I Hold a Blade, Questioning the Universe

The Blade Fiend died and was reborn as Gu Junhuang, the young master of the Heavenly Blade Sect. Gu Junhuang's experiences could be described as remarkable. The Blade Fiend thought his own life was full of calamities, but compared to Gu Junhuang's, they were nothing. His divine marrow was stolen, his blood was drained, his profound veins were dug out, and he suffered betrayal, falling into a land of the dead, where his spiritual consciousness was eroded and he was completely abandoned by heaven and earth. The Blade Fiend never believed in fate. Under the sacrifice of an ancient soul powerhouse, he was reborn from the ashes, using his blade to carve a path, battling the world, defeating immortal kings. With his long blade in hand, all heroes yielded, and the world ceased its wars. — Description from novelcodex.org
