Although Lu Ming was worried about this, he didn't have a great sense of crisis. Those who foresee the outbreak of the Sino-Japanese War mostly think that the war will start in the Northeast, because the main Japanese forces have 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 European powers. Even if wars are ignited everywhere, the Japanese will have scruples and dare not use force easily in Shanghai.

Lu Ming gradually became interested in the two friends in the Soviet Union, and his intuition told him that once a war breaks out between China and Japan, China and Russia will definitely form allies. On this point, both sides have common interests, not to mention the bearded Peter who has repeatedly offered to help him .

Lu Ming felt that he should hint his attitude to them in a way that can advance and retreat.

"By the way, do you know the ink formula for writing secret letters?" Lu Ming asked suddenly.

"Cryptography potions are only used by spies. Why do you ask this?"

The bearded Peter and Andre were a little stunned, they didn't know why Lu Ming asked this question.

"I have a special purpose, so you can just think of me as writing a letter to your lover." Lu Ming joked.

"Lu, you are asking the wrong person. We are all military advisers, not spies." The bearded Peter shrugged.

"I see that you are intimate with several girlfriends, and you don't shy away from it. How can you write secret letters?" Andre followed and drummed.

"Gentlemen, let me be honest. I'm not trying to test you, but I really want to ask you. I have a letter in my hand. I suspect it was written in secret writing. How can I make the secret writing appear?" What about it?" Lu Ming laughed.

Peter and Andre glanced at each other. If they hadn't figured out all about Lu Ming, they would have really suspected that Lu Ming was testing their identities.

Lu Ming is not an anti-espionage officer of the national government, and after several months of communication, this is absolutely certain.

In fact, Peter and Andre cannot be regarded as real spies. They are internal staff of the Soviet Military Intelligence Bureau, not spies who specialize in field work for intelligence.

They generally travel around the world as diplomats or other identities, develop intelligence personnel, or instigate spies from other countries for their own use. The purpose is to establish intelligence networks in areas where the Soviet Union needs to have intelligence.

Neither Peter nor Andre had full espionage training because they were not classified as espionage officers.

They really don't know the formula of the secret writing potion, and they have never used it. There are professionals in this field in the bureau to be responsible for the appearance of secret writing letters.

But they knew the basic principle of secret writing, so they told Lu Ming what they knew.

Peter laughed and said, "Lu, every spy has his own secret writing potion formula. There is no uniform standard in this regard, otherwise secret writing would be meaningless. Generally speaking, only specially formulated developing potions can It is not possible for any developing potion to make the secret writing appear."

Andrei then said: "Actually, there are various recipes for steganography potions. There are too many. I think that Comrade Lenin used the most primitive and special secret steganography in order to avoid the eyes and ears of the tsarist prison guards in the Siberian prison. Means, do you know what it is?"

Lu Ming shook his head blankly.

"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 bread as an ink bottle, used milk as ink, and wrote it in the blank space of the book. It's written." Andre laughed.

"Oh, that's okay too? Comrade Lenin is so brave!" Lu Ming also laughed.

"To tell you this story is to tell you that it is not necessary to use developing potion to reveal the handwriting. It can be achieved by roasting or steaming. It depends on the secret writing method used by the writer."

Peter and Andre seriously suspected that Lu Ming had intercepted a secret letter written by a Japanese spy. Otherwise, how could he not know the formula of the developer?

In fact, if there is no correct developer potion, it is useless to intercept this kind of encrypted letter, just like intercepting the enemy's telecommunication signal without knowing the password.

Lu Ming complained incessantly. He didn't know what secret writing method the elf Ziyuan used, but he stubbornly believed that he would be able to crack it. The problem was that he had never encountered such a thing as secret writing before.

If neither party is a spy, it may be better to write the letter in a code word or anagram that both parties can guess.

Lu Ming originally tried to unravel cryptic words or anagrams, and decipher Ziyuan's letter, but all failed.

He suddenly thought of secret writing potion. Yuan Ziyuan and Sheng Muyi are both proficient in photography techniques. 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, there are ready-made ones available in photo studios.

So he bought back developer and fixer, risked damage to the letter and soaked it in it, but he worked for a while, but still got nothing.

There was really no other way, so Lu Ming asked Peter and Andre for advice, that is, a dead horse is treated as a living horse doctor.

The two had a long joke and talked about it, and introduced various methods. In fact, it can be summed up in one sentence: no solution.

They just didn't want Lu Ming to misunderstand that they were hiding their secrets and refused to say anything, so that's why they said a lot of embellishments.

"Lu, if it's not urgent, you can give us the file, and we'll send it back to China, and ask our domestic experts to try it out, or they can crack it," Peter said.

"That's not necessary. It's not a particularly important thing. I just have nothing to crack and play." Lu Ming pretended to be relaxed and smiled.

Peter and Andre unabashedly sneered at Lu Ming, isn't it important?Liar.

It doesn't matter. You are desperately looking for a way to crack it. Isn't it good to drink and dance when you are free?It took me so long to ask for advice, I really have nowhere to go.

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 what Lu Ming held was really important information from the Japanese.

After Lu Ming went back, he was not in a hurry to try the various methods Peter said. Although Yuan Ziyuan's letter was not damaged after being soaked in the developing solution, it was not as strong as before.

You have to figure out which method is more reliable, and you can only try again.

While he was meditating, someone knocked on the door suddenly, opened the door, and Yan Xiaohui came.

Yan Xiaohui brought unprecedented good news, which instantly dispelled the haze in Lu Ming's heart.

"On New Year's Eve, the business community in the Japanese Concession will hold a Sino-Japanese Friendship Party. The leaders of Manchurian Railway will attend, and Seishiro Ozawa will also show up." Yan Xiaohui said a little excitedly.

"Great, the opportunity is here!" Lu Ming was so excited that he almost jumped up.

Ozawa, the shy turtle, is finally going to show his face. Although this day will come sooner or later, if it continues, his patience will soon be worn out.

Ozawa Seishiro was huddled in the Manchurian Railway Building in the Japanese Concession, Lu Mingzhen still had nothing to do with him, it was absolutely impossible to go into the Manchurian Railway Building to arrest people.

That is equivalent to going deep into the tiger's den to catch a tiger cub, and there is no other possibility except to automatically send someone to the door.

"This is the list of attendees from both China and Japan. They sent it to you right away." Yan Xiaohui said coquettishly, shaking the two pieces of paper in his hand.
