Demon Slayer: I Am the Star Pillar

[Demon Slayer World + No CP + Strong Female + Difficult to Calm Down + System + HE] Currently I plan to revise the previous chapters. The writing was terrible at the beginning, so the writing may be good and bad sometimes, so please forgive me. I saw that some people said it was like the book by Iizhu. I would like to mention here that even though it is Breath of the Stars, it is not plagiarized. You will know it after reading it. There is also the fact that the master is Flame Pillar. The original candidates were Yan, Lian, and Chong, but I personally feel that it is not suitable for Lian (after all, there is no cp, and I feel that writing about love is not very good). Another point is that Lian and Chong have too few breathing moves, and the names are very strange. I can't write them if I make them up, so Yan is the best choice. Once the protagonist uses Breath of Fire, he will create a new breathing method, Breath of Stars. When Hitomi woke up, she found that she could travel to the Demon Slayer world. Since she was a qualified Demon Slayer fan and had nothing to worry about, she chose to bind to the Demon Slayer system to save various troubled people. Discover the secrets of Star Pupils by the way. Everything was going smoothly, but the sudden appearance of a mysterious man broke the original plan. Why did you come here? Is this really the right thing to do? Who are they? What exactly is the purpose of the system? Note: The above will only appear in the later stage, and there will only be some foreshadowing in the early stage. HE! It's hard to get over the idea of ​​saving! (I am a novice writer, if I have any shortcomings, please give me some advice)
