In fact, before Yuan Hui'e committed suicide, there was another small episode between the morning and the morning of the same day, which also led to a shift in the protection focus of Beiting to a certain extent, thus losing the effective monitoring of Yuan Hui'e on that day. It turned out that after Liu Xu'er got up in the morning, she found that her toothache was very bad, and she couldn't bear it, so she left the study to find Yuan Hui'e, but she unexpectedly found that her mother was not at home. Because the time at that time was very close to the time when her mother usually went out to buy vegetables, Liu Xu'er thought that Yuan Hui'e was going to buy vegetables, but she did not realize the fact that her mother ran away from home.

Subsequently, Liu Xu'er made three consecutive calls to Yuan Hui'e's mobile phone, but each time she couldn't get through, and she felt a little strange at this time. Because if the mother was shopping for groceries and didn't hear it, she should at least be able to get through, but there was a busy tone on the other end of the phone, but this trace of doubt was immediately replaced by the pain of the teeth. Liu Xu'er was in unbearable pain, she didn't want to wait for her mother to come home, so she had no choice but to call her tutor Zheng Xing for help, and ask Zheng Xing to take her to a nearby dental clinic for help.

Liu Xue'er was going to one of the best private dental clinics in Hong Kong City, where she had frequent tooth pain and tooth decay when she was a child, and Yuan Hui'e brought her here. The reputation here is particularly good, the doctor's skills are excellent, and the fees are high, according to Yuan Hui'e's usual style, everything must be brought to her daughter for the best, and it is not surprising that the treatment is not surprising. But Liu Xu'er doesn't like it very much, because of its good reputation, so there are many patients, and it is easy to mess up when there are more people, but she doesn't know other places, so she can only run to this familiar place if she has a toothache.

The clinic has been open for many years, and the equipment has become a little outdated, although there are many new equipment, but after all, it is impossible to compare with the new ones. In order to allow the doctor to see the patient's mouth clearly, the lights in the room are particularly dazzling and very dazzling, the sound of the squirting drill is very harsh, and in the room, there are sharp tweezers for tooth extraction, scalpels for cutting gums, and rickety treatment instruments, all piled up in every consultation room. And because of the large number of patients, the long queues, doctors and nurses are busy, they often accept patients one by one, and then treat them, there is no respite at all, sometimes they have to work more than ten hours a day. Some doctors stared at the lights for a long time, and their eyes felt dizzy and sleepy.

Liu Wu'er was placed on a medical instrument near the inside, and a nurse sister first gave her some examinations, because Liu Wu'er had also been here before, because the teeth did not grow in the inherent direction, but grew crookedly, resulting in touching another normal tooth, the two teeth collided under the gums, and gradually the flesh was also drilled, so it hurt. That day, because Liu Wu'er was busy going to piano lessons, she didn't deal with it, but just prescribed some anti-inflammatory drugs. Therefore, the doctor at the clinic thought that she might still have the same problem, so he asked the nurse to clean her mouth first, and then prepare for a minor operation to extract the misaligned tooth. At her age, she can grow new teeth on her own, so that's not a problem.

The nurse first poured a glass of plain water and rinsed her mouth, then used a cotton swab to stick alcohol and smeared it along her gums to disinfect it. But she may have been working too long today, and her hand shook accidentally, and the cotton swab deviated from the position of her teeth and applied it to her tongue. At the same time, Liu Yu'er's tongue subconsciously contracted naturally, and directly attached the cotton swab to his tongue and brought it to his throat, horizontal inside.

Liu Wu'er felt very uncomfortable and wanted to reach out and grab it, but was stopped by the nurse. She told her that she couldn't move because her hands were not clean and would ruin the disinfection effect, and then the nurse took out a pair of tweezers and gently removed the cotton swab from her mouth. Then the nurse continued to disinfect Liu Wu'er's mouth, and at the same time, she also saw that, as the doctor said, Liu Wu'er's crooked tooth before did not mean to correct it, and it still hit the good tooth next to it, and it was almost stuck together, which should be the root of Liu Wu'er's toothache.

Zheng Xing stood outside the clinic for a while, feeling a little embarrassed, the clinic was full of people, very busy, but he had nothing to do, and standing there was still a little in the way. He took out his mobile phone, swiped social software, watched the news for a while, felt that his eyes were a little sore, so he put away his mobile phone again and paced in the clinic.

