Steam Age: I Rub My Mecha in the Doomsday World

Traveling back to 1892, what Lin Yuan saw was not the prosperity of the Victorian era, but a rusty hell. A strange nanovirus is raging around the world. The dead will rise again, sprouting exhaust pipes and driveshafts; There is no longer muscle under the beast's hide, but a turning ratchet; Even the plants began to reek of motor oil. Facing this "mechanical plague" that transcends the times, the old world, which has already distorted its technological tree, is helpless and can only wait for its demise. Fortunately, Lin Yuan brought engineering wisdom from another world. Even if there is only the simplest lathe, the roughest black powder, the most primitive rivets... Just give him a blueprint and he can create a sharp blade that tears through the darkness. This is a story about a military industry that builds the last beacon of mankind in a steam wasteland.
