All the Guardians present close to the core area already came to the sources of the energy fluctuations. They are unable to get close to those places. The moment they try to come closer to those areas, all of them begin to feel some kind of energy begin to affect their body.
Instantly all the Guardians begin to coat their whole body with Zen energy. The Zen energy present in their body is finally able to protect them from that unknown energy that previously began to affect their body.
However the problem is that they still cannot approach those sources of energy fluctuations even with their Zen energy, so it became very hard for them to approach those sources. It looks like some kind of thing is present there which is like a barrier.
This instantly makes everyone alert. Without wasting a single second they quickly inform their superiors about this matter. Instantly the entrance exam committee and The Guardian Association know about all this information.
