Ok I dont get it ?
Why cant he give him the blood?

Direct blood relatives cannot be transfused directly, otherwise, they will be rejected immediately, and severely will cause death. Luo Xiaomao still knows this common sense, but Qu Cheng is Wowo's father. If he does not stop him now, Wowo will really be dead.
You can just read this thread here for more detailed answers: http://www.mangago.zone/home/mangatopic/9977865/

Their blood would not be very compatible, it would literally kill Wowo, how can that be described as compatible? It's not about the secret at all, would you think LXM would value that over Wowo's life? It's stupid to think that people believe that parents are the best donors for their children's blood. Please do some research and don't tell me that their blood is "VERY compatible". It's a real thing in real life, one that could determine life or death.

Lmaoo its funny how you get defensive real east when you dont know about something 100% just searched it up and no its not for sure that they cannot give blood. The compatibility varies from blood to blood. When they test the blood they will see if it’s compatible or not so theres no need to be scared of wowo dying. The doctors arent dumb my guy

But it's still a total emergency, it's much better to just get someone who is not related to Wowo because they would just be wasting time if they have to get QC's blood tested, possibly being too late for Wowo. And this is not something that I only searched about, I'm quite interested in things like this and would often ask my mom(nurse) for more information in the things I search up online. And besides, the novel itself that implied this line. "Direct blood relatives cannot be transfused directly, otherwise, they will be rejected immediately, and severely will cause death. Luo Xiaomao still knows this common sense, but Qu Cheng is Wowo's father. If he does not stop him now, Wowo will really be dead."
