Song Sen asked his men to free up more than ten empty rooms, one on each floor, and the distribution was randomly selected.
“The men and women of the detainees will be mixed up and brought in. If the gender is targeted, the murderer may be alerted.
Lingyou, think again, what else needs to be prepared in advance.
If according to your analysis, Huang Huanxin will make a very important move in the next step.
I'm afraid our hasty preparations are not enough to shake his plan.
I have deployed personnel at the entrances and exits of each floor. Once the murderer is exposed or takes Huang Huanxin hostage and escapes, we can quickly gather the dispersed personnel to one point."

Song Sen's brain was running rapidly, fearing that there would be any mistakes or omissions if he didn't think carefully about any link.
He stared at Lu Lingyou motionless.
"Speak."

Lu Lingyou curled his lips and flicked the ashes from his cigarette.
"If we want to expose the problem between Huang Huanxin and the murderer, we must allow them to successfully complete the connection.
If according to your arrangement, all entrances and exits of the hotel are kept airtight, how can you let them be exposed?
Discussing secret deals before our eyes and then breaking up?
Of course Huang Huanxin hoped that the police would take action to eliminate this biggest threat to him as soon as he saw the murderer.
But the murderer is not stupid. I don’t believe she waited calmly in the hotel for so long without leaving any options for herself."

Song Sen frowned, put a cigarette in his mouth, and lit it.
"I understand what you mean, but we must have a complete grasp of the status and conversation between Huang Huanxin and the murderer.
Any mistake or omission in one second may bring completely different reversal and omissions to the result.
And once the murderer discovers that Huang Huanxin is playing tricks, he will definitely kill him as soon as possible.
If Huang Huanxin dies, then this game may really go as they wish, and two dead people will have to take all the blame."

Lu Lingyou crushed the cigarette butt twice in the ashtray.
“So, we must take strict precautions while leaving a relatively “safe” space for them.
But this so-called safe space is only from their perspective."

Song Sen stared into Lu Lingyou's eyes and thought for a moment.
"You mean to leave them a chance to survive while under tight control."

"Yes."

Lu Lingyou nodded and unfolded the hotel layout map on the desktop.
"Manpower must still be arranged at each entrance and exit to ensure that not even a fly can fly out.
But here.”

He pointed to the location of the exterior wall on the southwest side of the hotel.
"Extended staircase on the hotel facade.
Every third floor there is a fire door connected to the interior corridor."

Song Sen hummed.
"really.
But there are a few issues how are you going to deal with them.
First, we have checked the doors leading to the outdoor passages and they are all locked.
At present, apart from the known information about the woman, we do not know the clear direction of the murderer.
If we take the initiative to open the locks on certain floors in advance, will it be too obvious?
And the more we open, the more uncontrollable it becomes. Once there is an emergency, it will be difficult for us to go back and block the channel as soon as possible.
This would be counterproductive.
Second, there are indeed peripheral monitors that can be taken care of, but they can only capture images, but not sounds.
Once the murderer realizes this, it is still very easy to smash a few surveillance cameras.
Third, when they take this path, they have only two choices: upper and lower.
On the premise that we guard every exit on other floors, we can either force them into the underground garage or lead them to the rooftop.
But both places have their pros and cons.
The underground garage is cramped and has many blind spots. Once the murderer takes Huang Huanxin hostage, it will be difficult for a sniper to pose a threat to him from a certain angle, and it will be even more difficult for us to arrest him.
The rooftop is more convenient, but the convenience of the rooftop will also give the murderer more opportunities to escape."

Lu Lingyou took out his cigarette case, poured a few cigarettes out on the hotel layout, and placed them at several points.
"If I had to choose, I would choose the rooftop.
The fire exits in the corridors on every third floor must not only be opened but also locked.
Not only can it reduce the murderer's defensiveness towards such a road, but it can also restrict the murderer.
She could only open the door from the inside. After being led to the outdoor stairs, she could no longer enter the room.
In this way, they have no choice between going up and down and can only go to the rooftop."

Song Sen frowned and thought.
"How can you be sure that the murderer will be able to open two locks in a short time?"

Lu Lingyou snorted lightly.
"You can do it, and so can I.
I believe that the person doing the final finishing task can do it too.
If she can't even do this, then it would seem like we are too much of a loser because we were fooled around."

