Just FYI, this work does not in any way delve into sensitive ideology like Socialism or the like, just plain pure fantasy novel. This is an interesting piece, if you like Release that witch then this is just as good. The main focus is kingdom building and science advancement, but is way more interesting due to physic being off (so no Isekai cheat nuke for you). The world building is deep with many background lore and legend. If you are impatient check out the manhua of same name.
