Jiang Xiaohai's senior year in high school started with a physical spin - he was knocked three meters away by the mysterious transfer student Su Li, dragged into the men's bathroom stall, and stuffed with a strawberry headband. He instantly became the school's gossip headline. What's even more frightening is that his childhood sweetheart Lin Mengmeng's "biochemical weapon-level" love lunch box, the rooftop death threat from the electromagnetic delinquent girl, and the thousand-year-old hungry ghost's roar coming from the bronze tripod in the school history museum are pushing him into a superposition of social death and real death.
When the ancestral bronze key resonates with Su Li's Taotie Pendant, Jiang Xiaohai is forced to inherit the power of the beast that devours all things. Now he not only has to deal with the crisis of the Antiquities Research Society and avoid the "quantum mechanics" interrogation of the dean, but also has to survive hard between the rampaging superpowers and the rampaging beautiful girls - such as getting Lin Mengmeng's star-gazing faction to stop spraying rainbow fish bones, or stopping Su Li from eating the entire cooking club in the cafeteria.
However, as the twelve zodiac artifacts gradually awakened, Jiang Xiaohai discovered that his grandfather's "Relics of Mountains and Seas" actually recorded prophecies of annihilation, and the beast patterns appearing on the necks of the girls around him were drawing him into a gluttonous feast that spanned a thousand years. When the countdown to the death of the electromagnetic girl reaches zero, what sounds in the rain of cherry blossoms on the rooftop, is it a heartbeat or a death knell?
