National Fate Collapses, and I Become an Iron Curtain That Shocks the World

In the High Martial Era, the National Destiny Arena descends upon the real world! The victors enjoy flourishing martial fortunes, while the defeated see their destiny collapse and their cities overrun by alien beasts! The Dragon Kingdom is targeted and suffers defeat after defeat. Its destiny is nearly exhausted, and the entire nation sinks into its darkest hour! For the third battle to the death, Su Ming, who has no martial cultivation whatsoever, is chosen by mistake. The Western nations mock him wildly and celebrate in advance, while hundreds of millions of Dragon Kingdom citizens despair, believing their country's destruction is imminent. But in the arena, Su Ming awakens the Myriad Worlds Conceptual Transformation System! Facing the enemy nation's lofty martial prodigies, Su Ming sneers. Before billions of people watching the global livestream, he unlocks the ultimate move from the start: the Iron Curtain Device! Boom! An impenetrable Iron Curtain stretches across heaven and earth! It not only ignores every martial attack, but also unleashes an energy backlash that instantly wipes out the destiny of the enemy nation! At that moment, the world is stunned! The internet erupts! The enemy nation is horrified and despairing! And this is only the beginning. [Mechanical Titan], [Planet-Cracking Orbital Cannon], [Two-Dimensional Foil]... As Su Ming transforms into one terrifying, concept-level form after another, each capable of striking from a higher dimension, all the races of the myriad heavens tremble! “You were supposed to fight in a High Martial arena, so why the hell are you using higher-dimensional attacks?!”
