The nuclear explosion laboratory collapsed, and when I opened my eyes again and sat in the wild, there was only a box of chloroquine next to me. In the deep mountains and old forests, I was chased by a tiger as big as a small mountain. It wrestled and rolled to the feet of a bald man who looked like an iron tower. The tiger didn't dare to roar at him. He looked down at me and asked: "Who are you?" I said my name was Liu Xian, a medicine dealer. He said his name was Dian Wei and he was hunting in the mountains. In this world, I have to survive first.
