What's it like being an undercover agent sent to the Ninth Heaven by an alien immortal, wielding the Anlan gun? Collect golden bulls? Collect war chariots? Collect immortal shields? Then collect the complete King's set. Drive the King's Contempt. Sing the King's Song. Summon the King's true form. Fight your way into the Ninth Heaven and wipe out a bunch of traitors? It seems...it's not impossible!
