Modern poverty alleviation cadre Chen Fan went to the remote fishing village of Pingshawan for village-based work, and accidentally time-traveled to the old days on the way. Seeing that this place was barren and backward, he single-mindedly led the villagers to shake off poverty and become rich, promoting new systems, opening factories, and opening up trade channels, step by step giving the poor fishing village a complete makeover. During this period, he fought against evil gentry and resolved crises, winning the trust of the entire village. When three years of hard work were about to reap results, Chen Fan suddenly realized that this mudflat he had treated as an impoverished village was actually the future renowned Lancheng. Faced with the opportunity to return to his original world, he looked back at the loved ones and fellow villagers who had stood shoulder to shoulder with him, and finally chose to stay, personally participating in and witnessing the rise of a legendary metropolis.
