Warring States: “The strongest creature in the sea, land and air is Kaido? No, it’s Lu En!”

To save a doomed fantasy world, I killed the main characters, then destroyed the game world, and fell into another timeline as the academy's top seat and rival to the protagonist.Now, I'm trying to save the world and steer it towards a better ending…But I'm the final boss.
