Owen Bertram's location in the valley was plain in sight to the Mountain Master; he was looking to see if there was any ambush in this valley, or if any powerful beings were behind this kid.
Right now, he was very certain that only Owen Bertram was in this valley, revealing a cold laugh: what does this kid hope to achieve by luring me here? Surely he doesn't think that with his own power, he could challenge me?
Or perhaps he's naive enough to think that his status as a member of the Horizon Bureau General is enough to make me fear him, and negotiate with him?
"Hehe." He let out a laugh, resounding through the whole valley—he hasn't even entered the valley, and echoing laughs began to reverberate around Owen Bertram.
Like a Mind Control Sound.
Owen Bertram rubbed his chin, the laugh carried a hint of sharp Sword Intent, indeed it had the effect of a "Mind Control Sound", but why would you, the esteemed Mountain Master, plan to attack your enemy's strengths?
