So this is what I do remember. It start out as any other cultivation manga out there; he gets accepted into a sect and finds a big sword that he wants to use. One of the people who takes notice of him is an elder, I believe, and that elder begins to help him; this elder also has a brother.
I think about 50 or 60 chapters in, the sect gets destroyed by the leaders of 4 very powerful sects, and the two brothers that are elders, and I believe are also twins, take him to an underground place that is a secret in the sect, and lead him away while they stay and fight.
Since the entire sect was destroyed, he became the sect leader and vows to rebuild that sect. I know this is super vague sorry about not having more information.
