Strongest Existence Becomes Teacher-Chapter 212: If It Broke, I’ll Rewind It

Space was silent once more.

Where a planet had existed only moments ago, there was now nothing but drifting debris, glowing fragments of molten rock, and expanding clouds of cosmic dust slowly spiraling apart under the pull of twin red suns.

Zane and Eirenyssa floated calmly in the void.

A transparent barrier of layered divine mana surrounded Eirenyssa, shielding her from radiation, heat, and vacuum. Zane, on the other hand, stood without any protection at all, his coat drifting gently as if space itself refused to touch him.

Eirenyssa stared at the emptiness.

The planet... was completely gone.

Fragments the size of mountains glowed red as they cooled, forming long burning trails across space.

Suddenly—

A translucent holographic window unfolded in front of Zane.

Blue light flickered.

Text appeared.

[That was diabolical, boss.]

Eirenyssa blinked.

"...?"

Zane glanced at the screen and nodded lightly.

"Yeah," he said calmly. "That was diabolical."

Another line appeared beneath it.

[The gods of that realm are definitely going to panic now.]

Zane smirked faintly.

"Good."

He looked toward the expanding debris field, eyes narrowing slightly.

"But now it’s time to fix this planet."

Eirenyssa stiffened.

"...Fix it?" she asked carefully.

She looked again at the void where an entire world had just been erased.

"My lord... what do you mean by fixing the planet?"

Zane folded one arm, resting his chin on his knuckles as if casually thinking about rearranging furniture.

"Well," he said slowly, gaze drifting through the scattered fragments, "this planet was around four times the mass of Orimund."

He pointed toward the twin suns in the distance.

"And roughly two-point-two times Orimund’s gravity."

Eirenyssa listened quietly.

Zane continued.

"That makes it extremely important in this binary star system. Its gravitational field stabilizes the asteroid belts."

With a flick of his finger, a projection appeared — countless space rocks orbiting chaotically around the system.

"It acts like a shield," Zane said. "Redirects most incoming asteroids away from Orimund."

The projection shifted.

Without the planet’s mass, the orbits destabilized instantly.

Rivers of red warning lines flooded the display.

"Without it," Zane went on, "Orimund would experience repeated extinction-level impacts."

Eirenyssa’s breath caught.

"Especially," Zane added calmly, "from the debris created by the planet’s own explosion."

He looked at the massive field of glowing fragments still spreading outward.

"Kind of ironic."

Eirenyssa swallowed.

"...So what will you do, my lord?"

Zane straightened.

His deep purple eyes reflected the ruined system.

"I’m going to return it," he said simply.

Eirenyssa froze.

"R-return it...?"

Zane rolled his shoulder once.

"As it was."

He raised his hand toward the cosmic debris field.

"Shape, mass, orbit, core structure — all of it."

A faint smile formed on his lips.

"Would be troublesome if my entertainment caused a mass extinction."

Behind him, the holographic window flickered again.

[Boss... you’re really treating planets like broken furniture now.]

Zane chuckled.

Eirenyssa looked at the endless debris field, glowing fragments still drifting through space.

Then she turned toward Zane.

Curiosity slipped through her exhaustion.

"My lord... how would you even fix a planet like this?"

Zane glanced at her.

The look he gave made her feel like a confused puppy that had just asked why the sky was blue.

He smirked.

"I’m going to turn back time."

Eirenyssa froze.

"...Turn back time?" 𝕗𝐫𝚎𝗲𝘄𝐞𝕓𝐧𝕠𝘃𝕖𝐥.𝐜𝚘𝚖

Her eyes widened slowly.

"You... can do that?"

Before Zane could answer, a translucent holographic window unfolded from his technowatch and floated in front of her face.

Blue light flickered.

[Eirenyssa, you really shouldn’t be surprised at the things our boss can do.]

Another line appeared beneath it.

[He can do anything.]

Eirenyssa stared at the glowing screen.

Then at Zane.

She nodded slowly.

"...I see."

Even so—

Her expression remained completely stunned.

Zane looked at the drifting debris for a moment.

"Hm... turning time back on a scale this large might force me to use ten percent of my power," he muttered.

"...Maybe more."

He thought for a second.

