I transmigrate to another world and build a technology base from the start, awakening a War System!
Wipe out pollution, fight evil gods, crush magic with technology, and bring order to chaos!
But I don't know that I'm the only hope an otherworldly goddess has been waiting for through endless cycles of reincarnation!
It turns out I must make myself into a blade and enter the game in a spirit-blind body, vowing to break the shackles of time and space and save my beloved!
