章 75: Flabbergasted Sierra

'Can you tell me more about it?'

[I can't tell details because it's random. However, you will spend a maximum of 4 hours after entering a dungeon doom. Should I activate the dungeon key now?]

'Wait,' Arkhen said before he turned to the girls.

"Let's quickly finish today's training. After that, I will be away for four hours," Arkhen said to the girls who were talking to each other.

*Beep…*

Suddenly, Arkhen's phone rang, and he saw that it was an unknown number.

Arkhen—, "Hello?"

Sierra—, "I am Sierra. I had a reason when I told you to spar with my aunt. I had decided that if you win, I will train under you because I need to beat a tough opponent soon."

Arkhen—, "Haha, then come to private training hall no. 13."

After saying that, Arkhen cut off the call and turned to the girls. "One more person will join us in today's training."

"Who?" Zoe asked curiously.

"Sierra," Arkhen said with a grin.
