He was born the young master of a wealthy family, the legitimate son of his parents, brilliant and gifted. But after falling into the water at the age of six, he became an imbecile.
When the fool turned eighteen, his family arranged for him to marry Sun Jiaojiao, a country girl. Sun Jiaojiao took her husband, Hu Zilin, to seek medical treatment again and again, and little by little, his intelligence returned. Just as their happy life was beginning, Master Hu and his wife of many years, Madam Qiao, suddenly died together. The family fortune was divided up and squandered, and Hu Zilin and Sun Jiaojiao were turned out with nothing. His illegitimate elder sister shoved Sun Jiaojiao, causing a difficult labor. Hu Zilin frantically carried his wife to seek medical help, but the people who claimed to be their family stopped him again and again. Sun Jiaojiao died along with her baby, and Hu Zilin was beaten to death with clubs.
Filled with hatred, Hu Zilin was reborn at the moment he fell into the water before his wedding. He continued pretending to be a fool, seized the family fortune, and took revenge on those who had wronged him.
