The sun herders on Sun Ship flew into midair and surveyed the barrier that shrouded Sun Well anxiously as though a great enemy was arriving.
The barrier of Sun Well was formed by the rays spewed out from the well, forming a light body of a hemisphere. It covered the Sun Well and formed a heaven and earth with a radius of several hundred yards.
Qin Mu had never been to Sun Well, but he reckoned that there had to be a trick outside the light hemisphere to conceal itself so it wouldn't be eye-catching and would not stand out. Otherwise, news of a huge golden ball shining radiantly in Great Ruins would have long spread throughout the place and even to the outside world.
Fengdu was somewhat similar. It would only appear at night, and it couldn't be seen at all. One could only go into it by chance and coincidence.
