With skills that can be upgraded infinitely, if I'm invincible, who is?

When the mysterious game known as "Immortality" descends upon the world, humanity is thrust into a desperate struggle for survival where relentless leveling and strength are the only paths to tomorrow. At the outset, Su Yu awakens a divine-grade talent: Infinite Growth. From that moment on, the rules of the game no longer apply to him. While others fight tooth and nail for every inch of progress, Su Yu endlessly learns and upgrades every skill in his arsenal to unimaginable heights. Level 9,999 Soul-Severing Arrow. Level 9,999 Powerful Arrow. Level 9,999 Glorious Halo. His power knows no ceiling. Years later, when Su Yu finally stands before the ultimate mastermind orchestrating the "Immortality" game, he merely grins and says, "Don't be afraid, I'll only shoot one arrow." In an instant, the architect of worlds vanishes into nothingness, erased completely from the eternal river of time. With skills that grow without limit, when true invincibility is achieved, who is left to stand in his way?
