Yin Wei was laughing heartily now. He had fooled Ji Yuan into expending his most powerful sword art.
If he had been struck by Ji Yuan while he was diverting his profound strength to his attacks, his profound defenses may not be able to tank the full profound power of Ji Yuan's attack.
But at the same time, he knew that Ji Yuan would not be so foolish into expending his precious profound attack in a random attack. He obviously knew that Ji Yuan is always quite calculative when he is in a fight.
But he had an advantage that Ji Yuan did not know and that was his super metamorph form that could triple his profound defenses.
