country made

If it is possible, Ji Yu would rather Xiao Song do those things to him like in the past, and he doesn't want him to be as restrained as he is now.

Because obviously brother Song has already noticed that this is not something that should be done between "brothers".

Ji Chen wondered if Xiao Song's sudden depression was because he knew what "gay" was, but it didn't feel like it, because Xiao Song recovered after only two or three days of elimination.Ji Chen felt that even in a relatively open environment in the future, no one would accept so quickly when they found out that they were gay, let alone in this era when homosexuality was still judged as a mental illness.

But he didn't dare to ask, he was afraid that Brother Song didn't know, what if he accidentally understood it?

But what is certain is that Xiao Song's feelings for him are different.

More cherished, more pampered, and more... affectionate.

This made Ji Yu, who had never had any emotional experience, at a loss as to how to respond.

It's easy to accept, since I've done more intimate things, is there still a relationship?

But just because he valued little brother Song, Ji Chen didn't dare to think about it.

In his opinion, brothers and friends can be together for a lifetime, but lovers may break up. Although he has no experience in love, he has seen the separation and reunion of friends around him countless times. He has never seen anyone who can go from first love to marriage. .

Ji Yu can't imagine that he and Song Jining will be strangers one day, so no matter what kind of feelings Song Jining has for him, he will not accept it.

Fortunately, Song Jining never said it, so Ji Yu continued to pretend that he didn't understand anything. Recently, he tried to cool down Song Jining's feelings by taking advantage of his busy experiments.

But it seems to have little effect.

The two buried their heads in cleaning the dust from the window sills and the floor. Song Jining looked at the warehouse machines in the room and asked Ji Yu, "Do you need to clean these machines?"

Ji Yu looked at his watch: "It's too much, anyway, there are still more than ten days, wipe it slowly! But..." Ji Yu raised his head, walked to the high-shear homogenizer again, stroked the fuselage, his eyes Searing: "We can clean this machine first."

There is no dust on the body of the high-shear homogenizer. Obviously, it was not long after it was put in. After powering it on, Ji Ruan found that the equipment could not operate and the machine was broken. No wonder it was put in the warehouse.

"It's a pity..." Ji Yu used the third-generation high-shear homogenizer at the beginning. He only saw the first generation in the data map. It is said that he bought a batch of hundreds of machines from the Soviet Union back then. , used for nearly ten years, and later improved by domestic researchers to produce the second and third generations, which became popular in China.Its role in domestic industrial production is not inferior to the eight-axis CNC machine tool developed by the teacher.

Thinking of this, Ji Yu suddenly turned to Song Jining.

For the past few years, he has only been focusing on getting Xiao Song to study for college, and almost forgot the most important thing, the eight-axis CNC machine tool!

When the teacher developed the eight-axis CNC machine tool, Ji Yu was in college and did not participate.It was only later that I heard that the reason why he developed CNC machine tools was that Huaguo and other countries had already reached a contract to purchase high-end machinery including high-precision CNC machine tools, but was destroyed by the US emperor. Later, the teacher was so angry that he pulled up a team. Carried out research, after two years of research, it actually succeeded.

Later, the teacher also entered the Chinese Academy of Sciences based on this achievement and established his own research institute. After graduating from University, Ji Yu became his student.

However, if the teacher was not from the military department, most people would not have the inside information about such things as being broken by the United States.So Song Jining, who has never joined the army, seems to have no chance to know about this, so he will not delve into eight-axis CNC machine tools because of this?

Although he can also lead Song Jining to study, Ji Yu himself has never studied it. His main research direction is not CNC machine tools!

After Song Jining twisted a few buttons and there was no response, he tapped on the fuselage and said, "It can't be started, Yuanyuan, let's go back..."

He turned his head, only to see Ji Yu looking at him with complicated eyes.

This kind of look, when he wanted to drop out of junior high school, when he just started to learn electronic machinery, Ji Yu once looked at him like this.

Like guilt, like disappointment, like worry, Song Jining couldn't understand the complexity of it.He was a little bastard at the time, he felt he could understand how Ji Zhuan looked at him!But isn't he fine now? Why does Ji Zhuo think of him like this?

