Stacking
Hao Xuan could feel the sword shaking in his hand. It felt alive, happy and ecstatic upon seeing its enemy writhing in pain. And it wanted more, desired more bloodshed and death that was caused by it and it alone.
And he was more than happy to oblige. The sword aura surrounding the blade became sharper with every swing. Its reach also increased but Hao Xuan realized that it was fighting him for control.
Rather than listen to him it was taking a life of its own and even trying to enforce its own will.
And then everything around him began to slow down, eventually even himself. His vision suddenly flashed with a blinding light and the very next second he found himself standing in a colorless shapeless world.
In the front was a copy of him staring back. Its eyes were empty and soulless but Hao Xuan knew what it was.
"You are the sword clone created by my Sword Dao? I knew this was a possibility but...I should be offended, right?" he mocked through gritted teeth.
