Our world has become a show for entertaining the "gods"

Celestial beings are now in possession of earth, and humans are their slaves. The story will have multiple MCs since it won't be the story/legend of one just one person but the story of the creation of a new era. There will be times when two different MCs will fight each other and even kill cause, like I said, not a single dude's story. NO HAREM, NO R-18 & SHITTY ROMANCE cause I am not good at relationships and I do not intend to fuck with your minds with my useless skills.
