a quarter of his

After agreeing to play drones with Xu Chen, Lin Jingfan was in a state of excitement for several days, wishing he could come on the weekend.

The two made an appointment on Saturday morning, in the big playground of the old campus. Even though Xu Chen repeatedly emphasized to him not to go so early, he still went out as soon as nine o'clock arrived.

As poor as he is, this is the first time he has the opportunity to meet the legendary DJI.

Lin Jingfan's understanding of DJI began in this year's primary semester. One of the college's practical training programs is small aircraft, and he just chose that direction.

At that time, the instructor invited was an executive working in DJI. In the first class, he proudly introduced the origin and achievements of DJI to everyone.

Lin Jingfan still remembers it very clearly. The course that day started with a video of a rock singer who had never been on the hot search to a certain domestic three-time Grand Slam actress. Then he talked about the origin and development of DJI, and talked about it. Speaking of the various achievements created by DJI, it is said that DJI is used by Hollywood as an aerial photography machine...

When they saw the silver-white quadrotor drone gracefully passing by the blue sea and blue sky in the video, the passion of a group of teenagers was instantly ignited.

Lin Jingfan couldn't control his excitement, just when everyone was full of expectations and thought that he would make an equally awesome drone, he smiled evilly and sent out the training materials.

A group of people stopped eating immediately——

Packed in a plastic bag is a bare single-chip microcomputer the size of a palm, and six plastic propellers the size of little fingers.

Lin Jingfan: ...

The teacher picked up the prototype, looked at everyone seriously, and introduced: "Students, what you are holding in your hand is the six-rotor aircraft we will make this semester. Everyone install the rotor on the small aircraft and install the battery. Now go outside on the lawn to test the flight..."

All black question marks: Is this also called a drone?

Every time Lin Jingfan recalls this scene, he finds it very funny, and he can't help but lament how ignorant he was at the time. That little flying machine almost drove them crazy this summer, and he never dared to think about "making "It's about a DJI.

He thought a lot of messy things, and when he came back to his senses, the playground had already arrived.

There were no people in the playground on weekends, especially in the morning, as soon as Lin Jingfan entered the playground, he saw Cheng Long's drone at a glance.

It was a gray-black four-rotor drone, which was lying quietly in the middle of the lawn of the playground at the moment, looking like a black arthropod monster from a distance.

Lin Jingfan glanced around, and soon found Xu Chen who was leaning against a tree to adjust the remote control.

He was wearing a gray sweater and sweatpants today. His yellowish hair had just been washed, and it was a little frizzy, but it was a little more smokey than usual.

"Brother came so early", Lin Jingfan went up to say hello.

"I woke up and couldn't fall asleep, so I came here early." Xu Chen rubbed his hair with a smile, and handed him the remote control, "Try it? I just flew once."

"Ah... I'm coming?" Lin Jingfan took the remote control and immediately became nervous, "I haven't used it before, so it won't break."

"It's so easy to break." Xu Chen was amused by his nervous appearance, "With me here, what are you afraid of?"

Lin Jingfan smiled: "The main reason is that the summer vacation was overshadowed by our small aircraft."

"Engineering training?" Xu Chen adjusted the dial of the remote control, asked Lin Jingfan to rest his hands on the dial, and taught him how to operate it.

"Yes, this year's summer vacation," Lin Jingfan said, "Our aircraft almost lost contact on the first day of the test flight, and it kept flying into the sky, flying out of the control range of the remote control, and kept flying up. , until it becomes a dot, and in the end you can’t see it at all.”

"Hahaha", Xu Chen smiled understandingly, "How did you find it in the end?"

"The battery is out," Lin Jingfan said helplessly, "I fell down. At that time, the sky was full of aircraft, and I only heard a loud 'plop'..."

"Broken to pieces?"

"No, fortunately, half of my life was spared," Lin Jingfan said, "But all six propellers are broken, brother, did you make a small car or an aircraft?"

"Neither of them." Xu Chen met Lin Jingfan's puzzled gaze and explained, "We had three choices back then, one was to make smart cars, the other was to make aircrafts, and the other was to make ships."

"Build a boat?" Lin Jingfan opened his eyes wide in disbelief, "So handsome?"

"That's right," Xu Chen said, "At that time, it was a trial project. Only 500 of the [-] people in the whole college could enter the boat building project. The college borrowed a swimming pool from the school. So that summer, we often saw us Jump into the pool with your clothes on to save the boat."

"It's fun."

"There's something more interesting," Xu Chen said, "In the end, because there were too many 'wet bodies' in a day, everyone ended up wearing swimsuits for experiments."

"Pfft", Lin Jingfan really couldn't imagine the picture of a group of people wearing swimsuits sitting by the swimming pool debugging the code, it was really eye-catching and very interesting.

Xu Chen said, "Next time I will show you the photos we took at that time."

"Okay, so senior brother, why didn't you keep this project in the end?"

"I don't know," Xu Chen said, "I heard that it was complained by other colleges, saying that we occupied the swimming pool in elementary school, making it impossible for students from other colleges to swim."

The two of them were having fun at the same time, "hahaha" laughed for a long time, and when they mentioned the funny things during the training, they really felt that they couldn't finish the chat.

Lin Jingfan pushed the dial of the remote control forward, and the aircraft made a "humming" sound and slowly rose from the lawn.

"Yes, that's it, don't be nervous," Xu Chen's voice came from the side, "The dial on the right controls the front, rear, left, and right, first let the plane fly within the playground..."

