Ning Zhiheng's words suddenly made Zhang Chengzhou speechless, he reluctantly opened his mouth, but he didn't know what to say.

Bian Ze also circled a lot of candidates for leaking secrets before this, and finally focused on these nine operational staff officers, and the reason for this is also because of this, it can be said that Bian Ze has done a very comprehensive job.

Ning Zhiheng continued: "Staff Officer Zhang, now that you are clear, I can say responsibly that the traitor must be among the nine of you, so don't shout grievances, if it weren't for your teacher, you would have been thrown into the interrogation room by now, and you would have the opportunity to sit in front of me and talk?" Also, don't always talk about the name of the Whampoa Military Academy, I am also a student of the Whampoa Academy, and I ask myself that my loyalty to the leader and the party-state is no less than yours, and tell you that even if your teacher is the guarantor, if this matter is not investigated, you will not be able to leave this place alive! ”

Ning Zhiheng's words were both warning and threatening, and every sentence hit Zhang Chengzhou's remaining self-confidence, he finally lowered his head and said weakly: "If there is anything, just ask, I will fully cooperate, but I swear to God, I am really not a traitor, even if you kill me, I will not admit to doing such a traitorous thing." ”

Ning Zhiheng saw that Zhang Chengzhou's attitude had been submissive, so he continued to ask him about some specific situations.

In fact, more than a month has passed since the case, and the questions that need to be asked, Bian Ze has already asked, as an extremely experienced veteran agent, his ability in the business is absolutely outstanding, and he is extremely thoughtful in all aspects, Ning Zhiheng is just repeating these questions when he asks again, the difference is that the purpose of his question is not in the answer itself, because no problem was found in the previous interrogation records, otherwise Bian Ze would have found out the real traitor.

The purpose of Ning Zhiheng's question is to judge whether the other party has concealed behavior by carefully observing the suspect's facial expressions, subtle movements and many other characteristics when answering, and find out the most suspicious target.

But the result made him very disappointed, because the trial time of the case was too long, and the suspect had already been mentally prepared enough in his heart, and these questions had lost their suddenness, and the so-called lie had become the truth after being told a hundred times! Even if he is a real traitor, he has established a sufficient psychological defense line at this time, at least Zhang Chengzhou did not show the slightest flaw when answering questions.

Whether it was from his eyes, from his facial features, or his body language, Ning Zhiheng did not see any problems.

In the end, Ning Zhiheng threw the interrogation record on the table and asked: "Let me ask one last question, from the beginning of December of the 26th year of the Republic of China to the middle of January of the 27th year, that is, in the month after the fall of Nanjing, your specific whereabouts, such as serving in that department?" Been to those places? Who can prove it to you? You have to explain these things clearly! ”

Ning Zhiheng did not find a flaw in the normal inquiry, so he decided to highlight the strange tricks, the four hidden ghosts he had learned from He Siming before, it was during this period of time, during the defense of Nanjing, he was captured and surrendered by the Japanese army, and then sent back to Wuhan for resettlement.

So during this time, these four inner ghosts must have broken away from their original departments or organizations, and their whereabouts cannot be proven.

Of course, there are many spies planted by the Japanese in the Chongqing area, and Ning Zhiheng cannot be sure that the ghost of this leak case is one of the four hidden ghosts.

But the reason why these people were selected to be internal ghosts in the first place was because their identities were very special, and each of them held key positions in extremely important departments of the Kuomintang and had very important intelligence value, for example, Xin Xiangrong, chief of the general affairs section of the Wuhan Station of the Military Command Bureau, was a major intelligence officer of the Military Command Bureau at that time.

And the identity of the operational staff officer of the Military Commission is also very suitable for this condition, Ning Zhiheng decided to give it a try, maybe he really gained something!

But Zhang Chengzhou's answer was still flawless, he recalled it carefully, and quickly gave an answer: "I did not participate in the defense of Nanjing, I was serving in the 54th Division at that time, serving as a major battalion commander, and later in the first battle of Songhu, the troops were all fought, and the rest of the people were withdrawn all the way to the northern suburbs of Nanjing, because there was no establishment, we were transferred back to Wuhan for resettlement, and I was transferred to the Military Committee as an operational staff officer at the beginning of December, and I have never left since then, and the commanders and colleagues around me can testify for me!" ”

As soon as Ning Zhiheng heard it, he knew that the time was not right, Nanjing fell on December 10, and at this time Zhang Chengzhou had been transferred to the Military Commission in Wuhan, and the witness was also very clear, it was not difficult to verify, of course, he still had to go to collect evidence after that.

"Alright! Staff Officer Zhang, I know all about your situation, this investigation is over for the time being, and I will look for you again if you have any questions! ”

Ning Zhiheng didn't waste time, and immediately ended this interrogation.

The interrogators escorted Zhang Chengzhou out, and the second suspect was immediately brought in.

"Staff Officer Lu..."

Ning Zhiheng's next questioning was nothing special, it was nothing more than asking the previous questions again, and at the same time observing the subtle performance of the suspect, the result was still the same as Zhang Chengzhou, for these questions, these people have already answered many times, they have been psychologically prepared, and all their performances are normal, and these combat staff officers are not ordinary people, and their psychological quality is very strong, and they did not let Ning Zhiheng find out any problems.

