, and now he is marrying Gu Xinli? 　　Grandpa Jiang listened to their conversation and was silent for a while before saying, "Xiaoxi, I actually have a guess. Something is very likely to have happened to that girl Gu Xinli." 　　Gu Xiaoxi immediately looked at her grandfather, "You mean, it was done by Old Man Gu and Old Lady Gu?" 　　Grandpa Jiang sighed, "These days, you can't go anywhere without a letter of introduction. She disappeared within two days of getting the two thousand yuan. At that time, her family thought she left quietly. But when Ning Hai came later, I met him once. From his tone, Ning Hai had agreed with Gu Xinli to go back after getting the money. So he also knew that Gu Xinli was going to blackmail the Lu family." 　　At this point, he paused before saying, "I also know something about the Lu family. They are not easy to deal with. Logically, they would not give Gu Xinli so much money so readily. Because even if the fact that old Lu and Old Lady Gu had an illegitimate child was exposed, it would not have much impact. So, Gu Xinli should have known some other secrets..." 　　 　　Gu Xiaoxi carefully recalled Gu Xinli's state at the time, and finally nodded. 　　"It's possible. She told me at the time that she had been watching old man Gu for several years and knew a lot." 　　"Leave the Gu family's affairs to me. Since we are back this time and have time, let's investigate the affairs of the Gu and Xie families." Lu Jiansen suddenly spoke. 　　There were many reasons why this matter was not handled well before. First, there were time and geographical restrictions, and it was difficult to obtain evidence. 　　Second, he had reported it to his superiors and talked to his father. The matter involved the Xie family. Because of the particularity of the current environment, it does take time, effort, and effort to move some people. 　　Otherwise, if you are not careful, you will be bitten back, and the reasonable and righteous party will become the one who is sent down to suffer. 　　However, before this transfer, Commander Tang told him something. The country will soon make big moves, and some national parasites will be dealt with soon. 　　Gu Xiaoxi hesitated for a moment and said, "Didn't we just buy a blood tester this time? Let's find a way to get everyone in the Xie family to take a test." 　　Upon hearing this, Yu Chengshuang immediately said, "Leave this to me, Lu Jiansen! I have a month to investigate this for you." 　　Lu Jiansen nodded without saying much. 　　He planned to talk to Yu Chengshuang later. 　　However, before that, he planned to go to the Public Security Bureau to find out more about the situation. 　　Gu Xiaoxi thought about it and simply left the child to the care of his grandfather and his aunt, and went to the Huaicheng Public Security Bureau with Lu Jiansen and Yu Chengshuang. 　　Because of Lu Jiansen's identity, the people in the Public Security Bureau were very cooperative. As soon as they asked, the police officers in charge of the case told them all the investigation details. 　　"After Gu Xinli's disappearance was reported, we investigated the Gu family. They had indeed unanimously believed that Gu Xinli left Huaicheng after getting the money, so Gu Weiguo kept scolding her for being unfilial and not giving them money to spend..." 　　"We also investigated the Lu family, but the Lu family said that they had never seen Gu Xinli again after extorting money from their family. After that, they went to work and school, and their schedules were normal. Moreover, when Gu Xinli disappeared, they all had an alibi..." 　　After hearing this, Lu Jiansen asked, "Did the Lu family explain why Gu Xinli blackmailed them?" 　　Captain Li, who was in charge of the case, said in a difficult way, "They said that the Lu family took the initiative to explain that Xiaomei Gu was born to the old lady of the Gu family and old man Lu. Lu Yishen, the director of the Lu family in the street office, asked us to protect his privacy. Only a few of us who are in charge of this case know about this..." 　　Gu Xiaoxi frowned slightly, always feeling that it was a bit unreasonable. 　　"The Lu family gave the money so readily? Don't they have any complaints?" 　　Captain Li nodded, "Of course they have complaints, but Lu Yisheng wants to save face, so he just gave the money and bought a peace of mind." 　　Gu Xiaoxi chuckled, "Then this peace of mind is quite expensive." 　　