Why?
Because this was refined by Gu Yuan himself; it is his Lifebound Flying Sword, and of exceptionally high quality, refined mainly using three types of the Nine Great Divine Golds.
As long as Gu Yuan advances to Primordial Spirit True Immortal in the future, he has a chance to refine it into a Spirit Treasure.
Therefore, with the Primordial Jade Scenery Sword, he doesn't need this Wu Hook Flying Sword at all.
Besides, the Wu Hook Flying Sword is somewhat damaged and is a Demonic Treasure. Gu Yuan now has the Black Dragon Halberd and the Primordial Jade Scenery Sword for attack, and the Nine-Dragon Furnace and Blazing Carp Shuttle, which are both offensive and defensive. Where does he have time to refine this Wu Hook Flying Sword?
So, selling it to exchange for other useful items is the best choice!
Not long after, the door opened, and Zhuang Zhong hurriedly came in alone, closing the door behind him with a cautious and careful demeanor.
