea when I encountered the ruins."

Xu Zhi smiled, as a person who had experience in escaping from the deep sea, his words gave Qian Tong a little comfort.

Being in such a hostile environment, even a good word will not make people fall into complete despair.

"Don't say one in a thousand, it's one in ten thousand, as long as there is a little chance."

As everyone knows, Xu Zhi at this time is also with despair in his heart.

In this environment, there is not much difference between his abilities and Qian Tong's.

The concept of 1,000 meters under the sea and 6,000 meters of escape were completely different.

The former he can adapt to the environment in the sea, the latter he can't accept this extreme pressure at all, everything depends on this dead hydra to support the boat.

Whether it was the ability of the internal qi cultivation system or the ability of the magic cultivation system, it was not enough for him to escape safely.

His biggest characteristic is that he can carry, recover, and run, but in this place, there is no room for these three abilities to be used.

Perhaps the fifth-order magical shelter of the Life Department could come in handy, but that was far from what he could get his hands on right now.

"It has four stomachs, six hearts, and the left and right lungs are here, and there seems to be a lot of air stored in it, and I can feel the flow of gas oppression."

Qian Tong's Great Compassion Sword gestured for a while before carefully stabbing it from its iron-hard internal organs.

The compressed organs were squeezed very tightly, and when he stirred it with his long sword, the air in the punctured alveoli sprayed out.

When the sword was drawn, only a small amount of foul-smelling blood spurted out, and the place where it was pierced was directly pressed, and there was no longer a gap.

The air quality stored in the body of the hydra is extremely poor, toxic, strong pungent odor, less oxygen and more carbon dioxide, making it difficult to breathe directly, and it can be maintained by means of skin filtered breathing.

Xu Zhi ran the Hanzhang Closed Qigong and licked the blood of the hydra, which was so sour that it was bitter and numb, and there was a faint smell of sulfuric acid and rust.

This is a very peculiar kind of blood, and if you take more of it, you will be poisoned to death.

Even he could feel the poisoning factor, let alone a normal cultivator.

"Strongly acidic, highly toxic, useless."

In addition to looking for air and space, the two are also looking for everything that can be used in the body of the hydra.

If there are some special benefits that can be obtained, it may also help them a little.

It's never too late to cram, but this time it didn't give them a chance.

After searching for a long time, the busy and fruitless two finally found a space and began to follow Yan Jinbai and Gu Yuxi into the stage of hibernation.

If they can only do this, wait quietly in the body of the hydra, even if it is to slowly meet death.

Just like sleeping, if you hold your breath for a long time, you will wake up, and after you wake up, you will fall into the cycle of holding your breath.

Xu Zhi didn't know how long this time lasted.

Maybe three days, maybe five days, maybe seven days.

It's as if every moment is waiting for death, and time passes extremely painfully.

Holding your breath is not an easy task.

It's no different from a hunger strike, the beginning is hard, and the further you go, the harder it is to hold your breath.

The environment outside the body is different, and the situation inside the body is constantly changing.

From being trapped in apnea for more than ten hours, slowly entering seven or eight hours, then to five or six hours, and then to three or four hours.

Not only Xu Zhi, but even Qian Tong was unbearable, not to mention the other two cultivation and qi holding techniques with slightly lower levels.

For Yan Jinbai and Gu Yuxi, this painful experience can almost be remembered for a lifetime.

Hovering on the brink of death all the time.

Because of the high speed of movement under the sea, it was difficult for Xu Zhi, who had always been well stocked, to enter the natural state, not only did they have to endure breathing difficulties, but hunger was also accompanying them, and they had to swallow some oil and other parts of the hydra's internal organs to alleviate the situation.

A look of despair flashed across their faces from time to time.

But looking at the calm and calm Xu Zhi, and Qian Tong, who practiced the death exercise method "Hanzhang Closed Qigong" with a smirk on his face, they were mixed with a little hope in their despair.

There are also colleagues around to help.

Xu Zhi is in charge of eating, Qian Tong is in charge of air circulation, and each other is still struggling to survive.

After all, he is not alone in his breath, and he has not reached the point of going crazy.

Until one day, they began to notice that the space inside the Hydra was rapidly expanding.

This is not the swelling of the body caused by the decomposition of the corpse, but the continuous decrease in water pressure, and the compressed body of the hydra naturally rebounds into a state of relaxation.

Xu stood up violently.

Not only was it floating, but he could feel that the Hydra was drifting much faster than before, and the currents surging at the bottom of the ocean had been dispersed.

As long as it is not 6,000 meters under the sea, they can float to the deep sea channel of 2,000 meters, they still have the possibility of escaping.

A violent crash was heard from time to time, and the body of the hydra collided wildly in the stone wall.

The sound of irregular impact is accompanied by a shaking up and down from time to time.

It is the voice that brings them hope, and it is also the shaking that brings hope.

Qian Tong, Yan Jinbai, and Gu Yuxi were awake one after another.

A trail of seawater slowly flows in from the esophagus.

The Hydra's teeth and other parts have begun to loosen.

The body that seals the blockage is no longer flawless.

Xu Zhi stretched out his slightly pale hands and touched the seawater mixed with the acid in the mouth of the hydra, and a little joy finally appeared on his expressionless face.

"We're going to be able to get out of this shell."
