Three years ago, Tianyun No. 1 Crashed into the earth with an alien mechanical matrix. Massive nanomechanical insects swept the world, eating metal and transforming living things. Human civilization collapsed overnight. Mechanical beasts and mechanical apostles ran rampant, and the survivors lingered in the wasteland. Lin Ye, a former auto mechanic, was separated from his 16-year-old sister Lin Xi due to a disaster. He only had a brass pocket watch engraved with the word "Xi" to remember him. He traveled all over the southwest wasteland just to find any trace of his sister.
On the way, Lin Ye formed a partnership with the rough man Lao Chen and became the backbone of the refugee camp in the barren mountains. However, due to the sudden increase in the concentration of nanoworms, he was attacked by a pack of iron-spine wolves. In order to protect the refugees, Lin Ye cut off the enemy and set out with others to escape to Qinggang City. Unexpectedly, he was targeted by the vicious Black Rock Hunting Group, who coveted his mechanical repair skills and pursued him all the way to Qinggang City.
This mysterious abandoned military-industrial city is a rare safe zone in the wasteland, but it also hides unknown dangers. Lin Ye relied on his mechanical skills to escape death several times and led everyone into the center of Qinggang City. At this moment, the pocket watch on his chest suddenly moved, echoing the signal tower in the center of the city. The traces of his sister and the truth about the mechanical catastrophe were quietly emerging.
