The Divine Nine Demon Sect, under the Demon Emperor's orders, sends Yu He to assess the Ancient Countenance Cleansing Sect's head disciple, who is engaged to the Demon Emperor's direct disciple. The visit involves an insulting test of the head disciple’s skills, which if failed, will break off the engagement but with compensation. This leads to a challenge being issued and a battle being prepared. The head disciple, despite criticism, chooses a seemingly ordinary fire stick as his weapon, defying expectations.
