No. 1 knocked on the door of a house on the corner of the third floor, and they saw from the surveillance video just now that the man stopped here and seemed to talk to the family for a while, and then he disappeared again.

In the fire escape and elevator, there is no one to be found. That would only mean that the person had entered a certain room.

The door opened, and it was a young girl in her twenties, who saw No. 1 and frowned with obvious impatience, "Who are you?" Something? ”

Most of today's girls are judged by their appearance, although No. 1 is not ugly, but unlike those boys that young girls like nowadays, the square face is always serious and unpleasant.

Ignoring the girl's impatient tone, Number One asked, "Excuse me, did you bring back a guest just now?" ”

The girl looked up at him and squinted, "What do you mean?" Also, who are you? ”

No. 1 said, "I'm sorry, I'm from the property, and I just saw a resident of the building who wasn't ours entering your house, so I'm here to ask." ”

Hearing this, the girl suddenly thought of the bad aspects, her face was ugly, and she pushed No. 1 away, "What do you mean?" What guests did I bring back? I can tell you, I'm the only one in my house, don't say such things casually, or I'll sue you!" ”

No sooner had the No. 1 who had been pushed to the door slammed shut.

"Boss—"

No. 1 looked at Zhao Xi, who had been standing by the elevator and watching this scene, without snorting a word. Doing their job, with his eyesight, of course, he saw the disgusting eyes of the young girl, if the head of his family took two steps to this side, if the girl saw the leader's face, he would definitely not be in this tone, and he would definitely be able to provide two more clues.

The corners of Zhao Xi's mouth twitched, and he said to the headphones with an expressionless face, "All, please pay attention, spread out, and conduct door-to-door inspections on each floor, starting from the fourth floor!" ”

In a certain house on the fourth floor, there are several large boxes neatly packed and waiting for the courier to come and send them, and the owner of the room is standing in front of the window, looking at the opposite side through the binoculars.

Opposite, is the research building of a scientific research institution.

Ye Chi munched on potato chips and stared at the surveillance video, but his eyes drifted away.

If she is Chi Qing, what should she be doing at this time?

If Chi Qing is also a spy, then he must not simply live here, he must have a certain purpose.

She asked the security captain standing nearby, "What's around this building?" ”

The security captain thought for a moment before replying, "Oh, there's a large supermarket not far from here, and there's a scientific research building across the street from this building......"

Research building?

Hearing this, Ye Chi's heart moved, and she couldn't listen to the words of the security captain anymore.

Ye Chi's voice came from Zhao Xi's headphones, "Zhao Xi, there is a scientific research building opposite this building, and that person must live in a place where he can see the building." ”

Zhao Xi looked at the map in his hand, his fingers swiped somewhere, and quickly said on the walkie-talkie, "All please note, now you only need to check the three rooms of 02, 03, and 04 on each floor!" ”

Only the windows of these three rooms are facing the opposite research building, while the windows and doors of the other two rooms do not see the opposite research building.

In room 404 on the fourth floor, the person who was looking at the opposite building through the telescope was frowning as he swept the car parked downstairs, when the doorbell rang, and it was the courier he called.

Through the cat's eye on the door, it was determined that it was indeed the courier outside the door, Chi Qing opened the door, his eyes swept left and right flexibly, and quickly closed the door after finding that there was no one.

Number one and number two are ringing the doorbell of 402.

Zhao Xi stood at the top of the stairs, his eyes roaming left and right, and his right index finger lightly tapped the handrail of the stairs.

The door of 404 opened, and out came a young man wearing blue overalls and a wide-brimmed hat with the words "Daily Express" printed on his clothes.

Zhao Xi's eyes swept over him, then turned his gaze, and when the courier pressed the elevator, he turned his head sharply.

Wrong! That's Chi Qing!

said that it was too late, and at the moment when the elevator door opened and Chi Qing had already stepped into the elevator with one foot, Zhao Xifei ran over and squeezed into the elevator, and the elevator door closed with a "ding".

And Ye Chi, who was staring at the surveillance video in the security room downstairs, also stood up.

The building, although it has two elevators, is in the same place. Ye Chi threw down the potato chips and ran straight to the elevator. Either way, she had to stay at the elevator door.

She wants to find out, is this Chi Qing the same Uncle Chi who started a business with her father back then?

The security captain was stunned for a moment, and only woke up when Ye Chi ran out of the door of the security room and followed.

The elevator fell slowly, the door opened with a "ding", there was no one inside, Ye Chi's eyes were staring at the other elevator, for some reason, she always felt that there was no one in this elevator.

Seeing the two security captains standing behind him, Ye Chi pursed his lips and said to them, "You guys are staring here, no matter who comes out of the elevator, be sure to leave people behind." ”

After struggling slightly, Ye Chi leaned towards his instincts.

She, on the other hand, ran quickly to the fire staircase.

The elevator comes down from the fourth floor, and it only passes through the third and second floors.

At this time, behind the fire door on the third floor, Zhao Xi was engaged in a silent battle with Chi Qing.

Compared with Chi Qing's flexible and changeable figure, Zhao Xi's big opening and closing could not take advantage of this narrow space, and he almost let Chi Qing evade him and slip downstairs a few times.

When Ye Chi jumped up with the handrail of the stairs, he saw Chi Qing shaking his body, getting out from under Zhao Xi's ribs and jumping downstairs again.

The hat on Chi Qing's head had already fallen off, and a face completely appeared in Ye Chi's eyes.

The person in front of her looked exactly like Chi Qing, but his whole expression was not at all similar to what Ye Chi had seen before, and the appearance of Chi Qing who remained in her mind.

Calm, fierce.

Maybe this is Chi Qing's true face.

Ye Chi smiled, and when he saw Chi Qing who jumped to his side, he didn't hesitate to stretch out a leg.

Chi Qing, who was tightly bound by his own belt, couldn't see a little panic on his face, and when he looked at Shang Yechi, his eyes were very calm, and he couldn't see any ups and downs.

Ye Chi kicked Chi Qing, who was half-sitting on the ground, and asked Zhao Xi, "Why do I look at him and think he doesn't look like Chi Qing, could it be plastic surgery?" Aren't you a doctor? See! ”

Zhao Xi really squatted down, pulled the skin on Chi Qing's face, and looked at it carefully.

Chi Qing's face was annoyed, a big man was questioned about plastic surgery, which was a very humiliating thing.

This annoyance, which originally looked quite pleasing to the eye, revealed a different ferocity.

Ye Chi also squatted down and stared at Chi Qing's eyes tightly, "Uncle Chi, this is your true face, right?" ”
