Chapter 119 Parent inspection
The three of Li Ang once again declined Monk Jing’s invitation to listen to the lecture, and left Jing Temple.
Yang Yu was still muttering when he boarded the carriage, "How come even the Nestorians have learned street fortune-telling tricks, and when they meet, they tell people that the Yintang is black and bloody."
Li Wei curled his lips and said: "How else can we recruit believers and earn incense money?"
The three of them are still wearing school badges. For Nestorianism, if a school disciple can become a believer, the gold content must be much higher than that of ordinary believers.
Li Ang also didn't believe the theory of bloodshed, so he returned home in a carriage, thought for a while and took Chai Chai out of the house, called Song Shaoyuan, You Duzhi and some friends, and went to a restaurant to have a good meal together, as Christmas up.
"The radish pork rib soup in this Jinchengfang restaurant is quite delicious. Come over and try it when you have time. Eat radish in winter and **** in summer."
Li Ang filled a bowl of soup for himself and Chai Chai, and said, "It may be a good thing to drink soup."
"Should we eat more radishes in winter?"
Yang Yu's eyes lit up, "Is this also medical theory?"
Song Shaoyuan thought for a while and said: ""Treatise on Febrile Diseases" says: In November, Yang Qi is inside, and the stomach is troubled and hot, and Yin Qi is weak inside and cannot overcome the heat.
Maybe eating radishes in winter can clear up accumulated heat? "
Can’t radish be delicious? By the way, Brother Song, your reading has been a bit complicated recently.
Li Ang smacked his lips, and decided not to speak anymore—looking at the expressions on Yang Yu's and the others' faces, it is estimated that they will start eating carrot soup at home after returning.
Since he was admitted to the academy, Li Ang's habits in life have been imitated by the Chang'an family inexplicably.
For example, never eat uncooked river fresh seafood, insist on washing hands with soap before and after meals, and only drink filtered and boiled water,
Even the cotton mask that Li Ang occasionally wears, imitators have already appeared on the street.
There is a strange sense of sight that he has become the leader of the fashion trend in Chang'an City.
Li Ang originally wanted to correct this weird trend, but after thinking about it, it would at least help promote public health habits, so he let it go.
By the way, there seems to be no stewed noodles with pork and sauerkraut on the table.
Vermicelli can be made from miscellaneous grains, but Chinese cabbage, the raw material of sauerkraut, does not seem to be available in Yu State. It can only be produced by cross-evolution of cruciferous southern cabbage and northern turnip.
Li Ang was thinking about improving the recipe while eating radish rib soup.
The current main vegetable in the country of Yu is sunflower. This kind of mallow vegetable tastes creamy like fat and has a slightly astringent taste.
Many doctors of agriculture in the academy have tried to improve the taste of sunflower, but they have not been successful. I had no choice but to turn my attention to the rich vegetable varieties beyond the endless sea.
Maybe it's time to hybridize Chinese cabbage someday?
Li Ang was thinking about various ways to improve the food, and suddenly, there was a slight cry and conversation in the next cubicle.
Yang Yu and the others looked at each other. They wanted to continue eating, but when they listened carefully, the voice seemed to be a female student from the academy?
"Sunrise."
Yang Yu stood up subconsciously, and glanced at Li Ang nervously, "Shall I go and have a look?"
"I'll go too."
Li Ang pressed the table helplessly and stood up. The voice seemed to be that of a female classmate named Zhang Yuyan, who came from an official family, and Yang Yu had a good impression of her.
Li Ang and Yang Yu pushed the door out and knocked on the door of the next room. After confirming their identities, it was Qiu Feng, the daughter of the imperial doctor who opened the door. There were several other schoolmates in the room, as well as a mother and child.
"What, we were eating next door just now. What happened?"
Yang Yu asked, and after talking, he found out that it was those things in the big family again.
Zhang Yuyan's father was the Minister of the Household Department, and her grandfather was once the prime minister of Yu State and was appointed Duke of the State. The Zhang family cannot be said to be noble in Chang'an, at least they are also rich.
The Zhang family has a housewife and seven concubines. That Zhang Shilang especially doted on a concubine's room, but some time ago, Zhang Shilang always felt that the seven-year-old son born in the concubine's room was less and less like himself.
Generally, the Chang'an family handles such matters in a ruthless and ruthless manner.
