Obviously, Yu Xiaohe's "disappearance" should also be part of their plan, otherwise Yu Xiaohe's own mind and behavior pattern may not be so thoughtful.

Chai Yao has also been staring at it, and it is certain that these two people have not had any contact recently, and Dai Tianbao's matter has not caused any sensation for the time being, and it is unknown whether Chai Yao knows about this matter.

However, there was a guess about how they manipulated the dog during the implementation of the plan, and Huo Yan found the answer.

In a video sent back by a colleague squatting, Chai Yao accidentally dropped something on the side of the road, and when he bent down to pick it up, something hanging with a thin red rope slipped down the neckline, which he quickly picked up and stuffed back into the collar.

"This thing!" Huo Yan's sharp eyes suddenly saw clearly what Chai Yao had hidden in his neckline, "Dog whistle!"

"Dog whistle?" Ning Shuyi suddenly said, "I've heard of it before, but I haven't seen the real thing.

It's the kind of whistle that we can barely hear, but dogs can hear, right?"

"yes, that makes sense." Huo Yan thought for a moment, "With this thing, Yu Xiaohe doesn't even need to show up.

As long as he hides somewhere around with the dog in advance, the distance is enough for the dog to hear the sound of the dog whistle.

Chai Yao blew the dog whistle according to Yu Xiaohe's method of training the dog in advance, and when the dog heard it, he would rush out and bite the victim according to the training instructions.

And when the victim was bitten and seriously injured and died, as long as one of the two of them blew the dog whistle again, the dog could quickly return to Yu Xiaohe's side as trained.

So Chai Yao doesn't need to have any direct contact with the dog from beginning to end, and he doesn't even need to be too close to it, so it won't have a particularly strong effect on his allergies.

Yu Xiaohe doesn't need to show up, he has been hiding in the shadows, as long as he is not discovered, it will be difficult for us to find flaws on Chai Yao's side."

Ning Shuyi sighed slowly: "Although I am a little sorry for Dai Tianbao and his wife in saying this, it is really thanks to the contradiction between him and Shi Linli that Shi Linli added fuel and vinegar to the Internet, which made Yu Xiaohe unable to hold his breath and rashly acted.

Otherwise, we don't know how long we will have to toss this case before we can have an eyebrow!"

Two days later, Luo Wei and Qi Tianhua came back, and the two of them spent a little effort and carefully visited some of Chai Yao's past classmates and teachers, and inquired about some of Chai Yao's past experiences and performances when he was studying.

"Shuyi, I said you are really a god! This Chai Yao's situation is not bad at all from your previous analysis!" In the past few days of going out for running, Luo Wei was also tired, but he was very excited, "What Chai Yao's classmates and teachers said to him in the past is what you speculated before!

This guy has not had a good heart since he was a child, his stomach is bad, wilted, and he always talks and acts half-truths, which makes it difficult to guess.

He doesn't do anything that violates discipline directly, but he encourages others to do it, and it's really an increasing trend from light to severe."

Qi Tianhua poured a glass of water and handed it to Luo Wei, asked him to moisten his dry lips, leaned on his side, leaned on Luo Wei's table, and continued for him: "In the information we can grasp, Chai Yao once instigated his table mate in elementary school to steal the watch of the little boy at the front table.

After stealing the watch, the two smashed the glass of the watch, just to see how the cartoon hands of the moon and the sun in the child's watch rotated, and whether they could play with it with their hands.

Later, after being discovered by the teacher, because the watch was taken by the student and the glass was smashed by him, he was approached by his parents to compensate the other party for the money of the watch. Chai Yao was just an onlooker, so he briefly criticized a few words.

Later, the student found out that Chai Yao lied to him that the cartoon hands of the watch had such and such magical functions, but in fact he was simply jealous that the classmate had a relative abroad and gave him such a novel watch that no one else had ever seen."

"When we first inquired with this person about these statements, we thought that Chai Yao was really bad enough when he was a child, but we didn't post it until I asked his middle and high school classmates

Now, this man is really bad."

Luo Wei poured a few sips of water and couldn't help but rush to share their gains: "When he was in junior high school, he saw that one person in the class was not pleasing to the eye, so he deliberately pinched his head and tail, moved flowers and trees, distorted the other party's meaning, and caused the other party to have a conflict with a few gangsters in the school.

In the end, the conflict escalated, and the person was beaten and hospitalized by a group of people, and Chai Yao was also kept on the record because of this incident.

By the time he was in high school, this guy realized that he was over eighteen years old, and he knew that he couldn't be too qualified, and you can't imagine how lacking in virtue he was!

He was jealous that the two boys in the class had a good background, studied well, and were very good-looking, and were especially popular with his classmates, so he deliberately made friends with others, and then showed people that kind of magazine!"

"Which?" Huo Yan didn't understand what Luo Wei meant.

"It's the kind of ...... that people in it can go directly into the bathroom to take a shower," Luo Wei said, "Think about it, it's just such a bloody age, and those two stupid boys are so fascinated that they can't give up, they can't eat and sleep, how can they still have the heart to study!"

Later, his grades plummeted, and those who could have taken the exam would have been admitted to a less-than-ideal school in the end.

But back then, these two people felt that if they let the teachers and parents know that they were thinking about it every day because they read that kind of magazine, they were impetuous and impetuous, so they would have no face to be a person in the future, so they didn't dare to tell others, let alone report Chai Yao, so they would be called a pit for nothing!"

Qi Tianhua nodded: "He hasn't done a single bad thing directly since he was a child, it's basically related to instigation, hiding behind other people's backs to do things.

In addition, from instigating classmates to steal petty in elementary school, to damaging the reputation of others and instigating others to cause personal harm after junior high school, there is basically a clear upward trend in severity, and the tendency to control and destroy others is also more obvious.

By the way, how are you guys doing?"

Ning Shuyi, who was asked, also smiled back at him: "Not only do you have gains, but our gains are not small.

Considering that Chai Yao is cunning and cautious, we speculate that there must be no trace of his contact with Yu Xiaohe in the call records of the past six months.

So we directly took the procedures approved by the above, found the communication company, and through their internal technical authorization, checked the call records for more than half a year, and really found evidence of Chai Yao's contact with Yu Xiaohe."
