From scrap mecha to science fiction paradise

Chapter 3 Purchasing Hydraulic Oil
"Hey, isn't this Brother Lin? He's here again. Are you going to take care of the old man's business today?"

They came to a scrap station again. The old shop owner, who was lying on his back on a recliner, drinking tea and basking in the sun, immediately became energetic when he saw Lin Yu coming in. His wrinkled old face smiled like a chrysanthemum.

"Then it depends on Mr. Zhang whether you have anything I can use."

Lin Yu expressed his gratitude to the old man for his enthusiasm.

This old man's junkyard is the one he has visited the least.

Without him, this old man has a sharp eye and can't catch anything.

But precisely because of this, Old Man Zhang has the most good things here.

He had reluctantly bought several important accessories here before, which was why Old Man Zhang was so enthusiastic about seeing him.

"Hahaha, just take your pick and I'll give you a fair price if you find it right."

Old man Zhang also laughed after hearing Lin Yu's words.

"Come to Mr. Zhang, who in a place like you wants fair prices? You should give me a cheap price."

Lin Yu replied angrily, and without any politeness, he started rummaging through the garbage dump where all kinds of used parts and equipment were piled up.

The bulk of the income of a waste picker recycling station like this is from the various conventional recyclable materials that are picked out and directly sold in batches to various processing and recycling channels. The remaining unsaleable items are thrown here and randomly selected, and quotations are made on the spot.

After a rough scan, I found that since Old Man Zhang has a good eye for receiving goods, there are still good things here.

Unfortunately, all he needs now is No. 5 heavy hydraulic oil.

"Ok?"

After rummaging through piles of electronic waste for nearly half an hour, Lin Yu's eyes suddenly lit up.

That’s a tiny supercomputer the size of a wardrobe!

In the age of intelligence, computers are the soul and productivity. Even the smallest supercomputer is worth a lot of money. You can tell with your head that this thing is just an empty shell.

However, due to power issues, the operation of supercomputers will generate extremely large amounts of heat, and many of the superconducting components can only operate at normal temperatures or even ultra-low temperatures. Therefore, supercomputers have extremely high requirements for heat dissipation.

Hydraulic oil may not be called hydraulic oil, but it does more than just play a transmission role in hydraulic equipment.

If the hydraulic system overheats, a series of performance effects will be affected, so hydraulic oil often has extremely high specific heat capacity and thermal conductivity.

Simply put, the specific heat capacity determines the upper limit of the heat absorption capacity of a unit substance, and the thermal conductivity determines the heat absorption speed. The higher the specific heat capacity and thermal conductivity, the better the heat dissipation and cooling effect.

And because it is oil, it can even directly immerse electronic components for all-round heat dissipation.

Therefore, many high-grade hydraulic oils are not only used as hydraulic transmission media, but also as coolants for many equipment.

Especially this type of supercomputer usually uses high-grade hydraulic oil!

Lin Yu immediately became energetic and quickly opened other electronic waste, digging out the entire wardrobe-like supercomputer.

As expected, it was just an empty shell, and all the valuable electronic components inside had been dismantled.

But with a slight shake, the sound of extremely sticky liquid flowing could be heard from the middle of the shell.

This supercomputer not only uses oil immersion cooling internally, but also fills a large amount of coolant in the outer casing.

"Master Zhang, I want this supercomputer cabinet. It's quite honorable to use as a decoration."

Lin Yu remained calm and called out to Old Man Zhang.

"Hey, ten thousand, no price."

Old Man Zhang chuckled and looked at Lin Yu with a bit of contentment in his eyes.

"Ten thousand? You might as well grab it."

Lin Yu's face twitched.

Ten thousand, he only spent 200,000 to build a mecha.

If we only talk about the shell of the supercomputer chassis, then this one is definitely a big one.

But if high-grade hydraulic oil is included, even if it is used, as long as it has not aged or failed, it can still be considered a reasonable price.

All I can say is that this old man’s vision is really poisonous.

"can it be cheaper?"

Now that the family was well established, Lin Yu simply gave up on picking up the slack and could only shamelessly raise the price.

There is no way, he really can't afford 10,000 yuan now.

I only managed to get 200,000 yuan after scraping here and there. With the production of Daybreak having completely bottomed out, I only had less than 5,000 yuan in my pocket.

This amount of money is more than enough to buy hydraulic oil if it is used to detect leaks, but if you really want to buy it at the standard market price, it is definitely not enough.

"Hey, that's not possible. At this price, it's already very fair."

Old man Zhang just laughed and shook his head.

"Well, I see you have a few things here that are still usable after some repair. I'll help you repair them, and you can give me a half price."

