I Set up a Street Stall in the Three Kingdoms and Made Cao Cao the Emperor

I'm a street stall owner. Cao Cao always likes to chat with me. One gold is not too expensive to chat with me for a quarter of an hour. Later I discovered that if I wanted to build the street stall business into a national alliance, I had to help Cao Cao unify the world. So, while I was engaged in street stall business, I pushed Cao Cao to the throne. The day before Cao Cao ascended the throne, he suddenly discovered a secret. I, the president of the Street Stall Alliance Company, was actually his long-lost eldest son and Mrs. Ding's only son. What will be my ending? Will I become the crown prince, or will I be secretly killed?
