Chapter 121: Undercover

Dr. Liu lowered his head, pondered for a while, and then raised his head: "Nothing special. It was my first time filling Branch Chief You's teeth, and I didn't know his habits very well. I remember when I returned to the clinic, Branch Chief You was lying on the dental chair with his eyes closed, and he didn't say anything to me, so I continued to fill his teeth."

Lu Haoxuan said, "What material did you use to fill his teeth?"

Dr. Liu replied: "For Branch Chief You, we used composite resin material. This is a material our clinic has only recently started using. The price is relatively expensive, but it is more beautiful and the same color as the teeth."

"Heh heh!" Lu Haoxuan laughed: "Then what are the disadvantages of this material?"

"This, well, it's okay. The wear resistance is a bit worse, and it's a bit more expensive."

"Then did Branch Chief You say anything to you after filling his teeth? For example, what should he pay attention to?" Lu Haoxuan pointed to a promotional picture hanging on the wall showing a mouthful of white teeth.

"Oh, I took the initiative to tell him, which is to avoid chewing hard objects, and it's best not to drink alcohol or avoid strenuous exercise that day, and to come for a follow-up visit if he feels uncomfortable." After Dr. Liu finished speaking, he added somewhat worriedly: "Can I ask what happened to Branch Chief You? Filling teeth can't even be considered a surgery. Nothing happened, right?"

"You don't need to ask about this. Alright! Thank you, Dr. Liu. You can go out first." Lu Haoxuan said.

Little Dr. Liu left the office somewhat uneasily. Then, Criminal Police Officer Xiao Zhang, who accompanied Lu Haoxuan, called Wang Deming in.

Lu Haoxuan proposed to take away the remaining composite resin material used by Dr. Liu to fill You Xinfa's teeth that day, but Wang Deming looked embarrassed. Lu Haoxuan said: "What? Can't you distinguish it?"

Wang Deming nodded and said: "Yes, you also know that this material has just become popular in the market, and many patients are using it..."

Lu Haoxuan said angrily: "Think carefully! That material is very likely to have been tampered with! If something happens, you can't afford to bear it!"

He was worried that the killer had omissions when mixing the poison pill wrapped in potassium cyanide into the dental filling material, which might cause innocent harm!

Wang Deming was startled by Lu Haoxuan's sudden change in attitude! "It seems my guess is right. Damn it, how can something happen just by filling a tooth?" he cursed secretly in his heart!

"Captain Lu, don't get angry. Let me think, let me think." He said hurriedly. But fortunately, not much time had passed, and not many people had filled their teeth. Soon, Wang Deming brought over the composite resin material used in the past few days.

Lu Haoxuan looked at the several tubes of material that were clearly used and asked: "Is this all of it?"

Wang Deming nodded hurriedly: "The ones that have been opened are all here. The dosage of this thing is relatively small each time, and this tube can be used for a period of time."

Lu Haoxuan nodded, and Xiao Zhang beside him took out an evidence bag and packed the several used materials separately. At this time, Hu Jinquan walked in hurriedly. He walked to Lu Haoxuan's side and said: "Master, the number that called Dr. Liu has always been in a powered-off state. After checking with the mobile company, the owner of the number is a college student. After contacting the school, it turned out to be someone who lost their ID card!"

"Heh heh!" Lu Haoxuan sneered: "The method is consistent!"

It seemed there were no other clues here for the time being. Lu Haoxuan asked as if remembering something: "Dr. Wang, who was your outside visit client that day?"

Wang Deming was stunned for a moment, not knowing whether he was surprised by the question he asked or if it was inconvenient to answer. He hesitated and said: "This..."

Lu Haoxuan laughed: "What? You are only solving oral problems here. This shouldn't be any privacy that is hard to talk about, right?"

When Lu Haoxuan said this, Wang Deming felt a bit embarrassed. He laughed: "No, it's Director Guo from the City Bureau. He made an appointment for me to give him a dental check-up."

"Oh!" Lu Haoxuan responded lightly and didn't ask any more. After saying goodbye, several people left the clinic.

"Master, what do you think?" In the car, Hu Jinquan asked.

"Hmm?" Lu Haoxuan seemed a bit distracted: "Oh! Now it can be determined that the killer used the time You Xinfa was filling his teeth to pre-bury a poison pill for him. The person who did it was just a lackey." Lu Haoxuan said while looking at the car window intently, as if he could find the suspect somewhere.

"Then regarding the arrest of this suspect, do you think we should deploy it immediately?" Hu Jinquan asked.

Lu Haoxuan withdrew his gaze and looked at Hu Jinquan: "You deploy it immediately. Focus on checking the video of people following You Xinfa when he entered the clinic or entering the clinic after him. The killer went in at that time. Finding him will yield more gains!"

Hu Jinquan nodded and silently calculated how to deploy the arrest plan.

Speaking of Gu Changzheng, after receiving the task of sneaking into the New World, he wandered to the New World this day, wanting to find a way to mix in, but saw a recruitment advertisement posted on a welcoming sign outside the main gate.

They were hiring an electrician here! Gu Changzheng was happy. Wasn't this just prepared for him?

He tidied up his sleeves so that he wouldn't look so sloppy, and then went up to ask the security guard on duty at the door.

After successfully passing the so-called interview, Gu Changzheng secretly rejoiced. It seemed that his usual hobby of tinkering with electrical circuits had brought convenience to his work.

The next day, in the afternoon, he came to the New World Entertainment City, and the squad leader of the electrician squad took him to the basement to familiarize himself with the environment of the master control room.

Gu Changzheng saw that the power control systems for each floor were separate. The control boxes for the first to fourth floors were marked, but the control box for the most mysterious fifth floor was missing. Gu Changzheng pretended not to know and asked: "Squad Leader Liu, isn't our New World five floors in total? Why don't I see the control box for the fifth floor? If there is a problem with the electricity on the fifth floor, how do we handle it?"

The squad leader surnamed Liu was over 50 years old and wore thick glasses all day because of nearsightedness. Privately, he was called "Glasses Liu." He heard this and showed an unfathomable expression: "You don't know this, right! The fifth floor has a separate control room. We don't need to worry about things there. We just need to manage the affairs of these four floors!"

"Oh! Is the fifth floor rented to someone else separately? I thought it was one family?" Gu Changzheng showed a look of thinking he was smart.

Squad Leader Liu hummed: "You know a fart! In this Zizhen City, who can open a business above Boss Chang? You're really a country bumpkin. The fifth floor is naturally Boss's business!"

Gu Changzheng deliberately provoked him: "Then why is it managed separately? Squad Leader Liu, is it not trusting you?"

As soon as Glasses Liu heard this, he became unhappy and said angrily: "What do you know? I've been following Boss Chang for five or six years, and that fifth floor is..." ===== CHAPTER 122 =====
