Lord of Burning Wasteland

I was once the strongest Burning Heaven Realm Master in the Nine Heavens and Ten Earths, but I was stabbed through the heart by the most trusted person from behind. Three thousand years later, I woke up from the mortal world and became a handyman disciple of Xuantian Sect without spiritual roots. They destroyed my spirit, broke my bones, and threw me into a pile of dead people - then I opened my eyes, and there was a fire in the depths of my pupils that they had never seen before.
