In the summer, Lilian must turn on the air conditioner and turn off the window when going out, so that the diffusion of odor molecules will be isolated.

The reason why it is quite obvious around the villa is that when she got home, she got off the car and the odor molecules on her body had room for evaporation.

It seems that it is difficult to find her destination directly with one odor molecule alone.

"Lilian, are you going out in the afternoon?"

"No, what's wrong?"

"Open the mini for me, my air conditioner is broken."

That's right, Gao Ang made his mind to the mini                                                        �

Lilian drove out in the morning, with the windows closed, and there was only one place that could emit a violent smell along the way: the mini's exhaust pipe.

I got the key, got in the car and fired. A man and a cat squatted in the exhaust pipe at the rear of the car, breathing in the exhaust gas.

As soon as she smelled it, Xiaohua couldn't help but sneeze, slapped Gao's hand away, and rushed into the mini car with disgust.

"You guys, how good it smells."

I don’t have to worry about embarrassing myself when I said it. Gao Ang liked to smell this smell when he was a child. At that time, there were generally no cars, but there were motorcycles and tractors.

If you have something to do, follow the tractor's butt. Occasionally, you will have such a big mouthful, and your nose is filled with the fragrant smell, making you feel much more comfortable.

It was not until he went to junior high school that he realized how stupid this behavior was.

There are too many toxic gases in the fuel exhaust, and even those aromatic hydrocarbons and aldehydes that make him addicted to it are no less harmful to the body of ordinary people than nicotine, and it is even worse.

So from then on, he stopped chasing the tractor and hid in the toilet and started breathing the fragrance of nicotine.

After taking a few large breaths of exhaust gas, the odor molecular data of mini exhaust gas was imported into the database, and a person and a cat began the tracking journey.

Although the weather became gloomy, fortunately, there was not much wind blowing, and the odor molecules were still floating on Lilian's way back and forth, and did not cause too much trouble for a person and a cat.

"How could it be here?"

Looking at the gilded characters "Changsheng Bio", Gao Ann realized why he was so familiar with the smell on Lilian.

This smell is the smell of the pharmaceutical factory near Vanke Apartment, which is the "Changsheng Bio" company.

It means he ran away from most of the demon city, but he went around and returned to the starting point.

In my memory, he once passed by the gate of this pharmaceutical factory, and the traffic was endless, as if it was a relatively large factory.

Security measures seem to be quite strict. I remember that there are at least eight security guards guarding the door when commuting to and from get off work.

Since he found the source of the smell on Lilian's body, Gao An was not so anxious to find the person who had a joint with Lilian.

The environment in broad daylight is not conducive to finding people.

On the one hand, there are many people and eyes, and on the other hand, there must be many cameras in the factory.

Even if he can fast forward his speed and even increase his speed to supersonic speed, he will still leave clues on the camera.

With such a big factory, his cameras must be high-end products. He can't detect him at twice the speed. He will investigate frame by frame and reveal his figure sooner or later.

Just in case, he decided to act again at night.

First, I went to the convenience store to buy enough food for Xiaohua and bought some mineral water for myself. Each person and a cat were nestled in the car and listened to the raindrops slapped the roof and windows.

The security guards in the factory were not surprised by this. After all, there were a lot of black car drivers waiting to solicit customers at the gate, and not many more of them.

At 5:30 pm, Changsheng Bio Factory began to gradually release the work. Physical industries like them usually go to work at 8:00 in the morning, take a break at noon, and get off work in batches at 5:00 in the afternoon.

The purpose is to miss the rush hour for get off work, after all, the traffic in the Magic City is too congested.

Other black car drivers also got out of the car and started taking on jobs. Gao Ang also pretended to walk to the downwind, and began the "Star-sucking Technique" towards the crowd coming and going.

This does not match, and it only has about 20% overlap with Lilian's odor molecules.

This is not in line with it, and it is also a coincidence of over 20%, which is slightly higher than the one just now. Well, maybe it was because of a woman who went to the women's bathroom?

I sucked several people in a row, and there was almost a overlap of about 20%, and there was no one higher.

Some of the workers who left the factory gate were laughing and joking with their companions, some took off their badges silently and got on the black car and left directly, while others walked along the road to the nearby bus stop and waited for the next bus to arrive.

Well? The overlap of odor molecules of these people has increased significantly, directly from 20% to 35%, but it is not enough.

After looking at their badges, they were all "Yangsheng Research". It seems that Lilian has also entered this area.

In the next period of time, Gao Ann discovered a few people who had a higher overlap than the previous few people. The brand was 'mmn laboratory'.

The overlap of these people is as high as 60%, which should be the highest overlap among those who go out.

