Continuing to walk through the entire place, Finlay and Serko showed Arthur and the others all their works from the very first prototypes to the latest versions they created. Each iteration and each version would be better than the previous one and more polished.
They improved the main wings, the main body, the design, and even the energy consumption. However, they still faced one massive problem. No matter how much they improved the design, they simply didn't have enough monster cores to make it run properly.
"How many monster cores does it take for these aircrafts to actually fly out of the forest?" Arthur asked the two as he ran his hand across the wood with a thoughtful look.
"... We don't really know. Our calculations say that… It requires a lot. Potentially hundreds or even thousands of weaker monster cores to fully fuel this craft for long enough to leave the forest." Finlay replied.
