The blood kill sect accepted missions to kill low-level disciples of other sects in order to train the disciples of both sects. This was something that all the sects knew. Therefore, although the blood kill sect was an assassin sect, it was still accepted by the other sects. Furthermore, they had a good relationship with the giant demon sect. Of course, it was normal for them to have a bad relationship with the dark ghost sect. After all, who didn't have two enemies?
However, the Rahu sect was completely different. The Rahu sect was extremely mysterious. Although everyone knew that the Rahu sect was located there, that Sea area was a forbidden zone. Anyone who entered that Sea area without the permission of the Rahu sect would be attacked by the Rahu sect. They would either die in that Sea area or leave it.
