Professor Dong was not modest either. She had participated in many professional exchange meetings at home and abroad, of course, all of them were history-related. Although this was her first time to attend a criminal investigation meeting, they were basically the same, so it would not make us, the old criminal investigators with many years of experience in "investigating cases", feel nervous.

She is not afraid of being exposed because she really has something in her belly.

She summarized the crime-solving methods that were useful in this era, combined them with history, and spoke of them in a way that Director Jiang could accept.

In 1930, Professor Lin Ji, the founder of modern forensic medicine, established the first forensic medicine teaching and research department at Peking University Medical College.

It was not until the Northeast Public Security Bureau was established in the Northeast Liberated Area in 1948 that the ten-finger fingerprint method was used to solve cases.

Professor Dong knows that those ten years were a period of severe damage to domestic criminal science and technology. This is why she is now willing to take risks to spread the limited professional knowledge she has. She hopes that public security colleagues can master more and more. Even if the chaos during those ten years was caused by human intervention, the people's police will be able to use better means to protect the public and strike down criminals steadily, accurately and ruthlessly, so that they will be afraid to commit crimes and not be able to take advantage of the opportunities.

Director Jiang followed and listened attentively, nodding occasionally, or following the clues to think about what he would do if the case was his own.

The more Director Jiang listened, the more he felt his sister-in-law was a treasure, a real treasure. She wasn't very educated, but she was always able to speak eloquently. She hadn't been to many places, but she could always use rich language to describe them and make others feel as if they were there.

In the past, Director Jiang would not believe it when others told him about such a person, but when he met his brother's wife today, he understood. This might be what is called gifted talent.

Time slipped into the night as they chatted animatedly. Since Director Jiang wasn't allowed to return to Old Cui's dorm alone, they decided to stay there, sharing a bed with him. The happy young man was so excited that he was busy tidying up the room. Anyone who didn't know him would think he was up to some good news.

The next day, Director Jiang and his team set off to return to the province. There was a lot of work piled up in the unit in the past few days that needed them to go back and complete.

Before leaving, Director Jiang told Suihe Laoshi with a look of reluctance that he should wait for the transfer order at the unit, and he would go back to arrange accommodation in advance.

After seeing Director Jiang off, Guan Huashu took advantage of the time difference to ship a large batch of goods to the gang leader. The gang leader was in urgent need of goods recently and didn't know where to find Guan Huashu.

The autumn harvest was approaching, and people were not stingy at this time, knowing that if they exhausted themselves, they would be doomed. Therefore, the streets managed by the black boss sold all the food and non-staple food they could. The black boss followed Guan Huashu's instructions and did not raise prices when it was not necessary, so that he could sell more to the villagers, so that they could have more food and have more energy for the autumn harvest.

After selling food and other items to the gang leader, Guan Huashu thought about it and went to several family compounds "downline" to express his condolences and listen to the new market feedback and the latest gossip.

It's lonely at the top, and sometimes you have to get among the people. It is very important to keep abreast of the public's needs and information.

Everyone who needed to move around had moved around, and it was time for Guan Huashu to return to the village to oversee the autumn harvest. He wouldn't let Professor Dong go back to the village because the harvest was too tiring. Before he traveled through time, let alone letting Professor Dong go to the fields to harvest wheat, he would only let her cook a meal on special occasions, such as when the nanny was on break. Now that he traveled through time and didn't have to work, the two of them were always together, and their relationship was growing deeper. Guan Huashu couldn't let his wife go through this hardship.
