The top killer Ning Yu was liquidated by the organization and traveled through time to become a cute Lolita girl. She was forced to be bound to the doomsday lolita development system. While feeding the zombies, she taught high school student Shen Yiyue how to chop zombies, and gradually grew from a killing machine to a human heart. The two fled to the survivors' base, but unexpectedly discovered that it was actually the slaughterhouse of the Awakened - the founder was using the T-virus to control everything in the name of the human completion plan. When Ning Yu was killed by the Seven Deadly Sins Zombie King, she returned in parallel time and space with all her memories, and the real target of the mastermind behind the scenes was the key in her body that could unlock the root cause.
