KO One: From the Start, Born in Black Dragon's Lair

Su Nan was an unlucky guy who got run over by a truck even while hiding out at his rural home. He was reincarnated in the Golden Dimension of the Ultimate universe.

From the start, he was born in the lair of the big boss Black Dragon. His exceptional supernatural talent caught Black Dragon's eye, putting his parents in danger.

Fortunately, he received a compensation package from the Myriad Heavens Transmigrator Alliance, which yielded five astonishing rewards and let him launch a dimensional assault right away.

A physique that grows stronger the more you fight? A million-point combat power? The reincarnation of the Flame Messenger? In the face of the Eternal Holy Body, none of them are worth mentioning.

The Martial Arts Judgment Office, the Iron Dimension Alliance, the Temple, the Kingdom Organization: before the Eternal Holy Palace, they are all mere ants.

While Black Dragon was still dreaming of mastering his demonic arts and ruling the Golden Dimension, Su Nan had already left the chessboard and was watching Black Dragon's performance from the sidelines.

When Diabolo the Demon Lord led his demonic army in a fierce attack, aiming to overthrow the Iron Dimension, Su Nan had already brought the four dimensions under his control.

While the divine envoys rushed around to maintain the order of the dimensions, Su Nan became the Lord of the World and eradicated the source of trouble once and for all.

Before he knew it, he had reached the pinnacle of the world, holding the fate of every living being in one realm in his hands. The problem was, he had never intended to become its ruler.

P.S. An invincible slice-of-life story with multiple heroines and plenty of original worldbuilding. This novel and its characters are entirely fictional. Any resemblance is purely coincidental.
