Chapter 8: The Might of the World-Shaker, Use with Caution!

Chapter 8

Everyone’s ability to harness their own strength varies, so the power they can unleash in specific situations differs as well. No one can maintain full force at all times, let alone deliver an ultimate strike with one hundred percent of their physical power.

For those without professional training, a normal punch typically releases only about 30% to 40% of their strength. Through training, one can improve muscle recruitment to increase explosive power. This scientific principle holds true even in this otherworldly realm.

Take Yu Le, for example, who had previously reached the second tier of the Rock Realm. Under normal conditions, he could barely muster a punch delivering force equivalent to sixty or seventy jin (roughly thirty to thirty-five kilograms). This threshold depends on both physical and emotional factors. Naturally, anger amplifies punching power—that’s the commonly known adrenaline surge.

At this moment, Yu Le employed the Shock Domain power, his muscles taut and compressing with strength. With a single punch, a sonic boom echoed through the air.

His eyes lit up as he looked at his fist, which casually produced a sonic boom. “No special technique needed—Shock Domain power concentrates all my strength into a single point for perfect force!”

Producing a sonic boom means his punch reached or exceeded the speed of sound. In terms of force, that equates to about 173.47 kilograms. A practitioner at the second tier of the Rock Realm could theoretically unleash such force in an ultimate strike at their limit. But even Yu Le, who had been at that level before, had never achieved this. And certainly not with a sonic boom as thunderous as a clear sky cracking with lightning.

He wasn’t sure how strong his physical body truly was now, but that punch was only a basic use of Shock Domain power. He knew he could compress more.

Continuing to push, Yu Le tested his limits until his face flushed red, veins bulging on his charging right arm as if about to burst.

“Ah!”

Yu Le shouted and struck the wall.

He didn’t actually touch the surface—his fist stopped about twenty centimeters short.

Bang!

The wall trembled, cracks radiating outward from the impact point like a spiderweb, causing the entire house to shudder slightly.

Still stunned, Yu Le heard the neighbor on the other side angrily pounding the wall and shouting, “Yu Le, what the hell are you doing in broad daylight? Are you trying to get yourself killed?”

The soundproofing of these housing units was poor to begin with, and Yu Le’s punch had terrified the widow next door so much she nearly wet herself. Anyone unaware might have thought an earthquake struck.

Embarrassed, Yu Le responded, “Sorry, Sister Zhou. My wife ran away, and I’m just feeling down.”

Silence came from the other side.

Sister Zhou thought, I really deserve this.

“Well... keep it down, okay? Don’t do anything reckless. If you can’t sleep at night, I’ll leave my door open. Feng Jiujiao doesn’t care about you, but Sister Zhou does.”

Yu Le was speechless.

Besides, he wasn’t particularly interested in women himself. After transmigrating to this world and living daily with a wife who was practically a celestial beauty, the neighbor’s plump lady, weighing over three hundred jin (about 150 kilograms), held no appeal.

The small commotion settled, and Yu Le smiled with satisfaction at his handiwork.

But then his right arm cramped suddenly.

“Damn, a cramp...”

No one can maintain peak form indefinitely—not even in the Rock Realm.

Forcing his Shock Domain power to compress his strength came at a cost: his entire arm felt numb and painfully sore.

Still, sparks flickered in his eyes. “Double. Now, using Shock Domain power to compress my own strength, I can unleash twice my limit!”

This was Yu Le’s personal limit, not the absolute limit of Shock Domain power.

Besides being able to release twice his physical strength in a single burst, attacks empowered by Shock Domain also carried area effects.

Like the wall in front of him: centered on the punch’s impact point, Shock Domain power radiated outward about a meter in radius.

This was the essence of an earthquake!

Shock Domain power originated from the Tremor-Tremor Fruit of the One Piece world, adapted and renamed to fit this world’s battle arts, but its nature remained unchanged.

As a Paramecia-type Devil Fruit, Whitebeard’s Tremor-Tremor Fruit was dubbed by Fleet Admiral Sengoku as “the power to destroy the world.”

Compared to Whitebeard’s ultimate move in One Piece—“Quake, Break, Sky Split, Earth Shatter,” capable of triggering tsunamis—Yu Le’s Shock Domain power was like a raft in a small creek versus an aircraft carrier.

A young Whitebeard?

Looking at his still twitching arm, Yu Le reflected, “Whitebeard rose to Yonko status thanks to the Tremor-Tremor Fruit, wielding world-shattering power, but at a heavy price. Excessive use severely damaged his body, and in old age, his health declined rapidly.”

“Whether it’s the Tremor-Tremor Fruit or the Shock Domain power I wield, both have such side effects. Without a robust physique, one can neither adapt nor fully utilize this power.”

The greater the strength, the greater the backlash. Shock Domain power is potent but must be handled with caution!

This was Yu Le’s warning to himself after mastering the Twin Heavenly Arts.

Possessing twin Heavenly Arts marked him as having extraordinary potential, but relying excessively on battle arts’ powers at the cost of irreversible side effects would be a loss far greater than any gain.

Having grasped the general effects of his two major battle arts, Yu Le’s preparations were complete.

Of course, the role of Heavenly Arts wouldn’t end here. Further power discoveries would require raising both his realm and his vision.

With two great Heavenly Arts at his side, after a grueling half-month, Yu Le was ready to begin his plan to save his daughter!

The afternoon had come, but driven by urgency, Yu Le wasted no time. Traveling light, he headed directly toward his destination:

The Demon Hunting Association!
