138: Chapter 138 Electromagnetic Penetration, Shielding Radar

"Shu Yin, come here. I have a big treasure here that needs you to process."

After Jiang Chen returned from the restroom, he assigned a task to Shu Yin.

As he spoke, he handed the lump of... dirt, wrapped in a red plastic bag from his pocket, to Shu Yin.

Shu Yin pinched her nose and took it. The object was not only soft and sticky but also carried a slight residual warmth.

She couldn't help but say: "General Manager Jiang, why have you been so obsessed with these kinds of things lately?"

"What's wrong with this kind of thing? Don't look at how it smells; if we can get results from researching it, it will be very valuable."

Jiang Chen replied dismissively.

This was mud scraped off the Terracotta Warriors. According to General Meng Tian, this mud contained a special substance related to yin-yang material. If it could be extracted, perhaps it could be used to harness the Earth's magnetic field.

However, Jiang Chen's words were filtered through Shu Yin's ears.

What she heard was... [Don't look at how it smells... but it's very fragrant.]

"So, how do you need me to process it?" Shu Yin asked.

Jiang Chen: "There is a special substance in this mud, which currently has no academic name. You can just call it yin-yang material. Just extract this substance."

"yin-yang material? What are its properties?" Shu Yin asked, puzzled. She had been working with materials for so many years and had never heard of such a thing, let alone how to extract it.

Jiang Chen pondered: "I'm not sure about its properties, but if you separate the mud, drain the moisture, and remove the impurities, won't the remaining material with the special structure be the yin-yang material?"

"...Uh, alright, General Manager Jiang, I'll go and extract it."

With a sense of reverence, Shu Yin carefully held the lump and walked toward the laboratory.

Jiang Chen wasn't idle either; he simply followed her to the laboratory.

Jiang Chen sat on the side.

Shu Yin skillfully operated various experimental beakers and microscopes throughout the process.

"Huh, there's actually no E. coli."

Shu Yin used a reagent to extract a small tube, placed it under a microscope, and after slicing it, wanted to analyze its components.

But she glanced at it and didn't see any relevant colonies, which made her feel a bit strange.

Isn't this feces?

Jiang Chen looked up and said: "How could there be E. coli in mud? Don't mutter, just extract the special substance inside quickly."

Jiang Chen sat in front of the computer on the side, which also displayed the footage transmitted from under the microscope.

This was the image magnified tens of thousands of times, and the substances inside were very mixed.

There was water, dirt, stone particles, and numerous impurities.

As for the yin-yang material...

Even with his naked eye, he couldn't distinguish it.

"Alright then."

Shu Yin sat in front of the microscope, operating it while searching for the yin-yang material Jiang Chen mentioned.

However, half an hour later, Shu Yin had screened nearly half of the mud using the elimination method.

In the remaining part, there was a shiny substance with a very strange and rare structure.

Under the magnification of the microscope, it looked like a snowflake with a thousand edges.

"General Manager Jiang, I think I've found the special substance you mentioned."

At this moment, Jiang Chen was dozing off on the side. Hearing Shu Yin's words, he immediately perked up and looked at the computer.

At this glance, he became excited.

This structure was too special; it was most likely it.

So he hurriedly urged: "That's right, that's it. Extract all of these substances, and make sure it's pure!"

"General Manager Jiang, I've been struggling for half an hour just for this tiny bit of substance. If you want 1g, I estimate it will take one or two weeks. I can't do it alone." Shu Yin evaluated.

This thing was difficult to separate.

Jiang Chen pondered for a moment.

Since this substance is related to magnetic fields, would it aggregate on its own under electromagnetic wave resonance at a certain frequency?

Thinking of this, he said to Shu Yin: "You keep working on it; I'll go find someone from the physics laboratory."

There weren't many people in the laboratory at the moment.

But fortunately, there was a researcher working on electromagnetics inside.

