Uh, You're Welcome?
William had originally planned to work on Earth Spells for half an hour, but a last-minute decision led to more than an entire day passing. During that time, he modified hundreds of different Spells. From improving his preexisting defensive Spells to developing variations of offensive ones, nothing was left untouched.
His Mana Reserves filled up only six hours into testing his Earth Spells, so William spent three quarters of it on two more Greater Mana Veins that were located near his index finger and a third located in the center of his palm.
94 million Mana went into the process, but in the eighteen hours that passed since then, 73 million had already recovered. In a few more hours, his Mana Reserves would be full again, so William spent another 30 million to add the Mana Point on the back of his hand.
