Ask Sword

The weather is so nice.

Li Ang walked out of the examination room in a happy mood, stretched his waist, and sat on the stone bench under the shade of the trees in the courtyard to rest for a while.

The shadows of the trees are mottled, the cool breeze is blowing, and the cicadas are singing. Through the doors and windows of the examination room, you can see the students inside holding pens and thinking hard.

This familiar and intimate feeling made Li Ang couldn't help but smile, and the irritability of the past few days subsided quietly. He put his hand on the stone table and flicked the fallen leaves away.

Tread Tread.

With the sound of slight footsteps, a girl named He Fanshuang with Liu Yemei briskly walked out of the examination room with a rare faint smile on her face.

She clasped her right index finger with her left hand behind her back, bent slightly, and sniffed the blooming gardenias outside the examination room, feeling very happy.

But when she raised her head and saw that there was already an examinee in the courtyard, and that examinee happened to be Li Ang,

The smile on his face quickly disappeared, and he returned to his original expressionless appearance.

Glancing at Li Ang, he turned and walked out of the courtyard.

What is this?

Xueba handed in the papers ahead of time, only to find out that someone had finished all the questions earlier than himself, was he inexplicably angry?

Li Ang laughed dumbfounded at Liu Yemei's petty temper, shook his head, seeing that Song Shaoyuan and others hadn't come out for a long time, he also got up and walked to the gate of Suzaku in the imperial city.

Outside the Suzaku Gate, there are strong and sharp Jinwu guards on duty, forming a circle to prevent the imperial city avenue from being congested by the family members of the examinees.

The many family members who were waiting anxiously with parasols saw an examinee come out, and hurriedly surrounded them, asking all over the place, What questions did Mr. Xiao Lang get in this year's exam?

Xiao Langjun, do you think the questions are difficult? Last time my Sanlang tried 2,600 students, can he pass this re-examination?

Xiao Langjun, did you hand in the paper in advance?

The noisy voices instantly filled Li Ang's ears. He had to hide behind the helpless Jinwu guards and said loudly to the parents of all the candidates: This year's retest is more difficult.

But I believe that the many students who have cultivated their ideals with wisdom, watered their hopes with sweat, and crossed the vast sea of ​​learning will definitely do their best to live up to the expectations of their parents, the high expectations of their mentors, and the wisdom bestowed by God. Bearing the ideal of youth, ten years of hard work, one day to realize the dream, good news spreads, and the title of the gold list!

After finishing speaking, he bowed his hands heavily, slipped out of the gaping crowd, and came to Zhuque Street.

Stop coughing, Dalang, this way!

Chai Cuiqiao's voice came from the front of her head, and she saw her little maid standing by the window of the wing room of the restaurant outside the main entrance of the imperial city, waving to herself, and sitting next to her was a girl with a light veil on her face.

It should be the new friend Chai Cuiqiao mentioned before, Li Leling, right?

Li Ang stepped up to the restaurant, and saw more than 20 guards and maids outside the door - it's not surprising that the favored children of Xungui's family are all in this configuration.

Before Li Ang pushed open the door of the wing room, the door opened by itself from the inside.

Chai Cuiqiao held up the pastry, blinked her big eyes, and asked nervously, Dalang, how about the retest?

It's okay, that's all.

Li Ang said casually, and cupped his hands at the veiled girl, Yuzhou, Li Ang.

Well

The Qingsha girl seemed not used to introducing herself, she paused for a moment, then stood up, and said softly, Chang'an, Li Leling.

Isn't it XX Fang, Li Leling?

Li Ang thought casually.

People from Chang'an who live under the imperial city are warm and enthusiastic, but at the same time a little arrogant. Generally, when introducing themselves, they will add a certain city in front of it,

For example, Yang Yu in Chonghuafang and Qiu Jinghuan in Yongjiafang.

The better the conditions in the workshop and the richer it is, the more it is like this.

Li Leling blinked, and asked softly, Did Mr. Li Jiada also hand in the paper early today?

Well

No matter how many times, Li Ang is still not used to the intimacy of Da Lang, nodded and said: Well, all the exam questions are done, so I just came out first.

Chai Cuiqiao said proudly: Hey, my Dalang is very good. He got second in the first test last time. How can he come back with a score of 1, 2, 3, 4, 5, 67 this time?

