Hearing Wang Hanmin's words, Ning Zhiheng looked at him in surprise, and said in his heart that something really happened, no wonder Wang Hanmin was so anxious to see him.

Ning Zhiheng asked in a deep voice, "Stationmaster, did you have a problem on the way here?" ”

Wang Hanmin said helplessly: "Yes, just yesterday morning, at the last checkpoint to enter Shanghai, three members of my team were detained by the Japanese garrison!" ”

When Ning Zhiheng heard this, he was shocked, and quickly asked, "What is the reason?" Identity revealed? ”

"No, they were forcibly requisitioned by the local garrison!" Wang Hanmin shook his head and said.

He began to recount the matter carefully, it turned out that this time Wang Hanmin selected 50 headquarters agents to rush to Shanghai to take up their posts, they disguised themselves as personnel of a commercial bank, mixed in the convoy of a commercial bank, and the journey went smoothly, and passed several checkpoints safely, but when they were about to pass through the Jingshui Bridge in Shanghai, there was still an accident.

Jingshui Bridge is located in the western part of Shanghai on the main road of a bridge, when the Songhu War retreated, it was blown up by the Japanese plane, and was repaired after the war, because it is located on the main transportation line, the geographical location is important, the Japanese set up a checkpoint here, guarded by the garrison of Shanghai, its main purpose is to check the flow of goods from Shanghai to the mainland.

Ordinary pedestrians and ordinary goods can pass, but as long as suspicious people and smuggled controlled goods are found, the goods will be immediately seized and suspicious persons will be arrested.

Because the caravan where Wang Hanmin and the others were hiding entered Shanghai, the Japanese were not strict with the inspection of the caravan entering Shanghai, so the convoy in front passed smoothly.

But just as the convoy was about to pass through, an officer suddenly came and ordered a group of men and vehicles to be requisitioned to help them build the garrison's barracks.

It turned out that the military headquarters ordered that the garrison at the Jingshui Bridge checkpoint should be strengthened, so the temporary military camp here should be expanded.

This time, the convoy that did not pass behind was all unlucky, and all vehicles and personnel were forcibly requisitioned, but there were three agents from the headquarters inside.

Later, the person in charge of the trading house went to negotiate with the Japanese, and stuffed a lot of money into it, but it didn't work at all, and he almost didn't even come back, and finally the Japanese hit his head with the butt of a gun and broke his blood and kicked out of the barracks.

Wang Hanmin was also helpless about this, during this period, all the military and political power in Shanghai was in the hands of the Japanese, and the Military Intelligence Investigation Office had no relationship in Shanghai that could be used at all, so he could only lead the other team members to enter the Shanghai concession first, and personally came to the door to seek help from Ning Zhiheng to find a way to rescue these three team members.

Ning Zhiheng thought for a moment when he heard this, and then asked, "Does the person in charge of this firm know your identity?" ”

Wang Hanmin hesitated for a moment, knowing that he couldn't hide it, so he nodded and said: "He is also our person, this Fengmao Commercial Bank was originally opened by our military intelligence department, and its purpose is to open up the transportation channel between the mainland and Shanghai, which is also part of the power handed over to me by the department, I didn't expect to make a mistake when I entered Shanghai for the first time." ”

It seems that the seat has done a lot of work for Wang Hanmin, and the intensity of investment has also increased a lot, Ning Zhiheng couldn't help but sneer in his heart, but unfortunately this is in Shanghai, and the seat can't help but take it for granted.

"When he went to negotiate, didn't he ask clearly, when would the Japanese release him?" Ning Zhiheng then asked.

"I asked, the Japanese said that they would release the people after the barracks were built, and it would take at least twenty days!"

Ning Zhiheng couldn't help but wonder a little, since the identities of the three team members had not been revealed, at most they were only working as coolies in the Japanese for twenty days, shouldn't Wang Hanmin be so nervous?

"Stationmaster, you still have to explain some situations to me clearly, otherwise I won't be able to arrange a rescue operation, is there a problem with the identities of these three people?" Ning Zhiheng asked directly.

Wang Hanmin knew that it was difficult to hide from Ning Zhiheng, so he had to tell the truth: "One of the team members is called Zhang Yong, and he is my telecommunications section chief!" ”

Ning Zhiheng immediately reacted, and asked urgently: "The code book is on him?" ”

Wang Hanmin nodded helplessly, this is why he is in such a hurry to rescue people.

If Zhang Yong is allowed to be locked up in the barracks for such a long time, who can guarantee that the codebook on his body will not be discovered by the Japanese.

Once discovered, the identities of Zhang Yong and others will inevitably be exposed, and then a series of arrests will follow, the newly established Fengmao Commercial Bank, and Wang Hanmin's intelligence station will be exposed to the sight of the Japanese.

What's more important is this codebook! It turned out that in the past two years, the telecommunications section of the Military Intelligence Investigation Department has developed rapidly, and the code-breaking team secretly set up has made a major breakthrough, not only deciphering the Japanese military's telegrams many times, but also designing a new codebook for itself and a new editing and calculation formula, which has raised the degree of cipher secrecy of the Chinese military to a higher level, and now the Japanese spy department has been unable to decipher the Chinese military's telegrams for a long time.

