…
At dusk, the sky is filled with red clouds, and the whole sky seems to be dyed red, gorgeous and colorful.
In the distance, just as the sun was setting, the buildings outside the window were passing by rapidly.
A Buick car drives smoothly on the road.
"I don't know what your attitude is towards us revolutionaries, Yu Hua..." Lin Wan sat in the back seat, staring at the scenery outside the window, silently recalling the content of today's conversation in her mind, from Comrade Professor's A military comment hit her heart like a heavy hammer.
It turns out that a person can be so good.
It has never happened since ancient times that one person can defeat an army.
Not to say it is unprecedented, but it is definitely unprecedented!
Lin Wan didn't know what Yu Hua's attitude would be towards these group of revolutionaries who were dubbed "**".
Refuse, or agree?
Lin Wan was thinking about this matter silently in her mind. The Buick turned left along Xishiku Street and continued driving for a while before arriving at the gate of Peking No. 4 Lieutenant Colonel.
"Comrade Qingluan, pay attention to safety. I am Yang Xiu, the head of the protection team. You can call me Team Leader Yang. During this period, except in the school, we will protect you 24 hours a day, in the dark and light. If there is an emergency, If the situation arises, make a distress signal immediately." After the Buick parked safely, Yang Xiu, the head of the youth protection team who was sitting in the passenger seat, turned around and reminded Lin Wan.
With the official launch of the seven-tower installation plan, the Northern Department specially upgraded Lin Wan's protection level. Northern Special Branch implemented 24-hour uninterrupted protection, one in the dark and one in the dark, with a total of two groups of four people. As long as Lin Wan left the school, the protection Measures were taken immediately.
This is the protection level second only to the core personnel of the Northern Department. It is only two levels away from the highest-level professor comrades, which is not unimportant.
"I understand, sorry for the trouble, comrades." Lin Wan nodded and thanked her softly.
Yang Xiu looked serious and meticulous, and responded sternly: "No, it's all for the revolution."
"Everything is for the revolution." Lin Wan nodded, opened the car door and got out of the car, bid farewell to the members of the protection team, passed through the gate of No. 4 Middle School, and headed towards the dormitory, ready to rest.
Today's intense exam, after the joint exam, there was also a conversation, and Lin Wan was already a little tired.
"Hello, Chairman."
"Hello."
"Hello, senior Lin Wan."
"Hello."
On the way, I briefly said hello to some students in the second and first grades of high school.
Soon, Lin Wan returned to the dormitory door and was about to go upstairs. Suddenly, a voice came from the side. The dormitory aunt shouted to Lin Wan: "Lin Wan, your email."
"Email? Who will send me the mail...wait a minute!" Lin Wan looked puzzled. As she thought about it, she suddenly felt that the scene in front of her seemed similar. She suddenly remembered who would send her the mail, and her pupils suddenly twitched. Shrinking, he stepped forward and quickly took a package about the size of a drawer from the hands of the dormitory aunt.
Lin Wan couldn't wait to look down, pointing directly at the package mail list, and a series of information suddenly came into view.
Receiving address - Beiping No. 4 Middle School, Xicheng District.
Recipient - Lin Wan.
Sender - Zhang San.
My dear classmate Lin Wan.
Zhang San!
Sure enough, the sender was Mr. Zhang San. This was the second time a similar package appeared!
"Auntie, when was this package sent?" After confirming the package delivery information, Lin Wan's heart condensed, her face remained normal, and she asked the dormitory aunt.
The dormitory aunt recalled it in her mind, gave the time, and wondered: "What happened yesterday afternoon?"
"Nothing, thank you, auntie." Lin Wan couldn't help but feel nervous after getting the package delivery information. Fortunately, the package was not lost. She immediately thanked the dormitory aunt and said goodbye, then turned and walked towards the school gate.
Whether you are tired or rested, it doesn't matter in front of this package. Matters related to Mr. Zhang San must be dealt with immediately.
Lin Wan's steps were fast and her movements were agile. It didn't take long for her to arrive at the school gate and head to the opposite side of the road. The young man standing on the opposite side of the road was Yang Xiu. When she saw Lin Wan's hurried figure, she immediately cheered up, eyes in her eyes. He showed a vigilant look and looked around to see if there were any unusual persons.
Fortunately, everything is fine.
Yang Xiu made a gesture to Lin Wan, and when Lin Wan crossed the road with the package, he walked forward and said, "What's the matter, classmate Lin?"
"Team Leader Yang, I didn't have time to elaborate. I went to the teahouse immediately. I received a package from Mr. Zhang San. The contents inside are very important." Lin Wan said roughly with a serious face.
"Okay, please follow me." When Yang Xiu heard the name Zhang San, he immediately became extremely vigilant. As the chief of the Northern Special Operations Unit, he certainly understood the weight of the name Zhang San. He was a Special Branch officer. One of the few people authorized by superiors to know some information about Mr. Zhang San.
After finishing her words, she led Lin Wan to leave.
Not long after, the two got into a Buick and quickly headed to the teahouse.
…
Nancheng District, Zhiyuan Teahouse.
A conference room located in the backyard of the tea house.
Lin Wan, the top person in charge of the Northern Department, whose pseudonym is Liu Wei, the "Professor", and the Secretary-General of the Northern Department, who is responsible for recording information, gathered in the conference room.
"This is the second package that Mr. Zhang San has sent to us. It is very important. Secretary-General, all the following information will be at the highest top secret level and will be handed over to me for review after the meeting." Liu Wei sat at the main seat with a solemn face. He took out a cigarette and lit it out of habit, took a puff, looked at the Secretary-General with eyes like torches, and confessed.
All information involving Mr. Zhang San must be kept strictly confidential and be careful to prevent leakage. This is the most basic requirement.
Mr. Zhang San published "Chinese Mechanical Drawing". That was his choice, but the Northern Ministry must not reveal any information about Mr. Zhang San, because it involves crucial red secret deciphering information.
"Yes!" The secretary-general nodded in agreement, then opened his notebook and prepared to record information.
After the relevant matters were explained, Liu Wei looked at Lin Wan: "Qingluan, the package says Lin Wan personally expresses it, please open it."
"yes."
Lin Wan took a deep breath, responded, looked at the package, picked up the knife on the table, and opened the package.
In the package, there was a notebook, a collection of arithmetic problems, and a stack of dictionary-like manuscript paper about ten centimeters thick. Looking at these three ordinary items, Lin Wan looked serious. The professor in the conference room He and the secretary-general held their breath, not daring to be careless at all.
Lin Wan took out all three items and placed them on the table. Then she picked up the notebook with ease and opened the first page. It turned out to be a derivative question from high school mathematics.
The draft paper was placed on the table. She held the pen in her right hand and carefully reviewed the problem. Under the gaze of the professor and the secretary-general, Lin Wan solved this difficult mathematical problem.
This question is no less difficult than the last question in yesterday's joint arithmetic test paper.
Ten minutes later, the correct answer appeared after three calculations - 152.
"Huh..." Lin Wan let out a breath, put down her pencil, opened the arithmetic problem book based on the answers, and quickly turned to page 152.
Just like before, pages 152 and 153 were specially processed to form a whole, with a gap between the two pages and a piece of letter paper placed in the middle.
Looking at the familiar letter, Lin Wan's heart beat faster and her eyes were filled with anticipation. She carefully took out the letter and opened it under the gaze of the two professors.
Classmate Lin Wan, I am Zhang San...
