When Karsha opened his eyes, he saw Yi Ran standing up from her meditation posture. He also sensed a sharp aura circulating around her body. Looking at her fairy-like appearance and the intense aura around her, Karsha felt both happy and threatened.
Happy because his woman had gained something from his sword dance, and threatened because the current aura around Yi Ran showed she had become several times more powerful and could end his existence within a few moves.
He needed to get stronger. It was his job to protect her, but with the enemies he was making and those yet to come, his woman would be the one saving him. He wasn't jealous, just motivated.
He wanted to challenge her to a sword fight at that very moment, but before he could make any move, the King appeared before him, startling him.
