However, the three aunts are not so lucky.

Although Gu Qingcheng is their niece.

But after all, it's not that close, and it would be rude to ask.

Finally, Gu Qingcheng decided to keep the eldest, the third, the fifth, and the eighth brother with him.

The question is, since all four children look different, it will be easier to take care of them and avoid making mistakes when feeding them.

The second, fourth, sixth and seventh children were taken care of by Lu's mother.

This is finalized. Gu Qingcheng actually has another idea behind this.

It is already 1976, and in another five months it will be 1977.

At the end of 1977, she could take the college entrance examination. With her ability to get into a 211 university in the future, I believe it would not be difficult for her to pass.

When she goes to college, Lu Shiyan will find an opportunity to transfer her back, and then their family can stay in Jiang City forever.

Everyone chatted for a while, and when Lu's mother saw that it was getting late, she quickly stood up and said she was going to cook.

The three aunts stood up and went to help. Gu Qingcheng had no reason to sit still, so he naturally followed.

As a result, before she had taken a few steps, Mother Lu asked her to sit down.

"Qingcheng, just leave the cooking to us."

Gu Qingcheng, who had just walked out the door: ...

I was "invited" back by my three aunts.

…

Half an hour later, Mother Lu had almost finished cooking the dishes.

Coincidentally, the group of people who went out to build their connections came back one after another.

Lu Shiyan walked over with a gloomy face, but the moment he saw Gu Qingcheng, he smiled again.

"young married woman……"

"Lu Shiyan!" Gu Qingcheng did not ask about the progress of the matter. At this time, he just needed to give them support.

I believe he can handle things.

"Are you tired?"

The two of them sat on the sofa holding hands.

“Not tired.”

Instead, Lu Shiyan took the initiative to report the progress of the matter to Gu Qingcheng.

She took out the list in her hand and handed it to Gu Qingcheng: "I got it."

Gu Qingcheng glanced around. The list was dozens of pages long, with nearly a hundred names on each page.

That’s a screening scope of several thousand people!

Lu Shiyan said, "Wife, these are the names of workers in several nearby steel mills. They may have been exposed to carbon monoxide. If you have some connections, it won't be difficult to get them."

"I plan to compare these names with the names of those who attended the children's full-month banquet that day. If I can find two identical names at the same time, they will be the suspects."

This method does work, but it also has loopholes.

Gu Qingcheng raised his doubts: "What if it is a relative or friend of the suspect who works in the steel mill? It would be difficult for the names on the two lists to overlap, right?"

Li Jiabing spoke at this time.

He also took out a series of names and said, "This is the relationship of the people who came to the banquet that day."

Not to be outdone, Li Jiahuan took out a list and said, "This is their friendship."

Li Jiadong: "This is a list of people they might have come into contact with."

Gu Qingcheng: ...

Hundreds of papers were thrown on the table. After Gu Qingcheng saw them, his eyes twitched wildly.

No, this method is effective, but it is too difficult to search!

Just reading these names from beginning to end would probably make you dumbfounded!

Can this still find the murderer?

Gu Qingcheng expressed deep doubts and worries.

Mr. Lu said, "I just contacted several of the family's servants. They can screen out a group of people. The work pressure will not be so great. Let's divide the work and we will definitely find the suspect within three days."

The three uncles of the Li family nodded, and even Mr. Li and Mrs. Li expressed their willingness to contribute.

Many hands make light work.

That's the truth.

But for a moment she felt a little sad.

The Lu and Li families already have very complete networks of relationships in this era. Even under such circumstances, with so many people working together, the result can only be reduced to this range.

How helpless would so many other powerless people be if they encountered such a thing...

Gu Qingcheng sighed.

At this time, 520 is online again.

520: [Host, host, what are you thinking about? ]

There was a mechanical sound coming from inside the body.

Gu Qingcheng told 520 truthfully what he was thinking.

520 thought it was something else: [Host, are you bothered by this? ]

Gu Qingcheng nodded: [Yeah, you didn't see it. I roughly counted the names of tens of thousands of people on the table just now. Even if we divide it among ten people, each person will have a workload of thousands of copies. Wouldn't it be hard on the eyes? ]

[And if you encounter a duplicate name... the workload will be even greater. ]

As Gu Qingcheng was talking, a flash of thought passed through his mind.

When she was in Tongcheng before, she was looking for the scumbag who had cheated on Li Shaoyuan, and it was 520 that helped her search.

Maybe I can help this time!

Gu Qingcheng's eyes flashed with a smile, and he quickly asked: [520, do you have any tricks? ]

520 smiled; [It is said that if there is a problem, look for the system. Host, just leave this to me. ]

It promised, "What I am best at is big data search. Host, when the time comes, you only need to bring the list of names to the automatic scanning room on the second floor of the space. After I scan it, I can give you the relationship chain right away."

Doesn’t this solve everything?

Gu Qingcheng nodded and said, "It has to be you!"

A huge stone in my heart was lifted, and a smile appeared at the corner of my lips.

Lu Shiyan had been sitting next to Gu Qingcheng. When he suddenly saw her reaction, he felt a little worried.

"Wife, why are you suddenly smiling so happily?" He had a sullen face just now.

Gu Qingcheng was pulled back and subconsciously stopped smiling. She looked around. Fortunately, no one else noticed her coming here.

She cleared her throat, put her arms around Lu Shiyan's waist, and whispered in his ear.

"It just occurred to me that there are shortcuts for automatic scanning and automatic searching in the space."

Lu Shiyan's eyes also lit up.

"When the time comes, we just need to take the entire list into the space and scan it. The results will be available in a few minutes."

"Wouldn't this greatly improve efficiency?"

Two people were whispering here, and in the eyes of others, they were just a couple flirting.

The three uncles of the Li family said that it was simply unbearable to watch.
