Protagonist Luo Yan: He was once the main god in charge of the cause and effect of all things. Because he was tired of eternity, he lived in seclusion in the modern city and became the landlord of an apartment. She can see and manipulate all lines of cause and effect, and her strength is unfathomable.
· Tenant Zhou Yu: A seemingly decadent programmer actually possesses a rare talent - he can compile the world's "law of cause and effect" into code, and his projects inadvertently touch the underlying logic of reality.
· Special apartment: The building is inhabited by extraordinary beings such as sleeping vampires, recovering swordsmen, and fallen elf prophets. Their "rent" is stories, knowledge or a forgotten history.
