Exiled by the Scrapped Sword Bones, I Killed My Master with My Right Hand.

This is a time of chaos in the fairy tales shrouded in the prophecy of "killing the master and destroying the world". Lu Chen is an orphan born with sword bones, but he is imprisoned by his enemy with an iron chain piercing the lute bone. As strange murders occurred one after another, he was forced to go down the mountain with his teacher, and fell into a certain death situation amid the rejection and surveillance of everyone. Awakening the causal deduction system, he used Shou Yuan as bait to trace back to the scene of the murder. Every time he broke a chain, he was one step closer to the bloody counterattack. The whole world is waiting for him to kill his master, but he wants this destiny to change hands!
