The Demon's Blade had detected Song Jian suspended in mid-air and Liu Qingyun a while ago, but it hadn't made any move, even deliberately concealing its aura.
"Once he's killed, the contract with him will be null and void!" The Demon's Blade sinisterly thought to itself, "And the curse he cast on me will be lifted with his death!"
The Demon's Blade has always believed that Song Jian had cast some sort of curse on it. As an Abyssal Demon, it naturally knew the severity of curses. Once the curse-caster dies, all the curses they had cast would gradually disperse over time.
The Demon's Blade was eagerly awaiting the moment when Liu Qingyun would behead Song Jian.
However, Song Jian's roar made it slightly panic. It didn't believe that it would die along with Song Jian, but evidently, Song Jian had the ability to disperse his soul upon acknowledging his impending death.
