Hao Shuo, a product manager at a major internet company, dies suddenly after working overtime for 72 consecutive hours. Because he slept exceptionally well while alive, the underworld recruits him directly as a full-fledged spirit officer. In this world, ghosts are often tormented by insomnia because of their lingering obsessions, until their spiritual energy runs dry. Hao Shuo, however, has a limitless supply of spiritual energy because he “can sleep, and sleeps well.” More importantly, he brings the wisdom and empathy of a big-tech product manager to the underworld, rising rapidly thanks to his outstanding professional skills.
When a grandfather can't let go because he's worried his granddaughter won't manage on her own, Hao Shuo soothes his restless soul with a peaceful night's sleep. When he encounters a fellow worker who can't put his job behind him, Hao Shuo helps him finish his weekly report. When a 12-person team dies unexpectedly during a company retreat, he guides them to let go of their obsession with launching their product and drift peacefully to sleep. He also helps a girl who died far from home find her boyfriend, before finally returning to her mother. With his excellent sleep and his “product mindset” for resolving obsessions, he works in turn for the underworld's departments of soul-reaping, judgment, reincarnation, and more. Thanks to his exceptional abilities and compassion, Hao Shuo rises from a low-ranking spirit officer until he is ultimately chosen as the Great Emperor of Fengdu. Using the simple remedy of “a good night's sleep,” he heals countless wounds in the underworld and brings a long-missed sense of peace and warmth to the realm of the dead under his management.
