The possibility of becoming invisible, was a theory that people had long fantasized about.
Some wanted to test their theory by becoming invisible. However, most of the time, it was just evildoers who wanted to turn invisible so they could do evil things.
Or it could even be some pervert that wanted to be invisible to peek at naked women because they can never get one themselves with how trash they are.
Of course, it had always been a theory and no one had ever managed to come close to succeeding it aside from fantasy novels.
Thus, when Shi Tian learned that possibility was actually becoming close to reality, he couldn't help but feel emotion wavering.
"Master Isaac is truly no ordinary mechanic." Shi Tian exclaimed, feeling that Isaac Aaronax had long surpassed the term of a mechanic.
"Heh, if only you have heard of Mechanist Isaac's master." Mary suddenly muffled when she saw how excited Shi Tian was.
