"What day is it today? There are so many guests at home. Hey, Tong Wei, who are these two little girls?" Since his retirement, Chen Shishi's house has not been so lively for a long time. He was very happy and looked at Gao Xiaoqin and his sisters. asked.

"The children adopted by relatives at home are now studying at my place. I will take them to see them when I go to the capital this time. When I come back, I will come to your place for a meal. You won't welcome it, right?" Shen Long looked at it. There sat a middle-aged man in his forties and a young man in his thirties next to him.

Looking at the postures of the two people, one should be the leader and the other is the secretary. The leader looked familiar, as if he had seen it somewhere, but Shen Long couldn't remember it for a while.

"Hello, Grandpa Chen." Sister Gao Xiaoqin received Shen Long's instructions in advance and bowed to Chen Yanshi as soon as they entered the door.

"Welcome, of course you are welcome! What two handsome girls you are." Gao Xiaoqin's sisters were really lovable. Chen Shishi liked them as soon as he saw them. He quickly asked Wang Fuzhen to find something to eat for them, "Old lady, wash some more fruits for them." The two children eat, what do you like to eat? Oranges or apples?"

"No need to be polite to Grandpa Chen, you two go help grandma wash it!" Shen Long asked Gao Xiaoqin to help Wang Fuzhen, and handed the gifts to Chen Shishi and Chen Hai, "The monkey asked me to bring it to you, and some of me Souvenirs bought in the capital.”

Chen Yanshi was very happy with this unobtrusive attitude. He accepted the gift after seeing that it was not a very valuable thing, "Hey, you two just remember me. What else do you need to bring? It's so far away; I still have some at home." I won’t let me drink a few bottles of wine now, so you can take it with you when you leave!”

"Come, let me introduce to you. This is the nephew of one of my comrades in arms, Sha Ruijin, who serves as a senior municipal official in XX City. Xiao Jinzi, this is Chen Hai's classmate at Handong University. Qi Tongwei, who works at the Luzhou City Public Security Bureau Deputy Director." He handed the things to Chen Hai, and Chen Shiyan introduced them to each other.

"Hello, Secretary Sha." Shen Long stepped forward and stretched out his hands to shake Sha Ruijin's. No wonder he felt 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 chat slowly. I just listened to Mr. Chen talk about you for a long time." Sha Ruijin said with a smile. His attitude and expression were similar to those of Li Dakang, Zhao Lichun, Gao Yuliang, and Liang Qunfeng. The person also has a style, amiable but with a touch of majesty, which makes people feel both friendly and respected.

He became a senior listed official at such a young age. He was a big step ahead of Li Dakang and Gao Yuliang. No wonder he would parachute to Handong to replace Zhao Lichun as the top leader in the future. Shen Long sat down and said, "What did Mr. Chen say about me?"

"You are said to be capable. You have made great achievements many times. You have the courage to take risks in order to catch drug dealers. You have a high cultural level and are ahead of your peers in the application of various high technologies." Sha Ruijin leaned forward slightly. This action is very easy to make people feel. To create a favorable impression, especially when someone with a higher position talks to a lower-level person, he does not seem so condescending. It seems that Sha Ruijin has special training in manners and conversation. Of course, it may also be the experience accumulated from long-term work in the system.

"Thank you, Mr. Chen. These things are all our due duties." Shen Long couldn't help but think of the first meeting between Sha Ruijin and Qi Tongwei in the TV series. At that time, Qi Tongwei was helping Chen Yanshi hoe the ground, and was caught by Chen Yanshi. He made some sarcasm in front of Sha Ruijin, which left a very bad impression on Sha Ruijin.

Now the situation is reversed. Sha Ruijin has a good impression of him. If there are no big changes in the future and Sha Ruijin will still come to Handong Province, Shen Long's life will be much better.

"If everyone could do their part, the world would be a much better place!" Sha Ruijin laughed, "Come on, tell me about your DNA laboratory. From what Mr. Chen said, it seems Very powerful ah."

Sha Ruijin is the top leader in the city, and he must be more concerned about the city's public security situation, especially in recent years. Due to the reform of state-owned enterprises, the number of idle people in society has gradually increased, and the public security situation has also deteriorated. I just listened to what Chen Hai and Chen Shiyan said. Sha Ruijin had paid attention to this matter. Now that he saw the real owner, he naturally wanted to ask about it.

"DNA refers to deoxyribonucleic acid. Genes are composed of DNA. Everyone's DNA is different...different from fingerprints, DNA exists in more categories, such as hair follicles, blood, and saliva with epithelial cells. Wait, many criminals may not leave fingerprints at the scene, but it is difficult to control not to leave these things..." Shen Long briefly introduced Sha Ruijin's background knowledge.

"The introduction of DNA testing technology means that a large number of clues that could not be discovered before can be found, thereby reducing the difficulty of solving crimes and catching the criminal earlier and more accurately..."

"Well, the chief designer said it well. Science and technology are the primary productive forces. With this technology, it becomes relatively easy to solve crimes!" Sha Ruijin nodded, seeming to understand.

"How much will it cost to build this DNA laboratory? What kind of professionals are needed?" He asked very carefully, as if he was planning to equip the public security bureau within his jurisdiction with one.

"I spent nearly 20 million at that time, and it was possible thanks to the support of the city secretary Gao Yuliang. The professional and technical personnel were supported by the ministry; but during this time, the Department of Biology of Handong University cooperated with us, and to a certain extent The cost of these equipment has been reduced, and if we build it again now, it shouldn’t cost so much money," Shen Long said.

"As for people, these technologies are not difficult. Students in the biology department of general universities can master them after a period of training. If you are interested, you can send people to Luzhou. It just so happens that we are also working on it during this time. Colleagues from other places conduct training." This technology has gradually been promoted in the industry, and people often come to Luzhou to learn from it.

If we can use this opportunity to build a good relationship with Sha Ruijin, although it may not seem to be of much use now, it will be different in the future.

"Then I'll trouble you!" Sha Ruijin called to his secretary, "Xiao Liu, you can go to Luzhou later and get some information from Xiao Qi. I'll let our comrades from the municipal public security department study it."

"It's not so troublesome. I used to send information to colleagues in other places. The complete set of information is stored in the mailbox. You can leave an email address, or I can find a place to print it out for you now," Shen Long said.
