Billionaire's Unforgettable Ex-Wife - Chapter 6: Narrow Road Meeting

Protagonist travels between different anime worlds to right wrongs and uncover his reason for being along the way.

A million years ago, he had traversed the Nine Heavens and Ten Earths, braving countless mysterious Life Prohibition Zones, in search of a way to resurrect that foolish woman, but inadvertently learned one earth-shattering secret after another. Thereafter, he went through nine cycles of reincarnation, strategizing over the world, casting his net across the heavens, with the Myriad Realms as his board! In this life, he had returned from reincarnation, his Qi engulfing mountains and rivers, “It’s time to close the net...”

Maid, older sister, younger sister, and even mother, all of them.

Despite being the ruler of a nation, nobody was willing to marry the vicious man with a bloodlust.
