Sun Jiacheng was Ning Zhiheng's most capable and trusted confidant. He was highly skilled in martial arts and was originally a good detective in the army. Later, he joined the Military Intelligence Investigation Department and received special training. He had a wealth of experience in surveillance and tracking and had never failed to track a target. It was quite unexpected for Ning Zhiheng that he had lost track of the target today.

Actually, Ning Zhiheng had a bad feeling ever since Miao Yongyi suddenly proposed to join the Military Intelligence Investigation Department. He knew Miao Yongyi well and knew that Miao Yongyi disliked being a secret agent. However, when he thought that the two brothers would never have to be separated again and that Miao Yongyi would not have to risk his life to fight and could live safely, he thought that was more important than anything else, so he agreed.

Even if it's his own brother, it doesn't mean he won't screen Miao Yongyi. That's why he temporarily kept Miao Yongyi in the safe house to recuperate, and at the same time, he specifically assigned his top confidant, Sun Jiacheng, to monitor Miao Yongyi alone. He wouldn't let Miao Yongyi join his team until he was sure that Miao Yongyi was safe.

Unexpectedly, Sun Jiacheng discovered the problem today. Miao Yongyi, who never shows his face, appeared when he heard the beggar's voice, which means that he recognizes the beggar's voice. Moreover, the beggar's counter-tracking ability is so strong that he was able to get rid of Sun Jiacheng's tracking. This person must be a professional agent, and he must be a master of tracking.

"Did you disturb that beggar?" Ning Zhiheng asked carefully.

Sun Jiacheng thought about it carefully for a moment, and finally said, "It shouldn't be. I was very far away because I was afraid of waking him up, so I kept a distance. As a result, this person got out of sight. Otherwise, he wouldn't have shaken me off so easily. Also, his anti-tracking movements were very standard. They were routine probing movements. He is a professional agent, one of our colleagues!"

All of this pointed to one thing: Miao Yongyi was problematic, which greatly troubled Ning Zhiheng!

My brother has another identity? This is a partner I've known since childhood. How could he have another identity? If it weren't for my habit of being careful, I would have overlooked it. As an excellent agent, emotional weakness is really too fatal!

But why did Miao Yongyi deliberately want to join the Military Intelligence Investigation Department? Who exactly was Miao Yongyi in contact with? To which side did Miao Yongyi belong?

Japanese? Definitely not! Miao Yongyi has been with me since childhood, and that bond is genuine! His initial fervor for joining the army to serve his country was also genuine!

Moreover, he had no time to contact the Japanese. He and Miao Yongyi had never been separated since childhood, so it was impossible for them to have come into contact with the Japanese during that time. During the year they were separated, Miao Yongyi went to the Northwest Front with the army. The Japanese influence could not reach that far, so it was impossible for him to come into contact with the Japanese. The subsequent history is clearer: the troops marched back to Shanghai to participate in the Battle of Shanghai until he was seriously wounded and sent to Nanshi Hospital, where he was taken to a safe house to recuperate.

Furthermore, his troops and comrades had all fallen on the front lines, and he himself had charged forward desperately, nearly sacrificing himself. If he hadn't found sulfonamide in time to save him, this brother would probably have been dead long ago.

The Central Party Affairs Investigation Bureau? Impossible. The military has always been under the jurisdiction of the Military Intelligence Investigation Bureau. The Central Party Affairs Investigation Bureau would never dare to interfere with the military. Otherwise, not only would the head of the bureau be severely punished, but even the leader would impose severe sanctions on the Central Party Affairs Investigation Bureau.

Military Intelligence Investigation Department? Of course not. Given his position in the Military Intelligence Investigation Department, to put it bluntly, even the Director would have to consider the consequences of doing this. Besides, both of them are well aware of each other's bottom line, so doing this would be redundant.

Moreover, the Chief of Staff knows himself quite well. Even if he were to find someone to monitor him, he would need to find an experienced expert. Miao Yongyi's level is really too low. He has only been around for a little over ten days and has already shown his flaws. He can hardly be considered an expert.

Then there can only be one possibility!

Underground party!

Despite their different paths, this brother had ended up with him. The year they parted ways was when he was on the Northwest Front fighting the Red Army. During that time, they lost contact for a long period of time, and he hadn't received any of Miao Yongyi's communications. Miao Yongyi's explanation was that he was recuperating at a villager's house after being wounded. Now it seems that he was probably not at a villager's house, but at a Red Army hospital!

Another point is that Miao Yongyi and I met by chance at Nanshi Hospital. He certainly didn't expect to meet me beforehand. Afterwards, he suddenly changed his attitude and asked to join the Military Intelligence Investigation Department with me. Someone must have given him instructions. In other words, Miao Yongyi must have contact with the local underground party and can directly act on the instructions of the local underground party. The beggar who suddenly appeared and disappeared was a member of the underground party.

However, these are all just my guesses. To confirm whether Miao Yongyi is a member of the underground party, I must verify it in person. Otherwise, I will not feel at ease. Such a big matter cannot be decided hastily based solely on my feelings.

"Station Chief, I'm afraid your brother's identity is questionable. I think we should verify him more carefully and not be careless!" Sun Jiacheng saw that Ning Zhiheng had been silent for a long time and was afraid that he was hesitant to take action against Miao Yongyi, so he carefully considered his words and gently reminded him.

In his memory, the station chief was always decisive and ruthless, never hesitant. Once he had identified a target, he would act decisively without the slightest hesitation. But now he was in such a dilemma because he couldn't bear to kill Miao Yongyi because of their years of brotherhood.
