Chapter 153 John Rabe?

The preparation process is not complicated, mainly composed of nitration and purification, but one thing needs to be paid attention to, the toxicity of trinitrotoluene.

The King of Explosives is moderately toxic and can enter the human body through the respiratory system, digestive system and skin, causing toxic reactions in body parts such as the skin, liver, stomach, blood and eyes, and even death in severe cases.

In order to develop this king of explosives, which was born in 1863, Yu Hua specially made two sets of chemical protective suits by hand to protect himself and Xu Rui.

At this time, the research and development progress of the King of Explosives in the laboratory is coming to an end.

Yu Hua, who was wearing a chemical protective suit, wore a gas mask like a pig's nose. There were needle-like colorless crystals on the operating table. This was the king of high-purity explosives. Next to him was his old friend, Lei. Mercury acid.

The extremely stable king of explosives and the mercury fulminate used for detonation are an inseparable combination. Despite the research and development of trinitrotoluene, Yu Hua still managed the mercury fulminate.

Holding a pen in his right hand and a notebook in his left, Yu Hua silently recorded the last paragraph of the experiment.

In the notebook, the detailed refining steps of the King of Explosives, the third nitration step, the extraction process of raw materials, etc., and the production process of mercury fulminate are recorded.

Toluene, the core raw material of the king of explosives, mainly comes from oil, and the Eighth Route Army during the Anti-Japanese War originally owned the Yanchang Oilfield with a daily output of about 1.5 tons.

1.5 tons may not be much, but it definitely meets the production needs of the king of explosives.

In addition, in order to expand production in the future, Yu Hua also sent this notebook to Yumen Oilfield, which is based on the coordinates of an underground heavyweight oil producing area.

Precise coordinates: 15 meters north of Laojun Temple in Yumen.

Yumen Oilfield started in 1939 and was the only large oilfield in production during the Anti-Japanese War. Its oil production accounted for 90% of the total oil production during the Anti-Japanese War, reaching 25 tons.

The Eighth Route Army did not lack industrial blood and raw materials, but only industrial foundation and technology. Yu Hua could not satisfy the industrial foundation, but technology, not to mention satisfaction, at least had.

Next to him stood Xu Rui, who was also wearing a chemical protective suit, holding a small notebook and a pen in his right hand, recording what he had learned today.

A good memory is not as good as a bad writing.

After these days of study and experimentation, Xu Rui already has a wealth of experience in gunpowder preparation, and has mastered the preparation process of three gunpowder technologies. Now, he is learning the principles and basic knowledge of chemical reactions.

"Remember, the third nitrification is the most important. It belongs to a two-phase reaction, the reaction formula..." Yu Hua explained the basic chemical principles and nitrification reaction formula to Xu Rui while recording the detailed experimental steps in the last paragraph.

Xu Rui nodded again and again.

After about a few minutes, Yu Hua finished explaining the basic chemical principles and writing the experimental records. He put down the pen, glanced at the finished product, and said to Xu Rui, "Sharp words, organize the finished product, and keep it properly. How many experimental materials are left?"

"Sir, the experimental materials are basically gone. The remaining sulfuric acid and nitric acid can still make a single base medicine. If necessary, I will buy it immediately." Xu Rui heard this and gave the information like a treasure, and replied.

"No need, you can dispose of the remaining materials later, how much money do we have left now?" Yu Hua shook his head gently, changed the subject and asked for funds.

The completion of the research and development of trinitrotoluene gunpowder means that the entire gunpowder research and development plan has come to an end, and there is no need to waste funds to purchase chemical experimental materials.

Single-base charge, double-base charge and high explosive, including three gunpowder technologies with seven different styles of gunpowder formulations, suitable for almost all types of weapons, pistol, rifle, machine gun, mortar, large-caliber shells, Primers, grenades, mines, explosive packs...

The gunpowder research and development plan has come to an end, and the next thing Yu Hua has to do is to mail it to Lin Wan.

Xu Rui quickly gave the amount of the remaining funds and responded: "There are about a thousand oceans left. During this time, I spent a lot of money on guns and chemical materials. I will let Xiaoxue remember the detailed account expenses."

The entire chemical laboratory costs 250 yuan, plus the purchase of guns and subsequent purchases of expensive chemical experiment materials, such as materials such as neutralizers, plus various expenses, and the remaining funds are only [-] yuan about.

That's it, Yu Hua got the school's 300 yuan fiat bonus, and went to the black market to exchange for the ocean, and only one thousand.

Only a thousand.

Yu Hua pondered this number silently. One thousand oceans seems to be a lot. It is enough for Yu Hua and Xu Rui to live for many years, but if they are put on the next project, it is far from enough.

For a seven-tower device to produce sulfuric acid, the initial investment in research and development needs to be at least [-] oceans, and [-] oceans is far from enough.

Gotta get an investment.

Facing the predicament, Yu Hua already had the faces of the rich Zhou Yuan and the rich woman Fang Yu in his mind, as well as Lin Wan, who had become the representative of the Eighth Route Army in his heart. With his current relationship and popularity, it shouldn't be difficult to borrow some money, right? ...

It has to be said that Yu Hua's technology research and development process is actually unhealthy. He has only reached the link of producing results, lacking the most critical product sales link, unable to convert scientific research results into products, obtain profits, and then invest funds in the research and development link. , to form a healthy technology research and development ecological chain.

Without a healthy ecological chain, it is natural that sufficient funds cannot be obtained.

However, before the Japanese army was about to launch a war and the Second World War was approaching, Yu Hua could not open a company in China and establish an ecological chain of production and research.

Well, even if he opened a company, Yu Hua had to face not only the Japanese, but also those corrupt officials in the Republic of China.

