If you have ever imagined that the mechas of "Pacific Rim", the Zerg of "StarCraft", and the nameless things of "Cthulhu Mythos" collide in the same universe - this story will give you the answer.
Anti-routine career setting: Others fly mechas to save the world, while I fly mechas to pick up trash and support my family.
Cthulhu-style mecha: "bio-metal", "emotional swallowing" and "driving is symbiosis" are horrifying to think about
Multiple suspense progressions: Why did the mechas awaken → The truth about the iron-eating insect civilization → The reconstruction of the relationship between humans and mecha civilizations
Hard-core technical details: From modification of engineering pliers to quantum weapons, maintenance knowledge becomes the most powerful plug-in
Discussion of ethical dilemmas: When tools have souls, are we the controllers, or are we captive hosts?
