The bald-headed observer saw this scene, and his pupils suddenly contracted to a dot, revealing a barely noticeable surprise in his eyes.

"This... this... this... is actually control perfected to the extreme!!"

Just now, Xu Ran’s punch forward plunged the bald-headed observer into extreme astonishment.

He was utterly shocked.

The entire person was in a state of disbelief.

Just now...

The golden trail appearing in the air, and only on that trail did the sound of sonic booms emerge, sufficient to indicate that at this moment, Xu Ran had already controlled the power in his fists to perfection!

It must be known.

No matter what kind of power, when within the body, it can be controlled, but once released externally, although still manageable, it greatly loses stability.

To achieve energy release solely along a singular trajectory requires terrifying control.

"However..." The bald-headed observer stared at Xu Ran, speaking out, "This is limited to the power within the fists; if it were other body parts, it might not have such a good effect!"

"Phew!"

Xu Ran retracted his fists, exhaled deeply, and also heard the bald observer’s words.

He did not dwell on the guess, mainly because the bald observer was right.

Currently.

The energy within his body, aside from being able to release through his fists, is sealed in all other parts.

If he wants to achieve this, he only needs to fully focus his control on his fists, without worrying about energy leaking elsewhere, as it stays unstable.

If his whole body’s seals were lifted, his control over energy surely wouldn’t be as smooth as now.

"This might be why other parts of the body are sealed, to perfectly experience the energy released from the fists!"

At this moment.

The senior apprentice observing Xu Ran’s trial also spoke.

"Thus, indeed, control over fist energy and cultivation of fist techniques can achieve twice the result with half the effort!"

The second apprentice also spoke in agreement and exhibited a tone of envy.

Being of the Black Flame Body, he specialized in physical cultivation, reaching extreme control over every cell of his body, but this process consumed countless years to achieve.

Yet Xu Ran, due to the Nine-Layered Giant Tower trial, mastered this at less than two years old!

"If I had known about this cultivation method back then, I’d have become a Great Power millennia ago!"

"Such a thing would never happen!"

The senior apprentice’s cold tone immediately shattered the second apprentice’s fantasies.

"Even if you knew this cultivation method, who could achieve it, sealing the whole body, leaving only the fists to harness Spiritual Qi?"

To accomplish this is beyond even the Great Powers, requiring very harsh conditions.

Firstly, the cultivation should not be below Great Power, next an absolute command over Sealing Skills, precise enough to seal only one place without harming the body.

Even the ever-knowing senior apprentice cannot find such an existence.

"Ha!" The second apprentice also realized this, "That’s true!"

As a specialist in physical cultivation, he knows how much darkness this training method can bypass.

And at this moment, all three held a common curiosity.

Who is the person appearing in the Nine-Layered Giant Tower trial checkpoint?

Is such a strange ability possessed by the bald-headed person or inherent in the Tower itself?

A moment of contemplation.

The three observers of Xu Ran’s checkpoint trial each harbored their own thoughts.

...

"If the seal is lifted, this can’t be achieved!" Xu Ran muttered watching the bald observer.

Though he had absolute faith in his talent, it was as such now.

Even if the bald observer lifted all seals of other areas, returning all energy, the entire body would engulf with energy, failing to reproduce the punch’s effect just performed.

Nonetheless, there’d be significant improvement compared to before.

"This is the significance of sealing other body areas!"

"To gradually control each part, enhancing control strength, thereby maximizing energy utilization!"

The understanding Xu Ran gained assured him of the bald-headed observer’s purpose — to teach him.

The bald observer seemingly didn’t hear Xu Ran’s muttering, simply nodded.

"Since you can control the power in your fists, next, mastering fist techniques is necessary!"

Suddenly, the bald observer seemed to transform into a refined teaching instructor.

"From the previous battles, it’s observable that your body harbors numerous energies coveted by others, their magnitude capable of outright crushing others to death, surely you’ve experienced many such feelings!"

"But this method only works against weaker opponents; what of those stronger than you?"

The bald observer’s inquiry plunged Xu Ran into deep thought.

Indeed.

Before entering the Nine-Layered Giant Tower, he’s always resorted to overwhelming energy against opponents.

No matter how strong the enemy, with the Immortal Sword Skill unleashed, they directly fell; the singular time he faced real danger was in aerial combat with an eagle high in the sky, nearly losing handhold.
