I'm a Super Cop

7 p.m.

Riverside Park.

An hour before the official fireworks show, but the scene has already been crowded.

After parking in the underground parking lot of a shopping mall, Gu Chen and everyone went on foot.

In order to avoid traffic jams, Gu Chen even chose to park a kilometer away from Binjiang park.

But even so, Gu Chen underestimated the determination and will of the people in Jiangnan City to get together.

Walking to the riverside park, the formation has become: everyone, everyone, officer Wang, Lu Weiwei, Gu Chen, Nie Xiaoyu, master Nie, everyone.

Afraid of being scattered in the crowd, we simply hand in hand.

But even so, Gu Chen was still squeezed by a group of high school girls, and I don't know how many footprints he stepped on.

People wear casual clothes when they go out at night.

Nie Xiaoyu and master Nie are wearing white sweater and sports casual pants, which make people know that they are father and daughter at a glance.

Gu Chen and Lu Weiwei wear red sports suits and small white shoes.

Of course, it's not a coincidence

Lu Weiwei will not tell Gu Chen that she secretly bought a set of women's suits of the same style according to Gu Chen's clothing style.

It's called the same eye.

Of course, this is not the first time

Lu Weiwei has two or more sets of clothes of the same style as Gu Chen.

To make a couple's clothes

Unlike the casual wear of Nie's father and daughter, and the sportswear of Gu Chen and Lu Weiwei, officer Wang is wearing a plaid suit with leather shoes.

Mature firmly occupy the C position

The style of his suit is the latest, which imitates a big brand's new style in autumn.

After buying his wife's and daughter's clothes, he made use of his last savings to get from 500 yuan of ocean to 100 yuan of ocean in the night market.

Although it is cheap, it still looks like a famous model uncle when wearing it on Comrade Wang's strong body.

After all, they often can't accompany their families, so it's better to give more change to his wife and daughter. Lao Wang thinks that This is a good way to compensate.

There are more and more people. At some crossroads, some police cadets are keeping order.

With traffic lights as signals and sidewalks as the basis, people are pulled up to effectively separate the crowd from the traffic flow.

On the main square of the riverside park in Jiangnan City, it has been separated by the organizers with guardrails. Here is the main venue where fireworks are blooming, and the number of people in the periphery is the most.

In recent years, fireworks are no longer allowed to be set off in the urban areas on holidays, so that the city is becoming more and more stale.

Especially after the ban on fireworks, babies born after the promulgation of the ban on fireworks, have no idea what fireworks are? There's no concept at all.

The official set off also touched many people's memories for many years, so many of them came to watch the fireworks feast with their families.

"Did you hear that? This fireworks feast was written by the fireworks master of Jiangnan City. "

"You mean Jiang Wentao? That's a great international fireworks master. "

"I've heard of this man before, but I don't know. He's a native of Jiangnan City?"

"It's said that many large-scale international fireworks shows are from the team of Mr. Jiang Wentao. It's wonderful to hold such fireworks shows in Jiangnan City."

"Yes, you can see from the car that there are not only local media in Jiangnan City, but also many media from other provinces and cities, even from Beijing."

"Mr. Jiang Wentao is very powerful. He has such a great influence. It seems that he has a good eye tonight."

While waiting, many tourists began to chat about the deeds of fireworks master Jiang Wentao.

After listening, master Nie turned to Nie Xiaoyu and said, "so Jiang Wentao is so famous in the world?"

"It's true that their team has 30% participation in the major international fireworks shows." Nie Xiaoyu also said what he knew.

Gu Chen also said with a smile: "this fireworks show, the explosion time of fireworks bombs is controlled by the chip."

"Core Chip control? " Lu Weiwei on one side directly froze, way: "so fierce? Can the explosion of fireworks be controlled by chips? Lao Wang, do you know this? "

Lu Weiwei quickly turned her eyes to officer Wang.

"Well, it seems that I have heard of some of them." After thinking for a moment, officer Wang looked at Gu Chen and asked, "Gu Chen, do you know anything about this?"

"I know something about it." Looking at the fireworks display, Gu Chen said: "for example, in a large-scale fireworks show, the shape of the most common" fireworks tree "can't show a strong dynamic feeling without the support of science and technology."

"Yes, we used to see some" firework trees "on TV. The strong dynamic feeling was really amazing. I was thinking at that time that such a dynamic feeling was actually presented by fireworks. What is the basis of this dynamic feeling Nie Xiaoyu can't wait to interrupt."It's technology." Gu Chen also smiles, saying: "fireworks all over the sky should be" danced "with the music. There will be a delay effect in rhythm, and the sound of fireworks should correspond to the music rhythm."

"So every important firecracker has a chip, and the chip has a time setting. If you master the explosion time of each pyrotechnic bomb, you have to calculate it."

