Hidden Dragon on Campus

He was the top mercenary abroad, codenamed "Ghost Wolf." He roamed the battlefield for fourteen years without ever failing. Until his last mission, when his teammates betrayed him and he was surrounded. When he opened his eyes again, he was sitting in a high school senior classroom, faced with a mountain of exam papers, and outside the window was the chirping of cicadas in August. An eighteen-year-old body with the soul of a war king. All skills—combat, firearms, tactics, intelligence, six languages—were retained. He knew the direction of this world, including the global crisis three years later that would destroy all order. This time, he didn't need to listen to anyone. Starting from this classroom, he would stand at the top of the world again.
