I Was Reborn in Another World, But I Awoke Inside a Corpse

Chapter 161: The Seed of a World

The breeze that morning was unusually calm—neither divine nor foreboding. Just wind. Ordinary, honest wind.

Isaac stood on one of the higher balconies of the elven palace, looking out over the treetop horizon. The World Tree pulsed with slow, restored life beneath his feet. But his focus wasn't on Yggdrasil.

It was on what came next.

The system flickered softly in his mind.

[Skill Selection – Level 89 Milestone]Choose 7 new skills from randomized options.

Seven options hovered in front of him like phantom windows. S-rank blades of lightning, EX-rank firestorms, ancient enchantments tied to stars. But Isaac's eyes didn't linger on power.

He chose purpose.

Two windows glowed brighter as he made his selection.

Skill Chosen: [Teleport – Rank S]Skill Chosen: [Worldseed Core – Rank S+]Remaining options dismissed. Skill slot availability preserved.

The moment he confirmed, the system responded like a second heartbeat.

[Teleport – Rank S]Instantly transports the user to any location within line of sight or to a previously marked coordinate.– Range: Unlimited if marked.– Cooldown: 3 seconds.– Passengers: No limit, so long as physical contact is maintained.– Mana Cost: Scales with distance and mass moved.

Isaac blinked once.

Then smiled faintly.

"No more running. No more borrowed ground. This one's mine."

Later that day, Sylvalen and Lira found themselves summoned to the courtyard garden where Isaac waited beneath the breeze-carved statue of a forgotten hero.

Sylvalen wore her soft robes today, all silver-green and moonlace. Lira had a pastry in one hand and dirt on her boots, clearly dragged away from some kind of rooftop mischief.

"You called?" Lira asked, raising an eyebrow. "New demon? God tantrum?"

"No," Isaac said simply. "Something better."

He held out his hands.

"I want to show you something. Something no one else will ever see unless I choose it."

Sylvalen tilted her head, sensing something deeper behind the words. "You've made a decision."

"I've made a world."

He activated the first of his two new skills.

[Teleport – Rank S]Target: Internal Anchor – [Worldseed Core]Requesting passenger transfer...Accepted.

The world folded.

And they were gone.

—

The transition was quiet.

They reappeared on a grassy plateau surrounded by a massive lake of mirrored water, distant silverwood forests, and hills bathed in starlight—even though no sun shone above. The air was crisp. Calm. Saturated with a familiar signature.

Isaac's.

Sylvalen turned slowly, her sharp blue eyes widening. "This mana... it's bonded. Alive."

Lira took a deep breath and blinked rapidly. "I've never seen terrain like this. Wait—this isn't just a spellfield, is it?"

"No," Isaac replied softly. "This is my [Worldseed Core]. A soulbound domain that exists entirely inside me."

He turned his palm upward. The earth responded.

A crystal tower rose in the distance. Trees rearranged themselves into a winding garden path. A glimmering flame appeared and gently hovered above the grass beside them.

"I control everything here. The ground, the shape of the land, even the way the sky looks."

He looked to them both.

"This world is permanent. Private. I can build homes here. A library. A forge. A farm, even. I can train, rest, hide, or fight."

Lira whistled. "You made your own country."

Sylvalen approached a tree and touched its leaves. Her voice dropped. "No. He made a future."

—

They wandered together.

Isaac shaped the terrain as they walked—a footbridge across a waterfall, a meadow that curved just enough to catch the light, a wind that carried no dust.

He summoned five Phantom Legion weapons and let them orbit lazily in the air. Their speed, control, and accuracy were flawless—amplified by the perfect synchronization of his will and the world.

Later, he created a lakeside firepit and summoned food directly from soul-sourced energy. Fruit, bread, even warm tea.

They ate in silence.

Because there was nothing more important to say than what already surrounded them.

—

When dusk arrived, not from time but because Isaac willed it, the lake turned glassy. Motes of warm light floated upward like fireflies. Lira lay flat in the grass, arms folded behind her head.

"You could bring people here. Resettle whole villages if you wanted."

"I could," Isaac said. "But this isn't for everyone."

Sylvalen sat beside him on the stone step of the pavilion he'd conjured. "Then who is it for?"

He looked at her.

"Us."

Her gaze softened.

Lira rolled onto her side, propped up on an elbow. "You're serious."

"I always am."

He looked toward the starlit sky.

"I'm tired of building everything for someone else's war. If I have to fight for the world… then I want a place where I'm allowed to live in it, too."

Sylvalen smiled. "Then this is not just your soul. It's your answer."

Isaac nodded once.

"This is what I'll protect."

—

That night, as the flame by the lake burned low and the two women he trusted most drifted into quiet, dreamless sleep beneath the stars of a sky that belonged only to him…

Isaac remained seated.

He didn't speak.

He didn't move.

He simply sat—and watched the world he'd created breathe.

Not in silence.

But in peace.
