Seeing her staring at her, Zhang Nian said in confusion: "What's wrong, Sister Dong?"

Jin Dong'er's eyes paused for a moment, and she said, "Xiao Nian, I found that your breasts and breasts seem to be bigger than before, so you have to have a b."

After taking a shower, I went to my good sister's room. Her room was right next to me. Naturally, I didn't care. I put on a wide nightgown, which was empty and her breasts were very soft. In fact, she was very soft and swaying with her movements.

Zhang Nian was embarrassed: "Sister Dong will laugh at me, you are so old."

After saying that, he ran away.

Jin Dong'er lifted her skirt and looked at it. She was still not satisfied. She reached out and touched her hands twice, and said, "Well, I am indeed bigger and broad-minded."

The interview the next day was still scheduled in the afternoon. Liu Chen had a habit of getting up in the morning and thinking became divergent. He prefers freedom and does not want to arrange standardized things.

However, he still came to Jiangning West Roadba E-commerce Headquarters. Cao Rong saw him coming and smiled and said, "I didn't go back to sleep yesterday. I was working on the floor in a room next to the laboratory. Now I'm working again."

“That’s so enthusiastic about work?”

"Yes, I don't dare to be lazy when I see them fighting like this."

Liu Chen thought for a while and said, "Now the fourth and fifth floors are empty now. You might as well convert them into dormitories. No one has a relatively independent space. Passion is good, and it is difficult to last if you don't control the rhythm well. Just use partition cabinets and soundproof cotton. It's fast and there's no pollution yet."

"Okay, I'll do it right away."

Fang Zhigao hurried over, with a sense of joy all over his body. When he saw Liu Chen, he hurriedly said, "Mr. Liu, I'm about to look for you."

"That's good, all enthusiasm has been mobilized."

"Haha, probably every Jiangda engineering man has the potential of geek. We held a meeting last night and unanimously decided to develop a model aircraft first. First, we will work together the team division of labor, and second, we will make up for the shortcomings. Jiangda still has a distance here. Can we solve the accommodation problem?"

"I thought of going together. I have asked Cao Rong to renovate the third and fourth floors and move in tonight. However, I think this place is still too noisy. In the long run, it may not be conducive to R&D. Recently, I will start looking for places around the surrounding area." Liu Chen said that Jianghai land is already very expensive now, and it is not realistic to establish a super logistics center. It is best to obtain land from nearby. Kuncheng is a good choice. It is close to Jianghai, and its development is just beginning.

"There's another thing." Fang Zhigao scratched his head, "I accidentally told you out. Several little kids were clamoring to see you. What do you think of this?"

Liu Chen didn't want others to question anything about his age, and he couldn't prove it to everyone. After six months of going to the United States, he deeply felt one thing. Americans generally agreed that geniuses were unique when they were young, so it was taken for granted to young people.

There is a saying in China that you have no worries and can’t do things well. Young people are always considered to be frivolous and difficult to do things. This obviously applies in official politics.

But in the ever-changing technology world, super gods are often young people, with high energy and no fatigue when working for 20 hours a day. They accept new things quickly, have strong brain vitality and amazing efficiency. The most important thing is to be able to focus and have a strong desire to transform the world.

"Then go and have a look, Xiao Qian is there too, right?"

"Here, this kid is very skilled and is very sensitive to algorithms. He is the first to solve several small problems. All the top students from Jiangda are very convinced."

Liu Chen and Fang Zhigao came to the laboratory on the third floor together.

There is a heated discussion inside.

"The calculation of rotor aerodynamic parameters is very complicated, and the results require high sensor accuracy and poor environmental adaptability."

"Mechanical modeling can reduce the calculation amount of parameter identification, and parameter identification can further improve the accuracy of the model."

"Using the iris theory to analyze the lift and torque of the rotor, using aerodynamics and Newton-Euler equations to establish a dynamic model of the platform mechanism, and then using identification tools to identify qigong parameters with large uncertainties."

Liu Chen saw two *************** on the middle table, a model built with wire racks, and a motor and rotor were fixed on the four corners. Fang Zhigao said: "The structure is built by Guo Liang, the motor is a stepper motor, and the driver is ready-made by me."

When everyone saw Fang Zhigao coming, they all shouted respectfully.

"The head of the house."

"Brother Fang."

"Boss."

Obviously, Fang Zhigao's technical strength is enough to convince the public.

"Who is this?" muttered in his heart and discussed a few words softly.

Obviously, they had never seen Liu Chen.

He Qian walked over happily and said, "Brother, you are here. We are making a small plane. It's very fun."

There are many different opinions.

Shi Sen also looked over curiously.

Fang Zhigao introduced grandly: "This is our Mr. Liu, whose technical and scientific research achievements are unfathomable."

"No." Li Lin couldn't help blurting out.

Sure enough, everyone showed an incredible look when they saw Liu Chen so young.

Accustomed to it, Liu Chen ignored it and asked Fang Zhigao: "Can the four-rotor fly?"

He blushed and said, "It's not OK yet. It's very complicated. It involves the control strategies of the four motors, the remote control and communications between them."

"It's not that complicated. Let's fly first." Liu Chen had a faint smile on the corner of his mouth. He measured the weight of the small plane. Seeing that there was still some space on the whiteboard, he recorded it, started the power, and the four stepper motors rotated, constantly increasing the power until the entire plane trembled and was in a critical state. Use a multimeter to measure the voltage and current values.

Everyone stopped to look at his actions. During the interview, everyone knew that an interviewer had a very toxic mouth. When he was nagging, Fang Zhigao laughed and said, "That's not me, it's all asked by our Mr. Liu."

Everyone was holding their breath.

Seeing that the person who asked me so young, I felt even more dissatisfied and deeply suspicious.

Liu Chen naturally knew what they thought, so he ignored it. Then he drew a block diagram of typical pid control on the whiteboard, calculated the parameters based on several measured quantities, and then turned to ask Fang Zhigao: "Control chips are 51?"

"Well, there are too many pins of dsp, ds, plc, and the peripheral circuit is complex. There are very few peripheral circuits of 51 chips. They can directly drive the stepper motor. The weight is very light, otherwise the power of such a small stepper motor is not enough." Fang Zhigao said as he turned on the 51 development environment on the computer.

Everyone looked at it curiously and thought to themselves, will it be successful? Don’t shoot yourself in the foot.
