The shoreline of Luhui Island is disappearing every day, and satellite forecasts predict that the center of the island will be engulfed by the tide in the next 20 days. Chen Lizhou, a 33-year-old unemployed structural engineer, did not wait for the rescue ship. Instead, he led the islanders to remove waste fishing rafts, plastic barrels, old pontoons and resort building skeletons to build floating modules that can rise and fall with the tide and can be detached and connected. Fisherman Lin Apeng did not believe in the drawings, doctor Su Qin insisted that the sick and weak should be given priority, and travel company leader Zhou Haikuo used ship slots, supplies and credit to fight for the initiative to evacuate. What's even more fatal is that in order to prove that he had concealed the connection cracks, Chen Lizhou almost capsized the platform. The island is getting smaller and smaller, and the floating city is getting bigger and bigger; but after tens of thousands of people are actually transferred from the deserted island, fresh water, garbage, private buildings, aging materials, property rights and control rights begin to turn an escape into a long reconstruction.
