And as long as efficiency increased, those spent Magic Stones would naturally be earned back.
Thinking thus, Colin walked up to the harvesting machine, looked up for a careful observation, and asked, "What's the energy consumption like?"
"Five ordinary Magic Stones can support it for about an hour," Shelley said. "Just getting those blade gears moving doesn't use much energy, and it's quite simple to make it happen."
"Not bad, but it would be better if the consumption could be even lower," Colin stroked the metal exterior of the towering machinery, "The cost of this harvester is still too high."
After all, it was a piece of Witch Tools, and Witch Tools were never cheap.
This seemingly simple harvester had, from start to finish, from materials to research and development, cost him at least a hundred thousand Magic Stones.
"Indeed, if we were to harvest wheat solely with these machines, the cost would far exceed that of using serfs to harvest wheat," Shelley nodded in agreement.
