Maybe their religion is Buddhism? Buddhists believe in the concept of nirvana and/or reincarnation.
the original stepbrother died and someone else reincarnated into his body, which is why he is so evil, because he is a different person than the bodys original owner
You know those famous transmigration genre? That's what happened. There is another person's soul inside the brother's body.
Oh. So apart from being mpreg this also that that theme?
Yeah, usually it's the main character but this time it's the brother so it's really not the main genre of the manhua.
Reincarnated what the hell is that mean? Also can't wait to see when Cheng Ge found out that wowo is his child
