In a year of extreme heat and severe drought, people's livelihoods were ruined. Chu Yuan, a young man who traveled through time, relied on solid modern scientific knowledge and an ordinary broken sea bowl to purify niter and hand-rub cold ice. Facing natural disasters and difficulties, he kept his feet on the ground and used wind tunnels and chemical principles to build a shelter, which not only resolved his own survival crisis, but also used ice-making skills to help ordinary people in desperate situations. Facing tests, Chu Yuan always stuck to his original intention, leading everyone to rely on themselves and rebuild order, illuminating the famine with the light of knowledge, and writing a song of praise of relying on wisdom and solidarity to overcome natural disasters.
