My Childhood Friend, the Emperor, Is Not the Holy Roman Empire’s Mother

Reminds me of this old comic

I really should give you a good shock

The writing is good, and there are some clever ideas from the author, such as Hans and Henry, the pair of miserable mandarin ducks.

The quality is surprisingly good, but why is it a light novel? Shouldn't this be a historical novel?

The main theme of the book

The reason Watt didn't develop the double-acting steam engine until 1781 wasn't because he was brilliant, but rather due to the issue of machining precision. It wasn't until John Wilkinson invented the boring machine in 1775 that cylinders with smaller errors could be manufactured, solving the leakage problem.

It feels a bit far-fetched. They haven't even won many battles, and they're already starting tax reforms. They don't even have a directly controlled military force yet, and they're already doing this? I really don't understand it.

Is a steam locomotive actually a car? I thought the protagonist was researching trains, but it turns out he's making steam cars. I think we should first study the popularization of trains? For a territory as vast as the Habsburg Empire, wouldn't trains be more valuable?

In the past, I couldn't connect the words "loli" and "mother," and even considered those who combined them to be heretics. But when I saw Theresa, with her loli-like figure, radiating maternal glow, I understood—long live loli mothers! Long live loli mothers! Loli mothers are the best! I will swear to protect all loli mothers in the galaxy!

First, let's assume that, as before, Maria's father died when she was 23 years old, and then the story is told that Maria was 16 years old when the father died. The biggest problem is the lack of funds, and a princess at 16 cannot directly enact national tax laws. A better option is to first monetize the mercury mines.
