Liu Yuexin quickly turned around and saw a silhouette in the alley. The person was almost back to her. Could this be the person who passed the note? She was a little excited.
Just as she got into the car, there was a note in a crack in the car. It was difficult for the driver to see this position, but it was easy for the people sitting in the carriage to notice.
She had already received ten similar notes. These notes were very strange. Sometimes they were in her pocket, sometimes in her bag, sometimes in her shoes, sometimes in her open lunch box, and sometimes even on her door. This time, they were in her rickshaw. It was as if that person was always by her side.
And she didn't know who that person was?
Because the note had said not to do anything to probe him. It was very dangerous for both of them.
At the end of each note, there would be an interesting instruction, such as: If you agree, then I want to see you wearing that orchid cheongsam tomorrow. If you think I'm right, you'll be wearing that pink lipstick of yours tomorrow, and if you can understand, then let that pretty enameled hairpin do the talking. He seemed to be very familiar with her, almost remembering everything she had worn before.
Every time, she would choose a positive answer and follow the instructions to dress herself up. She knew that that person would admire him from somewhere. Even if he was Japanese, she could tell that he was anti-Japanese!
Just like that, they communicated in a special way.
Of course, the note would be burned, and every time she had to look it up in the German dictionary because the note was in German.
Actually, she had thought that he was Japanese because of his German.
That person was afraid that she wouldn't understand Japanese, and that person didn't know Chinese, so he chose to communicate in German. In fact, that person knew almost everything about her, so how could he not know that she knew Japanese? Safety, of course, must be considered from the perspective of safety.
Until one day, she found a booklet at her door and a note he had left for her, proving that her guess was true.
It was no longer a note, but a very long letter.
After reading the letter, she almost lost sleep. She burned the letter and placed the booklet in an extremely difficult place. It was a bamboo tube. He rolled up the booklet and stuffed it into the bamboo tube. Then, he placed the bamboo tube and a pile of bamboo tubes on the pile of firewood.
Because the first page of the booklet said: A leaf could only be hidden in the forest so that it would not be found!
The last page of the booklet was the rules of Morse code and the 300-digit pi. He asked her to recite the pi from 213 digits to 105 digits.
Her heart trembled. She felt her heart melt because February 13th was her birthday. Then would January 7th be that person's birthday?
On the second day after receiving the letter, she did not dress up according to the instructions. She thought of many things, even if she was filled with some kind of emotion now.
However, even though she had expected the consequences, she was still like a moth. She knew that it was an abyss, but she could not escape the temptation of light. If only she was an orphan! She would leave with him without hesitation! Even if he lost his life.
She had returned to Shanghai from Peiping to avoid the war. There were no boys in their family, and she was the only parent. She had her own reasons for choosing Japanese. She knew that as a weak woman, she might be able to use this skill to contribute to this weak country in the future.
Her classmates went to the streets to protest, but she didn't go. Her classmates went to the 29th Army to express their condolences, but she didn't go. It wasn't that she didn't want to go, but she was waiting for another opportunity.
Before she left, she received a recommendation letter from her Japanese teacher, Teng Suyi.
It was that recommendation letter that allowed her to successfully enter the telephone traffic class! This was because there was an even more important department, the Teleportation Department, after the telephone traffic department.
That day, she didn't dress up as the letter said. She didn't go to the cafeteria at noon either. Her eyes were red and she felt dizzy. Sister Sun helped her get food. The class monitor arranged for her to get off work early and go home.
——————
That person probably didn't see her that day.
When he returned home, his father, who was teaching at the university, had nothing to do at home because the university had been destroyed in the war. Although the family had savings, they still wanted to find a job.
He had already received a few invitation letters from universities in the mainland. The exiled Fudan University in Shanghai, Great Xia University in Shanghai, Tongji University in Shanghai…There was a serious shortage of professors.
As a professor whose school had been destroyed in the war, he naturally hated the Japanese and wanted to go to the mainland. However, the journey was long and the flames of war were endless. It was easier said than done for a family.
Therefore, Mr. Liu was at his wit's end at home. When he saw his daughter return, his expression was ugly.
"Why are you back so early?" Mr. Liu's tone was clearly unfriendly.
Mrs. Liu's heart ached for her daughter. Last night, she saw that the lights in her daughter's room had been on until very late. Perhaps her daughter had grown up and had something on her mind.