Li Ang rolled his eyes at Chai Cuiqiao, Is the avatar technique?

Second in the primary exam?

The maids on the side opened their eyes wide in surprise, and Li Leling also tilted her head slightly—although she grew up in a deep palace because of congenital heart disease since she was a child, she still knows some basic common sense.

The second place in the school entrance examination

Should be considered very powerful, right?

hey-hey,

Chai Cuiqiao proudly waved the pastry in her hands, and said to the surprised Li Leling and the other maids, My Da Lang is not only highly educated, but also skilled in medicine. He even treated a senior official's illness a few days ago.

In addition, he also knows gynecology, and he can treat abdominal pain, calf cramps, and dystocia.

Oh yes, he also invented.

Stop.

Li Ang clutched his forehead, and quickly interrupted Chai Cuiqiao's boasting that was getting more and more crooked.

What Chai Cuiqiao wants to talk about is actually the improvement of the moon cloth. Since Xuegong improved the cotton planting method and invented the cotton gin (to remove cotton seeds) and the spinning wheel, cotton batting and cotton cloth have begun to be produced in various parts of Yu State.

However, the degreasing process is still relatively backward, and the hydrophobic lipids on the surface of cotton wool are not removed, and the water absorption effect is not good.

And the presence of lipids is also easy to adsorb bacteria.

So Li Ang thought of a way, first tear the cotton to remove impurities, wash it with water, put it in a casserole, pour distilled water and 3% caustic soda,

(Slaked lime and soda ash are mixed to form calcium carbonate and caustic soda)

Cover and bring to a boil, then simmer for ten minutes on low heat.

After the cotton has cooled, rinse it again with water, let it dry,

The end result is a cotton wool ball.

Absorbent cotton is easier to absorb liquid than ordinary cotton. It is odorless, tasteless, and colorless. It is white and elastic, and it is not easy to breed bacteria. It is very suitable for making sanitary tampons-alcohol disinfection and so on.

At the same time, absorbent cotton is also very suitable for coughing, as a monthly cloth.

If this news spreads now, Li Ang doesn't want to be admitted to the academy with the reputation of a somewhat strange gynecologist, at least until after he is admitted.

There is a patent institution in the academy, and the inventions and creations of doctors and students can be registered in the academy.

If a businessman in Yu State wants to produce,

It’s fine for small local businessmen to produce secretly by themselves. Large-scale companies have to pay a very small amount of patent fees when they put into large-scale production.

Naturally, there is no need to bow down for five buckets of rice and run to help dignitaries build houses with the power of thoughts and talismans.

In addition, the inventions produced by the academy are easier for the public to accept, which is more conducive to subsequent large-scale promotion.

‘Should we register patents anonymously? It would be weird to be nicknamed the Guardian of the Gynecology'

Li Ang suddenly recalled, ‘Speaking of which, is the blueprint of my midwifery forceps still with Senior Brother Cheng? '

————

Yu State, Hedong Road, Wendeng County.

Cheng Juxiu, who was a little tanned, sneezed suddenly while sitting in the courtyard.

Juxiu, what's wrong?

Sitting opposite Cheng Juxiu, a doctor named Gongyang Deming, who looked like an ordinary old man, asked with a frown.

It's nothing, it's just that I was blown too much by the sea breeze and caught a little cold.

Cheng Juxiu waved his hand, and was about to say something when he was interrupted by the baby crying in the room.

gave birth?

Cheng Juxiu, Gongyang Deming, and four other male and female academy disciples stood up and looked into the room.

Not long after, the door opened,

Han Qingyun and another female disciple, each holding one side of the silver midwifery forceps, walked out of the house, nodded to Cheng Juxiu and the others, Mother and daughter are safe. There is a stable woman in the room to take care of them, and they are fine.

Huh, that's good.

Cheng Juxiu heaved a sigh of relief, the school respects benevolence and righteousness, even if the women in the delivery room are just fishermen who have never met them, they will try their best to save them when they see them.

in addition.

The expression on Han Qingyun's face was a little strange, This forceps is really ingenious.

Clamp the fetus' head with the left and right leaves, and gently pull it outward to assist delivery.

With this pliers, there will be far fewer women dying of dystocia in the future.

It's amazing, my junior brother invented it.

