Logically speaking, it was already very strange for the Ji family's wife, Jiang He, to give birth in that small provincial capital. What was even stranger was that after the child was swapped, the Ji family did not suspect anything.
After all, the difference between the Gu couple and the Ji family was too great. It was already very difficult to enter the Ji family's delivery room, but they could actually switch the two infants successfully.
The illegitimate child was only half a month younger than Gu Xiao. It was hard not to suspect that Ji Gao had deliberately set this up when these clues were put together.
If Jiang He and that mistress had both given birth to girls, they would have given birth at about the same time.
