Li Changgen, an elderly farmer from Qingping Village, carefully cultivates premium Bingtang Cui watermelons. When he delivers his produce, the manager of Lvyuan Supermarket deliberately makes things difficult for him. His daughter, Li Qingyue, is actually the behind-the-scenes chairwoman of Lvyuan Group. After learning that her father has been humiliated, she quickly uncovers a corruption network in which the purchasing director colludes with merchants to sell substandard, poisonous melons, and cleans out the group's internal parasites. When foreign companies threaten to cut off supplies of agricultural chips to force their demands, Li Qingyue remains calm and fights back with her independently developed Shennong chip, breaking through technological barriers and crushing the foreign monopoly. She upholds strict standards for fresh produce and refuses to sacrifice consumers for profit. By establishing a fund to support farmers and helping agricultural producers across the country, she and her father build a national fresh-food industry that remains true to its founding principles.
