It was still raining heavily in Cheongju, and this was the second day in a row, and many streets and alleys were already heavily waterlogged, and passers-by had to roll up their trouser legs and wade through the water.

Ling Shuanghua's location at the moment is a three-story single-family villa in the center of the city, which is the office of the detective agency she bought, which is a newly built high-end residential community with a good drainage system, so naturally there will be no water accumulation.

Sitting across from her were two people, an old man and a young man, who were the two founders of this detective agency, one a retired old policeman and the other a young man who had resigned in order to follow him.

The old policeman's name is Lu Linrui, and the young one is called Kang Mengbin, who is actually Lu Linrui's son-in-law, speaking of which is also a very vulgar story, the young police officer followed the old leader to start a business and rubbed a spark of love with the old leader's daughter, hehe, our life is actually very vulgar, just be happy and sweet.

Lu Linrui took a sip of strong tea, since he was forced by his daughter and son-in-law to quit smoking, he got on this, the tea is the top Longjing before the rain, and it was given to him by his rich boss Ling Shuanghua to play with him.

He said seriously: "We checked all the surveillance videos of Mr. Ling's community, and we didn't see anything strange, Chen Xiaobo left the staff dormitory on his own with a bag, and there was nothing unusual in his performance and expression. ”

Ling Shuanghua sat on the boss's chair, expressionless, and said coldly: "Of course he disappeared after going out, since he didn't appear in the camera at the next intersection, he probably left from the side path." ”

Kang Mengbin thought for a while and said: "Mr. Ling, I think there is another possibility of his surname, that is, he actually appeared in the intersection camera, but we didn't see ......."

Ling Shuanghua was stunned and said, "What do you mean?" ”

Kang Mengbin said seriously: "I suspect that he left by car...... Mr. Ling, you see, after Chen Xiaobo left the community, dozens of cars passed through that intersection within half an hour, and maybe he was in one of the cars at the time. ”

Ling Shuanghua's expression became more and more serious: "So, that guy was really taken away by someone else?!" That person must have come for the 'non-existent classroom', but the question is who it could be? We have been staring at Lu Zhenyu and Huang Fuyuan, we know their whereabouts well, could it be the missing Gu Jiajia or the fugitive Chai Simin? ! ”

The old criminal policeman Lu Linrui lowered his head and thought for a long time and said, "I can only say that there is this possibility...... But maybe the surname is not too big, those two people are now wanted by the police, and they can't protect themselves......"

Ling Shuanghua said with grace: "Let's think about it from another angle, let's say that there is such a person who takes Chen Xiaobo away, then my question is, how did he find Chen Xiaobo?" In fact, Chen Xiaobo pretended to be a security guard and infiltrated this community, but he was still very low-key and secretive, don't look at this guy's honest face, the more this kind of person is, the more difficult it is to be exposed, if it weren't for Lin Wenzhou's fiery eyes, I would have almost been mixed up by him, how did that person find Chen Xiaobo and know that he was related to the 'non-existent classroom'? ”

Lu Linrui said in a deep voice: "Mr. Ling's question is good, I want to ask rhetorically, how did he know that he was looking for you?" ”

Ling Shuanghua shrugged and said, "Wenzhou asked, and he said that he knew from the contractor that I was looking for people from the construction team at that time, so he came to the door." ”

Lu Linrui smiled and said: "It's very simple, then others can also find him through that contractor." ”

Ling Shuanghua's expression changed, and then he gritted his teeth and said, "Find out that contractor immediately!" ”

Kang Mengbin on the side nodded, and suddenly said: "By the way, Mr. Ling, there is still something to report, that Huangfu Yuan, there seems to be some change recently, he seems to have gone to the countryside, and the purpose is unknown." ”

Ling Shuanghua patted the back of the chair and said angrily: "I'm too lazy to play with him!" I hate wearing glasses the most, it's annoying to look at! Straight to him hard! ”

Kang Mengbin and Lu Linrui glanced at each other, they both wiped their sweat, and they really couldn't reason with the eldest lady.

But they still agreed without hesitation, who made her the boss?! Then Kang Mengbin said again: "What about Lu Zhenyu?" He has been following Ding Hui, do you want to take action? ”

Ling Shuanghua thought for a moment, waved his hand and said, "You can wait a little longer to see what he wants to do." ”

The two also knew that the eldest lady never managed her surname when she did things, and she said that if she wanted to let it go, just let it go, don't argue with her, it's boring.

