Nohara Quaner was very happy to see Sanbenjiro's face turning gloomy. Although the head of the department reaction was slower, it seemed that the head of the department also realized the importance.

"Nohara, please tell me in detail." Sanbenjiro suppressed his dissatisfaction and said in a deep voice, "I don't know much about this, you are a professional."

"Class, we have been monitoring this radio signal for a long time," Nohara Quaner said. "In the past, when this radio station contacted the outside world, the sending time was relatively long, and in a sense, it could even be described as 'unscrupulous'."

After thinking about it, thinking about the words, Nohara Quaner said, "What this radio station gives me is that they are not worried about being caught by us."

Sanbenshi Lang nodded slightly and signaled Nohara Fist to continue.

"Later, after we began to secretly use radio signal positioning equipment, the transmission frequency and transmission time of this radio station were reduced." Nohara Quaner said.

"Do you suspect they already know that we can locate radio signals?" asked Sanbenjilang.

"There is no other reason except this explanation." Nohara Nohara Nohara nodded, and he continued, "In addition, the silence of this radio station is longer than before."

"The most important thing is-" Nohara Fener raised his voice, "Today we captured the contact between this radio and the outside world, and there was only a very short boot time."

He looked at Sanbenjiro, "This is very worthy of attention, because although this radio station has shortened the time of sending the report before, it has never had such a short time of sending the report."

"Nohara, based on your experience and profession, what do you think is causing this situation?" Mibenjiro's eyes flashed with light, and he had a faint guess in his heart. Now he needs the insights of professionals.

"Although this situation is not common on this radio, it is actually not too rare among the radio signals we detect." Nohara Fener said, "The biggest possibility is that they mainly receive telegrams this time and then send a confirmation call as agreed."

"Confirm the call back..." Sandai Lang nodded slightly, which was the same as his guess just now.

"Yes, the head of the department." Nohara Fener said, "If they just receive the telegram, they don't even need to turn on the computer. They can receive the telegram with just one radio. Then, the very short boot time is when they restart the computer and reply to the confirmation message."

He looked at Sanbenjilang and continued to talk, "This is why we only detected radio signals for a very short time this time."

"I understand what you mean." Sanbenjiro smiled. He looked at Nohara Fener and said, "The situation you reported is very valuable and done well."

He decided to forgive Nohara Fist.

This kind of professional talent does not understand the worldly ways, and the other person's unintentional words are just like that. If you don't remember the mistakes of villains, you don't have to pay too much attention to them.

After hearing what Sanbenro said, Nohara Quaner was relieved. It was worth his remarks. The head of the department finally understood what it meant.

He raised his wrist and looked at the time, then frowned slightly and said, "Secretary, next time, in order to save time, my subordinates will make conclusions faster."

The smile on Sanbenshiro's face frozen at this moment, and he just looked at Nohara Fist:

Is this disliked by this guy Nohara Quaner?

Nohara Quaner saw the head of the class leader waved his hand and said goodbye and left. He felt that the head of the class leader was a little unstable today, probably because he was troubled by something.

...

Sanbenshiro told himself not to be angry and not to be aware of a guy like Nohara Quaner who is ignorant.

However, it has really been affected.

Sanbenjilang lit a cigarette and focused his energy on his work.

The situation Nohara Quaner mentioned attracted his high attention.

Receive telegram and call back to confirm.

Under what circumstances do you need to turn on the radio call back to confirm?

There are basically two situations:

One is that the other party has issued important tasks and important instructions to Shanghai.

Either they issue important notices to Shanghai, such as personnel appointments and removals.

After three days of the Lang pondering carefully, he further rejected the first possibility.

Do I need to call back to confirm when I issue important tasks and important instructions?

This is unlikely.

I used the Special High School to send secret mission telegrams to important agents hidden everywhere. For security reasons, the other party actually did not need to call back and confirm.

As long as the two parties agree to accept telegram information at a specific time, they can ensure that the task is issued and transmitted successfully.

So, is there important personnel appointments and removals?

Sanbenjilang fell into deep thought.

He had a intuition that his analysis and guess were in the right direction, but it seemed that it was still a little bit short of it.

...

"Have you confirmed the call back?" After dinner, Cheng Qianfan found an opportunity to ask Zhou Ru.

"After receiving the message, I called back to confirm immediately." Zhou Ru replied, "Lihua."

