It was fortunate Duan Ling Tian was not here. He would have been horrified if he saw the young man attacked the middle-aged man. This was because he knew these two people. Not only that, but he knew they were master and disciple.
The young man who was covered in pure Devil Qi looked extremely evil. He was Su Li, a very good friend of Duan Ling Tian when he was young.
Duan Ling Tian could still remember the first time they met. It was at the camp for prodigies in Iron Blood City of Crimson Sky Kingdom. Back then, both of them were in their teens. Later on, both of them passed the test in the camp for prodigies and entered the Paladin Academy of the Crimson Sky Kingdom in the Imperial City.
