Fast.

Extremely fast!

The suction power below is like a black hole! Jiang Xian's eyes instantly fell into darkness, and no one dared to turn on the lights - if he really entered Yun Mengze, Yun Mengze was really as they speculated, an infernal hell where the weak and the strong eat, and these lights were the guide to death.

What a strong suction...... Jiang Xian gritted his teeth and felt the water flow by his side. He estimated that the current speed was close to that of the car, and the water friction on his body was as if it were substance.

No one dared to raise their heads, and their whole body was clinging to the back shell of the giant turtle. Fly through a pure, lightless world. He didn't look at others, but he knew that everyone was beating like a drum at the moment.

After all, he is the same.

No one knew where the waterway led, no one knew if Jiang Xian's guess was correct, and no one knew if they could still see the sun. Time is like a sickle of torture in pure darkness, slowly cutting everyone's nerves, and the dull feeling turns into anxiety and apprehension, which becomes more and more painful as time passes, and frantically gnaws at everyone's reason.

Under the deep lake, life is like a year.

The feeling of depression, sleepiness, and suffocation is like a twisted hand that grabs all the nerves of a person. The five senses and the mind are multiplied in pure darkness. Jiang Xian didn't close his eyes, but gritted his teeth and stared ahead. Time seemed to have lost its meaning, and as the dive time became longer and longer, countless distracting thoughts unconsciously arose.

Will it die?

Will you be trapped in this waterway that doesn't see the light of day?

Even after so much exploration, he couldn't help but ask himself at this moment.

Their compressed air bottles are already custom-made in the most dive-friendly size – the larger the bottle, the more oxygen is stored. No matter how big their compressed air cylinders are, they can affect their movements. Even then, it was only enough for forty minutes. Each of them carried four bottles of compressed air, that is, if they could not see the exit for two hours and forty minutes, they would definitely die!

And now, at least an hour has passed.

One hour and ten minutes...... Twenty minutes...... Forty minutes...... Two hours!

Jiang Xian knew that I was afraid that the spiritual support of the three professors had reached the limit, and this kind of lightless claustrophobia was too challenging for people's mentality. However, even if the other party is by his side, he can't help it.

Hurry up...... Faster!

He prayed desperately in his heart, as if he heard his prayer. Just two hours and ten minutes later, he suddenly saw ...... There's a little light ahead!

The faint light is like a torch that breaks through the darkness. At the same time as the bright light appeared, he clearly felt that the bodies of the three professors moved.

Where there is light, it represents the exit of another world! At the very least, it means that they probably won't be trapped in the waterway!

The further you go, the clearer the light becomes, and the water begins to turn blue, but not clear. After another ten minutes, they finally saw that the procession was marching through a passage at the bottom of the lake.

Ahead is the exit...... According to the refraction of light, it will not be more than fifty meters above the water! The hanging heart fell back into his chest, Jiang Xian breathed a sigh of relief silently, and quickly swept over all the giant turtles, only then did he close his eyes as if relieved.

The giant turtles were all around, and none of them left. And the people on the giant turtle slowly twisted their heads and looked at everything around them. This proves that no one has lost consciousness in the mental oppression just now.

This is undoubtedly the best news.

Now is not the time to relax...... Jiang Xian immediately opened his eyes and looked around solemnly—they might have entered Yun Mengze's range, if Yun Mengze was really as they speculated, they were already hovering on the edge of hell.

Go inside, and it's the world of demons.

Enough to prove this, that is...... The speed of the giant turtle did not slow down in the slightest, but it involuntarily leaned to the sides or to the bottom of the lake.

They are scattered...... This is obviously a world familiar to giant turtles, and according to their habits, most creatures will let their guard down when they return to their territory. But the giant turtle didn't, no...... Instead of relaxing, they move towards more secluded places. Whether on the sides or below the passage, try to minimize the amount of time you spend unsheltered – an instinctive reaction that creatures have formed in a hostile environment.

Other words...... Is there something in this body of water that makes it fearful and irresistible...... Jiang Xian's muscles tensed all over his body, staring at the front.

They were only about twenty meters away from the entrance of the cave.

Time seemed to be silent, the speed of the giant turtle slowed down, and finally something else appeared in front of it, unexpectedly...... It's the roots of a tree!

I don't know what kind of species, the volume is very large, like a python, tangled at the bottom of the water, through the turbid lake, you can vaguely see a huge tree trunk, covered with shellfish, aquatic weeds, algae, forming a layer of cyan armor, but straight out of the water. A sense of savage mystery strikes everyone's heart like a sharp arrow.

Underwater forest!

When they saw this underwater forest, the eyes of the three professors lit up. It can grow into an underwater forest, which means that the water quality has not changed much, at least for more than a thousand years, and ...... There is a need for light, a complete food chain, which means they really might have found a paradise!

