Tang Tian's head suddenly buzzed, Xiang Yu had sent a text message to himself before to inform Lu An of the temporary change of room, but he didn't say that he wanted Qu Liuqiao to pretend to be a waiter to reinstall the listening equipment!

In an impatient mood, Tang Tian's right foot stepping on the accelerator unconsciously increased a few points.

When Tang Tian rushed back, Xiang Yu had already decided to give up covert surveillance, and he contacted Wang Wen to ask for manpower, preparing to directly reveal his identity and enter the 1901 suite, and ordered Lu An to release Qu Liuqiao.

But before they could kick open the door of 1901, Qu Liuwan walked out of it by himself, with a wry smile on his face.

"Team Xiang, the vigilance of those bodyguards is too high! They seem to regard me as a killer, and I can only take out the police officer~ card to prove my identity, so I can get out. Qu Liuwan explained with a bitter face.

"Go back first, and when Tang Tian comes back, we'll have a meeting to discuss. "Xiang Yu still knows a lot about Qu Liu's weak ability, and since it has happened, now is not the time to hold him accountable.

More than ten minutes later, Tang Tian pushed open the door of 1806 and saw Qu Liuqiao and Xiang Yu sitting at the table frowning.

"Team Xiang, don't take you to joke like this!" Tang Tian's heart that had been holding along the way relaxed, and his gaze at Xiang Yu was quite unkind.

"Are you kidding? Who is kidding you?" Xiang Yu also had a black face, he was a wounded man in a wheelchair, and he almost led the team to save people in person, why did it become a joke?

In the end, under Qu Liu's weak explanation, Tang Tiancai understood that in just twenty minutes, the situation on Lu An's side had actually undergone such a huge change.

"Then we can only give up covert monitoring now and contact Lu An directly!"

Tang Tian didn't have any other way, Lu An's vigilance made him wonder, although Lu An had two hens that laid eggs under his name, and they were still the kind that laid golden eggs, but that wouldn't be like this, right?

The only explanation is that Lu An is hiding from his return to China this time!

In other words, Lu An's return to China was not his intention, someone was forcing him to come back!

Obviously, Xiang Yu and Qu Liuqiao also realized this, which made them even more convinced that Lu An was the next target of the midnight murder bell serial murder case!

Waiting for Qu Liuqiao to change out of the hotel staff uniform he was wearing, Tang Tian pushed Xiang Yu, and the three of them knocked on the door of 1901.

"Why are you again!" The bodyguard who opened the door to check immediately recognized Qu Liuqiao, and his eyes couldn't help but be a little vigilant.

"We are policemen, you Mr. Lu are involved in a vicious serial murder case, we need to interview him!" Tang Tian immediately showed his police officer~ card.

The bodyguard wanted to stop him, but Lu An's voice came from the suite: "Let them in!"

Lu An's whole body was deep in the soft sofa, with a thick tired look on his face, and his temples were gray, making people feel that this was already an old man in his fifties and sixties, not a business tycoon in his early forties.

"Three comrades police officers, I don't know what the situation of the vicious serial murder case you are talking about? Do you suspect that I am the murderer?" Although Lu An looked a little old, his voice seemed very rich.

"No, we conclude that you are the next victim of this serial murder case!" Tang Tian didn't talk nonsense to him, he had read the information provided by Wang Wen, and he didn't have any good feelings for Lu An.

Lu An's face became solemn, he stood up slowly, and didn't speak, just looked out of the floor-to-ceiling window, frowning, not knowing what he was thinking.

"Chairman Lu, you are also one of the anonymous shareholders of the Anning Consortium, right? Do you know the other six people?" Tang Tian saw that Lu An's expression was different, and immediately stepped up his language offensive, "Whether you admit it or not, I must tell you a fact, including Wu Youqian, four of the seven anonymous shareholders of the Anning Consortium have died! And you are likely to be the fifth victim! So, here we are!"

"Chairman Lu, I think you may have received a threatening call at midnight, and you are very clear about what this call represents, for the safety of your own life, I hope you can cooperate with our police investigation!" Qu Liuwan then spoke, she hoped that Lu An could realize the current dangerous situation.

"I do hold shares in the Anning Foundation, but I didn't receive any midnight threatening phone calls, and I don't know what the phone call you said represents, let alone Wu Youqian!" Lu An's attitude was very uncooperative, and his slightly sickly face hung with anger, "I am a law-abiding citizen, without being notified, you actually want to install listening equipment in the suite where I live, I don't care about you anymore, what else do you want to do?" If you continue to pester, I will complain to your superiors against you!"

Lu An's non-cooperation surprised Xiang Yu very much, judging from the current situation, maybe Lu An really didn't receive a threatening call, but this is not in line with the style of the murderer in the midnight bell case!

"That's the end of today's conversation, Chairman Lu, you can reserve the right to accuse us, but we will not give up our investigation of you either!" Xiang Yu didn't wait for Qu Liuwan to push the wheelchair, and after saying this, he shook the wheelchair and walked towards the door.

Tang Tian and Qu Liuwan glanced at each other, both of them didn't understand why Xiang Yu gave up the inquiry so happily, and with strong doubts, the two of them still followed Xiang Yu quickly.

