Wan Jun certainly remembered that sword technique, and one could say the memory was etched deeply in his mind. It was precisely because the Supreme Sword Sovereign had chosen to teach it to the Rogue Heart Sword Hero, who was his senior disciple, and not to him, that Wan Jun had felt dissatisfaction, leading to his mind being corrupted by the Demonic Qi inside the Seven-Star Dragon Abyss sword, ultimately causing him to commit the heinous act of betraying and murdering his master. One could say that it was this very sword technique that lit the fuse of the tragedy.
