That's right, this old friend was the [Equipment Fusion Stone]!
Not long ago, he had obtained one before.
However, that one had been a Rare Grade fusion stone, capable of fusing three pieces of Rare Grade equipment.
In the end, he had used the idle [Wind-Fire-Thunder Trident (Purple)], [Terokkar Violent Bear Armor (Purple)], and [Skull-Ringing Hammer (Purple)] in his possession for the fusion.
The result had been a Legendary Grade shield: [Windfire Thunder Violent Bear Roaring Shield (Orange)].
This fully demonstrated the randomness of equipment fusion.
At the time, Zong Shen had not actually lacked shields, because he also possessed the [Aurora Guardian Greatshield (Purple)]. He had even regretted not using that shield in the fusion instead.
But on second thought, it would have been useless even if he had fused that shield. Who knew whether adding a shield would result in some other piece of equipment or weapon? For example, a greatsword?
Fusion followed no pattern at all. At most, fusing three pieces of the same type of equipment gave a certain chance for the final fused item to be of that type.
All in all, this [Equipment Fusion Stone (Orange)] meant exchanging three idle Orange Grade pieces of equipment for an entirely new Golden Grade item. There was a certain element of gambling and exchange involved.
However, although Zong Shen did not lack Orange Legendary Grade equipment at the moment, he did not have much of it sitting idle.
Moreover, given the current situation, the combined value of three Legendary Grade items would not be lower than that of one Epic Grade item. Even if Zong Shen had no use for them himself, he could give them to the Warriors and heroes under his command to strengthen them.
Thus, this [Equipment Fusion Stone (Orange)] would not be useful