Twenty meters to go, you can see its true face, and the compressed air bottle has only the last twenty minutes left...... Blazing eyes all looked at the entrance of the cave. At this moment, however, all the turtles stopped swimming at the same time.

The incomparably quiet underwater suddenly shrouded in an ominous atmosphere. Just ahead, the fish that had been foraging for food seemed to be frightened by something and fled in all directions. The giant turtles quietly lay down more than ten meters away from the entrance of the cave, their heads and claws all retracted into their back shells, like a stone at the bottom of the lake.

The waves swayed, and the algae, the aquatic weeds, began to deflect in one direction - it was a sign of a sudden change in the current, and everyone instinctively held their breath. In the next second, a huge figure suddenly slashed through the hole, obscuring all the light, and in the alternation of light and dark, the bloated head, full of sharp teeth, lizard-like body, and typical eight fins flashed in front of everyone's eyes.

Jiang Xian's eyes were fixed on the three professors, and he could clearly see that their mouths were open at the same time, their eyes were as wide as copper bells, and after their lips trembled a few times, they muttered five words.

There was no sound in the water, but Jiang Xian knew that what they were talking about ...... Yes: Hissa root toothfish!

A living Hissa root toothfish, the overlord of the water of the Carboniferous period! Apex Predator! The body is at least eight meters long and can weigh up to 4 tons. The skull is huge and terrifying, and it is the largest freshwater carnivorous fish from the Proterozoic to modern times!

He finally understood why these turtles had evolved the ability to turn blood into ink...... In the face of the terrifying bite force of the Hiss's root toothfish, not to mention the turtle, even the ore will be bitten to pieces, and the current shark is nothing compared to it.

The huge body of the fish flew through the cave, and the cave and the entrance were mostly covered by several fallen trees, and its huge body could not enter. However, just as its tail slashed through the cave, an even larger head slammed into it!

In the cave, everyone opened their mouths wide, and this movie-like scene happened in front of them, and the shock that hit the heart could not be expressed in words. They could see clearly that it was a huge crocodile head, three meters in size!

Unlike modern crocodiles, it has sharp teeth in its mouth, but it has a huge pouch in its jaw. Two monsters chased after me, churning the waters into a dusk in a matter of seconds, and the battlefield was not far from the cave.

Jiang Xian didn't know what kind of monster this crocodile was, but it was not good at daring to chase the overlord of the Carboniferous water. Importantly...... They only have fifteen minutes left in their oxygen stock!

Not far from sight, the battle in the water made the bottom of the lake muddy, and no one expected that they would encounter such a grand welcome ceremony just after entering the new world. It's not unexpected, but it's scary...... Because of this vicious fight, the giant turtles ...... Don't dare to move!

They lay quietly at the bottom of the lake, apparently trying to wait for the war to end. Time is like a blunt knife, a knife that cuts everyone's flesh. One minute...... Two minutes...... Three minutes later, Jiang Xian finally gritted his teeth and let go of the vacuum glove.

As a team leader, he has to make a choice, and it's his responsibility.

He gestured quickly – all in the months of training that everyone had mastered. He gestured quickly, even if the oxygen was only ten minutes left, and he didn't panic at all.

Only he knows how anxious his heart is, but this feeling must not be expressed, the Lord will be chaotic first, and the whole team will die at the gate of the new world at once!

After two minutes of expression, Jiang Xian immediately swam away from the giant turtle. Immediately after that, the warriors on the backs of the other giant turtles released their gloves, and finally the three professors let go. At the same time as he let go, he was grabbed by several warriors and leaned against the rock wall of the passage.

Then, Jiang Xian took out his gun.

Shoot shark guns.

He reached out and made a gesture, and then aimed his shark gun at a giant turtle. With his movements, the shark shooting guns of the dozen or so people around him all raised their guns, aiming at the same giant turtle.

Two.

Jiang Xian stretched out his second finger, and the water was so quiet that it seemed that they could hear the second hand clicking, and everyone couldn't help but swallow their saliva.

Three!

As the third finger was raised, Jiang Xian immediately pulled the shark shooting gun, and at the same time, more than a dozen spear tips shot out at the same time, instantly shooting a giant turtle into a thousand holes!

Black blood flowed out...... And more and more! Soon a black mist was formed and floated out of the cave, Jiang Xian did not hesitate, and immediately shot at the other giant turtles - the moment others could still see his movements, the next second, he was engulfed in the blood mist.

Four black mist rose at the same time, drifting towards the outside of the cave, engulfing the entrance of the cave in an instant, spreading more and more.

And inside the cave, everyone's eyes looked at Jiang Xian at the same time, and their hands had already been placed on the backpacks on both sides of the backpack - there were disposable jet devices that were enough to carry them out of the water.

It takes a perfect timing, though!
