At this moment, Chen Ling is not as relaxed as it seems on the surface, his legs are like being filled with lead, they are too heavy, and it takes a lot of strength to lift it every time, if he doesn't hold his breath, I'm afraid he won't be able to hold on.

It is important to know that during muscle exercise, muscle glycogen in muscles will produce lactic acid, as a strong organic acid, lactic acid dissociates to produce H ions, causing a decrease in PH value in muscles, and the accumulation of H ions will interfere with the combination of calcium ions and troponin, thereby interfering with the muscle contraction process and leading to fatigue.

When the intensity of exercise is relatively low and the duration of exercise is relatively long, muscle glycogen will be broken down to provide energy for exercise, however, muscle glycogen stores are limited (the average person's muscle storage is 300-400g), if muscle glycogen is broken down and consumed in large quantities, muscle fatigue will occur.

Chen Ling maintained high-intensity exercise for more than an hour, and his muscles produced a large amount of lactic acid, and a large amount of muscle glycogen was decomposed and consumed, even if his physical fitness was 3 times that of ordinary people, he could not bear it.

Sweat had already penetrated the military uniform on his back, as if it had been fished out of the water.

Whew.....

Chen Ling's breathing became heavier and heavier, and he became more and more rapid, and the long and fast running consumed his great physical strength.

"How far is it?"

"About five kilometers. ”

Chen Ling let out a breath and said, "Then let's finish." ”

"Ahh

Chen Yongjiang thought that Chen Ling would stop, get in the car, and take a rest, but as a result, he still had to run!

"Chief, come up and rest, if you run badly, I can't explain to the regiment commander. ”

The so-called straw crushes a camel, Chen Ling ran to this extent, it should be almost to the limit, although the back is only 5 kilometers, but it is precisely these 5 kilometers that are the most difficult to hold.

If you run out of three long and two short, wouldn't you be guilty of too much?

"It's okay, go on, my own body, I know!" Chen Ling said.

Chen Yongchang let out a long breath and could only continue to drive forward.

He was really worried that Chen Ling would run so wildly, would he run away from his body?

There has never been such a bull in the 128th regiment, don't make an accident.

Chen Yong saw that Chen Ling's running speed slowed down a bit, and hurriedly slowed down the speed of the car and controlled it at about 20.

This reassured him a lot.

That's the normal pace of running.

However, Chen Yong thought that Chen Ling had insisted on holding out at a speed of 40 km/h for an hour before, and this kind of stamina, physical strength, and speed were much better than the special forces he knew!

"At this time, if he can still run 5 kilometers, he will definitely be an iron man!"

In addition, Chen Yong also noticed the crowd behind him who drove and followed the shooting, no need to guess to know that Chen Ling was running so wildly, filming it, putting it on the online platform, eating melons and crowds, it must be fried!

Not to mention those people who eat melons, even if it is themselves, they all feel crazy.

Chen Yong thought for a while, it was still necessary to report the situation to the head of the regiment, so he took out his mobile phone and dialed Zhang Tuan's number.

"Leader, it's me, Xiao Chen, the situation is like this......"

Chen Yong briefly reported the situation, and finally said: "How to deal with the tail in the back of the car?"

In the 128th regiment, in the office of regiment commander Zhang Ting, he discussed the next training arrangements in the regiment with several cadres in the regiment.

Suddenly, Zhang Tuan stood up abruptly and said loudly, "What did you say, that kid ran over?"

Chen Yongdao: "Yes, all the way from the station, ran to the 128 regiment, only 5 kilometers away, behind the car, followed by a bunch of curious people, I suspect that soon Douyin, Kuaishou or something, immediately exploded." ”

Zhang Tuan was stunned for a moment, and muttered to himself a little distractedly, and said: "It's a little interesting, it's the first time I've heard of such a newcomer, no wonder as a recruit, one person can kill a group of drug dealers with a knife, it seems that this is reasonable, this kid is a ruthless person!"

"What?" Chen Yong said in surprise, "He killed a group of drug dealers by himself, with a knife, and the head of the group, you didn't lie to me, did you?"

Chen Yong is a veteran, and it is the first time he has heard such a fierce thing.

As the ace combat regiment of the military region, in addition to regular training, they often go to the border to carry out patrol missions and have also dealt with armed drug traffickers on the border.

Those are a group of outlaws, and their combat effectiveness is not inferior to them in any way, and some are even comparable to the special forces.

One man, one knife, a bunch of people? How does it sound like a joke.

Zhang Tuan came back to his senses and said loudly: "You don't care about this, anyway, just bring him over, as for the tail, broadcast a warning, this is a forbidden place in the military region, they will not approach, be careful not to scare the people, just warn, in order to show respect, I took all the cadres in the regiment to pick him up." ”

Chen Yong was stunned.

"Zhang Tuan brought the whole group of cadres out to greet him, this scene is a bit big!"

Chen Ling didn't know that he had already alarmed Zhang Tuan all the way back, and he still ran forward step by step.

"One step, two steps......

During the run, Chen Ling's sweat kept falling, and dazzling marks were formed on the ground.

With such an intensity of extreme off-roading, it was almost to his limit, and his whole body felt like it was about to fall apart.

Because of the heavy breathing, the lungs were about to vomit.

During the exercise, the body consumed a lot of water, and Chen Ling's throat was dry, as if it was about to crack.

"Extreme off-road is really not a sport that ordinary people can bear. ”

If it weren't for Chen Ling signing in to obtain extreme off-road skills and further strengthen his body, he would have been unable to hold on.

Suddenly, a crisp prompt sound sounded in Chen Ling's mind.

"Ding! The host meets the conditions for repeated check-in, does it sign in?"

Chen Ling was stunned for a moment, and his heart was overjoyed.

"There's still one, sign in!"

"Ding! The host enters the crazy extreme off-road state, and obtains a future genetic physique enhancement, strengthening requirements: break the physical limit off-road again. ”

"I'll rub!"

Chen Ling, who was very excited, almost fainted.

He is already at the limit, and he has broken the physical limit again?

Also, what is the future genetic constitution?

Is it possible to change the human body's genes and make the body look like it has superpowers?

Chen Ling's first thought was the various genetic research and modification in science fiction films.

That's what comes to mind, though.

Chen Ling couldn't help but complain in his stomach: "System, are you playing with me? Don't you see that I'm almost tired like a dog now? And let me break the limit again, you really think I am made of iron?"

The system quickly appeared with a prompt: "This is the physical potential of the future soldier king, which can be equivalent to 4 times the physical fitness of ordinary people, and the host can choose to do it now or choose to delay." ”

"This can be ...... But as for breaking the limit again, it can only be said about the 128th regiment. ”

Chen Ling's eyes lit up!
