During a famine in ancient times, the porcelain maker Li Shouzhuo accidentally fell into the modern world while chasing a wild hare, and met the scavenger Biao Zi. He brought modern bread and beer bottles back to ancient times to save his family, but was targeted by a corrupt county magistrate who step by step pressured him for glassware, even threatening his family's lives. Old Man Li raided the execution ground and killed the corrupt official. The eldest princess A Yao, traveling in disguise, strongly protected Old Man Li and set a one-year agreement. The prime minister set up a trap to blockade Li Family Village. Old Man Li brought modern seeds, agricultural machinery, and drones, enabling the whole village to have a bumper harvest during the famine and repel the barbarian tribes. In the end, the emperor conferred upon him the title of Imperial Tutor, Li Tiexin married the eldest princess, and Old Man Li's family was reunited.
