As soon as they went up to the rooftop garden, Atletico was surrounded by the little ones, "Daddy is a liar, there is no big moon in the sky!"

Looking at the sky with your little hands, you can see that the dark and dreary overhead is overhead, and the usually bright and bright neon night scene is wrapped in a rain curtain, no longer in its former glory. On such a rainy night, it is natural that you can't see the Mid-Autumn Moon that should appear.

"It's not a good boy to lie to people, Dad didn't lie to you," Atletico was calm, raised the moon cake plate in his hand, and said: "When I put the plate away, I will call Sister Moon, and then she will come out to see you!"

The scent penetrated into the nostrils, and the children's attention was attracted by the pancakes, and their eyes were staring at it, and they couldn't take their heads off it.

Unmoved, Atletico followed the path indicated by the floor lamp with his plate and walked towards the garden sitting-out area.

The target ran away, and the little ones turned their eyes to the melon and fruit plate in their mother's hand, but what they got was a "What are you looking at? Why don't you go wash your hands quickly?"

Tang Qi stood up and took his granddaughter's little hand, "Let's go, grandpa will take you to wash your hands!"

Lu Wei was about to follow up, but was stopped by her daughter: "Mom, just sit down, let County Magistrate Tang behave well." ”

"You kid, how can you talk about this?" Tang's mother was suddenly unhappy.

"Did I say something wrong?" Tang Jiayi pouted: "An An stable life, when you are old, you don't want to enjoy Qingfu, what are you tossing?"

Because of his meritorious contribution to the development of education and the effective promotion of investment, Tang Qi, director of the Education Bureau, had the hat of deputy county magistrate on his head and officially became a member of the leading group of Yang County, in charge of education, scientific research and industry.

For this small mountain town, agriculture is the first pillar and tourism has the greatest potential, and other departments have to stand aside, so Comrade Lao Yang is actually still staying in Leng Yamen. Even so, the promotion still stimulated Comrade Tang's enthusiasm for work, so much so that he was so busy that he didn't come to see his grandson for several months, and the latter complained about it.

The mother and daughter were arguing, and Atletico suddenly interjected, "It's actually good to work there, the mountains and rivers are beautiful and the air is fresh, and it's a good place to raise people." If it weren't for the fact that I couldn't leave here, we would have been there to enjoy the moon and the mountains. ”

Tang Jiayi glared at him: "What's the matter with you?

was reminded by her like this, and the four children, who had already quieted down, also reacted and shouted "Sister Moon" one after another. The sound is reflected many times by the glass ceiling, and it is reminiscent of the kindergarten class that has just started.

The four adults hurriedly hugged a gentle word nearby to comfort them, which saved their ears from the noise pollution.

Grabbing the mooncakes and stuffing them into the hands of the children, Atletico reassured them: "Dad has already called Sister Moon, and she will come out immediately." ”

Then, he turned to the other people and said, "It's almost time, let's come here!"

Naturally, the children cheered and followed their father to the west side of the garden, followed by three skeptical adults.

The streetlights, neon, and landscape lights were still on, but they looked a little dull and sparse, as if they were listless.

It didn't make people wait long, as soon as everyone settled down, the world in front of them changed: the decorative lights of the buildings were extinguished one after another from the outside to the inside, and only a few street lamps were still stubbornly holding on, preventing the whole area from falling into darkness.

"Why is there a power outage?" Lu Wei wondered.

"Maybe it's a mistake to pull the wrong gate, don't do too many temporary workers these days," Tang Jiayi guessed with a smile.

"Don't jump to conclusions, pay attention!" Atletico said triumphantly: "Here's the moment to witness the miracle!"

As the words fell, some white spots suddenly appeared on the dark ground, and a bright moon suddenly appeared on the earth. The moonlight was white and blue, cold as usual, and you could see the bright moon land and the dim moon sea, as if the moon really appeared in front of you.

Of course, this is impossible, and the earth is still "unable to pull", causing the moon to flee outward at a speed of 38 millimeters per year, and no one will be able to pull it to the ground. Unless a myth descends, there is a great power that defies gravity.

Fortunately, the real moon can't be pulled, but people can make a fake one themselves.

A few days ago, some businesses on the island placed a model of the moon at the door and installed lamps for people to enjoy and take photos.

"Moon, Moon, Sister Moon!" the little ones screamed and jumped excitedly, leaning on the glass wall and shouting loudly.

