Although Master Liu hadn't fully mastered the Teleportation Technique, he was quite adept at Sword Control Technique.
Otherwise, he wouldn't have used the skill so effortlessly.
This was also why he seemed quite inept in the application of Dark Energy.
It's not that Master Liu wasn't diligent, but like Ye Cang, he devoted all his energy to this kind of "Cultivation" related Dark Energy Technique.
The silver treasure sword he used was one of the nine Mountain and River Swords Ye Cang obtained with contribution points.
Although they were twenty years apart in age, they shared a common interest.
So, recently on Dragon Sleep Mountain, the two would often discuss cultivation experiences together and had a good relationship.
This was why Ye Cang gifted Pei Laoliu a Mountain and River Sword.
