Naturally, Gu Ruyun didn't know anything about what happened on Xu Rantong's side. She even left Xu Rantong behind.

Even if he went to Xu Rantong's birthday party, Gu Ruyun couldn't find out why the original owner's body suddenly palpitated, but as long as the heart didn't hurt, Xu Rantong would no longer come to her to make trouble for her, and Gu Ruyun also Don't care about that.

She still has a lot of things to do now, and she really doesn't have time to pay attention to Xu Rantong, whether it is to cultivate to improve her physical fitness, improve the strength of this body, or refine genetic medicine to improve the genetic level of the body, or Treating Xiao Zhan, helping Xiao Zhan stand up again, and even the fact that the original owner needs to take an exam to get a doctor's qualification certificate is much more important than Xu Rantong.

Of course, there is a more important thing now, and that is Doudou in the orphanage.

Although she knew that Doudou was due to her congenital heart, her heart couldn't handle the operation of Doudou's body, which led to her failure and death, but Gu Ruyun still wanted to see if she could use the knowledge she had learned in her previous life to cure her. this poor child.

According to the original owner's memory, Doudou is only about six or seven years old this year, and he is a very cute little boy.

When he was still a baby, he was abandoned at the gate of the orphanage. Doudou was in poor health, so even boys, no one was willing to adopt Doudou.

Dean Gu took Doudou to see a doctor a long time ago, but unfortunately, no matter which doctor saw Doudou, they all shook their heads and told Dean Gu that with Doudou's body, I'm afraid I can't live past ten years, unless I'm lucky. There is a suitable heart to supply Doudou in society, otherwise... Doudou's life is probably only so long.

But even with the right heart, with the living standard of the orphanage, there is really no way to spend the money for Doudou's treatment.

The money for a heart replacement surgery is too expensive, not to mention that after a heart replacement, you have to take those expensive medicines for conditioning every day, which the orphanage can't get.

Every year there are children who die in the orphanage, and most of these children are children under the age of ten...

There are even many who died in the orphanage in less than a month.

Like Doudou who grows to over six years old, until the heart is really unable to bear, it is very few. Doudou has lived in the orphanage for so long, whether it is the other children in the orphanage or Dean Gu and others Dou likes them very much, and the relationship between the original owner and Doudou is the best in the entire orphanage.

This is not only because Doudou has a cheerful personality and is a good boy, but also because Doudou and Xu Rantong suffer from the same congenital heart disease.

There are many types of congenital heart disease, including Ebstein malformation, atrial septal defect, tetralogy of Fallot, etc. Among these more than a dozen diseases, the most serious one is tetralogy of Fallot!

Doudou and Xu Rantong are both patients with tetralogy of Fallot.

However, Xu Rantong's condition is slightly lighter than Doudou's. In addition, the Xu family has worked hard to help with treatment and maintenance over the years, which has allowed Xu Rantong to grow up to this age, even compared to when Xu Rantong was eight years old. When I leave, I look much healthier.

It should be noted that among the more severe patients with tetralogy of Fallot, 25% to 35% will die within one year of age, 50% will die within three years of age, and 70% to 75% will die within ten years. within the age of 90% of people will die.
