Within, there emerged densely packed threads of principle, filled with a destructive aura.
It seemed as though a random thread of principle possessed the power to destroy both heaven and earth.
The Dead Rule!
Instantly, Zhou Sui's pupils constricted; he sensed that the principle contained within the Immortal Slaying Flying Knife was very familiar, as if he had seen it before, and then he remembered—this was the Dead Rule.
After all, he had condensed the Eye of Straight Death, and this Heart Eyes could perceive the Dead Rule and see countless threads of death.
Thus, he was extremely familiar with the power of the Dead Rule.
No wonder the Immortal Slaying Flying Knife was so terrifying—it contained the Dead Rule.
Therefore, it was capable of killing immortals, causing many immortals to spill their blood and their souls to scatter.
"This Immortal Artifact is indeed very suitable for me."
Zhou Sui was very excited.
