it would have been a better intro if things were casually introduced through mcs pov, mad eus experience the changes through his eyes, and make us learn about things through vague yet contextual evidence of what he finds and sees. that would kill info dumps but would make the world more memorable and easier and interesting to read, although it would take up more chapters, it'd be overall better and make you stand out and be more unique among webnovel
hey just wanna say you should start with a proper intoduction, I am not saying this novel is bad, it honestly has a lot of potential and so far you have done a great job writing it, it just have few thing missing. 1) you didn't mention the name of thes academy they are in. 2) you didn't mention the city, country or world they are residing in as you mentioned that earth started expanding it's territory which obviously mean to other world .
