As the anticipation in their eyes grew, the ground-to-air missiles streaked towards the cannon suspended above the crossroad, trailing a long tail of flame!
However, just before they hit the target!
The floating cannon suddenly vanished into thin air like salt scattered on snow, as if it had never been there.
The missiles then collided with each other in the air, setting off a chain of explosions!
Just like huge fireworks!
Making this fireworks show even more spectacular!
"What... it's gone?!"
In the control room.
A group of people stared at the screen in disbelief, wondering how the cannon could have vanished so suddenly.
The unwelcoming cannon had been wreaking havoc in the city for quite some time now.
However, it would only appear for a maximum of thirty seconds before relocating to another part of the city.
This prevented them from ever locking onto the cannon as it would keep changing positions before they had a chance to do so.
