In his grasp, was the green square leave. Inside of it was the gun powder and the small flat marble.
"Watch it, Pan! I hope you'll be amazed by this."
As soon as he spits these words, he stretched his arm then throw that stuff at the rectangle marble in front of them.
BOOM!
When the moment it made a contact. A strong explosion transpired in the working station. Its force was strong enough to destroy the rectangle marble, at the same time, crumbling the entire place.
In front of them, was the thick dark smoke that enveloped the place, aside from that, they could smell the gun powder.
Pan's jaw was dropped, his eyes widely stretched as he was astonished by this occurrence. Aside, he didn't anticipate that square leave can make a strong explosion that could kill several people in just the blink of an eye.
