Guyu traveled through time, but it seemed like he didn't wear it completely. There is no system and no space. At the beginning, the family is destitute and the parents are miserable. The only "good news" is that this is an era when women can also take the imperial examination. In order to provide enough food for the whole family, Gu Yu, who had been rolling in the fields since childhood and was familiar with farm work, resolutely picked up his book basket and plunged into the muddy path to the capital. Living in the capital is not easy. While well-educated students were talking about "the people are more important than the emperor", Guyu was studying the pH of the soil in the suburbs of Beijing. While the suave talents recited "A grain of millet is planted in spring", Guyu was calculating the optimal solutions for yield per mu, water conservancy and grain tax. Everyone laughed at her for being a country bumpkin who only knew how to dig food. Her whole body smelled of earth and she was not worthy of being on the stage. Until the palace examination, when faced with the emperor's question "How to secure the world?", Guyu presented a theory on rejuvenating the country through agriculture, from seed selection, seedling breeding, pest control, warehousing, to the allocation of grain transportation from north to south, every detail of the problem hit the mark. The whole court was in an uproar. The young tutor Xie Zhiwei, who was said to be as cold as the moon and not close to the mortal world, lost his composure in the court for the first time and held her back, his eyes were shining like never before. "This policy... If it can be implemented, can ensure that Dajing will not be hungry for a hundred years." Later, the noble ladies in the capital discovered that the peasant girl they looked down on was not only standing in the Jinluan Hall in official robes, but was also "invited" to the palace by the Taifu every three days... To discuss state affairs. Ladies: It must be our illusion! Guyu: Thank you, sir. Don't just watch the practice. Come, I'll teach you how to plant rice. Xie Zhiwei: ... Give me your hand.
