At the Beginning, I Killed the Son of God, and I Snatched the Destiny and Became a Saint.

Qin Zhan traveled through time and became cannon fodder for a small family that was about to be exterminated in a fantasy world. When he was desperate, he discovered that the world was overrun with "protagonists"! There are loser-style protagonists who wear grandpa rings, there are rebirth-style protagonists who hold scripts, and there are Goudao-style protagonists who are bound to the sign-in system... And Qin Zhan himself is just the background board in these "protagonist" stories, which can't survive more than three chapters.
