Mother-Empress and Fiance Ruined My Core; I Slaughtered Everyone

The Phoenix Clan had one law: whoever cultivated into the golden phoenix would rule the clan. To win my mother the empress's favor, I sealed myself away to cultivate, enduring searing pain as I evolved and transformed again and again. But just as I was becoming the golden phoenix, a group of people broke through the cultivation chamber and, while I was defenseless, struck to destroy my spiritual core. Not only did my evolution fail, but every drop of my spiritual power was drained away, leaving me a cripple.
