Klaus stared at Lila with a smile on his face as he waited for her to make her move. His soul was now strong enough to support the Demon Killing Circle for the next 60 minutes, so he wasn't in a hurry.
"If you won't, then I will," Klaus said, activating the second form of his movement technique. The next second, after taking a step, he was in front of Lila, his sword swinging at her neck.
Boom!
In response, Lila's cultivation base erupted, pushing Klaus back 100 meters. He staggered back a couple of steps, but a grin appeared on his face.
"You are much weaker than I gave you credit for," Klaus said, then moved again, this time stabbing at her with his sword. In response, Lila swung the short sword that appeared in her right hand, deflecting Klaus's thrust.
