Red Alert War: No Mine? Aren't the Devils Mines?

Introduction: There are red alerts when traveling through time, but as an ordinary person, where can you find gold mining? Yu Feiyang was dumbfounded: Just keep lying down... Until he arrived at the battlefield, the system suddenly popped up a prompt: [Gold mine detected, do you want to mine it? Yu Feiyang, who was lying on his back, stood up in an instant. He looked at the corpses of the Japanese everywhere and stretched out his hands: "Hey... Hey... Hey..." A private corpse costs 200 gold, and a major general's head is quoted directly by the system at 1 million gold! Damn it, these are all walking mountains of gold!
