What, He Was Reincarnated and Turned into a Mouse

Lin Wangwang, when he opened his eyes, he was transported to a prehistoric world where the weak and the strong preyed on each other, and he was in the body of a mouse. I thought I was going to die again, but my talent for treasure hunting suddenly awakened in my mind! From then on, while others fought desperately for resources, Lin Wangwang dug and dug in the mountains; while others studied the exercises painstakingly, he kept digging and digging. The cultivation level is soaring all the way.
