Honkai Impact: Star Dome Railway Is Just a Show, Isn't It?

Looking for a New Book of COS Templates for Playing, Preferably from Star Iron, Genshin Impact and Honken 3

I want to read a book similar to "Heng Tie, but the plug-in is to transform into a Honkai Valkyrie". There are enough weird stories about national luck and rules. It's better to be a realistic cosplayer. I hope some author can write a new one, or add more systems to directly transform. Of course, it can be changed into many kinds.
