"Xiyan, why aren't you sleeping yet?" Meng Fanxing opened his sleepy eyes and got up. When he saw that the bedside lamp was still on, Lu Xiyan was sitting next to him, his eyes were open, motionless.

"I can't figure it out." Lu Xiyan said.

"What's the matter?"

"You don't understand what happened in my doctoral thesis. You can sleep. I'll think about it for a while. Anyway, I've got on the boat every day and I have nothing to do, so I just slept with a quilt." Lu Xiyan smiled.

"Don't think too late, I'll sleep first, I'm so sleepy..." Meng Fanxing nodded. The things in Lu Xiyan's thesis were indeed a bit more profound for her. She didn't understand it after she said it. After a while, she fell asleep again.

If the "mission" was not important, he really wanted to solve the tail of Sun Yanan before going to Hong Kong, so he could only give up temporarily.

His motivation and timing for assassination were very clever, and it seemed that he had carefully chosen it. Otherwise, why would he not assassinate early or later, but chose at that time?

Wu Tuzi made a "dark flower" on the black market. He bought his own life. He would be careful when he got the news. According to the principle, choosing to assassinate at this time should be the most difficult.

If he had planned it, he should have taken action while he was unprepared. As for the motive for murder, it seemed reasonable, but it was not very similar to his past assassination operations.

Although he saved Takeuchi Yuko, he did not do anything for the Japanese. The so-called "traitor" should understand this truth if someone with a little ability to identify.

If Sun Yanan is an ordinary person, it may be difficult to tell, but he is the leader of the action group, and this behavior itself is an abnormality.

Then there is his accent, of course, it may also be his intentional disguise, but his identity can be found, so his disguise is meaningful?

After escaping from prison, he lurked back to the hospital and assassinated himself again. He seemed to be persistent and vowed to kill the "treacherous" but he was an agent, how could he act so uneasy?

Also, he was the helper who attracted Tang Jin's attention at Old Ximen. Is Ah Hui still not sure about it now? If so, it would be fine. If not, who would be?

You can't ignore this important clue just because Ah Hui is dead.

Tang Jin closed the case for Ah Hui because he was afraid that he would continue to investigate and who would involve someone, or did he not want to be entangled in the case of "Sun Yanan"?

What is certain is that "Sun Yanan" escaped from prison was a trap set by Tang Jin, which made him desperate. He was definitely not as afraid of death as he appeared on the surface.

He must have hidden some unknown secrets.

Also, the four people who died in the first assassination were all told by "Sun Yanan", and the statutes did not conduct in-depth investigations at the time.

These four people are indeed on the list of "Sun Yanan" anti-traitor group, but if the names are correct, it does not mean that the person is that person.

The more I think about it, the more I feel something is wrong.

"Sun Yanan" has a big problem. He even thought that this person might not be real Sun Yanan, but could be replaced by another person.

Didn’t he also disguised himself as a “military advisor” and ordered the entire “iron-blooded anti-traitor group”. Has no one else found any flaws except those who are informed?

But he had the cooperation of Tan Si and others. The people below met only a handful of times. It was normal for them to know in depth.

The action team members who were with Sun Yanan were together day and night, and it was probably difficult to replace someone.

"Sun Yanan" also involves the mysterious list held by the "military advisor". What exactly the people on it do is unknown.

But one thing is certain, this is definitely a big plan planned by the "military advisor". The plan is not only the present, but also the future.

It is unknown what this plan is now. Maybe Chu Ze knows something, or maybe he doesn't know either. The "military advisor" died too suddenly, and many secrets were brought to the ground with his death.

A detailed and thorough investigation of "Sun Yanan" must be conducted again, and then the investigation was started from his dead men, and Lu Xiyan decided.

The "Iron Blood Anti-Traits Group" just entered hibernation time, but it could not make everyone do nothing. It is not a good thing to be too idle, so they won't find anything to do.

As soon as the sky was dawn, Lu Xiyan called Yan Lei into the study and explained the problems he had thought about all night to him one by one, investigating the direction and the suspect.

"Does sir suspect that Sun Yanan was thrown away?" Yan Lei was shocked after hearing this.

"I can't give you an accurate answer now. Everything will be waiting for the next investigation results of you and Hanjie. What I want is evidence." Lu Xiyan said.

"This Sun Yanan does have many unreasonable explanations. If you don't think about it carefully, it will be easy for people to ignore it." Yan Lei nodded.

"There is no big loophole in the thinking logic of normal people, but we cannot look at problems with normal people's thinking, otherwise we will fall into the situation designed by the enemy for us." Lu Xiyan said.

"I understand, I will tell my fifth brother to secretly investigate Sun Yanan and his men's actions in Shanghai." Yan Lei nodded.

"Tell Hanjie, be careful." Lu Xiyan instructed.

"clear."

"By the way, don't tell anyone about Lao Ma's affairs. Just know about Han Jie." Lu Xiyan ordered.

"Don't you tell me about my second brother, my third brother and others?" Yan Lei was stunned.

"Let me explain to them later." Lu Xiyan said.

