Chapter 392 Clawed Frog
Winter goes to spring, and the six years of Yu State’s Zaiqian kicked off with the roar of the spiritual locomotive.
Changan Jinchengfang,
Li Ang, who was dressed as the bridesmaid, was sitting in the side hall of Song Shaoyuan's house, slowly drinking sober soup.
Today during the day, as the best man, he attended the wedding of Song Shaoyuan and You Xiao.
At the wedding ceremony, Pu Liuxuan and other school teachers, Ji Linglang and other Shuzhou fellows, and Li Wei Yang Yu and other schoolmates all attended the wedding in full costumes.
As the man’s parent, Aunt Song cried into tears—she raised Song Shaoyuan alone for so many years, and only she knew the bitterness and suffering.
Fortunately, Li Ang persuaded Aunt Song in time—Song Shaoyuan was ranked high in the school's grades, and he would definitely be a high-ranking official. She can enjoy the blessings in the future.
It was hard to persuade Aunt Song. After the wedding ceremony, the guests went back to their homes.
Li Ang and his friends stayed in the side hall, using their thoughts and talismans to help clean up the wedding scene.
The sky is getting late,
Li Wei, Yang Yu and Yong Hongzhong got together to drink,
Li Leling chatted with Qiu Feng and He Fanshuang.
Chai Chai was exhausted from eating, so he lay on the recliner and fell asleep soundly.
"so,"
Ji Linglang walked over with a smile, and sat down next to Li Ang, "How is my proposal going?"
"Again?"
Li Ang rolled his eyes half helplessly and half amusedly.
After the news spread that he had accepted Ouyang Shi as his disciple some time ago, many people came to visit him, wanting Li Ang to accept more disciples.
For example, Yan Yundang’s family, the youngest nephew of Yan Guogong, Ji Linglang’s younger brother, and the son and daughter of Dr. Xuegong
This is because of Li Ang's reputation,
Also because of evidence-based medicine, it has shown strong reliability.
The current ward will record each patient's physical condition, medication prescription, disease process, follow-up healing and other information, search for patterns, and summarize experience and lessons.
In this process, a large number of folk remedies have been proved to be ineffective and harmful.
The curative effect of a prescription is no longer something a doctor can say by just moving his mouth.
For a long time, the people's contempt and distrust of doctors is fading and turning around bit by bit.
Li Ang asked: "Isn't your younger brother going to the Academy?"
"No test. I have already asked my senior brothers and sisters to help me read it. He has no talent for spiritual veins."
Ji Linglang spread her hands, and her tone was not too disappointed—the talent of spiritual veins is a random and uncontrollable thing.
The Ji family is not a thousand-year-old family whose blood has been optimized. One of the three children was admitted to the school, thank God.
"He doesn't like Guozijian very much either. He thinks that over the years, the products that have changed the state of Yu, such as artemisinin and spiritual locomotives, all come from the academy. The students taught by Guozijian will only focus on the officialdom."
Ji Linglang curled her lips and said: "He is now a probationary member of the Chang'an Science Society, and has published several papers in science journals."
"Oh? Really?"
Li Ang usually heard Ji Linglang mentioning her somewhat rebellious younger brother, and asked curiously: "What are the themes of the papers?"
Ji Linglang said: "He observed that the solution of half alcohol and half water, under the microscope, has a general killing effect on pathogenic bacteria.
A solution of 90% alcohol and 10% water can kill a large number of pathogenic bacteria, but there is still a small amount of residue.
The 3/4 concentration of alcohol solution has the highest killing effect.
He suspects that an excessively high concentration of alcohol solution will extract the water in the pathogenic bacteria, dehydrate the surface of the pathogenic bacteria, form a shell, and affect the killing effect. "
"oh?"
Li Ang's eyes lit up, "Any more papers?"
"Well"
Ji Linglang thought for a while, "He visited many customers who bought glasses in Chang'an City, and the investigation found that the eyesight of these people did not suddenly deteriorate, but gradually became myopic.
What they have in common is that most of them are scholars, and they like to read by a kerosene lamp at night, or hold the book very close.
He therefore suspects that myopia is an eye disease caused by living habits. "
Ji Linglang paused for a moment, and said with some embarrassment: "In addition, he has a paper on pregnancy verification.
Hu merchants in the Western Regions claimed that in their hometown, they would sprinkle the urine of newlywed women on the seeds of barley and wheat. If the barley germinates first, it proves that boys will be born,
If the wheat germinates first, it proves that the father will give birth to the girl.
People in Chang'an originally listened to this as a joke, but he really did an experiment and found that the urine of pregnant women can really make seeds germinate. But it is not possible to detect whether it is pregnant with a man or a woman. "
Ji Linglang rubbed her palms together, her face turned red.
Obviously, a son of an official family doesn't play sensuality, but goes to play with urine. It's not very nice to say it.
"oh?"
Li Ang rubbed his chin with great interest. In fact, the estrogen in the urine of pregnant women can indeed promote the germination of seeds. The accuracy rate for pregnancy testing is as high as 70%.
In addition, there is also a strange pregnancy test method-injecting a small amount of human women's urine into female clawed frogs that are more than one year old,
If the clawed frog lays a string of black and white eggs within 5-12 hours, it proves that it has been stimulated by estrogen, which in turn proves that human women are indeed pregnant.
This method is low in cost, does not kill life,
The most terrifying thing is that the clawed frog can be used repeatedly, and it can be used again after a few days of rest. It can be called a pregnancy test artifact
"Let him try to take the examination of the Imperial Medical Office first. If he passes the examination, he can accept it."
Li Ang withdrew his wandering thoughts and said to Ji Linglang.
"good."
Ji Linglang quickly agreed, and quietly breathed a sigh of relief—after all, their family is also an official family, and the youngest son in the family is not doing his job properly, and it is shameful to play **** and fart all day. It is better to study medicine with Li Ang.
Having solved a problem, Ji Linglang was in a happy mood, glanced at the glowing glass sphere hanging on the wall, and asked casually, "Is this the latest talisman lamp?"
"Um."
Li Ang nodded. He Fanshuang's action efficiency was much higher than he imagined. Some time ago, he had created the first talisman plate with the function of a low-light talisman, which could emit a certain amount of light.
Although in the eyes of outsiders, this talisman lamp is expensive, and its brightness is not as good as a large-scale kerosene lamp, and it must be connected to a spiritual machine, or a certain amount of spiritual energy must be poured into it every day, so it is not affordable in any way.
But Li Ang is very clear that as long as the manufacturing cost of the spiritual energy machine is reduced and the power of the talisman lamp is increased, there will be sufficient profits to start large-scale production.
By then, every household will have relatively cheap night lighting.
Aura locomotive, aura ship, talisman lamp... The technology tree of this world has already developed in another direction.
