In his past life due to a sandstorm, Chen Yuan had three hundred tons of Hami melons rot in the fields, incurred three million in debt, and stood on the rooftop for three hours. Opening his eyes again, he has returned to 72 hours before the sandstorm, opening the photo in his phone's album of himself standing in the rotting melon field, his gaze changing from confusion to coldness. He mortgages his house, wagers all his family wealth, and returns to the village with twelve refrigerated trucks to buy melons. Everyone is mocking him, eight yuan a pound, are you crazy? Only the poorest Tuotuoya village signed the contract in full. Three days later, the sandstorm arrives as promised. Those who rejected him see their melons rot on the road; those who signed the contract do not lose a single melon. Chen Yuan says, it is not that the contract is good, it is that you take the contract seriously.
