Who would have known that the entire South City wholesale street where his son's restaurant is located actually all belongs to him! Lu Changgeng originally wanted to hand over the family business to his son, but was met with utter contempt on the opening day. As major bosses appeared one after another and a four-hundred-million acquisition knocked on the door, everyone was shocked to discover that this inconspicuous old vegetable seller is actually the true Lord of South City!
