- Description from Novelupdates

Lin Rui was reborn, reborn in the year 4161, two thousand years later. In this era of highly advanced technology, where the peak of human biotechnology had collided and fused with the culture of Tianji Star, a new path for human evolution was born—’Zhi Zhuang Wudao’, capable of granting eternal life and transcendence beyond the universe. The entire society esteemed the strong, and it was considered an honor to practice Zhi Zhuang Wudao. There was even a group of ’Variant Walkers’ who stood at the pinnacle of the social pyramid, looming over the world with arrogance. At first, Lin Rui couldn’t fathom the meaning of his rebirth. He merely adapted to this era out of a sense of responsibility. It wasn’t until one day that the ’Battle Spirit Ring’, which had come into existence alongside Lin Rui, captured its first Battle Spirit. Lin Rui could let the Battle Spirit possess him for combat, and could also copy all the martial skills and abilities mastered by the Battle Spirit. The Battle Spirits he captured grew increasingly powerful— Lin Rui began to realize this era was his to own. A ’Super Abyssal’, who would overshadow the future, began his rapid development journey at the Tianji Star’s ninth base.
