Broken Daotian

I just want to cultivate immortality in peace, but the world doesn't allow it. When the demonic shadows all over the sky let out weird screams of "Eh-huh" and swallowed up everything I knew, I realized that before I can live forever, I need to bathe in blood. The sect was destroyed, and I was sent into the starry sky as a "fire". I woke up from the sinking, holding a broken sword and hanging a broken flag on my back. My former classmates, where are they now? Where did the world-destroying demon come from? This path to immortality has been cut off, so I will use the bones of the demons to pave another path for future generations!
