The Heavenly Fiend Great Demon must have originally had an Artifact Spirit, but it either got damaged or was forcibly stripped away.
When Xu Fan first obtained the Heavenly Fiend Great Demon, it did not contain an Artifact Spirit, but now an Artifact Spirit has been born within the Heavenly Fiend Great Demon.
Indeed, Spiritual Artifacts are spirited.
Xu Fan casually swung the Heavenly Fiend Great Demon without using Spiritual Power, yet the fierce Sword Qi it emitted directly tore through the air, creating a black slash.
The power of the Spiritual Artifact was terrifying indeed.
The other swords at this time were trembling even more violently, wailing with a clinking sound, having all submitted.
"Haha...."
Xu Fan laughed heartily, feeling that his trip here was truly worthwhile.
He waved his hand, recalling the Heavenly Fiend Great Demon back into the Storage Ring and turned to leave.
