From MC's perspective:
Abandoned building,
When the environment returned to normal.
Tremor!
The whole building starts to collapse. Seeing that I collected his corpse in the system space. The next second, I disappeared from the spot and started leaving.
When I appeared in the hall. I came across the ugly-faced wizard and other underlings.
"Gravity Blast," I cast the magic spell.
A wisp of magic released from the finger and shot at the target at a breakneck speed. The gravity magic blasts away the target's body into pieces.
In the blink of an eye, I took care of other things before leaving the place.
Rumble!
Not long after I left, the whole abandoned building collapsed onto the ground. The sound could be heard far away.
Soon, the place would be visited by authorities.
Meanwhile,
