Jiang Lin, an overworked office worker, is diagnosed with terminal-stage illness and has only six months left to live. Just when he falls into despair, he discovers that a miniature cultivation world inside his mind actually exists! This world faces an impending catastrophe as the demonic path devours the righteous path, and every city conquered by the demons worsens his illness; conversely, when the righteous path flourishes, his body heals itself. To stay alive, Jiang Lin sends his consciousness into this world and transforms into a supreme deity from beyond the heavens to aid righteous cultivators. While turning his career around and humiliating his snobbish relatives, he also supports the faltering righteous sect, the Yunmeng Sect, within his mind and joins forces with the aloof holy maiden Su Qianyue to fight the demonic army. This is a dual battle for life and death spanning dimensions!
