Capítulo 501: I Don't Shake Hands

William almost turned white with shock, but he managed to maintain his composure. He thought about lying to the Professor, possibly even gaslighting him into thinking William's skills were another, but he knew its chances of success were close to none.

Professor Tenningbrew was an expert with the Illusion Element; William should have expected for the man to see through his Potential Spell.

-I know what you meant. I'm literally connected to you! It was a funny joke, why are you denying it?

It was funny?
