Billions of years ago, the Seven Realms flourished, and powerful beings could cross between realms with ease. But excessive prosperity brought a crisis: the entropy of the laws.
Cultivators in every realm kept creating new laws and divine abilities, overburdening the worlds’ origins. At last, the Seven Realms began to “slip” toward primordial chaos, on the verge of merging back into a single whole.
At that moment, seven supreme powerhouses discovered the secret of the “Ruin.” They sacrificed themselves to create the Ruin Sea beneath the Seven Realms, a vast buffer zone. The Ruin Sea slowly devours the excess laws spilling out of each realm, preserving the balance.
As the price, the seven supreme powerhouses became pillars of the realms, guarding the Ruin Sea for all eternity. They were revered as the “First Generation Ruin Emperors.”
