My HRE Empire: from Nicoburg to the Elector

[Western Middle Ages + Slow Heat + No System + Farming + Struggle for Hegemony] The protagonist Lu Ye traveled through the Shinra and woke up to find that he had become Frederick I. Now, on the eve of the Battle of Nicopolis in 1396, 30,000 Crusaders are heading towards the Ottoman ambush circle. The French are still clinking glasses to celebrate, and the German princes are in disarray. Only Lu Ye knew that in a few days, the Danube River would be dyed red. He has a PhD in history. He knew who would die, who would escape, and who would become a laughing stock after this fiasco. He also knew that the young king Sigismund, who was looked down upon by the princes, would become the emperor of the Holy Roman Empire in the future. He pressed the hilt of his sword and made his decision. Use six hundred years of foresight to bet on a way out. From Nicopolis to Brandenburg, from defeated general to imperial elector. Many years later, when the Hohenzollern flag was hunting at the Brandenburg Castle, Frederick recalled that bloody morning on the Danube River, the emperor he had dragged out of the quagmire of history, and the political opponents who choked to death on his words at the elector meeting—— "My Shinra Empire," he whispered, "I fucking built it myself."