Cheng Qianfan nodded.

‘Lihua’ is a secret message. With this secret message, it means that the Chongqing Bureau Headquarters requires that you call back and confirm immediately after receiving the message, and you are waiting there.

Cheng Qianfan also understood the urgent needs of the bureau headquarters, which was related to Qi Wu's safety. He had to confirm that the special information team had received the telegram before he could rest assured.

Cheng Qianfan did not make any special arrangements for Qiwu to arrive in Shanghai.

In his opinion, everything is a priority. If Qi Wu is coming, there are any adjustments here, such as urgently dispatching people back to the city to protect, it may arouse the enemy's alertness and attention, which will backfire.

Everything is normal and be careful, so that is the best protection for the alignment.

Of course, the premise is that Qi Wu will not have any problems. If it were like Sheng Shuyu who came to Shanghai last time, it would be bad. His Shanghai special recruitment team can no longer afford to have a new deal.

...

The next day, in the evening.

Spring breeze and delightful building.

"Brother Fan, there are further clues." Haozai reported to Cheng Qianfan.

"Tell me," said Cheng Qianfan.

"A new teacher has come to Qingxin Middle School." Haozai said.

"Teacher mathematics?" Cheng Qianfan asked casually.

"No." Haozi shook his head, "It's taught British words."

He took a sip of water and continued, "The information my brothers inquired about, this man's surname is Xie Guanglin. He returned from studying abroad in Citigroup and was preparing to return to his hometown in Fujian. However, because he was sick, he was stranded in Shanghai, so he was recommended by a friend to make a living by a temporary class."

Returning from studying abroad in Citigroup.

Sick and stayed.

Without a professor, he became a substitute teacher in English. This seems to show that this person is quite smart and knows how to hide himself. This seems to explain why this person can hide these days.

An inexplicable smile appeared on the corner of Cheng Qianfan's mouth.

Although all this seems to be so reasonable:

This person is Ren Anning, and Ren Anning has sufficient reasons to hide these days.

However, Cheng Qianfan is now 80% sure that Ren Anning has a problem-

Since the news of suspected Ren Anning came out, clues have been one after another, which gave him the feeling of a pair of hands pushing him behind his back, pushing him to find this person and Ren Anning.

He was unable to determine whether Ren Anning was really Ren Anning now, but there must be problems here.

"Is there any other evidence to prove it?" Cheng Qianfan asked again.

"Yes." Haozai nodded, "According to your instructions, we found the person's registered name through the ancient ship. The person was named Liu Lin. The most important thing was that we found a passenger in the same cabin. The person recalled that Liu Lin said that he was from Fujian and wanted to go back to his hometown in Fujian."

Cheng Qianfan nodded and thought to himself, sure enough, the evidence was chained up and neatly.

"Arrange brothers to closely monitor Xie Guanglin." Cheng Qianfan said, "Be careful."

"I understand." Haozai nodded.

Brother Fan understood what he meant. He must not use the personnel involved in the special situation team in the entire operation. It must be absolutely clean and no hidden dangers.

...

Xizilai Huoxing Street.

A Shikumen house.

The wattage of the incandescent lamp is very small and the light is dim.

Suddenly, the light bulb went out.

"Is the light bulb broken?" Lei Zhiming asked.

"The power outage." A male voice replied. The man skillfully took out the foreign fire box and drew a foreign fire to ignite the kerosene lamp.

"We have found Ren Anning." The man said to Lei Zhiming.

"Is that true?" Lei Zhiming was overjoyed, "It's so good, how did you find it? Where is the person?"

"Cheng Qianfan's people are looking for Ren Anning. We have comrades who are mixed with the scoundrel of this 'Little Cheng', and successfully found Ren Anning through their strength." The man said, "Mr. Ren is now using Xie Guanglin's pseudonym, and temporarily resides in Qingxin Middle School. "

"Comrade Qi Peng, can you be sure that this person is Ren Anning?" Lei Zhiming asked seriously.

"The news from Cheng Qianfan and the situation we learned from the side, this teacher Xie should be the Mr. Ren Anning who came back from Citigroup." Hong Qipeng said, "However, for safety reasons, I think it is necessary to confirm it."

"What do you mean by the Student Affairs Committee?" Lei Zhiming asked with a serious expression.
