"Senior brother..."
One of Lu Mingfei's hobbies is to call his family's (!) Dear (!!) Zhuma - the president of the Lion Heart Society named Chu Zihang - senior brother. He likes to see that paralyzed face that seems to have the same expression for thousands of years, just because of his own two words - even though it is just a slight frown invisible to others, Lu Mingfei is already very satisfied.
Yes, he has a bad taste. How about you come and bite him? But before the plan is implemented, you will be cut in two by Murasame - oh, maybe Muramasa or another knife.
