A man in his forties calling a teenager "Brother," the scene... actually isn't that strange.
To be called "Brother," you don't necessarily need to be older, but you certainly need to have strength.
If you have strength, you are the brother; if not, you are the younger brother, and being older doesn't help; you're just an older younger brother.
So, when Zeng Dabao stood before Sun Yixie, he naturally became the younger brother.
Now, Brother wants you, the younger brother, to give fifty silvers. Will you give them? If you don't, that "lesser brother" lying on the ground will suffer.
Zeng Dabao had no choice; who asked him to have such a brother...
Having been an arrest officer in Linan for so many years, he surely had some savings. This time, it turned out, he put it all in.
