Mistakenly Cross Prince Daqian, Learn More About the Xuanwumen Incident

[Travel time + traditional systemless + Machiavellian strategy + multiple female protagonists + cool writing + struggle for hegemony + no bulls + the story is delicate and not brainless] Gu Tiancheng. A social beast who had been single for 25 years unexpectedly became a good-for-nothing prince that everyone wanted to beat because of his mistakes. The fiancée is the number one jewel in Daqian, the goddess in the eyes of countless noble men. Hearing that the emperor wanted to marry him to Gu Tiancheng, he was ready to fight to the death. And his brothers all covet the throne. Although Gu Tiancheng is said to be useless, he is still a prince and a thorn in the side of the other brothers. How did the original person die? Poisoned. The ones who poisoned me were among those good brothers. Good news: He died once and is not afraid of death. Better news: He was a history buff in his previous life, and he knew the changes in the Xuanwu Gate by heart. Relive your life, no longer be a good person, be a hero. Fiancee wants to break off the engagement? Are the brothers going to kill him? Father uses him as a pawn? Hell begins. Okay, let's play like this, right? He played this game of chess. In order to deceive others, he raised chickens above ground and trained eight hundred dead soldiers underground. Although there are only 800, 800 is still 800. The first thing to do is to be stronger. Kill your brother, kill your younger brother, threaten your little mother, ascend the throne, rectify the imperial court, unify the world, and rule the nine states... Wait, why are there still monsters and demons? Why is there still a world of immortality? Why are there still thousands of races fighting for hegemony? Gu Tiancheng smiled. It's so boring to be the emperor in Daqian. If you want to be, then be the lord of all realms.
