When Ye Guojin was questioning, a colleague was making a note on the side.

"When was the last time you saw Wang Jianguo?"

Old Man Wang said a date without thinking.

Mrs. Wang continued: "That was the day when we took the train to the imperial capital by Jianguo, and we sent him on the train and watched the ......train drive away."

The world is unpredictable.

They thought it was a good thing that their son was transferred to the machinery factory in the imperial capital.

In the eyes of the old couple of them, that is Feihuang Tengda, pointing to the day when they will return to their hometown and glorify their ancestors.

After the package was delivered to the household, the old couple worked hard, thinking of saving more money and subsidizing their sons to raise grandchildren in the future.

"You haven't seen each other since, and you haven't called?"

Old Man Wang regretted thinking that it would be nice if they made a phone call at that time.

Although it is not convenient for them to answer the phone, they can still call if they really want to call.

Their reply to Wang Jianguo was ghostwritten by someone else.

"We wrote in the letter, why don't you call? The reply said that it was because he was busy with work, the factory was big, there were many employees, and there were few telephones, and he was an advanced employee and had to let others. ”

Looking back now, it seems that everything before was already foreshadowed.

If it were another parent, they might have come up with a plan to see their son after he didn't come home, or if he hadn't corresponded.

Of course, this is also the genius of An Heping.

In his letter, he described his life so beautifully, and it was perfectly close to the vision of Wang Jianguo's parents.

Family letters and pension money must be An Heping's reassurance to the elderly parents.

How could the honest Wang Jianguo's parents think that the person who wrote the letter was no longer their son?

Ye Linlang has been accompanying Ye Guojin to make notes for Wang Jianguo's parents.

Although Wang Jianguo's parents are honest farmers, they are also quite sensible, and they should cooperate with the investigation.

After making the record, Ye Guojin considered that the old couple came in the dust, so he arranged for someone to take the old couple to the guest house next to them.

"Linlang, Wang Jianguo compared the DNA data with his parents, when will the results come out?"

Ye Linlang synthesized the current timeliness and said in a low voice: "With the manpower and speed on your side, it may take about three days." ”

Ye Guojin looked at Ye Linlang and begged, "Then please come and work overtime?"

This time the case is too big, and it involves things that are tested, and there are not a few.

The other inspectors were also busy and their feet did not touch the ground.

Even if Ye Guojin specially approved and said that the processing should be expedited, but the inspection here is not urgent?

"Okay, I'll call Mio Mio to get ready. ”

Ye Linlang borrowed the phone and informed Gong Mio to prepare in the laboratory.

Ye Linlang's laboratory is one of the best.

With the machines of an ordinary laboratory, it may take three days to produce DNA results, but Ye Linlang's laboratory can shorten the time by 60 percent.

"Then I'll notify the staff here to connect with you. ”

Ye Linlang responded: "Okay." ”

It was getting late.

Ye Linlang returned to the research institute in a car with various samples.

In the laboratory, Mio Gong greeted him and asked, "What is the case?"

"A huge case. ”

Ye Linlang took the background of the case to Gong Mio, he took the document and read it at a glance.

Then he asked in shock: "This ......?"

"Dude, don't ask, let's get to work!"
