C1447 Shen wenxin's sword

What was brought up on the auction platform was a sword.

More accurately, it was a light green jade sword. It did not have any exquisite decorations and looked very simple. The blade did not reflect any light and looked like countless strands of black hair had formed the shape of a blade. On it, two words could clearly be seen.

Blue hair.

This is one of the Elder Jiu's Azure Jade Seven Swords
