Xu Xian has no money, and it is impossible for Jishitang opened in Zhenjiang to openly advertise that it is free. Some of the drugs in the system are sold at very high prices. Even if they only charge cost prices, they are still quite expensive.
Although Xu Xian became famous for saving the king, everyone still likes to look for old Chinese medicine doctors with white beards and hair. They are still suspicious of young people like Xu Xian who are hairless and just starting out.
Therefore, Jishitang's business is relatively light.
Occasionally someone comes over to see a doctor, but it's not a big problem and is handled easily.
Bai Suzhen and Xiaoqing are responsible for treating female patients. They have nothing to do, make a pot of tea and cook a few dishes of exquisite side dishes.
When Xu Xian had nothing to do, he talked to the two about the technology and food on earth.
Many of Bai Suzhen and Xiaoqing's dishes were slowly figured out based on Xu Xian's memories on earth. Even if some of them are slightly different from Xu Xian's memories, they still have a unique flavor.
Being bored, Xu Xian wanted to have a computer to surf the Internet.
Unable to purchase a computer from the system, the reason is that it has nothing to do with Jishi Living and insufficient permissions.
Xu Xian told the system that with computers, he could better study medical skills and bring modern civilization to the misty world, but he was ignored by the system.
On this day, a middle-aged man in Chinese clothes came to the store.
The middle-aged man is Qiao San, the third of the three Qiao brothers, and the landlord of the shop rented by Xu Xian.
"I'm sick. There must be something wrong with my brain."
Qiao San had an unconcealable tiredness on his face and said:
“I’ve been visiting traditional Chinese medicine doctors in Zhenjiang Prefecture these past few days, and they all said that I was too nervous and that I should just take a good rest.
But I know that everything is wrong, and someone is targeting our Qiao family.
No one believes me when I say it, but it’s true. "
Xu Xian really couldn't understand what Qiao San was talking about, so he poured a cup of tea, handed it to Qiao San, and said:
"First have a cup of tea to calm down, and then tell me the cause and effect."
Qiao San took the tea, raised his head and drank it in one gulp, then calmed down and slowly told his story.
Twenty years ago, Qiao San's wife died in childbirth, leaving only one son.
Qiao San did not renew her relationship, became a father and a mother at the same time, and finally raised the child.
One night half a month ago, Qiao San had a dream.
In the dream, Qiao San married another wife, lived a sweet time, and soon welcomed a second life.
Unexpectedly, Qiao San's second wife died in childbirth, leaving only a daughter.
After waking up, Qiao San thought it was Nan Ke Yimeng and didn't take it to heart.
When he woke up the next day, Qiao San discovered that he actually had an extra daughter, her name was Qiao Xiaodie.
The daughter in the dream appears in reality and has grown up.
What surprised Qiao San even more was that his family had become accustomed to her daughter's existence, as if his daughter had been living at home and growing up slowly.
Qiao San asked all the servants in the family, and they all said that Qiao San had married two wives in total, and had a son and a daughter.
Qiao San also asked his eldest brother Qiao Da and his second brother Qiao Er, and they both said that he had a son and a daughter.
However, Qiao San clearly remembered that he had been single for more than 20 years and had not married a second wife.
Qiao San only married a second wife in his dream, and he only had a daughter in his dream.
His wife is gone, and Qiao San doesn't hold her accountable. Instead, a daughter appears out of thin air. Qiao San really can't accept it.
In order to prove that he did not have a daughter, Qiao San asked people everywhere in Zhenjiang Prefecture. He wanted to be recognized and he wanted someone to prove that he did not have a daughter.
The three Qiao brothers are philanthropists and celebrities in Zhenjiang Prefecture. Everyone is familiar with their family affairs.
Everyone gave the same answer. Qiao San has a son and a daughter.
In order to prove that everyone was wrong, Qiao San decided to shed blood to identify her relatives. It turned out that Qiao Xiaodie who came out of the dream was really Qiao San's daughter.
Qiao San is also an awakened person. He also knows that whether he is an awakened person or a cultivator, his strength has a limit. Even if he is really good at mental power, it is impossible to tamper with the memory of everyone in Zhenjiang Mansion.
If there is no problem with others, it means that Qiao San himself has the problem.
Qiao San suspected that someone had tampered with his memory, making him mistakenly believe that he had not married a second wife in reality.
Qiao San went to see a doctor to prove that there was something wrong with his brain and that his memory had been tampered with.
The old Chinese doctors in Zhenjiang Prefecture didn't know how to treat this, so they just prescribed him some soothing medicine to ask him to take a rest and relax a little, so that he would be less nervous and naturally stop thinking wildly.
Qiao San also took the medicine and improved her work and rest schedule. She followed the doctor's instructions to go to bed early and get up early, but the doubts in her heart became more and more intense.
Qiao San wanted to find out the truth, and remembered that Xu Xian had cured rabies, and that he might have some real abilities, so he decided to come over and try his luck.
Xu Xian checked Qiao San and did some tests, but found no problems.
