Author: There are dragons in Nanshan

After consultation at the Imperial Hospital, Mei Chun did not hurt the internal organs.

The left forearm was broken, the elbow was dislocated, the ribs were broken, and there were a large area of ​​abrasion on the cheek. In general, it was all external trauma.

Zhu Qizhen then felt relieved. It was a blessing that he could still jump around when he fell from a high altitude.

"Flying over from Nanjing, are you afraid of your life?"

Mei Chun said with a guilty smile on her face, "The student was shocked by the emperor and hoped that the emperor would forgive him!"

"Okay, don't say anything!"

Zhu Qizhen waved his hand and said, "I'll find you a place to stay and be relieved to heal your wounds, next..."

Mei Chun was about to thank her, but she found that the emperor was halfway through and suddenly stopped.

He was a little confused, but he didn't know what to do.

"You wait, wait! Huai'en, take the people well!"

Zhu Qizhen threw a word and left in a hurry.

Mei Chun scratched her head, but accidentally pulled the wound on her arm, grinning in pain.

Huaien hurried forward and said, "Mr. Mei, what's wrong with you? Our family will help you invite the imperial physician!"

"No, no!"

Mei Chun waved his hand and then asked, "Master-in-law, what does the emperor mean?"

Huaien shook his head helplessly and said, "We don't know either."

After about a cup of tea, Zhu Qizhen hurried over with Belin.

"That's this person!"

Zhu Qizhen pointed his hand, and Belin walked forward with curiosity on his face and asked, "Can Kongming Lantern really carry people?"

Mei Chun nodded dullly, and just as she was about to reply, Belin asked impatiently: "How to control the altitude and flight direction?"

"this……"

Mei Chun hesitated for a moment, then said: "In fact, it is to enlarge the folk Kongming lantern ten times, heat it with lamp oil, and then it can rise. Just extinguish it when it needs to land. As for the direction... the students don't know how to control it for the time being, they have to look at the direction of the wind.

However, the wind direction at high altitude varies greatly from the ground, and the airflow runs back and forth, and it depends entirely on luck to fly."

Belin asked again, "What material are you using?"

"There is cowhide on top and rattan underneath."

“Is the production process difficult?”

"It's not difficult...hiss!"

Mei Chun shook her head slowly, but there was a injury on her neck and couldn't help but grin.

"...The cowhide needs to be made of high-quality materials, and the interfaces should be sewn tightly, so there is nothing else."

Belin turned around and said, "Master, it's feasible!"

Zhu Qizhen nodded and said, "No need to delay, set up the Kongming lantern research institute immediately and make a batch of samples first to see how the effect is."

"yes!"

Belin turned around and left, walked to the door and turned back, saying, "The Academy of Sciences has moved to the new Xishan base, and this person's injuries..."

"Carry it to the west mountain and raise it, you are responsible!"

Zhu Qizhen did not hesitate at all and was not willing to wait for a second.

Because he had realized what strategic value the manned Kongming lantern created by Mei Chun has.

Uszang has an average altitude of more than 4,000 meters, and conventional combat methods are difficult to work. Even if you win in the end, you will pay a huge price.

But who said that we must attack from land?

"yes!"

Beilin hurriedly went down to make arrangements, but Mei Chun was a little confused and confused.

Zhu Qizhen explained: "Your family will suffer a little. Go to Xishan to recuperate first. You can be mainly responsible for guiding work in the early stage."

"ah……"

Mei Chun was even more confused, with a question mark on her face.

Seeing this, Zhu Qizhen asked, "What questions do you have in your family?"

Mei Chun thought for a long time before saying, "Your Majesty, the student missed the spring exam..."

"What are you doing? Just go to the Academy of Sciences to appoint you!"

Zhu Qizhen waved his hand at him, and he should have been admitted to such a talented contestant.

Mei Chun said carefully: "Is this... not suitable?"

"Aren't you a juren from Yingtian Mansion?"

"yes……"

"Journalist is enough. Besides, the Academy of Sciences is different from other yamen. Even if you don't have fame and fortune, you can still serve!"

Mei Chun wanted to ask something, but when she saw the emperor's impatient look, she swallowed it back when she said something.

Then, he saw a group of people rushing in, carrying a stretcher...

The Kongming Lantern Research Institute of the Academy of Sciences was urgently established at the Xishan New Base.

The head of the institute is Mei Chun, and the members are selected by Belin himself.

Even Belin herself took off from the power laboratory and devoted herself to the research and development of Kongming lanterns.

In fact, the production process of Kongming lanterns is very simple, and can be made with paper in folk. Kongming lanterns made by the Academy of Sciences are other uses, and they need to use leather.

Soon, most of the cowhide on the market was wiped out, and the cowhide was gone, so they bought sheepskin, or even dogskin. In the end, even the old shop selling donkey skin donkey gelatin was cut off.

Next, the key to this research is high airflow.

The ancients began to study the weather very early. Mei Chun discovered many similar books when copying ancient books.

