Doomsday Age: Machine Heart and the Eternal Throne

In the near future of 2056, in an era of global catastrophe caused by a meteorite impact, the world is at the critical point of civilization collapse and technological explosion. The story begins at Donghai University of Science and Technology, and gradually expands to a shelter full of quantum shields and a radiation zone full of mutant creatures.

Human society has rebuilt on the ruins a new technological system that relies on energy crystal nuclei to operate.
