The End of the World Begins, Start with an Elite Class

When the apocalypse breaks out, retired college student Gu Chengyuan accidentally activates the war system, obtains an elite infantry squad and armored vehicles, and uses Yezhou University as a base to gather survivors. He wiped out zombies to obtain crystal cores to expand his troops, and fought against mutants, "Revival Society", "Purification Society" and other forces, and gradually revealed the truth that the end of the world is the "Purification Agreement" of higher civilization. In order to save his relatives and find a chance to survive, Gu Chengyuan formed an expeditionary force and traveled through dangerous places such as radiation zones and deep-sea ruins to collect three keys and face the pursuit of the "Master" and the "Monitor".
