According to legend, there is a kind of insect called spirit binding in the world.
Male and female souls are born from the same egg and share the same consciousness. After binding the identical egg spirits and placing them into the bodies of living people and puppets respectively, the human souls will slowly pass from the male worm to the female worm's possession through a certain circle of heaven, and become one with the female worm. It's called the spirit-bound body.
There is still a breath of the body, but it has lost consciousness and is like a vegetative state.
Although the spirit-bound body possesses ontological consciousness, its body is controlled by the worm.
As long as the body is not dead. Then he will live forever only at the mercy of others. Life is worse than death, and death is nowhere to be found.
