In the summer, Lillian must turn on the air conditioner and close the windows when she goes out, so as to isolate the diffusion of odor molecules.

The reason why it is still relatively obvious around the villa is because when she got home, she got out of the car, and the odor molecules on her body had room to volatilize.

It seems that it is difficult to find her destination directly with a single scent molecule.

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

"NO, what's wrong?"

"The MINI turned it on for me and my air conditioner broke. ”

That's right, Gao hit the idea on the MINI.

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

Got the key, got into the car and lit the light, one person and one cat squatted at the position of the exhaust pipe at the rear of the car, and breathed in the exhaust gas.

As soon as she sniffed it, Xiaohua couldn't help but sneeze, slapped her hand away, and ran into the MINI car in disgust.

"You kid, it smells so good. ”

I am not afraid of being embarrassed when I say it, Gao Gao liked to smell this smell when he was a child, and at that time there were generally no cars, but there were motorcycles and tractors.

If you have nothing to do, you follow the butt of the tractor, and occasionally take such a big sip, and the nasal cavity is full of that fragrant smell, and the whole person is much more comfortable.

It wasn't until he was in junior high school that he realized how stupid this behavior was.

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

So from then on he stopped chasing the tractor, but hid in the toilet and began to breathe in the aroma of nicotine.

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

Although the weather was gloomy, fortunately there was not much wind, and the scent molecules were still floating on Lilian's way back and forth, which did not cause much trouble to one person and one cat.

"How could it be here?"

Looking at the gilded words "Immortal Creature", Gao Gao realized why he was so familiar with the smell on Lilian's body.

This smell is the smell of the pharmaceutical factory near Vanke Apartment, that is, this 'Changsheng Bio' company.

It is equivalent to saying that he ran most of the magic capital, and he still returned to the starting point after going around and around.

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

The security measures seem to be quite strict, and I have the impression that there will be at least eight security guards guarding the gate when commuting to and from work.

Now that he has found the source of Lilian's scent, Gao Gao is not so eager to find the person who connects with Lilian.

The environment in broad daylight is not conducive to him looking for people.

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

Even if he could fast forward his own speed, or even increase it to supersonic speed, he would still leave a trail on the camera.

In such a big factory, people's cameras must be high-end goods, and they can't find him at double speed, check frame by frame, and sooner or later his figure will be revealed.

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

First, I went to the convenience store to buy enough rations for Xiaohua, and also bought some mineral water for myself, and one person and one cat nested in the car and listened to the raindrops lapping on the roof and windows.

The security guards in the factory were not surprised by this, after all, there were many black car drivers waiting at the gate to solicit customers, and there were not many more than him.

At half past five in the afternoon, the Changsheng Biological Factory began to gradually release the flow, and entities like them generally go to work at eight o'clock in the morning, take a break at noon, and start leaving work in batches at five o'clock in the afternoon.

The purpose is to miss the rush hour, after all, the traffic in the magic capital is too congested.

The other black car drivers also got out of the car and began to pick up work, and Gao Gao also pretended to go downwind, and started the 'star absorbing method' against the crowd.

This, not compatible, only coincides with Lillian's odor molecule by about 20%.

This, which doesn't match, is also a degree of overlap in the early 20s, which is slightly higher than the one just now, well, probably because of women, went to the women's toilet?

'sucked' several people in a row, almost all of them had a degree of overlap of about 20%, and there was no higher one.

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

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

Looking at their badges, they were all 'Immortal Research', and it seemed that Lillian had also entered this area.

In the next period of time, Gao Gao found a few people who overlapped more than the previous ones, and the brand was 'MMN Laboratory'.

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

But he still didn't find anyone who had a degree of overlap with the scent molecules on the wrench, not even one.

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

In order not to attract their attention, Gao Gao could only get in the car, drive the car to the downwind, open the window and take out his mobile phone, pretend to make a call, and by the way sent a few complaints, and then hung up the phone fiercely, and slapped the steering wheel.

