Three years ago, Qin Mu was betrayed by his teammates, and his entire squad was wiped out. He survived, but became an unknown veteran, making ends meet as a residential compound security guard. When Xiao Tieshan tried to force the compound's residents out, they knelt and begged Qin Mu to step in. Qin Mu didn't want to get involved, but a message suddenly popped up on his phone: “War God Card System bound. First mission: Defeat Xiao Tieshan. Reward: Han Xin Tactics Card. Mission failure: Erasure.” He laughed, his eyes reddening. It was time to settle the debt from three years ago.
