Zhuo Shaoqing and Zheng Biwan were rushing over to the university campus. They coincided with Wu Tongguang's inference, and Li Qingfeng must have left a very important thing to Professor Zhu.

Zheng Biwan was silently praying in her heart, hoping that Professor Zhu would not have an accident, and Zhuo Shaoqing, Li Qingfeng, and Zheng Biwan had all received help from Professor Zhu back then.

The two of them are both in good shape, and their feet are fast, running all the way from Nanshi to the direction of the university, and it seems that it will not take long to reach the university campus.

Zhuo Shaoqing said: "What do you say it will be?" ”

Zheng Biwan said: "I can't say it well, but if that half of the book is not burned, I'm afraid it can still be launched." ”

"Alas....... thinks that back then, Zheng Biwan was a powerful figure, but now she has become someone else's eagle dog. He had a regretful expression on his face, and he was very indebted.

Zheng Biwan said angrily: "Shut up, what do you know? Who is like you, a person who has no responsibility. ”

"Responsible, you still tell me to be responsible?"

"My whole art industry has been cultivated by the party-state and the 'upper peak', if I don't follow the dog and horse to repay me, can I still be regarded as a human being."

Zhuo Shaoqing intensified and said: "What you said is not wrong, your party-state really does not treat you as a human being, it is nothing more than a dog and a horse." ”

"You!" Zheng Biwan was about to give him a slap.

"If this Tianjin city is liberated by the communist army, what should you do and defend Nanjing?" Zhuo Shaoqing was quite concerned about her.

Zheng Biwan said word for word: "Our army will not lose Tianjin City." ”

"It's hard to say...... It's hard to say, I think, Peking won't drag on for too long. ”

Zheng Biwan pondered for a while, and said gloomily: "If there is really that day, my husband must be very happy, and I will go with him when the time comes, I guess he has waited too long for me." ”

Zhuo Shaoqing asked: "Since your husband wants to see the liberation of Nanjing, why do you try your best to prevent the CCP from obtaining this information?" ”

"You don't understand, you'll never understand what we women think."

Zhuo Shaoqing shrugged, in his opinion, Zheng Biwan and Li Qingfeng were their own masters, and it was really incredible to love and kill each other. In fact, the two of them each stick to their creeds, and they are so strong, they are absolutely unwilling to bow to each other, Zheng Biwan followed Li Qingfeng south, I am afraid that he is also holding him hostage, even if the nervous Li Qingfeng is lucky enough to return to Nanjing and connect with the CCP personnel, she will kill her husband as soon as possible, and she will not hesitate for the sake of the party and the state.

However, until the last moment, she will not do it, because he is her husband.

Thinking of this, Zhuo Shaoqing couldn't help but feel a little sour in his heart.

Zheng Biwan asked, "I have always wanted to ask about one thing. ”

"Don't ask, I won't tell." Zhuo Shaoqing said.

"I haven't asked yet!"

Zhuo Shaoqing said: "I don't know what you want to ask, but I just don't want to answer, it's your business to ask or not, it's my business to answer or not, Lao Tzu is in a bad mood." ”

"Still not in shape!" Zheng Biwan said angrily.

Zhuo Shaoqing was suddenly very disappointed, and said: "Yes, I don't have a positive shape, Li Qingfeng is too upright, too upright, so he was ruined." ”

Zheng Biwan said: "I won't kill you today, but I don't believe that my husband committed suicide." ”

"If you don't believe it, there's no way, anyway, when everything comes out, wait until you see Professor Zhu and see what Li Qingfeng left for him."

"Actually, I know it." Zheng Biwan said.

"Oh? What is it? ”

"The half of the book has been burned, do you know what it was before it burned?"

She continued: "It was a diary. ”

......

"Wutong, I guess that the mother book used to crack the code of the "Guiyan" is a diary." Wu Tongguang suddenly had a flash of inspiration and said to Li Wutong.

