The sudden spiritual fluctuation makes everyone become very alert. Looks like this even made some of the students become more scared.
But most students just ignore those students. Naturally, everyone becomes curious to know why the sudden spiritual fluctuation appears in the place.
Before they could predict anything, the ground began to shake violently. Immediately, all the students begin to use their spiritual energy to make themselves stabilize.
All this time, they are using observation techniques to make sure that they do not get attacked by any enemy.
Because of this, sometime later all of them noticed some strong presence. It did not take them that much time to understand what was happening.
Fortunately, the earthquake had already disappeared, but nobody cared about the earthquake. Everyone can already feel the presence of those monsters that are definitely approaching in that direction.
