I Married into a Wealthy Family and Am Actually the Only Grandson of the Richest Man in the World.

Three years ago, on the order of his grandfather, he came to Jiangcheng concealing his identity, fulfilled the marriage contract of the previous generation, and married into the Su family. This is the last test before he inherits the family - "the world of mortals tempers the heart". For a thousand days, he must taste the warmth and coldness of the world as an ordinary person and sharpen his mind. Today is day 999. If you endure it for one more day, the dragon will return to the sea.