But Zhang Yuyan is the daughter of another concubine, she has a very good relationship with that concubine, and treats her as her own aunt,
Even if the Zhang family wanted to get rid of the concubine silently, they still had to consider the thoughts of Zhang Yuyan, a disciple of the academy.
Later, for some reason, this matter was leaked in the market,
In order to get rid of the suspicion of being green, and to let the concubine's innocence, Zhang Shilang adopted the method of blood test.
As for the results of the parent test
The blood does not mix, and the concubine and her son are also kicked out and live on the streets.
At this moment, Zhang Yuyan was crying and sad because of this incident.
It can only be said that it is worthy of being a family, there are many bad things.
Li Ang rubbed the center of his brows, glanced at Zhang Yuyan who was crying like pear blossoms with rain, the concubine's mother and son, and Qiu Feng, Yang Yu and other schoolmates who were comforting in a low voice, and sighed.
Zhang Yuyan was born in a family of officials and eunuchs, and she has a lot of pocket money every month. By secretly saving money, she can rent a house and support her concubine, mother and child.
But without identity certificates and titles, concubines, mothers and children must be looked down upon by others, and life is difficult.
"May I ask,"
Li Ang thought for a while and asked: "The Zhang family's blood test method before, is it the blood method or the bone method?"
The combined blood method and the bone dropping method are both methods for testing relatives by dropping blood.
The former is to take the blood of two people and drop it into a bowl to see if it can blend.
If they can be compatible, it proves that there is a blood relationship, but if they can't, there is no blood relationship.
The bone drip method is to drop the blood of a living person on the bones of a dead person to see if it penetrates. If it can penetrate, it proves that it is a blood relative.
During the Southern Dynasties, Emperor Wu of Liang begged for a concubine from the Marquis of Donghun, and the concubine gave birth to Xiao Zong in July after entering the palace.
Everyone in the palace suspected that Xiao Zong was not the biological son of Emperor Wu of Liang. Even Xiao Zong himself was suspicious. He secretly went to dig the tomb of Marquis Donghun, dug out the bones, dripped his own blood on the bones, and sure enough, he could blend into it.
In order to verify, he also killed his own son and repeated the experiment.
After confirmation, he fled to the Northern Wei Dynasty.
In addition, there are stories of sailors who died at sea, the corpses of the same ship rotted, and the family members of the sailors did a blood test to find the dead bodies of their family members.
Seeing Li Ang asking, Zhang Yuyan wiped the tears from her face and said, "It's the blood law."
"Blood Synthesis"
Li Ang lowered his head and fell into thought. Yang Yu saw the pensive expression on his face, and subconsciously asked, "Risheng, what are you thinking?"
"I was thinking that the blood test is completely wrong, and there is no way to prove whether there is a blood relationship."
Li Ang raised his head and said, "Wait until tomorrow when we go to school.
It's time to bring the blood type theory to the table.
Hearing Li Ang's promise, Yang Yu was overjoyed, and the other students felt relieved—everyone knew that Li Ang would do what he said and what he would do.
He said that if there is a way, it may really be able to solve it.
The meal ended hastily, and Yang Yu paid for it, and found a hotel to settle down the Zhang family's concubine, mother and son,
And Li Ang returned home, took out a pen and paper, and wrote down the experimental plan.
——
In the early morning of the next day, Yang Yu came to Jinchengfang in a carriage early, and asked Li Ang about his progress as soon as they met.
"No hurries,"
Li Ang rolled his eyes, "The erroneous notion of blood test has persisted for so many years, if we want to overthrow it, we have to come up with a more reasonable proof method.
It’s not something I can do by writing some articles at home. "
"Isn't this trusting you, Risheng?"
Yang Yu rubbed his palms, flatteringly said: "Risheng, how do you plan to prove it?"
"Look for Dr. Su Feng, apply for large-scale experiments, and publish papers in academic journals."
Li Ang said casually: "But this is just to prove that the blood test is completely invalid,
It is still difficult to use blood to prove paternity. "
Yang Yu subconsciously asked, "Hey, why?"
Li Ang asked back: "The process is very complicated, are you sure you understand?"
".All right."
Yang Yu thought for a while, waved his hand a little guilty, and didn't continue to ask - obviously he was also an elite student who was admitted to the academy, and he lost his confidence when Li Ang asked him.
