Tang Zhan accidentally obtained the 'War Lord System' in the apocalyptic war, but he just wanted to lie back and enjoy life. He draws cards every day to redeem life skills, grows vegetables and fish, and leads a healing life. However, his laziness made him the strongest 'Army King' in the world - because his soldiers are all AI legions that fight automatically. While other lords were fighting for resources, he drank and watched the legion automatically push the enemy. After being betrayed by his brother, the system sent a free war legion. Tang Zhan just wanted to be a salted fish, but the system gave him the strongest combat power; he didn't want to fight, and the enemy had to come to his door. A series of "forced and helpless" battles began, and he gradually realized that the real strong man can maintain a calm smile in desperate situations.
