Yan Zhan was the name of the head of the Yan Family, the famous General Yan.
In the account of Old Master Yu, it was Yan Huaizheng who had eloped with his daughter, leading to a full-scale search by both Yu and Yan families.
Yet, during their elopement, Yan Huaizheng shamelessly impregnated Shuzhi.
After the couple was found, Old Master Yu, in a moment of anger, accidentally injured Huaizheng, putting his life in jeopardy.
When Yan Zhan heard the news, he arrived to see his dying youngest son and in a fit of rage, started a fight with Old Master Yu.
Previously, before the Yu Family ventured into commerce, they were involved in illegal activities, and Old Master Yu and Yan Zhan had formed enmities during their youth.
When new grievances were added to old, neither man held back. Old Master Yu was unguarded and Yan Zhan pushed him, causing his right eye to hit a sharp object and become disabled on the spot.
