The moment the ground began to shake, Virgil and Hannah's group were forced to their knees by an absurd amount of power that came from a point a hundred kilometers away from the area they were training in.. but this pressure did not last long, and disappeared as quickly as it arrived.
This pressure was not imposed by physical means, like the effect that gravity would have on a person.. but by a psychological one, just like the feeling that a person would feel when encountering a being they had no chance defeating, or escaping from.
Right after the pressure stopped, Virgil weakly stood back up on his feet. Then, with trembling legs, he ran in the direction where the pressure came from.
"Where are you going?!" asked Josh in worry, after noticing the fearless figure of Virgil run straight towards the source of power, which to them, felt nothing but deadly.
