Li Yao, although he often said he didn't care about equipment and wouldn't waste time on low-level ones, when it came to a Divine Artifact, there was no such thing as wasting too much time.
Even if it delayed his leveling, if he had a clue about a Divine Artifact, he would spare no effort in pursuing it.
You must understand, in the later stages, Dark Gold equipment, although precious, isn't very hard to come by. Kill high-level bosses, or if you have enough money, you can always buy Dark Gold Legendary Equipment of similar quality.
But Divine Artifacts are different, they are not something that can be obtained just by talking about them—they are truly rare treasures.
In The Ancient God World, peak Legendary Equipment and Divine Artifacts are never abundant, basically, each one is unique, possessing a history of its own.
