As Zhao Hai's Army advanced, they sent even more people out to Scout. They could see some Wukong-level Masters everywhere in the forest. They could ensure that the Army would not encounter any ambushes as they advanced.
It was actually useful. As they advanced, they had alerted some experts of the sacred Institute. Those experts were all at the sky dance level, and there were many of them. It was obvious that they wanted to attack the Army, but they were all scared away by the sky dance level experts sent by Zhao Hai.
The Army advanced slowly. Zhao Hai did not send his Scouts too far away. He only needed to ensure everyone's safety. Of course, they left enough guards in the cities behind. This time, Zhao Hai only brought less than 400000 troops.
They didn't advance very quickly. Three days later, they finally reached the line of defense formed by the small cities.
