A huge wall spans the sky and the earth, separating the two worlds. Inside the wall is the peace of the dust world, where people adhere to the understanding of "scientific supremacy" and regard myths and legends as false; outside the wall is the concealed reality, hiding the secrets of the blood race that have not been extinguished for thousands of years, and also hiding the endless hidden dangers left by a disease disaster.
A sudden epidemic swept across the world, breaking the long-standing peace of mankind and allowing the Vampire clan, which had been hidden for thousands of years, to resurface. The special disease medicine developed by the Five Saints of Qingtian saved thousands of lives, but accidentally gave birth to "Blood Contractors" with super powers.
The wait at the abandoned train station, the shock of the cool teacher's superpower, the mysterious invitation from Morning Star College, and the truth behind the giant wall... A group of teenagers such as Lin Fei, Er Pang, and Li Dabai were selected out of ignorance and entered the whirlpool of the real world.
They have awakened bloodline factors flowing in their bodies, but they face a dilemma: Should they grasp the power and become ghost slayers who kill evil spirits and protect order? Or will he be backlashed by his bloodline and become a blood slave controlled by the vampires and lose himself?
The shadow of blood disaster is approaching step by step, the secrets of the blood clan are revealed layer by layer, and the lingering power of the epidemic has never dissipated. When the secret of the giant wall is broken, and when the fate of the blood pacters is awakened, they will finally make their own choice between light and darkness - and this choice will ultimately determine the future of the two worlds.
