Cast Aside by the Sect, I Slay the Immortal Emperor

The Xuantian Sect cast Xie Chenxiao aside like a weed, crippling his dantian and expelling him from the mountain. He carried a broken stele from the ancestral hall into the wasteland, using his blood as a guide to cultivate the forbidden 'Slaying Immortal Scripture' in reverse. Bai Shuanghe secretly protected him, Yun Jiuyou paved the way with blood arrays, and the mute slave Ayan inscribed his soul into a sword. When the Immortal Emperor's head hung atop the ancestral hall, the heavens trembled—for the so-called Heavenly Dao was but a lie woven by the imprisoned remnant soul of the Immortal Emperor. And the one who slew immortals was none other than the sealed progenitor himself. — Description from novelcodex.org
