A Family of Five, Loyal to Six Countries

The Gu family has a family rule: don't talk about state affairs during meals, and don't poison the soup. Until that day, my father's secret letter fell into the soup. My mother picked it up and took a look. "Beiyan's paper?" Dad's expression changed: "Do you know him?" Mother took out the dagger from her sleeve: "What a coincidence, the person Daliang asked me to kill is also named Gu." The eldest brother put down his chopsticks silently: "Don't do anything yet, Nanchu asked me to protect him." The younger sister raised her hand: "Three thousand taels from Xishu. I want to live." The four people looked at Gu Shouzhong at the same time. Gu Quan sighed and took out a letter from his arms. "Dong Qi asked me to find out who the four of you are loyal to." The family of five was silent. Suddenly there was a knock on the door. "Are you the Gu family?"
