Overview:

With the arrival of mysterious super-era technology, Gene Lock promotes unprecedented strengthening of human body functions such as speed, power and senses. Those who successfully open the genetic lock are able to become "agents", with the best among the agents being the "gun gods". Around the new armament of gene lock, various forces fiercely struggled to establish academies to cultivate agents. With the breakthrough and application of experiments, and the coercion from the mysterious race, the world has gradually fallen into the quagmire of war. After the war, the mysterious race disappeared, and the agents and spears became unproven urban legends. The only remaining two special agent organizations, "Deep Sea" and "Dead Snake", moved their bases to the seabed and underground, respectively, without disturbing each other. However, under a peaceful scene, it is actually in crisis. The dark tide is still tumbling, and the great wheel of history has never stopped spinning.
