I don't mind it because she's not the one doing it. Shizuko is like the mc or player of a civ builder, and this is a scenario where she has access to a tech tree. She knows that X Engram exist somewhere down the line, but, she doesn't know how to make herself. So she sets her researchers on unlocking it.
Now, you might say that there are other mangas with the similar gist of Urban Developement that have a side character that does the same. But, here and for me, it actually takes real time for her to accomplish these things. From days, to weeks, months, and even years...
That's this manga's strongest point is something very few can or are willing to replicate: The Grind.
You don't just have magic maniacs that immediately Henry Ford Assembly Line whatever is put in front of them, it takes a while for her to work up an infrastructure that allows industrialization. We started off with chapters that were dedicated to her using modern agriculture to feed her first village and provide tribute to Oda. And that took months to a year to show the fruit. Basically an entire arc on simple farming techniques.
Even this simple microscope is the result of her asking a blacksmith to make her basic crossbow from those chapters. As it is also from her getting them to make glass many chapters later. As well as the telescope that she present Nobunaga with. It didn't come out of nowhere, it's been grinding in the back ground almost the entire manga when you break down the tech tree that lead to it.
It's just that now, she has had so many other bases covered that her researchers can run full time. Every advancement in tiers basically increased the number of projects she could run simultaneously, which means the fruits that bare are more plentiful. And now everything is popping off because she has entire departments that run themselves without her.
And god I love it. The Grind is BEAUTIFUL.
