After crossing over, Ethan had a  book .

After studying it, he found that he could record the skills that he had seen the entire release process in it.

So...

Ethan used [Disarmament], and the effect was excellent. Now no one could cut him with a knife.

Frelian: "This is indeed a kind of magic."

Ethan used [Calm], and the effect was excellent. The "Sword Princess" who had gone crazy due to drinking quickly calmed down.

Hestia: "This does look like magic."

Ethan used [Hypostyle "茈"], and the effect was excellent...

"Wait, you call this magic?"

"Yes, this is magic." Ethan said.
