Immortal Artifacts, like Spiritual Artifacts, are divided into different levels. This pair of sword and saber should be the most ordinary lower-grade Immortal Artifacts. Above them, there are middle-grade, top-grade, supreme-grade, and even higher levels of Immortal Artifacts.
For example, the Cangsheng Seal in Chu Fengmian's hand, originally in the hands of Emperor Donglin, was never cultivated using the Emperor of All Living Beings technique and couldn't recognize a master to exert its full power. It was much more powerful than that Trident. The Cangsheng Seal, even among Immortal Artifacts, is considered outstanding, at least a top-grade Immortal Artifact, perhaps even a supreme-grade one.
However, even the lower-grade Immortal Artifacts are much more powerful than heaven-grade Spiritual Artifacts.
Unless it is a Spiritual Artifact with the ability to ascend and transform, they are far inferior to this pair of sword and saber.
