Blood River Sect was a local player sect that was among the top three sects in Baokang. The reason they had managed to get one of the crystal mines from the various powerful sects was because they had given up on the herbal resources in Shennongjia and surrendered the rights to the rare and valuable metal mines. That was how they managed to get the rights to the second level of a crystal mine that was situated in a remote corner of the area.
It was supposed to be a period of time that will be beneficial for Blood River Sect's development, and it was also supposed to be a great, fortuitous chance that would allow it to rise to the ranks of the large sects in World of Martial Arts.
However, since berthierite was very rare and valuable during the early stages of the game, Blood River Sect did not dare to spend all their resources like that. They only wanted to occupy that valuable resource point and slowly become stronger.
