Nostrils borrow.

It's a very novel experience in life.

The experience was not good, the hydra's nostrils were filled with extremely slimy liquid, and the light showed a yellow color of feces, and when it penetrated, Xu Zhi felt that something was surging in his throat.

This liquid even has a corrosive effect on internal gases.

But the ending was satisfying, Xu Zhi kicked a cartilage in the nostrils of the hydra, and they finally entered the mouth of the snake, making the space they were in bigger.

Compared to before, the hydra wanted to devour them to satisfy their hunger, and at this time it took the initiative to enter the mouth of the snake, which is somewhat peculiar.

But the Hydra, which had only a faint chance of life, no longer had the strength to use them as food.

The Hydra's tightly closed giant mouth forms the best isolation.

Hidden in the mouth of the hydra, the power from the water pressure suddenly decreased, and as the speed of the hydra fell, it was difficult for them to even feel the adsorption power of the sea eye at this time.

Qian Tong's internal aura was suddenly flourishing, and he forcibly stretched out a space in the mouth of the hydra, which was full of fleshy thorns.

It's like being in a submarine, which isn't perfect.

The other party's head became a temporary safe haven.

There was a trace of sea water everywhere, and the tongue of the hydra, which was at least half a ton, was squeezed from time to time, but compared to being in the eyes of the sea outside, it was undoubtedly much safer at this time.

"What should I do?"

Qian Tong took out the crystal bottle hidden in his chest, and put the pill into the mouths of the two people with blue faces.

Seeing that the faces of the two of them improved.

Yan Jinbai and Gu Yuxi's eyes also began to try to open, staring at this strange scene.

Qian Tong's lip-on-lips question made Xu Zhi a little confused.

In that situation, the choice he made was not much better than that of Qian Tong, he just wanted to live a little longer and live a little longer.

But the Hydra's skull is not a viable space, they have to breathe, they have to eat, drink, and endure constant squeezing.

Without vigorous movements, it was quite easy for a master cultivator to hold his breath for twenty or thirty minutes, while a grandmaster could easily extend it to one or two hours.

But they've been through a lot of struggles before.

From surviving for one or two minutes, to surviving for more than ten minutes to twenty minutes.

If you can't complete the deep sea escape, you will still inevitably die.

Where can the eyes of the sea lead in this short period of time?

The formation of sea eyes is mostly due to the formation of some kind of void in the seabed, and seawater gushes from the high sea level to the low sea level.

There is an entry into the water and an exit point.

Whether this passage can be passed through by the Hydra, Xu Zhi continued to run the Qigong with his chapters, and there were countless speculations in his mind.

None of them are reliable.

Everything is handed over to chance.

This is even more unreliable than escaping on a copper whale back then.

The copper whale is alive anyway, and has the instinct to escape, and the hydra can basically be regarded as dead, so it can only go with the flow.

Two or three minutes have passed since entering the Hydra's skull.

Even if he gets out at this point, it will be difficult for him to float back to the surface and will eventually be sucked deeper into the seabed.

It's not much different from hiding inside the head of a hydra, maybe he'll die a little earlier.

"The hydra doesn't have gills to filter oxygen, so downward, we go down the throat to see if we can find its alveoli, which may still have some oxygen stored in them, which can prolong our survival for some time."

Gu Yuxi's lips squirmed, and a trace of extremely low voice came into Xu Zhi's ears.

Seconds after waking up, they clearly figured out where they were.

Xu Zhi and Qian Tong looked at each other, and suddenly began to squeeze in.

It's not easy to get into the Hydra, and it's even harder to get out.

But compared to sitting in the mouth of the snake and waiting for death at this time, they have to do something, whether it is right or wrong, they always have to try.

The tongue of the hydra is covered with barbs, and the point leading to the throat is also full of crooked barbs.

If it weren't for the fact that it was no longer able to move, with a slight exertion, the barbs would straighten in an instant.

Any prey that enters the mouth is subjected to the pain of skinning and piercing.

With his left hand wielding the Great Compassion Sword that Yan Jinbai had newly acquired after he was promoted to master, and holding his Rescue Knife in his right hand, Xu Zhi unceremoniously waved his weapon against the barbs that stood in the way.

The body of the snake more than 30 meters long was straightened by the force absorbed by the eyes of the sea, which made the esophagus almost stretch into a straight line.

Passing through the barbed area of the snake's mouth, it enters the blood-colored esophagus.

The extremely compressed esophagus finally has a gap, which can barely pass through without releasing internal qi and supporting the space.

There was the sound of Yan Jinbai and Gu Yuxi's extremely heavy breathing behind them, even if the esophageal passage was densely covered with extremely turbid acidic rancid gas, they couldn't take care of it too much at this time.

The two Dragon Tiger Pills that should have been handed over to Li Duohuang were put into his mouth, and the damage caused by inhaling acidic gas could also be buffered back.

With air, this passage can also be used for short conversations.

"Later, I will pass on to you a technique of death for the people of Yingguo, "Hanzhang Closed Qigong", and I have also made some slight adjustments to make it more suitable for our Dongyue cultivators."

"The greater the pressure of this exercise, the faster you can cultivate, as long as you don't move, you can eventually make your skin absorb the residual oxygen in various environments, form a balance with your body, and live for a longer time after holding your breath."

Xu Zhi kept squeezing into the body of the hydra, and also introduced his life.

This exercise is suffocated, some people are suffocated to death, and some people have learned it.

It's risky, but it's fast.

If you can learn it, you can live for a few more hours even without air.

When Qian Tong took the route of Huang Putu, he practiced the step-by-step closed qigong, while Yan Jinbai and Gu Yuxi practiced too fast, the time was too short, and many abilities were not complete.

The two of them swallowed the Dragon Tiger Great Returning Pill, and it should be no problem to borrow this valuable medicine to get started with a breath-holding technique, and they will not die if they practice.

At this time, the test for them is more about the ability to understand the fusion exercises in an instant.

Can a practice be started with self-analysis after being prompted once or twice?

There won't be much time for them, and there won't be much opportunity.

Coming to this place, even they can't do anything about breathing.

If it is death, you can only watch the other party die in the process of lack of oxygen.

As Xu Zhi laboriously peeled open a closed wall of flesh, the space suddenly opened up, and they began to burrow into the body where the heads of the eight giant snakes converged nearly thirty meters down the esophagus.

This is a rather empty space, even if it is oppressed by the sea, it is the size of a quiet room at this time.

Eight esophagus converged, and they were also connected to the stomach that was still trembling slightly.

When you enter this place, the soles of your feet are sour water, and the rancid sour air is thick to yellow.

The air seemed a little slimy.

Facing Gu Yuxi, who only had some internal qi support, Xu Zhiyi pointed at the other party's Yin Tang, and began to recite the spiritual language he muttered.

After reciting it twice, he also pointed to Yan Jinbai's Yin Hall and taught this closed qigong practiced to death without dying.
