What Should I Do If I Dress up as Yao Chang but I Don't Recognize Him?

With a "Zila" sound, Lin Yan woke up again and turned into Yao Chang, the future founding emperor of the Later Qin Dynasty (although he did not know that his original body was so awesome in history). Lin Yan, who knew only a little about this period of history, originally planned to lead his men to fish for self-protection, but was eventually pushed onto the road to hegemony by the suspicion of the Fu clan. Many years later, someone asked: "How did your Majesty resolve Fu's death?" Lin Yan put down the sketch of the improved equipment in his hand and smiled lightly, "It's very simple. I will become the emperor."
