'What grade of Magical Artifact is this? I can't even tell.'
Whether it was a Magical Artifact, a Spiritual Artifact, or even a higher-grade Magical Treasure, its actual grade could be determined as soon as it was activated.
For example, when a Spiritual Artifact was activated, a layer of Spiritual Light would be clearly visible on its surface. The brighter the light, the higher the Spiritual Artifact's grade and the stronger its Spiritual Attribute.
In contrast, a Magical Artifact was just a cold weapon, with no Spiritual Attribute to speak of.
The difference was even more obvious for Magical Treasures, which were a tier higher, as they had already given birth to an Artifact Spirit and possessed Spiritual Wisdom.
However, the Tai Chi Diagram in Feng Wuming's hands was very strange. When activated, it emitted a bright Spiritual Light, yet Song Changsheng couldn't sense the expected Spiritual Attribute.
For a moment, he found it difficult to determine its grade.
