I, the Strongest Soldier, Became so Poor After I Retired

I, codenamed King of Hell, am the former strongest military king of 'Dragon Tooth'! But after retiring, the hero has no place to play, his bank card balance is only two digits, and he can hardly afford to eat instant noodles! When I thought I was going to be this useless for the rest of my life, my neighbor's aunt knelt down in front of me, crying and begging me to save her daughter who had been deceived into going to northern Myanmar. Remuneration, three hundred thousand! The moment I touch the gun, the whole world will tremble for me! They said I had crossed the line, that I was crazy and a devil. But they don't know that I formed 'Nightmare' just to give my brothers a full meal! By the way, send the scum of this world to hell one by one with your own hands!
