I Asked You to Marry Your Sister-In-Law, How Did You Become a Powerful Official?

Yang Xuanyu woke up and became the second son of General Pingyuan of the Great Hong Dynasty. My father was seriously ill and could not wear armor. My brother went to war in his father's stead on their wedding night. He died in battle within a month and the border fell. In order to avenge the country and the family, the sister-in-law, who is a princess, came to Yang Xuanyu and said that she wanted to marry him. Yang Xuanyu was confused: My eldest brother just died and his body is still cold. Do you want me to marry my sister-in-law? Sister-in-law: The hatred for killing your husband is irreconcilable. It wasn't until his sister-in-law came to visit late at night that Yang Xuanyu understood that his sister-in-law wanted to help his eldest brother get revenge. However, although she was a princess, she was not qualified to lead troops in the Great Hong Dynasty. In order to have soldiers and horses to avenge her elder brother, she could only remarry quickly and lead the army in the name of her new husband. And he, Yang Xuanyu, is the best cover. Faced with his sister-in-law's request, Yang Xuanyu agreed. Ten years later, Yang Xuanyu embraced the princess: Today, millions of soldiers and horses are engaged, and the world is a gift, to organize a unique wedding for you!
