Tyrant Sword.

"What do you think you're doing?" The disciple asked. He kept an eye on Su Hai and Zi Ya as he turned his attention to Li Jun and pushed out his hand. 

Li Jun felt a blast of invisible energy push against his body and force him backward by a couple of paces. He drove his feet into the ground and came to a stop as Zi Ya pushed out her hand and did the same to the Supreme Sword Sect's disciple.

Li Jun took the opportunity to rush forward. A sixth-stage martial artist leaped forward from the group, attempting to overpower Li Jun with a powerful sword strike. However, Li Jun stepped aside and drove his knee into the man's stomach. He dropped to the floor and gasped for breath. 

Su Hai carefully observed as Zi Ya and the eighth-stage disciple got into a pushing match and tried to overpower each other. She had to make sure that none of the other disciples were targeted as the fight erupted.