As if their call had an effect, a black shadow suddenly appeared on the surface of the moon and grew larger, and then everyone saw a curvaceous female figure dancing and spinning on the moon, looking around, hugging the rabbit and feeling sorry for herself. Zhizhi and the others didn't know who Chang'e was, but they just kept shouting.

Seeing that everything was going well, Atletico quietly let go of his hanging heart and turned his head to look at everyone, "How about this Mid-Autumn Festival gift?"

"Okay," Tom nodded, "this light show is interesting, and everyone shouldn't be disappointed." ”

This year's Mid-Autumn Festival caught up with the typhoon to stir up trouble, although it was far away in the ocean, but it caused wind and rain on land, stirring up the interest of the general public to reunite and enjoy the moon. Fortunately, the Mid-Autumn Festival night light show announced by the bees in advance was not canceled, and many citizens still braved the rain to come, and the bees did not disappoint, and really came up with a novel and interesting performance.

"But how did you do it?" Tang Qi asked again, and then guessed to himself, "The pattern is so big, it shouldn't be possible to rely on ready-made lights or a sea of people, right?"

Then his guess was rudely interrupted by his wife, Lu Wei glared at him, "What do you care about, just watch it carefully!"

"Yes, yes!" Deputy County Magistrate Tang said that he had no opinion, and echoed in a loud voice.

"Don't just watch, come and eat mooncakes, I made them myself," Atletico hurriedly handed the plate to the three of them.

"It seems like there's something missing," he said suddenly, "yes, it's this." ”

Stuffing the plate into Tang Jiayi's hand, Atletico took a step back, replaced it with a commentary, and read it one by one: "Modern life simplifies traditional customs into standard consumer goods, so that the festival loses its original taste." The world has changed, people's hearts have changed, and the more convenient and easy to obtain machine-made food, the more yearning for the handmade taste of the year. The market is still prosperous and sufficient, but the most expensive and dazzling is no longer polished rice and white noodles, but the simplest pastoral flavor. ”

Sixiao didn't understand much, and only concentrated on dealing with the moon cakes in his hand, but Tang Jiayi asked suspiciously: "Why does this sound familiar?"

"Can you be familiar? Isn't it just the tip of the tongue!" Lu Wei said, she has seen the "tip of the tongue" back and forth several times when she has nothing to do in the mountains, and she is most familiar with the tone of such lines.

At this moment, she suddenly felt that her clothes were being pulled apart, and the cry of her little grandson came to her ears: "Grandma, grandma, Sister Moon is here!"

Turning his head to look outside, the moon pattern unconsciously moved a lot, gradually getting closer to himself and the others.

As the distance got closer, everyone saw the essence of the "bright moon" more clearly, it turned out to be bright or dark spots, arranged in a circle and moving on the ground, and these bright spots were lanterns flying from the sky. The lights hang in groups of seven under the drone, relying on the latter's swarm flight to cast a bright pattern on the ground, like a flashlight spotting the ground crawling around on the ground until someone presses the turn off button.

The multicopter itself is inefficient, with a stay time of no more than 30 minutes, which, combined with weather factors and headlight loads, makes the safe working time even shorter. So the whole performance didn't last long, after the two moon cakes were eaten, the "bright moon" was put away by the staff.

Although the little pot friends were a little dissatisfied, they couldn't resist their physical reactions, and soon dozed off under the drive of satiety.

One by one, the adults carried the sleepy little guy downstairs, and tonight's "moon viewing party" ended.

Coming out of the children's room, the adults didn't feel much sleep, the old couple of the Tang family went to the entertainment room to watch a movie, but Tang Jiayi followed Atletico into the study, she was quite curious about the result of tonight's performance.

There is no doubt that this performance has been a great success, and many people are talking about it with relish, whether it is local citizens or netizens from afar, and it directly steals the limelight from the Tiangong-2 laboratory that is about to go to heaven.

The principle of the show is not unusual, the ancients of the lighthouse era could have done it, but when it comes to fashionable things like drones, everything becomes unusual. There is no shortage of hundreds or even dozens of so-called pocket drones on the market, but the really practical drones have a lot of size and a lot of price, and these machines equipped with bright LEDs obviously belong to the latter, just think about millions worth of drones buzzing over the head, can make many people excited.

"Using 300 units at a time, it should be a record, right?" Tang Jiayi asked, she also knew the specific number after watching the news from netizens.

