I'm trying to find this manhwa I read a while back but now I can't remember the name of it. It's about this family, the dad is a knucklehead who's physically strong and he married a girl who died giving birth to two boys. The dad opened an inn to make money to raise the sons. One day, a sage (martial art master) came to the inn and gave them a picture scroll as a fee in exchange for food. One of the sons looked at the scroll and became mesmerized by it and he kept staring at the scroll to the point the dad thought he was crazy. Later on, it turns out that the scroll is a martial art manual and the boy been studying it without knowing. His brother left to join a martial sect or something. Some time skip later to his teenager age and mc became strong.

Hopefully someone knows which manhwa I'm talking about, thanks for reading!
