I’m Lin Ye. When I opened my eyes again, the System told me I had died three hundred times. Seven layers of worlds were devouring one another, countless rule-based mysteries entwined like a web, and the “Lords of the Rules” lurking beneath the city’s ordinary surface were harvesting all of humanity. Before my cognitive contamination reached 100, I had to uncover the truth behind the overlapping seven layers of worlds and solve the final rule in a world where no one was allowed to know the truth: Rule Zero.
