In the end, Ryan discovered that he could control around fourteen objects at the same time. However, he managed to find a way to overcome that problem. Using Earth Manipulation and Earth Transformation, he created something like a simple cage that could store fifteen of his battle machines. As long as he has mana, he can control fourteen of those. It consumed more or less one hundred points of mana per second, but now Ryan had under his control fourteen 'flying battleships,' and each one had fifteen battle machines.
"You sure had an interesting idea, but I think you could have made some adjustments and thus make everything more efficient. The design of the cages is brute as well."
"No one asked you anything," Ryan said. "Why are you giving me advice for design and efficiency? You are a dragon; you always try to overpower your foes with brute strength."
"Are you different?"
