Ryan Lincoln was reborn, reborn in the year 4161 AD, two thousand years in the future.

　　In this era of highly advanced technology, the pinnacle of human biotechnology has collided and merged with the civilization of Celestial Star, giving rise to a path of human evolution—‘Symbiotic Martial Arts’—that allows people to achieve immortality and transcend the universe.

　　The entire society reveres the strong, and people take pride in practicing Symbiotic Martial Arts. There is even a group of ‘Variant Walkers’ who stand at the top of the pyramid, looking down upon the world.

　　At first, Ryan Lincoln couldn’t figure out the meaning of his rebirth. Out of a sense of responsibility, he simply tried his best to adapt to this era.

　　Until one day, the ‘Battle Spirit Ring’ that accompanied Ryan Lincoln captured its first battle spirit.

　　Ryan Lincoln could let the battle spirit possess him in combat, and could also copy all the martial skills and abilities mastered by the battle spirit. The battle spirits he captured grew ever stronger—

　　Ryan Lincoln began to realize that this era belonged to him.

　　A future ‘Ultra-Abyss’ who would one day rule the world with a single hand began his rapid rise at the Ninth Base of Celestial Star.
