Ning Zhiheng's words immediately made Zhang Chengzhou lose his words. He forced him to open his mouth, but he didn't know what to say.

Eizawa had also identified many candidates for leaking secrets before, and finally focused his target on these nine combat staff members. The reason is also because of this. It can be said that Eizawa has done his work very comprehensively.

Ning Zhiheng continued: "Staff Officer Zhang, now you know it. I can say responsibly that the traitor must be among you nine, so don't complain. If it weren't for your teacher, you would have been thrown into the interrogation room and served him. I would have the chance to sit in front of me and talk. Also, don't always talk about the title of the Whampoa Military Academy. I am also a student of the Whampoa school. I ask myself that my loyalty to the leader and the party and the country is no less than you. Tell you that even if your teacher is the security guard, you will not be able to leave here if you don't find out this matter clearly!"

Ning Zhiheng's words were warnings and threats, and every sentence hit Zhang Chengzhou's remaining confidence. He finally lowered his head and said powerlessly: "If you have anything, just ask me. I will definitely cooperate with you. But I swear to God that I am really not a traitor. Even if you kill me, I will not admit to doing such a traitor."

Ning Zhiheng saw that Zhang Chengzhou's attitude had become obedient, so he continued to ask him about the specific situation.

In fact, more than a month has passed since the case. Bianze has asked all the questions that need to be asked. As a veteran agent with extremely rich experience, he has absolutely outstanding business skills and considers all aspects of his consideration. Ning Zhiheng asked again but repeated these questions. The difference is that the purpose of his question was not the answer itself, because no problem was found in the previous interrogation records, otherwise Bianze would have found the real traitor.

The purpose of Ning Zhiheng's question is to carefully observe the suspect's facial expressions, subtle movements and other characteristics when answering, and to find the most suspicious target.

But the result disappointed him very much. Because the trial of the case was too long, the suspect had already made enough psychological preparations in his heart. These questions had lost their suddenness. The so-called lies were told a hundred times and it became the truth! Even a real traitor had established enough psychological defense at this time. At least Zhang Chengzhou did not reveal any flaws when answering the questions.

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

Finally, Ning Zhiheng threw the interrogation record on the table and asked, "I will ask one last question: From early December 26th to mid-January 27th, that is, a month after the fall of Nanjing, your specific whereabouts, such as in which department, have you been to those places? Who can prove it to you? You must explain these situations clearly!"

Ning Zhiheng did not find any flaws in his normal inquiry, so he decided to highlight his strange tricks. The four hidden inner demons he had learned from He Siming were captured and surrendered by the Japanese army during this period of time during the Nanjing Defense War, and were then sent back to Wuhan for resettlement.

So during this period, these four insiders must have separated from their original departments or organizations, and their whereabouts cannot be proven.

Of course, there are many spies installed in Chongqing now, and Ning Zhiheng is not sure that the insider in the leaked case is one of these four hidden insiders.

However, the reason why these people were selected as insiders was because their identities were very special. Each of them held key positions in extremely important departments of the National Party and had very important intelligence value. For example, Xin Xiangrong, the general affairs section chief of the Wuhan Station of the Military Intelligence Bureau, was the major intelligence officer of the Military Intelligence Bureau at that time.

The identity of the Military Commission's combat staff also meets this condition. Ning Zhiheng decided to give it a try and maybe you will really gain something!

However, Zhang Chengzhou's answer was still flawless. He recalled carefully and quickly gave the answer: "I did not participate in the Nanjing Defense Battle. At that time, I served in the 54th Division and served as the major battalion commander. Later, in the Battle of Songhu, all the troops were fought, and the remaining people retreated to the northern suburbs of Nanjing. Because there was no organization, we were transferred back to Wuhan to relocate. In early December, I was transferred to the Military Commission as combat staff. Since then, I have never left. The commanders and colleagues around me can testify for me!"

Ning Zhiheng knew that time was not up to date. Nanjing fell on December 10th. At this time, Zhang Chengzhou had been transferred to the Military Commission in Wuhan, and the proof was also very clear. It was not difficult to verify. Of course, he still had to collect evidence later.

"Okay! Staff Officer Zhang, I understand your situation. This investigation has come to an end for the time being. If you have any questions, I will look for you again!"

Ning Zhiheng was not wasting 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 inquiry was nothing special. It was just to ask the previous question again and observe the suspect's subtle performance. The result was the same as Zhang Chengzhou. These people have answered these questions many times, and have been mentally prepared. All performances are normal. Moreover, these combat staff are not ordinary people, and have strong psychological qualities, so they did not let Ning Zhiheng find any problems.

