After the zombie crisis broke out, Ling Yu died trying to save people, and after death he was somehow reborn as a nuclear power plant in his own city.

Facing nearly 300 zombies across the entire plant and a reactor core on the verge of meltdown, with nothing on hand but 6 cleaning robots and one survivor girl holding a crowbar, Ling Yu said, I'm just a harmless little nuclear power plant, what evil could I possibly be planning?

【Ding! Survivor containment quota completed, reward: 1 needle based molten salt reactor!】

【Ding! Zombie cleanup quota completed, reward: 1 controllable nuclear fusion stellarator!】

【Ding! Civilization development level meets standard, reward: antimatter engine technology!】

Starting from an ordinary pressurized water reactor, all the way to a hyperreal engine capable of rewriting reality, from being trapped in one corner to sailing the sea of stars, Ling Yu pushes civilization to its absolute limit step by step. This time, he's going to show the entire universe what a true mechanical apocalypse really looks like.
