After getting the pass, Su Chen had no plans to leave.

"Vice Dean Du?"

Su Chen pointed to the side, "Borrow a phone and use it?" ”

Du Zhifang glanced at him, "What do you kid want to do?" ”

Su Chen explained: "There are some situations that need to be communicated and understood beforehand. ”

"Otherwise, it's a trip for nothing."

Seeing that Su Chen had a nose and eyes to speak, Du Zhifang reluctantly nodded.

Picking up the phone, Su Chen directly dialed a nearby arsenal.

As soon as he picked up the phone on the other side, Su Chen went straight in, "Does your arsenal have a three-phase electric arc furnace?" ”

Three-phase electric arc furnace.

Du Zhifang, who heard this term, raised his eyebrows.

Of course he knew that this thing could be said to be the most advanced smelting furnace at the moment, and the temperature was unusually high, reaching four or five thousand degrees, enough to melt all metal.

This kid.... Could it be that there is really research?

"I'm sorry comrade, we don't have it here, you can ask other places." A reply came out on the phone.

Su Chen hung up the phone, and was about to call the next arsenal again...

Du Zhifang pressed the phone landline and glanced at Su Chen deeply, "No need to call." ”

"The 335 arsenal has a three-phase electric arc furnace."

......

From the map, the straight-line distance from the 425 Research Institute to the 335 Arsenal is a hundred kilometers.

Actually, it's more than that.

It took a full day to take the car before Su Chen successfully arrived at the 335 Arsenal.

Because I said hello in advance, there were people waiting at the door early to answer them.

After a brief greeting, after a long period of greetings, Su Chen met the experienced Sun Gong.

Dressed in camouflage uniform, wearing a helmet, dark-skinned, lean and lean, it is hard to imagine that such an ordinary person is an extremely rare senior engineer.

It is no exaggeration to say that each of them is a national treasure.

"From the 425 Institute?"

Sun Gong smiled, "I specially ran so far, I think it was to make armor for the mechanical power of the exoskeleton, right?" ”

Su Chen was a little surprised, "Sun Gong, how do you know?" ”

"Haha." Sun Gong waved his hand, "What's there not to know about this?" ”

"Before, a person named Shi Weiwei in your 425 courtyard didn't know how many times he came over."

"I was confident every time, and I ended up failing every time."

"I'm used to it."

Saying that, he glanced at Su Chen, "Young man? ”

"Do you think you'll be the exception?"

"It's all here...."Su Chen said, took out a pre-written note from his arms and handed it to Sun Gong, "You have to try it, right?" ”

Sun Gong didn't say much, it was nothing more than opening the furnace to refine some alloys.

How big is it?

Hurry up and finish work in two or three hours.

Anyway, it's just a sample, and then tested.

If not, the young man in front of him will go back and forth from wherever he comes.

He wasn't too familiar with the process.

But it doesn't matter if you don't look at it, Sun Gong was stunned when he saw it.

The slip of paper was densely filled with all kinds of materials.

He took a closer look and found that many metal raw materials were extremely rare, and even the 335 Arsenal did not have this rare metal in stock.

"This..."

"This..."

"This..."

Sun Gong looked up at the young man in front of him, "Are you serious?" ”

"So much mess of metal all together?"

"Are you sure this will really work?"

After more than 20 years in the 335 Arsenal, it was the first time he had seen such an exaggerated alloy material formula.

"Of course." Su Chen said, "If you look carefully, I have remarked the dosage at the back of each material." ”

"I'm not scribbling."

Sun Gong looked down and found that it was indeed the case.

The dosage is noted at the end of each material.

Just now, he was so surprised by the dense material on the note that he ignored the number behind it.

Su Chen said, "It's not just the dosage. ”

"Sun Gong."

"On the second side of the paper, there are also notes on which materials are smelted together, the time of smelting, and the control of temperature."

"Which ones are the second batch, which ones are the third batch, and which ones are put last."

"You can't go wrong with the sequence, the timing, or the temperature."

"A fraction of a millimeter, a thousand miles of loss."

When Sun Gong heard the letter, he turned the note to the second side suspiciously.

found that as Su Chen said, there were a lot of dense writings on it.

Even so, Sun Gong was still a little unimpressed.

I, a senior engineer who has worked in the arsenal for more than 20 years, still don't know how to deal with materials? Can you still not understand the control of temperature? Do you need to write a note on the back of a note to teach me?

Sun Gong's eyes swept slightly, and he found that something was wrong.

Many of the details of the material are not the standard methods written in textbooks.

Instead, it goes straight to the essence through the phenomenon, and the angle is very tricky and spicy, but it is extremely correct.

Because this is something that he has spent more than 20 years and explored little by little from practice.

He is proud of it and treasures it!

In the future, unless the disciples are closed, they will not pass on!

But I didn't expect these things to be written on a note like this!

Sun Gong's face was full of astonishment.

He really couldn't understand how the young man in front of him knew this.

Sun Gong couldn't wait to look behind him, and the astonishment on his face was gradually replaced by surprise.

He found that he couldn't read at all.

Many of the latter special treatments for materials were unheard of for him.

"It's... This?! Sun Gong looked up at Su Chen and said excitedly, "Rubidium, niobium, and zirconium are the three rare metals, why do you want to deal with them like this?" ”

"Shouldn't they be heat treated first?"

Su Chen just smiled, "Sun Gong, don't be in a hurry." ”

"Even if I say it now, you may not understand."

"When we really get there, I'll tell you about it, and you'll understand."

Only then did Sun Gong realize that he was indeed anxious.

But there was no way, in the face of this almost subversive way of dealing with it, he really wanted to know why.

Sun Gong clapped his hands with a look of remorse, "That's right, that's right." ”

"It's time to take it one step at a time."

"What do you see?"

Sun Gong rubbed his hands and said a little impatiently, "Shall we start now?" ”

Su Chen looked at Sun Gong's eager appearance and felt a little funny.

"Before I can do that, I need to confirm a question."

"Do you have all these materials in the note from the 335 Arsenal?"

He didn't want to stop halfway through.

Sun Gong hurriedly took a pen and wrote down the rare metal materials that were lacking with a pen and wrote a list.

Su Chen took this list and called Du Zhifang, saying that the 335 Arsenal was short of some raw materials, could our 425 Research Institute support it?

When Du Zhifang heard this, his heart suddenly became full of doubts.

335 is such a big arsenal, how can there be a shortage of materials?

It's weird!

On second thought, it makes sense that there was a lack of a unique rare metal.

Thinking about it, it's not a big deal, just say okay, there's no problem.

Then Su Chen began to report the list.

After saying it, he directly told Du Zhifang that he was stupid.

He almost jumped out of his chair and said, "What? ”

"You tell me again?!"

"You're just making an armor, and you need so many materials?"

"Why didn't you say you wanted the moon in the sky?"