Lu Weiwei can't wait: "if this is the case, it will be wonderful. I heard that not only will there be fireworks, but there will also be fireworks with the words" Jiangnan City. "

"And Can we have subtitles? " Police officer Wang couldn't believe it, and asked Gu Chen, "isn't this more difficult than pyrotechnics? After all, the firework tree is a three-dimensional thing, with a sense of picture, but if the subtitle is not good, it will make a joke

"Elder martial brother Wang is right, but it is a mature technology to form characters in the air." Gu Chen's words instantly dispelled Wang's worries.

At this time, a group of female middle school students who came to see the fireworks show also looked curiously at Gu Chen, saying that the little brother knew a lot.

A girl with short hair asked Gu Chen curiously: "it's OK to arrange the position on the ground for the formation of Chinese characters in the air."

Gu Chen took a look at her and said with a smile: "yes, but it's not so simple. Like the big footprints of the opening ceremony of the Beijing Olympic Games, they are all single line horizontal fireworks, which can be launched synchronously by platong troops on the ground."

"That's just putting the shape on the ground." Another tall and thin girl with a ponytail said that she could finally plug in.

Gu Chen said with a smile: "in fact, it's very difficult to launch because if you want to type the character" Jiangnan City "to a height of 300 meters, the final area of the characters will reach nearly 300 square meters. If it is too far away, it will not be able to outline the shape. If it is too close, it will paste together. Therefore, the launch time difference is only 100 milliseconds."

"100 ms?" Lu Weiwei is also a Leng, she certainly knows the concept of seconds, but millisecond that can be more accurate.

Gu Chen looked at the set-up fireworks shooting modeling in the central square, but he couldn't help sighing: "a 25 meter high fireworks tree rises into the sky, full of high-tech feeling, but the explosion time of the fireworks bomb is controlled by the chip, which is much better."

"Gu Chen is right." Master Nie has participated in the security work of some large-scale shows, especially some fireworks shows outside the venue. He stood beside him at the beginning and had in-depth communication with the staff.

Therefore, he can learn from Gu Chen's words what is high technology.

"It can be said that all links have a strong scientific and technological content, such as the wireless excitation used in the theme performance, the light and shadow group diagram, the sound setting and lighting setting of the whole mass get-together. New technology is reflected in the arrangement all the time."

Listen to the old father Nie comrade's words, Nie Xiaoyu also stunned, weak asked: "Dad, you also know these?"

"Dad used to be a policeman, don't you understand?" Comrade Nie was elated and said, "I know how these people operate."

"Master NIE is right." Now, there is a huge fireworks net design, which is the same as that of the past ten years

"But now, the whole sky on the square is used as a drawing board. Through the setting off of fireworks at high altitude, hollow and low altitude, the fireworks actually seen are a painting work."

A group of high school girls suddenly exclaimed, "is it so powerful?"

Gu Chen said with a smile: "I'll see you later. What I said can't be wrong."

The girl with short hair asked weakly, "what's your little brother's job? Is it fireworks? "

"Yes, you know so much. It seems that you have mastered all the unique skills of Jiang Wentao, the master of fireworks in Jiangnan City." Another tall and thin girl with a ponytail asked.

We all want to know what we are interested in. People always try to understand what they don't know, just like the first discovery of electricity.

What does electricity bring? At that time, many people only thought that this was a great invention, but its principle and contribution were difficult to understand at that time.

So for these high-tech fireworks shows with chip technology, we all want to know more.

Of course, it's just pure interest.

Gu Chen shrugged: "I'm just interested."

As a matter of fact, Gu Chen occasionally saw these in a science and technology magazine.

All kinds of books in the library can solve many problems of human beings.

At that time, Gu Chen just flipped through it and remembered it carelessly.

"There are few people there. Let's go there." Gu Chen's ear, Lu Weiwei effective can't wait.

In the crowded walk, watching the fireworks show has become a more painful activity.

Fortunately, Lu Weiwei found an open space in Binjiang park. Her perspective was good, and there were not many key people. She immediately suggested that everyone go there together.Officer Wang cast his eyes at him and said excitedly, "there are really few people. You can find this place. How can we go there? The province is squeezed into meat sauce here."

"Dad, I'm thirsty. I'll go and buy some drinks." Nie Xiaoyu sipped the corners of his dry mouth.

Nie Xiaoyu has not drunk water since noon, so he is thirsty now.

Master Nie looked around and said, "now that there are so many people, I'm sure you'll be scattered later. Otherwise, you should go to the open space first. After I buy the water, I'll go there to find you."

"Master Nie, I'd better go." Then Gu said, "I'll go there in the morning."

Gu Chen then turned around and left. Master Nie wanted to stop him, but he couldn't catch up with him. He was pushed away by a group of people. He had to say at the back, "Gu Chen, be careful."

"Yes." Gu Chen raised his hand and soon disappeared in the crowd.

Binjiang park used to have a part of the canteen, mostly concentrated near the public toilet.

However, most of the people who come here are concentrated on holidays. The riverside park is not an important place to punch in.