"Let’s try twenty percent."

Space remained silent.

Nothing visibly changed.

Yet everything had changed.

Zane stood exactly the same, his appearance untouched—but at that instant, twenty percent of his in universe strength was released into the world.

Eirenyssa’s body reacted before her mind did.

Her heartbeat spiked violently.

A primal fear flooded her veins, something engraved into existence itself—the instinct meant to warn beings when they stood before something far beyond them.

Her skin broke into sweat.

The droplets didn’t fall.

They evaporated instantly, sizzling into mist the moment they formed.

Her breathing became uneven.

Her knees trembled.

Zane turned his head and noticed her condition.

"...Oh."

He blinked once.

"My bad. I’m just too strong."

He thought briefly.

"I think ten percent will be enough."

Zane extended his palm toward her.

A translucent barrier formed instantly around Eirenyssa, isolating her from the pressure.

The fear vanished.

The heat stopped.

At the same time, Zane adjusted his presence—his power settling down to ten percent.

In his open palm, a dark-green magic circle bloomed.

Intricate patterns rotated within it, layered with countless runes. One by one, dozens—then hundreds—of smaller magic circles manifested around the main formation, orbiting in perfect synchronization.

As the spell stabilized—

tick... tock...

A sound echoed through space.

There was no air.

No medium.

Yet time itself can be heard.

Zane spoke calmly.

"Time Magic: Planetary Reversal."

The magic circles detached from his palm and drifted forward.

As they moved, they expanded—larger... larger... until they dwarfed mountains, until their runes stretched across space like celestial machinery.

Zane slowly raised his hand.

Palm open.

Then he rotated it in a slow anticlockwise motion.

The universe obeyed.

Fragments of shattered continents trembled.

Debris began to reverse its path.

Rocks that had been hurled millions of kilometers away shuddered... then curved back.

Shattered crust plates pulled toward one another.

Even dust reversed its dispersion.

The destroyed planet’s remains started returning—piece by piece—drawn backward through time itself.

Slowly, the scorched and molten debris began pulling together.

Burned fragments that had once been continents reversed their violent trajectories, sliding back into place as if guided by an unseen hand. The blinding explosion that had destroyed the planet moments earlier began to unfold in reverse—light collapsing inward instead of expanding.

Fire retreated.

Shockwaves folded back into silence.

Molten rock flowed upward, climbing back into fractured crust instead of spilling outward. Deep cracks sealed themselves, tectonic wounds knitting together as if they had never existed.

The planet’s core stabilized.

Its shattered mantle reformed.

Atmospheric particles returned, swirling back into orbit, rebuilding layers of sky that wrapped the world once more. Clouds took shape, winds resumed their paths, and gravity settled into balance.

What had been nothing but ruin slowly became whole again.

The lifeless, frozen planet reformed completely—

exactly as it had been before its destruction.

Zane lowered his hand.

He looked at the restored world and smiled faintly.

"...Done."

Zane turned away from the restored planet.

"Now," he said calmly, "to the god realm."

Eirenyssa blinked.

"...God realm, my lord?"

Zane nodded.

"Yep."

He sighed lightly, rubbing the back of his neck.

"You don’t know this yet, Eirenyssa, but gods tend to act like third-grade villains in novels and manga ."

He tilted his head, mocking.

"That Lilithara is definitely running back right now, crying to her higher-ups about what happened here and instead of a wise and calm gods they will act like–"

He raised his hand and exaggerated an expression.

"..Uh How dare he challenge god’s authority...?"

His lips curved upward.

"Better dispose of them now, before they become a nuisance."

---

Far away—

Within the god realm.

A vast chamber drowned in darkness.

Lilithara knelt on all fours upon the cold divine floor, her body trembling as she reported everything she had witnessed. The air itself felt heavy, crushed beneath unseen authority.

Figures sat beyond sight, concealed within shadows.

After a long silence, one voice echoed through the chamber.

"How dare he challenge god’s authority...?"

Another voice followed, sharp and furious.

"He must die."

A third spoke more cautiously.

"But the three great leaders have gone once again to Everion for their meeting. Can we truly act without their permission...?"

The chamber fell silent once more.

And somewhere beyond that darkness—

something dangerous had begun to stir.
