Hong Yu continued the presentation of the treasures by opening the royal blue-colored chest, there were Sword Rings, which are circular shaped blades made of yin black iron. These sword rings could be incorporated into the user's sword by strengthening the blade of the sword, besides, the user may have the possibility to create affinity with elements that have more Yin attributes, such as water and darkness.
Of course, these sword rings could strengthen other weapons or even be used to create a totally different weapon, but usually, sword cultivators devote themselves to cultivating their personal swords with everything they can, so when Hong Yu presented this item, he emphasized the use only in swords.
It is not even necessary to elaborate how green of envy the inner disciples felt to see this item is given to the novice disciples, they lamented not being of this new generation of disciples of the sect.
