I enlisted four times! My former unit blacklisted me.

Wu Hanfeng lay on the hospital bed sighing, occasionally touching the spot where he had just been given an injection.

"I think that little bastard Lin Xiao just doesn't like me and is deliberately getting revenge on me."

"This needle prick feels like an old lady embroidering, it hurts so much."

"Did he use a thicker needle?"

He was alone in the ward at that moment, and it was quiet.

Chen Zhiyuan and the others returned to their company.

Wang Erniu went to busy himself with cooking for the soldiers.

Lin Xiao changed the dressings for another patient.

He was left alone in the hospital room, bored and with no one to talk to, and suddenly he felt quite lonely.

Suddenly I remembered there's another system I can bother.

"system."

[Yes, host.]

"You said before that the physique enhancement fluid could only be used when one breaks through their limits. I've already fused it twice, so there are three more times left, right?"

Yes, the progress is 40%. Based on the host's fusion speed, it is estimated that there will be three more breakthroughs.

Wu Hanfeng tried to ingratiate himself, saying, "Since there are only three rounds left, can we try another method?"

"If I get dizzy again, Chen Zhiyuan will probably tie my feet up."

[Host, have you carefully read the system prompts before?]

"What hint? Is this even possible?"

[When using the fusion-enhancing liquid, pushing your limits isn't limited to running.]

Any form of physical training can trigger a breakthrough.

Wu Hanfeng was completely stunned!

"Wait a minute, say it again?"

Simply put, any sport that pushes you to your physical and mental limits is acceptable.

Wu Hanfeng was as if he had done his best to answer a math test, only to be told by the proctor that it was just a scratch paper.

Oh shit!

"Why the hell didn't you say you could do all this sooner?!"

[This system has already issued a notification.]

Wu Hanfeng: "..."

If he had known there were other ways, would he have fainted twice while running under the scorching sun on the playground?!

He was still on tenterhooks, busy playing guerrilla warfare with Chen Zhiyuan.

The system then told him...

Push-ups, pull-ups, and squats are all fine!

Fine, I guess I'll just have to accept my bad luck.

However, we need to confirm this next.

"Do other projects also require pushing yourself to the point of seeing stars and fainting in order to break your limits?"

Not necessarily. As long as the training intensity exceeds the normal frequency and speed and endurance are greatly enhanced, activation is possible.

[You fainted twice because your cardiopulmonary function is weakest, your lung capacity is small, and high-intensity aerobic exercise can cause temporary insufficient oxygen supply to the brain.]

Wu Hanfeng was immediately overjoyed.

"So, for the next three times I do push-ups, squats, or pull-ups, I don't have to worry about fainting?"

[It can only be said that compared to running, these methods have less impact on the cardiopulmonary system and are unlikely to cause brain hypoxia.]

Wu Hanfeng was still basking in the joy of being able to experience things in a different way.

"That's great, wait for me to get back..."

【but.】

Wu Hanfeng's smile froze instantly.

Even with the system, why is your speech still slurred?

It's so bad it makes you feel like you can't catch your breath.

The difficulty will increase significantly in the next three attempts.

As your physique improves, your personal limits also increase. What might have previously triggered your limits with the same training volume is now likely just a warm-up.

These words completely shattered Wu Hanfeng's spirits.

"You mean, I used to get dizzy after three kilometers, but now I need to go ten?"

That's roughly it, but the actual situation might be more complicated.

To put it simply, you might have felt so uncomfortable during practice that you might have fainted.

[Right now, it's very likely that I've reached the point where I feel like I'm about to die, and I can only hold on a little longer.]

Wu Hanfeng: "Will I still get dizzy so easily later on?"

[It's highly unlikely. As your body's threshold increases, you will remain conscious under the same extreme conditions.]

Moreover, you can clearly perceive the entire breakthrough process, including the tearing and restructuring of muscles, and you can clearly feel the surge of power.

Wu Hanfeng finally heard some good news.

As long as you don't get dizzy, it's fine.

Although I no longer feel dizzy, the breakthroughs ahead will be even more difficult.

It's hard to say whether running or physical training is more likely to trigger it, or how uncomfortable it is.

However, he completely gave up running.

Chen Zhiyuan and the other two were watching him closely. If he caused any more trouble, he would be out of a job in the army.

That means it can only be push-ups, squats...

These are more likely possibilities; after all, he trains every day in the army, so who would notice him?
