Two Realms: Building an Empire from the Farm

Li Qinghe inherited a farm in Ukraine. He thought he would be a farmer all his life, until he found the door in the barn. Behind the door is a low-temperature wasteland world six hundred years in the future, where radiation is everywhere, alien beasts are rampant, and human life is thinner than paper. But there is as much gold as there is stone, and arsenals are everywhere. The wasteland warlord laughed at him for being stupid, exchanging food for gold? Li Qinghe was also laughing - the warehouse was filled with gold, and the weapons were enough to arm an army. Traveling between the two worlds, his farm looks the same every day. Steel walls were erected, drones were flying in the sky, and ammunition depots were hidden underground. Are the neighbors jealous? Mercenaries coming to rob? Li Qinghe took out an electromagnetic rifle, and behind him was an armed legion that he had built himself. One day when the two countries went to war, a cannonball fell into the farm. He summoned the ambassadors of the two countries and drew a circle around the farm on the map: "Anyone who attacks our farm will be punished no matter how far away!"
