Title: Class-A Sequence: The Hybrid Synopsis: In a futuristic world where humanity coexists with "Extraordinary Beings" like Vampires and Werewolves, Chen Zhe is just an ordinary orphan high school student trying to survive. His life is shattered when he becomes the prey of an A-Class Vampire, "Gluttony" (Sequence 02037). Injected with a lethal toxin that turns victims into mindless "Walkers" within 24 hours, Chen Zhe is given a death sentence. Desperate and unable to afford the exorbitant cost of divine healing, he gambles his life savings on a black-market "blind box" serum—a game of Russian roulette where failure means death or zombification. He wins against the odds, but with a twist: the serum he injected was from a Werewolf, the vampire's natural enemy. Instead of dying, Chen Zhe undergoes a unique mutation. He possesses the pale skin, slow heartbeat, and bloodthirst of a Vampire, yet wields the beast transformation and explosive power of a Werewolf. Now a biological anomaly bridging two warring species, Chen Zhe must hide his identity from the government’s "Special Group," the Vampire clans, and the Wolf King’s tribe. As he navigates high school politics, monster outbreaks, and shadowy organizations, he discovers that his existence might just be the key to a new evolutionary sequence.
