Dressed as the Eldest Princess of the Tang Dynasty: I Survive by Treason

Trapped in a ruined temple, Xie Ziqing, who has no identity, is struggling in a Tang Dynasty that is completely different from its history. What? You actually gave me an ID card of the eldest princess? What? You actually forced me to get married? What? Did the Tubo Turks go to war with the Tang Dynasty again? What? The Emperor of the Tang Dynasty had his hair cut off, and the second prince rebelled? Xie Ziqing, who is engaged in military reform and economic construction in the southeast, has a determined look: I want to return to Chang'an! There is no Wu Zetian in this era, but it doesn't matter, there is a name that will be more resounding. I, the eldest princess, want to usurp the throne!
