Wonder why Yulan only showed concern about her in this timeline. MC did say that she didn't notice him the first time, did he not try again to reach out to her in the first timeline?
Yeah this is fun to read. The MC is definitely a mary sue, but not an annoying one IMO. I think the plot matched well with his power level too. He's obviously too powerful to fight the other students, so the next appropriate opponent would be the demons.
