As an ordinary doctor in the 21st century, Chang An accidentally traveled to ancient times and became the grandson of the richest man in the local area. He thought he could enjoy the life of the third rich generation, but he didn't expect that his family had a big business and his father gambled the most, eventually destroying the family fortune.
