บท 100: Chapter 100 - Challenge

"Sir, I would like to take this technique with me."

After coming to the ground floor, Allen gave the technique to the librarian. You have to say that when the librarian saw that technique he was quite surprised because he did not think that someone would choose a technique like this. 

"Are you really sure that you wanted to choose this technique? I think you already know about the technique and directly it won't help you fight anyone. It will only give you a passive ability. If you want to choose then you still have time and choose carefully."

The librarian said that to him. By hearing his tone Allen could naturally tell that he was also very surprised that he chose that technique.