After a long time, Liu Wu'er still didn't come out, he was really bored, so he entrusted Liu Wu'er to her dental doctor, and went out alone, and he also told the doctor to take care of Liu Wu'er, and once the operation was completed, he would notify himself to come back to pick her up. After Zheng Xing went out, he didn't have a clear purpose, he just wanted to come out and relax, these days he is basically curled up in a single apartment, and he is really stuffy, so he wants to take this opportunity to go around outside, which can be regarded as soothing and soothing his mood.

Zheng Xing didn't know that after he walked out of the dental clinic, there were two pairs of eyes that had been secretly staring at him and following him all the way, those two people were Wan Yongkun and Fat Sheng. Since taking over this task, Wan Yongkun has never taken his eyes off where Zheng Xing is, but he didn't find anything, and it was very easy to monitor, because Zheng Xing hardly went out except for the occasional visit to Liu's house, but avoided being followed on the road. It wasn't until today that he was seen taking Liu Xu'er to the dental clinic, Wan Yongkun reported the situation to Li Yiting in time after seeing Zheng Xing leave Liu Xu'er alone, Li Yiting asked him and Fat Sheng to focus on Zheng Xing, as for Liu Xu'er, there was no need for the two of them to worry about it.

The nurse at the dental clinic finally cleaned her mouth thoroughly, and after the relevant examinations and preparations, the doctor came to perform a minor tooth extraction operation. The doctor found that the little girl was not accompanied by her family, only a private doctor was on his side, and he thought it was a little strange, so he asked if he needed to wait for her mother to come and start again, after all, tooth extraction was very painful, and he was worried that the little girl would not be able to stand it. But Liu Xu'er felt sorry for her mother, knowing that Yuan Hui'e was in a bad mood, and she didn't inform her mother just after the conflict last night, she didn't know that her mother had run away from home at this time and would die soon.

The doctor had no choice but to do so, first gave Liu Wu'er an injection of anesthesia, because the needle needs to be directly hit on the gums, so it hurts very much, Liu Wu'er's two small hands are clenched into fists, her eyes are closed, but the pain still makes her silently shed tears. Fortunately, the anesthesia took effect quickly, and the local anesthesia in the mouth made Liu Wu'er no longer feel pain, and she relaxed a little, and the doctor was ready to start working. He first extracted the broken tooth, and then repaired the broken gum, and the doctor found that the good tooth next to him was not affected, so the problem was not serious, and only the bad tooth needed to be cleaned up. However, during the repair, the doctor found that there were still some tiny fragments of the tooth left inside, so he asked the nurse to bring him tweezers to retrieve them.

The nurse, who had made a lot of mistakes, didn't hear the doctor clearly, maybe it was too noisy, maybe it was the noise of the machine that made her a little confused, and she magically handed a sharp scalpel directly into the doctor's hand. Before the doctor could speak, the treatment instrument on Liu Wu'er's head suddenly fell apart for some reason, and the huge rocker arm fell down, and the dental drill on it completely lost control and smashed impartially on the back of the doctor's hand. The doctor was about to talk to the nurse about changing the tweezers, but he didn't notice all the suddenness, and immediately felt a sharp pain in the back of his hand, and he subconsciously raised his hand and turned the tip of the scalpel to the side. The swollen eyes of the light were about to turn their heads to avoid the light, and their heads just stayed in the area where the scalpel was wielded, and what was even more terrifying was that neither the doctor nor the willow catkins could see the position of the scalpel and the head, and they didn't know what would happen next.

Seeing that the scalpel was about to poke into Liu Wu'er's little head, her life was about to be lost, and at the last moment, a strong hand suddenly stepped forward, holding the scalpel in the doctor's hand tightly, preventing it from swinging forward, this person was wearing a white coat and a mask, as if another doctor was dressing;

These two people are none other than Xu Jingnan and Liu Zichen, in fact, the Beiting Detective Agency has always maintained a comprehensive monitoring of the Liu family. After Liu Xu'er was taken out of the house by Zheng Xing, it aroused their vigilance, because everyone was worried that Zheng Xing might attack Liu Xu'er, Liu Zichen, who was monitoring near Liu's house at the time, quickly followed, and immediately notified Li Yiting after finding that the two had walked into the dental clinic.

