After Xu Yi, a top student in northern Qing Dynasty, was humiliated by his boss, he awakened to the "strongest agricultural assistance system" and resolutely returned to his hometown to help farmers. He relied on systematic black technology to build a super ecological farm, grow sky-high-priced fruits and vegetables, and lead impoverished villages to counterattack and generate hundreds of millions in income. Faced with internal and external troubles, Xu Yi used his wisdom and strength to overcome all obstacles, and finally gained national recognition, turning Qinghe Village into a legend of rural revitalization.
