Infinite Save-Loading from the Start: I Broke the Gods' Game

[Save-scumming + gods and demons + strategic scheming + multiple heroines + calculating protagonist] Su Mu transmigrates to a terrifying world where gods and demons descend and alien species run rampant. Everyone struggles to survive the apocalypse, but Su Mu discovers that he can reload his save endlessly, just like in a game. From then on, he becomes the only one who knows everything. Facing the lofty gods, Su Mu smiles faintly. “I've killed you ninety-nine times already. This time, let's try something new.” Facing the invincible Demon King, Su Mu yawns. “That's all the final boss can do? I know all your skills better than you do.” The apocalypse that others see is, to him, nothing more than a game where he can try and fail without limit. And he is the only player who can beat it!
