This regulation seems to be able to put an end to the confusion of people in the housing area, but in fact there are still too many loopholes, but it is entirely possible for ordinary people with bright brains to blend into the guest room area above the sixth floor without a room card. To put it bluntly, this thing is the same as a door lock, it can lock the gentleman, but it can't lock the villain.

In order not to arouse the vigilance of the hotel, they did not ask to live next door to Lu An, but when booking the room, they chose the same suite type as Lu An, and were arranged by the hotel on the same floor of the room booked by Lu An.

After getting the room card, the group came to the room on the seventeenth floor, which was quite high-spec, not only with four bedrooms, but also a simple reception room and meeting room, which belonged to the multi-functional suite.

"Room 1702 booked by Lu An is not far from our 1706, and the receiving distance of wireless devices is enough!" Qu Liuqiao took out the equipment from his backpack and asked while tidying it up, "Team Xiang, I won't open this kind of door lock for swiping the card to unlock the ban, how are you going to put these devices into room 1702?"

"Contact the hotel manager in the name of the city bureau, ask him to sign a confidentiality agreement, and then get a universal key card!" Xiang Yu took out his mobile phone and prepared to call the city bureau to report.

"Don't yet!" Tang Tian hurriedly stopped, after the investigation of the previous cases, especially the old policeman who crossed Wang Wen and directly arranged the burning of the suspect's body, he was very uneasy about the city bureau.

"Hmm, what do you think?" Xiang Yu is still very willing to listen to other people's opinions at this point.

Tang Tian didn't answer directly, but pointed to the vent above his head, as soon as he entered the room, he began to check the vent, as he expected, the ventilation ducts on all floors had not been replaced.

"I have observed the ventilation duct on the first floor, this old-fashioned pipe is enough to accommodate an adult man to crawl through, we don't need to alarm the city bureau and the manager of the hotel, this kind of secret control work, the fewer people in the know, the less likely it is to leak the news!" Tang Tian directly moved a chair, stepped on the chair and removed the air filter at the vent of the ventilation duct.

The mouth of the pipe in front of him was barely able to accommodate Tang Tian to climb in, Tang Tian supported both sides of the pipe with both hands, jumped upward, and most of his body entered the mouth of the pipe, only to find that the inside of the pipe was more spacious.

"Can it work?" Xiang Yu asked with some concern.

Tang Tian's whole person got into the ventilation duct, he looked inside, tried to move back and forth for a distance, and then poked his head out of the vent and replied: "It's not a big problem, there is no noise from the motor in the pipe, it should be that there is no relay fan installed!"

Seeing that Tang Tian was so sure, Xiang Yu also agreed to his plan, asked Qu Liuqiao to prepare the equipment, and cooperated with Tang Tian to enter room 1702 to install monitoring equipment.

The whole process was much smoother than expected, perhaps because of the high housing prices, or perhaps because of Lu An's face, there were no tenants in Room 1702 at present, and Tang Tian quickly installed the necessary monitoring equipment in every room of Room 1702.

After climbing back from the pipe, the signal detection was normal, and Tang Tian restored the vent filter to its original state.

"Okay, the preparations are basically complete, and we haven't eaten dinner yet, let's go to the restaurant downstairs to have a good meal!" Xiang Yu personally checked the network connection, and after making sure that there was no problem, a long-lost smile appeared on his face.

"Meal reimbursement?" Jia Zuozhen likes this kind of thing the most, he will not miss the reimbursed meal, and he is the one who eats the most and lasts the most.

"Reimbursement!" Xiang Yu nodded affirmatively, "Everyone has worked hard in the past few days, and it can be regarded as a reward for everyone!"

Since the public expense was reimbursed, Tang Tian, who was going to sleep directly, also felt that he would not eat for nothing, not to mention that the meandering stream itself was weak and gourmet.

The group came to the restaurant on the third floor with a smile, Xiang Yu just finished ordering and sat down, he unconsciously twitched his nose a few times, looked at Tang Tian, and asked in a low voice, "Tang Tian, do you smell anything?"

"Fragrance!" Jia Zuozhen said first, with a salivating look, "And it's a very fragrant fragrance!"

"It's the aroma of mushroom soup!" Qu Liuqiao remembered the taste of mushroom soup very well, and immediately reflected it.

With the determination of Qu Liu's weakness, Xiang Yu's face became strange, he was now extremely glad that he did not notify the manager of the hotel, the fragrance of mushroom soup is enough to prove that this hotel is more or less sure that there is a connection with the Meridian Meeting, if the hotel manager is notified just now, it is basically equivalent to notifying the Meridian Meeting!

"Bring me the menu and I'll take a look!" Before everyone was looking at me and I was looking at you, Tang Tian had already responded, he took the menu from Qu Liuqiao's hand, and carefully studied all the dishes related to mushrooms.

There are many mushroom-related dishes on the menu, but there are only two mushroom-related dishes, dry fried mushrooms and chicken mushroom crockpot soup.

"Handsome guy, please come here!" Tang Tian beckoned to the waiter, and when the waiter walked to the table, he pointed to the menu and said, "Add us a dry fried mushroom and a chicken mushroom crockpot soup!"