The carriage drove into the entrance palace, and after a science class, Li Ang found Su Feng, a doctor of science.
"Oh, the rising sun."
Su Feng said: "Yesterday, the representative of the Xijing Chamber of Commerce in Chang'an also approached, saying that they hoped to have the right to resell part of the soap and soap, and wanted to sell the soap and soap produced in Yu State back to Xijing.
Hu Chamber of Commerce also has this idea.
Do you think someday you will meet with them and have a talk? "
"Uh, yes."
Li Ang nodded and agreed, Yu State does not allow the outflow of technology, but it is completely acceptable to sell goods to foreign countries to earn money.
"By the way, Dr. Su Feng, this is the paper I wrote yesterday, and I hope to apply for a large-scale experiment in the afternoon."
Li Ang took out a paper full of words from his bag and handed it to Su Feng. The Academy has always had a tradition of conducting large-scale experiments.
If some doctors have new theories, new inventions, and new experimental plans, they will invite Dr. Xuegong and his disciples to visit together.
For example, new waterwheels, farm tools, and even the model airplanes that were popular in the academy some time ago.
"Do you want to falsify the blood test?"
Su Feng scanned the paper, his eyes lit up, and after confirming that there were no obvious omissions in the experiment process, he immediately agreed to the experiment application.
The location is Xuegong Square, and the time is in the afternoon.
Soon, the notice of the large-scale experiment to falsify the blood test was posted in every corner of the academy square.
By the afternoon, many doctors and classmates from the Academy had arrived in the Academy Square—those who dared to apply for large-scale experiments, most of them were doctors with qualifications, prestige, and achievements, and they had never heard of new students.
What's more, it was some time ago that a new generation of model airplanes was invented.
"Almost everyone has arrived?"
Li Ang glanced at the number of people sitting on the stool, and without procrastination, he asked Yang Yu and Li Wei to hand out a large stack of newly printed papers, while he stood in front of the stage.
"Everyone, teachers and students, today I am here to falsify the blood-drip test that has lasted for hundreds of years."
Li Ang took out five bones from the audience, and said loudly: "These ten bones are the old and new leg bones of pigs, cows, sheep, horses, and donkeys.
The new one was butchered in the school cafeteria yesterday,
Old ones are taken from the Chang'an slaughterhouse and have been stored for at least six months. "
Then, he took out five glass jars containing blood and showed them to Dr. Xuegong and his disciples.
"These jars also contain the fresh blood of pigs, cows, sheep, horses, and donkeys."
Li Ang said: "According to the records of the bone drop method in the blood drop test, it is only necessary to drop the blood of a living person on the bones of a dead person and observe whether it seeps in to prove whether there is a blood relationship.
Now I drip the blood of livestock into the bones of different livestock to see what happens. "
With the help of Yang Yu and Li Wei, Li Ang dipped some livestock blood in a glass jar, dripped it on the old animal bones, and found that it could blend.
"The blood of a pig can penetrate into the bones of a cow.
The blood of sheep can penetrate into the bones of donkeys. This is obviously not in line with common sense. Are pigs and cows, sheep and donkeys related?
I used old bones just now, so what about new ones. "
Li Ang took fresh blood again and dripped it on the surface of the fresh animal bones, but the onlookers found that the penetration rate of the blood slowed down a lot this time, and it was even impossible to penetrate.
"why is that?"
Dr. Xue Gong asked.
"It's very simple, the bone gap."
Li Ang said: "The old bones can penetrate blood, but the new bones cannot. It is completely the difference between the old and new bones.
The muscle and fascia on the surface of the old bone fall off,
The bone itself is weathered, with tiny cracks through which most liquids can easily penetrate.
Teachers and students can also go home to conduct similar experiments, even if the water stained with paint is dripped on the old and damaged livestock bones, it can still penetrate.
So the bone dropping method in the blood test is completely useless. "
There is no difference between livestock and humans. The bones of livestock can penetrate, and the same is true for human bones.
"The dripping bone method is useless, so Xiao Zong's son died in vain."
Another Xuegong doctor whispered.
"It should be said that he died unjustly."
Li Ang said: "Next, I want to prove that it is not only the bone dropping method that is useless. The combined blood method in the blood dropping test is also useless."
