"You—what was that?!" Adel exclaimed in shock.
What he sensed was a split second of sharp wind infused with sword intent. The force of the wind alone was enough to sever his forehead if it had passed his head. His eyes trembled as he stared at Elena's power and technique. How was she able to send a strike strong enough to kill him without even circulating any energy?
He had already thrown a special poison powder called "Mortal's Experience," which was designed to halt all energy circulation in a cultivator's body for a certain period, depending on how much they inhaled. Mortal's Experience was sometimes used by assassins to render their victims helpless before killing them, depending on the circumstances.
