Mu Yubai widened his eyes, then slapped his head, and said in annoyance: “You’re right! Look at this brain of mine, randomly telling someone to become my sworn brother. I didn’t mean for it to come out that way either… hey! Yun Che boyo… oh, no, little brother Yun, I was rude earlier. Come to my Mu Family for a visit someday. I’ll definitely let you see my sincerity. I, Mu Yubai, promise you that I am absolutely worthy of becoming your sworn brother!”
