"What are the specific bases for what you say??"

Xiao Rongzheng frowned, stood on the edge of the whiteboard, hugged his chest with one hand and supported his chin with the other hand and asked.

"It can be concluded that both victims died from the air needle, and this type of modus operandi requires a high level of knowledge and modus operandi of the murderer. In other words, if a small amount of air accidentally enters the intravenous infusion, it will not cause harm to the human body. IT IS VERY UNCOMMON TO HAVE AN INCIDENT DEVICE THAT CAN INJECT 100ML OF AIR AT A TIME, WHICH MAY HAVE BEEN DELIBERATELY MADE BY THE MURDERER HIMSELF. Therefore, the murderer must have a medical background, even if he is not a medical professional. ”

Cheng Han paused, took the water cup handed over by Xu Ranran, took a sip, and continued.

"As for the rest, I suggest you go to the 'Supreme' entertainment club where the two victims work, but it's best not to be alarmed and keep a low profile. But be quick, maybe the killer has already locked on to the next target. ”

Dr. Cheng is right, at present, the murderer did not commit an impulsive crime, but had a purpose and plan. However, the entertainment club of 'Supremacy' has some black backgrounds, and it is very strict from top to bottom. A week ago, our colleagues did not make any breakthroughs. Xiao Rongzheng sighed, he had lost a lot of hair every day since last week, if there were no clues, he felt that he was going to be 'overwhelming'.

Cheng Han stood beside him, silently looking at his anxious look, "I'm a VIP there, if Officer Xiao doesn't mind, I can cooperate with you in disguise investigation." ”

"That's great!" Xiao Rongzheng raised his head and looked at Cheng Han with bright eyes, as if to express his gratitude, he pulled out a big smile from the corner of his mouth and gave it to her.

Cheng Han, who was accustomed to seeing the serious Officer Xiao, only felt goosebumps on his arms, and shivered unconsciously.

"Xu Ranran, you and Lao Xie go to the Second Prison to contact the suspect three months ago to see if it can be related to this case, and get in touch with them. Dr. Cheng, please wait for me, and we will set off for 'Supremacy' immediately. ”

After Xiao Rongzheng finished speaking, he went to the dressing room next to him to change into civilian clothes and asked Cheng Han to wait for him at the door.

Xu Ranran was still a little uneasy before leaving, she poked Cheng Han who was in a daze and said, "Ah Han, our boss is actually quite good, but sometimes, for the sake of the case, his temper is not very good, his attitude is a little fierce, his mouth is a little bad, you see how crazy he laughed just now." You have to bear more, we can do harm to the people. If he upsets you, come back and tell me, I'll let my dad clean him up! ”

Cheng Han looked at Xu Ranran's worried look, stood on tiptoe, touched the girl's short hair, and said with a smile, "I know, our director is a daughter, and I promise that he won't dare to bully me." Don't worry, everyone is on business, and he won't be embarrassed for me as a girl. ”

Xu Ranran nodded, and then quickly followed Xie Wencong's pace with confidence and walked out of the police station. Cheng Han leaned against the wall like this, looking down at his shoes in a daze.

There was a sudden silence around, except for the branches rustling in the wind on the tall poplar trees outside the window. After a while, the door of the locker room opened, and Xiao Rongzheng changed into a police uniform, wearing a somewhat close-fitting white T-shirt inside, and a dark gray shirt as a jacket outside his arms. The black cargo pants with many pockets are paired with the same black Martin boots as Cheng Han, which line the already slender legs and are longer.

The man looked at the girl in front of him who only glanced at him and then turned his gaze to look outside, and shook the car key in his hand a little uncomfortably, "Let's go." ”

After speaking, he walked out with long legs, and didn't see if Cheng Han had followed.

It wasn't until Cheng Han trotted all the way to the door that he saw Xiao Rongzheng standing on the side of a red Mercedes-Benz big G and looking left and right, and when he saw Cheng Han coming up, he asked a little excitedly, "Dr. Cheng, is this your car?" ”

Cheng Han nodded and threw the key to Xiao Rongzheng, "You can open it." As he spoke, he sat in the passenger seat.

Xiao Rongzheng took the key, sat in the driver's seat with long legs, and then began to adjust the seat space to the maximum, and did not forget to explain to Cheng Han while adjusting.

"I originally wanted to drive a police car, but then I thought, aren't we investigating in disguise! In addition, Dr. Cheng, you are still a VIP, we are not allowed to drive a car with open spots, worthy of VIP status, so that people can find clues. What do you say, Dr. Cheng! ”

Cheng Han only said 'um', feeling that the man next to him had a lot of words, so he closed his eyes and ignored him. When Xiao Rongzheng saw the girl like this, he closed his mouth in a funny way, concentrated on driving, and stopped talking.

