Infinite Trials Starting as a Storytelling Servant

Shen Mo, the protagonist, is a lowly storytelling slave who stumbles upon a mysterious ancient book that can take him across the Myriad Worlds. Each story in the book is a perilous trial world. In the real world, medicine is considered taboo and the cultivation system is monopolized by the powerful. But in the trial worlds, Shen Mo uses the despised "forbidden medical arts" and his golden finger, which lets him manipulate life force, to seize one opportunity after another and crush every prodigy in his path. He uses storytelling to spread ideas and gather intelligence in the real world, and the trial worlds as stepping stones to seize resources and grow at incredible speed. Starting as a slave anyone could bully, he advances one careful step at a time, eventually overthrowing the rotten old order, exposing the age-old conspiracy behind the ban on medicine, and becoming the supreme Medical Sage who holds life and death in his hands.
