The World of Science Climbs the Magic Technology Tree

Particularly important note: The most important tags of this novel are: sister control and daily life! Then comes farming and other things. The original title of the book was expressive, but, well, I wasn't allowed to use it, so I just used such a generic, neutral and boring title. "I still need to learn math!" "The script for this game is not finished yet! Brother, you can't delay the draft!" "I still want to study nuclear fusion!" "The game needs additional production tomorrow, brother, help me quickly!" "My unified field theory hasn't been completed yet!" "No matter, brother, come here quickly!" At this time, an older brother wanted to climb the technological tree to save mankind (what he thought he was), but he was always dragged by his younger sister for various reasons to produce some happy stories with gentleman content.