There was a faint smell of citrus in the car, which seemed to add a little life to this somewhat withering autumn.

As the car drove along, the tall buildings on both sides of the road were quickly thrown behind them. Without the obstruction of high-rise buildings, the field of vision is getting wider and wider. Their car drove into a mountain, and a winding road was the only way in and out. There are only verdant pines and cypresses on both sides of the road, the occasional bird call, and the sound of gurgling water. Close your eyes, as if you can wash away the hustle and bustle of the city.

At the end of this winding road is a palatial European-style manor house, reminiscent of the residence of a European aristocrat in the Middle Ages. The iron gate at the gate was closed tightly, as if to say, 'Idlers are not allowed to enter'.

Xiao Rongzheng parked the car in front of the door and turned his head to look at Cheng Han. I saw her hand over a golden card, and then pointed to the sensor with a red dot on the iron door, "Put the card on it!" ”

As soon as the card was pasted, the door clicked open. Seeing the door open, Cheng Han glanced at Xiao Rongzheng meaningfully, and instructed, "Officer Xiao, you have to cooperate in a while!" ”

Xiao Rongzheng nodded with a serious expression, Cheng Han looked at him like this, but he felt inexplicably funny. Seeing Xiao Rongzheng looking over to her, she hurriedly put her hand on the window frame, held her cheeks, and turned her head to look at the scenery outside the car.

As soon as you enter through the iron gate, there is a musical fountain pool made up of several statues of cherubs, and around this fountain pool is the entrance to the reception hall. Xiao Rongzheng parked the car at the door, and the polite, neatly suited waiters came over to open the car door, stretched out his hand to block the door frame, and invited them down. Cheng Han motioned for him to give the gold card in his hand to the waiter, and the man took it and looked at it, walked to the side and said something on the walkie-talkie. Another waiter took the car keys and helped them drive it to park. The two of them walked into the reception hall, and as soon as they entered, they felt dazzling, and when they looked at it, almost everything was golden.

"What kind of service do you two need?" A beautiful waitress dressed in a tailor-made cheongsam with a smile came over and asked.

"Meal." Cheng Han said, stretched out his hand to grab Xiao Rongzheng's arm, leaned his head on his arm affectionately, and said coquettishly.

"Ah Rong~ People think it's boring for two people to eat, and they want a beautiful young lady to accompany them. The ancients said that the beauty is delicious, and with a beautiful young lady by her side, people will definitely be able to eat an extra bowl of rice. Xiao Rongzheng looked at the little girl who was hanging on her arm, tilting her head, and being coquettish like a kitten, and quickly entered the role. He took her in his arms and said to the waiter boldly.

"Do you hear that, invite your most beautiful young lady over, and open another bottle of good wine for us to send to the private room." After speaking, the two hugged each other and walked to the private room under the guidance of the waiter in front of them.

The waiter was well-trained and smiling the whole time, and seemed to be used to it all. Ordinary people can only eat and drink when they come here, and then do a SPA or something. Only Silver and Gold members can slowly open up their privileges and enjoy some services that ordinary guests don't have. Of course, the level of waiters received by members of different colors is also different.

The two of them had already come to the outside of the private room, and the waiter politely invited the two in, bent down and bowed.

"The meal will be fine in a while, I'll help you open a bottle of wine first, and the person you want will come over to accompany you two immediately." After saying that, he bent down and took three steps back, and then turned around and left.

At this moment, there were only two people in the private room, Cheng Han and Xiao Rongzheng, and Cheng Han had already let go of the hand holding the man's arm and sat by the window. She picked up the teapot and poured two cups of tea, one was held by herself and drank slowly, while the other cup was handed to Xiao Rongzheng. Xiao Rongzheng took the tea, sat next to the girl, opened his mouth to say something but didn't know how to speak, he could only scratch his short inch with some irritability, and drank the tea in the cup.

The freshly brewed tea was still a little hot, Xiao Rongzheng felt that there was no skin on his tongue, so he covered his mouth and secretly sighed outside, but his face was silent.

Cheng Han drank the tea in his hand like this, and reached out to put a napkin in front of Xiao Rongzheng. The footsteps outside the door were getting closer and closer, Cheng Han put down the teacup, leaned on Xiao Rongzheng like he had no bones, and picked up the napkin just now to help him wipe the tea from the corner of his mouth.

