It’s not an omegaverse. So Ci Nian is male but has a womb; thus making him a hermaphrodite. Therefore, when Cheng and Ci Nian did the nasty when they were in jail, Ci Nian got pregnant. Hope that helps :)
Maybe Ci nia was born with a special body which is closely like the female body and can be pregnant?
I think Ci nian was both with both male and female sex organs. I think that’s why he was able to give birth to Wo wo
I think ci nian is born with a functioning uterus maybe birth defect or sth but they didn't say its an omegaverse
theres sometimes cases of man having a bed for a baby but theres only small chances but the reason ci nian got preggy bcz he has one , hope it helps (=・ω・=)
the correct term is intersex.
Ahhhh now i understandd
Is this stories about omegaverse? Cause i don't understand how can cinian and qu cheng are wowo parents if this is not omegaverse story
