I Become a Sage by Roasting People

After Meng Xuanze is betrayed by his girlfriend and his mother falls gravely ill, he tries to stage an accident with a rich heir's car, only to be sent flying by a female CEO. On the brink of death, he awakens the power of an ancestral jade pendant and joins the “Myriad Realms Ancient Immortal Healers chat group.” Emperor Qin Shi Huang sends red envelopes, Jing Ke seeks comfort, Xiang Yu and Liu Bang trade insults, and a sharp-tongued girl floods the chat with messages. Meng Xuanze thinks they're all delusional role-players, until he claims a red envelope: a Marrow-Cleansing Pill that transforms him overnight. From then on, he collects negative emotion points to exchange for ancient medical knowledge and cultivation techniques. In an age of global martial arts, with subterranean realms invading and wars raging across the Three Realms, Meng Xuanze gets stronger by roasting people, using silver needles to decide life and death and flying swords to slay emperors. In the end, he unifies the Three Realms, marries twenty-two wives, and establishes a new order. The group chat is still lively: Emperor Qin Shi Huang is still playing Fight the Landlord, and Jing Ke is still driving for Didi.
