Mechanical Core Era

[Mechanical ascension + slow pace + no heroine + not invincible] In 4655, the singularity arrived, and civilization leapt forward in a carnival with unlimited energy given by the singularity. However, the accompanying disaster has already come, and the former Blue Star has become a wasteland. Humanity relies on mechanical transformation and spiritual evolution to raise 25 sky cities and build the last isolated island of civilization at an altitude of 256 meters. However, there is an undercurrent beneath the prosperity. The countdown to energy exhaustion has begun. Deep in the mechanical pillars supporting the sky, the cruel truth about "raising" and "harvesting" is buried. When technology becomes a curse and survival becomes a transaction, this is an apocalyptic epic about steel, blood and humanity struggling to survive on the edge of destruction.
