It's about the Spring and Autumn Period and the Warring States Period. I like that period of history the most because it is the human version of the animal world. Tell you that the weak will eat the strong, and tell you that the fittest will survive. It seems that all of them are upright, caring about the country and the people, benevolent and moral, and care about their country and the world. In fact, few of them are serious. After taking off the veil, seeing the face clearly, I suddenly realized that this is history, haha, how unserious! .
