Many of them had played with a ball in their childhood, and the Spirit Sphere in Evelyn's hand looked just like a glass ball. Even compared to the regular ones they had been playing with, it appeared even worse as a weapon!
When they had passed it by, many thought that whoever picked the stupid thing would be laughed at by the others for being a kid.
But of course, none of them dared to laugh now in front of the stern-looking professor.
It didn't take Evelyn long to discover how to use the weapon.
Apparently, the spirit sphere was used somewhat like a cannonball in this world, though the requirement of actually using a cannon was negated through the use of spirit power.
This, however, also meant that the user not only had to focus on controlling the explosive force that would propel the 'ball', but also carefully control its direction.
