Among the three worlds of the Dark Camp, although there are countless strong individuals and notorious Demon Kings, the most famous is none other than the Great Demon King Satan!
This is not to say that Satan is the strongest among all the Creation Sovereigns of the Dark Camp; there has never been a real contest, so none of these claims hold water!
Moreover, the strongest individuals in the three worlds of the Dark Camp wouldn't fight each other for the sake of mere vanity.
Such strong figures do not casually take action; when they do, they often strike their foes to the death!
Satan's fame is largely due to the Demon Realm's strong inclination toward external conquest; various clans of the Demon Realm are often at war outside, causing the Ten Thousand Worlds to fear them immensely.
