Although they didn't invest a lot of troops and the undead army didn't have complete control of the hidden fog world, Zhao Hai wasn't worried at all. The yunlai Kingdom wasn't a threat to him.
What made Zhao Hai happy was that the areas in the hidden fog world that were conquered by the undead creatures could already provide him with a lot of power of faith. This made Zhao Hai overjoyed.
Putting aside the matter in the hidden fog world, Zhao Hai turned his attention to sunny city. Two days ago, Zhao Hai had sent his liquid silver Association to sunny city to understand the basic situation there.
The reason why Zhao Hai was able to enter sunny city so quickly was all thanks to tie zhantian. Two days ago, tie zhantian had sent some people to sunny city to make preparations. He was waiting for Zhao Hai and Zhang Feng to go to sunny city two days later to select their people.
