At night, Yu Ning squatted on the balcony, supporting himself with one hand, holding a fan in his hand, fanning the charcoal fire in the barbecue grill.

The quality of the newly bought smokeless carbon is not very good, it has just been lit, it is still smoking, and as the summer breeze blows in his face, Yu Ning was choked and coughed, and his face was disgraced.

"Mom!"

Yu Liyang ran over with a wet towel and handed it to Yu Ning.

Throwing the pu fan aside, Yu Ning took the wet towel to wipe his face, raised his hand and rubbed Yu Liyang's little head.

"Buzz, buzz. ”

The phone placed on the coffee table in the living room began to vibrate.

Yu Ning wanted to get up, but because he had been squatting for too long, he was a little dizzy and shook a little. Yu Liyang saw it in his eyes, said "I'll get it", and then walked into the house with his little short legs, flipped through the mobile phone and handed it to Yu Ning.

It was a colleague calling.

"Hey. ”

Yu Ning answered the phone, walked to the balcony railing, and looked at the community after nightfall, the lights were sporadic and glowing with warm yellow.

"Sister Yu, I have an interview tomorrow, but there is a bit of an urgent matter at home, and I really can't pull it out, can you help me with the interview?" asked the colleague in a sincere tone.

Yu Ning lowered his eyes and looked at Yu Liyang, the little guy was already squatting in front of the barbecue grill by himself, picking up the pu fan and fanning the wind vigorously.

She pursed her lips.

This month, she ended her vacation early, returned to work, and was busy again. It happened that Yu Liyang had just had a summer vacation, and Yu Ning asked for a hypothetical idea to go out with Yu Liyang, which was a rare opportunity.

“...... Yes. ”

After thinking for a moment, Yu Ning still agreed.

"Thank you. ”

The colleague probably couldn't find anyone anymore, and when he heard Yu Ning agree, he was immediately grateful, and didn't say the place she wanted to interview until the end-

"By the way, it's a drone exhibition organized by Xuanfang Technology, and I sent you the address. In addition, the interview is only half an hour in total, if Xiaoyang likes drones, Sister Yu, you can also bring Xiaoyang over without delay. ”

“......”

Yu Ning was stunned.

Holding his mobile phone in his hand, Yu Ning raised his eyes to look at the night sky, the stars were dense, and it was a rare good weather. There was a night breeze blowing, slightly hot, with the smell of summer.

"Mom?"

Yu Liyang turned sideways, raised his head, blinked his eyes, and called out to Yu Ning strangely.

"Xiao Yang," Yu Ning squatted down, lowered his head slightly, flicked his fingers on Yu Liyang's forehead, curled his lips and smiled, "Mom has a temporary job-"

Yu Liyang's shining eyes gradually dimmed.

Suddenly, Yu Ning's words changed, "How about taking you to see the drone exhibition tomorrow?"

"Good!"

His eyes lit up, and Yu Liyang nodded without thinking. Try to pretend to be calm little cool brother, and there is joy that can't be hidden at the moment.

Yu Ning bent his lips, pinched Yu Liyang's little face, and smoothed the pu fan in his hand, "You go and urge Lao Yu, when will you come back, barbecue mother will get it." ”

"Hmm. ”

Yu Liyang nodded and obediently ran back to the living room.

*

The influence of Xuanfang Technology is growing, and all models and types of drones are displayed at this exhibition, including the new ones they have not yet launched, which has attracted a large number of enthusiasts.

In addition, because Ling Xize controls Kulan Video, Kulan Video has signed a group of up masters, many of whom have millions of high-achieving students, so there is a live broadcast specifically responsible for showing the exhibition process, and the live broadcast host invited several up masters to serve, one is to increase popular science education, and the other is to increase the popularity of the exhibition.

As for the regular media, they generally come for the half-hour interview with Yan Tianjing of Xuanfang Technology.

......

"Brother Rebellion, Brother Mian, Xiao Yang will ask you first. ”

Arriving at the entrance of the exhibition venue, Yu Ning handed over Yu Liyang to the two. She was dressed in a formal suit, put on some makeup, and was refreshed, without the haggard appearance of last month.

I wanted to let Yu Liyang stay in the store outside during the interview, but I didn't expect that when I mentioned it to Yu Tianqin at night, Yu Tianqin said that Xiao Wei would also go over and could be handed over directly to Xiao Wei.

- Anyway, it hasn't been a day or two since Xiao Wei took Yu Liyang.

As soon as Yu Ning asked, if this was the case, he made an appointment with the two of them in advance.

"Hmm. ”

Xiao Yi took Yu Liyang and nodded.

Yu Liyang raised his head and said soothingly, "Mom, don't worry." ”

Yu Ning smiled.

Si Fengmian was a little depressed, why is this sister Xiao Shun here as "elder brother", and here he is "younger brother", he doesn't seem to be as reliable as Xiao Shun?

After making a phone call with the colleague in charge of photography, Yu Ning smiled, said goodbye to the three of them, and walked into the exhibition first.

