The Earth in 2247 AD is no longer the livable planet it used to be - a "particle storm catastrophe" swept across the world a hundred years ago, and the fires of civilization in the old era were almost burned out. The once prosperous cities were reduced to ruins. After the continental plates were restructured, large areas of land were swallowed up by deserts. The remaining humans gathered in a few "safety domes" and relied on remaining technology to survive. In this context, genetically enhanced organisms have become an important driver of human survival. Iron Claw is the third generation of genetically enhanced search and rescue dogs bred by the Dome Academy of Sciences. Its parents were once meritorious dogs in ruin search and rescue, and it has been implanted with enhanced gene sequences since birth. The alloy claw guard on its right front paw is customized equipment by the Academy of Sciences, specifically used to deal with sharp obstacles and energy impacts in ruins. The bond between it and its owner Lin Mo was established in the missions of searching for ruins and missing people. Lin Mo is a member of the scientific expedition team sent by the dome. This time he went deep into the rust belt to explore the remaining data of the particle accelerator experimental base of the old era and try to decipher part of the truth about the "catastrophe". Iron Claw is his most trusted partner and comrade-in-arms.