So the snack bar was later closed

Most of the people who can do business here are mobile vendors.

However, it is not easy to find these mobile vendors today. Gu Chen has already made psychological preparations.

After passing through several streams of people, Gu Chen came to the outskirts of Binjiang park. He saw a parent with a child, chatting and laughing. Each of them had a bottle of water in their hands.

So Gu Chen stepped forward and asked, "excuse me, where did you get the water?"

"There's a kid selling water over there." The parent turned and pointed to the right side of a public toilet.

"OK, thank you."

Gu Chen struggled through the crowd and finally found a little boy selling water under the guidance of his family.

The little boy was about seven or eight years old, sitting on a step with a bag hanging from his waist.

Next to several cases of drinking water, there is also a handwritten signboard in front of it: mineral water is two yuan, which supports mobile payment.

When Gu Chen walked by, several tourists just left.

"Children, I want five bottles of water." Gu Chen took out his mobile phone and said.

"OK." The little boy skillfully took out three bottles from the carton and gave them to Gu Chen. Then he took out two bottles from them: "your 5 bottles of water, 10 yuan in total."

"It's mobile payment, right?" Asked Gu Chen.

"Yes." The little boy pointed to the two-dimensional code posted on the sign. One was WeChat and the other was Alipay.

"Sweep any one you like." Said the little boy.

Gu Chen smiles, opens wechat and starts to scan the code.

But when the mobile phone is turned on, the network signal has been in a bad stage.

The nearby mobile base station is far away, and there are many people. Gu Chen tried seven or eight times, but still failed.

The little boy stood up, craned his neck and looked at Gu Chen's mobile phone and asked, "is the network bad?"

"Yes, it was fine just now, but not now." Gu Chen said.

"Does the little brother have cash with him?" The little boy asked again.

Gu Chen quickly took out his pocket.

In addition to a palm sized note paper, there is only a pen.

Gu Chen turned out all his pockets and laughed helplessly: "I'm sorry, I didn't bring any cash."

Seeing the little boy's disappointment, Gu Chen said again, "I'll try again."

A few more minutes have passed

Several tourists left after paying cash, but Gu Chen's mobile phone network still didn't work.

Gu Chen's face is not very good-looking. He thinks that he took the initiative to buy water just now. As a result, he was disappointed and embarrassed.

"Is the Internet still not working?" The little boy also looks at Gu Chen in embarrassment.

"Well." Gu Chen nodded, and then said, "can you do this, kid? I'll shoot your QR code first, and then I'll pay you when I'm finished watching the show. Do you think it's ok

The little boy hesitated and scratched the back of his head. After staring at Gu Chen for a long time, he said, "well, I think you look like a good man. You should not cheat the child. Then you should take pictures first and pay me when there is a signal."

"Thank you, little friend." Gu Chen is also very surprised, he just casually said, also did not seriously, but did not expect the little boy actually agreed.

"There should be some trust between people, which is what my father told me." Said the little boy.

Gu Chen touched his little head with a smile and asked, "what about your father?"

"He sells water in another place." The little boy also smiles at Gu Chen.

Gu Chen looked around and wanted to find an adult, but the little boy said again, "he doesn't sell here. You can't find him."

"All right." Gu Chen took out his mobile phone, took a picture of wechat QR code, and said, "I will definitely give you the money. Then I will take away the five bottles of water?""Mm-hmm." The little boy nodded for sure.

They exchanged greetings and left.

Soon, Gu Chen through the vast crowd, and finally meet in the agreed place.

"Brother guchen." Nie Xiaoyu first found Gu Chen and waved to Gu Chen: "here it is."

Gu Chen handed the water to her and said with a smile, "it's hard to find water tonight, and the signal is not good here."

"I found it, too." Lu Weiwei also held up her mobile phone to debug and said, "I asked Xiaoyu to take a few beautiful photos for me. Up to now, the circle of friends hasn't sent it successfully. Why is the signal so bad today?"

"There are so many people." Officer Wang took over the mineral water from Gu Chen and said, "the mobile base station here was demolished and repaired some time ago. Today, you can see how many people there are here. Can the signal be good?"

"When you come to the scene, you can't take photos, you can't send friends. Do you still have a soul for such a fireworks show?" After Lu Weiwei adjusted the angle again, she was surprised and said, "ah? Finally, it's ready to be sent. "

"Ha ha." Officer Wang also couldn't help laughing twice and said, "you're here to take photos?"

"Aren't you?" Looking at officer Wang, Lu Weiwei said, "Lao Wang, don't forget your task tonight. When the fireworks show is going to be held, shoot it carefully. Your sister-in-law's 40 meter long broadsword has always been in your hand."

"Ha ha." "I said Lu Weiwei, this ancient woman, could recite poems to be right, but why now women can only be right?" Wang said

"Today's women not only can recite poems, but also have both literature and martial arts." Lu Weiwei unexpectedly added another sentence, firmly occupying the high-pressure situation of Comrade Wang.
