Mission Objective: Destroy Human Civilization

Time-traveler Lin Yi arrives in 2030 with a mission: wipe out humanity before they reach the stars. He expects primitive fossil fuels and basic nuclear tech. Instead, he watches a yellow-haired delinquent zoom past on a flying sword. Something went catastrophically wrong with the timeline—and now Lin Yi must navigate a world where ancient cultivation has merged with modern civilization, all while completing his impossible mission from 27,000 years in the future.
