No one was even able to estimate how terrible the power of the Night Regime was. Even the elders of the Nine Temples had been shocked by the fighting prowess of the Night Regime.
At that time when the Dark Emperor unified the Middle Realm, the Night Regime was rarely activated. Just based on Jun Wu Yao alone, he had completely suppressed all the forces in the Middle Realm. Hence, no one could be sure how powerful the Night Regime really was. After the Dark Emperor had "fallen", the Dark Regions and the Night Regime also disappeared for a long time. Only those who had crossed them in battle knew the truth but….no one survived to tell the tale. It could also be said that for those who had personally witnessed the strength of the Night Regime, the grass on their graves had already grown to be taller a person.
