Duan Yun laughed heartily, even though he wasn't finding this battle easy at all. He was at the intermediate stage of the Martial Emperor Realm, and was among the best in the third-rank group.
This should have been enough to prevent anyone at a lower realm level from challenging him, but it seemed that Jiang Chen was fiercer than he had expected. It seemed as if he was inferior to Jiang Chen in the Sword Doctrine aspect.

Duan Yun knew well the Four Great Sword Doctrines, and he was sure that Jiang Chen's Sword Doctrine wasn't one of them. His was a type of Sword Doctrine that at first had seemed mediocre. However, in a confrontation, its power rose to an unimaginable level.