But he still didn't find anyone who had overlap with the odor molecules on the ring, even none of them.

The people who came out of the factory were already sparse, and the security guard at the door had turned his suspicious eyes to Gao Ang many times.

In order not to attract their attention, Gao Ang had to get in the car, drive the car to the downwind, open the window and take out his cell phone, pretend to make a call, and then complain a few times, then hung up the phone, and even took a slap in the steering wheel.

The feeling that outsiders is that he waited for someone for a long time, and then was released with a pigeon or asked him to continue waiting, which led to a little irritable mood.

With these performances just now, the security guard finally took his eyes away because another group of people were about to get off work.

This group of people is more important than those before, because they face more stringent searches and inspections.

Before, the workers had swiped their cards and tested metal foreign objects to get out of the door.

These people have to enter the security room. As for what happened in the security room, it is unknown.

Fortunately, there were not many people in this group, and after counting, it was only three people. The test was completed in a short while.

It can be seen that they are very respected by the security guards. When they walked to the door, the security guards waved their hands repeatedly and were polite.

Compared with other workers, the treatment of these three people is comparable to that of national treasures.

The most important thing is that these three people are all foreigners.

They should be speaking English, but unfortunately their high listening skills really failed. He has not spent any effort to improve his listening skills recently, so except for simple tone words such as ‘year’ and ‘ok’, the others are like listening to the heavenly book.

The three of them did not choose to black cars or buses, and walked directly along the roadside path where the high parking lot was parked.

When they approached the mini, Gaoang suddenly became clever.

Because he finally smelled the same smell as the ring's odor molecule. In addition to this smell, other odor molecules also overlap with Lilian's body, with a degree of overlap of up to 85%.

Although the overlap between the other two odors is quite high, even as high as 90%, these two people are not within the high lock range because they do not have ring odor molecules on them.

This shows a problem. Lilian should have met with those two people today, not that person.

Close the window and Gao Ang started to locate the person.

He is about thirty years old, about 180 years old, his face is slightly pale, and his eyes are dark circles and heavy bags. It is obvious that he is overused and extremely mentally exhausted.

My hair was a little messy, and my bangs were drooping. I guess I could hold my chin. My beard seemed to have not been shaved for several days, and my cheeks were covered with dense stubble.

A white shirt, black trousers, a pair of small leather shoes on his feet, and a cowhide file bag. If you don’t look at his hairstyle and face, you will think that this is a typical urban white-collar worker or gold-collar worker.

It’s a pity that his chicken coop and dead face completely ruined this image, which made Gao Ang couldn’t help but feel a little complacent: I’m more handsome than that.

The two people in front were talking and laughing, but they had no intention of communicating with the person behind them.

If it weren't for seeing the three of them go out together, Gao An would even think that they were completely two groups of people.

The three of them passed the first traffic light and Gaoqing did not move.

He lit the car when they reached nearly halfway through the next journey.

Um?

These three people did not pass the traffic lights, but turned left and entered Vanke Apartment!

This is interesting. Could it be that they were friends with themselves before?

But I have lived in this place for three years, but I have never met it once.

Or are they new?

But judging from their familiarity with the security guards and their postures and movements along the way, they don’t seem to have been moved here recently.

When the three of them disappeared at the turn, Gao Ang recharged the accelerator and followed him.

The railing at the door was not put down, and there was still a parking space in Vanke apartment.

The three of them did not turn left, but continued to move forward.

Turn left to see the accommodation building of Vanke Apartment. If you keep walking, you either go to the Four Seasons Hotel or go to the bus stop.

But if they want to take the bus, wouldn’t it be more convenient to have a factory entrance? So their destination should be Four Seasons Hotel.

After parking the car, Gaoqiang followed his smell, not far away.

As expected, the three of them really entered the Four Seasons Hotel.

After walking a few steps, Gao Ann narrowed the distance between the three of them. When he was about to follow them into the elevator, he was stopped by the hotel front desk in time.

"Sir, you can't bring pets into the accommodation area."

Hearing the sound, the three of them looked back curiously. Fortunately, Gao Ang had no direct contact with them before, so the three of them just glanced at him, swiped the card and entered the elevator.

He apologized to the front desk politely and embarrassingly, Gao Ang left the Four Seasons Hotel and returned to his car.

"Xiaohua, stay honestly, don't run around. If you are hungry, eat these. This is spicy, this is garlic-flavored... Also, don't make claws randomly, can you make them?"

"Meow."

Xiaohua interrupted his nagging impatiently, jumped to the back seat and started a hand-to-hand fight against a bunch of snacks.

After taking out a cash clip from his little bag, counting a few more cash, Gao Ang then turned around and returned to the Four Seasons Hotel.
Chapter completed!