"Yuanyuan, why do you look at me like that, is there something wrong with me?"

Ji Yu held Song Jining's hand: "I'm sorry little Brother Song, I shouldn't just focus on myself."

"what?"

"Starting from this high-shear homogenizer, let's work hard together!"

"what?"

Ji Yu temporarily put down the research on the electric explosion foil detonation system. After all, this research is not in a hurry, it is just for the needs of future papers, and delaying it for half a month has no effect.Conjugate plate hot indium pressure sealing high shear homogenizers are not always available, and the teacher will not let them in after the labor period.

Fortunately, this high-shear homogenizer has broken down, and there is no psychological burden for Ji rafters to disassemble.So when they come to the warehouse these days, they will spend half of the time cleaning and wiping other machines, and then the other half of the time will be dismantling the Conjugate Disk Heat Indium Compression Sealing High Shear Homogenizer.

As high-precision machinery, high-shear homogenizers and CNC machine tools have some systems and functions in common, such as the hierarchical structure of hydraulic flow resistance and the pressure and flow of the electromagnetic proportional relief valve adjustment system. After understanding, you will find The basic design ideas are common.

Ji Zhuan used and maintained the third generation, but he didn't have the opportunity to disassemble the whole machine at that time, after all, the equipment is very expensive.Therefore, he was actually very excited to be able to disassemble the first generation and thoroughly understand this high-precision machine.

Song Jining was in a daze from beginning to end.

He didn't know this machine, and he didn't say that he wanted to learn it. For some reason, Ji Chen just thought he should know it and understand it.But since Ji Yu liked it, Song Jining cooperated with him in studying.

Who told him to like Ji rafter, he wanted to do things that would make Ji rafter happy.

One is to teach Xiao Song, and the other is self-study. While dismantling the high-shear homogenizer, Ji Zhen redraws its construction diagram.Every time a part is disassembled, draw a part, and deduce the design structure, calculation method, etc. according to their lines.

Poor Song Jining, who managed to keep up with the research on the electric explosive foil detonation system, was thrown out of the sky again soon.

The ghost knows how the hierarchical structure of the conjugate disk is designed!

The ghost knows how the fluid hydraulic pressure of the hot indium press seal is calculated!

Why did he not understand what Ji Chen said at all!

But as a man, how could Song Jining say "I'm not interested" and "I don't understand" in front of the person he likes, facing his shining eyes!

Not to mention the question of whether the two men can talk to each other, if the IQ gap is too large, and there is no common topic, I am afraid that they will not even have the opportunity to study together every day.

This is a university of science and technology, and there are many people who can talk about mechanical principles with Ji Yu.

For the sake of face, the focus is on Ji Yu. Even if he doesn't know anything about this equipment and has no interest, Song Jining still puts out 12 points of studious spirit, accepts Ji Yu's guidance every day, and writes a thick book full of notes .

Every time he thought he was on the same level as Ji Yu, Song Jining found himself far away from him.

For example, this Conjugate Disk Hot Indium Compression Sealing High Shear Homogenizer, he didn’t know where Ji Yu knew about this instrument, and where he learned about it, when he discovered that what Ji Yu taught actually included statics , Song Jining refrained from asking him when he had learned static dynamics.

He used to think that Ji Yu was different from ordinary children, and he used to think that he was good at reading, but now what he knew and learned could not be explained by "good at reading".We are together every day, and he has read all the books that Ji Chen has read, but he has never seen relevant content in books, whether it is the electric explosion foil initiation system or the conjugate disc hot indium pressure sealing high shear homogenizer .

Where did Ji Chen's knowledge come from?

Ji Yu didn't know that Song Jining had become suspicious of him, and it had been ten days since they disassembled the entire Conjugate Plate Hot Indium Compression Sealing High Shear Homogenizer, although they still couldn't fully understand its design Principle, but at least Ji Rafter already knew where it was broken.When it was reassembled, Ji Yu repaired it by the way, and he kept a hand, he only repaired half of it, and he would deliberately pretend that he couldn't do the other half and leave it to Song Jining to solve.

"Brother Song, what should I do with the composite steel pole here, it seems to be stuck?" Ji Yu tilted his head and asked Song Jining.

