The two worlds of humans and monsters are like two countries, with borders, diplomacy, and laws. Demons feed on human emotions, all seven emotions can be eaten, and extremely strong emotions are a great tonic. Humans need the power of demons to suppress disasters, drive away evil spirits, stabilize earth veins, and regulate wind and rain. The balance point is not to be too close (if the demon becomes emotional, the order will collapse), nor too far (if the demon becomes emotional, the demon will starve to death). They need each other and hate each other; they depend on each other and fear each other. This is a rule set by heaven and earth, and no one can unravel it.
Intention: This story is about - the empty person catches the person who dare not love, and takes the path that others cannot take, so that those who come after him no longer need to be afraid. This way is feasible. Only one person is needed, and the heart is like an empty bowl.
