This blood sacrifice curse mark looked like the simplest curse mark imaginable.
Though it was only a tiny mark, it was formed from countless lives and all their resentment.
This curse mark was also part of the curse.
When the Nine Heavens Alliance had previously researched the Death Swamp, they had proposed such a theory.
If ordinary power was useless against curses, then what if poison was used to fight poison?
What would happen if the power of a curse was used against another curse?
Thus, the blood sacrifice curse mark had been developed.
However, the blood sacrifice curse mark was still incomplete. Just as they had seen, a single use required countless lives.
The stronger those sacrificed were, the greater the blood sacrifice's power would be.
But this kind of curse mark was certainly unacceptable.
For if they used this curse mark, the Death Swamp might not even be destroyed before their own people were slaughtered first.
What no one had expected was that the Nine Heavens Alliance was still continuing to tackle the blood sacrifice curse mark.
For such a thing to happen to Luo Shen, he had gone completely mad before his death and actually used the curse mark.
The lives of hundreds of thousands were snatched away in an instant.
This was the power of a curse. Xu Zimo could sense it very clearly.
The negativity of hundreds of thousands of people fused into one.
Xu Zimo had originally intended to resist, but he did not know what he recalled.
He actually did not resist, instead facing the curse's power head-on.
"Rumble, rumble."
The curse descended, its immense power arriving with the force to destroy heaven and earth.
The blood sacrifice curse mark instantly transformed into a stream of light and entered Xu Zimo's body.
