"Average" high school girl at it again, now with microscopes 🙄
Most actual average high schoolers (that's not in engineering and/or a nerd) would remember ZERO of the blueprints for these inventions.
Sorry if I'm complaining (again) this late, but this one thing takes me out of the story since it's so easy to fix: just create other characters that could've made these inventions. Even super genius Senku needed other talented people to create most of this stuff that he thinks up/remembers.
Technically, she's already doing this and has these people in her employ by now this late in the story, but the crossbow thing back when she only still has a village still bothers me. Some random village blacksmith would not know how to make a crossbow.
