"No, how could he know?"
Yun Xiao's appearance beside the black cloud mist undoubtedly stirred up a storm in Xue Qi's heart. Unlike the somewhat clueless observing cultivators, she was roaring inwardly.
Only Xue Qi, the caster of the Netherworld Finger, knew that the black cloud was the essence of the Netherworld Finger. As long as the black cloud remained, even if her body was destroyed, the Netherworld Finger would continuously absorb Heaven and Earth Energy and launch attacks on the enemy.
Xue Qi had never used the Netherworld Finger before, but she had seen her teacher, the Empress Canglong, use it.
On that occasion, she clearly saw the enormous black cloud continuously dropping pitch-black fingers for three days and nights, and the black cloud's energy did not dissipate at all.
That is the so-called unending absorption of power from the world, turning into the fuel to form the Netherworld Finger, as long as it is not artificially destroyed.
