Wait, who did the baby look like?

This is a spoiler from the novel:




The baby is An He's, the body that Feng Ming is using.
So it's "Feng Mings" biological child but before he was transferred to XiLei. So the child looks a lot like Feng Ming.
Before Feng Ming appeared, both Rong Tian and An He had different partners, An He liked both genders so ended up having a child with a maid. For anyone that is curious ╮(￣▽￣)╭
