Earth's Strongest Couple in the Immortal World

Heritages: A set of abilities humans awakened. They could either be a set of many abilities or a single ability. The people who gained more than one ability at the time of Awakening their Heritage are called Royalty. The Royalty could absurdly sense what the normal Heritage Awakened people's abilities are at a glance. That power is known as the Eye of Royalty.

Ranks of Heritage Awakened on Earth:

D→C→B→A→S and there is nothing more, end of potential. Throughout the ages, no one had went beyond it and it had been considered impossible.

Immortal Cultivation Ranks are in the next Auxiliary chapter, beware of spoilers.
