Jiang Xun is reincarnated as a single cell and starts out as a laboratory test subject.

Fortunately, he awakens the talent 【Adaptive Evolution】.

As long as he devours living beings, he can gain limitless stat points and evolve endlessly.

To survive, he plays dumb and acts insane on the surface while secretly accumulating power, all for the sake of escaping the laboratory.

Until one day, he meets a conglomerate heiress who was sold off as defective merchandise by her vicious younger sister.

Though born into wealth and privilege, she was unloved by both parents and ultimately met a tragic end.

"Since the world has abandoned you, I'll accept your body—and your regrets!"

The girl dies with a smile, and at the moment of her final breath, a talent fusion is triggered!

【Red Spider Lily】 + 【Adaptive Evolution】 = 【Abyssal Higanbana】

When she opens her eyes once more, the former heiress stands atop blooming spider lilies, transformed into a cold and merciless Reaper with black-and-white eyes.

Jiang Xun: "My dear little sister, your big sister has returned from the abyss."

【Basic Blade Arts】 → 【Blade Mastery】 → 【Blade Specialization】 → 【Blade Expert】 → 【Blade Grandmaster】 → ...

【Flower Burial】 → 【Blood Bloom】 → 【Scattered Blossoms】 → 【Bone Interment】 → ...

...

Years later, the name of the Black Reaper echoes throughout the vast universe.

The myriad races of the cosmos: "Didn't you promise not to come to our planet?!"

Jiang Xun: "Oh, sorry. I got a little carried away with the killing. But since I'm already here..."

Interstellar Reporter: "What drives you to stop at nothing, no matter the cost?"

Jiang Xun: "The wheat back home is ripe. I want to go see it."
