The Last Action Is His Chapter 230

A month later, in late October of the 21st year of Chongzhen, the first steam engine on earth that was purely handmade and not only expensive but also had a lower heat conversion efficiency than later generations was finally built.

If we calculate the cost, no one can afford the price of this steam engine. Even if the imperial court wants to build it, if there is no time traveler who clearly knows how great the prospects of the steam engine are, they will probably give up.

Now that the first steam engine has been built, the experience of building a steam engine is available, and the cost of the next steam engine can be reduced.

The steam engines built earlier were all used for military purposes, as the power source for the Arms Bureau to manufacture weapons. The production of cannons and flintlock rifles was much faster.

Every flintlock rifle has rifling, but what is the best rifling? A special group at the Armory Bureau is still experimenting to see what rifling shape is the best.
