Zhang Mao has a younger brother who is lively and cute and fights every day.
Later, the younger brother grew up and joined the army, while the elder brother ran a business at home. Later, he became a rich man just to be his younger brother's backer. Every day I worry that my younger brother is a novice, and there is no shortage of BMWs, armors, and weapons.
Then one day, my brother came back and brought a large group of people with him.
Zhang Mao: I always thought you were a rookie, but in fact you are a boss, but a boss is still a younger brother, the one I protect. : D
The protagonist is capable of both literary and military skills, and is better at fighting than his younger brother. (My younger brother is a historical figure and quite famous.)
Purpose: Cutting off one's own legs
