LZ will not be a primary school student who has never studied physical chemistry. It doesn't matter. You don't need to know so much, but you can master it faster after you learn it, because you came into contact earlier. When I was in junior high school, I read the magic forbidden book catalogue and the super electromagnetic gun, which involved a lot of physical and chemical things. I didn't understand it then. Now that I am in high school, I feel much more interesting at once, and I feel different when I go back and watch it again.
But it's all personal opinions. If you think it's ok, please adopt it ~
