When the Demon King woke up, he found that he had lost all his cultivation, and the system threatened him to do good deeds by deducting his lifespan. During the first mission to save the squirrel, the scene of him squatting under the tree in his blood-stained mysterious robe is full of absurdity. The key turning point is being besieged by the disciples of the Immortal Sect - the ants that were once exterminated with a snap of their fingers, now have to pretend to be dead and escape by relying on the "Turtle Breath Technique" just rewarded by the system. In the end, the image of him clutching the book of merit and deeds while his face was stained with blood was fixed, foretelling the frustrating life of "doing one good thing every day" in the future.
