(ABO + GB + superpowers + level-up progression + secret identities + feel-good power fantasy + academy in the early stages, battlefield later + blended worldbuilding)
After transmigrating, Shen Yunqi becomes a rookie Alpha in a BO world, fretting over how to get by at the academy. Then she unexpectedly awakens the superpower "Multidimensional Split Body." Wow! Now things are getting interesting!
The main body is dozing off in class? No problem! Clone A is lifting weights at the gym, clone B is devouring books in the library, and clone C has even sneaked off on a date! She can master in a minute what takes others a year! But wait, how can she use such an awesome ability just to get through exams? Why not go all out?
Much later, the whole interstellar world realizes: Wait, why is the famously cold-blooded inspector general Shen Yunqi? Huh, why is the hot-tempered little firecracker who makes people obey with a mortar also Shen Yunqi? Ah, why is the Imperial fleet commander still Shen Yunqi...? What kind of interstellar Miss Ice is this???
