The Evil Cultivation incident in Guming County was classified as a Red Grudge Level event. The Five Sects joined forces, but the Red Heart Sect still suffered a devastating blow. Even their Sect Leader, Zhu Hong, a Martial Artist at the Peak of Innate, was grievously injured.
As for the highest classification, a Dead Sea Level event, if it were to spread, could turn an entire Dao Mansion into a veritable Sea of Death. Since the founding of the Great Wei dynasty, such incidents have rarely occurred.
It was hard to imagine how terrifying a Technique capable of single-handedly resolving a Dead Sea Level event must be.
