Veteran of the Apocalypse

Story:

He was just an ordinary guy running a small restaurant. But behind that quiet life… he was actually a legendary veteran who spent thousands of hours in a hardcore zombie-survival VR game. Then one day, the world he knew turned upside down. The game he mastered…dying and respawning endlessly…suddenly became real. A zombie apocalypse breaks out without warning. At that moment, he awakens a strange power: the ability to open dimensional gates. Now he moves between this world and another, preparing for the coming collapse. Soon, familiar faces from his gaming past begin to appear… the endlessly respawning Bunny Princess, Duck-Butt Quack-Quack who commands monsters, and other unbelievable players start “logging in” to reality. The world is falling apart. Humanity blurs with pure survival instinct. But he stands firm: “This isn’t a game… but I know this battlefield.”