"Xiao Wei. ”

Yu Liyang grabbed Xiao Wei's hand, pulled it lightly, and lowered his voice to talk to Xiao Wei.

Xiao Zhihu glanced at him suspiciously, and then leaned down slightly and listened to Yu Liyang's words.

"Sister Si, is it better for you to get the first place in the exam because of you?" Yu Liyang asked seriously.

Xiao Wei: ?

After a pause, Yu Liyang said again: "I heard that Si Fengmian took the test. ”

This is a great opportunity!

On the other side, Si Fengmian, who saw the sneaky appearance of the two, took the initiative to come over, and just heard Yu Liyang's words, he couldn't cry or laugh, "Yangyang, is your heart too obvious?"

“......”

Yu Liyang paused, glanced at Si Fengmian, and then took half a step back.

Pulling Yu Liyang back slightly, Xiao Wei calmly looked at his boss Fengmian's gaze, and said softly: "He likes good grades." ”

“......”

The corners of Si Fengmian's mouth twitched slightly.

! You score zero, this kid is still firmly on your side!

Fortunately, Si Fengmian is a good temper, and after being depressed for a while, he turned the page on this matter, and encountered a small game of playing games to win candy, and he took a lot of effort to win a few candies, and handed them to Yu Liyang to eat after he came back.

Yu Liyang ate two, divided two of them, and put the rest in Xiao Wei's pocket and asked Xiao Wei to take them back for Si Sheng to eat.

Xiao Wei saw that he was so active in having a good relationship with Si Sheng, and did not tell him that Si Sheng might not be able to return to the crew today.

......

At ten o'clock, the process reached the first item.

At that time, Xiao Wei, Yu Liyang, and Si Fengmian had just lined up to play a game, and suddenly heard a burst of cheers, and when they looked up, they saw dozens of drones hovering in the air, not a few common colors on the market, but specially changed the festive shell, and in a blink of an eye, the words "Xuanfang Technology" were discharged in the air.

Immediately, the fireworks were exploded.

Immediately afterwards, the drone was combined into various words, and there were color changes around the body, which were varied and dazzling.

Until the end, there was a long queue, and one banner after another fell from the walk to the right, all of which were all blessings sent by fans.

Very good show.

During the five-minute performance, more and more people gathered around, and on the makeshift stage, there were staff members who acted as hosts to give a short introduction to each drone in the sky.

Behind him, their details flashed on the screen.

"Finally, I would like to introduce you to a unique drone - the mechanism drone. It is the crystallization of great wisdom by combining advanced technology and ancient mechanical techniques......"

Moderator: Let's go, let's go.

Si Fengmian knocked Xiao Wei's arm, raised his head, and looked at the drone flying in from the gate, his eyes were so familiar that he was shocked.

"Sister and brother-in-law, one of the hundred and eight ways to show affection?" Si Fengmian was shocked.

“......”

Xiao Wei was speechless.

- These two are really good at playing.

However, in less than three seconds of complaining, the attention of the two - and even the attention of the audience - was attracted by the display of the mechanism of the drone.

There is no need for manual operation, under the automatic operation of the system, through the large screen behind him, the people present and the live audience can show the mechanism of the drone in real time.

The display of the two forms, with a pair of long couplets hanging down on the left and right, ends with a flower falling in the middle after stabilizing.

And what shocked the people present was the automatic display of the operation of the mechanism-

The use of modern technology to achieve this level, everyone applauded at most, but the large screen clearly shows the structure of the mechanism, the composition of this drone is made of wood, and the display of the operation model of the mechanism is even more dazzling.

None of the high-tech talents present could understand it.

Live barrage:

What are ??? playing?】

[Tricks are on fire!]

[I actually saw a thousand-year-old trick in the science and technology exhibition? No, how does this horse operate?]

[, Xuanfang Technology is awesome!Who is this looking for to design?!]

......

Originally, there were not many barrages of live broadcasts, but they were instantly occupied by barrages, densely packed.

in the crowd.

Xiao Zhi's eyes flashed, and after a while, he squeezed out a word very indifferently, "Serve." ”

"Sister is a real cow. ”

Si Fengmian's eyebrows fluttered, and he sighed sincerely.

"But," after a pause, Xiao Wei turned his head, twisted his eyebrows slightly, and asked abruptly, "What's the meaning?"

Si Fengmian: "......" is probably very showy.

------Off topic------

【1】

This chapter is broadcast live.,The reference is station B.,Station B was held a few times last year.,I also cooperated with the Institute of Physics of the Chinese Academy of Sciences.。 My fan's up master participates in such a science and technology exhibition...... He's obviously a game master.

In addition, "Mechacl" refers to "This is Iron Armor".

What I didn't say, there was no prototype. For example, "Escape Room" really has nothing to do with your "Ming Detective". is "City Secret", which is substituted for "Extreme Challenge".

I had a cold and was not in the state.

It's been a long time since I've pushed a song.

Wu Bai's "Last Dance", take a look.