"Dangdang Dang"

"Come in!" Xiao Rongzheng adjusted his posture and hugged Cheng Han, who was glued to him, in his arms, before letting the people outside the door come in. The door opened, and two women of different styles walked in with two bottles of Rémy Martin.

The woman walking in front of her was perming the curly waves, the big red tight-fitting hip-wrapping dress showed beautiful curves, and she stepped on nearly twelve centimeters of black strappy high heels, and walked over and sat next to Xiao Rongzheng.

The other woman wore only a long-sleeved white chiffon dress with a square neckline, and her silky black hair was scattered casually, as if out of a medieval oil painting. She glanced at the situation in the room, deliberately went around, and sat next to Cheng Han.

The red-clothed one took the lead in pouring wine into the wine glass, leaned forward, and handed his hands in front of Xiao Rongzheng. Xiao Rongzheng leaned back without a trace, only feeling that the smell of this woman's perfume was a little pungent, but he coped, "Thank you!" You drink too. ”

On the other side, Cheng Han was still leaning on Xiao Rongzheng, lazily reaching out to take the wine glass in the hand of the woman in white, taking a sip, and lightly reaching out to grab a handful of hair on the woman's shoulders, circling it between his fingers.

"This sister is so beautiful, what's your name?"

"My name is Kikyo."

"Sister Kikyo is probably the most beautiful here, and sure enough, seeing good-looking people has a much better appetite. You say yes, Ah Rong. Hearing Cheng Han call himself, Xiao Rongzheng nodded and said yes, and did not forget to get close to Cheng Han after speaking.

I secretly felt that the citrus smell on Dr. Cheng's body was much better than this woman's overly strong perfume smell.

And the woman in red was unwilling to be noticed by the bellflower, so she couldn't help but interject.

"Little girl, she's not the best-looking of us. Our best-looking sister here is called Liu Yiyi, but she hasn't been here for a few days. When Xiao Rongzheng heard this, he secretly used force to hold Cheng Han's hand. Cheng Han just ignored him, still playing with Kikyo's hair while drinking. Xiao Rongzheng could only pinch her shoulder lightly, give herself a sigh, and then speak.

"Liu Yiyi? We have been here so many times, and we are all received by Mei Mei, where did Liu Yiyi come from. If you want me to see, my dear is right, the bellflower must be the best looking you have here. ”

The woman in red said with a frightened expression when she heard Mei Mei's name.

"I'm afraid you haven't been here for a few days, seeing that you two are also frequent visitors to Meimei, I'll tell you the truth." The woman looked at the door and said in a low voice. "Mei Mei, dead."

Xiao Rongzheng sighed and expressed pity. And Cheng Han, who had been drinking with the bellflower, suddenly became interested when he heard this, poured a glass of wine for the woman in red, and asked.

"Sister, there's a question I've always been curious about. You say, Sister Meimei's face is so good-looking, is it possible that it is fake? After saying that, she looked at the woman innocently, and her face was full of curiosity.

The woman wanted to speak and stopped, looking very embarrassed. Cheng Han smiled, took out a checkbook from his sweatshirt pocket, wrote it casually, held it in his hand and shook it at the woman.

"Sister, just tell me~ This is for you as a tip. People just see that you are so beautiful, and they want to fix it! The woman took it, saw the words 50,000 written on it, and nodded.

"Girl, don't talk nonsense, your original clothes are better than our modifications, I don't know how much, don't laugh at us! However, in our business, if we want to go up, we have to move a knife somehow. Speaking of which, Meimei's hospital was introduced by me. You see that as soon as she finishes the whole thing, it will be different immediately. The reception is also a gold card guest, but unfortunately it is a little shorter. The woman hid the check between her twin peaks, picked up her glass, and took a big sip. Cheng Han reached out and touched the cup with her, and sighed a little regretfully.

"Hey, speaking of which, I came over to play with Sister Mei a month ago, but the two of us went on a business trip abroad and didn't have time to spare. I thought I would be able to see her again when I came back from abroad, but who would have thought. Hey, that's a shame. After saying that, she drank all the wine in the cup, and Kikyo, who was sitting on the side, poured her another full glass with a very eye-catching look. Seeing that she still wanted to send it to her mouth, Xiao Rongzheng hurriedly grabbed her hand holding the wine glass.

"Well, don't drink so fast just yet. Don't you want to eat the bad fish fillet here, and then drink it after the dish is served? Xiao Rongzheng put the wine glass on the table, and easily brushed the strands of Cheng Han's broken hair scattered around his ears behind his ears.

