Una ejecutiva cuida un hombre simple tres años, todos se burlan: es el soberano demoníaco oculto.

Jiang Chen, ruler of the demon realm, had his soul trapped for a hundred years, leaving his earthly body weak and demented. Shen Yunshu cared for him with devotion for three years. When his soul returned to his body, Jiang Chen resolved to repay the favor. He then assumed the identity of the powerful and mysterious Jiang Cen, broke a thousand locks, infiltrated the Guilong Hall single-handedly to retrieve a billion, and completed ten top-level missions one after another. He worked as a guard to protect Shen Yunshu while concealing his true identity, punishing malicious relatives, crushing his enemies, and eliminating all dark forces with his absolute power.
