There are rumors in the world that there is an "unnamed ancient sword" hidden in the Sword Forging Valley. The sword has no edge, but it can cut off everything in the world. Eighteen years ago, the Sword Forging Valley was destroyed overnight, leaving only an orphan child who was adopted by wanderers.
Eighteen years later, young Gu Feibai walked around the world with a broken sword, not seeking fame or profit, just for one sentence - "At the end of the sword, can you see your true heart?"
With the sword in his hand, he asked swordsmen all over the world: What is a sword? What is Tao? What do I mean?
