Back to the Republic of China to be a editor

"Is steelmaking enough? Not enough. Some parts of the tank can be made of ordinary steel, but the most important and critical parts are made of special steel." Tang Hua added smelting after molybdenum ore, and then pulled the arrow; Add smelting after the mine, and then pull the arrow; plus steel, a total of three arrows are gathered together.

"Here it should be written: Cannon Steel."

"The cannon steel is solved, but there is still armor steel. Everyone should know that special steel is not a kind of steel, but a collective name for many kinds of steel with different uses." Tang Hua continued to draw a line, adding a line to the manganese ore , is also the convergence of several arrows, "This is armor steel."

"Next, there's spring steel..."

"One, two, three, four, five, six, six kinds of special steel! Next, let's study copper and copper alloys, which copper alloys are needed for tanks..."

……

In the end, the blackboard was filled with Tang Hua's drawings.

Throwing down the chalk and clapping his hands, Tang Hua looked at the thoughtful audience.

"What you see are lines and squares. In fact, they all represent factories. This is a mine, an iron furnace, a blast furnace, an electric furnace... Separated from here, the car body frame, water tank, driving wheel, transmission Box, planetary steering gear, anti-aircraft machine gun mount, hydraulic buffer, oil-water radiator, torsion shaft... together, we just completed the chassis of the tank."

"The weapon industry is a special industrial production sector, and behind it is almost the entire country's heavy industry system. If this industrial system lacks one or two categories, then some of our weapons and equipment may not be able to be produced domestically. If we are not satisfied with manufacturing tanks, but want to independently develop and design tanks, armored vehicles, or other weapons, then we need to establish scientific research institutions, engineering design institutions, testing and testing facilities, deploy technicians, and allocate materials. We will gradually realize independent research and development from parts to complete vehicles."

"Today, everyone sitting here has designed a tank. In the future, you may not be the designer of the tank, but just take on one of the chains in the entire industrial system of tank development and manufacturing, or even a smaller job. .But even if it is a screw, it is making its own contribution to a strong military industry and a strong country.”

Chapter 19, Marching Northeast

"This is the end of today's class. Future designers of tanks, vehicles, engines, transmissions, artillery, electromechanical, optical instruments... from the next class, we will enter the course of guided weapons and ground equipment .”

On the podium, Tang Hua ended today's lecture, but it seems that many students in the audience did not get up and leave.

"Teacher Tang..." a student said, "The school notified us today that we are going to move."

"Oh..." Tang Hua understood.

The central government had predicted that the future situation in northern Shaanxi would be very difficult since the civil war was about to break out. Now it is late May, and it is almost time to start action.The Military Commission and the Central Committee are the command organizations, and the personnel are all soldiers. It is not a big problem to form a column to play hide-and-seek with the national army in northern Shaanxi.However, in addition to the party, government and army in Yan'an, there are also non-military institutions of science, education, culture and health like Yan'an University.By 5, there were still many scientific and cultural figures who defected to Yan'an.Before the outbreak of war, these institutions, personnel and necessary items were to be transferred in batches.

"Where is your school planning to move to, the Soviet Union, Jinchaji or the Northeast?"

"The school announced that it will be transferred to the Northeast," the student said. "After the victory of the Anti-Japanese War last year, some teachers and students in our school joined the Eighth Route Army and went out to the Northeast with the army. Now the whole school will be fully dispersed and transferred. The school will start tomorrow." Pack materials and supplies, the Academy of Natural Sciences part will leave on June 6, and the Luyi part will leave on June 15."

"This is a good thing," Tang Hua stepped down from the podium and sat down on a stool next to the students. "In Shanxi, Chahar and Hebei, and in the Northeast, our army has now gained relatively stable revolutionary bases. The superiors should inform you. In the past month, our army has conquered Changchun, Jilin, and Harbin. Although the overall situation in the country is still strong and we are weak, it is not the most difficult time. After you arrive in the Northeast, your first task may not be to study. Instead, it is to participate in the restoration of industrial production and provide weapons and equipment support for our army. This is also a rare internship."

