Turning an enemy into a friend

Buried Ghost Sword was not a true treasured Tool, but rather a secret technique. It was rumored that Changsun Liang had obtained it in an ancient site, and he was the only one who could cultivate this technique.

That was because when he entered that ancient site, his spirit had been strengthened by an ancient object, or rather fused with it. Anyways, even the great elites of the Black Moon Sect could not understand what was going on.

All in all, after cultivating this celestial technique, a small figure would appear from the middle of the forehead, brandishing two swords, and its might was incredibly frightening.

…One only had to sustain a single strike, and it was able to directly destroy his soul, and send him straight to the underworld!

It was capable of even burying ghosts, what more mere humans?
