I'm a new author, so please go easy on me.

Orphaned, timid, and spineless, he was pushed around by the neighbors in the courtyard compound. They even stole his younger sister's food, and in the end, he froze and starved to death. After transmigrating into his body, Lin Yan brings a soldier's iron will, composure, and combat skills. He has a clear goal: stay in the courtyard compound, protect his four younger sisters, build a prosperous life, and make every scoundrel who bullies them pay.
