Guan Zheng and Xu Jiuyan hurriedly ate two bites, then got up and prepared to leave. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Feng Yuan also knew that everyone had important positions, but when he asked what the reason was, he just advised: "Pay attention to safety on the road, be careful, don't worry." ”

Guan Zheng nodded and said, "I know, when Brother Chuan Qiao gets married, you must call me!" ”

Feng Yuan smiled and said, "No problem. ”

Guan Zheng and Xu Jiuyan quickly got into the car, and Xu Jiuyan asked, "What's wrong, what's going on?" ”

"I've got a letter from my family."

Xu Jiuyan was also a little incredible, and said, "What's the matter, it was my house last time, and it's your house this time." What the hell is he going to do? ”

Guan Zheng continued: "I can't say who this person is, but I always feel familiar. ”

"So familiar? What do you mean? ”

Guan Zheng explained: "Don't you think the person who sent the challenge letter is familiar? As you said, first your family, then my family, it can be seen that he knows us very well, and he is also very familiar with the police system, otherwise he would not be so clear about these unsolved cases. ”

Xu Jiuyan instantly had a terrible thought: "Then you mean that this letter is from within us?" ”

Guan Zheng interrupted Xu Jiuyan and said, "This is not what I said! ”

Xu Jiuyan's expression became serious and said, "If this is really the case, it will be troublesome." ”

Guan Zheng nodded and said, "But have you thought about it, if it weren't for this person who got in the way, we wouldn't have solved the Xi Yuanqing case that has been pending for ten years so quickly, and we have to thank him for it." ”

Xu Jiuyan pursed her lips and said, "That's what I said, but could he be the person related to Xi Yuanqing's case?" ”

Guan Zheng decisively rejected the idea: "Impossible. Li Fu's murder case has no chain of interests, and there is no dispute at all. In this case, there are not many people involved, nothing more than Xi Yuanqing's family and the insiders of the case back then, and it is impossible for these people to have the courage to re-investigate the case.

From another point of view, judging from the characteristics of his work, the person who sent the challenge should not be too old, and he did not have any emotional behavior in the process of our re-investigation of the entire Xi Yuanqing case, which is not something that ordinary people can do.

As far as the nature of the challenge is concerned, this is an act of challenging the authority of the police, and he privately executed the murderer of Xi Yuanqing's case, which has a sense of superiority or pride for him, so he should be an extremely confident and rigorous person in his heart. ”

Xu Jiuyan followed Guan Zheng's train of thought and said: "Then you mean that this person does all this for nothing else, just to use himself as a scavenger?" ”

Guan Zheng nodded and said, "That's right, only such a person disdains to use his high IQ to confront our police, so as to achieve the purpose of fighting the police." ”

Xu Jiuyan couldn't help but gasp and said, "Isn't that too scary?" ”

Guan Zheng smiled and said, "What's this?" As long as you don't kill people and set fires, he won't be able to find you, right? ”

Guan Zheng and Xu Jiuyan rushed to the house, and the cordon had been fenced. Guan Zheng stood outside the cordon and asked, "What's the situation?" ”

Li Chongyang shook his head and said, "There is nothing strange, you come in and step on it casually, because there is no trace left." ”

Guan Zheng and Xu Jiuyan got into the cordon, went around in a big circle, and found nothing. Nothing was lost, and there was one more letter.

Guan Zheng took a deep breath and opened the envelope with reverence. Xu Jiuyan asked nervously, "What was written?" ”

Guan Zheng mysteriously unfolded the piece of paper in front of everyone. It's a blank slate!

Xu Jiuyan flipped through the paper several times and said, "What does this mean?" Send a blank piece of paper, a waste of feelings. ”

Lao You took the paper, smelled it, and said, "The smell of potatoes." ”

Xu Jiuyan looked at Lao You in surprise and said, "Your nose is so smart, you can smell it?" ”

Lao You nodded and said, "Of course." The main ingredient of paper is cellulose, and the main ingredient of potatoes is starch, which means that the paper has the taste of grass, but there is also the taste of powder here, so it is easy to distinguish. ”

Xu Jiuyan silently gave a thumbs up and said, "Amazing." ”

Lao You had already taken out the iodine solution and gently smeared it on the paper with a cotton swab, revealing the contents of the paper.

Xu Jiuyan looked at the pattern on the paper, couldn't help but feel a little disappointed, and said, "Give it to Guan Nuo and let her crack it as soon as possible." ”

Guan Zheng nodded and said, "You must tell her as soon as possible." ”

Xu Jiuyan nodded and said, "I see." ”

Li Chongyang walked around the house a few times and said, "Do you want to check it again?" Don't throw anything away. ”

Guan Zheng looked at Li Chongyang a little inexplicably and said, "I've checked it, there shouldn't be anything missing." ”

Li Chongyang nodded and said, "That's good." ”

Guan Zheng exhaled and said, "Almost you guys will leave, the cordon has also been withdrawn for me, and I look depressed." ”

Li Chongyang hurriedly beckoned and said, "Xiao Wang, remove the cordon, you put away the survey box and go downstairs to wait for me." ”

Guan Zheng lay on the sofa and said, "You have worked hard, and you have to toss it so late." Go back and rest early, and I'll be in the bureau tomorrow afternoon. ”

Li Chongyang raised his hand to look at the time and said, "What tomorrow afternoon, it's this afternoon, it's already past twelve o'clock." ”

Guan Zheng glanced at the clock on the wall and said, "Time flies so fast, another day has passed." ”

Li Chongyang had never seen Guan Zheng so depressed, and asked tentatively, "Master Zheng, are you okay?" ”

Guan Zheng shook his head and said with a smile: "It's okay, what can I do?" Before I get back half a day of vacation, you should leave quickly, and don't appear in front of the History Bureau, and don't tell him about the holiday without permission. ”

Li Chongyang nodded with a smile and said, "No problem, then let's go." ”

Guan Zheng was lying on the sofa, cold sweat coming out of his face. Xu Jiuyan went into the kitchen and rummaged through it.

Guan Zheng glanced at the kitchen a few times and said, "Don't harm my Moutai." ”

Xu Jiuyan flipped through it and found a bottle of medicinal wine. Guan Zheng's eyes widened and asked, "You actually put the medicinal wine in the kitchen!" ”

"What's wrong? Is there anything wrong? ”

Guan Zheng swallowed silently and said, "It's easy for you to mislead me like this, what if I accidentally eat it?" ”

"It's okay, this live blood."

Guan Zheng was speechless for a moment and said, "Okay, okay, it's good if you're happy." ”

Xu Jiuyan poured the medicinal wine into her hand and said, "Lift your legs." ”

"Do you think I can do it?"

Xu Jiuyan sighed and said, "Come on, I'll help you." ”

Guan Zheng smiled and said: "It's good to have a daughter-in-law!" ”