"It should be," Atletico laughed, "Aren't they not recognizing my 256 record, give them a 314 this time!"

"Virtue!" Tang Jiayi glanced at him, but her eyes were full of sweetness, and her thoughts couldn't help but go back to nine years ago.

At that time, Atletico Madrid built 256 miniature flying machines and performed a light show on the school square, winning the admiration of countless students and teachers.

Unfortunately, there weren't many camera phones at that time, and the camera performance was not good, and the performance did not leave much video to remember. Later, the statistics of UAV cluster flight records, no one calculated it, the lack of strong evidence is on the one hand, and the simple structure of micro aircraft and few functions are also the reasons.

Of course, Atletico Madrid didn't take it to heart, this time it was just in time for the rain and the moon to be seen, so he took out the original program to exert his residual heat, and then there was today's performance.

Or let the drone form a fixed array to act as a flight platform, or use an additional light control program to manage the lights, just replace the LED lamp beads with a high-brightness lighting group. The separation of the two subsystems from each other greatly reduces the difficulty of implementation, although the load is heavier, the pattern is more complex and detailed, the implementation difficulty is also not too great, even in the wind and rain It was successfully completed, and a wave of performance advertising was made by the way.

Others don't know the inside story, compared with the scale of dozens of military drone flight clusters, they will naturally think that the technology of bees has broken through the sky, but in fact, this is a beautiful misunderstanding.

Then Tang Jiayi naturally thought of striking while the iron was hot and using this misunderstanding to make a wave of publicity.

"It's sure to take the opportunity to publicize it, but you can't take advantage of the misunderstanding," Atletico shook his head, "This kind of misunderstanding is too unsafe, and when the time comes, it will become our fault if it is punctured." ”

As he spoke, he started with both hands, released the source code and related tools that had been prepared a long time ago, and then sent a scarf to explain the situation, encouraging netizens to download tools to design their own "sky display".

"This set of tools is the best match for our toy line, and we are the ones who benefit in the end. ”

"That's right," no longer paying attention to this topic, Tang Jiayi asked curiously: "Can you use a drone to form a sphere and directly simulate the moon?"

"Of course you can, but you can't do it, dear!" Atletico snapped his fingers and counted: "You won't forget the ball volume formula, right? It takes more than 500 drones to form a sphere with a diameter of 10, doubling the diameter and increasing the volume by eight times, and the number is directly up to 4000, who can afford it? Professional drones are not cheap, one 10,000 is 40 million." ”

"You know, professional machines are too expensive to use cheap products, aren't those mosquitoes you made back then very good?"

Atletico almost collapsed, "Dear, do you really think that we have broken through the wisdom of the cluster and can accumulate weak and strong, right? Those toys are not very useful, not to mention that they can't withstand today's wind, and they can't solve the problem of how to prevent rain." If you have this kung fu, you might as well get a big balloon and stuff it with projection equipment!"

"Then why don't you get balloons?" asked Tang Jiayi without raising her head.

Atletico Madrid replied: "The balloon looks simple, but the installation, control, and navigation are all troublesome, and it is better to use a drone, and it can also advertise by the way." ”

"Haha!" Hearing this, the lady's reaction was to laugh out loud.

"What's the matter, what's the coke?"

Long press to share the web page, Tang Jiayi said: "Someone made a big advertisement for you!"

Clicking on the page shared by the other party, Atletico couldn't help laughing, "This person must have done it on purpose, he is about to become famous." ”

On the monitor in front of him, the bold headline "Crazy Anchor Wants to Ride a Bear, Riding a Robot Bear" is full of the headline art of online news.

The article is about an interesting story that happened today.

During the Mid-Autumn Festival holiday, the mall zoo ushered in a large wave of citizens and tourists, and then a man took advantage of the unpreparedness, climbed over the guardrail and broke into the giant panda rest area, lying on the giant panda and quickly began to stir, and the companions who had been prepared around him pointed their mobile phone cameras at him and broadcast live on the Internet synchronously.

Their intention is obvious, just to make a big news, so that they can increase their popularity and fight for the position. As for the possible risks, people are obviously prepared, knowing that the two pandas in the mall are fake, and there is no right to fix them casually.

There were originally real pandas here, but one died of mismanagement and the other was recovered. Because of the failure to apply for loan after rectification, the park purchased a robot panda and kept it secret for a long time, but who knew that it met a crazy anchor.
