Zhang Ying seemed to be standing on the podium in the playground.

On the left and right are the school's teachers and leaders, and on the opposite side are more than 3,000 students from the No. 1 Middle School.

She was condescending, holding a pennant in her hand. The eyes of those juniors and sisters were full of worship and regarded her as an idol.

Zhang Ying is no stranger to that podium, she has been on the podium four times or five times at the red flag-raising ceremony on Monday. It's just that in the past, I used to go up and read the review book in front of the whole school.

What kind of fights, bullying other classmates, ignoring school records and other feathers.

If you rank the thorns in No. 1 Middle School, Zhang Ying will not let him take the first place.

If you change to an ordinary student and eat so much review, even if you are not expelled, you will be severely placed on probation.

But Zhang Ying has a provincial championship trophy, and his sports performance deserves to be the first in the school.

Every time she makes a mistake, she has a reason, either to help this boy come out and teach a lesson to a student from another school, or to help that girl teach a lesson to the boy who bullied her.

No matter how reluctant Yizhong is, he can only pinch his nose and plan to continue to endure it for more than a month. Maybe she can mix in a university with her special enrollment status and leave a place for admission to No. 1 Middle School.

Thinking of the wonderful, Zhang Ying laughed on the spot.

Her heroic smile is particularly tasteful, as if the sun outside is shining in.

......

There are many beautiful things.

Zhang Ying is beautiful, but the fruits of Jiang Jiuling's overnight labor are also beautiful.

It turned out that the desk used for writing was moved by Jiang Jiuling to be used as a workbench, and now on the workbench, a metal chassis the size of a shoebox is placed in the middle.

Even without the help of precise measuring tools, the chassis in front of you retains a fairly high level of straightness, with just the right solder joints at the joints, without a hint of superfluity, exuding a mechanical aesthetic.

Some inexperienced people like to use a welding torch around the steel pipe when welding steel pipe structures, and they can't wait to wrap it several times like tape.

As everyone knows, this not only does not play the role of strengthening the structure, but also leads to the heating and bending deformation of the joint, which greatly reduces the bearing capacity of the structure, especially when welding thin-walled parts.

And Jiang Jiuling's works can be used as textbook materials in mechanical professional classes.

After a busy night, Jiang Jiuling has installed all the transmission parts that need to be installed on the chassis, and now he has to start building its power and control system.

In the absence of a circuit test table, decoder and related components, Jiang Jiuling could only give full play to his greatest creative ability to distribute the channel functions of the two remote control modules in his hand and coordinate them together to the greatest extent.

Two remotes, five channels.

Theoretically, all five channels can control a remotely controlled aircraft that requires complex operations.

But the model airplane remote control and the two remote controls in Jiang Jiuling's hand are completely two different things. The former has multiple sets of integrated chips to assist users in coordinating operations, and comes with its own display and custom mixing function.

If you compare the machine tools, the two remote controls in Jiang Jiuling's hands are a lathe and a milling machine.

The five-channel model airplane remote control is a five-axis linkage machining center.

Now Jiang Jiuling wants to merge the two old antique remote controls in his hand into one, which will be used to realize some functions that only the future model aircraft remote control will have.

Or with only one soldering iron.

The remote control should be disassembled and combined into one, and the receiver and steering servo should also be disassembled, and the re-welding circuit should be dismantled, connected to the motor, and its working principle should be changed.

The combined remote control does not have a shell, so use an electric mill to cut the waste wooden box at home and make a new one.

There is no thin copper wire for the corresponding connection, so the line on the red arc chariot is planed, the copper wire is pulled out, and then wrapped with transparent glue.

There are only gears, there is no corresponding straight rack, just use a piece of hardwood to DIY one, and the accuracy is not considered first, as long as it can work.

This electric grinding machine was in Jiang Jiuling's hands, and it almost turned into a machine tool.

As time passed, the work on the workbench also changed shape little by little.

......

Following.

The morning sun of early summer hangs lazily in the sky, and the sun shines on the ground like a layer of silver light.

At the entrance of the campus of No. 1 Middle School, the eight gilt bronze school mottos of "Erudition and Practice, Shengde Rixin" sparkled in the early morning sun.

The school gate of No. 1 Middle School is very large and magnificent.

The whole gate is a [冂] shape, the outside is covered with marble, the gate is a railing structure, and the top is also decorated with wrought iron.

No matter how many middle schools there are, Monday mornings are a regular red flag raising ceremony, so every student is required to wear a school uniform. Now on the road of No. 1 Middle School, students wearing school uniforms and having a vigorous face are walking one after another.

"Stop. ”

"Where's the student ID?" At the school gate, a security officer in military green clothes and several students kept stopping every student who wanted to enter the school gate.

This kind of small card made of a piece of hard paper is easy to lose and wear out after being installed on the body for a long time, so most students are placed in their school bags.

But not all students like to carry school bags, there are always some students who like to be lazy and only bring a few books to school.

Those who showed their student ID cards were released, and those who could not get their student ID cards were detained at the door without exception.

"What are you doing?" a male student who thought he was cool with a pot lid shook his arm and complained to the two students who assisted in the inspection: "Before school on Friday, the teacher didn't inform you that the student ID card would be checked on Monday, and you don't know me, why are you so serious?"

"I know you, but not the Security Section. The student wearing the red armband with the word [check] looked businesslike and refused to be close to him, "Go and wait, you see dozens of people at the door who don't have student IDs." ”

"The sun comes out to kill people, I really don't know what kind of moths the school is doing, I know that it is difficult for students. ”

The boy at the head of the pot was trying to unzip the school uniform to breathe, but his hand suddenly stopped as soon as he put it on the zipper. He suddenly became very nervous and a little overwhelmed.

The two students wearing red armbands also suddenly became nervous, as if a student who was copying homework met the head teacher.

Within their line of sight, a girl wearing light blue school uniform pants and a black half-sleeved sweatshirt walked towards them.

The girls are tall and have clean short hair. The school uniform jacket was casually slung over her shoulders, and her steps were light and with some wanton uninhibited beauty.

At the school gate, all students wear long-sleeved school uniform jackets in a regular manner.

In the light blue figure, she stands out like a black rose.

If youth has a color, then the light blue school uniform she casually puts on her shoulders is the color of youth.

The two students who checked their student IDs cowered and stepped forward, "Eng...... Sister Ying, you bring ...... Did you bring your student ID?"

Zhang Ying, who was empty-handed, didn't speak, but just glanced at them.

"Ah~ Bring it, Sister Ying, go in quickly. The two students were startled and hurried out of the way.
