Hearing Zhou Chu say this, brilliant light flashed wildly in Qin Fengming's eyes.
A powerful object capable of easily slaying a cultivator at the Ghost King stage—Qin Fengming had scarcely needed to think before he was certain what it was.
In the lower realm, among powerful objects that could be said to possess the absolute strength to slay any existence at the Ghost King stage, there could be nothing besides a Chaos spirit treasure.
Qin Fengming had personally activated a Chaos spirit treasure once before, and he knew firsthand how terrifying it was.
That time, he had activated the Purple Light Dragon Soul Lament. Although the Purple Light Dragon Soul Lament ranked near the bottom of the Spirit Treasure Ranking, its terrifying power had been beyond Qin Fengming's imagination.
At that time, his main body had perhaps activated less than one-tenth of that Chaos spirit treasure's power, yet it had easily slain three Great Cultivators. If an existence at the Ghost King stage activated a true spirit treasure, then slaying an existence at the peak Ghost Lord level could be said to be utterly foolproof.
Of course, the Vast Desolation Profound Treasure could also easily slay an existence at the Ghost King stage. However, based on Qin Fengming's understanding, merely activating a trace of the Chaos spirit treasure's might had consumed several drops of spirit liquid. Judging from this, an existence at the Ghost King stage might be able to activate a spirit treasure, but absolutely could not activate a Vast Desolation Profound Treasure.
