Tide Code: Fun in the City

Young Jiang Yu walked into Chaoqi Technology, but was kicked out. He asked face to face: "You want to demolish my house, have you asked the people on the dock?" He later learned that his father's life was buried under the dock, and there was a smuggling tunnel leading to the top of the city's power - an "underground river" worth three billion. The protagonist does not rely on family background or luck, but relies on a line of code and the intuition of a dock boy to play around in this modern city.