"Teacher Tang, it would be great if you went to the Northeast with us."

Tang Hua fell into deep thought. "To be honest... I really want to go. You may not know that the Northeast is the region with the most industrial facilities and the highest industrial output value in China. From the period of Zhang Zuolin to the period of Japanese occupation, the industry in the Northeast, especially the heavy industry, The speed of development has been very fast. Although Shenyang is occupied by the Kuomintang, cities such as Harbin, Qiqihar, Jilin, and Changchun have a lot of heavy industries. If we can firmly occupy parts of the Northeast, our army can even partly get rid of relying on The situation of seizing weapons and ammunition for combat. However, if war breaks out, the most difficult areas will still be in the pass, especially the Shaanxi-Gansu-Ningxia Border Region, and this is where the Central Committee is located. There is no room for loss. Teacher Tang will stay here. Thousands of miles apart, but remember, we are all doing the same thing, which is to liberate all of China."

Some of the students nodded, some looked around, but none of them seemed to speak.

"I know, this lesson may take a long time to finish. But don't worry, I will teach you until the day before you leave." Tang Hua knew what they were thinking, "Remember, the northeast is very cold, and winter is colder than Shaanxi. It is very cold in the north, so remember to wear thicker clothes... Also, I will assign homework for you. This homework is not written in the homework book, but for you to complete it in practice. When the whole country is liberated, we will Get together, and Teacher Tang will check your homework again."

……

Walking on the campus of Yan'an University, Tang Hua found that something was really different.Some reference rooms and laboratories have been closed, and teachers and students have begun to pack books and experimental instruments.The student dormitory is still quiet, but soldiers have begun to move into the dormitory. It should be that the Shaanxi-Gansu-Ningxia Border Region has recently begun to expand its troops.

"Chairman! Commander-in-Chief! Vice-Chairman Liu!...and Commander Ye, are you all here?"

Tang Hua strolled around the campus after class, went to Luyi to tinker for a while, then ate in the cafeteria, and returned to the place where he lived after dark.Before entering the door, the chairman and his party had already arrived, and the four of them were walking around the front yard of the cave dwelling.

"Oh, Xiao Tang," said the chairman, "it's been too busy for a while, and we haven't attended your lectures for a long time. As of today, the matter has come to an end, so I just came to you for a chat."

"The chiefs should have been quite nervous some time ago," Tang Hua said. "There are big things happening in the Northeast and the Central Plains. Every decision now is critical."

……

"I just said, this kid from Guangdong knows everything." The commander-in-chief broke the silence.

Tang Hua smiled, "I do some analysis of the military situation from public and semi-public information channels. If these analyzes can provide references for the chiefs to make decisions, that would be the best. It's just intelligence and information from my side. , if it can be analyzed, compared and judged together with your ministry's intelligence system, then the conclusions obtained should be more accurate.",

Chairman: "Our intelligence is actually not that mysterious. I have talked with Shaoqi and the commander-in-chief before. The process and channels of obtaining intelligence may need to be kept secret, but the intelligence itself is fine to tell you. Put all The known information is put together, and you have the bottom of your heart.”

Commander-in-Chief: "What is Chiang Kai-shek going to do with the troops of the Central Plains Military Region next, Tang Hua, what's your judgment?"

Tang Hua nodded, "Let me start from the beginning and speak slowly. I will bring the source of the news to every step of my deduction."

"First of all, Tang Enbo will resign, and Li Mo'an will take over his position as commander-in-chief of the Third Front Army."

Tang Hua took out newspaper clippings from early May, "In the newspapers at the end of April, I saw the news that these factories had been relocated or auctioned off. These were all when Tang Enbo was the commander-in-chief of the Third Front Army. He is now going to auction off the profitable business done in the region, which means that he is about to change the place to do business. On this newspaper is the report of the reporter interviewing Li Moan. Look, this sentence, and the meaning implied by this sentence It is clear."

