Professor Dong isn't particularly gifted at criminal investigation. It's simply because she's watched so many modern films, both ancient and modern, both Chinese and foreign, that she's been drawn to them. She's been interested in two things since she was little: studying history and solving crimes. These two interests might seem incompatible, but she's managed to cultivate both without interfering with one another.

After Guan Laotou was confused, Suihe began to test him to see what he valued. First, he told him about the current situation of his family after he was captured, and how pitiful it was. He also said that the wives wanted to separate and no one would take care of Guan Laotou, but Guan Laotou did not react too strongly after hearing it.

Well, don't expect a man who can prepare explosives to kill an entire county to have much sympathy, even towards his spouse with whom he has slept for decades.

If we start with Sun Baodong, Old Man Guan will definitely not be shaken. At present, it seems that the only people who can shake him are Guan Dashan and Guan Jiang. Suihe decides to start from here.

Old Man Guan was actually a loving elder who loved his children and grandchildren. He was incredibly kind to his sons, especially his eldest son, Guan Dashan, and his eldest grandson, Guan Jiang. He knew full well that with the witness Zhang Zhiqing and the physical evidence on the mountain, he was doomed to die whether he turned himself in or not. So he kept holding on to the crime, but arresting his sons and grandsons was definitely not an option.

At this time, hypnosis already existed in China, but Professor Dong did not know how to do it.

As for Sun Baodong, the surveillance personnel confirmed that he worked at a scrap collection station and no one was at home. Lao Cui, along with three plainclothes officers from Group 2, broke into Sun Baodong's home.

Sun Baodong used to live and eat in a dormitory at the machinery factory. But when he was transferred to the scrap recycling station, he lost the dormitory and now rents a house not far from the station.

The main house was occupied by the whole family, and he rented a side room for two dollars a month.

Lao Cui and his men arrived at the side room of the residential building. The owner and his family had already been called away by the neighborhood office under some pretext, leaving no one home. The plainclothes officers first checked, and Lao Cui spotted two sunflower seeds placed near the door lock. If the door was moved, the seeds would fall to the ground. Lao Cui picked them up and put them in his pocket, then asked his men to unlock the door. Everyone in their bureau had some unique skills; lock picking was just a necessary skill.

I unlocked the door and checked again, making sure there were no signs before entering. The room was simply furnished: a single wooden bed, a wardrobe, a shelf with two plates and two bowls on it. A washbasin rested on a basin stand with a towel draped over it. There was also a small table and chairs, with two teacups and a teapot on the table. In the corner was a stove with a small aluminum pot on top.

The entire room was simple, and a glance at it revealed something. But Professor Dong once said that sometimes, the simpler something is, the more complex it becomes. Old Cui was now completely convinced by Professor Dong. Based on the psychological profile Professor Dong had drawn up at the police station after their first meeting, he felt that this room was not simple.

Professor Dong's words at the time were that based on the man's extremely vigilant and sensitive behavior, there must be something near his home or workplace. The reason he chose home and workplace was because someone so vigilant could spend so much time in these two places, suggesting they were places that gave him a sense of security. Given that sense of security, it made sense that the item would be placed there in the safest place.

In other words, anyone who hides something will put it in a place they feel is safe. However, Sun Baodong is a very sensitive person, and his safe houses are only two places: home and work.