Because he was not familiar with the internal situation, Li Yiting arranged for Xu Jingnan and Liu Zichen to enter inside pretending to be doctors and nurses to continue monitoring. It just so happened that this clinic was really busy, and everyone couldn't take care of their own affairs, so they didn't have time to take care of anything else, and no one found out about these two fake doctors and nurses.

It was precisely because of the particularity of Zheng Xing's identity that Li Yiting was very worried that he would really harm Liu Xu'er, so he quickly led Kuang Suo and Xu Jingnan to the clinic, and after meeting with Liu Zichen, he made this plan to cooperate with the outside world. If there is something inside, Xu Jingnan and Liu Zichen can deal with it directly, while Li Yiting and Kuangsuo stayed outside to prepare to respond, as for Wan Yongkun and Pang Sheng, the two of them followed Zheng Xing to the clinic, so this time Beiting is very well-staffed here.

It was only later that Zheng Xing's departure alone made Li Yiting a little surprised, and Liu Xu'er was receiving treatment safe and sound at that time, so he continued to let Wan Yongkun and Fat Sheng follow Zheng Xing according to the original plan, and the others stayed to protect Liu Xu'er. This action finally saved Liu Xu'er's life, but the scene in front of her made everyone particularly confused.

After Wan Yongkun and Fat Sheng followed Zheng Xing out of the clinic, they found that he was just walking around casually, and did not find anything abnormal, nor did they see Zheng Xing contacting others, today's scene is exactly the same as following Zheng Xing before, that is, there is no problem at all.

On the other side, after Li Yiting revealed his identity, he got the cooperation of the dental clinic. He led everyone to conduct a thorough inventory of the clinic. Kuang Suo was mainly responsible for checking the layout of the clinic, as well as the situation in each room, the placement of equipment, and the position of the doctor and the patient at that time. Liu Zichen asked the clinic to retrieve the medical records of Liu Wuer, she found that a month ago, Yuan Hui'e did bring Liu Wuer to the clinic, and the doctor's diagnosis at that time was to extract the tooth, and the Liu Wuer was in a hurry to go to class and prescribed medicine, and then it may be that Liu Wuer's teeth did not hurt very much, or it may be that a lot of things happened one after another, and she did not come back, and she had to seek medical treatment until today when the pain was unbearable. In addition, Liu Zichen also found that the doctor who prescribed medicine to Liu Wuer last time and the doctor who performed surgery to extract Liu Wu'er today are not the same person, but the two of them gave the same diagnosis, which can only show that the doctor's diagnosis is correct, and none of the doctors will be suspected of misdiagnosis, nor will they deliberately lure Liu Wu'er to come. Xu Jingnan extracted the diagnosis and treatment chair where Liu Wu'er was sitting and some fingerprint traces nearby, and planned to go back to compare them, but he estimated that in such a public place, many people would touch these things, so it may not be of much significance. And Li Yiting asked Liu Xuer some questions, especially the situation of coming to the clinic today, he found that it was Zheng Xing who Liu Xuer took the initiative to find, and it was also the place that Liu Xuer took the initiative to ask to come, the time and place were not arranged by Zheng Xing, and this accident seemed to have nothing to do with Zheng Xing.

What's more, Zheng Xing left early in the morning, and everything in the clinic was very calm before he left, and the danger that Liu Xu'er encountered was in Zheng Xing's absence, if it was designed and arranged by him, how could he destroy the diagnosis and treatment instrument after he left? How could he happen to calculate that the nurse would hand the doctor the wrong scalpel? This is almost impossible, unless the doctor here is complicit with him.

After investigation, the doctor who operated on Liu Xu'er did not know Zheng Xing, today was the first time he saw it, and he and the people of the Liu family had nothing to do with Liu Xu'er before he came to see the doctor, and he did not have the slightest suspicion. Then this is strange, is there really a god of death who is manipulating all this? No one will be willing to believe this unfounded speculation anymore, but how to explain that Liu Xu'er is in danger again?

Chen Tianyu suddenly had a strange illusion, it seemed that all the efforts made by Beiting had not changed anything substantially, could it be that in this battle with the "Grim Reaper", Beiting would end up defeating?
