There's a Rose in His Gun

Huang Huai is the top killer hidden in the world. The world only saw the cold muzzle of his gun, but little did they know that there was a rose hidden in his gun. Deeply trapped in a life of killing, he did not lose his original intention. Never kill indiscriminately, stick to your moral bottom line, and stick to your inner feelings. In one mission after another, he walked alone in the dark world, guarding goodwill in his own way, and keeping his own gentleness in his killing career.
