A Live Show of Ranking Emperors

Fritz wakes up in a parallel world holding a system that posts video to every dynasty across countless timelines at once. The first thing he uploads is a ranking, the ten greatest emperors in history, and it plays on an enormous screen in the sky over Ying Zheng, Liu Bang, Li Shimin, Zhu Yuanzhang and every other ruler in their own eras. They watch their own placements go up and start arguing about them across centuries. The video keeps spreading, the reactions feed each other, and the emperors begin sending things back to him as tips: porcelain, calligraphy, paintings, and older treasures than that.