Cheng Juxiu said with a smile: In the past, women who gave birth had to rely on themselves to earn their own lives.

Or by the minder, use the power of mind to pull the fetus to midwifery.

But there are not many mentors in the world, and very few are willing to help pregnant women give birth, and there are even fewer mentors who have sufficient precision, accuracy, and strength of mindfulness.

It is not an exaggeration to say that the midwifery forceps are Buddhas of all families.

Cheng Juxiu paused for a moment, and added: Just pay attention to the strength of the forceps.

It must be delicate and precise so as not to harm the mother and fetus.

Before going to Xuegong to register patents and mass-produce, it is necessary to publish instructions for use in Xuegong newspapers.

Let midwives from all over the world use peaches and other objects to practice more frequently.

Okay, look at your excited look, you were never so happy when you solved that monster before.

Ram Deming shook his head and smiled.

He is one of the Ph.D. professors of engineering at the academy, and in Daodengzhou in the east of the river, he presides over the construction of ocean-going ships that can cross endless seas.

Some time ago, fishermen and sailors in Dengzhou Port reported that they saw small islands with a diameter of 30 feet in the sea when they went out to sea.

There are trees and shady grasslands on the island, and seabirds roost on it.

However, eyewitness reports show that the location of the island is not fixed and often moves.

Ram Deming and his students went to check, used the water-avoiding charm to dive into the bottom of the sea, and saw the main body of the island—a giant three-legged hawksbill monster with a body length of more than 200 meters.

It is classified into demon-two-one one three, ben blame turtle.

Erya Shiyu says: Turtle, three-legged, capable; turtle, three-legged, ben.

Book of Changes says: Bai Ben is not to blame. Hence the name Ben Jiu.

This second-level monster has a docile personality. In the few witnesses, it likes to float under the sea, open its mouth, and eat passing algae, fish, squid, etc.

Sometimes it also dives into the deep sea and nibbles on the mud and rocks on the bottom of the sea-this behavior may be for digestion.

Benji turtles usually live in the depths of the endless sea, and rarely come to the coast, and rarely attack ships.

However, such a huge monster is a second-level monster after all, and it is always a hidden danger to stay outside Dengzhou Port.

Gongyang Deming and his students came up with a way to put a large piece of whale meat smeared with special oil in a fishing net, dragged by a sea boat in front, and used the smell of fish meat to attract the turtle and slowly lead it away. Back to the endless sea.

In the process of leading back to the Endless Sea, Gongyang Deming and others also took the opportunity to collect a large number of samples from the body of the docile and docile Benji turtle.

Including but not limited to the monster carnivorous barnacles parasitizing on the abdomen of Benjiao turtle;

The spice tree that grows on the back of the Benji turtle;

And the special metal grown on the carapace on the back of the Benjiu turtle - this metal is indestructible and has superior performance, and can be used to forge flying swords, armor and even the core components of the keel of sea ships.

Just deal with the Benji turtle, or digging for treasures happily,

It took everyone a month, and now they are finally free, and happened to meet a fisherman's mother with dystocia, so she came to help with forceps - by the way, to test the actual effect of forceps.

After all, Ben Jiugui is too gentle.

Cheng Juxiu spread his palms helplessly. Although his animal science in the academy is good, he still prefers the engineering of forging things, By the way, Mr. Gongyang, now we have the carapace samples of the Benji tortoise, and the construction of refined iron sea ships can Are you speeding up?

Well, wait until September, when the manpower and material resources of the Ministry of Industry are in place, and the construction can start.

Gongyang Deming nodded, You and Qingyun should go back to Chang'an first. I will trouble you this time.

Oh, by the way, bring back the record of Ben Jiugui I wrote, and the report on the use of midwifery forceps this time - His Majesty and the head of the mountain will be very happy about it.

Wait for the transfer order from the Ministry of Industry in September, and then you will return to Dengzhou by yourself.

OK.

Cheng Juxiu nodded in agreement, took the cleaned midwifery forceps handed over by Han Qingyun, put them in an iron box, and put them together with a large piece of Benjiu metal,

Suddenly a thought came to my mind, 'Calculate the time, it's almost time for the re-examination or the third examination at the academy?

I don't know how Risheng's grades are, so it shouldn't be in trouble, right? '

(Author's note: It will be put on the shelves in the early morning tonight, and there will be more updates.)
