Lu Ren accidentally transmigrates to a cultivation world, only to find himself a super good-for-nothing with a damaged spiritual root.
From the start, his fellow disciples scheme to use him as a sacrifice in a demon lair. But inside the cave, he accidentally awakens a sharp-tongued, chatterbox "lie flat System," which forces his first task on him: "Hurry up, the heroine next door is about to get struck down by the villain!"
He has no desire to do the tasks, yet by scavenging and finding hidden treasures, he masters the art of refining immortal pills and gets dragged into the schemes of powerful figures from various immortal sects.
At the sect tournament, he seems to win first place by sheer luck, but behind the scenes, the mastermind is none other than the System's vicious mouth.
Everyone mocks him as a good-for-nothing who got lucky, but only the heroine, Su Li, believes he has noble intentions.
And just as an elder from a top immortal sect prepares to personally bestow a supreme, secret treasure upon this "chosen one," Lu Ren suddenly pushes through the crowd and points to a young female cultivator in the corner: "Sweetheart, give it to her!"
