Sucked by the dark void

Seeing Gao Lan Mei's facial expression as she continued to chant, Ma Fei Hong vowed to get even later. She got scared for nothing!

Still, where does Gao Lan Mei plan to bring her? Though confused as Ma Fei Hong does not have any idea on what will happen next, it still does not remove the burning hope on her being.

From the time, that Ma Fei Hong realized that the magical transportation circle in the palace would not work, she already felt useless as a part of Justice Affairs.

Transportation circles are only meant for sky travel. How can you travel somewhere if there is no open path or space? Add to the fact that the next destination should also have the same matrix on the circle for coordinates.

These are the reasons why casters do not entertain the idea of underground traveling because there is no open path. Unless you dig an available space, which someone can just teleport into.
