Master of Mecha Piloting in the Ultraman World

Following the Dimension Administrator, another traveler from the Ultraman world has set out on his journey. His path is far more difficult than his predecessor's. He has no overwhelmingly powerful System, only a weak little thing that can provide blueprints, metal, and energy. In the vast Ultraman world, he pilots giant mechs with his frail body and battles one enemy after another.

The young Su Lang arrives in the Ultraman world with the Mech Pilot System, which has drained several years of his life force. Starting out in the Max world with just one Legionoid, he fights his way up. With two items gifted by the Dimension Administrator before his transmigration and a relatively weak System, he rises from the bottom of the Ultraman world to become an indelible beacon of hope.

(No heroine) I'm not good at writing synopses. Please read the story itself...
