Time-Travel Trader

During a harsh famine in the 1960s, a man is stripped of his land and grain by his older brother. An old watch left by his father grants him a system to travel between his era and 2025. Trading vintage items for modern wealth, he buys food and supplies to save his younger sisters. Using grain to barter, he helps his village secure water, drives off bullies, and even provides advanced technology to the nation. Through family betrayals and dangerous challenges, he ultimately lifts his sisters from poverty and fulfills his promise to his parents by returning to school.
