The Steam Reduction Faction, a civilian scientific organization established at the beginning of this century, is characterized mainly by its dedication to steam retro activities.
The so-called steam retro activities involve using steam age technology to produce modern technological products. They have manufactured steam cars, steam planes, steam computers, and steam radios...
Steam cars, Li Banfeng has seen; steam planes, seen in some historical records; what is steam computer?
Dumpling introduced the principle of the differential machine to Li Banfeng; this mechanical computer, which was never successfully built in history, was successfully manufactured by the Steam Reduction Faction.
This reminded Li Banfeng of the retro craze popular in his university days, where many faculty and students in the mechanical department were keen on restoring ancient mechanical devices, the most typical being the renowned wooden ox and flowing horse.