"Okay, wait a minute!"

Seeing the waiter walk into the back kitchen, Tang Tian's eyes were slightly cold, and he was thinking about how to enter the back kitchen to check.

The kitchen of the star-rated hotel cooked very quickly, and a few people did not wait for a long time, and a table of dishes was brought up one after another, but everyone did not move their chopsticks, but swept these dishes back and forth with scrutinizing eyes.

"Except for the dry fried mushrooms and the chicken mushroom crockpot soup, there are no mushroom ingredients visible to the naked eye in the other dishes, but all dishes have the unique aroma of mushroom soup!" Qu Liu's weak nose was the sharpest, and she immediately made a judgment, "Then, it can be preliminarily ruled out that the hotel has fresh corpse mushroom suppliers, they should use dried mushroom powder ground by Dapeng!"

"That stronghold in Dapeng has long been destroyed by us, and the hotel has to cook every day, and there must be a lot of consumption of mushroom powder. That is to say......"

"There are other mushroom processing bases in Angang City in the Meridian Society!" Tang Tian's face showed a smile, this clue came too unexpectedly! If you touch it along this line, it is very likely to be a big fish!

"Check!" Xiang Yu immediately made a decision, he looked at Tang Tian and Jia Zuozhen, "This time, you two are in charge, find a way to mix in the back kitchen, figure out what seasoning the mushroom powder is mixed in, and then find the supplier along the vine!"

Jia Zuozhen felt a little bitter in his mouth, but he still nodded and agreed: "Okay, but I am born with a lack of gold, and I am born to work hard!"

"Come on! As for your virtue of being abducted and deceived in the early years, I think you are congenitally lacking in virtue! Joining the Special Investigation Bureau is your journey of atonement!" Xiang Yu also began to improve his mood and joked with Jia Zuozhen.

"Good, good, atonement for sin, atonement for sin, serve the people, not hard!"

With the new direction of investigation, everyone's mood suddenly relaxed, the physical fatigue was swept away, and the meal was naturally eaten faster.

After eating and drinking, Tang Tian glanced at his mobile phone, it was already half past eleven, and he couldn't help but glance at Jia Zuozhen: "Old Jia, don't eat! The back kitchen should be about to get off work, let's get ready to start work!"

Jia Zuozhen swallowed the last piece of fat, and then reluctantly grabbed the tissue and wiped the oil flowers hanging from the corners of his mouth: "Don't worry, I may not be able to help you with anything else, but playing tricks with others is almost like playing routines, I, Jia Banxian, am a top guy!"

Coming out of the restaurant, the group of soldiers divided into two ways, and Qu Liu weakly pushed Xiang Yu back to room 1706, although Lu An had not yet arrived, but the monitoring of room 1702 had begun, and it might be possible to find the method of controlling the phone explosion of the meridian meeting through monitoring.

Tang Tian, under the leadership of Jia Zuozhen, found a staircase in the passage leading to the back kitchen of the Chinese restaurant and pretended to be standing by the window to smoke, and waited patiently.

didn't let the two of them wait long, and when it was early at twelve o'clock in the night, people came out of the passage one after another.

After waiting patiently for more than ten minutes, the flow of people gradually became scarce, at this time, Jia Zuozhen suddenly stood up, he walked quickly to a middle-aged man, with a courteous smile on his face: "Hehe, you are Master Qin, right? Hey, hey!

"Who are you? How do you know my surname is Qin?" The middle-aged man who was stopped had a cold face and looked around vigilantly, looking like he wanted to open his mouth and call for security.

"Don't don't, don't get excited!" Jia Zuozhen hurriedly smiled and took out a pack of soft Chinese from his pocket, quickly unpacked it, handed it to the middle-aged man and lit a fire for him at the same time, and even stuffed the cigarette case into the middle-aged man's hand, "Don't be excited, my relatives introduced me to you, hehe, I opened a small restaurant, but the food I invited the cook to cook was too unpalatable, my relatives said that you are one of the best chefs in Angang City, I don't want to find you to learn from it!"

The middle-aged man relaxed slightly, and Jia Zuozhen's words were not obvious sycophants that made him very comfortable to listen to.

"Who are your relatives? don't listen to his nonsense, what kind of master am I, that is, thanks to Manager Wang's care, I can barely eat!" Master Qin's face was full of smiles.

"Hehe, you're humble, you're so humble!"

Jia Zuozhen looked like he bowed his head and waist, only mentioned his relatives, and just continued to pat himself on the back: "I've tasted the dishes you made, hey, hey! That taste is a must! Ordinary materials, the taste made in your hands is just one word, Xian'er! If you don't mind, I want to hire you as a food consultant for our restaurant, you don't have to go to work on weekdays, just give some guidance to our chefs, don't ask them to learn one percent of yours, one thousandth, that's my honor!"

Look, this sycophant, Tang Tian stood to the side and his face was flushed, if he wasn't investigating the case, he really wanted to lie on the ground with his stomach and laugh for a while!
