Beneath Deep Space

The world record for holding one's breath underwater can reach more than 20 minutes. However, holding one's breath while exercising will greatly consume the body's oxygen. It can only last for two or three minutes at most. Coupled with the small amount of air in the helmet, Yu Yifeng It only lasts for five minutes at most.

The five-minute countdown rang in my heart... We must do it as soon as possible!

Passing through this gate is simply the hardest hit area of ​​nanobots. In just a short time, various green marks were spread on the ground like soybeans, like a seaweed carpet, and this carpet was expanding.

It may be that the metal elements here provide them with abundant materials, which is why they expand so fast.

Yu Yifeng's scalp was numb when he saw it. If "Ling" hadn't labeled these robots, he would have had no choice but to give up this operation.

Maybe...you'll be disassembled as soon as you walk in!

Now he just needs to take some risks. He can only unconditionally trust "Ling" and has marked everything.

With no time to hesitate, Yu Yifeng's heart trembled and he swam sideways slowly. After taking off the power armor, of course there are benefits. You can sense the water flow, and your whole body is much more flexible.

However, such strenuous exercise causes the air in the helmet to leak out, and the air in the helmet is consumed, and most of it is quickly used up.

After carefully avoiding the algae marks at the door, Yu Yifeng stepped on a metal floor and quickly pressed his electromagnetic rifle against a machine and pulled the trigger. "Bang!" The ground suddenly smashed a nearby instrument to pieces.

Destruction is always easier than creation, and it is impossible for these high-precision equipment to completely defend against human high-speed bullets.

The huge recoil of the gun caused his whole body to tilt suddenly, and he almost came into contact with a green algae mass.

In an instant, a cold sweat broke out behind him again, and he quickly stabilized his figure. You know...it's nanorobots wrapped inside!

His racing heart was increasing oxygen consumption, and he was actually sweating even if he was immersed in sea water. However, he had no way to control this physiological reaction and could only speed up his hands.

"Fucking dangerous!"

Things like nanorobots are completely unreasonable.

As soon as it comes into contact with human cells, it will forcibly extract certain metal elements inside as nutrients for self-replication. Don’t think that human cells do not have metal elements. Calcium, sodium, potassium, magnesium, and iron are basically found in every cell. Without any one of them, human cells will die.

If infinitely replicating nanorobots are used to destroy the world, it will definitely be simpler and more effective than nuclear bombs, and there will be no life left behind.

Be anything!

This kind of disaster is called "grey tide" in some science fiction novels. He didn't expect that he could witness it with his own eyes... and he didn't know whether these things could be copied infinitely.

Yu Yifeng couldn't help but cursed again and again in his heart, and took the last breath of air from the helmet.

"The last three minutes..."

He broke the instruments one by one and used the laser cutting tool he carried to randomly cut out some small chip-like things. He didn't care to distinguish what they were and threw them directly into the helmet.

Shine a flashlight around and immediately see an elevator facility. It seems that this laboratory should have underground space!

But apart from the elevator, no other entrance or exit was found... The elevator seemed to be out of power.

There is no defense mechanism in the laboratory, and maybe some circuits were destroyed by nanorobots...

When I turned around again, I saw that these green masses were spreading rapidly at a speed visible to the naked eye! In just a short time, most of the laboratory was occupied, and there were clumps everywhere.

Yu Yifeng gritted his teeth again and spit out a lot of turbid bubbles. This silence was like a big shadow hand slowly strangling his throat.

This is underwater, and it is very inconvenient to move around. The space is dark and small, and the only light comes from the helmet and the submarine outside...

Claustrophobia, hypoxia, and the fear of death are affecting his deep inner emotions. He feels a little dizzy and instinctively wants to breathe. This is a sign of great psychological pressure.

"As soon as possible, within two minutes..."

At this time, he heard a soft "bang" sound outside. It should be that the oxygen bottle of the power armor exploded. He screamed in his heart that something was wrong again. This explosion would definitely spread the nanobots everywhere.