After returning to the suite, Tang Tian still couldn't hold back, and asked the doubts in his heart: "Team Xiang, why do you still say that you just left? There must be something wrong with that Lu An, his return to China is not voluntary, it is very likely that something outside or within the country forces him to return to China! These are the directions we can investigate!"

"You can see that I'm blind?" Xiang Yu didn't reply, his tone was full of depression, "Lu An is an old fox, he has been in the sea for half his life, he is completely different from Wu Youqian, our psychological offensive is useless to him!"

"What should I do then? It's just a stalemate?" Qu Liuwan was anxious.

"Wait! Now it's up to who can consume whom!" Xiang Yu took a deep breath, the current situation was urgent, either Lu An couldn't stand the torture of the threatening phone call and took the initiative to ask the police for protection, or he prayed that Jia Zuozhen's investigation of Anfeng Logistics Group could have a breakthrough!

It's just that, according to Xiang Yu's observation of Lu An, this person's temperament is by no means comparable to Wu Youqian and others, and he will definitely choose to use his own strength to protect himself instead of seeking police protection, just like the first three deceased.

"Although Lu An is not very cooperative, but we can't relax our monitoring of the 1901 suite, there is no way to monitor the situation in the suite, let's just keep an eye on Lu An's whereabouts, I don't believe that he can stay in the suite all the time!" Xiang Yu said this, and suddenly remembered Tang Tian's investigation of Liquan Water Purification Company, "Tang Tian, what are the results of your investigation of Liquan Water Purification Company?"

Xiang Yu didn't mention this, but as soon as he mentioned this, Tang Tian's face immediately changed, and he talked about his discovery in that warehouse with a depressed face.

"This is a picture taken by a remote-controlled plane, based on these, we can basically conclude that there is another cave under this warehouse, and it is very likely that it is the mushroom processing base we are looking for!" Tang Tian called up the video and put his mobile phone on the table, "But the phone call that the Xiang team made to me has already aroused the vigilance of the beard, and I suspect that they will cancel this stronghold in the shortest possible time!"

Xiang Yu nodded slightly, Tang Tian's worries were not unreasonable, but at the moment, there was really no extra manpower on the side of the Special Investigation Bureau to continue to follow up with Liquan Water Purification Company. After all, the two cases of mushroom soup and stealing corpses from the crematorium have been closed, and the most important thing at the moment is to follow up on the midnight murder bell serial murder case!

What's more, there is no clear evidence about Liquan Water Purification Company, everything is based on Tang Tian's speculation, Xiang Yuming knows that this speculation is very likely to be correct, but as a police officer, relying entirely on intuition and speculation to handle the case, there is definitely going to be a big problem!

"Let it go for the time being!" Xiang Yu had to make this decision, he continued to speak after a deep sigh, "But I can't completely leave it alone, I arranged for a few informants to disguise themselves as wanting to enter the warehouse to steal, or sneak in from the location of the kennel, so that maybe I can dispel the vigilance of that beard." ”

Tang Tian went through Xiang Yu's plan in his mind, and felt that there was no problem in general, the only thing to worry about was whether Xiang Yu's informant would be tortured to extract a confession if he fell into the hands of the beard?

"Are you worried that the informant will tell us about our plan?" Xiang Yu saw Tang Tian's concern, and a slight smile appeared on his gloomy face, "Don't worry! I've already thought about this! I'll let the patrol arrive in time, cut off the informant from the beard, and just find a detention center and lock him up for a few days!"

Seeing that Xiang Yu had already thought about all the details, Tang Tian could only agree to put down the line of Liquan Water Purification Company for the time being, although from his heart, he was eager to bring that beard to justice, but reason told him that Lu An might catch a bigger fish in this line.

After some discussion, Xiang Yu arranged the scope of work for the next step, Tang Tian and Qu Liuqiao were responsible for taking turns to monitor the 1901 suite, and Jia Zuozhen was still responsible for the unofficial investigation of Anfeng Logistics Group.

After arranging these, Xiang Yu closed his eyes and carefully went through all the details that he could think of in his mind, and he was now very sure that the joint deployment of the Special Investigation Bureau and the criminal police force under Wang Wen would definitely not be as passive as Wu Youqian's case.

In the next few days, Tang Tian and Qu Liuwan took turns to be on duty in the corridor on the 19th floor, like kraft candy, staring at Lu An inch by inch, how many hours he went out every day, where he went, how many people he talked to on the way, the identity information of these people, and even how many times Lu An went to the toilet during the outing, Tang Tian and the two of them were meticulously recorded.

On the other hand, as Xiang Yu expected, the municipal bureau, taking into account the sensitivity of Lu An's identity, did not approve the co-investigation order applied by the criminal police team, but ordered the criminal police team to pay attention to the scope of influence and not allow a negative impact on the Anfeng group until substantive criminal evidence was found.

This order made Wang Wen very annoyed, he felt that this was simply trying to let the horse run, and not give the horse grass!

Compared with the criminal police team, the life of the Special Investigation Bureau is much better, after all, the word "special" is destined to Xiang Yu to a certain extent, not to be constrained by cumbersome rules, and it is precisely because of this that Tang Tianqu and the weak two were able to stick to Lu An's side like kraft candy, if this was replaced by the criminal police team, he would have been scolded by his superiors on the phone.
