After dinner, Du Qiu and a few others finalized the plan and did not stay in the company.
He went to Ovi Sensing, a company that produces various types of sensors, and Du Qiu wanted to purchase a batch of customized sensors.
When the "Tianqing System" designed by Du Qiu is integrated with hardware, in order to achieve the best state, the hardware part needs to be modified and adapted accordingly.
Du Qiu has used this company's sensors a lot in his previous projects, and the quality is nothing to say. The key is that they accept customers' small-batch customization needs.
Du Qiu can also be regarded as their old customer, but this time Du Qiu's order is much larger than before.
The treatment of big customers is naturally different. The customization needs are quickly determined. After the contract is formed, Du Qiu pays the deposit and the work starts.
With their production speed, they can deliver the goods in three days.
After finalizing the matter, Du Qiu declined the dinner invitation from the CEO of Ogilvy & Mather Sensing.
It was only 4:30 in the afternoon. Du Qiu couldn't wait for an hour or two for dinner.
What's more, he also wanted to go find Qin Yun and give her the alarm watch.
Ogilvy Sensing Company is about a fifteen-minute drive from the shipyard where Qin Yun is working, which is not very far.
Du Qiu drove the car, with his own modified navigation map displayed on his mobile phone.
"Didi, there is congestion on the planned route. Do you want to take alternative route one?" The phone suddenly sounded a notification tone.
Du Qiu glanced at it and immediately pressed OK on the phone screen, and the car then followed the new route.
Within a few minutes, the car was guided to a branch road. There were very few vehicles on this road. It should be a detour to the side of the shipyard.
The car hadn't been driving for long when Du Qiu's cell phone suddenly made a beeping sound, abnormal signal transmission detected!
"Well, what's going on? Someone is following me?"
Du Qiu muttered in surprise, but did not stop the car to check. He looked carefully in the rearview mirror.
There were no vehicles following him on the deserted road.
Du Qiu slowed down the car and quickly scanned his surroundings with his eyes.
On the left side of this road is the tall wall of the shipyard, and on the right side are some buildings of different styles. There seem to be factory-like buildings and a few old-fashioned residential buildings with five or six floors mixed in. They all seem to be from the 1970s.
Architecture of the 1980s.
The car continued forward, and there was a building near the intersection, which was a hotel.
When Du Qiu was about to turn left, he suddenly saw a woman getting out of a van in front of the hotel, and he was a little surprised.
He pulled over the car, then picked up his cell phone and dialed the number.
"Officer Ning, are you busy?"
The woman Du Qiu saw was Ning Shuangshuang. She was not wearing a police uniform today. She was wearing a light gray long-sleeved shirt and a pair of black straight pants. She looked like a female college student.
After she got off the car, she was about to walk to the hotel door. After answering Du Qiu's call, she walked aside.
"You have something to do with me?"
"Are you on vacation or at work?"
Ning Shuangshuang suddenly raised his head and looked around, "Did you see me?"
Du Qiu didn't expect that Ning Shuangshuang's reaction was so sharp. He could guess that he had seen her with just one sentence.
"How smart! Did you see the third car parked on the roadside in front of you? I'm in the car."
After Du Qiu finished speaking, she saw Ning Shuangshuang looking towards her. Then she hung up the phone and walked to the van where she got off earlier. She seemed to say something into the car.
Then, Ning Shuangshuang walked towards Du Qiu.
After getting in the car, Ning stared at Du Qiu with both eyes.
"Hey, Officer Ning, I'll be embarrassed if you stare at me like this."
"Did you appear here by chance again?"
"Yes, I came to the shipyard to find Qin Yun and give her an alarm. Who made your protective measures withdrawn?"
Ning Shuangshuang looked back and asked, "What alarm?"
"I made it myself. It's in the shape of a watch. Whenever Qin Yun and the others are in danger, they can press the button to call the police and display their location."
"Aren't you studying driverless cars? How can you do such a thing?"
"Officer Ning, I just worked in a driverless technology company before. I have a PhD in mechanical electronics and am very familiar with electronic products."
Du Qiu said, but still asked curiously, "You must be working, right? I didn't disturb you, right?"
"I am working, but asking why you are here is also within the scope of work." Ning Shuangshuang looked at Du Qiu and asked, "Tell me, how did you take this path?"
"I came from the west, and the original road was blocked by traffic. After re-navigation, I went around here."
Du Qiu suddenly realized something and asked cautiously, "Are you protecting the shipyard? No wonder you are protecting Qin Yun, she is from the shipyard."
Ning Shuangshuang's eyes flashed with admiration, but he said, "Don't ask what you shouldn't ask. If you want to deliver something, just hurry up. Qin Yun will get off work soon."
With that said, Ning Shuangshuang was about to get out of the car, but suddenly she stopped and turned around and asked, "Are you familiar with electronic products?"
"yes."
"Is there any way that can allow people to hear the sound of the target room from a distance of more than 800 meters without installing a bug?"
Du Qiu thought for a while and said, "There are many ways. You can use bionic electronic flies to fly to the window of the target room.
You can also use a bullet bug to eavesdrop by firing the bug into the wall of the target room through a gun."
Ning Shuangshuang shook her head and said slowly, "There should be none of these. We can ensure that there are no such electronic items in the target room.
In fact, it is impossible for unknown electronic items to approach the target room within a radius of several hundred meters."
"There is another method that does not require electronic items to approach the target. It only needs to illuminate the glass window of the target room with a laser, and it can monitor the conversations of people in the target room."
"What?" Ning Shuangshuang was shocked and asked, "How to detect this method?"
"Can detect whether there are abnormal signal transmissions in the surrounding area..."
When Du Qiu just said this, he suddenly remembered that when the car came over just now, the warning network system in his car detected abnormal information transmission.
"What did you think of?" Ning Shuangshuang saw the change in Du Qiu's face and asked speculatively.
"Officer Ning, my car is equipped with a detection system. When I just came over, it seemed that an abnormal information transmission was detected."
"Where is it? Take me there quickly!"
Du Qiu quickly started the car, turned around at the intersection, and drove back slowly.
When passing those old residential buildings, Du Qiu's cell phone issued an alarm again.
"Beep beep, abnormal signal transmission detected!"
Ning Shuangshuang looked at Du Qiu's mobile phone and asked, "Can it be accurately positioned?"
Du Qiu picked up the phone and clicked on the A interface. A three-dimensional space map with Du Qiu's car as the center and 200 meters around was immediately displayed on the phone screen.
A red dot is displayed at the location of a house next to the road, with a height value displayed next to it. After simple conversion, it can be determined that it is the top six floors of this house.
"It's on the sixth floor of the building along the road. It should be the room on the north side."
"Sit here and don't move!"
Ning Shuangshuang opened the door and got out of the car, turned on the communication headset on her collar, and issued a series of commands.
Then, she walked towards the residential building first.
When Du Qiu saw it, he thought, isn't it? He is so fierce, and he didn't even wait for his companions to arrive.
Just as he was about to get out of the car to help, he saw Ning Shuangshuang suddenly turned back and waved at him.
