Right after he put the last one on, his teacher waved his hand and the torches on the wall went out.
He moved around trying to adjust to the weight because he knew that he was about to have company and moving so stiffly could cost him his life or a limb.
However, he didn't get much time, before several mana beasts streamed through the entrance.
He sprinted out of the way with some difficulty and made his way towards the corner where he activated 'Hidden Presence'. He stood as still as possible, because even though the beasts were only red cores there were a tremendous amount of them and if he got noticed he would surely die. Conserving mana was important, but 'Hidden Presence' didn't use that much mana and not moving kept the amount of mana used to a minimum. He realized from that short sprint that training with the extra weight was going to be much harder than he originally thought. He was slightly winded from running just a few steps.
