The Death Aura within the sword was meant to mask the Undying God's body's connections to itself, while the Darkness aura was the destructive power that fought against his body's ability to remove the Death Aura.
It also exploited the connection, forcing the connections to overload on themselves, destroying them.
That was the basis on which the sword had been created. That was the aura that was placed into the sword.
But something was different. The sword wasn't what he had tried to make.
The tribulation had put it through a mutation. Something within the sword had changed. Both Death and Darkness were much more violent.
And because the sword was made to manifest those on its physical body, even grabbing it was affecting Steelmind.
Steelmind couldn't let go of the sword at all. The moment he had come into contact, his Qi was violently being ripped away from his body, forming a connection that kept him from letting go.