Lin Jingfan operated according to Xu Chen's instructions. At first he was a little nervous, but his mind was highly concentrated. Xu Chen kept watching from the side and reminded him of some operations from time to time.After he got familiar with it, he leaned against a tree and let him play by himself.

Lin Jingfan controlled the plane's ascent and descent, and pushed the lever to the left. The aircraft flipped in a circle in the air, and then took off again.

"Damn! This is too handsome!" Lin Jingfan turned his head excitedly, and was about to share the joy of this moment with Xu Chen, but found that Xu Chen who was leaning on the side was also looking at him with a smile.

And, it seems that he has been looking at him like this for a long time.

Suddenly, a strange feeling flooded into his brain.

Could Xu Chen be gay too?

Did he see him?

Although Lin Jingfan is usually narcissistic occasionally, he is not so big emotionally.

However, he has been vacant for more than a year, and has been busy studying, and it seems that he is not very good at dating.

Don't think too much, it will be embarrassing if you are narcissistic, Lin Jingfan couldn't help saying to himself, but his brain kept thinking about things uncontrollably.

The scenes of getting along with Xu Chen flooded into his mind one after another. To his surprise, the two of them actually didn't have much contact with each other since they met, but it seemed like they had known each other for a long time.

"Be careful! Fly to the right! Right!" Just when Lin Jingfan was distracted, Xu Chen's nervous voice suddenly came from behind.

Lin Jingfan's heart tightened, and he was about to look up to the sky when his hands were suddenly covered with warmth.

Xu Chen's hands were stacked on top of his hands holding the lever, leading him to control the aircraft.

Under his control, the aircraft seemed to have life. At a wonderful angle, it slanted sideways and flew into the open sky.

It was only at this moment that Lin Jingfan realized that the aircraft almost crashed into a tree when his mind was distracted just now, and he couldn't help but feel scared for a while.

"I'm sorry, senior brother, I just..." Lin Jingfan was so guilty that he couldn't add more guilt, "Fortunately you are here, otherwise I would have to apologize to Cheng Long tonight."

What made Lin Jingfan afraid was nothing else, but that the aircraft itself did not belong to Xu Chen, if it was damaged by him.Even if there is a little problem, it will bring unnecessary trouble to Xu Chen.

"It's so serious." Xu Chen maneuvered the aircraft in a circle gracefully, "If I dare to hand over the remote control to you, I will guarantee the safety of the drone. Come, let you see the technology of my brother."

After finishing speaking, he controlled Lin Jingfan's left hand to move forward, and the plane accelerated into the air, and then swooped down under Xu Chen's control.

Xu Chen manipulated his hands flexibly, and every movement seemed to be precisely calculated.The fuselage of the aircraft flipped rapidly at high speed, and when it was about to fall to the ground, it soared into the air again, brushing the tree that Lin Jingfan just hit and flying away, bringing a gust of wind.

"You are too awesome, brother." Lin Jingfan expressed his sincere admiration.

"It's okay." Xu Chen said "tsk" and said, "I didn't wear glasses today. If I wear glasses to watch the aerial pictures, it will be more exciting."

The two of them maintained this movement until Xu Chen gently dropped the drone back to the ground, and Lin Jingfan suddenly remembered something.

"Brother, didn't you say that you are going to measure the data today, why..." He turned his head, and before he finished speaking, he was stunned.

He was too focused on playing just now, and only now did he realize how ambiguous the posture between him and Xu Chen is now.

Xu Chen almost wrapped his whole body around him from behind, guiding him to control the remote control.

Lin Jingfan was dying of embarrassment, but Xu Chen let him go naturally as if he didn't notice anything wrong.

"The test hasn't started yet," Xu Chen took the remote control from his hand, "Let's start now."

"Oh, good," Lin Jingfan said, "Do you need my help? You are the only one in your team?"

"This is not the subject of our team." Xu Chen readjusted the remote control and lifted the drone into the air. This time, he no longer showed off his skills as before, but started aerial photography according to a certain trajectory.

"It's a team of undergraduates led by Mr. Cheng Long. They are going to make an unmanned driving system and plan to use our campus for experiments. They need an aerial map and data of the campus."

Although Lin Jingfan's direction is artificial intelligence, he also has a simple understanding of unmanned driving, and the two began to discuss some professional matters.

Xu Chen knew a lot, and Lin Jingfan felt that if he gave himself another three years, it would be impossible to reach his level.

To his surprise, Xu Chen at work was completely different from his usual easy-going appearance, very serious and strict.

The two took turns filming for two hours before finally reaching his standard.

I remembered that when Xu Chen shared with them a year ago, Cheng Long forcibly summoned him back who was an intern at Tencent, and bluntly said that the project would not work without him.At that time, he only thought it was an interesting story, but now he really understands the meaning behind it.

It was a little faster to finish the task, and the two went to the cafeteria to have a meal.

After a morning of serious work, the embarrassment caused by intimate contact in the morning has completely disappeared.

While eating, Lin Jingfan looked at Xu Chen who was sitting opposite, and thought that he might really be thinking too much.

It's normal for boys to have occasional physical contact, let alone an emergency at that time.

He also felt that he was a little too sensitive, he couldn't meet everyone and think he was gay.

Having figured this out, he felt a lot more at ease.

Just think of Xu Chen as a good friend who can talk to and is awesome.
