Although Lu Ming was worried about this, he didn't have much sense of crisis. Anyone who foresees the outbreak of the Sino-Japanese war mostly believes that the war will start in the Northeast, because Japan's main power has been entrenched there for more than 20 years.
The Northeast is too far away from Shanghai, two thousand kilometers, and Shanghai is the sphere of influence of the European powers. Even if war breaks out everywhere, the Japanese will have some scruples and dare not use force easily in Shanghai.
Lu Ming gradually became interested in his two friends from the Soviet Union. His intuition told him that once a war broke out between China and Japan, China and Russia would definitely form an alliance. At this point, both sides had common interests, not to mention that the bearded Peter had repeatedly taken the initiative to help him.
.
Lu Ming felt that he should give them a hint of his attitude in a way that allowed him to advance and retreat.
"By the way, do you know the ink formula for secret letters?" Lu Ming suddenly asked.
"Only spies can use steganographic potions. Why do you ask?"
Bearded Peter and Andre were both a little stunned. They didn't know why Lu Ming asked this question.
"I have a special purpose, so just think of me as writing letters to my lover." Lu Ming joked.
"Lu, you are asking the wrong person. We are all military consultants, not spies." Bearded Peter shrugged and said.
"I see that you are very close to several girlfriends and don't shy away from them. How can you write secret letters?" Andre followed suit.
"Gentlemen, I'd better tell the truth. I'm not testing you, but I really want something from you. I have a letter in my hand. I suspect it was written in secret. How can I make the secret handwriting appear?
What?" Lu Ming laughed.
Peter and Andre looked at each other. If they hadn't figured out everything about Lu Ming, they would have really suspected that Lu Ming was testing their identities.
Lu Ming is not a counter-intelligence agent of the Nationalist Government. After several months of dealing with him, this is absolutely certain.
In fact, Peter and Andrei cannot be regarded as real spies. They are internal staff of the Soviet Military Intelligence Agency, not spies who specialize in field intelligence.
They generally travel around the world as diplomats or other identities, developing intelligence personnel, or inciting spies to rebel against other countries for their own purposes, with the purpose of establishing intelligence networks in areas where the Soviet Union needs to master intelligence.
Neither Peter nor Andrei had complete espionage training because they were not classified as espionage officers.
They really don't know the formula of the steganographic potion, and they have never used it. The bureau has professionals in this field who are responsible for revealing the steganographic letters.
But they knew the basic principles of secret writing, so they told Lu Ming what they knew.
Peter smiled and said: "Lu, every spy has his own recipe for steganography potion. There is no unified standard in this regard, otherwise steganography would be meaningless. Generally speaking, only specially prepared developing potion can
To make the cryptic handwriting appear, no developing potion can work."
Andre continued: "Actually, there are many different recipes for steganographic potions. There are too many. I think that when Comrade Lenin was in the prison in exile in Siberia, in order to avoid the eyes and ears of the Tsarist prison guards, he used the most original and special steganographic potion.
Means, do you know what it is?"
Lu Ming shook his head with a confused expression.
"It's milk. Haha." Andre laughed.
"Milk?" Lu Ming still couldn't figure out how milk could be used as a secret writing tool.
"Yes, Comrade Lenin dug a hole in the bread and used it as an inkwell, and used milk as the ink, and wrote in the blank spaces of the books. After the books were sent out, the recipients would bake the paper with a fire, and it would show
The handwriting is gone." Andre said with a smile.
"Oh, that's okay? Comrade Lenin is so bold as a master of art." Lu Ming also laughed.
"I tell you this story to tell you that it is not necessary to use developing liquid to reveal handwriting. You can use fire or steam to achieve the development effect. It depends on the secret writing method used by the writer."
Peter and Andre seriously suspected that Lu Ming had intercepted a secret letter from a Japanese spy. Otherwise, how could he not know the formula of the developer?
In fact, without the correct developing potion, intercepting this kind of secret letter is useless, just like intercepting the enemy's telecommunications signal without knowing the password.
Lu Ming was complaining in his heart. He didn't know what secret writing method the weird Ziyuan used, but he stubbornly believed that he would be able to crack it. The problem was that he had never encountered such a secret writing method before.
If neither party is a spy, it is better to write a letter in a code word or anagram that both parties can guess.
Lu Ming originally tried to decipher argots or anagrams and decipher Ziyuan's letters, but all failed.
He suddenly thought of the secret writing potion. Yuan Ziyuan and Sheng Muyi are both proficient in photography technology. Will they use this method to secret write?
Although he is not proficient in photography, he can still make general developing and fixing potions. Even if he doesn't make them, they can be purchased ready-made in photo studios.
So he bought back the developer and fixer, and put the letters in to soak at the risk of damage. As a result, he worked in vain for a while, but still got nothing.
There was really no other way, so Lu Ming asked Peter and Andre for advice, which was to treat a dead horse as a living horse doctor.
The two made a lot of jokes and introduced various methods. In fact, it boiled down to one sentence: No solution.
They just didn't want Lu Ming to misunderstand that they were hiding their secrets and refused to tell them, so they said a lot of things in a sarcastic way.
"Lu, if this matter is not urgent, you can give us the document and we will send it back to China and ask our domestic experts to try it or crack it," Peter said.
"That's not necessary. It's not a particularly important thing. I'm just cracking the code for fun." Lu Ming pretended to smile casually.
Peter and Andre smiled disdainfully at Lu Ming. It's not important. He's a liar.
It doesn't matter. You are desperately trying to find a way to solve it. Isn't it better to drink and dance when you have nothing to do? I have been holding back for so long before asking for advice. There is really no way out.
The two of them didn't insist, and it was useless to insist. If Lu Ming didn't give it to them, they wouldn't be able to grab it. Besides, they couldn't be sure that Lu Ming really had important information about the Japanese.
After Lu Ming returned, he was not in a hurry to try the various methods Peter mentioned. Although Yuan Ziyuan's letter was not damaged after being soaked in the developer, it was not as strong as before. I was afraid that he could not help but use potions to destroy it in turn.
You must figure out which method is more reliable, and you can only try again.
While he was deep in thought, someone suddenly knocked on the door. When he opened the door, Yan Xiaohui came.
Yan Xiaohui brought unprecedented good news, which suddenly dispelled the gloom in Lu Ming's heart.
"On New Year's Eve, the business community in the Japanese Concession will hold a Sino-Japanese social gathering. The leaders of Manchuria Railway will attend, and Seishiro Ozawa will also make an appearance." Yan Xiaohui said with some excitement.
"Great, the opportunity has come!" Lu Ming was so excited that he almost jumped up.
Ozawa, the shy turtle, is finally going to show up. Although this day will come sooner or later, if it continues, his patience will soon be worn out.
Ozawa Seishiro was huddled in the Mantetsu Building in the Japanese Concession. Lu Ming really had no way to deal with him. It was absolutely impossible to enter the Mantetsu Building to arrest anyone.
That is equivalent to going deep into the tiger's den to catch a tiger cub. There is no other possibility except to automatically send it to the door.
"This is the list of attendees from both China and Japan. I sent it to you as soon as possible." Yan Xiaohui shook the two pieces of paper in his hand and said coquettishly.