After hearing Jiang Chen's requirements, he said: "It depends on which frequency of electromagnetic waves you need; different frequencies require different equipment."

"Bring them all over."

Under Jiang Chen's direction, several pieces of equipment were moved to the chemistry laboratory.

People who didn't know might think Che Guevara had reappeared.

"Let's try 300KHz first." Jiang Chen said.

As soon as his voice fell, the equipment from the physics laboratory began to emit electromagnetic waves at the substance under the microscope.

But the mud didn't react much.

"400KHz!" Still no reaction.

"... 800KHz!"

After dozens of tests, the mud finally had some movement.

The shiny substance inside began to vibrate slightly.

Slowly, it automatically separated from the countless impurities.

"It seems the 800KHz frequency worked." Jiang Chen was overjoyed.

He continued to use this frequency of electromagnetic waves to separate the yin-yang material.

Three hours later, the mud was completely decomposed.

A total of 4g of blue-crystal-colored yin-yang material was extracted.

Jiang Chen looked at this small tube of yin-yang material and exhaled: "Finally got you out."

He handed this tube of yin-yang material to Shu Yin.

"Use everything you've learned to try and perform a complete characteristic test on these substances." Jiang Chen said.

The so-called characteristic test was to see what chemical and physical properties it had.

Many technological applications started from the properties of a material.

"I'll try my best!" Shu Yin said.

She was also encountering this kind of substance for the first time.

It was quite challenging to conduct a comprehensive characteristic test on it.

Five hours later, it was already dark.

Shu Yin was still using over a hundred characteristic test methods she had learned to test this tube of yin-yang material.

As of now, she had already measured dozens of chemical and physical properties of this tube of yin-yang material.

But most of them were not very valuable.

For example: flammability, stability, acidity, alkalinity, oxidation, reduction, combustibility, corrosiveness, toxicity, dehydration...

"Can you do some electromagnetic performance tests?" Jiang Chen reminded her from the side.

Just now, these substances vibrated and separated in the 800KHz electromagnetic waves.

Perhaps it had a huge relationship with electromagnetic waves.

Shu Yin nodded and brought over a device that looked like a small radar.

After less than ten minutes of research, she looked at the radar monitor, which was completely blank, and asked in surprise: "Strange, is this radar broken? Why isn't it imaging?"

Jiang Chen leaned over and watched for a while.

His eyes suddenly lit up!

"This doesn't seem like the radar is broken; it's that the penetration of the electromagnetic waves through this yin-yang material has reached 100%!"

Shu Yin didn't react for a moment, and she asked puzzledly: "So what does this mean?"

"Radar is used to remotely scan objects in the air and underwater; it belongs to a type of invisible electromagnetic wave..."

"If the electromagnetic waves it emits pass straight through without reflecting, how can it form an image?" Jiang Chen explained excitedly.

Shu Yin also reacted, and she widened her eyes and said: "In other words, for radar, this substance is equivalent to being 100% invisible?!"

Many modern anti-radar materials achieve semi-invisibility by interfering with radar electromagnetic waves.

This was the first time a substance could allow electromagnetic waves to pass through 100%.

This meant that the radar was rendered directly ineffective.

"It's almost seven o'clock, you should go off work. I'm going to the port."

Jiang Chen took the tube of yin-yang material, ready to go and apply these substances to the pearl river 888, and then test the powerful radar of the Naval Department Base to see if they could detect it.

Shu Yin hurriedly followed the Longke Academy truck: "Wait for me, General Manager Jiang, I want to go too!"

"Doesn't your family worry about you? You don't have to go." Jiang Chen asked.

Shu Yin hurriedly said: "My parents are on a business trip, and I don't have a boyfriend, so it's fine!"

After speaking, her face flushed, and she wanted to explain further.

But Jiang Chen had already jumped onto the truck.

"Alright then!"

"Get in the car quickly!"

"I can't wait!"

Rumble!

The truck carried the two of them toward the port.
