"Very expensive?"
Gu Jinlai asked.
Liu Wanhu nodded: "An Immortal Immortal Instrument."
"..."
Gu Jinlai was momentarily speechless.
Immortal Artifacts, top-grade Immortal Artifacts, Supreme Immortal Artifacts, and even Immortal Immortal Instruments are essentially all about the utilization of the Power of Dao, so fundamentally there is no difference.
But even so, the value of an Immortal Immortal Instrument still matches up to thousands of ordinary Immortal Artifacts.
"Evil Gods occasionally erupt violently from the Heart of the Cosmic, and after undergoing the tempering of the Cosmic Heart, every surviving Evil God becomes extremely powerful. No Honorable Daoist dares to claim they can withstand the Evil God Power, so their asking price of an Immortal Immortal Instrument is not unreasonable."
On the side, Xue Yan added.
Gu Jinlai nodded.
