During his two previous meetings with the Dragon King in the Four Noble Truths Temple, the Unique King could tell that there had been an obviously vigilant and unconvinced look in the Dragon King's eyes. He had thought, 'Clearly, this guy still vividly remembers the palm strike I gave him in Heaven's Pass.'
But back then, the Dragon King had received that palm strike before he could whip out his saber. Like all killers with quick reflexes, he had fled as soon as he had sensed danger. The Unique King thus believed that the Dragon King had been subduing an urge to prove his sabersmanship skill all along.
