To win over this Nine-Headed Demon Saint, Lin Fei decided to put something valuable on the line.
A lower-grade immortal artifact.
Even to an Eternal Giant in the human immortal realm, this was worth a considerable fortune.

Not only that, but this silver longsword also contained a unique power of immunity.
Lin Fei had previously forged this lower-grade immortal artifact with spell-banning mithril to improve his
