Chapter 120: Dentist

"There really is a carious tooth, and the hole is still there!" Zheng Guoqiang said.

"Check again to see if this bad tooth has been repaired recently." Lu Haoxuan said slowly. Zheng Guoqiang reacted immediately: "Ah? No way!"

However, his hands didn't stop at all, carefully checking the surface of the tooth crown. Sure enough, there were traces of new grinding on the enamel layer of this carious tooth!

After listening to the examination results reported by Old Zheng, Lu Haoxuan silently touched his chin and paced back and forth in the room, saying: "You Xinfa didn't seem to pay much attention to his external image during his lifetime, but from the furnishings in Yu Jiajia's home and the grade of the wine and food that night, it can be seen that You Xinfa was not a person who didn't care about the quality of life in private. Such a person, when learning that he had a carious tooth, would definitely repair it as soon as possible. Otherwise, his breath would be too heavy, and his little girlfriend wouldn't like it!"

Old Zheng listened to his analysis and was amused by his last teasing sentence.

The next day, Hu Jinquan's investigation results came out. You Xinfa had repaired his teeth at a famous dental clinic in the city, where he had always had medical records. According to the records, on the morning of the day You Xinfa had the accident, You went to the clinic to fill his teeth. The dentist who usually received him—the clinic owner Wang Deming—happened to have an outside visit and couldn't fill his teeth personally, so other doctors filled them for him. After filling his teeth, You Xinfa left, and no abnormal things happened during the period.

After listening to Hu Jinquan's words, Lu Haoxuan thought for a while and said: "Is there surveillance in that clinic?"

Hu Jinquan said: "I asked at the time. There is only one at the entrance of the clinic, and none are installed in other clinics."

Lu Haoxuan nodded and pondered for a while, then said: "Accompany me to the clinic. The problem must be with the tooth he filled!"

After learning that the task force had been made public, Gu Changzheng contacted Lu Haoxuan. His meaning was when he could return to normal work status. Later, the news he received was to continue to secretly carry out work under the status of being investigated.

Now that You Xinfa was dead, the new task given to him by the task force was to find a way to sneak into the New World and figure out the secret of the fifth floor.

Gu Changzheng received the new task and didn't know whether to laugh or cry. That place... sigh! If he were a woman, it might be easier to handle, but how could he dress up like a woman with his appearance!

He couldn't think of any good way for a while, so he thought about wandering around the New World to find an opportunity.

This wandering really helped him find a very good way to enter the New World!

Speaking of the master and apprentice Lu Haoxuan and Hu Jinquan, after arriving at the clinic, they retrieved the surveillance video of that day and checked it carefully. At 10:00 AM that day, You Xinfa appeared in the surveillance video. At 10:15 AM, they saw the clinic owner Wang Deming leave the clinic. He should have exchanged a few pleasantries with You and arranged for other doctors before leaving. This was also reasonable. After all, with You's status, Wang Deming couldn't neglect him.

After another hour, they saw You Xinfa appear in the surveillance again. This time it was clearly leaving the clinic, and then the video played until the clinic got off work that day. Except for the doctors, nurses, and patients who came that day, they didn't see anything abnormal.

However, Lu Haoxuan always believed that the problem was in the clinic. After watching the video, Lu Haoxuan turned Wang Deming's office into a temporary interrogation room...

Wang Deming was a stomatological expert renowned in Zizhen City. He resigned from the City Stomatological Hospital very early and founded this private dental clinic. From the 1990s to the beginning of the new century, there were basically no ordinary people who could pay much attention to oral problems (this refers to the care of the mouth and the prevention of diseases, not the treatment of oral diseases when they appear).

So Wang Deming originally had some complaints about Lu Haoxuan's approach. But when Lu Haoxuan asked clearly about the personnel situation in his clinic and checked the number of patients who visited that day, he unexpectedly found that there was an extra doctor not on the register in the video. Wang Deming panicked a bit. He knew You Xinfa's status. Although he didn't know what had happened now, seeing Lu Haoxuan come to investigate personally and finding an unidentified person in his clinic really made him worry!

Lu Haoxuan called all the medical staff in and checked their identities one by one, confirming that the registered personnel in the clinic were all present! Clearly, the problem was with that "extra" doctor!

And Wang Deming confirmed that his clinic hadn't recruited any new doctors or nurses during this period. Lu Haoxuan asked Hu Jinquan to sort out the medical staff and the patients who visited that day, and then watch the surveillance video of that day from beginning to end again.

After watching this, they really saw the problem. All the personnel entering and leaving the clinic that day—when there was one extra medical staff member in the video, there was one less patient!

"Heh heh!" Lu Haoxuan sneered. He knew what trick the other party had used!

The other party first entered the clinic as a patient with other patients, and then when others weren't paying attention to him, he quietly changed into the white coat of the medical staff here in the clinic's bathroom. Then, during You Xinfa's treatment, he fabricated a lie to send away the doctor who was filling You Xinfa's teeth, and then used this time to mix in and replace the original filling material with the poison pill he had prepared!

And You Xinfa, who was lying on the dental chair, generally wouldn't look up at the dentist behind him, and the timing chosen by the killer must have been after the real dentist had cleaned the carious hole and was tricked out of the treatment room!

To verify his deduction, Lu Haoxuan called the doctor who filled You Xinfa's teeth that day again. This doctor surnamed Liu thought for a while and suddenly realized: "Oh, I remember now. In the process of filling Branch Chief You's teeth that day, I did receive a phone call. The other party called my name directly, but after beating around the bush for a long time, I found that the person the other party was looking for wasn't me at all. I don't know how it got to me!"

Lu Haoxuan asked: "Do you have a mobile phone? Where is the phone? You haven't deleted that number that called in, have you?"

Dr. Liu took out a new Nokia mobile phone from his pocket and handed it over. Hu Jinquan reached out and took it. Dr. Liu said: "I haven't deleted it yet. It's a mobile number in this city."

Lu Haoxuan signaled Hu Jinquan with his eyes to check the owner of this number, then flipped through the phone. The call time on it was actually 4 minutes and 50 seconds! He showed the phone displaying this call time to Dr. Liu. Dr. Liu hurriedly explained: "Officer, I really don't know who the other party is. He chatted with me for a long time, and only after saying a lot of ambiguous words did I realize he had dialed the wrong number."

Lu Haoxuan laughed: "Don't be nervous. Think again, after you answered the phone and came back, was there anything different about You Xinfa? Or was there anything different in the clinic?"

In the reasoning just now, he didn't consider that this doctor was tricked out by a phone call, but this confirmed the time the killer could use. ===== CHAPTER 121 =====
