Three years ago, Chen Mo, the Dragon Group S-class "Dawn", was forced to "die" because his mission was ruined. After losing his memory, he became a loser despised by everyone on the street. Three years later, the top-secret archives of the Dragon Group were invaded, and a document named "Project Abyss" exploded across the sky, drawing Chen Mo into the whirlpool. Intelligence section chief Su Wanqing discovers his connection with "Breaking Dawn", hot-blooded newcomer Jiang Ruoli's impulsive pursuit, logistics Zhao Tiejun's mecha blueprints hidden, and underground intelligence dealer Meng Po's memory bait - everyone is forcing him to regain his strength. When Han Yuan, the deputy leader in the shadows, showed his fangs, Chen Mo had to use his fists to reveal the truth: he was never a loser, but the Dragon Team's last trump card.
