Solving the case: Combining the police dog's olfactory genes at the beginning

The special task force immediately excavated the three areas and discovered three more skeletons. Preliminary assessments suggest these skeletons likely belong to the missing Xu Ziming, Zhou Yihang, and Zhao Tianyu.

"Seal off the scene immediately!" Luo Fei ordered. "Keep all findings confidential for now and await the DNA comparison results."

A day later, DNA comparison confirmed the identities of the four skeletons: they were the missing Xue Yuankai, Xu Ziming, Zhou Yihang, and Zhao Tianyu.

The truth of the case gradually became clear: Li Wenxuan's parents likely kidnapped and murdered these rich kids to avenge their son.

At the meeting, Luo Fei analyzed: "Based on the existing clues, Li Wenxuan's parents and their third child, Li Wenhao, are likely the masterminds behind the revenge. Li Wenhao is Li Wenxuan's younger brother, who was adopted by his uncle and later returned to his parents. The three of them may have left Jiangcheng together, changed their names, and started planning their revenge."

The special task force began a full-scale investigation into Li Wenhao's whereabouts, but discovered that he may have completely changed his identity and was difficult to track down.

Although the case has not been fully solved, Luo Fei decided to announce the discovery of four sets of remains, but temporarily concealed its connection to the Li Wenxuan case.

After the news was released, the victim's family reacted strongly, especially Xiao Yuanfeng, who finally realized that his son might have been murdered and began to put pressure on Luo Fei through various channels, demanding that the case be solved as soon as possible.

Even Lei Wanting personally intervened in the case: "Luo Fei, this is the first major case since the establishment of the special case team. It must be solved as soon as possible. There is a lot of pressure from all sides. Just tell me how many resources you need."

Luo Fei felt unprecedented pressure. This not only concerned the wrongful deaths of four people, but also the reputation of the special task force, and even more so, whether judicial justice could be upheld.

Despite pressure from all sides, Luo Fei remained unusually calm. At the morning meeting the following day, he made an unexpected decision: "This weekend, the entire special task force will have a day off. Tomorrow I'll treat everyone to a barbecue at my villa."

This decision stunned all the team members. Zhou Xiaobei was the first to react: "Captain Luo, the case is so tense, can we really relax?"

Wang Feifei said with a smile, "I love Captain Luo's unconventional style."

Yuan Bingyan looked at Luo Fei with admiration: "It's really not easy to stay calm under such great pressure."

Su Muchen also rarely expressed his agreement: "I am impressed by Captain Luo's drawing skills, and this decision shows his leadership qualities even more."

Even Chen Yifan, Luo's love rival, had to admit: "Although I am unwilling, Captain Luo is indeed capable."

Wu Peixiong was full of admiration for Luo Fei: "I will never forget the feat of Captain Luo carrying the safe on his shoulder!"

The next day, Luo Fei borrowed a bus and driver Lao Wang from the Xiahegou Police Station to take the special case team members to Jinfo Mountain, dozens of kilometers away from Jiangcheng. Chen Xuanran originally wanted to go as well, but was unable to do so due to a last-minute work arrangement.

Yuan Bingyan was secretly pleased to learn that Chen Xuanran wasn't going. Chen Yifan, on the other hand, was somewhat disappointed; he had hoped to use this opportunity to get closer to Yuan Bingyan.

Everyone had a great time at Jinfo Mountain and didn't set off back to Jiangcheng until 6 p.m.

Upon returning to Jiangcheng, Luo Fei asked driver Lao Wang to take everyone back to the villa first, while he got out of the car near the farmers' market. He remembered that Chen Xuanran had mentioned buying barbecue ingredients there.

In the bustling market, Luo Fei quickly found Chen Xuanran carrying large bags and small packages. He walked up to her and naturally took the plastic bags from her hands: "Why didn't you have the nanny buy them?"

Chen Xuanran wiped the sweat from his forehead: "Grandma is playing mahjong, and I don't want to disturb her. Besides, ingredients that I personally select are the freshest."

Luo Fei praised, "You're so sensible."

Chen Xuanran joked, "Yeah, some people take their pretty female colleagues out to play, but leave me, their real girlfriend, to prepare the barbecue."

Just as Luo Fei was about to explain, he suddenly noticed a middle-aged woman standing at the entrance of the dried goods store who looked familiar. Upon closer inspection, he recognized her as Xiao Dingkun's nanny.

This discovery immediately put him on alert. He remembered that Xiao Dingkun had also disappeared on his birthday, and the killer knew Xiao Dingkun's whereabouts perfectly. And the person who knew Xiao Dingkun's daily routine best was his family's nanny.

Luo Fei activated his super hearing and clearly heard the conversation between the nanny and another woman.

