Special Forces: At the beginning, Long Xiaoyun took him to get the certificate

The water was blown away, and the water was turned off.

"Select activation function 1!"

Chen He's mind moved.

The next moment, a stream of subtle electric current appeared in Chen He's body, as if flowing through his whole body, covering his entire body, and constantly stimulating every nerve in his body.

Along with the stimulation of this electric current, the surface of his skin began to change slightly, as if it was gradually undergoing a transformation.

This feeling is indescribably refreshing.

Not only that, Chen He can feel that he has begun to control his body functions, such as heartbeat, breathing, muscle peristalsis, and even a feeling that he is like a fish in water and will not suffocate.

"Isn't this too magical?"

As the subtle oxygen in the water penetrates through the skin, Chen He feels like breathing.

People breathe through their lungs, absorb oxygen, and support the body's circulation.

Energy-saving mode means that oxygen can be absorbed through the skin and transferred to the body to replace the function of the lungs.

The simplest way to put it is that he doesn't even need lungs to breathe!

"This function is awesome. It's more than just energy saving. It's a completely ancestral ability."

Chen He couldn't help but exclaim.

Those who have learned about the history of human evolution know that humans first evolved from water.

When the fusion was complete, Chen He felt that he could breathe underwater.

"No wonder it's called a must-have for PUBG."

Chen He's confidence increased greatly.

"I just don't know how long this ability can last? Can it last for a long time? It's like a life instinct."

If this powerful function can be possessed for a long time, Chen He will not need an oxygen tank when he encounters underwater training or underwater combat. He will be like a fish swimming in the water.

How convenient will this be? It's like cheating underwater.

As a soldier, underwater kung fu is the most basic subject. Chen He is already invincible with this ability.

The system explained: "The host's physical attribute is 2, and the energy-saving mode can allow the body to last for 2 hours."

Chen He was surprised and said: "Two hours? Not long?"

The system said: "It can only be adjusted, not really change the body, but it can extend the survival time according to the changes in the host's physical attributes. At present, 2 hours is already the limit."

Chen He was a little confused!

If it were normal, if he could dive for two hours, it would definitely be a world record, and no one would be able to break it in the next 100 years.

But now it is a desperate situation!

Two hours is not enough.

The reservoir collapsed underground, and the tunnel was flooded. I don't know how much water poured in, and there are collapsed soil and rocks. People outside want to dig in, let alone two hours, even 20 hours may not be able to open it.

Two hours is a drop in the bucket.

Chen He frowned, and the surging water had risen to his chin.

And there was still water seeping in from the surroundings. It was a matter of time before the entire space was flooded.

"It's still a desperate situation. It's impossible to rely on people outside to get through and save me. Now I can only rely on myself."

Chen He was unwilling to die like this.

He had hundreds of billions of assets waiting for him to inherit. He was still so young and handsome, a rich and handsome man, and he also got a great computer system. His life was just about to start cheating. You let me die now?

No one would be willing to accept this!

"By the way, there is still a chance to strengthen!"

Chen He immediately used the opportunity to strengthen.

Suddenly, a strong current surged through his body again, and his body seemed to have changed from the inside out.

The surface of the skin, muscles, tendons, bones, internal organs, etc. were all strengthened...

Just a few seconds later, Chen He's body was strengthened, and then it seemed that a powerful force was integrated into his body.

When he clenched his fist, a more powerful force surged up.

This force was much greater than the force Chen He had used before.

"Enhancement completed, all attributes +0.5!"

Personal attribute list updated.

Host: Chen He

Level: Level 3

Data flow attribute.

Motherboard performance: 2.5 (ordinary person: 1)

Memory size: 2.5 (ordinary person: 1)

CPU speed: 2.5 (ordinary person: 1)

Activation function: comprehensive physical examination, enlarge and bold, recycling bin (2M), energy saving mode

Comprehensive strength evaluation: 4

Upgrade experience value: 0/400

Chen He glanced at the attribute list. The physical attribute reached 2.5 and the comprehensive strength evaluation reached 4. From this value alone, it is better than ordinary

He is much stronger.

The 2.5 attribute has exceeded the physical fitness of ordinary special forces soldiers. In other words, if Chen He participates in the special forces selection now, he can already far exceed the physical fitness level alone.

Such physical fitness improvement is faster than the speed of riding a rocket.

Professional athletes may not be able to achieve the physical fitness after years of hard training, but Chen He only took less than half a day.

If Chen He is given more time to grow, I don’t know how strong he will be.

After strengthening, Chen He felt that his injuries had recovered a lot. The arm that used to hurt was almost imperceptible now.

It must be said that this strengthening effect is better than any panacea.

"The physical attribute has reached 2.5, and the survivability in energy-saving mode can reach 2.5 hours. This is my only chance to survive."

"Full scan!"

The tunnel just collapsed again, and a large amount of water poured in. If there is water pouring in from the crack, when the water is full, can't I swim out through the crack?

Of course, as long as the crack is big enough, I have a chance!

Swish!

Under the computer's comprehensive scan, everything around him seemed to be imprinted in Chen He's mind, and presented one by one.

What Chen He is looking for now is the best escape route.

If it were someone else, in this situation, it would definitely rely on luck. Chen He relies on technology, and in terms of probability, it is much more likely than others.

"Found it!"

In just a few breaths, the computer system scanned out the best moving route.

Chen He did not stop, and immediately grabbed the steel bar and swam over.

Plop, plop...

From time to time, rocks fell on Chen He's head, hitting the water surface and splashing water.

Under the water, there are all kinds of upright steel bars and some concrete pillars... Dangers are everywhere!

If there is no scanning function to find the most optimized route, Chen He will need a lot of experience just to avoid them.

After a while, Chen He swam to a passage.

This is a passage that was cracked by the impact of water pressure.

The entrance of the passage is less than 50 centimeters wide and very irregular. The further you go in, the narrower it gets.

It is also the only place here that is not flooded.

Chen He's only option is to dig out from here.

"With 2.5 physical fitness and the violence of [Enlarged and Bold], it is not impossible to dig out a passage."

"Go!"

Chen He has no way out and can only rush forward.
