Activating his Draconic Eyes, Qingyi studied the flow of Qi around Mochen, quickly understanding how the Heaven-Piercing Demon Sword worked.
It used some Law to suck in the life force of thousands of living beings, gathering it around his body in a hurricane of crimson Qi that slowly converged towards the blade in his hands.
"Dangerous..." Qingyi muttered, his robes fluttering under the pressure of the power gathered by Mochen.
The rear lines of the demon army desperately retreated, trying to escape the reach of the technique, struggling not to become another sacrifice for their master.
Qingyi stretched out a single hand, opening it gently. His fire Qi exploded into orange flames, forming an ethereal, flaming spear in his grip.
Without hesitation, he hurled it towards Mochen, the surrounding air bursting before forming a perfect vacuum, creating a shockwave that swept away everything in its path.
