"What day is it? There are so many guests at home, yo, Tongwei, who are these two little girls? Since retiring, Chen Yanyan's family has not been so lively for a long time, he was very happy, looked at Sister Gao Xiaoqin and asked.

"The children adopted by relatives at home are now studying with me, and I will take them to the capital this time, and I will come to you by the way to eat, will you not welcome it?" Shen Long saw a middle-aged man of about forty sitting in the room, and a young man of about thirty next to him.

Looking at the posture of the two of them, one should be the leader and the other is the secretary, this leader still looks a little familiar, as if he has seen it somewhere, but Shen Long can't remember it for a while.

"Hello Grandpa Chen." Sister Gao Xiaoqin got Shen Long's orders in advance, and as soon as she entered the door, she bowed to Chen Yanyan.

"Welcome, of course welcome! What a handsome girl. The Gao Xiaoqin sisters are really likable, Chen Yanyan liked it when she saw it, and hurriedly beckoned Wang Fuzhen to find food for the two of them, "Old woman, wash some fruit for the two children to eat, what do you like to eat?" Orange or apple? ”

"Don't be polite to Grandpa Chen, you two go and help grandma wash!" Shen Long asked Sister Gao Xiaoqin to help Wang Fuzhen, and handed the gift to Chen Yanyan and Chen Hai by the way, "The monkey asked me to bring you, as well as some souvenirs I bought in the capital." ”

This invisible posture made Chen Yanyan very happy, and he accepted it when he saw that the gift was not too valuable, "Hey, you two can remember me, what else do you bring, this is far away; There are still a few bottles of wine at home, and the old woman won't let me drink them now, so you can take them with you when you leave! ”

"Come, let me introduce to you, this is the nephew of my comrade-in-arms, Sha Ruijin, who serves as a senior city official in XX City, Xiao Jinzi, this is Chen Hai's classmate at Handong University, Qi Tongwei, who is the deputy director of the Luzhou City Public Security Bureau." handed over the things to Chen Hai, and Chen Yanyan introduced them to each other.

"Hello Secretary Sha." Shen Long stepped forward and stretched out his hands to shake Sha Ruijin, no wonder it looked familiar, it turned out to be him, well, he is much younger than in the TV series now, no wonder he didn't get the right number for a while.

"Hello Comrade Xiao Qi, come, sit down and talk slowly, I heard Chen Lao talk about you for a long time just now." Sha Ruijin said with a smile, his attitude and expression are the same as those of Li Dakang, Zhao Lichun, Gao Yuliang, and Liang Qunfeng, and he is amiable with a touch of majesty, which makes people feel both cordial and respectful.

became a listed senior official at such a young age, a big step ahead of Li Dakang and Gao Yuliang, no wonder he could be parachuted into Handong to replace Zhao Lichun as the leader in the future, Shen Long sat down and said, "What did Chen Lao say about me?" ”

"Saying that you can do it, you have made great contributions many times, you dare to take risks in order to catch drug dealers, you have a high level of education, and you are ahead of your peers in the application of various high-tech." Sha Ruijin leaned forward slightly, this action is easy to make people feel good, especially when talking to people with relatively high positions and low-level objects, it seems that Sha Ruijin has specialized in behavior and conversation, of course, it may also be the experience accumulated in long-term work in the system.

"Elder Chen has won the award, these things are all due diligence." Shen Long couldn't help but think of the first meeting between Sha Ruijin and Qi Tongwei in the TV series, when Qi Tongwei was helping Chen Yanyan hoe the ground, and Chen Yanyan was sarcastic in front of Sha Ruijin, which left a very bad impression on Sha Ruijin.

Now it is just reversed, Sha Ruijin has a good impression of him, if there is no big change in the future, Sha Ruijin will still come to Handong Province, Shen Long's life will be much better.

"If everyone can do their part, the world will be a better place!" Sha Ruijin laughed, "Come, tell me about your DNA laboratory, it seems to be very powerful to hear Chen Lao." ”

Sha Ruijin is the number one in the city, and he must be more concerned about the city's public security situation, especially in the past few years, because of the reform of state-owned enterprises, the number of idle people in society has gradually increased, and the public security situation has also deteriorated.

"DNA refers to deoxyribonucleic acid, genes are made up of DNA, and everyone's DNA is different...... Unlike fingerprints, DNA exists in more categories, hair follicles, blood, saliva with epithelial cells, etc., many criminals may not leave fingerprints at the scene, but it is difficult to control not leaving these things....... "Shen Long briefly introduced the background knowledge to Sha Ruijin.

"The introduction of DNA testing technology means that a large number of previously undiscovered clues can be found, thereby reducing the difficulty of solving the case and catching the murderer earlier and more accurately....."

"Well, the chief designer said well, science and technology are the primary productive forces, and with this technology, it will be relatively easy to solve the case!" Sha Ruijin nodded, as if he understood.

"How much does it cost to build this DNA lab? What kind of professionals are needed? He asked very carefully, as if he was planning to add one to the public security bureau in his jurisdiction.

"I spent nearly 20 million at that time, thanks to the support of Secretary Gao Yuliang in the city, and the professional and technical personnel were supported by the ministry; However, during this time, the Department of Biology of Handong University cooperated with us, which reduced the cost of these equipment to a certain extent, and if we build it now, it should not need so much money. Shen Long introduced.

"As for people, these techniques are not very difficult, the average university biology students can get started after a period of training, if you are interested, you can send people to Luzhou, it just so happens that we are also training colleagues in other places during this time." This technology has gradually spread in the industry, and people often come to Luzhou to learn from experience.

If you can use this opportunity to have a good relationship with Sha Ruijin, although it may not be of much use at the moment, it will be different in the future.

"Then I'm sorry for you!" Sha Ruijin beckoned to his secretary, "Xiao Liu, go back to Luzhou, get some materials from Xiao Qi and come back, and I will let the comrades of our city's public security department study and study." ”

"I don't have to be so troublesome, I used to send information to colleagues in the field, and the full set of information is stored in the mailbox, you can leave an email, or I will find a place to print it out for you now." Shen Long said.

"Hey, it's all computerized office! Comrade Xiao Qi, you have always been at the forefront of the times. Sha Ruijin smiled again, "Fortunately, I didn't lag too far behind, Xiao Liu, leave your mailbox to Xiao Qi." ”
