Although Sophia's ship still had sails, the power for a vessel with a steel hull didn't rely on sails alone. At the bottom of the iron ship was something resembling a propeller.
After Sophia's explanation, Ronin learned that the principle was just as he had hypothesized: it used Magic Energy for propulsion.
She stated frankly that this type of power consumed too much Magic Energy. Unless it was an emergency, they relied on the sails for propulsion most of the time. Occasionally, they would also manually input Magic Power or Fighting Qi to drive it, saving on Magic Crystal Stone consumption.
Sophia was quite generous with this technology. She said that as long as Ronin could provide enough iron ore for Simon to repair their ship, Simon would build a Magic Energy-powered vessel for Ronin free of charge.
