A severe rainstorm is coming, and eight million people in the water city are in danger. Sixty kilometers of flood drainage channels must be dug within ten days. No one in the entire engineering community dared to undertake such an urgent task. When Qin Feng took over the task, the engineering community felt that he was cheating; when the 100-ton truck came back, they all felt that Qin Feng was a devil - why are there so many 100-ton trucks? However, Qin Feng shocked the world far more than that. Relying on the "god-level building system", using popularity to exchange equipment, and facing the obstruction of peers, the project was finally completed ahead of schedule and saved the whole city. The project shocked the world at home and abroad, and Qin Feng was invited to undertake international projects and start a new journey.
