Yang Yu was reborn, returning to his high school days, to an era before the Fourth Desolate God had descended.
Armed with the world's strongest authority, he subdued a girl who called herself the System. He had hoped to reclaim the beautiful memories of his past and write a youth that could finally be cherished properly, but this youth... seemed a little too dazzling, didn't it?
A pure-hearted landlady, a cool upperclasswoman, a sweet and silly heiress... an elven saint, a spirit princess, the Dragon King's daughter, the ultimate divine weapon…
And how did even the System end up...?
This is the story of a boy who, carrying the memories of the mightiest and the power of the Void, is reborn and embarks on a path to slay the gods, overturn the world, and destroy fate.