A young policeman next to him whispered, "It's expensive, of course. Even if the Lu family has an alibi that proves they haven't seen Gu Xinli after giving the money, I still suspect that Gu Xinli's disappearance has something to do with them." 　　Lu Jiansen glanced at the young policeman who was speaking, "Do you know something else?" The 　　young policeman glanced at his captain and continued, "Old man Lu has a tough personality and is usually very stingy. Compared to two thousand yuan, losing a little face is nothing. We also can't arrest people directly without evidence, and our suspicion has always been there. We've been keeping an eye on the Lu family for several days, but we didn't find anything." 　　As they were talking, a policeman knocked on the door and came in to report, "Captain Li, that Ning Hai is here again." 　　"Let him in, I just happen to have something to ask him." Lu Jiansen spoke immediately. 　　Captain Li nodded and had Ning Hai brought to the interview room. 　　Ning Hai knew Gu Xiaoxi and Lu Jiansen, but he was still very surprised to see them at the Huaicheng Public Security Bureau. 　　"You...how come you are here?" Ning Hai stuttered a little, and his expression was a little flustered. 　　Gu Xiaoxi squinted his eyes slightly, "We are here, why are you panicking?" 　　Ning Hai stood up straight at once, and his voice became tense, "Who is panicking?" 　　Gu Xiaoxi glanced at Lu Jiansen, motioning him not to speak, and then looked at him with eyes that saw through everything. 　　"Of course we came here because we have important information. We were originally planning to let the police call you in for questioning, but it just so happens that you came here on your own, so just take the initiative to confess!" 　　At this point, she paused and gave another warning. 　　"Leniency to those who confess, severity to those who resist, tell the truth, otherwise your whole life..." 　　She didn't say the rest, but Ning Hai's face suddenly turned pale. 　　A stern look flashed in Lu Jiansen's eyes. He must have really committed a serious crime! 　　Yu Chengshuang was also a little surprised. He didn't expect that Xiaoxi's two sentences seemed to have revealed something extraordinary. 　　The two police officers next to him were stunned for a moment and looked at each other. 　　 　　Chapter 508 Are all the tests completed? 　　Ning Hai opened his mouth at first, but quickly closed it again. 　　He couldn't say it, he must not say it. 　　If he said it, his whole life might be ruined. ■This work was organized and uploaded by Situ online readers. 　　Gu Xiaoxi looked at his expression, sneered, and spoke again: "Today is the last chance. With the disappearance of Gu Xinli, our investigation of you is also very comprehensive. If what you said is different from what Gu Xinli said, you should know what the result will be." After she finished speaking 　　, she looked into Ning Hai's eyes with a sense of oppression . 　　Ning Hai couldn't hold it in anymore when he heard this, and said excitedly: "No, no, you must not believe what Gu Xinli said. Yin Chunsheng's death has nothing to do with me, it really has nothing to do with me..." 　　Gu Xiaoxi's heart skipped a beat, and she turned to look at Lu Jiansen. 　　Lu Jiansen was shocked, but his face was calm and serious. "Whether it has anything to do with you or not is not something you can say with just your mouth." 　　Ning Hai was anxious when he heard it, and hurriedly said, "It really has nothing to do with me. I tell you, Yin Chunsheng fell into the river that day by accident, it was really an accident. We didn't expect him to jump into the river to save people, and finally drowned because of exhaustion. This is really an accident." 　　 　　Lu Jiansen's eyebrows trembled, "You didn't expect him to jump into the river to save people, so what was in your calculation?" 　　The two police officers didn't dare to breathe when they heard this. 　　Because when dealing with the case of Gu Xinli's disappearance, they knew Yin Chunsheng's identity very well. He was also a regimental-level cadre in the army! 　　Could it be that the death of this military cadre was also strange? 　　This is terrifying to think about! 　　Ning Hai was really afraid that Gu Xinli would dump the pot on him, and he was also afraid of being accused of killing soldiers, so he quickly explained. 　　"Gu Xinli put drugs in the soup that Yin Chunsheng drank that day. She originally just wanted to knock Yin Chunsheng unconscious and take away the very valuable jade pendant. Later, Yin Chunsheng had something to do after drinking the soup and left... We didn't expect it to be such a coincidence that he saved someone in the water and drowned when the drug took effect..." 　　