Realm, the Peak of Human Physical Potential

After the muffled thud, Lei Long cast a quiet glance at the twisted, ruined punching post, his body trembling.

He didn't dare to speak, shrinking back slightly; the tough-guy aura he had displayed while teaching was completely gone.

The students standing in a row also had their eyes twitching, fighting the urge to wince, but the terrifying pressure brought by Lin Fei kept them from making a move.

"Is that thing made of iron? She wrecked it with one punch?"

"That has to be at least a thousand pounds of force, right? Is the head coach even human?"

As the group engaged in intense brainstorming, Lin Fei swept her gaze over them.

In an instant, they straightened their postures, standing tall with eyes wide as bells and expressions resolute.

"What Lei Long taught wasn't great, but don't blame him."

"He said there was nothing to say, but the truth is, he couldn't explain it himself."

"He's just purely brainless, but he's not a bad person."

"As compensation, each of you will receive one medicinal bath session, and the cost will be deducted from Lei Long's salary."

After she finished speaking, the aura around Lin Fei slightly receded.

Upon hearing that his pay would be docked, Lei Long opened his mouth, but after a quick glance at Lin Fei, he silently shut it again.

The students also relaxed, beginning to whisper and discuss among themselves.

"What is a medicinal bath?" Lin Ye looked toward Yan Yi.

Yan Yi took a quiet peek at Lin Fei and whispered, "It's soaking in a barrel of medicinal liquid; it can treat physical injuries."

"It's not cheap—three thousand yuan a session, almost as much as the tuition. Coach Lei's salary for the next half-year is going to be wiped out."

"But don't use it yet. Wait until you've mastered the basics of the fist technique; that's when it's most cost-effective."

Lin Ye nodded in understanding. "Coach Lei is a righteous man."

"Clatter—"

Lin Fei pulled over a massive mobile blackboard from the side and used chalk to draw a large diagram of a human body.

Lin Ye looked over; the head coach's drawing skills were excellent, perhaps even clearer and more precise than those of a professional artist.

Inside the human silhouette were segments of the spine, with thin lines extending outward to connect to every part of the body.

"Tap, tap."

Lin Fei tapped the blackboard with her pointer, and the students' gazes immediately shifted toward it.

"Today's lesson has two main parts. First, I will re-explain the realms of the fist technique."

"Second, I will help you sort out your fist force, which serves as compensation from Lei Long."

After speaking, the black pointer poked at the spine of the human diagram.

"The hallmark of the first level of the Soul Whale Fist is 'Qi sensation like a rope'."

"As the name implies, when the hot sensation transforms into Qi, besides feeling a change to a warm, cool sensation, you can also feel this Qi rotating around the spine as an axis, tightening the meridians throughout your body."

"This feeling of being taut all over is the most intuitive physical sensation of having mastered the first level."

As she finished, Wei Qian, standing at the head of the first row, nodded secretly.

In reality, his physical fitness had long met the requirements, and he had experienced this feeling of being taut all over.

However, he hadn't developed the Qi sensation; this wasn't something one could master without guidance, at least not for him.

After a pause of a few seconds, Lin Fei continued, moving the pointer along the lines extending from the spine.

"At the very beginning, this rope-like Qi sensation can only affect the back."

"The practice of the first level is to guide this Qi along the meridians to the limbs, eventually reaching the point where the Qi penetrates the ten fingers."

"Force follows Qi; once you reach the point where Qi penetrates the ten fingers, you have mastered the force."

"Once you exert force, the power reaches your fingertips; you could pierce through ordinary wooden boards with a single jab."

As she spoke, Lin Fei extended her index finger and pressed it lightly against the stone blackboard, leaving a small hole behind.

"Once the Qi penetrates the ten fingers, the Soul Whale Fist has reached the second level."

"The practice for the second level is actually quite simple: 'Refining Qi into a Python'."

"The first level's 'Qi sensation like a rope' is about 'tightness', but if it's too tight, it's prone to snapping."

"Therefore, you must refine the Qi sensation to be both tight and sinewy, ensuring it doesn't break, as if you are cultivating a giant python within your body."

"This step requires patient, grinding effort. You gain a day's worth of progress for every day you practice; it cannot be achieved without hard work."

"When you clearly feel a sense of fullness emerging from within your body, it signifies that your physical potential has been released, marking your mastery of the third level of the Soul Whale Fist."

Lin Ye stood quietly in the back row, feeling a bit puzzled.

A sense of fullness?

He remembered having that exact feeling back when he added points to his Strength attribute.

Does this mean that while Potential Points are being added, they are also improving physical aptitude? Or perhaps, stimulating potential?

"Knock, knock."

The pointer tapped lightly against the blackboard, and Lin Fei adjusted her glasses.

"Once you practice the Soul Whale Fist to the third level, your physical fitness will approach the peak of human potential in every aspect."