In this, the several encrypted codebooks seized by Ning Zhiheng played a very big role.

However, just as the Military Intelligence Investigation Department tried its best to seize the Japanese codebook, now the Japanese are also making great efforts to find the latest codebook of the Chinese military, in order to find the decipherment pattern in it.

Now the whereabouts of the codebook are unknown, such a serious situation, so that Ning Zhiheng is no longer calm, if the codebook is seized by Japan, although as for this time, the Japanese found a way to decipher the code of the Chinese military radio, but it can provide a reference blueprint for Japanese cryptography experts, how much loss there is, no one can estimate.

You must take the codebook back at all costs, Ning Zhiheng thought of this, and couldn't help but feel a little annoyed in his heart, Wang Hanmin's ability is indeed not outstanding as Zheng Hongbo said.

Although Zheng Hongbo's ability is not outstanding in Ning Zhiheng's eyes, it is enough to be worthy of the four words of rich experience, great changes, protrusions, and chaos in the face of danger, quickly deal with the tail of the hand, and arrange for the evacuation of hundreds of subordinates in time, without the slightest mistake.

However, this Wang Hanmin made such a big mistake as soon as he arrived in Shanghai, although it was an accident, it can also be seen that his organizational skills are not satisfactory.

To be honest, just by virtue of this article, if Ning Zhiheng catches on and falls into the well, he can make Wang Hanmin unable to eat and walk around, make him unable to gain a foothold in Shanghai, and achieve Deputy Director Huang's original goal.

However, Ning Zhiheng has his own bottom line in doing things, and he can't do anything to step on the blood of his robe and climb up, so what is lost is the strength of the Chinese themselves.

At this point, he must not stand idly by, and must rescue the three agents to ensure the safety of the codebook.

"Stationmaster, you give me the pseudonyms of these three team members, I will take rescue action immediately, the emergency contact channel between me and Stationmaster Zheng is still there, as soon as there is news, I will contact you as soon as possible." Ning Zhiheng said.

Wang Hanmin had such a big problem as soon as he came to Shanghai, how did he not know the seriousness of the matter, he didn't want to ask Ning Zhiheng for help, for fear that he would catch this matter and fall into the ground, but if he didn't get the codebook back and let it fall into the hands of the Japanese, his guilt would be greater.

"Thank you so much, Zhiheng, I first came to Shanghai, and the people and land are unfamiliar, so it's all up to you!" Wang Hanmin held Ning Zhiheng's hand and said gratefully.

The two of them then talked about some details, and then left separately, and Ning Zhiheng returned to the Tan Mansion to carefully consider the solution to this matter.

At this time, the Japanese garrison had just been stationed in Shanghai for half a year, and had no contact with all sides, and the strength of its own intelligence station was limited, and it could not find a relationship that could affect the Japanese, so they could only find a way to get rid of it.

It seems that the work is still done through Ishikawa Takeshi, the Japanese military police is the police in the Japanese army, and the military police headquarters where Ishikawa Takeshi is located has the privilege of supervising the army's violations of discipline and law, and at the same time maintains military discipline, manages public order, and supports a series of rights in combat.

As Ishikawa Takeshi's gendarmerie Shaosa, he should be able to control a garrison officer, but there is a certain risk in doing so, but for the sake of the codebook, this risk must be taken!

The next day, Ning Zhiheng rushed back to downtown Shanghai and came to the military police headquarters.

"Fujiwara-kun! How did you get here? You're here to find Ishikawa-kun, right? ”

"Tsuda-kun, are you on duty today?" Ning Zhiheng greeted with a smile.

Tsuda Naoki is a colleague of Ishikawa Takeshi, and he is also one of the officers of the military police headquarters who originally intersected with Ning Zhiheng, but his status is not as good as that of an aristocratic officer like Ishikawa Takeshi, he was born a commoner, so he has no real power, and he is usually responsible for miscellaneous affairs such as public security on duty, and has always been the role of Ishikawa Takeshi's follower.

He drank and chatted with Ishikawa Takeshi and Ning Zhiheng many times, and later Fujiwara Club opened, he also went to celebrate, the two of them are also familiar friends, naturally know that Ning Zhiheng's identity is noble, especially the background behind him is amazingly big, and now he is the big boss of Dojin, so when he saw Ning Zhiheng, he was quite enthusiastic.

"It just so happens that Ishikawa-kun has just returned, and I'll take you to his office!" Naoki Tsuda reached out and made a gesture of please.

Under his guidance, Ning Zhiheng entered the gate of the military police headquarters.

The military police headquarters is very heavily guarded, and it is the highest body that manages the security of Shanghai, and its authority is very great. But at the same time, this place is also known as the man-eating demon cave, almost all the Chinese citizens who were arrested on various charges have to be handed over here to deal with in the end, but basically there are people in and out, those who are sent in are living people, and those who are carried out are corpses, so when it comes to the Japanese military police headquarters, all the people are discolored!
