"You said that Yu'er gave birth to a girl? That girl is now your wife? How did you find out that she's Yu'er's child? Also, how did you get your hands on Nangong Yun's blood?" Nangong Qin went straight to the point.

As you know, sir, the country is advocating for blood banks to be built, so we retained a small blood sample of every patient who comes to our hospital."
