It didn't take Han Nina an hour to accurately decipher this super-encrypted message, looking at the deciphered message, she shook her head and said to herself: It is completely possible to send a one-time message with a second-level encryption frequency, which is purely superfluous.

At 8:15 a.m., the Telecommunications Office received a telegram personally signed by Liu Zexian, the head of the Yichang Military Command Station, which stated that Lei Yunfeng was suddenly bombed by three Japanese bombers at 7.45 a.m.

The Japanese transport plane, which was parked on the runway and was about to take off, was destroyed on the runway by three Japanese bombers, and all its crew members were killed.

This news shocked the entire telecommunications department, and Director Wei, who had a keen antennae, did not dare to delay for half a second after receiving this message, and immediately drove the message to Director Shen of the inspection office in person.

Han Nina was also taken aback when she saw the contents of this telegram, and immediately found the deciphered message, and after repeated study, she finally suddenly became enlightened, and left the office with a relaxed humming tune.

Less than half an hour after receiving this telegram, the bureau headquarters sent someone to isolate all the personnel on duty in the telecommunications office from 4:20 to 8:00, even Han Nina.

Han Nina immediately realized vigilantly: the bureau headquarters isolated these personnel separately and conducted a secret review one by one, indicating that they had received the first second-level encrypted message from Lei Yunfeng, indicating that they were expected to take off on time at 8 o'clock in the morning.

However, it was suddenly attacked by three Japanese bombers at 7.45, which completely destroyed the Japanese military transport plane that was already on the runway at this time and was about to take off, and Lei Yunfeng hijacked, resulting in the tragic incident of plane destruction and death.

What does it mean that the three Japanese bombers were able to suddenly lock on the runway from the air when the transport planes were about to take off, and carried out a sneak attack very accurately?

After a quick analysis, Han Nina not only trembled and said secretly: The Japanese bomber was able to accurately grasp the time when the transport plane hijacked by Lei Yunfeng took off from Yichang, indicating that it received the leak of the content of the secondary encrypted message sent by Lei Yunfeng at 4:25.

In less than half an hour, Liu Zexian, the head of the Yichang Station of the Military Command, personally signed the telegram, and the bureau headquarters sent inspectors to break into the telecommunications office in such a short time.

And the personnel on duty who received the first telegram from Lei Yunfeng, and the time was from four to eight o'clock, were isolated and examined separately, what does this mean?

It shows that Lei Yunfeng's second-level encrypted message was leaked by the Japanese puppet spies lurking in the bureau headquarters in the most secret and fastest way to the Japanese high-level soldiers, and the Japanese high-level who obtained such top-secret information immediately sent three bombers to prepare for battle.

According to the endurance time, the Japanese bombers calculated that they should rush to Yichang Airport before eight o'clock and carry out a sneak attack on the transport plane on which Lei Yunfeng was about to take off.

The three bombers dispatched by the Japanese high-level who received the information successfully carried out a sneak attack and destroyed the transport plane parked on the runway ready to take off, achieving the brilliant result of destroying the plane and killing people.

Han Nina will receive a telegram from Liu Zexian of the Yichang Station of the Military Commander, and two telegrams sent by Lei Yunfeng at 4:25 and 4:30, and analyze them together, but in the end they did not come up with a satisfactory result.

In the end, she believed that it was very likely that Lei Yunfeng had adopted the trick of transferring flowers and trees, and left Yichang Airport ahead of schedule according to the time stated in the second special encrypted message.

The transport plane destroyed by the three Japanese bombers on the runway for take-off was nothing more than an illusion, or a model, or a scrapped fighter.

What puzzled Han Nina was what Lei Yunfeng was doing this? Is it for ....... She's not a nosy person, and since everything has happened and she's been quarantined for scrutiny, she keeps silent and doesn't say anything, just let it go.

What is even more questionable is that on the fourth day of this incident, today, a new Miss Su Yan suddenly came to the Electricity Supervision Department, which aroused Qi Xiaomeng's interest and proposed to hold a welcome party for the whole department.

Han Nina rarely participated in this kind of boring party, but she didn't object at the time, when Su Yan offered to invite her, she just catered to Qi Xiaomeng, an enthusiastic little guy, and proposed to invite Shang Feng, who had just reported today, to Fang Chao together.

Qi Xiaomeng trumpeted how the newcomer Shang Feng was suave, which was simply the reincarnation of Pan An, which aroused Han Nina's interest.

Lei Yunfeng, who had been listening carefully to Han Nina's explanation, suddenly asked, "Miss Han, you won't change your mind and want to participate in this party organized by Su Yan, and you want to see what kind of character Shang Feng is like to me, a handsome young officer, right?" ”

"You're right, I mean this, but it's by no means as vulgar as you say, mainly because I'm attracted by the name of this newcomer, Shang Feng, because I remember that in the few telegrams I received, I had a vague impression of this name.

The second is that I suspect that three newcomers have suddenly come to report today, and that there must be something to do with this incident, and to confirm this, I agreed to attend the meeting. ”

"Now you've got there? And what can be confirmed? Lei Yunfeng listened to Han Nina's statement here, not only looked at Han Nina very playfully and asked again.

"I have been confirmed, in the few telegrams I remember, the name of Yun Shangfeng has appeared, and the 'Shang Feng' who came to report today should be that Yun Shangfeng, but it is just a homonym of the two words after the name.

During the cafeteria meeting, I deliberately paid attention to Su Yan's eyes, and read from her eyes that she knew you, Shang Feng and Fang Chao, and was very familiar, Major Shang, wasn't she? ”

"Miss Han, I don't make any comments on your bold speculation, I don't know why you told me that the suspect was locked up within one day of my report, why?"

"Reasoning and analysis, the arrival of the three of you should be with a special operations team to solve the case, although you did not identify yourself, but you are still a major, intentionally or unintentionally, using your suave appearance to attract the attention of everyone in the telecommunications department, in order to get your attention.

The purpose is to tell everyone that your arrival is normal and has nothing to do with the leak of the message, and try to keep a silent posture, but it backfires, and your arrival immediately attracts everyone's attention, which is also the effect you hope to achieve. Major Shang, isn't it? ”

"Why am I doing this? Miss Han didn't think that my stupid approach would surprise the snake too much, so why didn't she just reveal my identity and show that the mission I was going to carry out when I came here was to solve this espionage case? ”

"This is your stupid way to achieve mastery, that is, to startle the snake and force the Japanese pseudo-agent lurking in the headquarters of the bureau to show his flaws in his restlessness, as long as he is caught by you, with your ability, he will never be asked to slip away."

Han Nina was talking when she suddenly paused, looked at Lei Yunfeng and asked suspiciously: "Major Shang, since you already suspect that there are Japanese puppet spies lurking in the bureau headquarters, why don't you take the most covert means to detect, but go to great lengths to play a Japanese bomber sneak attack on the airport in Yichang, causing the illusion that the plane is destroyed and people are killed?" ”

"Miss Han asked well, I doubt but am not sure, so I can only take this way, through the two telegrams sent to see if there are any hidden Japanese puppet spies in the bureau headquarters.

Once the message is leaked, the bureau headquarters will detect it according to the scope of the lock, so that there will be a target. In the case of suspicion, we will not take the preemptive action to create a momentum, which will bring the inconvenience and trouble caused by the next step in solving the case. ”
