After returning home, Xiao Zhen recalled that Xiao Yang always felt that it was not right. However, in the end, I didn't understand what was wrong. And it is really amazing to encounter stocks in Monopoly, so I asked Lao Wu what is a stock.

Lao Wu: "Haha, how do you talk about this thing?"

Xiao Zhen: "I didn't pay attention to it when I ran into it suddenly, but I saw someone on the street discussing this red and green, but this thing suddenly interested me." ”

Xiao Zhen naturally won't say what he encountered when playing Monopoly on the computer, but he couldn't think of where he would come across it, so he made up a random reason.

"Oh. That's right. Stocks, that is, some companies, because of the development needs to build a large factory building or something, but find that the funds are not enough, so through this thing to raise this money from other places is a kind of note. Lao Wu said.

"What does red and green mean? Xiao Zhen asked again.

"The value of the bill will change according to the situation of people trading the bill, and the red one in China means that the value of the bill has risen, and the green one means that the value of the bill has fallen. Lao Wu thought for a while and said.

Xiao Zhen wanted to ask something, but Lao Wu interrupted and said, "Okay, this knowledge is not what you should know now, why should you go, I want to read a book." ”

After speaking, Lao Wu picked up the 7610 mobile phone, and Xiao Zhen saw Lao Wu's appearance, so he also walked back to the room with interest.

After passing by the living room, I happened to see today's stock market on TV, and my grandparents kept watching, so Xiao Zhenzhen naturally asked about my grandparents again. However, the grandparents didn't seem to be able to say, and in the end they just said that it was a financial tool, and some people made a fortune through it, while most people didn't make any money. And this happens to be a bit similar to the situation encountered by Xiao Zhen playing Monopoly, only the one that Xiao Zhen occasionally buys succeeds in winning, and other times Xiao Dream buys is a heavy loss.

However, after a night of doing it, Xiao Zhen still couldn't understand what it was, so he simply threw it aside. On the weekend, Xiao Zhen still came to Xiao Jie's house to prepare for the final of the mini four-wheel drive.

Both of them carefully inspected each part, applied lubricating oil to the corresponding parts, and replaced the motor with new carbon brushes, after all, the consumption of carbon brushes by shock motors and atomic fission motors is very fast. And after the two of them changed the carbon brush, Xiao Hao also ran over, and saw Xiao Hao who had gradually recovered his mood, and the two were relieved.

The trio took their mini 4WD to the 4WD track in the city center for a final test run. Naturally, all three of them have changed to the best configuration for this competition.

I saw that the mini four-wheel drive cars of the three people had successfully passed the roller coaster track for ten consecutive laps, and the children around them all showed envious looks, after all, such a well-equipped mini four-wheel drive car is a dream for these children.

"Then it's up to who's lucky. Xiaojie said.

"Don't be like this, it's a bit scrappy. Xiao Zhen said.

"The speed of the three of us on this track is 0.04 seconds off. At this point, the game is really unclear. Xiao Hao touched his head and said.

After coming to the school for Monday's morning meeting, you can see that the runway for the finals has begun to be installed under the rostrum. Xiao Zhen and Xiao Jie naturally ran to the runway early to experience this new runway, but the staff bar said on the periphery that they could not touch it until the runway was fully installed. So I had to give up.

In the afternoon, it was the agreed time with Xiaomeng, but Xiaomeng didn't seem to be thinking about the mini four-wheel drive at all, and kept discussing "Monopoly" and stocks with Xiaozhen. So Xiao Zhen said: "Now it's the mini four-wheel drive final, can you do this thing first." ”

"However, now I think "Monopoly" is more attractive to me, especially the stock play you found, which is very exciting, and sometimes no real estate can directly rely on this to turn around. Xiaomeng said.

"But it's just a game, and this mini 4WD is my dream, and it's been going on for more than two years. Xiao Zhen said.

"Well, let's play this after the game. Xiaomeng said.

So the two began to practice operating the four-wheel drive car again, and Xiao Zhen helped Xiao Meng change the carbon brush.

By Wednesday, the school had already been installed, so everyone took the mini 4WD and started to try it out. Because this new track is really special, everyone was ready to test the car, but because they didn't understand what could go wrong, no one dared to try it, although there were a bunch of people around with mini four-wheel drive cars in their hands.

"I didn't expect to be here to watch, but I don't know who will be the first to eat crabs. Xiaojie said.

"I'm here, I don't have time to spend with them, I have to go home early. Xiao Hao walked to the starting point and put the car down. Since the finals are run for the sake of spectacle, they are lit, and the roller coaster also has five laps and a very sharp corner, which is generally a difficult track. The most difficult part is the five consecutive nearly parallel corners before the finish line, and if there is a slight problem with the guide wheels, the car will drift off the track. But this is not a problem for Xiao Hao, I saw that Xiao Hao's Spider King ran the whole course at a very perfect speed, and the shell of the Spider King looked extraordinarily chic against the background of the orbital aperture.

"Perfect operation. Let's try it too. Xiao Zhen said.

So Xiao Zhen and Xiao Jie also had a test run. I ran well all the way.

"The runway is good. I feel that I can make use of the effect of the whole car. Xiao Zhen said.

"But it shouldn't be that simple, I feel like there's still a lot of things on this runway that haven't been turned on. Xiaojie said.

"Also, there are so many strange threads that don't seem to be connected. Xiao Zhen said.

"It doesn't look like it's going to be easy. Xiaojie said.

"Haha, that's interesting. Xiao Zhen said.

"Also, it's good to have suspense. Xiaojie said.

There was an accident on the other side of the runway, and a mini 4WD that weighed too much and flew directly out of the last two corners of the track and crashed directly into the concrete wall.

Looking at the smashed mini four-wheel drive, the child's tears flowed all over the ground. However, it was useless for him to cry no matter how much he cried, his mini 4x4 could no longer be repaired, only a pile of debris and scattered batteries, motors, bearings.

Though a companion immediately went up and held the child, the child's tears were still hanging there, and he was still muttering something to his mouth.

Seeing this scene, Xiao Zhen and Xiao Jie naturally looked at each other solemnly, as if they were reminding each other to pay attention to protecting their mini four-wheel drive vehicles and to pay attention to the operation before going to the field.
