Caged by the Sky, I Kill the Gods with My Mortal Body

They say that the sky is an eternal barrier that protects the world, and I am just an ant surviving under the barrier. When the barrier cracked and the disaster came, they pushed me onto the chessboard as a chess piece that could be sacrificed at any time. They watched me get involved in the murder case, watched me being hunted, watched me step by step towards the altar they set up, thinking they had everything under control. But they didn't expect that as a sacrifice, I would in turn devour the gods and wield the sky-cutting sword. Now, their gods are on the run and their worldview is shattered. Do they want to sacrifice everything for a chance of survival? It's late. I will smash this cage to pieces and let them see with their own eyes what the sky outside the sky looks like.
