My Toilet Connects to the Past, and I Became the Ancestor

If you could switch identities with your ancestors, what would you do in their place? Mu Qing accidentally opens a Door that connects the past and present, meets one historical figure after another, and switches identities with them to help fulfill their wishes. The anguish of bombardment, the resolve of the Ming Dynasty, the sorrow of the Song Dynasty, the might of the Tang Dynasty, the iron will of the Qin Dynasty, ancient civilizations... One world after another changes because of Mu Qing, and he receives gifts in return from his ancestors. The Imperial Jade Seal, the Nine Provinces Cauldron, the Xuanyuan Divine Sword, the Twelve Golden Men, and the Fuxi Zither, which looks more like a weapon than a musical instrument... One day, Mu Qing opens the Door again and freezes in place. Standing before him is a half-mechanical man named Fuxi.