"People are just sad, they haven't been able to see Sister Mei in the end. I don't know who was so lucky to see Sister Mei for the last time. Cheng Han hugged Xiao Rongzheng's neck with both hands, buried his head in his chest, and complained coquettishly.

Xiao Rongzheng felt the girl's warm breath tickle on his chest, and his face began to turn red slowly, but fortunately, his skin was darker and not very obvious. He hugged Cheng Han and gently patted her on the back, comforting her softly.

The two women sat next to them and were a little embarrassed, this was the first time they had encountered a situation where the accompanying guests cried. The woman in red rolled her eyes and opened her mouth to comfort, "Girl, don't be too sad. I heard that the last person Mei Mei went to see was also a regular customer, who seemed to be called 'Red Rooster'. I don't know what it does, but it's quite rich anyway. ”

"Rich? I have money, too! Cheng Han sniffed in Xiao Rongzheng's arms, took out the checkbook in his pocket and shook it.

Several people were amused by her innocent appearance, and Xiao Rongzheng took a napkin to help her wipe her nose. And the door of the private room opened again, and the waiters walked in with steaming, fragrant dishes. The previous depression and unhappiness were swept away by the food and wine at once, and the private room began to push and change the glasses.

Cheng Han's face was flushed, and he staggered behind Xiao Rongzheng with the support of the two beauties in a drunken daze, and waited until Xiao Rongzheng opened the door of the room before taking her from the hands of the two beauties.

"Please go back, we will pay the service fee as usual, she is very happy today, thank you!" As he spoke, he took Cheng Han into the door, and with a 'snap', he closed the door cleanly.

The two outside the door just shrugged their shoulders and glanced at each other. At the dinner, I knew that these two were moody, and their tempers were no better than ordinary people, but they were really generous. And you can get money without 'service', so why not. So the two of them left the door quickly, for fear that the people in the house would regret it.

In the room, Cheng Han, who was still drunk and couldn't even walk just now, opened his eyes suddenly, got rid of Xiao Rongzheng's hand, and went straight to the bathroom to wash his face.

"Officer Xiao, did you find anything this night?"

Cheng Han, who had washed his face, came out of the bathroom and asked while wiping his face with a towel.

"Mei Mei's last guest before her death, the one called 'Red Rooster' is very suspicious." Xiao Rongzheng handed a cup of hot water to Cheng Han.

"Thank you, and just now Kikyo told me that 'Red Rooster' not only looked for Meimei, but also looked for Liu Yiyi, and also came to her two days ago." After drinking a few sips of hot water, Cheng Han felt more comfortable in his stomach.

"And when did you find out?" Xiao Rongzheng was surprised.

"She accompanied me when I went to the bathroom. Girls go to the bathroom in groups, and it's often easier to share secrets at this time. ”

"Dr. Cheng, just tell the truth, how much money it spent." Xiao Rong looked at her narrowly.

“…… 50,000 ......"

"It's really generous, Xiao admires." Xiao Rongzheng smiled a little. Cheng Han only felt that this man's words were full of sarcasm, especially at this moment, the smile on his face was particularly dazzling.

She took another sip of water, cleared her throat, and said to the man who was laughing happily, "Disguise yourself as a detective, of course, you have to enter the role." Moreover, it is all my own money, and I don't need to be reimbursed by the bureau. ”

She drank the rest of the water in one go, and when she saw that the man was still there covering his mouth and laughing, she suddenly felt an inexplicable unhappiness in her heart, "Officer Xiao will continue to laugh if he doesn't want to walk back by himself now!" ”

Sure enough, the laughter stopped abruptly.

Xiao Rongzheng looked at Cheng Han's face and immediately apologized, "What Dr. Cheng said is right, I didn't mean to. ”

"It's okay, you better send what you just found to the bureau and let them prepare first. It's nothing, I'll go to sleep first. Cheng Han poured himself another glass of water, and with the water, he was about to walk to the guest bedroom inside.

"Dr. Cheng!" Xiao Rongzheng suddenly shouted at her behind her back.

"What else is going on with Officer Xiao?"

"Well, I apologize for those rude things I said to you today. I'm not a good talker, and sometimes I'm in a hurry for the case, which offends you, but I really don't mean anything else! ”

The man grabbed his head a little crampedly, not daring to look at Cheng Han. Cheng Han looked at the tall man in front of him and smiled. Such a person is actually quite easy to have a good impression, work hard, be sincere, and know that mistakes can be changed.

"It's okay, then, happy cooperation in the future!"

"Happy working together!"
