"Pops, can you make it on time?" Thirteen asked Gerald, who now had a troubled look on his face.
"I don't know," Gerald commented. "I've never made something like this before."
The father and son duo were currently looking at a rough blueprint which Thirteen had drawn an hour ago.
At first, Gerald thought that Thirteen had gone mad and was about to ask him to build an Attack Helicopter from scratch.
Fortunately, the blueprint was not the one in his head, but it was still something that he had never attempted to do before.
What Gerald was looking at was a Ballista, but it was not just any ordinary Ballista.
It was a Ballista that could "theoretically" launch a one-ton payload that could travel up to two miles.