Qiao San is an awakened person, has relatively good physical fitness, and has not been found to have his memory tampered with.
Xu Xian decided to first determine whether Qiao Xiaodie was Qiao San's biological daughter before proceeding with the follow-up work, which required a paternity test.
Forensic identification of paternity has a long history.
After more than a thousand years of exploration, people have realized that both the bone test invented by the Song Dynasty and the blood test invented by the Ming Dynasty are unscientific, unreliable and untrustworthy.
The application of blood group theory and technology in paternity testing has opened up a new era of paternity testing and brought paternity testing into a scientific and credible stage.
As early as the Three Kingdoms era, there have been records of bone testing. Song Ci, a famous forensic scientist in the Song Dynasty, introduced this method in detail in "The Collection of Cleansing Wrongdoes".
According to the analysis of modern forensic theory, the bone test lacks scientific basis.
Whether bones are preserved in the open air or buried in the soil, after a long period of time, the soft tissues will generally dissolve and disappear through decay, and the hair and fingernails will fall off, leaving only the ossified bones.
The surface of bones that have turned into white bones is often corroded and crispy, and anyone dripping with blood will be immersed in them.
And if the bones are not dry, the structure is intact, and there are still soft tissues on the surface, no one's blood will be immersed into it.
After long-term practice, people have realized the uncertainty of bone testing and have doubts about it.
In the Ming Dynasty, some people used the blood drop method to test for paternity, that is, mixing the blood of both parties and then observing whether the mixed blood blended to determine the parent-child relationship.
In comparison, the blood test method is closer to the modern blood type test than the bone test method.
Even if some cases of blood recognition are consistent with reality, this is just accidental and inaccurate.
If we think about this from a physics perspective, blood can dissolve in water regardless of blood type.
Thinking from a biological perspective, as long as two people have the same blood type, they can definitely fuse.
But generally two people with the same blood type are not necessarily related by blood.
Therefore, the "blood recognition" method of judging blood relationship that has been passed down for thousands of years is completely unreliable.
Precisely because of the unreliability of "blood identification", after entering modern society, people first used red blood cell blood types to identify blood relationships.
This has a certain scientific basis.
Because theoretically, when both parents have blood type O, the children cannot have blood types A, B, or AB;
When both parents have blood type B, their children cannot have blood types A or AB.
By analogy, blood relationship can be ruled out.
However, the method of using red blood cell blood types to identify blood relationships can only be used to deny, not to affirm, and the accuracy is not high.
Of course, I believe many people have also heard of the "unexpected incident" regarding paternity testing:
The father has blood type B and the mother has blood type O, but the child was found to have blood type A. Finally, the family did a DNA paternity test and the result was that the child was indeed their biological child.
This is because there is also the Bombay blood group.
The Bombay blood type is extremely rare among Chinese people because there are no A, B, or H antigens on red blood cells. In addition to anti-A and anti-B antibodies, there are also anti-H antibodies in the serum.
Although the mother mentioned in the case is shown to have blood type O, she is actually Bombay blood type and carries the A gene, specifically (hh, AO) or (hh, AA). The father has type B blood, which is (Hh, BO). ) or (HH, BO), after being passed to the child, they combine to form (Hh, AO), so the child's blood type is type A.
Therefore, if the father has type B blood and the mother has type O blood, it is reasonable for the child to be found to have type A blood.
Later, people invented more accurate methods such as leukocyte blood group (antigen) paternity testing and chromosome paternity testing, but they all had certain flaws.
DNA is the most formal way of paternity testing.
DNA (deoxyribonucleic acid) is the genetic information of 46 chromosomes in cells in the human body. Male sperm cells and female eggs each provide 23 chromosomes. Each living organism inherits half of the genetic molecular material from its father, and The other half is obtained from the mother.
DNA identification can be tested on different samples, including blood, hair, saliva, oral cells, etc.
The principle of DNA paternity testing is based on the fact that each person's DNA is unique, just like a fingerprint.
Do a dozen to dozens of DNA loci. If all are the same, the parent-child relationship can be confirmed. If more than 3 loci are different, the paternity relationship can be ruled out.
The accuracy of DNA testing to confirm paternity is as high as 99.99%, and the accuracy of denying paternity is nearly 100%.
If Xu Xian wanted to determine whether Qiao Xiaodie was Qiao San's daughter, she could only use a DNA paternity test.
There are DNA testing machines for sale in the system mall, but they are relatively expensive, costing five thousand taels of silver.
Xu Xian kept all his money in Hangzhou, and he didn't have much money around him. He couldn't afford a DNA testing machine, so he could only get it from Qiao San.
Xu Xian said to Qiao San:
"It's not accurate to shed blood to identify a relative. I have a better method, but it's just more expensive."
In order to prove that he was not crazy, Qiao San did not hesitate at any cost and said:
"Just tell me how much you want. As long as it's not too outrageous, it's fine."
Xu Xian said:
"It's not expensive. It only costs five thousand taels of silver. You can find a piece of Qiao Xiaodie's hair and the results will be available in an hour and a half."
