Qu Jianlei had examined celestial bodies for so many days that he naturally knew some of them contained natural caves.

Natural creations and artificial creations did have differences. Perhaps some people could conceal them exquisitely enough that they would not be easily discovered.
But once one reached the Supreme level, the sixth sense became much sharper. It was not difficult to notice when something was wrong.
