The coffin didn't seem to have anything special about it.
Its entire body was black, as if forged from a very heavy piece of black iron.
The subtle aura emitted from it was the very thing that led Lu Changsheng here, emanating from inside this black iron coffin.
Lu Changsheng did not approach immediately; instead, he stopped at a hundred meters from the coffin, pointed a finger at the black iron coffin, and nine God Slaying Swords stood upright on top of it.
Simultaneously, as Lu Changsheng's fingertip skimmed through the air, killing arrays appeared around the coffin, enclosing it in three rings in front and three rings behind.
Then, he released a miniature Nine Netherworld Formation in front of himself...
The main body of the Nine Netherworld Formation is set in the Longevity World as a sect-protecting formation and cannot be moved arbitrarily.
So Lu Changsheng extracted part of it to carry with him.
