From scrap mecha to sci-fi heaven

"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 comes from the selected conventional recyclable materials, which are 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.

"Um?"

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 tiniest 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 kind 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 is still reasonably priced.

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 by scraping here and there, but as Daybreak's production has completely bottomed out, I only have 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 fixed."

Lin Yu calmly let Old Man Zhang look at him, his expression did not fluctuate at all.

He had a level 3 mecha engineering, and he could design, manufacture and repair mechas by himself, not to mention simpler equipment. Different paths led to the same goal. I dare not say that I can build them, but it is still easy to repair common damages.

"Okay, you fix these for me, and I will give you this supercomputer cabinet directly."

Hearing Lin Yu nod decisively, and there was no joking in his expression, Old Man Zhang's face was more surprised, and he looked at him suspiciously, and finally agreed with a straightforward look.

"Then it's settled."

Lin Yu did not waste words immediately, and asked Old Man Zhang for some tools, then picked out a few things separately, and picked out a bunch of useful parts from the waste pile.

I saw him pieced together and skillfully removed various small parts from various tools. It didn't take long for him to repair several equipment one by one, and it didn't even take much effort.

As the saying goes, it is not difficult for those who know, but difficult for those who don't. This is the case.

"You can actually repair it?"

The more Zhang Lao, who was just planning to have fun, the more astonished he looked, and finally looked at Lin Yu with a hint of eagerness: "Lin boy, what do you do?"

Without waiting for Lin Yu to answer, he followed up with: "Are you interested in working for me? Cooperation is also fine."

"Okay, when I can't survive, I will come to you, Master Zhang, to ask for a bowl of rice."

Lin Yu didn't say anything final, anyway, polite words won't hurt.

After thanking him, he used the small broken car left by his original body to pull the cabinet and left directly.

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

"Hey."

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

Saying that you can't survive and come to ask for a bowl of rice, it means that as long as you can survive, you won't come.

This young man is very ambitious.

However, being able to have such skills and knowledge in this broken place of wasteland is indeed enough to be proud of.

Only those who have no ability are arrogant, and those who have ability are confident.

"Supercomputer cabinet, this thing, the only valuable thing is the coolant inside... high-grade hydraulic oil."

He put his hands behind his back and walked towards the recliner, mumbling vaguely.

"But..."

"The main control hard disk of the Dawn Breaking III flying car, the main control system inside seems to be simplified by Beihe Heavy Industry using the intelligent control system of its own series of mechas..."

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

"And the Pioneer Group's two-phase battery, although the battery life is not as good as nuclear batteries, it can be charged and discharged quickly. If it is made into a battery pack reasonably..."

Old man Zhang habitually calculated the few items that Lin Yu had bought from him recently, and suddenly paused slightly, and an idea came to his mind for no reason.

"This kid, damn, is he making a mecha himself?"

When this thought came up, his eyelids jumped.

If you want high-grade hydraulic oil, then there must be a corresponding high-specification hydraulic system.

Adding to the few things he bought in the past, it was really hard for him not to think about this.

But soon he regained his sanity and realized the impracticality.

He had already looked up to the other party as much as possible.

But using waste parts to make a mecha is tantamount to designing it from scratch, and taking charge of the entire design and manufacturing process.

And this process should normally be at least a group department, with dozens or hundreds of people jointly responsible.

Now it is all done by one person, and even has to consider parts adaptation and maintenance, and change and modify the plan in the middle of the process. How can this be done by one person?

Or, put it another way.

"How can a mecha engineer, or an engineer who can use waste parts to rub mechas in this environment, fall into a place like the wasteland."

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

The wasteland cannot produce mecha engineers, especially the survivors of the wasteland, who may or may not have received any education.

And a real mecha engineer, even the most inexperienced one, would never fall to the level of coming to the wasteland.
