As winter turns to spring, the six years of Yu’s reign kicks off with the roar of the spiritual locomotive.
Chang'an Jinchengfang,
Li Ang, wearing the best man's attire, was sitting in the side hall of Song Shaoyuan's house, slowly drinking sobering soup.
During the day today, as the best man, he attended the wedding of Song Shaoyuan and You Xiao.
At the wedding, Pu Liuxuan and other academy teachers, Ji Linglang and other fellow students from Zhenzhou, Li Wei and Yang Yu and other academy classmates all attended in their best attires.
As the man's parent, Aunt Song burst into tears - she had raised Song Shaoyuan alone for so many years, and only she knew the pain and suffering.
Fortunately, Li Ang persuaded Aunt Song in time - Song Shaoyuan was ranked above average in the academy and could definitely become a high official. She could just enjoy the blessings in the future.
After finally convincing Aunt Song, after the wedding was over, the guests went back to their homes.
Li Ang and his friends stayed in the side hall, using telekinesis and Fu Lu to help clean up the wedding scene.
It's getting late,
Li Wei, Yang Yu and Yong Hongzhong got together to drink.
Li Leling held Qiu Feng while He Fanshuang chatted.
Chai Chai was so stuffed from the feast that he lay on the recliner and fell asleep.
"So,"
Ji Linglang walked over with a smile and sat down next to Li Ang, "How have you considered my proposal?"
"Again?"
Li Ang rolled his eyes half helplessly and half amused.
After the news spread that he had accepted Ouyang Shi as his disciple some time ago, many people came to visit, hoping that Li Ang would accept more disciples.
For example, the youngest nephew of Yan Guogong Yan Yundang, the younger brother of Ji Linglang, the son and daughter of Dr. So-and-so from the academy...
This is not only because of Li Ang’s reputation and status,
Also because of evidence-based medicine, it has shown strong reliability.
Today's hospitals will record all the patient's physical condition, medication prescriptions, disease process, subsequent healing and other information to find patterns and summarize experiences and lessons.
In this process, a large number of folk remedies have been proven to be ineffective and harmful.
The efficacy of a prescription can no longer be determined by a doctor just by speaking.
The long-standing disdain and distrust of doctors among the people is gradually fading and changing.
Li Ang asked: "Isn't your brother going to take the Academy exam?"
"No test. I've asked my senior brothers and sisters to help me check it out. He doesn't have spiritual talent."
Ji Linglang spread her hands and said there was no great disappointment in her tone—spiritual talent is inherently a random and uncontrollable thing.
The Ji family is not a thousand-year-old family with optimized bloodline. It is a blessing to have one of the three children admitted to the academy.
"He doesn't like the Imperial College very much either. He feels that the products that have changed the Yu State over the years, such as artemisinin and Lingqi motorcycles, all come from the academy. The students taught by the Imperial College will only focus on officialdom."
Ji Linglang curled her lips and said: "He is now a probationary member of the Chang'an Institute of Neo-Confucianism and has published several papers in Neo-Confucian journals."
"Oh? Really?"
Li Ang usually heard Ji Linglang mention her somewhat deviant brother, and asked curiously: "What are the topics of the papers?"
"The effect of different alcohol concentrations on pathogenic bacteria."
Ji Linglang said: "He observed that a solution of half alcohol and half water had an average killing effect on pathogenic bacteria under a microscope.
A solution of 90% alcohol and 10% water can kill a large number of pathogenic bacteria, but there will still be a small amount left.
However, the three-quarter concentration alcohol solution has the highest killing effect.
He suspected that too high a concentration of alcohol solution would extract water from the pathogenic bacteria, dehydrating the surface of the pathogenic bacteria and forming a shell, which would affect the killing effect."
"Oh?"
Li Ang's eyes lit up, "What other papers are there?"
"Uh..."
Ji Linglang thought for a while, "He visited many customers who bought glasses in Chang'an City, and the investigation found that these people's vision did not suddenly become worse, but gradually became myopic.
What they have in common is that most of them are scholars, who like to read by kerosene lamp at night, or hold the book very close to them.
He therefore suspected that myopia was an eye disease caused by lifestyle habits."
Ji Linglang paused and said with some embarrassment: "In addition, he also has a paper about pregnancy verification.
Hu merchants from the Western Regions claimed that in their hometown, the urine of newly married women would be sprinkled on the seeds of barley and wheat. If the barley sprouts first, it proves that a boy will be born.
If the wheat sprouts first, it means that a girl will be born first.
People in Chang'an originally thought this was a joke, but he actually did an experiment and found that the urine of pregnant women can really make seeds germinate. However, it cannot detect whether they are pregnant with a boy or a girl."
Ji Linglang rubbed her palms and her face turned a little red.
Obviously, it doesn’t sound very good if a son of a noble family doesn’t play around with sex and just goes to play with urine.
"Oh?"
Li Ang rubbed his chin with interest. In fact, the estrogen in the urine of pregnant women can indeed promote the germination of seeds. The accuracy of pregnancy tests is as high as 70%.
In addition, there is a bizarre 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 cost and does not kill animals.
The scariest thing is that the clawed frog can be used repeatedly and can be used again after a few days of rest. It can be called a pregnancy test...
"Let him try to take the imperial medical examination first. If he passes, he can accept it."
Li Ang put back his wandering thoughts and said to Ji Linglang.
"Okay."
Ji Linglang quickly agreed and breathed a sigh of relief - after all, their family was also an official family, and it was outrageous for their youngest son to not do his job and play around with shit and piss all day long. He might as well study medicine with Li Ang.
Having solved a worry, Ji Linglang was in a happy mood. She glanced at the glowing glass sphere hanging on the wall and asked casually: "Is this the latest rune lantern?"
"Yeah."
Li Ang nodded. He Fanshuang's action efficiency was much higher than he imagined. Some time ago, he had created the first charm disk with the function of a shimmering charm, which can emit a certain amount of light.
Although in the eyes of outsiders, this talisman lamp is expensive to make, the brightness is not as bright as a large kerosene lamp, and it must be connected to a spiritual energy 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 knows very well that as long as the manufacturing cost of the spiritual energy machine is reduced and the power of the rune lamp is increased, there will be sufficient profits to start large-scale production.
By then, every household will be able to have relatively cheap nighttime lighting.
Aura motorcycles, aura ships, rune lanterns... the technology tree of this world has developed in another direction.