So Ning Zhiheng asked the question just now at the end, confirming their specific whereabouts during this time period from the beginning of December of the 26th year of the Republic of China to the middle of January of the 27th year, and these people answered them one by one.

It was not until six o'clock in the evening that all the questioning of the nine officers ended.

Back in his office, Ning Zhiheng looked at the interrogation record in his hand, thought carefully for a moment, picked up the phone and dialed out.

"Lao Shao, come to me!"

"Yes, seated!"

After a short time, Shao Wenguang, the head of the first intelligence section, hurried over, and after Zhao Jiang's communication, Shao Wenguang entered the office, and came to Ning Zhiheng in a few steps, knocked his feet, straightened his body, and respectfully saluted a military salute.

"Take a seat!"

Ning Zhiheng smiled slightly, waved his hand and said: "Lao Shao, you and I have been friends for many years, so there is no need to be so polite, this time I came back to preside over the clean-up work, and specially ordered your generals, you have to cheer up and sing this play well!" ”

For Ning Zhiheng's cordial attitude, Shao Wenguang couldn't help but feel hot in his heart, when he and Ning Zhiheng intersected slightly, his major was when Ning Zhiheng cracked the Japanese spy case, and he specially recounted his merits, which made an exceptional promotion, it can be said that Ning Zhiheng has the grace of knowing him, but in the past year, Ning Zhiheng has almost never shown up, which is a little different, but he knows that with Ning Zhiheng's level, many things don't need to be explained to him, and now Ning Zhiheng takes the initiative to talk about the past, which naturally makes Shao Wenguang feel a lot closer.

Shao Wenguang smiled and said, "Seat, don't worry, I know that this is a good opportunity, with your ability, it is not trivial to deal with Japanese spies!" I'll follow you to pick up some bargains, and it's enough for me to bear! ”

"Or can you talk, haha!" Ning Zhiheng nodded and smiled, "The leak case in northern Ganbei is the first fire in this clean-up operation, we must burn it well, the nine suspects who have just been transferred, I have already interrogated them separately, and now I need you to do one thing!" ”

"Please take a seat!" Shao Wenguang hurriedly replied.

Ning Zhiheng picked out three copies from the case file placed on the table, put them in front of Shao Wenguang, and commanded: "Cao Shaojun, Xia Bin, Lao Jingming, these three people are the suspicious points of my investigation today, I want you to do a more detailed investigation of the family environment, social relations, living habits, etc. of these three, the investigation of the headquarters is not detailed enough, you have to hand it over to me as soon as possible!" ”

Shao Wenguang's eyes lit up, just this afternoon, the director narrowed down the target of suspicion to three people, he quickly took the three files in his hand, nodded and said: "Yes, I will investigate their situation in detail and report to you as soon as possible!" ”

Ning Zhiheng chose these three people because they had doubts about the last question.

The other six people either did not participate in the defense of Nanjing, or because there were clear witnesses during that time period who could prove their whereabouts, so they could all temporarily rule out suspicion, of course, this is only temporary, if the traitors in the leak case are not this group of hidden people, everything will have to start the investigation again.

And Cao Shaojun, Xia Bin, and Lao Jingming, all three of them participated in the defense of Nanjing, and they could not prove their whereabouts during that time period.

Among them, Cao Shaojun and Lao Jingming, they were both members of the military committee who stayed in Nanjing before the war, and the situation they described was that when Nanjing was defeated, they were separated from their own large army, and then followed the refugees who fled, and they traveled for a long time before they came to Wuhan, and the witnesses on the middle road were some names that could not be verified, and now they don't know if they are in Chongqing, and they can't be found for a while, and with the current management status of Chongqing, it is estimated that they will not be able to find them in the future, that is, no one can prove their whereabouts during that time.

Xia Bin's situation was better, at that time he was the commander of the 51st Army Major Battalion stationed in Dunhua, the troops were broken up and broke through, and later he was wounded, so he hid in a common man's house in Tangshan to recuperate, and later Nanjing fell, he disguised himself as a common man, fled directly to Wuhan to return to the team, and three months later was transferred to the Military Commission as an operational staff officer.

He still remembered the name of the common man's house, but it was necessary to go to Tangshan to investigate, which was now the center of the Japanese occupation zone, and it was difficult to verify it, so he had to use the personnel of the Nanjing Intelligence Station to investigate.

Cao Shaojun and Lao Jingming are the most suspicious among them, because they were operational staff officers of the Military Commission before, and their status is special, and if they are captured by the Japanese, they can easily be selected as targets for rebellion and break into the Military Commission.

And Xia Bin, during the Battle of Nanjing, was just an ordinary major battalion commander, and after escaping to Wuhan, he was transferred to the Military Commission after three months, and it is unlikely that Japan chose him as a target for rebellion.

Ning Zhiheng also roughly narrowed down the scope of the investigation, and there is no absolute guarantee that there will be no problems for others, so everything has to wait for Shao Wenguang and the results of the investigation in other aspects to be confirmed!