And this also caused Yu Huakong to have the technology but no funds.

"I see, you are busy first." Yu Hua finished thinking, picked up the notebook recording the three gunpowder techniques, turned around and walked to the lounge.

Xu Rui suddenly asked aloud, "Sir, what should I do about the laboratory, does it need to be demolished?"

"The laboratory... keep it for now, these instruments and equipment are still useful." Yu Hua stopped, looked back at the small chemical laboratory that accompanied him for dozens of days and nights, and said after pondering.

"Okay." Xu Rui nodded when instructed.

Yu Hua came to the lounge, put on simple clothes, and carried a backpack with a pen handwritten version of "Gunpowder Technology" and "Barefoot Doctor's Manual". After leaving the laboratory, he went to the Dongcheng District Post Office.

It's Yu Hua's principle to shoot for a different place and not to send things twice from the same post office.

After a month of careful sculpting and careful review, it was confirmed that there were no quotations or the atmosphere of the times, and the pure version of the handwritten "Barefoot Doctor's Handbook" that condensed Yu Hua's painstaking efforts was finally released, with a total of 260 million words.

Handwriting 260 million words a month is only possible for Yu Hua. This is an epic book no less than "Mechanical Drawing". Yu Hua is not going to submit it to an academic journal, but is going to submit it to Xinhua News Agency for publication through Lin Wan. .

It's so important... so important that Yu Hua doesn't want to copy it a second time.

Damn it, this thing is more than 200 million words in one copy. In order to ensure that the original manuscript can be printed, Yu Hua did not hesitate to use the relationship he had accumulated with the Eighth Route Army.

Yu Hua believed that with the help of the red secret deciphering materials and mechanical drawing, he should have accumulated a considerable degree of popularity on the eighth road. This is a friendship and a popularity.

Other newspapers and magazines may not print the Barefoot Doctor's Handbook, but Xinhua definitely does!
The sun is shining and the weather is hot.

After exiting the narrow and quiet alley, we came to the bustling and bustling Xishiku Street. There were many people on the street, and all kinds of shouts were constantly being heard. Yu Hua, wearing a gray long gown, walked unhurriedly on the right side of the street, with a straight back and steady steps. powerful.

Seeing Yu Hua with such a demeanor, many pedestrians subconsciously gave way, and a sense of respect was born in their hearts.

With a poetic and literary spirit in his belly, Yu Hua already has a faint scholarly temperament.

Elegant and confident.

Even wearing a cheap long gown, that kind of temperament is indelible.

There are two post offices in Dongcheng District, one north and one south. The closest one is Dongcheng North Office. Go south along Xishiku Street, pass Xishiku Church, and come to the fork. Yu Hua turns left and goes to Jingshan Park. go.

Jingshan is the coal mountain where the late Ming emperor Zhu Youjian Chongzhen was hanged.

After passing through Jingshan Front Street between Jingshan Park and the Forbidden City, and after a short walk, you will arrive at the Dongcheng North Bureau.

As we came to the vicinity of Jingshan, a long and rich historical atmosphere rushed towards us, and the stretch of palaces came into view. The magnificent and magnificent Forbidden City was filled with the supreme imperial power.

Looking at the Forbidden City in 1937 in the distance, and staring at the most magnificent and tallest building in Peiping City, Yu Hua couldn't help but stop and stay silent.

This is the second time he has seen the Forbidden City with his own eyes.

The first time was the 2019th anniversary military parade in [-]. At that time, the Forbidden City was majestic and magnificent, with bright red everywhere, exuding an indescribable surging atmosphere, like a man who had just come of age, full of vigor.

The current Forbidden City, although unchanged, is still grand and tall, but it has an air of dilapidation.

One is the scorching sun, and the other is the pearl of rice. The two are the same, but they cannot be compared.

"In a short while, I will be a slave to the subjugation of the country..." Yu Hua quietly looked at the Forbidden City, and said this sentence slowly for a long time.

"Yu Hua?" At this moment, a magnetic male voice came, not in Chinese, but in German.

Hearing the shouting, Yu Hua was a little puzzled. He recovered and turned his head to see that it was John Davis, Mr. Physics, wearing a suit with a briefcase in his hand. There was another unknown person standing beside him. foreigners.

"Hello, Mr. Davis, why are you here?" Yu Hua saw Davis, a little puzzled, and quickly stepped forward to say hello, with a fluent and standard Berlin accent.

Davies was overjoyed when he heard this pleasant Berlin accent, smiled and joked: "That's exactly what I want to ask, why are you here? You know, the day after tomorrow is full of The city entrance examination, and as the number one in the school, you are not in the school."

It has to be said that the reason why Davis allowed Yu Hua to study by himself is inseparable from his fluent and standard Berlin accent.

This is the first time he has been able to communicate without barriers for so many years in China.

"Sorry, Mr. Davis, I will definitely go back to school immediately after I'm done." Yu Hua responded.

"Okay, Yu Hua, I'm joking."

Davies continued smiling and said to Yu Hua, "I'm here to meet a friend and let me introduce to you. This is John Rabe, the representative of Siemens in China. He is my good friend. The student you mentioned, Yu Hua. I asked him to give him a German name, but he rejected him, hahaha, he is the most talented and brightest student I have ever met, no one, if you want to say how smart he is , I think he is no less than Einstein in his boyhood."

Who?
Regarding the words of Mr. Physicist Davis, Yu Hua was stunned in place, and some did not respond. The reason was not from his compliments, but from the people he introduced...

John Rabe!

This is an unknown foreign name, but his name is worth remembering by every Chinese, and Yu Hua wrote it down.

His eyes involuntarily fell on the bespectacled German next to him, and when he looked at it, a hint of respect appeared in his eyes.
