The protagonist, Chen Fan, is a plastic surgeon who transmigrates to the Hundred Flowers Sect, a demonic sect teeming with beautiful women. He's an undercover agent sent by the righteous sects, and due to the low status of men in the sect, he desperately wants to escape. However, he catches the eye of Hua Feixue and learns that all his fellow undercover agents have died. To survive, he uses his massage and beauty skills to win the favor of the beauties; anyone who experiences his treatments gains a significant increase in cultivation, making him highly sought after. Chen Fan helps the Hundred Flowers Sect cultivate female cultivators and has its disciples do live-streaming sales, earning the sect a year's worth of spirit stones in just a few days. This transforms the Hundred Flowers Sect from a hated sect in the immortal realm into a highly sought-after celebrity, attracting collaborations from the four major sects. Finally, the protagonist realizes that the Hundred Flowers Sect has never harmed anyone; on the contrary, it was the righteous sects who stole their secrets, making survival impossible. In the end, he eliminates evil and promotes good.
