Luo Xiao did not doubt wether the two brothers had any good martial art techniques. The weaker factions only had average scriptures, and only a few would be categorized as good. These factions were very well aware of their ability to fight against the more powerful sects and clans, so they were struggling in their own way.
However, they were not able to give these techniques to their disciples without anything in return. As the weaker sects, they gained many disciples from ordinary families. Their disciples were not rich, and they could not provide their own resources when cultivating. Everything they needed had to be gained from the sect.
The sect, in return, needed to earn enough resources for their disciples and their staff, so they would make various tasks and events that could provide these talents with contribution points to change for skills or resources in return.
