Rebirth in the Countryside, Run Mountains, Raise Chickens, Mine, and Make a Fortune

After graduating from college, I joined a state-owned enterprise and managed to become an office director. My career was going smoothly, but I didn't expect that I lost my life after having a big drink with a client. Unlucky? He was actually reborn twenty years ago. Lucky? He actually traveled through time and inhabited the body of a rural boy. Still single at twenty-five or six, smoking, drinking, gambling, and accomplishing nothing! See how the protagonist counterattacks and turns a mediocre peasant into a wealthy country!
