The Modern Era's Strongest Soldier Conquers the Otherworld Dungeon

Hasumi Ryuuji, known as the modern era's strongest soldier, is a man capable of making numerous difficult strategies s쳮d. During a mission, he is suddenly transported into the depths of a dungeon in another world. A heavenly voice echoes in his mind: "Welcome, hero from another world." He comes upon adventurers under attack by monsters. Using superior physical abilities, discernment, and hand-to-hand combat skill, he easily dispatches the monsters. In this world where adventurers are weaker than monsters, Hasumi—able to subdue a target with only a knife—is regarded as a hero for his outstanding abilities. Hasumi decides to cooperate with the adventurers he rescued, but they are attacked by a dragon and fall into a critical situation. He leads his panicked comrades, coordinates them, and creates an opening for attack. Then, using a "weapon summoning" item, he summons modern firearms and kills the dragon in a single shot by accurately targeting its weak spot. Before his tempered body and intellect, even a mythical-grade dungeon poses no threat. Asked "Who the heck are you?" he answers, "I'm just a soldier." The curtain rises on the story of an ex-special forces soldier turned adventurer challenging another world.
