With the advent of advanced super-era technology came the Gene Lock, a revolutionary technique that greatly enhances a person's speed, power, and senses. Those who successfully unlock their genetic potential are known as "agents," with the most skilled among them earning the title of "gun gods." Factions fought fiercely to establish academies for training these agents and controlling gene locks through experimentation and the influence of extraterrestrial beings. This led to a global conflict until the mysterious race disappeared, leaving behind agents and their abilities. Today, the only remnants of these past struggles are the two surviving organizations: "Deep Sea" and "Dead Snake." Both agencies have relocated to the seabed and underground and have agreed to a truce. However, conflict still lurks beneath the surface of tranquility. Our story begins when Lin Xiaoshuai, a master martial artist, stumbles upon the Deep Sea Special Academy. He and his comrades will embark on a journey to unlock their genetic locks, master combat, and firearms, and become agents, possibly even gun gods. The anime is divided into four chapters: The Secret Service Academy, The Special Agent World, The Secret History of Blood Race, and Deep Sea Falling. With 48 episodes spanning four seasons, viewers can expect a thrilling journey in a world of power and mystery.
