566 No Mercy!

All cultivators, including Zuo Wuxin who was being attacked by Lin Feng, were puzzled why Lin Feng was only using the most basic Spirit Essence attack instead of employing a Spiritual Artifact.

It was well known that attacking with a Spiritual Artifact could multiply the attack strength many times over! It was incomparable to using just Spirit Essence!

Otherwise, there wouldn't be so many Spiritual Artifacts, nor would there be any classifications of their levels!

Could it be that Lin Feng didn't need to use a Spiritual Artifact to defeat Zuo Wuxin and that merely using Spirit Essence was enough?!

But, how could these people know? It wasn't that Lin Feng chose not to use one; he simply didn't know how to use one!
