Lin Wan, I am Zhang San. Zhang San leaked one of the top secrets of the Blue Clothes Club to you last time. I am very happy that I am still alive when I write this letter.
Because this means that you successfully received the complete red secret deciphering information and did not leak the information.
Thank you, you lived up to my expectations and allowed me to live peacefully without being captured and tortured by the Japanese to challenge my weaknesses.
I have not undergone strict spy training and cannot withstand the torture of those cruel torture instruments. I will definitely leak the secret. So if one day I am caught, I will try my best to commit suicide. Please don't waste the power of the organization to save me.
Okay, let’s get back to the topic, classmate Lin Wan, please read the following content while ensuring safety. If possible, please read it under the protection of the organization. The notebook contains scientific and technical information carefully researched by me.
It is extremely important to the organization, please keep it properly.
If you are indeed classmate Lin Wan.
Please solve the second question.
——Zhang San.
"Jin Yu will definitely not put you in danger..."
After reading the content written on the first letter, a feeling of trust came to her heart. Lin Wan was extremely moved. She whispered to herself, calmed down her mind, adjusted her state, and turned to look at the professor and secretary sitting next to her.
The chief said in a serious voice: "Chief, what Mr. Zhang San sent this time is scientific and technical information."
"Please continue, Qingluan." Upon hearing this, Comrade Professor's face became more solemn.
The secretary-general sitting next to him holds a pen in his right hand, recording information.
Lin Wan, who was in a safe environment, immediately put down the first letter and answered the math questions given on the first letter. This question was more difficult than the previous question. She carefully reviewed the questions and looked for ideas to solve the problems.
.
According to common sense, this kind of problem-solving process will generally be handled by personnel with sufficient knowledge to save time as much as possible. However, Zhang San’s identity is too important and belongs to the highest level of top secret. In order to reduce the risk of leakage as much as possible, no
Let other people solve the problem.
Time passed minute by minute. About ten minutes later, Lin Wan, who had improved her mathematics level through the practice of problem-solving tactics, had a layer of sweat on her forehead. The proof paper was full of proof processes, and she slowly wrote a number with a pencil——
77.
After confirming three times that the answer was correct, Lin Wan was familiar with the task. She immediately opened page 77 of the arithmetic problem book and found the second piece of paper between pages 77 and 78.
The professor and the secretary-general were all attentive, staring at Lin Wan who was receiving the letter. They waited quietly and attached great importance to the scientific and technical information described by Mr. Zhang San.
What is scientific and technical information?
How much help will this scientific and technical information, which Mr. Zhang San has high hopes for, bring to the organization?
One question after another came one after another, appearing in the minds of the two professors.
Lin Wan could clearly feel the serious and depressing atmosphere in the conference room. She took out the letter and paused for a moment to prepare herself mentally. Then, under the gaze of the professor and the secretary-general, she slowly opened the second letter.
Hello, Lin Wan, and other organizational leaders.
Do you still remember the red secret deciphering information?
Without further ado, let’s get straight to the point.
If my guess now is correct, according to the red secret deciphering information, you should have a complete understanding of the movements and situation of the Japanese army, and understand that Japan is about to launch the Greater East Asia War, and is actively preparing and responding to it.
Regarding the Greater East Asia War, this is a war that can never be avoided, a war that cannot be stopped. It is a crisis of national subjugation that China and the Chinese nation must face. It has been upgraded from a local anti-Japanese war to a comprehensive anti-Japanese war.
If this all-out war of resistance is defeated, China will perish, and there will no longer be China and the Chinese nation in the world.
We must gather the strength of the whole country to resist aggression and unite as one. Only in this way can we win this war.
However, due to the Long March and the Encirclement and Suppression, the strength of the organization and the Anti-Japanese Red Army has not yet been fully restored. The weapons level is mostly light firepower, and the most important military manufacturing capability has been lost, so small that it cannot make a bullet by itself.
As a result, its own strength will be severely limited. Facing the Japanese army armed to the teeth, the Anti-Japanese Red Army will be at a great disadvantage. To solve this problem, you must establish your own heavy industry and military industry and achieve independence.
Produce and manufacture weapons.
Of course, talking about independent production and manufacturing of weapons is not in line with the actual situation. The entire process is extremely complicated and needs to be supported by dozens of industrial categories, large and small. And in a short period of time, without equipment and technology, it is impossible for you to build a complete
Heavy industry and military industry.
