This was different from what he had imagined. It was undeniable that Chu Yunfan was the most terrifying opponent he had ever met in his life. He had never met such a terrifying opponent.
Chu Yunfan's swordsmanship had reached a level of god-like mastery. Any simple sword technique could be transformed into something magical in Chu Yunfan's hands. On top of that, his mana was like the sea, unfathomable and endless. After fighting for so long, even the khan, who was in his half-demon form, was struggling, but Chu Yunfan did not seem the least bit tired.
What kind of terrifying monster was this? It had no weakness!
