My name is Su Mu, I am just an ordinary blacksmith apprentice. My biggest wish is to forge a famous weapon that will be handed down from generation to generation.
On the day the city fell, my master died tragically, and I hid under the forge and shivered. In despair, I remembered Master's warning - the "Blood Soul Stone" buried deep in the ground and exuding an ominous aura must not be touched!
In revenge, I dug it up and threw it into the forge.
Flames soared into the sky, divine thunder came to the world, and I forged a magic knife that was completely black and covered with bloody lines.
