The short man was none other than someone Ning Cheng had met back when he was on Yixing Continent carrying out tasks. At that time, Ning Cheng was still with Luohong Sword Sect and had taken on task number seventeen. The location of this task was a battlefield where two true nations were at war. After entering the battlefield, Ning Cheng encountered numerous talented disciples who had been frozen because of this task, and he also came across the Causality House.
In the Causality House, Ning Cheng successfully freed all the disciples trapped in ice pillars and even extorted Starry Sky Crystal Stones from the old air-like entity. The reason why he could intimidate the old air-like entity was that he used a spear technique called Traceless, making the entity think he was the reincarnation of some great power.
