The male lead does not change

Xin Yuan was shocked when he heard the word "five kilometers".

As long as a person can absorb radiation energy into his body, he can become a radiation warrior. Such a person is generally in good health, but Xin Yuan is just an ordinary person.

When he was a child, he also did physical training under the guidance of his father, and more than once, with the help of his father, he tried to absorb radiation energy into his body.

However, he tried many times, but he couldn't absorb the radiation energy into his body. There were several times when Xin Qing specially guided the radiation energy into his body. It was fine that day, but the next day, he would find that the radiation energy in his body empty.

His body couldn't hold any radiation.

In this world, there are nearly ten percent of people, no matter how hard they try, they cannot become radiation warriors. They are born unable to absorb radiation energy into their bodies.

And such people are generally born with poor health, and surviving in an environment with more radiation will make them sick.

Xin Yuan was not as serious as them. He didn’t feel a thing or get sick after being exposed to radiation outside the city, but since he couldn’t become a radiation warrior and was just an ordinary person, everyone agreed that he was weak and his body was weak. Since then, his parents have never let him exercise every day.

They only hope that he can grow up in peace.

Xin Yuan's life after that was indeed quite smooth, but compared to those around him who could more or less absorb some radiant energy into their bodies even if they couldn't become stronger, he was much weaker with some radiant energy in his body.

Over time, everyone defaulted to his poor health.

In addition, the underground city is very crowded, the per capita living space is very small, and the public transportation is very developed...Xin Yuan basically has no sports opportunities.

He used to run on a treadmill with someone before, but after running less than two kilometers, he felt that his heart couldn't take it and he was about to die.

Now this person in front of him lightly asked him to run five kilometers? !

"What? Too little? It's okay, this is just a warm-up, and there will be other training next." Guan Chengfeng said.

Xin Yuan: "...No, there are too many!"

Guan Chengfeng: "..."

Guan Chengfeng stared at Xin Yuan for a while, and then said: "Go up and run first, and run as long as you can."

In fact, he asked Xin Yuan to run because he wanted to see Xin Yuan's physical condition - this treadmill is the latest civilian treadmill, which can monitor and record the user's physical condition while the user is running.

He knew that Xin Yuan was not in good health, so he didn't arrange a training plan right away, but let him run first, test his physical fitness and check his physical condition.

But he really didn't expect that Xin Yuan couldn't even run five kilometers.

Which organ of his is not good?Can it be cured?Medicine in this era is still very developed, because many exotic plants and animals can be used as medicine, and some medicines with particularly good curative effects have appeared.

Xin Yuan can definitely go and treat her well.

Guan Chengfeng regretted that he paid too little attention to Xin Yuan before, but at that time he was in great pain because of his serious injury, and he had a lot of things to do, so he really couldn't care about Xin Yuan.

Xin Yuan gave Guan Chengfeng a pitiful look, got on the treadmill, and started running slowly.

In the past ten years, let alone training, he didn't even walk much. When he started running, he always felt that his legs were a bit heavy.

In the dungeon, many people are actually like him.

Although most people can cultivate radiant energy, their strength generally stays at the first level, and there is no way to continue to break through.

Level [-] radiation fighters are not much different from ordinary people.

Under such circumstances, many people will completely give up cultivation after they are sure that they have no talent for cultivation.

How good is it to have free time to play games?Why do you have to practice so hard?The appetite will get better after practicing... Where did they get so much money to buy food? !

The food that people usually eat contains more or less radiation, and those who have absorbed radiation energy will not degenerate into ordinary people, but even so, those who neither practice radiation energy nor exercise their physical strength will still have poor physical strength. Not stronger than ordinary people.

There is no shortage of waste wood like Xin Yuan in the dungeon.

Xin Yuan got on the treadmill and ran without any skill.

Because he wanted Guan Chengfeng to admire him, he ran a little fast at first, so he started panting after only 100 meters, so he had to slow down. When he reached 500 meters, he already wanted to give up.

But that... seems like too little run?Xin Yuan gritted his teeth and persisted until 1000 meters...

