The aura around Lan Shu was incredibly terrifying; the force of it even managed to slightly affect Chu Xiyue and Su Qingzhen standing behind Gu Yang, causing their hearts to pound anxiously.
Just as they thought this fearsome woman was about to strike, her aura suddenly receded and she became seemingly nonchalant.
She said, "I'm curious, where does your confidence come from? You should know, your half-baked 'God Destroyer Nine Styles' can't touch me."
Her tone suggested that she wasn't impressed by Gu Yang's previous ruthless move.
To some extent, Gu Yang's 'God Destroyer Nine Styles' was indeed unorthodox, since he had not cultivated the 'Heavenly Elemental God Slaying Art'. However, not everyone at First Rank has the right to say that.
Gu Yang could feel that Lan Shu's cultivation level far surpassed his. If they were to fight, he would be at a great disadvantage.
However, since she didn't directly attack, it seems unlikely that she would.
