Moreover, although the clear sky Island and the surrounding islands basically fit the layout of the Taixu xuanqing formation, some changes still needed to be made in order to let the formation play its role.
The most important thing was that the Liu family was building an airport on blue cloud Island, and the runway also formed an important part of the formation.
It could be said that if the runway had not been built, even if Xia ruofei were to observe everything from the same observation point, he might not have been able to sense the layout of the natural formation immediately. Of course, if Xia ruofei had stayed on the island for a longer time, he would have noticed something.
After all, the main body of the natural formation had already taken shape. Any subsequent changes would only be modifications to the foundation of the natural formation so that the formation could fully display its function.
