Booom—!
Large portions of the hall collapsed inwardly, crashing against the ground beneath them as the sound of a significant explosion reverberated through the air.
Boom—! Boom—!
The hall continued to shake, and dust continued to fly into the air, creating a veil that obscured what was taking place behind it.
In the midst of the veil, bright white lights flashed while muffled explosions accompanied them.
Each impact was felt throughout the entire headquarters, as buildings collapsed and the dome protecting the facility continuously flickered. Cracks soon started to form, and alarms started to ring.
This didn't last for long, however.
Silence soon returned to the headquarters in the aftermath of the short conflict.
A great number of figures were seen lying on the ground as they took their final breaths, and those that were still alive did not even dare to move an inch.
