Qingdeng Night Talk

There is a green lamp in the world, I don't know who cast it, and I don't know when it was burned. Its light is never extinguished, illuminating Yin and Yang. Under the green lamp, mortals can see ghosts, monks show their cultivation, demons have no way to hide, and all illusions return to reality. The green lantern guards the human world and maintains the delicate balance between the four realms.
