Gao Ruolan, a lying flat woman, crossed over to the peasant girl Gao Wutong and found that this was a projection of time and space in the Bohai Kingdom at the end of the Tang Dynasty in history. In order to survive, she left her original family and came to her uncle's house, improved recipes, researched condiments, planted shiitake mushrooms, stocked silkworms, and led her family to get rich. In the process of starting a business, Gao Wutong unexpectedly found out that his identity was the princess left behind by the Dongdai royal family, bearing the royal blood of the Dongdai Kingdom and the Xingluo Kingdom. Gao Wutong was reluctant to make a noise, and adhered to the principle of "digging deep holes, accumulating grain, and slowly becoming king", and secretly developed his own strength. Her success attracted the prying eyes of others, kidnapped her two younger brothers, and tried to seize the technology and industry in her hands, but was thwarted by her childhood sweetheart partner Lin Feng. When the old people reunited, Gao Wutong was surprised to find that Lin Feng was from the same world as himself, but his current identity was a mountain bandit. After some discussion, the two decided to start a business together, cooperate to conquer the alien countries of Xingluo and Wa, and give Huaxia a safe environment to repay the harm caused by these two countries to their own people in their previous lives. The two men formed an army to find new seeds to improve agriculture, mine mines, and develop industry, and soon became the strongest force in the vicinity. After completing their own strength accumulation, the two of them refused to be appeased by the Dongdai Kingdom, and began to swallow the Xingluo Kingdom, crusade against the Wa Kingdom, vigorously implement the immigration policy, and gradually integrate the Xingluo people and the Wa people into the Huaxia people. The island chain surrounding Huaxia has also become a barrier rather than a shackle for Huaxia. In the long-term cooperation, the relationship between the two people has also improved by leaps and bounds, and finally they have become life partners. Gao Wutong lived the lying life she expected again.