She rolled her eyes at Mr. Liu, held her daughter's hand, and said gently,""Little Xin, let's go to your room."
"No, Mom, I want to talk to Dad!”
The Liu family's parents were stunned.
"Dad, can you take Mom away from Shanghai? Didn't Uncle Su from Fudan University send you a letter asking you to go to Changsha?”
"What's wrong? What do you want? You must tell me!"
"Mom, don't come over. Dad, please come with me.”
Mrs. Liu wanted to follow her, but Mr. Liu stopped her with his eyes. He knew that this girl had been careful since she was young. She chose to study in Beiping instead of staying in Shanghai and hid under her parents 'wings. Mr. Liu admired her a little. Unfortunately, she was still a girl. If she was a boy, she would have reached the age to serve the country.
Father Liu followed his daughter to the woodshed with suspicion. He watched as his daughter pulled out a bamboo tube from the pile of firewood and knocked it against the pile of firewood. A booklet slipped out.
After taking the booklet and flipping through two pages, Mr. Liu immediately stuffed it back into the bamboo tube and put it back in its original place. His face was as dark as water as he turned around and left the woodshed to return to the study.
Liu Yuexin was left in the woodshed.
Until dinner time, the mother and son did not dare to make a sound. They sat at the dining table and looked at the closed door.
The door opened and Mr. Liu walked out. He seemed to have aged a little.
"Eat!"
——————
The family ate in silence. The atmosphere was so oppressive that water could drip out.
After dinner, Mr. Liu walked back to the study. When he stepped into the door, he said,"Come here!"”
Mrs. Liu wanted to stand up, but Liu Yuexin shook her head with a bitter face. She tiptoed into the study and gently closed the door.
"When did it start? Beiping or Shanghai?"
"A month ago."
"A country or a country?"
Liu Yuexin shook her head.
"Nation, yes, but not Gong, can you withdraw?”
Liu Yuexin did not comment.
"Your mother and I can't leave!"
"Why?"
"If we leave, the Japanese will be suspicious. Besides, no place is safe in this world. Even if we die, we have to die together as a family! Dad will look for a job tomorrow."
"Dad!"
"You can't tell your mother about this. Trust Dad. Dad can protect you! Dad should also take a look at your booklet. There's not much content. Burn it the day after tomorrow. You memorize the first half and Dad the second half.”
——————
After that, the Liu family returned to its former glory. Father Liu was in good spirits. The next day, he went out to the application preparation team. The deputy editor there had been left for him.
The next day, Liu Yuexin put on the orchid cheongsam. She wanted to show it to him.
The following days were like a couple passing notes, but only she could read the hidden meaning behind the words. For example, don't look around and be good at observing from the corner of your eye. For example, go out with your partner more often, don't choose a fixed route, and avoid stalking and stealing. Another example was that the women's washroom was the best place to read the note, causing her to feel strange every time she read the note in the washroom.
Until one day, the note suddenly disappeared, as if it had suddenly appeared, catching Liu Yuexin off guard.
All kinds of ominous thoughts surged into her mind. However, she followed the instructions in the booklet and was not in a hurry. She only secretly lowered her guard. She opened her coat pocket wide and put on large boots. She deliberately threw away her lunch box. There was even one time when she wore everything that the person had wanted to see, which made her colleagues laugh.
However, she did not care at all. This was for him to see.
She began to pay attention to the phone and began to carefully sketch the image behind each phone through the words and the noise behind the phone.
After work, she no longer followed the fixed route and way home. She often went shopping with Xiao Hong. Xiao Hong's attention was on the fashion and leather shoes in the window. Her attention was focused on the location of the public phones, the people guarding the phones in the shops, and the environment of the shops. She compared them with her own images and modified them.
One day, she could feel that someone was following her. This came from intuition, intuition, and comprehension. This comprehension came from studying that small book.
At that time, she felt an inexplicable panic in her heart, but what was taught in the manual immediately appeared. It was the second sentence: When danger comes, being calm is the only way to save yourself. Hence, she began to observe the reflection of the window from the corner of her eye, paying attention to the direction of the paperboy's attention, as well as the focus of the hawker's gaze. Finally, she entered the mall and quickly passed through it. She went out from another door and was less than three meters away. As if she had forgotten something, she turned around and barged into the mall again.