Song Jining has helped Ji Yu solve several problems in this way, at first he really thought that Ji Yu was asking him for help, Song Jining was happy, and when he returned home, he secretly read books until midnight.As a result, after many times, no matter how stupid Song Jining was, he knew that Ji Yu was teaching him in another way.

I want to choke up my blood, but thinking of Ji Zhuan's character of not lying, teaching him clumsily in such a clumsy way, I think it's so cute.

Then Song Jining, who received Ji Zhuan's request for help for the third time today, smiled.

He leaned down and stretched his arms, trapping Ji Rafter between himself and the equipment.

"Are you asking me for help, Yuanyuan?"

Ji Yu squatted on the ground and nodded, somehow feeling a little stressed, Xiao Song was too close.

Song Jining looked at Ji Yu from top to bottom, narrowing his eyes: "If you want to ask me for help, shouldn't you show something?"

express?

Ji Yu was puzzled, what did he mean?

"Well, do you want maintenance fees?"

Song Jining smiled.

angry.

He stretched out his fingers and wiped Ji Yu's face: "It's stained with engine oil." Before Ji Yu could respond, he raised his chin with his hand and put his lips together.

As Song Jining grows older, Song Jining's desire becomes stronger and stronger. He used to do it often enough with Ji Yu, not to mention that he has been reluctant to do it now, and he almost hardened when he tasted Ji Yu's soft lips.

"Mmm... woo..."

Ji Yu hadn't been kissed so intensely for a long time. He was pressed against the hard equipment, and his lips and tongue were sucked hard. Through the passionate kiss, he clearly felt Song Jining's suppressed desire.

After a long time, when Ji Yu was almost out of breath, Song Jining let him go.

Holding Ji Yu, who was short of breath, in his arms, patted his back to comfort him, Song Jining chuckled: "This is the reward I want, as long as you give me this, I can do whatever Yuanyuan asks me to do."

Where did Ji Yu know that knowledge, whether he has any special background, why he must pull himself, must teach himself, Song Jining thinks it doesn't matter.As long as he can hug and kiss Ji Rong like now, he will be satisfied.

It would be even better if one day, Ji rafter could accept his love, although judging from the current situation, maybe as long as he said it, Ji rafter would be able to accept it.

But he didn't want to drag Ji Yuan into the vortex of "mental illness" before he was able to protect Ji Yuan.

Ji Yu leaned against Song Jining's chest and breathed hard, and hit him when he heard the words: "You...you obviously kiss every day..."

Yes, although he didn't do it again, Song Jining's kisses were not less every day, on the contrary, they became more and more. When he was at home, he often kissed him every now and then.Fortunately, the two of them have slept in separate rooms now, and after Ji Yu hid in the room, Song Jining had nothing to do, otherwise he thought that Song Jining might kiss and kiss, so he followed the trend.

Song Jining raised the corner of his mouth and kissed Ji Yu on the top of his head: "Okay, I'll fix it for you now."

He just wanted to bully Ji Zhuan who lied to him.

Of course, she also simply wanted to kiss Ji Rafter.

The two spent ten days dismantling the conjugate disc hot indium press-seal high-shear homogenizer,

The author has something to say:

It took five days to reinstall it.Although the time is too short to fully understand its design principles and core, but the basic design structure and assembly and maintenance, it is almost understood, and then I only have to go back and digest it myself.

But when they returned the keys and went back to report to the teacher in charge, Lin Binliang asked suspiciously: "Hey, are you still cleaning the warehouse? Didn't I say a few days ago that I don't need you to clean it?"

Because Ji Yu and Song Jining were cleaning the warehouse very seriously, after Lin Binliang went to check it once, he felt that they had a good attitude of introspection, so they were exempted from labor punishment.At that time, though, the two were obsessed with the high-shear homogenizer, running past school as soon as it was over, not paying attention.

Ji Yu didn't think it mattered, although he had done a few more days of labor, but he also learned what he wanted to know, which was very cost-effective for him.

Song Jining couldn't help but want to knock himself on the head, because he found that he hadn't noticed such an important word "no need to work".Looking back on those few days, apart from Ji Zhuan, he only had various knowledge of machinery, structural design, and statics in his mind, and he didn't listen to other words.
