"Huang Que, do me another favor, I need the last half an hour of surveillance of the entire building, help me find a killer disguised as a delivery man in a certain group, this is very important to me, please."

Lang Xiao's tone was unprecedentedly solemn.

Only Lang Xiao can make Huang Que take a break from his busy work to help him.

Huang Que rarely saw Lang Xiao so serious and depressed.

She seemed to realize something, and didn't ask, just replied briefly: "Okay, I've turned on synchronous transfer, you activate the software on your phone, and you can watch the screen I searched for synchronously." ”

Lang Xiao took a deep breath and said gratefully, "Thank you, Huang Que." ”

"You don't always like to say thank you, but today in just half an hour, you said it twice, I don't want to hear the third time, we are good brothers, no need."

Huang Que said lightly, waving his hands, and there was a crackling sound.

She took over the surveillance of the building in an instant.

Countless images began to flash at the same time, searching.

Within half an hour, at least a dozen couriers walked into the building.

That's the good thing about modern society, the ubiquitous cameras that make people have nowhere to hide.

Through comparison and selection, there are three people who are very suspicious.

Looking at these three people, Lang Xiao was also confused.

He only glanced at it in a hurry, but he didn't see the man's face.

It's hard to tell the enemy by their size and outfit alone.

His heart moved, the killer and the takeaway girl had been photographed at that time, and he should have seen his face clearly.

Not good!

Lang Xiao's heart jumped.

Takeaway girls aren't in danger, right?

With the help of Huang Que, Lang Xiao is equivalent to having the eye of the sky.

Anyone who wants to leave this neighborhood will leave a trace.

Lang Xiao walked back to the elevator, seemingly playing with his mobile phone, a typical person who bowed his head.

On the screen of his mobile phone, there are nine small squares all over the place.

Each small square is a surveillance camera.

Lang Xiao looked at the upper ninth floor.

Almost all of the people who appeared at this moment were women and children.

There are no suspects of similar size, but there is none.

Lang Xiao is calm on the surface, but she is extremely angry inside.

Anger is an emotion he hasn't had for a long time.

No matter what the situation is, he can keep himself calm and face it calmly.

But today, he obviously can't do it.

"Boss, I found it, the killer got out of the elevator on the 16th floor, and he entered room 1602."

Huang Que said suddenly.

Lang Xiao's hand immediately pressed on the button of 16.

"Don't worry, I've locked him down, even if it's heaven and earth, he can't escape."

Huang Que comforted.

"Okay, next time we meet, I'll invite you for a drink."

"Invite me for a drink? Are you sure? ”

Huang Que was shocked.

Don't look at her as logistics, but she is fiercer than the average man.

Especially drinking, it can be called a bully.

Anyway, Lang Xiao has never seen such a woman who can drink.

And she has a very high IQ, once she gets drunk, it is estimated that she will even take out the bed a few times when you were a child.

Lang Xiao has never dared to fight with her, because she is afraid that she will dig up her roots.

And Huang Que seems to be very interested in his past.

This price is a bit big.

"Boss, you have to hurry, the killer has successfully disguised himself a minute ago, and he has gone up to the 18th floor again."

Lang Xiao looked at the young man who had changed into a picture with an astonishing killing intent in his eyes.

Although the young killer's actions are secretive, there are almost no flaws.

But with the help of the yellow finch, there is nothing to hide.

At this moment, he has a straight suit, bright leather shoes, and a successful person in society.

Especially the elite temperament on his body, it is absolutely impossible for people to associate him with the killer.

Lang Xiao canceled the 16th floor, and her heart was a little anxious.

If you put the delivery girl in danger because of your own negligence, it really shouldn't be.

"Something wasn't right, he didn't get off the elevator on the 18th floor."

Huang Que's voice revealed a hint of surprise: "This shouldn't be! The elevator stopped and didn't move, did he know you were chasing him? ”

Lang Xiao sneered: "No matter what he plans, don't want to live." ”

"Head, the police are already here, you have to hurry."

As soon as the sound of the yellow finch fell, the siren chirped and approached.

Lang Xiao stood up, came to the elevator next door, and pressed the door button.

At this moment, he seemed to be calm, but in fact, his muscles were already tense, and his whole body was like a spring ready to start, ready to burst out with great power at any time.

The elevator door opened, but Lang Xiao's attack was delayed.

He was shocked and said, "How is it possible? No one in the elevator? ”

Yellow Sparrow couldn't believe it.

Could this killer be a god?

After the killing, he slipped to the 16th floor, changed his clothes and then entered the elevator, but disappeared.

Is it an elevator or a portal?

Lang Xiao's eyes froze, and he said in a deep voice: "Help me continue to monitor all the directions of this building." ”

"No problem, this kid has really caught my sister's attention, I have to find out his bottom, you wait for me."

Such a small task, Huang Que didn't pay attention to it at all.

She's busy with a big case at hand.

At this moment, she really shifted her energy.

With the physical characteristics of the killer, it is too simple to find out where it came from.

Lang Xiao was a vertical body, and lifted the top with one punch.

Sure enough, this top was tampered with, and he easily unlocked the ceiling and got into it.

When she got to the top, Lang Xiao knew that she had come to the right place.

There was a set of freshly changed clothes on top.

"Yellow Sparrow, the killer got on the top of the elevator and changed his costume again."

"Head, find out the information of the killer, his name is Variety Fox, he is a three-star mercenary in the underground world, he is good at disguise, he is cautious, and he does things without leakage, so far, he has received no mission, not a single failure, this is a new fierce general."

Lang Xiao's face sank: "Could it be that he took over the task of the Mercenary Guild?" ”

"Yes, three days ago, someone offered a reward for Song Qingshan."

"What are the strengths and abilities of this person?"

"In addition to camouflage, it is a means of assassination, he is good at hidden weapons, especially hiding in the dark to hunt, head, you be careful."

Lang Xiao's heart sank, and said, "Even if he is a mouse, I will pull him out." ”

"Hehe, that's not necessarily."

Suddenly, a chuckle came.

Sou!

The cold light flashed, and the ice was biting.

Lang Xiao was startled, and felt a black shadow coming straight towards him.

The sixth sense he had developed for a long time saved him.

At the moment when she felt bad, Lang Xiao's whole body fell.

This is the eighteenth floor, and the elevator shaft below is miserable, and it makes people dizzy at a glance.

Sou!

A cold light flew almost against Langxiao's cheek, and when it hit the wall, a spark appeared in the dimness.

If it weren't for Lang Xiao's quick decision, I'm afraid he would have cut his throat.

Touch!

Lang Xiao did not fall down the elevator shaft on the eighteenth floor.

At the last moment, the instep of his foot firmly hooked the edge of the elevator.

It all happened between the lights and the fire.

The black shadow also sighed in surprise, but without the slightest hesitation, he stepped down heavily.

Lang Xiao's eyes were like lightning, shining with essence.

As soon as he lifted his breath, the whole person shook and leaped up, like a bird, grabbed the edge of another elevator, turned over and stood up.

Rumble!

The force of this foot is very heavy, I am afraid that there are hundreds of catties, and the entire elevator is trembling.
