From MC's perspective:
I'm not using gravity mana except to exert physical strength.
In a few steps, I walked out of the range of the explosion site. At night time, only the spell attack collision illuminates the surroundings.
I didn't dare to turn back. Until I crossed a few miles. Slowly, I escaped from the complete range of the previous spot. But not long after, I sensed the presence of wizards hiding behind the rocks.
Starting from this place, the ancient bedrock is untouched here. I didn't want to alert them. So I changed my route and started escaping decisively.
Boom!
A blazing flame ball the size of a small building hits the ground not far away from me.
The next second, the aftermath sent a powerful shock wave all around. The shock wave turned the bedrock into rubble.
Feeling the massive shock wave coming towards me.
Swoosh!
I appeared in the Gregor Mansion.
