After putting all the things he bought into his space, Professor Dong ran towards the Public Security Bureau without stopping for a moment, running harder than the 800-meter physical education race he had run in the high school entrance exam that year.

Finally reaching the gate of the Public Security Bureau, Professor Dong paused to catch his breath, steady himself, and then walked in quickly. He went up to the third floor and found a sign that said "Criminal Division Group 2". He knocked on the door, and when he heard the voice of "Come in", he pushed the door open and walked in.

The room was quite large, with about six or seven large desks neatly arranged in pairs facing each other. There was also a single desk in the corner, next to a row of filing cabinets. I guess that single desk was their team leader's desk.

Suihe was sitting at a table where two people were sitting opposite each other, looking down at documents.

Suihe had never been to school and was illiterate. When Xingxing started elementary school, he was placed in a first-grade class. Having a nine-year-old in a class with six- and seven-year-olds was jarring, so Shuishui gave Xingxing extra lessons every night. Seeing this, Guan Huashu suggested Suihe join in the fun. Eventually, studying only at night wasn't enough for him, so he started studying every morning or noon, whenever Shuishui was free and Suihe was home.

Guan Huashu was incredibly kind to Suihe, even though he couldn't explain why. From the second day after moving into Fifth Grandfather's house, when he saw him at work, he couldn't help but be kind to him. Thinking of such a young child, orphaned and growing up alone, Guan Huashu felt incredibly sorry for Suihe. Influenced by him, Professor Dong also grew fond of Suihe, and over time, he began to treat him like his own son.

By the time he arrived at the county office, Suihe had completed all the elementary school courses. He knew the basics of Chinese characters, could read and write, and was even better at math. Suihe was very bright, and even Shuishui had taught him some modern middle school knowledge, which he had mastered quite well. So, now, sitting at a desk and reviewing documents was something Suihe hadn't even imagined a year ago.

When they heard someone coming, everyone looked up at the door. Suihe stood up from his seat as soon as he saw that it was his aunt coming, and asked as he walked, "Why is my aunt here?"

You don't have to speak behind others when you speak here, and everyone in the office can hear what Professor Dong says, and they must listen together.

"He, I just went to the scrap collection station to buy some waste newspapers to cover the side wall of our second-floor balcony. I saw a young man inside the collection station who looked very suspicious. I suspect he's a spy."

Everyone in the office was shocked when Professor Dong said this and gathered around. Suihe asked Second Aunt to sit down for a while while he went to find Lao Cui. Lao Cui and the people from Criminal Investigation Team 4 were interrogating a prisoner in the interrogation room on the first floor.

Professor Dong was a well-known figure in the Public Security Bureau. Everyone knew that Guan Suihe, the specially recruited officer, was a skilled investigator with impressive skills and aloof demeanor. It was said that his exceptional crime-solving skills were the "secret recipe" of his second aunt.

They had never heard of criminal psychology, micro-expression psychology, or criminal psychological profiling. But when Suihe talked about it, they could talk about it endlessly. The most important thing was that they actually thought everything Suihe said was absolutely right.

At first, no one knew who the person who came to see Suihe was, but when they heard Suihe's "Auntie", everyone was like fans meeting their idol. They immediately surrounded Professor Dong and talked to him like eight hundred ducks.

Professor Dong was also a little confused. Why are the people here so enthusiastic? It's abnormally enthusiastic! I'm a little scared.