Li Wutong quipped: "When is it, Wu Tongguang, half an hour has passed, guess and guess, is there any connection between the cause of Professor Zhu's death and this incident?" ”

At this time, Wu Tongguang was re-investigating the scene, standing in front of the bookshelf in the lounge, looking at the various engineering books on the shelf, he meditated in his heart: "There are so many books on this shelf, some are teaching materials, and some are teaching notes, most of these notes are the professors' own experience, and it has been some time since foreign advanced science and technology were promoted in China. ”

He picked up a notebook and opened it casually, which recorded all kinds of formulas and algorithms, and he seemed to be suddenly thinking about something, and he was fascinated by it.

Li Wutong didn't want to disturb him, but suddenly remembered something and asked, "Don't you think that Lei Yin hid his mother book somewhere in this school?" Oh my God, there are so many books in college, how can we possibly find them? ”

Wu Tongguang came back to his senses and said, "No, this diary is probably in this building. ”

"What?" Li Wutong couldn't believe his ears, Wu Tongguang came to a conclusion so quickly.

Wu Tongguang took out the half-cut book he snatched, the book was already wrinkled, but the three words "Li Mingding" written on the cover, and the poems written in invisible ink were still clear, and he said slowly: "This book was originally a memo of a man with gold wire glasses, you see, although each page of it is blank, but there are blank spaces on its header to fill in the year, month, and day. ”

"So Lei Yin is a person who has a habit of keeping a diary."

Wu Tongguang cast an approving glance at Li Wutong: "Yes, if he doesn't usually have the habit of writing a diary, walking around with a diary during extraordinary times will definitely be unreasonable and suspicious." ”

Li Wutong said: "However, this half of the book is blank. ”

"This notebook is blank, which means that he has not used it for a long time, since he has the habit of remembering things for a long time, where is his last diary?"

"I understand...... Li Wutong thought for a while and said, "No, this doesn't mean that the diary is in this building?" ”

Wu Tongguang said: "If Professor Zhu and Lei Yin have met, then this possibility is very big. ”

Li Wutong said: "If I were Professor Zhu, where would I put this diary?" ”

Wu Tongguang didn't answer, he didn't answer for a while, he continued to look at the bookshelf in this lounge, and he took out the notebook on the shelf, this notebook was very thick, after he opened it, he felt that the handwriting was written by the same person as the last notebook he just looked through. He turned to the title page and saw that it read "Zheng Jiaye", another professor who taught engineering in the school. It seems that this notebook was written by Professor Cheng.

Wu Tongguang's heart moved, and he took out a thick notebook, and the title page was still "Zheng Jiaye".

Wu Tongguang immediately took out all his notebooks, and he called the guards to inquire about Professor Zheng Jiaye's situation.

"Professor Zheng is an old professor in the school, but he seems to have been having some trouble with Professor Zhu...... It can't be regarded as a holiday, it should just be caused by different opinions on knowledge, when I was on duty at the school gate before, I saw the two of them walking together, discussing what issues while walking, and then it seemed that they didn't agree, and Professor Zheng left quickly. ”

Wu Tongguang asked, "What about Professor Zheng now?" ”

"Professor Zheng hasn't come to class for two months, and I heard that he is sick and has taken sick leave. ”

"Sick leave?"

"Yes, in fact, the chief must also know that in the current situation, Nanjing is about to be affected by the war, and many teachers and students are unstable, and there are not many who can persist in teaching and learning." The guard seemed to be excusing Professor Zheng from his sick leave.

Wu Tongguang didn't speak for a while, he thought of a key question, but he didn't figure out where the mystery of the problem was.

Li Wutong looked at Wu Tongguang: "He looks serious, stupid and stupid, very interesting." She and him have established a strong tacit understanding, she knows when Wu Tongguang is concentrating, thinking and reasoning some key issues, so she does not interject, she is also very anxious in her heart, but when she thinks of Wu Tongguang's ability level, she can be full of trust.

Wu Tongguang is the same, he rarely concentrates all his energy on thinking about solving a problem, many problems can be solved on the basis of his little brain, but this time he has to be serious. They don't have much time, he needs to forget about things and me, and only by Li Wutong's side can he enter meditation so confidently.

"Wutong, do you know why I feel that there is something wrong with this scene?" Wu Tongguang suddenly asked.

"I don't know, I'm not a worm in your stomach."

"Because this scene is too normal, it's too normal, so normal that there is no trace of murder at all, this is not the first scene where Professor Zhu was killed!" Wu Tongguang said, loud.
