(This book is also called "Urban Black Dragon King") Jiang Cheng's wish in this life is very simple, that is, to have a beautiful wife, and then raise a dog, so that the two of them can live a low-key life without shame. However, life always backfires... He went out to save money, and the presidents of the five major banks came to receive him in person, served him tea and water, and presented him with a black card! He had nothing to do with a few gangsters, and bigwigs from Hongmen, Black Belt and other parties immediately gave him generous gifts and expressed their apologies. Occasionally, when I travel abroad, I will meet the Rothschild family, a top financial family, who come to pick me up at the airport. At that moment, Jiang Cheng's friends felt sad looking at these big guys who often disturbed his peaceful life... As expected, being low-key is the best way to show off!
