Ten minutes later, Jiao Wei and the man who had retrieved the model airplane from the tree came over.

The man who was playing with the Rubik's Cube rested the Rubik's Cube with the six colors on a wooden shelf next to it.

The wooden shelves are old, there are a lot of scratches on them, and the legs of the shelves have been cut. The shelves, as well as some similar tables, chairs, benches, etc., in this building, have been repaired to varying degrees, and the repairs are much newer than the original ones, but they are also worn out, and it seems that people often come to this place.

"Now that we're all here, let's get started." That Senior Brother Cheng got up and said.

Zheng Si stood on the windowsill and watched these people take out model cars one after another, the appearance was a little different, some were like miniature sports cars, very exquisite, some were like miniature off-road vehicles, and some were like unfinished works, the shell was incomplete or not installed at all, and some parts inside were exposed.

These people are indeed playing with toy cars. Zheng Si can't care about despising them now, to be honest, Zheng Si actually has such a sour grape mentality, who made him not even have a toy car now.

On the cleaned field inside, there are several circular runways, one ring is covered, each circular runway is different, some are relatively flat, some are sprinkled with sand, some are thrown some small stones in it, and some circular runways are also set up with slopes, as if simulating different road conditions.

There were other Zheng Si who didn't have time to observe, because several people had already placed their toy cars on the relatively flat runway. After the countdown, four miniature sports cars were running.

All four cars were running fast. Compared with Liu Yao, the controllers here are much more capable, and there is an age factor, probably because these people are all veterans.

After staring at the car on the runway for a while, Zheng Si suddenly felt that something was wrong, and after thinking about it, he realized that it was too quiet.

Liu Yao's muffled bear child who has a bad temper and stinks won't talk about it, and it doesn't look like an introvert here, just now Zheng Si heard them brag and fart and chat, but now it stands to reason that it should be time to shout and cheer. But eerily quiet.

Of course, the sound of the car running is the most clearly heard. There was no cheering or cheering as Zheng Si expected. Is this how older children look when they play with toy cars? Won't you shout excitedly like a child?

Zheng Si shifted his attention from the running car to the people standing on the edge of the runway.

The four people in control of the toy car stood there, their expressions changing with the movement of the car, nervous, excited, or annoyed, but they didn't make a sound. As for Jiao Wei. He's the same as the others. While looking at the toy cars running on the track. He still has a notebook in his hand to record something. A few steps away from them, there were still people staring at the instruments on the table, and Zheng sighed that he didn't know what it was for.

About ten minutes passed. Zheng Si heard Senior Brother Cheng shout "Stop", and the four cars stopped.

Finally, after ten minutes of silence in this sports car, it was noisy again, and it was quite intense, much more lively than before it began.

It's just that in the words that Zheng Si heard, there were very few questions about speed and ranking, what coefficients these people were talking about, what equations were they talking about, and some things in theory and technique Zheng Si didn't understand, even if he saw the data on the pages of paper in their hands, Zheng Si was like reading a book from heaven.

It seems that these people do not have the attitude of playing with toys, but go deeper and strive for excellence?

Jiao Wei estimated that because he was a newcomer, he didn't talk much, most of the time he was taking notes, listening to other people's explanations and suggestions, and when he looked up and was about to talk to someone, he suddenly found a black cat standing by the corner window and stretching his neck to look at this side.

Jiao Wei: "?!! ”

He didn't even have to look up close or call out his name now, he could recognize the cat at a glance!

How did it get here?! Jiao Wei suddenly had a premonition that he was not very good.

The person next to Jiao Wei noticed his strange appearance and looked over, and also found Zheng Si.

"Hah, there's a cat watching our sports car again." The man said.

"Again?" Jiao Wei looked at the people around him suspiciously. He thought that these people would be surprised, but he didn't expect most of them to be calm.

"Well, there are old houses all around here, and there are not many people living in them now, and there are often cats hanging around, and occasionally curious cats come over, but not much, after all, most cats are still quite timid." The man explained.

Because of this, even if someone found Zheng Si squatting at the window and looking at this side before, no one made a fuss.

But this one is different. Jiao Wei muttered in his heart.

Now that he has been discovered, Zheng Si didn't hide anymore, but he didn't jump in, and squatted there on a closer windowsill to continue looking.

These people ran a few rounds, each round of the model is different, the track is also different, and after the run, although they also talk about the results after the run, it is more about some topics in technical skills, and those Zheng Si are completely amateurs.

When he was a human being, Zheng Si bought a car, and someone gave him a model car, and he put it there as a toy, and many people used it to collect. Most people still think that those who use the remote control to control the toy car running outside are children who have not grown up, at least Zheng Si thinks so.

Zheng Si didn't know how much progress Lu Dao had made in car models a few years later, and he didn't bother to know much, but now he was really interested in seeing these people playing with model cars.

