Low Grade Immortal Artifacts are generally only something Nascent Soul Realm experts can bring to their full power.
As for Middle Grade Immortal Artifacts, the requirements for a Cultivator are even higher. Even experts at the Middle Stage of the Nascent Soul Realm might not be able to draw out their full might.
Ye Chen's current cultivation has only just stepped into the First Layer of the Golden Core Realm. Even if he obtained a Middle Grade Immortal Artifact, the power he could unleash would be extremely limited.
So, Low Grade Immortal Artifacts are already more than enough for him.
It's just that Bai Jing did not know that some of the top-tier Sword Arrays Ye Chen controls require Middle Grade Immortal Artifacts to be executed.
This was why he was so eager to obtain a Middle Grade Immortal Artifact.
If he had a full set of Battle Swords at the Immortal Artifact Level of Middle Grade, his strength would definitely receive a considerable boost.
