Whoa, whoa, whoa!

In the dark depths of the sea, you can't see your fingers, only a slight sound can be heard, caused by a behemoth lifting the sea as it moves rapidly.

"This monster is simply a deep-sea submarine, no, it is moving faster than a deep-sea submarine!"

In the monster's mouth, Professor Yi Yu looked at the decreasing water pressure index, and was amazed in his heart, fast, it was too fast, the sea monster's forward speed was much faster than the two of them swimming, it could be described as galloping!

And in the big mouth of the sea monster, the metallurgical spacesuit does not need to resist strong water pressure, and the speed of energy consumption is greatly reduced, and on the basis of 24 hours, the time is extended!

In this kind of crisis, time is life!

"Haha, the water pressure is getting less and less!"

"It's coming! We're about to reach the surface! ”

After almost 2 hours of rapid progress, finally, the water pressure is getting smaller and smaller!

"Stop—"

Forward, forward, suddenly, Xue Yu "saw" a light appeared above his head, and hurriedly shouted to stop.

"What's wrong?" Professor Yi Yu asked repeatedly.

"There's a discovery!" Xue Yu said: "The visibility above has greatly increased, and there seems to be light!" ”

"It looks like we've reached the surface of the sea, and the water pressure has dropped to its lowest!" Professor Yi Yu also said, and as he spoke, he saw a long rope of water slowly retract, and finally retracted back on him.

This water flow rope is part of the metallurgical spacesuit, which just extended beyond the monster's mouth to detect the external water pressure, which is also an advantage of the metallurgical spacesuit, any part of it, can be used as a detector!

"Now...... Get out? Xue Jun asked a little excitedly, finally arrived at the sea, it's not easy, the monsters have been running for two hours, if you swim by yourself, you won't be tired to death.

"Get out!"

"Good!" Xue Jun nodded and said to Xiao Jin: "Xiao Jin, let this monster open its mouth!" ”

“……”

Xiao Jin didn't say anything, and after a while, the monster's mouth slowly opened, and suddenly, a huge stream of sea water poured in, and Xue Yu and Professor Yi Yu firmly grasped the monster's flesh and blood, so they barely were washed away.

Eventually, the monster's mouth was filled with seawater, and the sea gradually calmed down because the monster didn't swallow it.

"Let's go!"

The two of them jumped, using their hands and feet together, quickly stirring the sea water, and swimming out of the monster's mouth.

"Xiaojin, can you let it stay here all the time, maybe you need it?" Xue Yu said to Xiao Jin, this is also just in case.

"Goo!" The golden light flashed in Xiao Jin's eyes, and it sank into the monster's brain, and the monster began to wander around, but it did not leave.

"Tut-tut, it's really much brighter here than the deep sea, at least you can see the light!"

Professor Yi Yu looked at the light above his head, and said a sigh, and then he went upstream, "This is ...... Ice? ”

A moment later, his hand touched the glowing object, and it turned out to be ice, hard ice!

"Ice indeed!" Xue Yu also said.

"It seems that this planet is very cold, or rather, this should be the poles of the planet, and the sea we are in has frozen and covered with a thick layer of ice!" Professor Yi Yu frowned slightly, and said helplessly.

"So how are we going to get out and break through this ice?"

Xue Yan thought for a while and said, his right hand instantly popped out a spike, piercing the liquid gold spacesuit covering his right hand, and then with a force, "Click-" The spike sank into the ice, stirred hard, drew a circle, and a large piece of cylindrical ice was cut.

Yi Yu looked at this scene and didn't stop it, but the corners of his eyebrows kept wrinkling: "Xue Jun boy, do you know how thick this layer of ice is?" ”

"I don't know, it shouldn't be too thick!" Xue Jun shook his head!

"Try it first, but I always think this ice is unusual!"

Professor Yi Yu said in a deep voice: "On a gentle planet like the earth, the average thickness of the Antarctic ice is 1,700 meters, and the thickest part is as high as 4,000 meters. ”

Xue Yu stiffened, and also realized the seriousness of the problem, the liquid gold spacesuit could not last for 24 hours, and there was not much time left for the two of them, how could there be time to slowly chisel the ice?

"What then?" Xue Jun smiled bitterly in his heart, he went out of the deep sea, thinking that he could reach the land smoothly, but who would have thought that he would be blocked by the ice again!

"Pray! One can only pray that the ice is not thick! Let's dig for half an hour, if we can't dig up, we'll have to find another way! Professor Yi Yu was also helpless: "It's a pity that there is no sonar, otherwise the thickness of the ice can be detected!" ”

Xue Yu didn't speak, and continued to cut the ice, and as time passed, pieces of ice were cut off and fell into the seawater, and the ice cave that was chiseled became deeper and deeper......

Half an hour passed, Xue Yu chiseled an ice cave sixty or seventy meters long, the speed is not fast, however, the distance to completely chisel through the ice is still far away!

Or rather, he didn't know when he would be able to chisel through the ice, maybe only two or three meters left, maybe ......

Xue Yu's heart gradually sank, and his patience gradually wore out!

"Half an hour has arrived, boy Xue Shu, come down, we can't waste time on this!"

