[Wasteland Republic + Hard Core Technology + Cthulhu]
Gray mist locks the city, and the old gods whisper. The heroine Lin Wan, who majored in science and engineering, traveled through time and became a low-level medical girl. She refused to cheat on the system and used local methods to make steel, synthesize ammonia, and penicillin to build a "city of steel" among the dead.
Gu Chen, the crazy soldier king whose life experience is a mystery, turned into a sharp blade and cut a bloody path for her.
When others pray to God and worship Buddha, she uses a scalpel to dissect monsters and uses fluid mechanics to remove poisonous barriers. From slums to arsenals, from exploring ancient tombs to the national war of resistance, this is a passionate epic in which rationality crushes superstition and industry confronts gods.
"The whole city is charging, the target is the old god himself. Fire!"
