'I need to be more careful…' Harry thought. 'Being reckless would bring nothing more than trouble for me.'
Unlike other people, he didn't use mana, neither did he use spells. He was anything but normal.
Though he had a skill that created an illusion of mana flowing within him, it didn't change the fact that he still didn't use mana.
He was currently too weak and acting recklessly could land him in a pile of trouble.
If the world discovered that he could cast 'spells' without the use of mana, they could experiment on him or even worse, consider him as a threat or a different race and try to eliminate him—with how weak he was currently, they would probably succeed.
"That's impressive… I've never seen someone channel mana so fast." The instructor said to Harry with a gentle smile on his face.
