The old cultivator from Heaven's Augury Mercantile Union said, "This tiny bell spirit artifact is top of the low grade, which shows its exceptional quality."
Lu Ye was not clear on how the quality of spirit artifacts should be classified, but a comparison revealed that the tiny bell spirit artifact had more than one restriction.
The long sword in his hand could also be barely considered a spirit artifact, but it had only one restriction, which seemed to be able to fortify the blade, allowing the long sword not to break easily during combat with an enemy.
The restriction in the sword was actually a spirit rune, which someone had branded into the blade with a mysterious technique during its forging.
When Lu Ye faced his enemies, he only needed to channel his spirit force into the long sword to activate this spirit rune, sparing him the effort of constructing it himself.
