Xiami runs a scratch-off lottery shop that connects to ancient times, where miraculous medicines, extraordinary treasures, and historical secrets can all be revealed. Zhu Yuanzhang arrives with Empress Ma to save their imperial grandson, but unexpectedly scratches off the secret of the Tumu Crisis. He then uses a summoning card to bring the white-haired Zhu Di right before him, and the father and son immediately begin settling old scores. As Qin Shi Huang, Li Shimin, and Zhao Kuangyin visit the shop one after another, hidden dangers threatening their dynasties and the absurd antics of their descendants are gradually exposed. The emperors go from pounding the table in disbelief to eagerly reaching for their money. After the scratch-off lottery is upgraded, the emperors even join forces to travel through time to Coal Hill and prevent Chongzhen from hanging himself. When founding emperors witness the final days of their dynasties with their own eyes, can they rewrite the fate of future generations?
