In the ten years since the end of the world, Sun Lei has witnessed the darkness of human nature, but at the last moment he was pushed into a zombie swarm by his teammates. When he opened his eyes again, he actually returned to eight years ago - a peaceful world where the end of the world had not yet come. This time, he no longer pursued apocalyptic survival skills, but used his future knowledge reserves to open a farmhouse in the countryside. Grow vegetables, raise fish, cook delicious food, use modern management concepts to operate traditional industries, and use food safety knowledge to create a reliable brand. While the former betrayers were still struggling in their conspiracies to prepare for the end of the world, Sun Lei had quietly built his own business empire. However, the chain reaction caused by the butterfly effect caused the predicted future to deviate from the track. A new crisis is brewing. This time, can he protect this hard-won pure land?
