Without the knowledge of the Alliance Army of the evil spirit sect, Zhao Hai had already completed his preparations for the South China Sea. All he needed to do was to reel in his net. Although Zhao Hai's original plan was to set up a magical formation on all the islands in the South China Sea that could be used, they really did not have the time now. Furthermore, they still had enemies outside, who were eyeing them covetously. They did not have the time to do that. They could only wait until things calmed down.
Although he was on the 33 northern islands and only the main island had a formation, the main island was the largest island in the sea area of the 33 northern islands. Each Island had a large area of influence. It could be said that controlling the main island was equivalent to controlling the entire sea area of the 33 northern islands. Therefore, Zhao Hai was not worried about anything.