“The atmosphere at the Xiao family is very tense right now,” the nanny said in a low voice. “Ever since the young master went missing, the master and mistress have hardly eaten anything and have been locked in their room all day.”

Another woman asked, "So your job is much easier now?"

"What's so relaxing? I'm even more on edge now," the nanny sighed. "I'm terrified of saying something wrong and upsetting them."

Luo Fei deactivated his super hearing and stepped forward: "Hello, are you Mr. Xiao Dingkun's nanny?"

The nanny turned her head in surprise: "Yes, who are you?"

"I am Luo Fei from the National Security Bureau." He showed his identification. "And who was the person you were just speaking to?"

The nanny explained, "That was my former colleague. She doesn't do housekeeping anymore. We just happened to run into each other today and chatted for a bit."

Luo Fei pressed further, "Shouldn't you be staying at the Xiao family's? What are you doing here?"

The nanny replied, "I took the day off to go home. I live in the South Bay area, not far from here."

This information stirred something within Luo Fei. He thanked the nanny and quickly left with Chen Xuanran.

"What's wrong?" Chen Xuanran asked, puzzled.

Luo Fei's expression was serious: "I may have found an important clue. Xiao Dingkun's nanny lives in the South Bay District, and Li Wenxuan's family also lives in the South Bay District. This is probably not a coincidence."

He immediately called Zhou Xiaobei: "Xiaobei, immediately check the detailed information of Xiao Dingkun's nanny, especially her connection with the South Bay District. This may be a breakthrough."

Looking at Luo Fei's focused profile, Chen Xuanran couldn't help but laugh: "Looks like someone's barbecue feast is going to be canceled."

Luo Fei put away his phone and took the ingredients from Chen Xuanran: "No, the barbecue will proceed as planned. The more crucial the moment, the more we need to stay calm. Let's go, everyone's waiting for us."

The two carried large and small bags of groceries towards the parking lot.

That evening, Luo Fei hosted a barbecue in his backyard. Chen Xuanran, as the hostess, busied herself preparing ingredients and seasonings for everyone, barely having time to eat herself.

The special task force members were full of praise for Chen Xuanran's competence. Zhou Xiaobei ate while exclaiming, "Officer Chen's cooking skills are really good. This roast meat is crispy on the outside and tender on the inside, and the taste is just right."

Wang Feifei chimed in, "Yes, I didn't expect Officer Chen to be such a good cook."

Even Chen Yifan had a better impression of Chen Xuanran. While eating his kebabs, he couldn't help but fantasize about how happy he would be if Chen Xuanran were his girlfriend. Yuan Bingyan didn't say anything, but she was a little unconvinced and secretly thought that she could do just as well if she were in Chen Xuanran's shoes.

The barbecue feast was lively, and everyone enjoyed the delicious food, washing away the fatigue of the past few days. Yuan Bingyan drank quite a bit of red wine, and her face flushed.

After the banquet, everyone prepared to take a taxi home. Chen Yifan took the opportunity to walk up to Chen Xuanran and politely asked, "Officer Chen, where do you live? If it's on your way, I can give you a ride home."

Chen Xuanran replied naturally, "I live here. I've been living with Luo Fei for several months now."

These words struck Chen Yifan like a bolt from the blue, leaving him stunned and pale. He had no idea that Chen Xuanran was already living with Luo Fei.

Yuan Bingyan noticed that Chen Yifan was not in a good mood, so she quickly stepped forward and pulled him away: "Yifan, let's take a taxi." After saying goodbye to Chen Xuanran and Luo Fei, she hurriedly pulled the distraught Chen Yifan away.

In the car, Chen Yifan remained silent, his eyes vacant. Yuan Bingyan gently comforted him, "Don't be too sad. You can't force matters of the heart."

The driver saw Chen Yifan's reaction in the rearview mirror and silently handed him a pack of tissues.

The next day, Chen Yifan came to the office and told Yuan Bingyan directly, "I want to resign and go back to Shanghai."

Yuan Bingyan was surprised and advised him, "Yifan, don't be impulsive. It's not worth giving up your job for a relationship."

But Chen Yifan was adamant: "I've made up my mind. There's nothing to miss here."

Left with no other choice, Yuan Bingyan had to tell Luo Fei about it.

Luo Fei was also surprised: "Yifan wants to resign? Why?"

Yuan Bingyan sighed: "Actually, he has always liked Chen Xuanran. He was devastated when he found out yesterday that you two were living together."

Luo Fei frowned: "I thought he liked you. Didn't he say before that he fell in love with you at first sight?"

Yuan Bingyan shook her head: "That's all in the past. Later, he met Chen Xuanran and fell in love with someone else. I didn't expect that Chen Xuanran is already your girlfriend."

Luo Fei pondered for a moment: "Since he has made this decision, perhaps leaving Jiangcheng is better for him. Seeing Xuanran every day here will only cause him more pain."

