"Well… what are we going to do now?" Darya asked. "The only way to discover what is going is to use the purple crystal or talk with my grandfather, and I guess none of those situations will end well."
"You are right… if your grandfather can make a harvester run away, we are no match for him." Leon said. "As for the master of the undead Trent, he received a massive pool of mana, and that made him an obstacle impossible to defeat in his domain."
Leon wondered if he could create a magic item that could store his mana, most of the time, he was practicing his spells, strengthening them and making good use of his recovery. However, it looked like a good idea to store his mana in an object, maybe to use as a bomb of mana, or perhaps to restore his own mana in the middle of a complicated battle. The problem was, he had no idea how to do that. Leon created thousands of magic items so far, and none of them had such skill or effect.