"And the practice of the third level is, in fact, the process of allowing you to completely reach the limits of the human body."

"However, the specific methods for training the third level involve certain secrets, so it is not convenient to discuss them here."

After she finished speaking, her gaze swept across the room, and Wei Qian raised his hand.

"Head Coach, the human limit varies from person to person, right?"

Lin Fei did not deny it, "That is correct."

"Under normal circumstances, as long as one can reach the third level, they will have a punching force of at least three hundred kilograms."

"But the upper limit of the third level is hard to say; the lowest might be under four hundred kilograms, while those with innate talent like Lei Long can approach or even exceed five hundred kilograms."

Wei Qian's pupils trembled. Three hundred kilograms—that was the standard for a gold-medal boxing coach certified by the Federation!

In the entire boxing league, there were no more than three hundred boxers who could reach this level!

Reaching the level of a gold-medal coach was already a realm difficult for ordinary people to touch; even the gap between them and the level of a boxing champion was not that large.

And five hundred kilograms—although there were no clear records, he feared that few of the current boxing champions in the league could reach that level.

Even though he had already witnessed Lin Fei's terrifying strength with his own eyes, he still found it somewhat difficult to accept for a moment.

After all, this was completely challenging, if not destroying, the perceptions he had built up over the past twenty-some years.

However, he adjusted quickly, even beginning to feel a bit excited.

Ancient Fist Arts—this was a completely different field from boxing or even modern combat!

Leaving the modern martial arts gym in the first place was exactly for this!

Now that it had become reality, he should be happy!

In a daze, he felt as if he had touched the truth of this world.

A real world, completely different from the surface reality.

Behind him, Lin Ye was similarly excited.

Approaching the peak of human physical potential in every aspect—as someone who had nearly completed the Ozaki Eight, he knew better than anyone how monstrous the physical fitness of such a person was.

Because he himself had once been one of them.

Approaching the peak of human physical potential in every aspect did not mean approaching world records in every physical category.

Rather, it meant reaching a point in every physical domain that ordinary people could not reach through conventional training, hence the term "peak."

The closest comparison would be a decathlete; their performance in any single event might seem "ordinary" compared to world records.

But when these "ordinary" traits were concentrated in one person, they formed a desperate, impenetrable wall.

Beside him, Yan Yi's gaze was calm.

She knew the intensity of the third level of Ancient Fist Arts very well; her father was an expert at this level.

He could single-handedly fight a mountain tiger with a blade, and if fighting unarmed, a single punch would snap tendons and break bones; even seven or eight ordinary men armed with weapons would be no match for him.

But that was as far as it went; her family's martial art, the Spirit Thread Fist, was not as good as the Soul Whale Fist.

It was not just that the body-tempering effect was inferior, but also because the third level of the Spirit Thread Fist was incomplete, missing key components.

Therefore, even if she practiced to the peak, she could not reach the human limit, nor could she even come close.

She had signed up for the Whale-Kill Boxing Hall specifically to obtain the complete training method for the third level of the fist art, and to break through to the fourth level or even higher!

She touched her neck lightly; the centipede-like scar extended down to below her collarbone, aching faintly.

"Cough, cough."

"Boss, the confidentiality agreement."

Lei Long coughed twice, speaking up to remind her.

Telling the students that the punching force of the third level of the fist art could reach five hundred kilograms was already a violation.

Lin Fei pinched her earlobe, "It's fine, these are all borderline pieces of information; knowing them is fine."

She looked at the group, "Do not spread what I said today; it won't do you any good if it gets out."

In reality, even if it were spread, how many would believe it? Who had actually seen it with their own eyes?

The third level—how could the third level be that easy?

After the age of thirty, all physical functions begin to decline.

If one cannot reach the third level before this age, they can basically forget about it for the rest of their lives.

In reality, the third level is a hurdle; ninety-nine percent of people cannot pass it, and they won't pass it even if they practice for a lifetime.

Even some of the top boxers in the Federation, enjoying top-tier resources, are only able to compare to a third-level martial artist in the single aspect of punching force.

"Alright, that's enough talk about the realms for now."

"If you can reach the third level and sign a contract with the gym, you'll naturally learn about the information that follows."

Lin Fei took off her glasses, and her entire demeanor shifted instantly, becoming wild and uninhibited.

"So, the boring lecture ends here."

"Next, I will personally help you refine your fist energy."

Having said that, she took off her top directly and grinned, revealing two rows of white teeth.

"Take them off; it's going to get very hot in a moment."

Tossing her black coach's jacket aside, Lin Fei's wheat-colored upper body appeared in everyone's line of sight.

It wasn't bulky, but it was incredibly toned—a standard lean physique with a shredded, defined texture.

A delicate gold necklace around her neck held a silver oval pendant that looked like a locket.

"Coach... you're so flat," a round-faced female student remarked.