She noticed the person who was following her. It was just a back view. She quickly flashed to a corner, and a smug smile appeared on her lips. When she went out again, the door of the streetcar was about to close. She ran two steps and boarded the streetcar one second before the door closed.
She turned around and looked at the mall again. The stalker had never shown up again.
She had already seen this streetcar before she entered the mall. She silently calculated the time when the streetcar would arrive at the station. When it left the mall a few seconds earlier, she had an idea and counter-tailed it.
The third method of the Anti-Stalking Technique was to use the environment to disrupt the rhythm of the stalker.
She had no evidence against her, not at home. Those notes and pamphlets had long turned to ashes, and the contents were all in her heart.
Therefore, she was very calm when she was being followed this time. It was as if she was playing a game.
Finally, on the morning of the second day after the stalking, the small note appeared again. This time, it was a secret code. The secret code was no longer a problem for her. Her father and she had already memorized the entire manual. With her father's guidance, she could already read and write the secret code.
In the bathroom, he began to try to decipher the secret message. The carrier of the secret message was still Morse code. She was already familiar with it, so she first translated the secret message code into Morse code and formed a set of numbers.
Then, he used the secret key to crack the set of numbers.
——————
The key taught in the booklet was based on 213 to 105 digits after the decimal point of pi, a total of 108 digits.
There were three layers to the key. The 213th digit of Pi was added to 105 to produce the first number, the 212th digit was added to 106 to produce the second number, and the 211th digit was multiplied by 107 to produce the third number. The cycle repeated, and so on. This produced 54 new numbers, which was the first layer of password.
The first set of numbers and the 108 digits of the pi key were added and multiplied to form the second set of numbers, 108 digits. This was the password for the second level.
Adding the numbers in the second group, they combined into a number that was half the original number, forming a third group of numbers, 54. This was the password to the third level.
As long as the numbers translated by Morse code were reversed with these sets of numbers, the secret message could be deciphered. According to the rules of the secret message, these three layers of codes were used in a cycle.
The numbers of the encrypted message corresponded to the German alphabets.
The German alphabets in the booklet were rearranged and numbered again. There were a total of 30 letters, and every two numbers represented a German letter.
This was the double secret code compiled by the replacement and replacement method, and it was impossible to crack. Usually, the deciphering between China and Japan was limited to Japanese and Chinese.
These days, Liu Yuexin and her father had been practicing memorizing these sets of numbers and practicing writing and deciphering the secret code.
Therefore, after a period of time, those dots and lines had practical significance.
It was a simple German sentence,'You're great, Black Hair Card!'
She suppressed her excitement and tore the note into pieces again and again. Like powder, she flushed it down the toilet.
This was her first time deciphering the secret message, the one he had sent her for the first time.
When she returned to her seat, the class monitor looked at her sympathetically and whispered mysteriously,"Buy a banana!"
Her heart was in a mess, but she still nodded helplessly and gave him a grateful look.
That afternoon, she put on the black hair clip in a show.
------
"Miss Liu, we're here!" The coachman's voice woke Liu Yuexin up from her memory.
"Oh, thank you!" Liu Yuexin was a little embarrassed.
"Miss Liu, what are you thinking about?”
"By the way, Master An, who was the last customer you invited?”
"What a coincidence today. A young man, very energetic!”
"Oh, really?"
Liu Yuexin returned home with a face full of suspicion and excitement. She went straight into her room. The note from the rickshaw was a long string of secret codes, filled with dots and strokes.
She took out the German dictionary and began to read the hidden meaning carefully.
This was an operation order, and the operation time was the day after tomorrow, Wednesday. This was not a test, nor was it a game of passing notes and tracking. It was a real operation, and her role was crucial. The operation was detailed to every detail, and it was completely from her point of view. She believed that even if someone eavesdropped, they would not suspect her.
Suddenly, she felt very sad. She buried her head in the quilt and sobbed.
It wasn't because the game had suddenly turned into a battle, but because that person had approached her not because of her, but because of her sensitive job position.
She clearly remembered that the only time she had put on lipstick was on the day of the interview. Could it be that he had been paying attention to her since then and had started to have designs on her?
A chill ran down her spine. Once she participated in this operation, she would truly embark on a dangerous path. Her life would be entrusted to someone she had never met before.
