At nine o'clock in the morning, there was a group of young men and women playing skateboards and some old people exercising in People's Square. This is not a very good place to exercise, because the square is surrounded by a turntable-shaped road with dense traffic and even frequent congestion, and the exhaust emissions can be imagined. But this is a prosperous area in the city, surrounded by old residential areas. The layout at that time did not take into account the leisure and entertainment of the crowd. These people had no place to go and could only exercise and relax in this square surrounded by exhaust gas. Liao Fei came here as early as 8:30. He had been sitting in a coffee shop on the side of the road, looking at the scenery and pedestrians outside through the bright window. His eyes scanned all the tall buildings around him, staring at any clue. Liao Fei remembered all the vehicles and pedestrians parked on the roadside one by one. As long as you close your eyes, an image will be generated in your mind, and the position of everyone and the vehicle will be exactly the same. After drinking a cup of coffee, Liao Fei came out of the store and came to the square. While doing chest enlargement exercises, he walked around the square, mainly looking at places that couldn't be seen in the coffee shop. Pedestrians and vehicles on the roadside all looked normal, nothing suspicious at all. The group of young people playing skateboards seemed to have known each other for a long time. They chatted and slapped each other freely without any sense of unfamiliarity. It¡¯s even harder to tell which people are new members, excluding the possibility of someone joining temporarily. Of course, agents are humans too, not gods. Even if their eyes are like scanners and their brains are like high-speed computers, if the opponent is the kind of player who has won an Oscar, not only will they look like ordinary people, but they can also quickly get along with them. , so that knowing each other for a minute was like knowing each other for decades. Liao Fei had no choice but to admit that he was not capable enough. At 9:10, an old woman in her 60s came from a distance. She was dressed in ordinary clothes and her hair was covered with silver threads. She walked slowly to the square and nodded to the old people exercising. Liao Fei glanced at her, then withdrew his gaze and continued to watch the young man skateboarding. ¡°These young people are already very familiar with skateboarding. One moment they will do a piggy jump, and the next moment they will lift the board into the air, flip the board and so on. It seems quite interesting. The old woman mingled with the elderly and began to exercise. There is no interaction between the two in terms of sunshine and action. At 9:20, Liao Fei walked towards the center of the square. There was a huge statue in the center. It was the statue of an old leader waving at the square. It was affectionately known as the place where xx took taxis by the people in the city. The old woman also finished her exercise at this time and walked towards the center. The two happened to meet head-on, but they did not look at each other, but looked behind each other. When it was confirmed that no one was following the two of them, Liao Fei rubbed his face, as if he hadn't woken up, and the old woman arranged her hair. The two told each other through actions that no one was following them behind them, and no one was paying attention to them from a distance. Liao Fei walked around the group without stopping in the square and walked towards a nearby restaurant to have breakfast. The old woman didn¡¯t stop and walked towards the other side.
