Three days ago, the Su family, a prominent family in the south of the Yangtze River, was wiped out. Only a bloody wolf-tooth dart was left at the scene. Everyone in the world knew that it was the mark of the "Black Wind Hall", but only Ye Guying knew that the pattern on the dart was wrong - the real wolf tooth dart was engraved with a howling wolf, while this one was engraved with a tiny honeysuckle flower.
