Is Chang Weisi the first emperor of eto?

In Three-body, Qin Shihuang is not Chang Weisi. In the three-body game, Wang Miao saw that Qin Shihuang, who controls the human computer, should be an NPC. His role is to show Wang Miao and other players that 184 civilized three-body world has used human computers to calculate the three-body algorithm. In the Dark Forest of three body 2, Qin Shihuang, who appeared in response to the side wall plan, is the new leader of e to, but he must be the leader of the Advent School. Chang Weisi is the founder of the Space Force in Asian military forces and advocates the destruction of ETO, so Qin Shihuang can't be Chang Weisi. In addition, Chang Weisi wrote a letter to warn the future space army to pay attention to Zhang Beihai's ideological problems, but it was not taken seriously. The representative of Qin Shihuang's role is the leader of the organization from reorganizing ETO to killing Luo Ji with gene virus. But it didn't reveal its true identity from beginning to end, and even more unexpectedly, it didn't go straight to the doomsday war. It stands to reason that the role of Qin Shihuang is extremely important. In any case, you should explain your life and death like Evans, but it's a pity that you don't. Appearing out of thin air and disappearing at will, it seems that this role is dispensable and irrelevant.