Just then, Luo Fei's phone rang. The caller ID showed it was the captain of the anti-drug squad.

"Captain Luo, we found some photos of your father while sorting through the files. We're going to have Zeng Mengxue send them to you," the other person said.

After informing the gatekeeper to let them through, Luo Fei said to Yuan Bingyan, "I have approved Yifan's resignation. You organize everyone to see him off."

When the special task force members learned that Chen Yifan was leaving, they were all very surprised and disappointed. They gathered together, trying to persuade him one last time, but seeing that Chen Yifan was determined to go, they had no choice but to give up.

Just as everyone was seeing Chen Yifan to the door, a police car pulled up and stopped. A policewoman got out of the car; it was Zeng Mengxue, who had come to deliver the photos.

The moment Chen Yifan saw Zeng Mengxue, he froze. He stared intently at her, his eyes flashing with that familiar light once again.

Seeing Chen Yifan's expression, Yuan Bingyan sighed helplessly, "Well, he's set his sights on something new again."

Sure enough, Chen Yifan suddenly turned to Luo Fei and said, "Captain Luo, I'm not leaving! I want to withdraw my resignation!"

The special case team members present were all shocked. Zhou Xiaobei couldn't help but say, "Yifan, aren't you being too frivolous? We tried to persuade you for so long, but it was no use. You changed your mind as soon as you saw the pretty policewoman?"

Chen Yifan explained earnestly, "It's not what you think. The Special Case Team is in dire need of manpower right now, and I can't leave at this time. I've decided to stay in Jiangcheng and serve the National Security Bureau and the people of Daxia!"

Although Luo Fei was puzzled, he still agreed: "Okay, welcome back. But you must remember, you can only have respect for Chen Xuanran, and you can't have any other thoughts about him."

Chen Yifan immediately apologized to Luo Fei and Chen Xuanran: "I'm sorry, I was too impulsive before. I promise that from now on I will only treat Officer Chen as a colleague and senior to be respected."

Luo Fei nodded: "Now that you're back, get to work. Go check the information of the nannies of the four deceased and see if there's any connection."

Chen Yifan immediately took action and brought back the investigation results a day later: "The four nannies are named Li Kaiqiong, Tang Suyun, Luo Yanqiu, and Xie Yunfen. They belong to different domestic service companies, do not know each other, and the investigation shows that they have no connection with Li Wenxuan's family."

This result surprised Luo Fei, and he began to doubt whether his previous guesses were correct.

Suddenly, Luo Fei remembered the strange-looking woman he had encountered at the farmers' market. He closed his eyes, activated his super memory, picked up a paintbrush, and quickly sketched the woman's appearance on the paper.

"Yifan, go and investigate this person." Luo Fei handed the portrait to Chen Yifan. "I need her detailed information."

Chen Yifan took the portrait, and before leaving, he couldn't help but ask, "Captain Luo, who was that policewoman just now?"

Luo Fei understood his thoughts: "Zeng Mengxue is a new trainee officer in the narcotics squad. I can introduce you to her after the case is closed."

Chen Yifan immediately perked up: "Thank you, Captain Luo! I'll go check right away!" Encouraged by love, he threw himself into the mission with even greater enthusiasm.

Luo Fei watched Chen Yifan's departing figure and shook his head helplessly. This fickle colleague, while a headache, was undeniably capable at work. He now only hoped that Chen Yifan was serious this time and wouldn't fall in love with every woman he met again like before.

Chen Yifan was very efficient and quickly brought back all the information about the woman: "Qiu Sufeng, 52 years old, a local of Jiangcheng, works in domestic service. Her husband, Liao Mingkang, is the owner of a roast meat shop. You should know her son, Liao Anqian—he used to work with Xiao Dingkun at Dayang Police Station and was later transferred to Xiaohegou as the head of the police station."

Luo Fei immediately realized the connection: "Qiu Sufeng has connections with the companies that employ the nannies of the four deceased? That's too much of a coincidence. Check all of Liao Anqian's information."

Zhou Xiaobei quickly retrieved Liao Anqian's information and photos, but found that there was no criminal information displayed above Liao Anqian and his wife's heads.

"That's strange. If they were involved, there should be relevant information," Zhou Xiaobei said, puzzled.

Just then, the forensic department of the Jiangcheng Criminal Investigation Team made a new discovery.

Sister Zou called, her tone grave: "Captain Luo, we found unusual knife marks on the bones of the four victims. These marks were left when someone used a knife to remove muscle before they died, similar to the scratches on pork bones in the market."

Yuan Bingyan exclaimed, "This is death by a thousand cuts!"

Luo Fei's expression was grim: "This shows that the murderer harbored immense hatred for the perpetrators who killed Li Wenxuan. Li Wenxuan's parents are now even more suspicious." (End of Chapter)
