The building is an old building, only six stories high, and there is not even an elevator.

Xue Xing walked into the corridor and heard footsteps from above.

He followed him up to the third floor when he heard footsteps stop, followed by the sound of the door opening.

When he heard the sound of the door closing, Xue Xing quietly walked up.

There are only two families on one floor.

Judging from the voice just now, Li Li entered the room on the left.

Xue Xing listened to it close to his ear, and there was movement in the room, but he couldn't hear it clearly.

Ding Yuan was not inside, he was not sure.

There was no way, Xue Xing had no choice but to go downstairs and stand under a tree not far away and wait.

After waiting for more than ten minutes, Xue Xing saw a black sedan drive over and then stopped downstairs.

A pot-bellied man got out of the car.

Xue Xing looked at it, damn, it was really Ding Yuan!

Ding Yuan looked around for a while, and then walked into the building.

Xue Xing sighed that his luck was really good, and on the first day of surveillance, the two went on a date.

Although he couldn't get anything, their nest was exposed, and things were easier to do after that.

Half an hour later, Li Li walked out of the corridor first.

There was an indescribable satisfaction on her face.

This kind of expression Xue Xing could often see from Wang Xu'er's face before.

She walked easily to her car, then walked away.

After five or six minutes, Ding Yuan also came out.

However, his expression was not the kind of relief after the relief, but the brow was tightly locked, as if he was thinking about something.

It's a pity that Xue Xing didn't shoot anything.

It's useless to just film them going in and out of the hallway.

There must be a stone hammer.

Xue Xing thought about it and decided to enter the house and install a pinhole camera!

But this is not an easy job, first, it is difficult to enter the house, and second, he has no equipment or anything like that.

After pondering for a long time, Xue Xing thought of someone.

He might have been able to help himself.

So, Xue Xing took out his mobile phone and dialed his number.

"Hello?"

A low, magnetic voice rang out.

"Master Zhang, hello! I'm Xue Xing, Gao Xueran should have mentioned me to you, right?"

"Oh, hello, Xue Ran mentioned you, we've met before. ”

"Hehe, that's the case, I'm helping Gao Xueran with errands now, I need your help, are you free?" He said bluntly.

Before, Gao Xueran also said that you can find him if you have something.

Judging from his previous deeds, Xue Xing knew that Master Zhang was a trustworthy person.

"Half an hour later, you come to my computer store, and we meet and talk. "He's also simply.

"Okay, that's all. ”

Picking up his phone, he walked to the motorcycle.

Half an hour later, Xue Xing came to the computer repair shop.

Zhang Zongyi was already sitting in the store waiting for him.

He was in a much better mood than he was in the hospital.

It should be that the fact that his wife died has been accepted.

But as Gao Xueran said, his heart may have followed his wife, and he will never be able to talk about his relationship again.

"Master Zhang, fate!" Xue Xing smiled.

"Fate. He smiled back.

"Master Zhang, time is tight, so I'll just say it directly. ”

"Okay, you say, what do you want me to do?"

Xue Xing sat down and told Gao Xueran and Chen Zhen about the competition for the second phase of the Longbao Economic Development Zone, of course, the grudge between himself and Chen Zhen was hidden.

As for Gao Xueran's side, Xue Xing believes that she should not have said anything about her wife's cheating.

Gao Xueran is a quality person, and without his consent, she will not tell others, including Zhang Zongyi, about things that damage his dignity.

She had promised it a long time ago.

Xue Xing then introduced: "Today I followed Li Li and found the place where she and Ding Yuan had a tryst, in an old residential building. ”

"The problem now is that to get evidence of their date, we have to go into that house and install pinhole cameras. ”

"I already have an idea of how to get into the house, and as for installing a pinhole camera, I need your help. ”

"I happen to have a pinhole camera here. Zhang Zongyi said, "You can not only take images, but also record and control them with your mobile phone, which is very convenient." ”

"That's great. Xue Xing said happily, "Now it's easy." ”

Zhang Zongyi asked: "Then how can we get in, we can't just pry open the door, right?"

"It's easy. Xue Xing has a heart.

"Simple?" Zhang Zongyi was stunned for a moment, "Do you know how to pick the lock?"

"I won't pick locks. Xue Xing said, "There's no need to pick the lock, if the lock is picked, they find out, and we can't monitor it." ”

"Then how can you get in without picking the lock? Even if it's the first floor, there should be an anti-theft net, and you can't get in through the window, right?"

"We'll go now, and you'll know when you go. Xue Xing smiled mysteriously.

"Alright!"

So, Zhang Zongyi took a toolbox, got on his motorcycle and set off.

Halfway through, Zhang Zongyi was still a little confused, but when he saw Xue Xing's confident face, he didn't ask too much, anyway, he knew right away.

Thirty minutes later, the two of them came to the neighborhood together.

"That's the building. Xue Xing said.

Then, he instructed: "In this case, let's go to the nearby vegetable market or supermarket to buy some vegetables or daily necessities." ”

"What?" He was a little surprised.

"Let's go, you'll know in a moment. Xue Xing's tone was mysterious.

Half an hour later, the two men returned with two large pockets.

"Alright, bring your tools, now let's go upstairs!" Xue Xing commanded.

Zhang Zongyi's tool for installing a pinhole camera is not large, so he put it directly in his pocket and brought it with him.

The two of them came to the fourth floor together.

"This is it. Xue Xing said, "Look at it." ”

Zhang Zongyi carried his things and was silent, just looking at Xue Xing to see what he had to do before he could enter the room.

Xue Xing was also carrying a large bag of things in his hand, and he knocked on the door next door with a natural expression.

The door opened a little halfway, and a middle-aged woman in her forties poked her head out.

"Hello, eldest sister. We are staying across from you and forgot to bring the keys when we went out just now. I want to ask, do you have a phone number from the locksmith?"

Xue Xing's face was amiable.

Seeing Xue Xing say this, Zhang Zongyi was also smiling on the side.

The eldest sister looked at them for a while, and then said, "There is a small advertisement on the wall!"

"Oh, oh, thanks, we didn't pay attention. Xue Xing smiled.

The eldest sister closed the door.

Xue Xing handed the things to Zhang Zongyi, took out his mobile phone, walked to the wall, looked at the small advertisement on which the lock was unlocked, and made a call.

After making the call, Zhang Zongyi asked in a low voice: "Okay, can you do this? If you do this, people will unlock you? You can't prove that we are the owners of the house here." ”

He didn't understand Xue Xing's operation at all, and he could naturally find a locksmith to open the door, but that required something to prove his identity.

In fact, every locksmith is on file with the police station, and if something happens, they are also responsible.