Song Sen sighed.
"Go on."

"The peripheral monitoring you mentioned is one way, but we cannot completely rely on these monitoring points.
We also need to do something with Huang Huanxin along the way."

"You mean to temporarily install hidden surveillance cameras at the points you marked.
Then add positioning monitoring equipment to Huang Huanxin's body armor.
But Huang Huanxin is not stupid. If he wants to do something, he can just take it off."

Lu Lingyou shook his head.
"In addition to the one in the body armor, there is another one in a place he didn't expect.
As for where to add it, it's up to you.
And I guess he won't take it off.
Even if he knew there was something in his body armor, he would not take it off.
He wanted to win so much, but he was also afraid of death.
The police are his last resort weapon and a tool to save his life.
So how could he completely escape the police's radar?"

After a long while, Song Sen finally nodded.
"Okay, leave it to me to arrange it." While several people were waiting for the arrangement in the room, Lao Fang sent another wave of support and brought some protective equipment along the way.
Lu Lingyou picked up a body armor and handed it to Fang Ning.
"Put it on and follow me soon and don't run around."

Fang Ning took it and didn't know how to put it on for a while. He stared at Zhao Yue who was also putting on the equipment not far away, and followed the same pattern.
Before she could learn it all, she suddenly felt the vest on her hand loosen, and Lu Lingyou pulled back the body armor again.
He turned around and pulled it over Fang Ning's head, then lowered his head and patiently tied the buttons around her waist.
Song Sen just put down the phone and turned to look at the two of them with a frown.
"Does Fang Ning have to go? It's too dangerous.
If there is any emergency, you and I may not be able to take care of it."

Fang Ning obediently raised her arms to match Lu Lingyou's movements, and smiled at Song Sen.
"I don't lean forward.
And when Huang Huanxin identified the murderer, every reaction was important.
This may be our key to opening the last door.
If you look behind a monitor, you may miss a lot of important information.
Don’t worry, I won’t act privately.”

Lu Lingyou pulled the side of the waistcoat and turned her around half a circle to face her back, and then pinned the battery of the communication device to her waist belt.
"Put on your headphones and let Zhao Yue change the channel for you."

Feeling the strong presence of warmth behind her, Fang Ning felt slightly uncomfortable and wanted to find some topic to distract her attention.
"By the way, what did you mean when you asked Song Sen to install an additional monitoring device on Huang Huanxin?
And only Song Sen can do this?"

Lu Lingyou lowered his head slightly and whispered to Fang Ning.
"Don't look at the people Song Sen cleans up all day long. They all look upright, but there are quite a lot of crooked people.
When he was in school, he was almost selected to work as an undercover agent in the border area."

Fang Ning turned around in surprise.
"real or fake."

Lu Lingyou glanced at Song Sen, who had a solemn expression, and nodded with a smile.
"That's not the case.
And when he was in school, he had a record that no one could break."

"What record?"

Lu Lingyou's chin almost touched Fang Ning's shoulder and she didn't notice anything was wrong.
"Steal the archives key from the instructor.
There are many archives of old confidential cases that are not open to the public in teaching, and we secretly sneaked into the archives in the middle of the night to read them."

Although the two people were having a conversation, their eyes were all looking towards Song Sen at the same time.
Song Sen rolled his eyes in frustration.
"That's enough for you two."

After a few minutes, everyone was cleared up, and Huang Huanxin was taken out of the room by Song Sen and his men.
According to Lu Lingyou's prior instructions, Huang Huanxin was not handcuffed in order to prevent the murderer from stressing out.
As soon as he left the room, Huang Huanxin began to look around and at the police arrangements in the corridor. After looking around, he turned his head and looked back to Lu Lingyou.
Lu Lingyou raised his eyebrows expressionlessly.
"Why, I feel like we don't have enough manpower."

Huang Huanxin forced out a professional smile.
"How is that possible? I believe in the capabilities of the Army."

Song Sen pushed Huang Huanxin's shoulder.
"Let's go then.
Remember what I told you, don’t make any unnecessary movements for a while, just look and say.
Don’t identify him face to face. When I ask, you can say whether you have it or not.”

"it is good."
