As the Grey-Faced Buzzard slowly made its way along a new route after leaving Planet Constlac, Gu Ding and his crew had yet set where their new destination was. Moreover, the matter of Robert needing Energy Crystals was still under discussion.
"Neptune, can't we use an alternative energy source if we aren't able to find the Energy Crystals that Robert needs?" Gu Ding felt that it was easier to find an alternative rather than pinning their hopes on Energy Crystals that they had no clue about.
"Theoretically, it's feasible. That's because intelligent life forms like them should have an intelligent energy conversion system in their body. It's just that it's been a long time since the Middle Ages and the present time. Most types of energy ores we have now are completely different from the ones of that era. Therefore, I'm not sure if his body's energy conversion system is compatible with them." Neptune thought that the idea was feasible.
