Ultimate Magus in Cultivation World

Tian Lei stretched his new limbs a little, getting used to the different look, the different aura, the different presence he now carried.

"Alright…" he muttered, tapping his cheek with one finger. "New face, new eyes, new beast… now what should I do?"

He sat down beside the lake, the water rippling gently as if waiting for his next move. With a flick of his wrist, the Seven-Star Radiant Essence Core floated out of his storage ring, spinning slowly above his palm. Each stripe glowed like a trapped constellation.

He stared at it, thinking.

"Hmm… I could use magic to transfer the bloodline into my unborn egg," he said, rubbing the back of his neck. "But I don't even know what effect it'll have. Could make it stronger… could explode it… could turn it into a chicken. Hard to say."

He sighed, leaning back on his hands.

"I need some guinea pigs… to test it… before using it on myself," he grumbled. "which means I need more essence cores and some human subjects, though they need to be unawakened too"

"I cna't just go around and experiment on kids, well atleast innocent one, since its wuxia I might find some young masters type" he mumbled nodding to himself, "okay I will do it"

His gaze drifted to the sky.

"…Well, I could hunt some Essence Cores first."

He stood up, cracking his neck.

"Only Spirit Rank monsters drop Essence Cores, and my power is already sitting at the peak of Spirit Realm. So I guess…" He shrugged casually. "…I'm good to go."

He tightened his fist, sparks of black lightning dancing across his knuckles. The lake surface shook from the pressure.

Without another word, Tian Lei launched into the air. His body shot upward like a spear, black thunder cracking behind him as he vanished into the clouds.

Below him, the vast wilderness stretched endlessly—mountains carved like dragon spines, forests so dense they swallowed sunlight, rivers that shimmered with spiritual energy.

And scattered across it all… countless monsters.

Everywhere he looked, he could sense them—creatures radiating aura levels ranging from early Spirit Rank to peak Spirit Rank. Perfect hunting grounds.

Tian Lei's eyes lit up, a predatory grin spreading across his face.

"Looks like this place is crawling with monsters carrying Essence Cores," he said, closing his hands together like he was praying for good business. "Perfect."

He descended toward the first cluster of powerful auras, black lightning spiraling around him as the air cracked from his speed.

Time to hunt.

He hit the forest canopy like a falling thunderbolt, landing without slowing down. Trees snapped and splintered as shockwaves rippled out from the impact, scattering birds and lesser beasts in every direction.

Three Spirit Rank monsters lunged at him instantly—drawn by his aura, driven by instinct.

A Steel-Tusked Rhino.A Crimson-Fanged Ape.A Shadow-Striped Panther.

All early Spirit Rank. All confident. All wrong.

Tian Lei didn't even blink.

"Alright, let's clear the trash first."

The panther pounced, claws shimmering with spirit light—Tian Lei flicked his wrist.

Black lightning sliced the creature clean in half. Its body hit the ground before it even realized it died.

"Hmm, black lighting spells are good" Tian lei nodded seeing the power of the spells.

The ape roared, slamming its fists into the earth, sending shockwaves that tore through the clearing.

Tian Lei stepped forward once.

Just one step.

The ape's head exploded from the pressure alone.

The rhino charged, spirit armor gleaming—

Tian Lei raised a single finger and tapped its forehead.

Boom.

The beast's skull caved in like wet clay.

Three kills. Five breaths.

"Not bad warm-up," he said, waving smoke off his hand.

He flicked his fingers and storage seals flashed open. The corpses vanished, neatly stored away like ingredients for a later cooking project—because he needed them fresh to test the bloodline transfer process.

"Alright," he said, brushing off imaginary dust. "Next batch."

He shot forward again, lightning twisting behind him like a long black comet tail.

This time a mid-Spirit Rank Mountain-Bone Lizard rose from the earth, its maw glowing with fire.

It spat a massive blast—

Tian Lei caught it with his bare hand.

"Cute."

He squeezed.

The fireball shattered. The lizard froze.

Then Tian Lei slammed his knee into its jaw.

The entire creature flipped into the air, bones cracking, before he finished it with a downward chop that split its spine.

He stored that corpse too.

A forest tremor caught his attention—three more Spirit Rank beasts clashing nearby. He didn't wait.

"Good. More stock."

Black thunder flashed. In the next ten seconds:

—A Thornhide Boar fell with its heart crushed.

—A Spirit-Rank Vulture plummeted headless.

—A Stoneback Bear died with its spine shattered.

All stored. All clean. All efficient.

Tian Lei wiped a fleck of blood from his cheek.

"That's eight," he muttered. "But I need more high-quality samples."

He turned his head toward a deeper, darker forest where a dense concentration of power pulsed like a heartbeat.

A peak Spirit Rank monster.

His grin sharpened.

"Perfect. Let's go collect the big one."

Tian Lei stepped into the deeper forest, the air growing heavy with spiritual pressure. Every tree he passed bent slightly, leaves trembling as if bowing in fear.

And then he saw it.

A Titanjaw Serpent—a peak Spirit Rank giant, thicker than an ancient oak and long enough to coil around a mountain. Its scales were deep stone-black, glowing with veins of molten gold. Each breath it exhaled sent ripples through the ground.

The serpent reared its head, eyes burning like two molten suns.

Tian Lei cracked his neck.

"Big one, huh? Good… let's test something."

Black lightning wrapped around his arms, hissing and snapping like chained beasts. He thrust both palms forward.

"Black Thunder—Burst!"

A storm of pitch-dark lightning crashed into the serpent's face, the impact shaking the entire forest. Trees were uprooted. Earth tore open. Birds fled in panic.

But when the smoke cleared…

The Titanjaw Serpent was still there.

Barely a scratch on its scales.

"…Huh," Tian Lei muttered, blinking. "That's annoying."
