Datang: Take Li Shimin on the Bus at the Beginning

If I say that I have a friend who is the author, I just checked a fake Qiandu and thought that Empress Changsun died two years before Li Shimin died. I don't know if you believe it or not... More importantly, the fake Qiandu also said that Li Shimin's death was caused by missing Empress Changsun... Then the author decided on this setting... I think one of my friends is right. Just think of it as a parallel dimension. If I get angry and break your body, my friend said he can't afford to compensate...
