The Blood Sacrifice Curse Seal appears to be a simple seal.
Although it's small, it's composed of countless lives and grievances.
This curse seal is also part of the curse.
Previously, when the Nine Heavens Alliance was studying the Death Swamps, they proposed a theory.
If ordinary powers are ineffective against the curse, what if poison could fight poison?
What would happen if the curse's power was used against another curse?
Thus, the Blood Sacrifice Curse Seal was developed.
However, the current Blood Sacrifice Curse Seal isn't perfected; as was just seen, it requires countless lives for just one use.
The stronger the person sacrificed, the greater the power of the blood sacrifice.
But such a curse seal is certainly untenable.
Because if this seal is used, it's feared that they'd kill their own before the Death Swamps are even destroyed.
What surprised everyone was that the Nine Heavens Alliance continued to work on this Blood Sacrifice Curse Seal.
