My Son-In-Law Is a Little Crazy

Fu Qing, a well-known old Chinese medicine doctor, unexpectedly became the third son of the wealthy Fu family. The original owner pursued Li Wenwen, the daughter of the Li family, the richest man in Jiangcheng, but failed for many years. However, when the Li family needed a happy marriage, he agreed to marry into the Li family. What's even more speechless is that he was also bound to a demon-making system and was forced to embark on a path of becoming a demon.
