The reason why Zhao Hai did not set up the array near the Hidden Cloud Village was because it was too sensitive. Zhao Hai wanted to wait for the people to investigate the situation in the village before setting up the array. He believed that those people would not appear for a long time after they had investigated the situation in the village, so it was the best time to set up the array.
If they were to set up the formation at this time, it would definitely alert the people around them. Although the people of the cloud Sea realm had deliberately forgotten about the Hidden Cloud Village, they hadn't really forgotten about it. The appearance of Zhao Hai and the others this time had shaken the cloud Sea realm too much. The cloud Sea realm wouldn't let go of any place, so they would definitely investigate the Hidden Cloud Village.