After Ling Shuanghua finished speaking, he was about to get up and leave, and suddenly Kang Mengbin said again: "Oh, Mr. Ling has one more thing, I almost forgot to report it, that is, about the background of Chen Guangzhou, I discovered a big secret, Chen Guangzhou's father is called Chen Aiguo, in the early years he was a technician of the construction team, responsible for surveying and exploration work, and he has some prestige in the construction team, after all, intellectuals." ”

Ling Shuanghua was stunned for a moment, and then Kang Mengbin continued: "We looked through a lot of information, and finally found that Chen Aiguo's work record was that he joined our Cheongju No. 1 Construction Company as a technician, and then disappeared in 1981, and the last clue about him was that he participated in the construction of the Cheongju University Knowledge Building. ”

Ling Shuanghua's breathing became heavier and heavier, his face was very solemn, and he even asked a little nervously: "That Guangzhou father turned out to be a technician of the construction team back then...... It's really ......."

Over there, Kang Mengbin nodded and continued: "Therefore, we have reason to speculate that Chen Guangzhou's father, Chen Aiguo, was also one of the seven workers who disappeared that year, which means that the contractor did not say it accurately enough, in fact, it was not seven workers, but a technician and six workers......"

Ling Shuanghua's face turned pale, which made Kang Mengbin very puzzled, although this was also explosive news, but it would not scare Mr. Ling like this......

How could he know that Miss Ling actually had only one thought on her mental side at this moment, and that was: This is the end, the bet is lost! That big pervert is actually right, Chen Guangzhou really has a deep relationship with the 'non-existent classroom', and now he can't protect himself......

Suddenly, there was thunder outside, and Lu Linrui's old voice muttered: "It's really strange, it's been a few days, why does this rain keep raining?!" ”

In the rental room, Chen Xiaobo was taken aback by the thunder outside the window.

The shadow came to see him again today, and the dark green umbrella was still in the doorway, dripping water.

Seeing his unproductive appearance, the shadow shook his head again and again: "Yesterday you said that your brother's last letter was a little late, and I thought about it for a day, and I wanted to ask you if there were any other strange things besides this?" ”

Chen Xiaobo hurriedly came back to his senses, and thought hard for a long time and said: "There is nothing strange about it, by the way, it is the last letter of my brother you mentioned just now, which is a little strange." ”

The shadow's eyes suddenly lit up and said, "What's strange? As I said earlier, the delay in delivery may also be due to the backward postal system at that time in '81. ”

Chen Xiaobo said seriously: "It's not a matter of time, the strange thing I said is about the person who sent the letter, I remembered, it doesn't seem to be from the post office, I didn't wear the green coat, just a young man in a white shirt, he looks like an intellectual young man, when he gave the letter to my mother, he also bowed hard, the bow is very deep, very polite, my mother has always said that the young man is really polite, in the end, intellectuals ......"

The shadow's face became more and more excited, he/she stood up and paced back and forth in the room, and then slapped the table and said excitedly: "Quick, seriously recall, what is written in that letter!" ”

Chen Xiaobo sighed, then frowned and thought for a while, before he said: "This classmate, you are too embarrassed for me, it's been more than 30 years, I really can't remember, probably just a little impression, that is, my father left early, let me take care of my mother in the future, do my filial piety, there is no right thing in the field, and send back two hundred yuan, saying that it is for me to marry my daughter-in-law, and also said, don't just look at the appearance of a daughter-in-law, be good-hearted." ”

The shadow listened very carefully, and only said after a long time: "Mr. Chen, I probably listened to it, why do you have a very strange feeling, do you say that letter is a bit like your brother's suicide note?" ”

As soon as he/she reminded him/her, Chen Xiaobo's whole body was excited, and he was dumbfounded: "You said that my brother is a suicide note?" He certainly didn't say he was going to die in his letter, I remember it very well. ”

The shadow took a deep breath, and then said word by word: "Because if you say it, I'm afraid this letter won't be delivered, but between the lines he is clearly explaining the aftermath, it seems that my speculation yesterday was wrong, it's not that the postal system was delayed, but that this letter was originally a late suicide note, and when you saw that letter, your brother was no longer alive!" ”

At this time, a flash of lightning streaked across the sky, illuminating the side face of the shadow, and Chen Xiaobo suddenly found that his/her eyes were so terrifying......

Chen Xiaobo trembled and said, "Brother I knew that I was going to die at that time? So wrote a suicide note? ”

The shadow nodded, he/she silently walked to the window, looked at the heavy rain outside the window, and said coldly: "It seems that we were all wrong before, the 'non-existent classroom' is probably not as simple as imagined......"

Chen Xiaobo shook his head again and again and said: "I don't understand, I just want to know where my brother's body is, I want to live to see people die, I want to see the corpse......"

The shadow said lightly: "Don't worry, I understand your feelings, but I'm afraid we need to do another thing first, maybe we can find your brother and the location of that mysterious classroom." ”

Chen Xiaobo immediately said: "Okay, you say, I'm willing to do anything!" ”

The shadow nodded, "It's easy, I want you to find the original manuscript of the last letter your brother gave you, and besides, I'll collect the other six letters...... I firmly believe that the other six suicide notes must exist......"

Suddenly, there was another thunderclap outside the window.

The shadow looked at it and said to himself, "Why does this rain keep raining?!" (To be continued.) )
