I Defy the Sky with My Bones

The threshold for ascension in the Immortal Realm has skyrocketed every year, and the genius Lin Feng was ruthlessly persuaded to quit by the Immortal Sect because his spiritual root rating did not meet the standard. In desperation, he actually dug out his own innate Taoist bones, used the bones as pen and blood as ink, and created his own taboo cultivation system. From then on, the traditional immortal way launched an endless pursuit of him, but they were horrified to find that the more he killed, the stronger he became. Until one day, he bloodbathed the Immortal Alliance headquarters and pointed his sword at the heavens: "You say I am a demon? Then today I will become a demon and redefine the laws of the immortal world!"