"good."

Lu Xiyan and Meng Fanxing did not carry many gifts, including two leather boxes, one big and one small. The boxes contained some clothes and books, as well as Lu Xiyan's doctoral thesis draft.

There is also some food, carried by Ah Xiang.

Three people and two cars arrived at the dock at around nine o'clock.

The people on the dock were shaking. After Lu Xiyan and the other two got out of the car, Ma Xiaowu and Yan Lei lifted the salute from the trunk of the car and followed behind the three of them.

They bought first class cabins or suites, so they naturally didn't need to line up to check tickets. However, the mail ship was parked in the middle of the river and needed to take a barge before boarding.

The ticket checking time has not yet come, so I can only find a place to wait for the moment.

Didi...

A familiar car motor sound suddenly sounded behind him. It was Tang Jin's car. Lu Xiyan turned his head and saw Tang Jin and Qi Huan rushing towards them in the crowd.

"Old Lu, I'm rushing to catch up, finally getting there." Tang Jin reached out and wiped the sweat stains on his forehead.

"Brother Tang, didn't you agree not to send me a gift? I just went to Hong Kong for a vacation and came back after the New Year." Lu Xiyan said.

"Old Lu, let me speak with you." Tang Jin lowered his head slightly and said softly.

"What's the matter, so mysterious?"

The two found a slightly empty space on the dock. Tang Jin handed Lu Xiyan a cigarette, lit it, took a sip and said, "Sun Yanan has a problem."

"Isn't this matter over?" Lu Xiyan said in surprise. Besides, this was originally a consensus between the two.

"I mean, this kid's identity, I made an appointment with Lu Jinshi to talk to him about this tonight." Tang Jin said with great thoughts.

"Identity, what's the problem with his identity?"

"Sun Yanan was sent to Shanghai to perform a mission. According to the rules, once he lost contact, he must have an emergency joint plan. What he left was a watch and a codeword. The time and codeword on the watch must be matched at the same time to determine the other party's identity." Tang Jin said, "The watch is bad, but the time on the above is not fixed, but it must be half an hour earlier than the joint time. I don't need to say the codeword, it also revolves around the watch."

"What did you do when you tell me this?"

"I think that only you can help me with this matter." Tang Jin said, "After you were assassinated by Sun Yanan, in order to verify his identity, I sent a secret telegram to Boss Dai. The method and tokens of the connector were transferred to my hands. On Ah Hui's side, I sent someone to take over the head, but I ordered someone to take another watch, and the time on the watch had not been adjusted."

"Not connected?"

"No, I'll follow it. Ah Hui admitted his identity, but did not give much information." Tang Jin said.

"Then it's strange. Since such a strict joint plan was established, why would Ah Hui admit it?" Lu Xiyan frowned.

"Ah Hui is dead, and there is no way to verify it now. Maybe Ah Hui doesn't know the secret of the time of the watch." Tang Jin said, "It was not until Lu Jinshi sent someone to find me and said that Sun Yanan did not trust them. I asked if there was a way to gain his trust, and I thought of the joint token watch."

"Did Sun Yanan, like Ah Hui, not notice the time on the watch?"

"I can't be sure, after all, when will Lu Jinshi show Sun Yanan when he takes the watch? If the time on the watch happens to be..."

"The probability of this is extremely low, right?" Lu Xiyan shook his head.

"Yes, I also hope my guess is wrong, but this may be just my wishful thinking." Tang Jin's expression was a little sinister.

"What do you want to do?" Lu Xiyan asked.

"I don't know, Lu Jinshi probably believed Sun Yanan. If this is the case, they would be in danger of being exposed." Tang Jin said.

"If Sun Yanan really has an unknown identity, who is most likely to be?"

"The Japanese spy." Tang Jin blurted out without thinking about it.

"How should Sun Yanan explain his identity as a person in the Iron Blood Anti-Traitor Group in the past?"

"This..." Tang Jin was stunned, "Didn't the military advisor disclose some information to you?"

"I am just a contact person between you and him. At most, he trusts me and will not be detrimental to him, but he will not tell me such a confidential matter, especially since my relationship with you is closer." Lu Xiyan said.

"If Sun Yanan is the military advisor undercover in the Military Control Commission, then he does not need to arrange for him to assassinate you, unless there is another plan." Tang Jin analyzed.

"Brother Tang, what do you doubt?"

"Old Lu, I dare not say, but is there any possibility that the real Sun Yanan has fallen into the hands of the Japanese or has died, and this Sun Yanan is simply a fake by another person." Tang Jinshi said in a shocking way.

Lu Xiyan narrowed his eyes slightly and faced the vast Huangpu River. He also considered this question for one night, and the answers were basically the same.

"If this is the case, then the Japanese must have done a lot of things. They will never act rashly at the moment. Lu Jinshi and the others should not be in danger." Lu Xiyan said.

"Let's go long?" A cold light flashed in Tang Jin's eyes.

"The best thing is, no one can tell. The more people know the secret, it's not a secret." Lu Xiyan said.
