In 2140, the mecha war destroyed human civilization, predators were raging in the wasteland, and the guardians held on to the shimmering light. Mecha maintenance engineer {Lu Feng} suffered a blood feud because his family died tragically at the hands of predators. By chance, he awakened the dusty high-level autonomous consciousness mecha "The Redeemer" - once the vehicle of the leader of the Guardians. One person and one machine formed an alliance and declared war on the predators with the power of steel. On the way, Lu Feng gathered frustrated mecha apprentices and formed a guardian team. They upgraded the mecha with top maintenance technology and forged combat power with passionate training. They resisted raids, defended settlements, and carved a path of hope in the wasteland. In the end, Lu Feng worked side by side with the "Redeemer" to end the tyranny of the predators with the precision of the maintenance technician and the power of the mecha's thunder, bringing peace to the wasteland, and passing on the belief of the mecha master in the name of guardianship.
