After an experimental accident, modern agricultural engineer Lin Shuer traveled through time and became the orphan Ashu of ancient Qingshi Village. She was squeezed by her uncle Lin Sangui and his wife and was about to be sold as a child bride. Adhering to the principle of "letting data speak", she calmly analyzed the current situation, broke into the back mountain in order to survive, and accidentally rescued Xiao Jue, who was seriously injured and whose identity was a mystery.
Lin Shuer relied on her knowledge of modern agriculture and medicine to treat Xiao Jue's injuries, and cleverly used homemade herbal ointment to temporarily delay his fate of being sold. She also developed mosquito repellent powder and made her first pot of gold, but this attracted the covetousness of Lin Sangui and the prying eyes of unknown forces. She boldly contracted the saline-alkali land in the east of the village and used scientific methods to transform the land. Xiao Jue guarded her secretly and taught her self-defense. The two gradually formed a bond.
Lin Sangui denounced the two men for the bounty. During the roundup by officers and soldiers, Xiao Jue's true identity - the former crown prince of Dayu - surfaced. In a desperate situation, Lin Shuer used homemade lime powder to create chaos, and joined hands with Xiao Jue to break out of the encirclement and hid in an abandoned mine. The two people recognized that they were deeply bound to each other and became partners for survival. Lin Shuer used wisdom to plan a way out, and Xiao Jue used force to protect them. In the whirlpool of the dynastic power struggle, the two launched a desperate counterattack with the goal of survival.