Sweat was all over his forehead, his breathing was in a mess, and he finally stopped: "I can't run anymore..."

"Your physical indicators are very good, you can continue." Guan Chengfeng frowned.When Xin Yuan was running, he had been paying attention to Xin Yuan's physical condition.

Xin Yuan is an ordinary person, and his health is not very good. If he exercises too much, accidents may happen.

The result... Judging from the physical condition of Xin Yuan recorded by the machine, his body lacks exercise, his muscle mass is low, and his cardiopulmonary function is poor, but his body organs are not bad.

It can be said that as long as he persists in exercising, his body will become stronger!

Even if Xin Yuan can't absorb radiation and become a radiation warrior, having a strong body is good for him.

Anyway, it can increase life expectancy, can't it?

"I'm very tired..." Xin Yuan looked at Guan Chengfeng pitifully. Seeing that Guan Chengfeng's face didn't change, he couldn't help but said, "I'm not here to be an assistant? Why do I have to run?"

He doesn't want to run!

"You are here to be an assistant. But since you are my assistant, you have to listen to me." Guan Chengfeng said.

"Guan Shao...he has never run like this before..." Xin Qing felt sorry for his son.

"This treadmill has supporting body monitoring. If his body can't stand it, the machine will stop automatically." Guan Chengfeng looked at Xin Qing, "I won't hurt him, but you... are you sure that this pain will not hurt you?" Don't let him suffer?"

Xin Qing fell silent, hesitation appeared on his dark and rough face.

He remembered the video Guan Chengfeng played to him before.

Originally, he had always thought that it would be good for him to leave a house for his son, help him find a simple job, and let his son pass the rest of his life normally, but now it seems that it is not easy to pass the rest of his life normally.

"And you," Guan Chengfeng said again, "Do you want to break through and become an intermediate radiation warrior?"

"What? Can I break through?" Xin Qing was surprised.He is only a third-level radiation fighter, and he is still too weak after all.

But there is a big difference between the third level and the fourth level, and it is very, very difficult to break through. He is now in his 40s, and logically speaking, there is absolutely no possibility of breaking through.

"Of course you can," Guan Chengfeng said, "If you practice with me, you will be able to break through in a short time."

Guan An was not very serious when he was practicing, he was only a third-level radiation warrior, and now he is only a third-level fighter, so it was just right for Xin Qing to practice with him.

The most important thing is...his cultivation method was discovered by himself, which is different from others.

As long as you tell Xin Qing his cultivation method, it is very difficult for Xin Qing to become a strong man, but it is still no problem for him to break through from level three to level four.

As for himself...

In the previous ten years, he improved his cultivation method that he had figured out when he was young.

Due to time constraints, the improved physical strength had to catch up first, and efforts had to be made to fit this body.

If he can't use this body smoothly... all his fighting skills are there, and his body can't keep up with the final defeat, it would be too miserable.

"Will it be too troublesome?" Xin Qing was full of excitement, but also worried that it would trouble others.

"I'm looking for someone to practice with. Come on, let's play a game first, let me see your strength." Guan Chengfeng said.

He wanted to know about Xin Qing's situation, and moreover, he needed to get used to this newly acquired body through fighting.

Guan Chengfeng has already tidied up Guan An's house, and now there is nothing in the living room. This area of ​​about [-] square meters has become a small martial arts arena.

After Xin Qing agreed, Guan Chengfeng did not delay, and directly moved his hand.

Although Xin Qing stayed outside the city for a long time these years, he always took care of his plantation in the safe area, and rarely fought with strange beasts, and occasionally fought, and those strange beasts were also very weak.

His fighting skills were poor, so...even if Guan Chengfeng didn't quite adapt to his current body, he still beat Xin Qing.

Not only that, because he was not very used to his body and could not control his strength, Xin Qing was also injured by him.

Even though he had stopped as soon as possible, Xin Qing's face was still bruised.

Xin Yuan: "..." This man is too scary!How did you beat his father up? !

If he doesn't run well, will he be beaten?

After wiping his face, Xin Yuan continued to run, completely unaware that his makeup was wiped off just now.
