In the cultivation world, the hundred-year-old good-for-nothing loli Bao Xiaojuan, 1.4 meters tall, relies on the Water Moon Mirror to livestream mukbang to earn snacks. Spurned by her sect, the sect master even wants to send her to the demon sect. She accidentally reels back the heavily injured and amnesiac Yin Wudao, treating him like a cash cow "Ah Cai". Later, she discovers he is actually the demon lord, as well as "Killing All Hypocritical Immortals in the World" who secretly tips her. From their first meeting and testing each other to falling for one another, Bao Xiaojuan proposes three conditions, which Yin Wudao agrees to. She brings the demon lord back to the sect to slap faces and completes her counterattack. Core highlights include the good-for-nothing livestreaming counterattack, the demon lord's tsundere pampering of his wife, and identity unmasking.
