Exiled After Losing My Sword Bones, I Slay My Master to Walk the Righteous Path

This is a chaotic xianxia world shrouded by the prophecy of "slaying one's master and bringing the world to ruin." Lu Chen, an orphan whose clan was wiped out and who was born with a sword bone, has been imprisoned by his enemy, iron chains piercing his shoulder blades. As a string of bizarre murders unfolds, he is forced to descend the mountain with his master and falls into a deadly trap, despised and watched by everyone. After awakening a Cause-and-Effect Deduction System, he uses his lifespan as bait to retrace the crime scenes. With each broken chain, he draws closer to a bloody counterattack. The whole world is waiting for him to slay his master, but he will make fate itself change hands!
