If you want to know what kind of person Qin Shi Huang is, the direct method is to see what kind of people he likes to use. And a person's success and failure, in addition to the people he puts in important positions, is also up to what kind of opponents he meets. Any enterprise cannot be completed by one person. If you want to conquer the world, the first step is to compete for talents. Emperor Ying Zheng uses the unscrupulous Li Si, who helps him realize the dream of the unity of the country. But after his death, Li Si betrays him. Emperor Ying Zheng wants to wipe out the six states, so naturally he has a lot of enemies. Among them, the one who impresses him the most is Crown Princess Dan of Yan. Unfortunately, Dan, who is dusted the eyes by revenge seems to treat worthy men with courtesy, but he is indecisive and full of suspicion. As a result, ""The Emperor and the Assassin"" becomes an eternal tragedy.
