Lin Fan, an ordinary college student, happens upon the transformation device of Ultraman Nexus at a flea market. During the final battle, he is forced to unleash his full power and transform into Ultraman Noa. Though he defeats his formidable foe, the immense energy tears through space and time, hurling him into a completely unfamiliar fantasy world.
In this world, where people cultivate vital energy and strength reigns supreme, Ultraman's power is utterly unique. Lin Fan discovers that transforming into an Ultraman here consumes not light energy but the world's vital energy, and every transformation triggers strange celestial phenomena.
From an initial host to a Giant of Light, Lin Fan must master the power system of the Ultramen anew in this harsh, survival-of-the-fittest world. Facing sect prodigies, ancient powerhouses, and demons from other realms, he must perfectly combine the power of light with the world's cultivation system and forge a path of his own.
As the world's dark forces gradually emerge, and ancient secrets reveal a mysterious connection to the history of the Land of Light, Lin Fan realizes that his transmigration was no accident. The arrival of Ultraman Noa in this world will uncover a shocking secret that could determine the fate of both worlds...
