Refining Mortals and Killing Immortals

[Sword Way + Demon Way + No System + No Time Travel + Single Female Protagonist] In the Age of Ending Dharma, the gods disappear, all immortal spirits are destroyed, all races perish, the heavens become dim, and all living beings sink into the endless sea of suffering. Since then, the immortal path has decayed, the true dharma has been cut off, the universe is so vast, and there are no more true immortals. False gods and immortals are at a high level, and mortal lives are regarded as nothing. Until that day, an ordinary boy walked out of the mountains. Mortals can also practice demon magic, and their swords, bones and jade become gods. Heaven and earth cannot restrain my way, so I can refine this mortal body to kill thousands of immortals.
