The mc is doing charity I believe, where he takes small payments for any mission. And ends up running into a woman who's clan is on the verge of destruction. He takes her in and helps her rebuild her clan. Two people that Joined so far was an old man who thinks he's young and a kid who's good at setting up traps.

sorry this doesn't have to do with what you're trying to find. i just wanted to be annoying. if it's manhua (chinese comic) murim is not the right word. murim is 武林 / wulin, just the korean pronunciation/interpretation of the chinese genres jianghu/wuxia/xianxia, etc.

Oh I appreciate the correction, I never knew that, so what I wanted to say was manwha. I will correct that at once.