To outsiders, it feels like he waited for someone for a long time, and then he was released or asked to keep waiting, which caused him to be a little irritable.

With these performances, the security guard finally took his eyes off him, because another group of people were about to leave work.

This group of people is more important than those who came before them, because they are also subject to stricter searches and inspections.

Before, those workers swiped their cards, did the detection of metal foreign objects, and then they could go out of the gate.

These people are going to enter the security room, and it is unknown what happened in the security room.

Fortunately, there are not many people in this group, and the number of people is three heads, and the test will be over after a while.

It can be seen that they are very respected by the security guards, and when they walked to the door, the security guards waved their hands politely one after another.

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

The main thing is that all three of them are foreigners.

They should be speaking English, but unfortunately Gao Gao's hearing really failed, and he hasn't bothered to improve his listening recently, so except for simple 'Year', 'Ok' and other modal words, the rest is like listening to heavenly books.

The three of them did not choose a black car or a bus, and walked directly along the roadside path where they parked at high cost.

When they approached MINI, Gao Gao's whole person suddenly became smart.

Because he finally smelled exactly the same smell as the wrench scent molecule, and in addition to this smell, the other odor molecules also overlapped with Lilian's body, with a degree of overlap of up to 85%.

Although the overlap of the other two flavors is also quite high, even as high as 90%, these two people are not in the range of the high lockdown because they do not have a wrench odor molecule on them.

This shows that Lillian should be meeting with those two people, not that person.

Closing the window, Gao Gao began to locate the man.

He is about 30 years old, about 180 years tall, with a slightly pale face, dark circles under his eyes, and heavy eye bags.

The hair is a little messy, the crooked bangs are drooping, I guess I can touch the chin, the beard looks like I haven't shaved for several days, and the cheeks are covered with dense small scum.

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

It's a pity that his chicken nest head and dead face completely ruined this image, which made Gao Gao feel a little complacent: Compared to us, we are still a little handsome.

The two people in front of them were talking, laughing, and laughing, and they didn't mean to communicate with the person behind them at all.

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

The trio passed the first traffic light and did not move.

It was only when they were nearly halfway to the second traffic light that they ignited the car and started the car.

Well?

These three people didn't even cross the traffic light, but turned left into Vanke Apartment!

This is interesting, could it be that they used to be friends with themselves?

But I've lived in this place for three years, alas, and I haven't met it once.

Or are they new here?

But judging by their familiarity with the security guards, and the postures and movements along the way, it doesn't look like they moved in recently.

When the three figures disappeared around the corner, they followed as soon as they stepped on the accelerator.

The railing at the door has not been lowered, and there is still a parking space in the Vanke apartment.

Instead of turning left, the trio continued to move forward.

Turn left to the accommodation building of Vanke Apartment, and if you keep walking, you will either go to the Four Seasons Hotel or go to the bus station.

But if they want to take the bus, the factory entrance is more convenient, so their destination should be the Four Seasons Hotel.

Park the car, hold Xiaohua in his arms, and follow his scent not far away.

As expected, the trio did enter the Four Seasons Hotel.

Walking a few steps briskly, Gao Gao narrowed the distance between him and the three of them, and when he was about to follow them into the elevator, he was stopped by the hotel front desk in time.

"Sir, pets are not allowed in the accommodation area. ”

Hearing the voice, the servants glanced back with a little curiosity, but fortunately, Gao Gao had no direct contact with them before, so the three of them just glanced at him, swiped the card and entered the elevator.

Politely and embarrassed, he apologized to the front desk, and left the Four Seasons Hotel and returned to his car.

"Xiaohua, stay honest, don't run around, if you're hungry, eat these, this is spicy, this is garlic-scented...... Also, don't you make it with your claws?"

"Meow. ”

Xiaohua interrupted his nagging impatiently, jumped to the back seat and faced a large pile of snacks, and began a hand-to-hand fight.

He took out a wallet from his small satchel, counted a few more bills, and then turned around and returned to the Four Seasons Hotel.
