At this moment, Chen Ling was not as relaxed as it seemed. His legs seemed to be filled with lead, which was too heavy. It took a lot of effort to lift it up every time. If he hadn't held his breath, he would probably not be able to hold on.

It should be noted that during muscle exercise, muscle glycogen in the muscle will produce lactic acid. As a strong organic acid, lactic acid dissociates and produces H ions, causing the PH value in the muscle to decrease. The accumulation of H ions will interfere with the binding 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 decomposed into exercise to provide energy. However, the reserves of muscle glycogen are limited (the storage capacity in ordinary people is 300-400g). If muscle glycogen is decomposed 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 lot of lactic acid and decomposed and consumed a lot of muscle glycogen. Even if his physical fitness was three times that of ordinary people, he could not withstand it.

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

Huhu...

Chen Ling's breathing became heavier and faster, and it took him a lot of energy to run quickly for a long time.

“How far is it?”

“About five kilometers.”

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

"ah!"

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

"Chief, come up and rest. If you run away, I can't explain to the team leader."

The so-called straw crushes a camel. Chen Ling has run to this level, and it should be almost the limit. Although it is only 5 kilometers behind, it is the most difficult to persist in these 5 kilometers.

If I have a bad situation, wouldn’t I be too guilty?

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

Chen Yong let out a long breath and could only continue to move forward.

He was really worried that Chen Ling would have lost his body if he ran so crazy?

There has never been such a great man in the 128th Group, so don’t cause any accidents.

When Chen Yong saw Chen Ling's running slow down a little, he hurriedly lowered the car's speed and controlled it to around 20.

This made him feel much more relieved.

This is the normal speed of running.

However, Chen Yong thought that Chen Ling had lasted for an hour at a speed of 40 kilometers per hour, and his endurance, 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 people driving and taking pictures behind him. No need to guess that Chen Ling ran so crazy and took the photos and put them on the online platform. The people who were eating melons would definitely be in a mess!

Not to mention those people who are eating melons, even themselves feel like they are going crazy.

Chen Yong thought for a while and it was still necessary to report this situation to the group leader, so he took out his cell phone and dialed Zhang Tuan's number.

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

Chen Yong briefly reported the situation and finally said, "How to deal with the tail behind the car?"

In the 128th Regiment, in the office of the leader Zhang Ting, he discussed with several cadres in the group’s team’s next training arrangements.

Suddenly, Zhang Tuan suddenly stood up and said loudly: "What did you say? Did that kid run over?"

Chen Yong said: "Yes, we ran all the way from the station to the 128th Regiment, which was only 5 kilometers away. Behind the car, we followed a bunch of curious people. I suspected that Douyin, Kuaishou and other things would soon explode."

Zhang Tuan was stunned for a moment, and said a little distractedly, saying, "It's a bit interesting. It's the first time I heard of such a newcomer. No wonder as a recruit, one person can kill a group of drug dealers with one knife. It seems that this is reasonable. This kid is a cruel person!"

"What?" Chen Yong said in surprise, "He killed a group of drug dealers by himself, with a knife? Group leader, didn't you lie to me, are you?"

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

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

Those were all a group of desperate people, and their combat effectiveness was not inferior to them at all. Some were even comparable to special forces.

One person, with a knife, kill a group? Why does it sound like a joke?

Zhang Tuan came back to his senses and said aloud: "Don't worry about this. Anyway, just bring him here. As for the tail, the broadcast warning is that this is a forbidden area in the military region. They will not get close. Be careful not to scare the people. Just warn. In order to show respect, I will take all the cadres in the group to pick him up."

Chen Yong was stunned.

"Zhang Tuan led all the League cadres out to greet him. This scene is a bit big!"

Chen Ling didn't know that he had already been alarmed by Zhang Tuan and was still running forward step by step.

"One step, two steps..."

While running, Chen Ling's sweat continued to fall, and dazzling traces formed on the ground.

With such extreme strength off-road, it almost reached its limit, and the whole body felt like it was about to fall apart.

Because of the violent breathing, the lungs are about to vomit.

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

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

If Chen Ling had not signed in to obtain the ultimate off-road skills and further strengthened his body, he would have been unable to hold on.

Suddenly, a crisp reminder sound came from Chen Ling's mind.

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

Chen Ling was stunned for a moment and was overjoyed.

"It's actually there, sign in!"

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

"Damn it!"

Chen Ling, who was originally very excited, almost fainted.

He is already at his limit, and he has broken his physical limit again off-road? How can this be done!

In addition, what is the future genetic constitution?

Can it be changed in human genes? Make the body feel like it has superpowers?

The first thing that Chen Ling thought of was various genetic research and transformations in science fiction films.

However, this is what I thought about later.

Chen Ling couldn't help but complain in his stomach: "System, are you playing with me? You didn't see that I'm almost as tired as a dog now? And I even asked me to break the limit again. Do you really think I'm made of iron?"

The system prompted quickly: "This is the physical potential of the future Soldier King, which can be equated with 4 times the physical fitness of ordinary people. The host can choose to perform now or delay."

"This is OK... but as for breaking the limit again, I can only talk about it when I reach the 128th regiment."

Chen Ling's eyes lit up!
Chapter completed!
