Artifact Refining is categorized into ten grades.
Mortal Instruments are First Grade, Treasure Instruments are Second Grade, and Heavenly Instruments are Third Grade.
Spiritual Artifacts, which are in a league of their own above Heavenly Instruments, are Fourth Grade Magic Artifacts!
Beginning from the Spiritual Artifact stage, spiritual endowment is required, and the difficulty of the refining process increases indefinitely. Even in the Immortal Domain, it is quite a luxury for a Cultivator in the Golden Core Realm to possess a Spiritual Artifact.
And yet, in the display cabinet before him, there was a Spiritual Artifact.
Though it was a defective item with numerous flaws, this object already possessed a spirit. To think it had been left in this museum for who knows how many years was a sinful waste. Of course, it was nothing compared to the Immortal Artifact that Ruan Tang had used for flower arrangements and later gifted to Xu Yaoyao.
