Shen Jinghe, a top student majoring in modern agriculture and biotechnology, once transformed into a cannon-fodder heroine of the same name in a novel from the 1970s, who died unexpectedly due to her infatuation with the male protagonist, an educated youth, and her family fortune was swallowed up by her best relatives. Awakening by the cold water, Shen Jinghe clenched her fists in the face of the dilapidated eaves, the eyeing aunt, and the weird "harvest harvest" system in her mind that urged her to "collect the first native rice seeds": Love brain? Whoever likes it should be treated as such! Her goal is the stars and the sea... Ah no, it is thousands of acres of fertile land and space filled with supplies! Use foresight and technology to improve grain varieties, establish cooperatives, and secretly stockpile supplies. The rewards of system tasks are generous, but they are also shocking at every step. But, why is that veteran brother who always appears when she is doing her career, with eyes as sharp as an eagle, always hanging around her? She also said that her rice was more fragrant than anything he had ever seen? Let's see how she uses her left hand system and her right hand space. In this turbulent era, she refuses the fate of cannon fodder and embarks on a counterattack path of promoting agriculture through science and technology and full of supplies, and by the way, she gains unexpected love.