For example, Zhuangzi in the Warring States Period proposed that the formation of wind comes from the influence of air flow, and mentioned that sunlight and wind can evaporate water, further affecting the direction of the size of the wind.

Relevant legal systems were formed in the Qin Dynasty, and localities must report rain to the court, as well as the area of ​​the world that was affected by rain or weather disasters.

In the Han Dynasty, the "Twenty-Four Solar Terms" were included in the "Taichu Calendar" during the reign of Emperor Wu of the Western Han Dynasty. As a supplement to the calendar to guide agricultural affairs, the Solar Terms were measured in the Yellow River Basin using the Guibei Shadow method.

In the book "Lunheng" by Wang Chong, an philosopher of the Eastern Han Dynasty, it points out that the formation of lightning is related to the solar heat and seasons, and thunder is caused by explosions. Ying Shao's "Common Meaning of Customs" proposes names such as plum rain and trade winds.

During the Three Kingdoms period, people further mastered the relationship between the solar terms and the movement of the sun. In the "Zhoufeng Summary" noted by Zhao Junqing, the "Seven Fights and Six Balances" was introduced, which theoretically explained the relationship between the twenty-four solar terms and the movement of the sun.

During the Jin Dynasty, "Fengfeng Wood Bird" and instruments for determining wind direction were popular. Jiang Ji pointed out that when the floating clouds close to the ground could make the star's sight distance smaller, and make the morning and evening red.

"Trek" proposes the concept of plum rain.

Jia Siyi of the Northern Wei Dynasty fully explored the impact of meteorology on agriculture, and proposed methods to prevent frost with smoke and use snow to kill insects and retain soil moisture; the Northern Wei Dynasty calendar "Zhengguang Calendar" included seventy-two climates in

Almanac; "Jingchu Sui Shi Ji" by Liang Zongyan of the Southern Dynasty, which divides the coldest and hottest seasons of the year.

During the Sui and Tang Dynasties and Five Dynasties, Wang Bing divided the climate of the Central Plains according to the region. Du Taiqing's "Yuzhu Bao Book" excerpts the solar terms, government orders, agricultural affairs, customs, allusions, etc. recorded in various books before the Sui Dynasty, and preserved a large number of lost agricultural meteorological texts.

, Li Chunfeng's "Yizhan" records the structure, installation and usage of the wind measuring instrument.

The Song Dynasty had a richer and more detailed understanding of meteorology, and was more accurate in the prediction and calculation of rain and snow.

"Dream of Dreams" by Shen Kuo, a geographer of the Northern Song Dynasty, involved the weather such as Emei treasure light, lightning, thunder axe, rainbow, Dengzhouhai City, sheep horn whirlwind, bamboo fossils, tiles and frost painting, hail shape, and boating method

, vertical climate zone, weather forecast, etc.

In the Southern Song Dynasty, Jiushao's "Nine Chapters of the Numbers of Books" in Jiushao, Qin of Shaoxing, listed four formulas for measuring rain and snow, explaining how to calculate the depth of rain and snow on the flat ground.

Then, the book "Tian Family Miscellaneous Zha" written by Lou Yuanli in the late Yuan Dynasty and early Ming Dynasty was divided into three volumes: upper, middle and lower volumes. The first volume is from the first lunar month to the 12th lunar month, and the divination is recorded according to the day every month. The middle volume is based on the middle volume.

Astronomical phenomena, today, moon, stars, atmospheric optics and changes in clouds, objects, namely birds, beasts, grass, woods, fish, mountains, water, tides, etc., classified, using a large number of weather, meteorological proverbs to predict the evolution of weather, climate

Changes and abundance of agriculture. The second volume is 300, 600, 600, climate, auspiciousness, and other categories.

There are more than 500 records in the book. If the ground is so wet, water droplets will be like a flying wind, which will cause heavy rain; if the northwest wind dissipates, there will be no rain; when the sycamore flowers are born, red will be drought, and white will be water; and so on.

These records reveal from different aspects that some laws of weather and climate change are mostly scientific and accurate. They also quote a large number of exquisite proverbs, such as "Although the upper wind opens, the lower wind does not dissipate, and the main rain is the clouds in the direction of the upper wind."

Although it has dispersed, the clouds have not dissipated in the downwind direction, which indicates that it will rain. The movement of the clouds is used to illustrate the amplitude of the high-air flow. The method is clever and the conclusion is correct.

The greatest value of this book is to record the weather and systematically explain the formation of convective weather. It put forward the initial wind principle, which is believed that solar radiation makes the ground hot and the air flow rises, which is called wind. It also records sea breeze and land breeze

, typhoons and other weather averages, year and day poor calculation methods, atmospheric phenomena such as atmospheric light and images.

After copying a large number of ancient books, Mei Chun summarized and summarized a complete set of experiences related to air convection based on his predecessors and recorded them into a book.

He has not been idle in the past few days of floating in the sky, and his main job every day is to record.

This is also the first person to personally determine air convection throughout history.

After arriving in Xishan, Mei Chun was mainly responsible for technical guidance due to injuries and lack of mobility.
