GUI Sheng and the rest only stayed in the small city for a day before they left. Once they left the small city, GUI Sheng and the rest immediately started to look for new cities in the spirit weapon world and prepared to attack those cities.
Although the members of the evil spirit sect could learn about the situation in the spiritual weapon world from the Dean of the sacred Institute, their understanding of the spiritual weapon world was mostly focused on some major events. They didn't know much about the specific situation in the spiritual weapon world.
Therefore, GUI Sheng and the others could only search for the cities in the spirit weapon world. They didn't know where the cities were, but with the speed of the ghost monarch ship, they found the cities in the spirit weapon world quickly.