So Ning Zhiheng asked the question he had just said at the end and confirmed that their specific whereabouts during this period from early December to mid-January 27, these people answered one by one.

It was not until six o'clock in the evening that the nine officers' inquiries were all over.

When he returned to his office, Ning Zhiheng looked at the interrogation records in his hand, thought carefully for a moment, picked up the phone and called out.

"Old Shao, come to me!"

"Yes, Seating!"

Soon, Shao Wenguang, the head of the Intelligence Section 1, hurried over. After Zhao Jiang's report, Shao Wenguang entered the office and came to Ning Zhiheng a few steps. He knocked his feet, straightened his body, and respectfully saluted.

"Satisfied!"

Ning Zhiheng smiled slightly, waved his hand and said, "Old Shao, you and I have been together for many years, so you don't have to be so polite. This time I'll come back to preside over the cleaning work and specially ordered your generals. You must cheer up and sing this drama well!"

Shao Wenguang couldn't help feeling warm about Ning Zhiheng's kindness. When he and Ning Zhiheng had a short time, he, the major, was when Ning Zhiheng cracked the Japanese spy case, and he specifically recounted his merits, which was why he improved. It can be said that Ning Zhiheng had the kindness of knowing him. However, this year, Ning Zhiheng almost never showed up, so he became a little distant. However, he knew that at Ning Zhiheng's level, there was no need to explain many things to him. Now Ning Zhiheng takes the initiative to reminisce about the past, which naturally makes Shao Wenguang feel much closer.

Shao Wenguang smiled and said, "Don't worry, I know this is a good opportunity. With your ability, it's not a slightest point to dealing with Japanese spies! I'll follow you to get some bargains, which is enough for me to endure!"

"You can speak, haha!" Ning Zhiheng nodded and smiled, "The leak case in northern Ganzhou is the first fire in this clearance operation. You must burn it. I have interrogated the nine suspects who have just been transferred. Now you need to do one thing!"

"Please give me instructions!" Shao Wenguang quickly stood attentively and replied.

Ning Zhiheng picked out three copies from the case sect placed on the table, placed them in front of Shao Wenguang, and ordered: "Cao Shaojun, Xia Bin, Lao Jingming, these three people are the doubts I have investigated today. I want you to conduct a more detailed investigation on the family environment, social relations, living habits, etc. of these three. The investigation at the headquarters is not detailed enough, you must hand it over to me as soon as possible!"

Shao Wenguang's eyes lit up. However, in the afternoon, the director narrowed his 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 on the last question.

The other six people either did not participate in the Nanjing Defense War or had clear proofs during that period to prove their whereabouts, so they could temporarily eliminate suspicion. Of course, this is only temporary. If the traitors in the leaked case were not this group of lurking personnel, everything would have to start a new investigation.

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

Among them, Cao Shaojun and Lao Jingming were both members of the Military Commission left behind in Nanjing before the war. The situation they described was that when Nanjing was defeated, they were separated from their large troops. Later, they followed the refugees who fled for a long time before they arrived in Wuhan. The proofs on the road in the middle were all unverifiable names. They don’t know whether they are in Chongqing or not, and they can’t find them for a while. Given the current management status of Chongqing, it is estimated that it will not be possible to find them in the future. In other words, no one can prove their whereabouts during that period.

Xia Bin's condition was better. At that time, he was the major battalion commander of the 51st Army stationed in Dunhua. After the troops were dispersed, they broke through. Later, they were injured and hid at the home of a commoner in Tangshan to recover from their injuries. Later, Nanjing fell, so he disguised himself as a commoner and fled directly to Wuhan to return to the team. Three months later, he was transferred to the Military Commission as a combat staff officer.

He still remembers the name of the family of the common people, but this requires investigation in Tangshan. It is now the center of the Japanese-occupied area. It is difficult to verify it, so he can only use personnel from the Nanjing Intelligence Station to investigate.

Among them, Cao Shaojun and Lao Jingming are the most suspicious because they were the combat staff of the Military Commission before. They had a special status. If they were captured by the Japanese, they would easily be elected as targets of rebellion and invaded into the Military Commission.

Xia Bin was just an ordinary major battalion commander during the Nanjing Defense War. Later, after fleeing to Wuhan, he was transferred to the Military Commission three months later. It is unlikely that Japan would choose him as the target of instigation.
