I have read all the first three books, and I feel that most of the characters are well described, but many characters have directly perfected him, such as Shang Yang and Qin Xiaogong, whose descriptions are quite different from the real history. Although it was written according to the background at that time, it felt like unofficial history's collection. For example, the king of Qin can lift an elephant, but in the end he can't lift the tripod and it is directly smashed by the tripod, and so on. Moreover, Qin is super powerful. In the war, Qin often suffered hundreds of casualties, and other countries suffered tens of thousands of casualties. Basically, the casualty ratio of Qin State and other six countries is 1 several hundred (Tian Lei led the team is 1 several tens of thousands), but at present, it is really the best book to write the history of Qin State.