At this moment, he couldn't think of so much. He calmed down again, turned around and swam toward something that looked like a radar.

This thing is about one meter tall, and it feels like it is something very important.

Yu Yifeng fired several shots at the bottom of the radar, then cut it off with a cutting tool. He lifted it hard and was shocked.

"Good weight!"

"One more minute!"

If you bring this thing with you, you will definitely not be able to swim up! what to do?

He was anxious, but at this moment, he suddenly heard the exclamations of Zhao Yao and others. Something seemed to be happening outside.

"Quick, Captain, come out quickly!"

"Green...green!"

"Come out! The speed... is about to be surrounded!"

These sounds are transmitted through the power armor's broadcast in the water, and they sound like a strange "buzzing" feeling.

But Yu Yifeng still didn't understand what was happening. The group of nano-robots at the entrance of the passage was almost closing the exit!

At this moment, he dared not hesitate and lifted up the radar with a sudden force. Good guy, including the buoyancy of the water, it weighs one or two hundred kilograms!

"...I can't swim!" This strenuous exercise increased the consumption of oxygen, and he felt that large areas of darkness had dimmed before his eyes, which was a precursor to severe hypoxia.

If you take it with you, you will never be able to escape!

"Quick, Captain, quick!"

"...Hurry!"

In this extremely dangerous situation, Yu Yifeng's body was filled with adrenaline. He forced himself to calm down and faced a huge choice...

First, throw away the radar and swim out alone. After all, there is something harvested in the helmet!

Second, search for the entrance to the space below, and then find a way out. This may be an opportunity... It's hard to say what the isolation layer below is, and there may even be air!

The veins on Yu Yifeng's forehead were pulsing, and his face was livid. He didn't know whether it was because of holding back or some other reason. The elevator is not powered on and must be out of service. Where is the entrance? Has it been blocked by nanobots?

The vast area in front of him became dark, and he bit the tip of his tongue suddenly, and a spicy taste suddenly poured into his throat.

You can't get dizzy now, you will definitely die if you faint!

Just when he was about to give up the radar with regret, he suddenly felt his whole body suddenly lighten up, as if being held by a big hand, and rushed out towards the exit.

Yu Yifeng was in a state of extreme concentration at this time, relying solely on one breath to hold on. I was suddenly yanked without any preparation, and I felt nervous. I drank a few mouthfuls of seawater, and then choked my bronchus. The entire lungs reacted strongly, and a large number of air bubbles were spit out.

"There are enemies!" He subconsciously wanted to shoot behind him. A person's ability in the seabed was too limited. .

But in his confusion, he quickly thought that it was "Ling" who suddenly had an enlightenment and was helping him...

"Hurry! Hurry!"

"...It's closed!"

"Fuck... don't stop me!"

The algae at the exit has overflowed. In fact, these are signs of "Ling", and they are about to block the entire exit.

Suddenly, a huge wave of water forced them away. Then, these marked seaweeds also came into contact with the nanorobots and were quickly swallowed.

But taking advantage of this moment, Yu Yifeng had passed through the exit like a fish and shot out like a cannonball.

The next moment, several arms had firmly grasped him.

"It's the captain!"

Zhao Yao was overjoyed. When he saw the power armor on Yu Yifeng disappear, he suddenly thought of something. He wanted to unplug the oxygen tube on his powered armor, but then he thought that Yu Yifeng's lungs were full of water and he could no longer breathe oxygen.

He could only shout: "Quick! Retreat, retreat!"

"Prepare high-yield nuclear bombs! And pulse bombs..."

At this last moment, Yu Yifeng was exhausted. There was a large area of ​​darkness in front of him, but there was no oxygen supplement. He only saw his teammates and... a green ball... This thought gradually dissipated. Finally passed out.

But the thing he was holding in his hand... still didn't let go!
