Sewage wells are common supporting equipment on municipal roads. They are usually installed in low-lying areas of a section of road. However, the bridge on the west side of Kangyan Road is over a small river. It is really strange to build a sewage well guarding the river, so this sewage well is
The well is most likely the exit from the tunnel of Yulong Apartment.
That night, Liu Yingying reported the results that Li Kainan saw to everyone.
"Is the information reliable?" Wang Yuanhe fumbled with his stubble.
"When Yue Chen went home, he passed by and noticed something strange." Liu Yingying didn't dare to confirm.
"There is no direction to investigate the case now, but we can keep an eye on it. Chaofei, I'll leave this to you." Wang Yuanhe assigned the task to Wu Chaofei.
"No problem, I'm the best at squatting." Wu Chaofei readily accepted.
Wu Chaofei was a member of the special forces and was best at field operations and squatting. After leaving this matter to him, no one asked about his specific plans.
"By the way, Chaofei, let me tell you the situation of that case." Zhao Xiujie turned to look at Wu Chaofei.
"Oh, I just received a notice from the Gufang Street Police Station, saying that someone from the Crown KTV catering department in Wangfujing, Gufang Street, reported a case and said that a man was caught poisoning food."
"Crown KTV again? Lu Xipu's property." Xiaozhi tapped the keyboard in front of him.
"The suspect was also transferred to our city bureau, as well as the food he poisoned. After testing, the suspected ingredient was arsenic trioxide." Wu Chaofei continued.
"Arsenic trioxide is the main component of arsenic." Shitou added.
"The last time Lu Xipu personally reported the food poisoning death case, was it also arsenic?" Wang Yuanhe confirmed.
"Yes, we also feel that the same person should be responsible. We will interrogate him as soon as possible after the meeting." Wu Chaofei said.
"Eh? The last time we tracked the poisoning suspect wearing a peaked cap based on surveillance, did he disappear in a small park south of Yulong Apartment?" Liu Yingying suddenly thought.
"Yes, yes, you have the impression that it seems to be the small park near your home." Xiaozhi nodded immediately.
"So, the sewage outlet under the bridge on the west side of Kangyan Road is more likely to be an tunnel exit." Liu Yingying emphasized again.
Yue Chen did not participate in this video meeting, but was handling an emergency at school. Gao Xinxin was about to jump off the building.
The last time Gao Xinxin went to the hospital, it was because Gao Xinxin's teacher Liu was in labor, so she asked Yue Chen to come and help temporarily. This time, the incident had nothing to do with Yue Chen, but Gao Xinxin actually asked Yue Chen to come over before she would communicate. In order to reduce the risk of accidents,
Unexpectedly, Yue Chen rushed to school.
As soon as Yue Chen arrived at the campus, he saw fire trucks and police cars surrounding the downstairs of the boys' dormitory.
"What's going on?" Yue Chen squeezed into the crowd to find Huang He.
"Who knows what happened? I also suddenly received a call saying that a student was going to jump off the building. When I got here, I heard him tell you to come over." Huang He looked nervous.
"Now you have seen my charm." After Yue Chen finished speaking, he took two steps forward and came to the front of the crowd.
"Teacher Yue, is that you?" Gao Xinxin's voice came from the dormitory building.
"Ouch! You know how to find a place. The lights are out here. You have to go to the rooftop to study!" Yue Chen shouted upstairs.
Yue Chen's voice startled everyone present. Teachers and students who are familiar with Yue Chen may still barely know that Yue Chen is such a dishonest-looking teacher, but others, including firefighters, police officers, and especially Gao Xinxin
My parents suddenly felt their hearts in their throats.
"Teacher Yue, please stop teasing me, I don't want to live anymore." Gao Xinxin's voice came.
"Then you did this question wrong!" Yue Chen said with a frown.
"Ah?" No one including Gao Xinxin understood.
"You don't want to live anyway, let's do another math problem. Tell me how high the sixth floor is." Yue Chen continued to say something astonishing.
Gao Xinxin: "It is usually considered that one floor is 3 meters, and six floors is about 18 meters."
Yue Chen: "What is the speed of a free falling body after its displacement is eighteen meters?"
Gao Xinxin: "The root number is 2gh. If it is 20 meters, the landing speed is about 20 meters per second, so it should be about 19 meters per second."
"That's right. It seems that I haven't forgotten what I learned last year. Look at this mat. It will probably cushion you for at least a second if you fall on it. Calculate it according to the impulse theorem. How big is your impact?" Yue Chen said.
After finishing, while Gao Xinxin was thinking, he continued: "Oh, yes, if you jump from a height of 1.25 meters, the contact time between the feet and the ground is about 0.25 seconds. What is the impact force?"
Yue Chen's words made everyone at the scene fall silent.
The scene was quiet for two minutes, and Yue Chen said: "A free fall from a height of 1.25 meters, the landing speed is 5 meters per second. According to the impulse theorem, it can be calculated that when you jump from here, the impact you receive when you jump from 1.25 meters
Even if his strength is about the same, he will definitely not die." Yue Chen gave the answer.
"So after you jump off, you will only make your parents more worried, and you will be even less free in the future." Yue Chen still remembers the suffocating love of Gao Xinxin's parents for him.
After another period of silence, Gao Xinxin's voice came from upstairs: "Teacher Yue, can you come up alone?"
Hearing this, Yue Chen also breathed a sigh of relief. Because although the series of data calculations just now were not a big problem, these data were made up by Yue Chen.
"Don't worry, I will definitely bring him down safely." Yue Chen said to Gao's father, Gao's mother and Huang He.
Yue Chen came to the top floor of the dormitory building and saw several firefighters at the entrance to the rooftop. After being told a few words, Yue Chen revealed his head from the rooftop.
"Lao Gao, can I come up?" Yue Chen said with a playful smile.
"Well, can you come up alone?" Gao Xinxin emphasized again.
"No problem." Yue Chen said as he climbed up to the rooftop and closed the skylight of the rooftop with his backhand. This action of Yue Chen undoubtedly increased Gao Xinxin's trust in Yue Chen.
Yue Chen did not approach Gao Xinxin in a hurry, but walked to the edge of the rooftop while keeping a distance from him, looked under the rooftop, and simply sat on the edge of the rooftop.
Yue Chen was a little afraid of heights, but he still tried hard to control his inner fear for the sake of his children, and said to Gao Xinxin: "There is no one here now. Come and tell me what happened."
"Teacher Yue, I'm so confused." Gao Xinxin finally began to express his feelings.
"Are you talking standing up or sitting down?" Yue Chen said, patting the place next to him.
Gao Xinxin hesitated for a moment, then walked over and sat side by side with Yue Chen on the edge of the rooftop, with her feet dangling in the air.
Everyone downstairs was stunned by this scene.
"What the hell is the teacher doing this month? Can't we just press him down?" Gao Xinxin's father said anxiously.
"Dad Gao Xinxin, the method you mentioned can only prevent the child's accident this time. It will also make the child lose a trusted friend. What if the child develops a mental disorder again later? Who will save him? Middle school students, neglect is better than obstruction." Huang He
He immediately stood up for Yue Chen and mercilessly criticized Gao Xinxin's father.