In the past half an hour, Xue Yu was chiseling ice, and Professor Yi Yu was not idle, he had been wandering around, hoping to find a way out, but in addition to the thick ice, it was thick ice, not to mention the passage, not even a slight crack!

He could only return disappointed!

"Poof—"

Xue Yu slid down from the hole and fell into the icy water, with a disappointed face: "I'm really unwilling!" ”

"There's no way around it, you're digging ice now, it's tantamount to a blind man touching an elephant, it's not much use!" Professor Yi Yu shook his head and said, "Let's go, go farther away and look for it, maybe you can find the blowhole!" ”

"From the dissolved oxygen in the ocean, it can be seen that there must be a place leading to the outside world, and this planet contains oxygen!"

The two of them are in a desperate situation, and Professor Yi Yu's rich knowledge and experience are fully reflected: "As long as we move along the place where the oxygen concentration is getting higher and higher, we will definitely be able to find the connection between this place and the outside world!" ”

Seeing Xue Jun's face full of disappointment, Professor Yi Yu couldn't help but comfort: "Hehe, don't give up hope!" ”

"Got it!" Xue Yu barely cheered up, glanced at the ice cave that had been chiseled, shook his head helplessly, and sat on the monster's back with Professor Yiyu, and then ordered the monster to swim forward.

At first, the oxygen concentration in the seawater was almost the same, and the monster moved aimlessly, but after more than an hour of walking, the oxygen concentration became higher and higher.

"Haha, that's the right direction, keep swimming, accelerate forward!" Professor Yi Yu continuously measured the oxygen concentration in the seawater through the metallurgical spacesuit, and finally found that the oxygen concentration in this sea area increased significantly, and there was a direction, the oxygen content was higher.

Under his guidance, the monster swam in that direction.

Finally, after nearly two hours of advancement, a huge light was projected in front of him, this light was not very bright, but in this dim sea water, it looked extremely conspicuous!

"Look! There it is! ”

Professor Yi Yu kept urging, Xue Jun was also excited, and the light in front of him was like a bright Milky Way in the dark starry sky, quietly lying in front of him, guiding the way.

After twenty minutes, the monster finally reached the bottom of the light.

"Haha! Fissure! It's a huge crack! ”

The light was transmitted from a super-large crack that was a kilometer or two wide and an unknown number of kilometers long, twisting and twisting and stretching to infinity!

And through the huge crack, you can only see the crystal solid ice, flashing with light, but you can't see the end of the crack!

Have no bottom!

It's a super big, super deep crack!

"This huge crack is where the sea and the land exchange gas!" Professor Yi Yu roared excitedly!

"Let's go up now?" Xue Yan couldn't hide the excitement in his heart, swallowed his saliva and said, he finally swam from the deep sea to the surface of the sea, and it took so long to appear here, the excitement in his heart can be imagined!

"Up! Why don't you get on! Professor Yi Yu waved his fist, and suddenly smiled: "But the task of climbing up is left to you, I can't do it!" ”

"Wrap it up on me!"

Xue Jun smiled and looked at Xiao Jin: "Xiao Jin, can you take us up?" ”

"Yes, yes, but I want to be full!" Xiao Jin was a little reluctant, but agreed anyway.

"It's okay! You just let go of your stomach and eat! ”

"Boom-" Xue Ji didn't hesitate, countless spikes appeared on his hand, and handed them to Xiao Jin's eyes, "Quack Quack-" Xiao Jin didn't know how to be polite, and ate it with relish.

Professor Yi Yu just watched, full of hope!

This time, I ate more than before, and I ate more than 30 spikes, so I couldn't get enough of it and didn't eat anymore!

"Kim, please!" Xue Yu and Professor Yi Yu looked at Xiao Jin in unison.

"Goo~~~" Xiao Jin shouted twice, his scaly wings opened suddenly, jumped out of the sea like a bolt of lightning, circled in the crack for a moment, and then swooped down, his sharp claws instantly grabbed Xue Yu's shoulders and rose to the sky.

"Whoa—"

Xue Yu and Professor Yi Yu are connected by metallurgical spacesuits, and the combined weight of the two is 300 pounds, but Xiao Jin seems to be as light as nothing, and the speed of flight is incredibly fast, and the ice on both sides flashes in front of him like a phantom, and in a moment, it disappears into the crack!

It's so fast!

"Boom—"

However, as soon as they left, there was a sudden thunderous sound from the depths of the seabed, like summer thunder, and like a volcanic eruption, rolling endlessly, one after another, and then the surrounding sea water rolled violently, as if boiling magma was surging, but it was suppressing.

"Boom—"

Finally, with an earth-shattering roar of thunder, a terrifying force erupted from the depths of the seabed, as if an atomic bomb had exploded, and the impact of the explosion was incredibly powerful, forming a huge shock wave.

Instantaneous—

The surrounding sea water is oppressed and gushing out in all directions, but it is covered with a thick layer of ice on all sides, where does the pressure pour?

This huge crack!

Suddenly, an endless stream of sea water poured into the crack, and then erupted upwards, erupted, erupted!

"What's going on?"

Professor Yi Yu at the bottom noticed that something was wrong, looked down, and suddenly his eyes widened.

Xue ...... Xue Shu, hurry, let it speed up! ”
