Lou Yao, a young man who has yet to become the number one in the world, accidentally rescues the Hansha Fairy, who has been poisoned, lost her cultivation, and fallen into mental confusion. He washes clothes, makes fires, feeds her, and takes care of her for many days, enduring her cold face every day without a single complaint. Little does he expect that after the fairy recovers her cultivation, instead of showing gratitude, she detains him in a cave for strict supervision. Unable to beat her and unable to escape, Lou Yao argues and banters with the proud fairy every day, single-mindedly wanting to break free, but in the end, he is forcibly taken by her as a disciple under her sect, kicking off a hilarious daily routine of master and disciple in the cave.
