"Huh!?" They exclaimed.
"It is reasonable though, the defence I put in the skill is unreasonably high. And mind that it still grows," Joan explained.
They were in thoughts. A one-second skill has such huge mana consumption while it was still in its young stage. Making them think again on its name "Invulnerable". As they thought about it, they can't help but chuckle. It would be reasonable too to put it on Grandmaster rank. It was soon, they chuckled.
"I will master this skill to the fullest as my priority. Thank you Joan for being the first to lend it to me," He bowed his head.
"No, don't bow. I have many things to make too in the future. You are a test subject and I am your researcher. We are on equal grounds. You help me and I help you, that is," Joan said unperturbed.
He then shook his hands instead, he still was grateful to Joan even with everything he said.
"Next is Kenji of the Ronin department," Joan announced.