After that day, Zheng Si often came to this area in the afternoon, basking in the sun on a low blue-tiled house not far from this old house, and went over to watch when he heard the movement inside.

After two weeks, Zheng said that these people would come here every Monday and Thursday at 3 p.m. to run. These people come from different faculties, including mechanical engineering, electronic information, mathematics and statistics, as well as people from the Faculty of Physics, the Faculty of Chemistry and other faculties, who come together because of their common hobbies. And the leader of these people is the "Senior Brother Cheng". As for the more detailed Zheng Si, it is not clear, it is too difficult to inquire about the news.

These people come over every time they come over to "sports cars". They will also bring some simple and portable instruments, after completion, they should take away what should be taken away, and those who are too lazy to take away will be directly put in cardboard boxes and put on high shelves, and when they leave, they will also close the doors and windows of this building, lock the door, and the things left here are not too valuable, and they are not worried.

And these people also knew the origin of Zheng Si from Jiao Wei's mouth, and they knew that he was a teacher's cat in the Academy of Biological Sciences. I am familiar with Jiao Wei. So every time they see Zheng Si watching, they will also give a snack or something.

It's a pity that Zheng Si didn't appreciate it, and he glanced at those snacks and never looked at them again. There are also people who want to tease the cat, dangling the wool rope or throwing a tire and rolling around to attract Zheng Si's attention, Zheng Si looks at them like a fool. Then I turned my gaze back to the model cars running on the runway.

Can't get a car. It's always okay to get over the eyes.

After getting acquainted with these people. Zheng Si no longer stayed on the windowsill every time he came, and simply entered the house and stood on the high shelf. Condescendingly looking at the situation below.

At five o'clock, the men finished and began to pack their things one by one.

Zheng Si jumped down from the high shelf and was about to leave, and when he jumped on the windowsill, Zheng Si suddenly heard someone talking about himself behind him, and his steps slowed down.

"Why do you think cats are interested in this kind of toy car?" Someone asked, looking at the black cat on the windowsill with its back to them.

"Cats are inherently interested in this kind of small, moving thing, so it's no wonder."

"That's not it, my sister's family jumped away when they saw this, let alone watch from the side."

"Don't all cats like to be furry? It's all a bunch of hard materials or parts. ”

"My uncle's cat likes to squat next to watch my nephew play with the remote control car, but it just doesn't get close to it."

……

Hearing these people's discussions, the corners of Jiao Wei's mouth twitched. These people were not familiar with the black cat, and looked at him like an ordinary cat, but he knew that the black cat was probably listening to the conversation of these people, and didn't he see that the standing cat's ears were turned to the side? And that rhythmic hooking tail also proves that the guy is thinking about something.

It's just that Jiao Wei can't say what he thinks in his heart, Associate Professor Jiao once talked to him, and Jiao Wei remembers the things to pay attention to about these cats on weekdays, so he is also talking about it in his heart now.

After Zheng Si returned to Jiao's house for dinner, he thought about it for a while, and then ran out of Lu decisively.

The target is the old tiled housing area. Zheng Si's mind these days is full of those running model cars, to be exact, the kind of miniature version of the car. Some of the model cars in those hands can no longer be called toys, they are all "high-end goods" full of technical content.

During this time, I have been thinking about cars, so much so that one day when I was lying on a branch basking in the sun, I heard two college students walking below talking about the topic of "car model", and Zheng Si's first reaction turned out to be "car model" instead of "car model"! It wasn't until he heard the two college students talk about those beautiful girls who were either cold or flamboyant that Zheng Si reacted that this "car model" was not the other "car model".

Zheng Si suddenly felt that he was much purer, and he thought that when he heard the word "big wave", his thinking could be directly crooked.

Looking up at the sky, the moon is bright and the stars are sparse, which is not bad.

There are no street lights in the old tiled housing area, only a few lanes on the edge, and most of the other places are dim. It is estimated that the school feels that this area will be demolished and rebuilt sooner or later, and there is no need to change the street lights.

Zheng Si was walking along the path towards the house where Jiao Wei and their sports car were going, when he suddenly felt that he was being followed. Due to the direction of the wind, Zheng Si couldn't smell anything unusual, but Zheng Si could hear the slight sound of rubbing the grass, and, intuitively, Zheng Si felt that someone was watching him, but there was no malice.

A dark shadow jumped from the bushes and rushed straight to Zheng Si's side.

Zheng Si was vigilant, and knew the direction from the moment when the black shadow hadn't jumped up. Seeing that the other party pounced, Zheng Si jumped away and slapped a few times at the same time, with little force, just like the level of ordinary cat-to-cat play.

Zheng Si really didn't expect to meet the sheriff here, this guy hasn't seen much at night recently, and now it seems that he came here to play. Also, this old tile housing area is not too far from the East District Compound, and there are few people, many cats, and there are often ghosts howling at night. (To be continued......)
