I Am the Big BOSS Behind the Scenes

I traveled through another world and became the only behind-the-scenes source of this world. There is a prophecy circulating in the world: As long as the final BOSS is defeated, all suffering will disappear, and all living beings will usher in eternal peace, without war, pain and lack. But no one knows that the final BOSS is me. The iron law cannot be tampered with: the ultimate happiness of all living beings must be paid for by my annihilation. I have no intention of killing creatures or dominating the world, I just want to survive. So I hid in the shadows, forged countless monsters from the underworld, laid out endless levels, and sent clones to infiltrate the adventurer team, stirring up suspicion and creating a rout. Everyone rushes for salvation, and their salvation is my death. There is no good or evil in this game, only my instinct to survive.