Lin Yu glanced around and proposed a mutually beneficial plan.

When he was rummaging just now, he saw several items of good value.

But firstly, he doesn't need it, and secondly, it's not easy to pick up the slack from Old Man Zhang.

Just take it out and make a deal. "Oh? Can you fix it?"

Old man Zhang looked Lin Yu up and down suspiciously, but he was obviously also interested in this proposal.

The things he has here are almost all taken back as waste, and basically they are no longer usable.

But if it can be repaired, even if it can only be temporarily repaired for a while, its value will not only be doubled.

However, if someone could repair them easily, then these gadgets would not be reduced to scrap.

Even if you search all the black snake gathering places for these crappy things, you may not be able to find the second one that can be repaired.

"Since I brought it up, of course it can be repaired."

Lin Yu allowed Old Man Zhang to look at him calmly, without any fluctuation in his expression.

He has level 3 mecha engineering. He can even design, manufacture and repair mechas by himself, let alone simpler equipment. He has reached the same goal through different paths, and he can repair common damage easily.

"Okay, you can fix these pieces for me, and I'll give you this supercomputer cabinet directly."

Hearing Lin Yu's decisive nod, without any hint of joking in his expression, Old Man Zhang's face became even more surprised. He glanced at it suspiciously, and finally agreed cheerfully.

"Then it's settled."

Lin Yu immediately stopped talking and asked for some tools from Old Man Zhang. He then picked out a few items and then picked through the scrap pile to remove a bunch of useful parts.

He was seen piecing together things here and there, deftly removing various small parts from various appliances. It didn't take long to actually repair several pieces of equipment one by one without even spending much effort.

As the saying goes, it's not difficult for those who can do it, but it's difficult for those who don't know how to do it. That's it.

"You can actually cultivate?"

Old man Zhang, who was just planning to watch for fun, became more surprised as he looked at his face. Finally, he looked at Lin Yu with a hint of eagerness in his eyes: "Boy Lin, what do you do?"

Without waiting for Lin Yu's answer, he followed up: "Are you interested in coming to work at my place? Cooperation is also possible."

"Okay, whenever I can no longer survive, I will come to Master Zhang to beg for a meal."

Lin Yu didn't keep his words to himself, since they wouldn't make any difference in the situation.

After thanking him, he used the old car to pull up the cabinet and left.

Old man Zhang was reluctant to leave and watched the back of Lin Yu's car go away without moving for a long time.

"Hey."

After a moment, he laughed again and shook his head.

To say that you come to beg for food if you can't survive means that as long as you can survive, you won't come.

This young man has a high spirit.

However, being able to have such a level of skill and knowledge in a poor place like the wasteland is indeed enough to be proud of.

Those who are incompetent are called arrogant, but those who are capable are overconfident.

"The only thing that is valuable about the supercomputer cabinet is the coolant in it... the high-grade hydraulic oil."

He put his hands behind his back and muttered vaguely as he walked towards the lounge chair.

"but……"

"The main control hard drive of the Daybreak III speed car, the main control system inside seems to be simplified by Beihe Heavy Industries using the intelligent control system of its own series of mechas..."

"Myoelectric sensors used for high-precision motion capture, spherical electromagnetic joint shafts..."

"There is also Pioneer Group's two-phase battery. Although its battery life is not as good as that of nuclear batteries, it is better at charging and discharging quickly. If the battery pack is properly made..."

Old Man Zhang habitually considered the few items that Lin Yu had bought from him recently, and suddenly paused for a moment, and an unreasonable idea came to his mind.

"This kid, damn it, isn't he building his own mecha?"

As soon as this idea came up, his eyelids twitched.

If you want high-grade hydraulic oil, you must have a corresponding high-standard hydraulic system.

Coupled with the few things he bought in the past, it was really difficult for him not to think about this.

But soon he regained his sense and understood the impracticality of it.

He had looked at the other party as high as possible.

But using scrap parts to build a mecha is tantamount to designing it from scratch and taking over the entire design and manufacturing process.

This process should normally be at least one group department, with dozens or hundreds of people jointly responsible.

Now one person is responsible for it, and he even has to consider parts adaptation and repair, and make changes and modifications according to circumstances. How can this be done by one person?

Or, to put it another way.

"Mecha engineers, or engineers who can use scrap parts to make mechas by hand in this environment, how could they be reduced to a place like a wasteland?"

Shaking his head and laughing, Old Man Zhang laughed at his inexplicable stupid idea.

The wasteland cannot cultivate mecha engineers, especially the remnants of the wasteland, whether they have received education or not.

And it is absolutely impossible for a true mecha engineer, even the most incompetent one, to be reduced to the level of the wasteland.
