It was the Soul-crusher Blood Claw!
A bloody aura washed all over the place as the claw traveled, immediately conjuring a blood-colored specter in midair. That blood-colored specter was so overwhelmingly frightening that it could overpower nature itself. Every bit of the bloody aura in it contained raging, terrifying power.
That attack would've actually made one feel as if they had nowhere to run. They would've felt as if they were facing certain doom.
Lu Xuan remained unfazed and simply let the claw attack come at him. Cracking noises were heard everywhere around him as the surrounding air was shredded, causing even space itself to vibrate and become slightly warped.
