My Battlefield Simulator

In the beginning of the apocalypse, the protagonist has to become a soldier in order to survive. The disparity between the enemy and ourselves is so great that the protagonist thinks he will definitely die. Just then the battlefield simulator was activated. You can know the battle situation in advance and you don't have to die in the simulator. The protagonist relied on the simulator to win one battle after another. The myth of a sniper rifle, a real version of chicken fighting, just started with the simulator. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