Ning Hai's tears and snot fell when he said this, 　　and he was very regretful. "Although I am a little selfish, I really dare not kill anyone. This is really an accident, you must believe me..." 　　After Ning Hai finished speaking, he raised his head and said to Gu Xiaoxi: "If you really want to blame, blame Gu Xinli who put the drugs in. It was her. This was all her idea. She has put drugs in the food you ate before, right? She has a criminal record. Really, believe me. It's all her fault, it's all her idea..." 　　Gu Xiaoxi fell silent. 　　This matter involves the death of Yin Chunsheng, and it is no longer a question of whether she believes it or not. 　　Lu Jiansen asked Ning Hai a few more questions, and then directly called the division commander Tang of the Qingbei Military Region using the phone of the Public Security Bureau. 　　After the call, Lu Jiansen said to Xiaoxi: "Someone will be in charge of this matter soon. Ning Hai will be detained first, and we will go back first." 　　"Okay." Gu Xiaoxi nodded. 　　It turned out that she met Ning Hai just to ask about Gu Xinli, but things turned out to be another direction. 　　After returning home, Lu Jiansen and Yu Chengshuang chatted in the room for a while, and then went out. 　　Gu Xiaoxi stayed at home with her grandfather to take care of the two babies. 　　Of course, most of the time, it was her grandfather and aunt who took care of the children, and she was studying the mechanical arms next to them. 　　She has been working in the hospital for a long time and has seen too many people with disabled hands and feet, including many soldiers. 　　If they can be equipped with prosthetic limbs, it will be a major event that can change a person's life. 　　After figuring out the structure and usage of the mechanical arm, she returned to her room and used the shuttle card to go to the Nine Star Alliance Military Hospital. With the authority of a special doctor in the universe, she personally watched the installation surgery of the mechanical arm. 　　In the interstellar, the requirements for selecting a mechanical arm are very strict. They can repair ordinary broken limbs with some gene repair fluid. 　　If the gene is broken, it is impossible to use gene culture fluid to re-cultivate new limbs that match oneself, so mechanical arms and legs will be installed. 　　Of course, such treatment methods are also very expensive, and not everyone in the interstellar can afford it. 　　Because the mechanical arm of the Nine Star Alliance Military Hospital has been updated for 366 generations, the most advanced mechanical arm is now more dexterous than the original human hand, and it is also multifunctional. 　　Gu Xiaoxi originally planned to return to Huaicheng after watching the operation, but after Dean Si Lan knew that she was in the hospital, he directly gave her a new task. 　　"Doctor Gu, I just received an urgent task here, which is to analyze the blood of an unknown nine-star alien beast. Do you have time to try to deal with it?" 　　Gu Xiaoxi nodded, "Sure." 　　She is very good at analyzing and separating blood, and it doesn't take too much time. 　　Seeing that she agreed, Dean Si Lan took Gu Xiaoxi to the blood test center of the hospital and entered a high-tech laboratory. 　　There were all kinds of equipment inside, and there were a lot of people. 　　At this time, at least ten people were holding a tube of green in Sichuan pink in their hands, studying the blood of the alien beast inside. 　　After Gu Xiaoxi went over, she was also assigned a tube of blood and a quiet testing platform. 　　Because everyone was busy now, Dean Si Lan did not introduce it to her. 　　Gu Xiaoxi took the initiative to do disinfection and sterilization tests next to her, washed her hands, put on protective gloves, and then started her work. 　　She didn't need too many complicated testing equipment. Once the secondary fine separation technique and the perfect separation technique were used, the blood that looked a little messy and mottled was separated. 　　A tube of pink-green blood was directly separated into 22 kinds of liquids, which were placed in different tubes and labeled. 　　After finishing, she first made a backup, and then took a small portion and put it into the blood test center's testing instrument for detailed data analysis. 　　Ten minutes later, she got two sheets of paper with detailed test results. 　　She looked at the
