Lie in bed at night. Turning it over and over, I can't sleep, thinking about what has happened these days, everything is like a plot, twists and turns are bizarre and weird, and all the strange things point to ten or twenty years ago, my father left home and disappeared at that time, Li Guozhi's daughter-in-law and children were also accidents at that time, and even the Long Po family, Lao Wang's family, Wu Yuhui's family......

Something happened during that time, and several good families have become like this now.

I thought of the three sentences left by Lao Wang before he took his last breath, I already know the reason why I was looking for Li Guozhi, and as for the reason for finding Wu Jinghan's grandfather Wu Baocai, I can also know a rough idea from those diaries.

Wu Baocai should know something, but unfortunately I haven't asked clearly, the person is dead.

Until now, I don't believe that his death was an accident, and of course I don't believe that the deaths of Lao Wang and Hong Jingsheng were accidents.

Thinking of Wu Baocai, I thought of those diaries and the black box he left behind again.

The contents of the diary Wu Jinghan have read it and she told me. The diary basically describes what his grandfather saw and heard when he was a security guard in a pharmaceutical factory and a museum.

According to her description, the Yellow River Pharmaceutical Factory and the Yellow River Museum seem to have a close connection, and even after the closure of the pharmaceutical factory, he was able to go to work in the museum, and he was also the leader of the pharmaceutical factory. Guided to introduce.

I used to suspect this: this pharmaceutical factory is developing and producing drugs for human diseases, and almost all local hospitals have supply and demand relations, especially 20 years ago, the logistics industry was not as developed as it is today, and most of the basic medical equipment and drugs needed for hospitals and health were still provided by local pharmaceutical factories and factories that produce medical equipment.

Maybe something went wrong with the Yellow River Pharmaceutical Factory when it was developing or producing drugs, and it closed its doors – but in any case, how could the pharmaceutical factory have anything to do with the museum?

It's really puzzling.

Black box!

Wu Baocai's words suddenly came to my mind, I accompanied Wu Jinghan home that night, Wu Baocai told Wu Jinghan several times, asking her to keep her parents' relics, that is, the black box.

What's in the black box? What did his parents do back then?

Thinking of these, I suddenly came to the spirit, looking at the phone is already more than ten o'clock, for autumn, this is a time to say whether it is early or not, and it is not finished.

After a moment's hesitation, I put on my clothes and went out.

"Pap-papa-papa"

I had been paying attention, but the knock was still harsh in the quiet of the night.

This point knocks on the door of the girl's dormitory, so that others will definitely think twice, I am a big man, thick-skinned, it doesn't matter, but I have to estimate the feelings of the two girls in the room!

The door squeaked open, and Wu Jinghan leaned out half of her body: "The gospel is here!" You...... What are you doing? ”

The shyness on my face intoxicated me.

"I remember. I'll have to ask you. ”

"Why is it so important that it can't be tomorrow?"

"Yes, yes, but I'm suffocating......"

"Yes...... Is it Brother Dong? Come on in! ”

The voice of Liang Gospel came from the room.

I think it's a little funny, this is Wu Jinghan's dormitory, she let me in, isn't it a bit noisy.

"That'...... Then come in! ”

Wu Jinghan dodged a slit, and when I passed by, she was still pouting and squeezing her eyes at me.

Both of them were wearing nightdresses, and it was obvious that Liang Gospel was wearing Wu Jinghan's clothes, with a slightly smaller number, giving people a feeling of tightness, which made me can't help but take a few more looks.

"Have you seen enough? If you've seen enough, just ask! ”

Wu Jinghan scolded angrily, making me come back to my senses in an instant.

"I ...... I want to ask you about your parents. I hurried straight to the point.

"My parents? How...... Why do you suddenly ask about them? The anger on Wu Jinghan's face was instantly replaced by doubt.

I replied bluntly: "I suspect that the disappearance of your parents back then has something to do with the case we are investigating!"

"What?"

Wu Jinghan sat down on the bed. , talk about the parents.

When her parents disappeared, she was only four or five years old, and it had been almost twenty years since she talked about them, and Wu Jinghan didn't remember much about them.

Wu Jinghan's father is a construction engineer and his mother is a supervisor of a construction company, and the company they work for belongs to the tertiary industry of Shengli Oilfield, and she does not know the specifics, and this company has long ceased to exist.

At that time, it would be good for the villagers to have a job, and Wu Jinghan's parents were also children who were detained as "fighting for qi" in ten miles and eight villages.

In distant memories, his parents always left early and returned late, were busy with work, and seemed to be planning to design a bridge before they disappeared.

It was supposed to be a bridge across the Yellow River, and it was near their village, but unfortunately after her parents mysteriously disappeared, she didn't see a bridge built nearby, and later, the entire construction team disappeared.

……

After listening to Wu Jinghan's story, I had more doubts in my heart.

My dad is a barefoot doctor, and Wu Yuhui's parents are police officers. If her parents are also barefoot doctors or police officers. See, I can accept it in my thinking, and I can connect it with the disappearance of our elders.

But his parents both work for construction companies, which ...... How can these three types of professions be linked together?

Maybe seeing that I was silent, Wu Jinghan asked lightly, "What else do you want to know?"

I suddenly relented and asked her, "The box left by your grandfather has not been opened?"

Wu Jinghan shook his head: "The iron box is very strong, and it is a hidden lock, so it will not be broken...... It's hard to open...... I don't want to destroy my parents' only legacy. ”

After speaking, Wu Jinghan dragged out the box from under the bed and pointed to the dark keyhole on the box.

Dark locks? I subconsciously frowned, and thought of the black key in Wu Yuhui's hand, looking at the appearance of this dark hole, the key must be unusual.

If the contents of the box were known, perhaps the case would have taken a major turn.

Ask Liu Liwei or Zhang Lihai to help tomorrow! They must know a lot of lockpickers, and their gut tells me that there must be something very important hidden in the black box.

Early the next morning, I was awakened by the roar of a car, and when I opened a corner of the curtain, I saw a light truck driving into the yard and turning to the side of Li Guozhi's family home.

No way! I overslept and looked at my phone, it was already half past eight.

Hurriedly put on his clothes and trotted to Li Guozhi's yard.

He was the only one standing at the entrance of the courtyard, and when he saw my embarrassed appearance, he smiled at me.

"Sorry, I'm late......"

"It's all right, it's time to ......," he turned to the truck driver again, "brother, you're only responsible for delivering to your destination!" We'll move the stuff. As he spoke, he took out two boxes of soft China from his pocket and handed them over.
