The Black Blade's True Power

There was a strange sound that came as well as if something had been torn apart! 

When Ming Yue opened her eyes, they widened in shock as she saw something she wasn't expecting. 

"What... what is that? What did I just cut?"

She couldn't help but ask out loud, staring straight ahead of her. There was a thin black void where she had swung and nothing else. A part of her wanted to come closer and examine it but another part could only sense something uncanny about this thin void. The was no sound, no aura, nothing. 

But the void didn't last for very long, closing up after a few seconds. 

Ming Yue just stood there, dumbstruck as to what happened before looking at the weapon in her hands.

"You just cut everything. The air, the world, the very fabric of creation, you just cut it", Senior Zhen explained. 

The weapon spirit turned silent for just a moment.
