a mysterious man is waiting at the main lobby table 

"When humanity is sitting here living their lives to the fullest, despite the fact that they don't deserve it, I find it incomprehensible that the emperor's embodiment is operating a store"

"Please tell me who you are."-byeon

'Oh, you don't need to know right away byeon because you will discover it shortly."

Byeon and Miyoung exhale in relief as the stranger gently walks away.

"It's a relief that he didn't want to fight or hurt us or else we would have died. He's strong enough that I'm not sure I can beat him even with your assistance, Miyoung" -byeon

"Well, that just means we need to continue training harder than ever byeon"-miyoung

"The problem is that I'm not becoming any stronger, therefore I need to find another way to do it if I want to be ready for the examinations"-byeon

"Try looking through your ancestors' library; perhaps you'll find something there that will make you considerably stronger"-miyoung

-at the library-

"All of these are simply manuals for martial arts that my predecessors wrote, and I have already mastered them" -byeon thought so

A key fell on his head as he was perusing the items.

"Oh, how did I miss seeing this before? Perhaps it will open the steel door that I had previously been unable to open"-byeon

A single sword with a black scabbard and a white rope-tied scabbard was set up on a pedestal as the door creaked open.

Byeon becomes stuck inside as the steel door shuts tightly as he enters.
