"So that's how it is."
"No wonder only Mahayana Loose Immortals can wield Immortal Artifacts."
"Immortal power is the foundation for using Immortal Artifacts, the essential energy source for them."
Zhou Sui was utterly astonished in his heart.
This was also the first time he had used an Immortal Artifact after ascending to the Mahayana stage.
One could say that at this moment, he could truly unleash the full power of the Immortal Artifact.
Previously, when he used mana to activate it, it was like a pony trying to pull a heavy cart—extremely arduous.
Without his exceptionally profound reserves of mana, it would have been utterly impossible to activate it.
But now it was entirely different.
With his mana having transformed into immortal power, the energy within his body had ascended to a new tier.
This allowed him to easily activate the Immortal Slaying Flying Knife.
As a result, the artifact's power could be fully unleashed.
