The Heavenly Life God?
Everyone faltered upon hearing this before coming to a sudden realization.
In this world, only a being with mastery over life could set up such a terrifyingly powerful death formation. After all, life and death were always interconnected.
The best doctors knew how to kill someone most efficiently.
The best pharmacist would also be the most well-versed in poison.
The more understanding one had toward life, the more they would be able to control death!
As such, it made sense that the Heavenly Life God had set up this formation.
