After death, the body disappears, leaving only the soul. Some souls admit that they are no longer alive and are completely relieved; others refuse to accept their fate and become undead wandering the world.
Since ancient times, there have been "spiritual suppressors" to prevent the souls of the dead from killing people in the world.
It's just that since the Liang Dynasty, incidents of undead harming people have occurred frequently. In order not to cause panic in the world, Zhenling people have grown up among the crowd since childhood and gradually evolved into the current civil organization.