"Li Moan is a first-year student in Whampoa, and a member of Chen Cheng's system. After Chen Cheng became the chief of staff, Tang Enbo and Chen Cheng have been in conflict. Of course, Tang Enbo cannot leverage Chen Cheng. It should be natural for him to resign. After that, he will be Chen Cheng's hardcore. Li Moan took over as the third Commander-in-Chief of the Front Army. Next is Liu Zhi's movements... In fact, there are more information in this report, which completely spoils the movements of Liu Zhi's subordinates. In general, the plans of the top military officials or Chiang Kai-shek That is, Li Moan attacked Shandong, and Liu Zhi's troops attacked the Central Plains Military Region. Li Moan is very smart. On the contrary, Liu Zhi is not a person who is particularly capable of fighting, but the existing strength of the Central Plains Military Region may be too weak."

"Oh?" Vice Chairman Liu said, "We have confirmed before that the national army is about to launch a large-scale offensive. The time is about early July, and we... can get the national army's combat plan in advance. The personnel changes of the national army However, there is no conclusive news yet... If Li Mo'an replaces Tang Enbo, then Shandong needs to pay attention."

Li Mo'an does not appear in most war film and television dramas in our country, so he does not leave a deep impression on people.But he did not appear in the film and television drama because he was neither arrested nor wiped out.Li Mo'an has a very high IQ and is extremely shrewd in his work.When I was at the Whampoa Military Academy, I was the first to join the party and the first to quit.During the Anti-Japanese War, I fought in the Battle of Xinkou, and then went to be the commander of an empty shell army, and paddled easily for 8 years.During the War of Liberation, the three fields were not strong at the beginning, so he fought in Shandong. When Su Yu and the others started to become stronger, Li Moan withdrew from the front line of command and became the chairman of Hunan Province. The uprising in 1949, also known as the dislike of General Mosaic, went abroad after the uprising was electrified.Guess where he went abroad?Argentina (the Kuomintang cannot reach there) provides for the elderly.Then, when he returned to China in 1980, with his signature on the telegram of the uprising, he became the stomach of the CPPCC for two consecutive terms...

"This is a newspaper from Wuhan. If you read the reports here, you can see that the railways and waterways are heavily controlled by the military. From this, you can roughly infer the size of the troops deployed by the Chinese military..."

"The next day's newspaper still has this content. I think this is a very bad signal. Our negotiators should pay more attention to it, and be careful not to be torn up by the Kuomintang... Yan'an's information channels are not as good as Shanghai Lingtong. If the newspaper can arrive sooner Some, if you can find newspapers in some small cities, you may get more information.”

In Tang Hua's hand was a thick newspaper clipping, and there was also a complete stack of newspapers, which were opened one by one to analyze the movements of the national army.

"Don't believe in the "Hankou Agreement." Vice Chairman Liu said, "We cannot let this agreement tie our hands and feet. A little hesitation will cause tens of thousands of losses."

Tang Hua nodded in agreement. "If the situation in the Northeast is like Liu Bei's entry into Shu, then the current situation in the Central Plains Military Region is more like the fourth or fifth campaign against encirclement and suppression."

Chapter 20, jokes, not three wears

"Chief, what you want."

"Thank you, Comrade Xiao Xu."

At the entrance of the cave, the guard handed over a package of things that Tang Hua wanted, saluted, turned and left.

"Now I'm going to start using long-lost traditional DIY skills..." Tang Hua said to himself in the cave.

There was a small iron bucket with a lid on the table, which contained most of the well water that Tang Hua had brought up from the well.

Open the package that the guard gave him, and lay out the contents one by one.

A packet of sugar, a packet of caramel, a small packet of baking soda, a few limes...

That's right, the Coke that Tang Hua brought with him when he set off from Shanghai has all turned into empty glass bottles piled up in the corner of the room, and now they are broken.

I had no choice but to make my own Coca-Cola.

Put the caramel into the well water first and stir.When the color was about the same, Tang Hua began to pour sugar into the water.

When the sweetness is right, open the baking soda, pour a part into it, and stir gently with a long-handled spoon.

After stirring evenly, small blisters can be seen in the water in the iron bucket.

Then Tang Hua started to squeeze the lemons. After squeezing three or four lemons, the water in the bucket finally tasted sweet and sour.