There are many questions, so we solve the easiest ones first.
The scientific and technical information recorded in the notebook mainly involves the field of gunpowder and is used to solve the power problem of weapons.
The entire gunpowder technical information contains three mainstream gunpowder technologies, consisting of single-base propellant, double-base propellant and trinitrotoluene explosive. The three gunpowder technologies are subdivided into more than a dozen model formulas, which can meet the requirements of all military weapons.
Gunpowder requirements.
All types of gunpowder formulas have detailed production steps and processes, which are divided into simple versions and industrial versions. I have also written down the channels and sources for obtaining various chemical raw materials.
With this gunpowder technical information, you will establish your own explosives industry and produce gunpowder that meets the needs of military weapons. I believe that when grenades filled with black powder and grenades filled with trinitrotoluene are placed in front of you, you will choose.
who.
The explosives industry requires a certain level of basic chemical engineering, and among the 'three acids and two alkali' of traditional chemical industry, the sulfuric acid industry is the most important. Before the Japanese officially launch the war, you still have a precious time to purchase equipment.
Come and establish your own sulfuric acid industry.
With the sulfuric acid industry, there will be no obstacles to the explosives industry. With the explosives industry, and the establishment of the steel industry and precision machinery industry, we can achieve independent production and manufacturing of weapons.
Pay special attention to the fact that toluene, the most important raw material of trinitrotoluene, mainly comes from petroleum. You have the Yanchang Oilfield in Yanchang, which can meet the early demand for explosives production. If the demand for explosives increases, you can go to Yumen Laojun Temple and beyond.
Drilling for oil fifteen meters to the north. This place was explored by my teacher before. It contains rich oil resources. Preliminary proven recoverable reserves amount to 20 million tons of oil. It is estimated that the annual oil production can reach more than 500,000 tons.
My teacher has not announced this oil field to the outside world. Only I know it, and now I will officially inform you.
Lin Wan, if you are the only one reading this letter, please protect it with your life and hand it over to the organization as soon as possible. Never leak the information.
Because the recoverable reserves of this oil field were enough to make the Japanese army, which was short of oil, change its strategic offensive plan and target northern Shaanxi.
As soon as possible, keep it secret. The confidentiality measures of the notebook are the same as those of the red secret deciphering information.
Protect this information, be sure to protect it!
In my mind, in terms of importance, this technical information is much more important than the red secret deciphering information.
Finally, Lin Wan, please help me tell the organization that the red flag of China is the real hope of China, and this is the reason why I am willing to help you.
The red flag originated from the October Revolution, and the red flag of China was born on July 23. You have gone through many hardships and have noble qualities and tenacity that other Chinese organizations do not have. Please continue.
Work hard for the future of China and the future of the nation.
——April 29, 1937, Zhang San.
"An oil field with recoverable reserves of 20 million tons!"
Lin Wan's right hand was trembling slightly. After reading the second letter, a look of shock appeared on her face, her eyes were full of disbelief, and she could hardly suppress her inner emotions.
There is no way, the information given by Mr. Zhang San in this letter is really shocking.
It can build complete gunpowder technical data for an explosives industry, plans for the future industrial development of the base area, and finally the super aniseed waiting for her - an oil field with recoverable reserves of 20 million tons!
Lin Wan knew exactly what this oil field in Yumen meant. If the news leaked out, attention from all over the country would be attracted to the Yumen Oil Field.
Because, before this, China still wore the label of being "poor" on its head, and there was almost no oil field in the country with recoverable reserves of tens of millions of tons.
Well, not to mention the 10-million-ton level, not even the 5-million-ton level.
PetroChina basically relies on imports, and its self-produced oil is pitiful and the quantity is almost negligible.
"Qingluan, what did Mr. Zhang San say in the letter?" Seeing the shocked expression on Lin Wan's face, Comrade Professor asked with doubts and a serious face.
Lin Wan came back to her senses, looked at Liu Wei, glanced at the secretary-general who was sitting next to him and was responsible for recording information, and said seriously: "Chief, the content of this letter can only be read by you, the secretary-general has no right to know."
The matter in the Yumen Oilfield was so important and critical that Lin Wan could hardly imagine it. If it were leaked, the consequences would be catastrophic.
