In the last ten years, alien beasts are rampant in the wasteland, and humans are huddled in the remaining settlements and lingering. {Lu Yuan} accidentally awakened the [God-level Beast Master] professional system during a siege by alien beasts. He wanted to use the system to protect the village and rebuild his home, but unexpectedly he was regarded as a thorn in the side by the cunning village chief, who planned every step. To make matters worse, his nemesis, the cold and powerful Su Qingyuan, was actually bound to a system-forced team task with him. The two went from tit-for-tat and trying to undermine each other, to being forced to fight side by side and rely on each other for life and death. Just when {Lu Yuan} thought his ideal was within reach, he discovered a shocking conspiracy of the village chief colluding with alien beasts and hiding fatal bugs in the system. The village he relied on for survival was reduced to purgatory, and the ideal he had pursued throughout his life was shattered. In a desperate situation, {Lu Yuan} and Su Qingyuan made a contract with the most powerful alien beast, ripped out system bugs with their own hands, kicked the conspiratorial village chief, and fought their way out of the wasteland in the name of a beast master!
