Kou Yu died in the earthquake and was reborn in a world growing out of darkness. Here, lower-class people can be injected with dog genes because they can be more obedient and loyal, while upper-class people are willing to be injected with wolf genes because they can be stronger. This kind of rule is doomed to plunge society into darkness, tilt the balance to one side, and make life and death a matter of indifference.
Kou Yu had long been disappointed with the world and despaired of human nature. He was wandering in the darkness, but someone stretched out his hand and was willing to hold him out and bring him a little bit of light.
Intention: Just to express some unhappiness and hope that people watching will be happy in the end
