Luke and Frank didn't immediately fly up, but hovered in the air outside the building.
At that moment, in the underground parking lot of a nearby building, the back of a van suddenly rumbled. Two huge oval shadows suddenly broke out of the van, trailing flames behind them. They then turned and flew straight up.
A car had just reached the exit of the underground parking lot at that moment and was about to make a turn.
Two shadows flew past with a loud bang, the massive shock wave making the driver dizzy and shattering his front windshield.
After a long while, he finally regained some of his hearing, and couldn't help but curse. "WTF! What the hell was that?"
But right after that, he heard a huge commotion outside the exit.
Many people were crying out in alarm and screaming, and there were crashing sounds, followed by… a violent explosion?
Stunned, the middle-aged man got out and ran to the exit to see what was going on.
