As for the spiritual weapon world, Zhao Hai was more worried because the difference in strength between the spiritual weapon world and the evil spirit sect was too great. The evil spirit sect was a sect of the higher realm, and the spiritual weapon world was one of the many lower realms that the evil spirit sect managed. It would not be easy for them to go against the evil spirit sect.
Furthermore, once he heard the name "evil spirit sect," he knew that they were not to be trifled with. They were not some righteous sect. The righteous sects might not do something like exterminating them, but the evil spirit sect might. Their cultivation techniques and spells all carried a dense ghostly Qi. If the spirit weapon world was not strong enough, the spirit weapon world would probably be destroyed.
