"Wait here, I have a few breakthroughs to finish first. Then we'll go out together."
Eska's gaze flickered as she watched Ryu vanished deeper into his immortal cave. He was the only one whom she had ever heard speak of breaking through so casually, he didn't seem to take it seriously at all. She thought that maybe things would change after coming to the True Martial World, but apparently not.
