I accidentally entered the courtyard and became Qin Huairu

Qin Huairu was returning home from get off work, like a light butterfly fluttering in, but suddenly she felt something prick her foot.

She moved her foot, bent down, and picked up the thing that was hurting her foot.

Holding it in her hand, she was stunned.

"This is a diamond!"

"This is such good luck, it's like winning the jackpot!"

"I can find diamonds when I get home from get off work!"

She still remembers the classic advertising slogan from her previous life.

Diamonds are forever, one lasts forever!

At that time, this thing was a must-have hardware for marriage.

Without a diamond ring, the woman will never agree to get married!

But this thing doesn’t seem to be popular in China now!

Qin Huairu couldn't understand.

Looking at the diamond in my hand, the color is good and the clarity is high. It looks to be about two carats.

Qin Huairu originally wanted to go home directly, but after thinking about it, she decided to stay where she was to see if someone had lost it.

After waiting for a while, I saw a young man running towards me in a hurry like an ant on hot pan.

While running, he was looking around for something.

Soon, he arrived beside Qin Huairu.

"Comrade, have you seen a stone this big and crystal clear?"

Qin Huairu chuckled and spread out her hands. A small white crystal appeared in her palm.

“Is this it?!”

The young man was so excited! "Yes, yes, that's it!"

"Thank you so much!"

"If I can't find this, I'll make a mistake!"

Qin Huairu raised the corner of her mouth slightly, uttered a scornful laugh, and retracted her hand.

"Tell me first, what is this thing? How are you going to prove that you lost it?"

The young man was obviously stunned!

"I'm telling you, can you understand?"

The young man looked at Qin Huairu with disdain, convinced that she had no idea what she was holding in her hand!

Qin Huairu sneered and walked away without any regrets.

When the young man saw Qin Huairu was about to leave, he hurriedly stepped forward and stretched out his hand to block her way.

"You haven't returned my stuff yet!"

Qin Huairu looked at the young man in front of her helplessly.

"Comrade, if you can't prove that this thing is yours, then I can't give it to you. Do you understand?"

"Okay, if you keep pestering me like this, I'll call the police!"

Not only was the young man not afraid at all, but he strongly agreed with Qin Huairu's proposal.

"Well, then let's let the police judge the matter!"

Just then, an old man came running from a distance, panting.

"Qiao Mu, have you found it?"

The young man looked behind him! "Director Qi, this female comrade found the things!"

"But she insisted that I prove that this thing is mine, and I'm explaining it to her right now!"

After hearing this, the old man walked up to Qin Huairu with a smile.

At the same time, he reached out and pulled the young man named Qiao Mu aside.

"Comrade, this thing is indeed mine. This is my ID!" As he said this, he handed his ID to Qin Huairu.

"Comrade, I'm a teacher at Kyoto University!"

“We are conducting research on minerals.”

"The ore you picked up was bought from abroad by us!"

"It's very precious! Can you give it back to us?"

Qin Huairu nodded! "I said, as long as you can prove that this thing is yours, then I will give it to you!"

"It's no use just talking to me. You have to tell me what this thing is called and where it comes from. If you tell me correctly, I'll give it to you!"

Director Qi smiled and nodded! "Comrade, you are very vigilant, which is good!"

"Then I'll tell you!"

The old man smiled and began to explain to Qin Huairu! "Diamonds, this precious gem, are mainly composed of carbon. They have been formed in the high temperature and high pressure environment deep in the earth's crust for billions of years, and finally present an amazingly bright light."

"Diamonds are produced all over the world, and some of the most famous sources include South Africa, Canada, Australia and Russia. The unique geological conditions in these regions provide an ideal environment for the formation of diamonds."

"In these locations, diamonds are often hidden deep in mines or river alluvial deposits. Miners need to work hard and use advanced technology and tools to dig out these precious gems."

“Each diamond carries with it a mystery and history from deep within the Earth, and their unique qualities and brilliance make them among the most cherished gemstones.”

Qin Huairu almost laughed out loud after hearing what the great professor in front of her said.

She thought, although this thing is precious, she knew that in South Africa, diamond mines are everywhere!

The reason why they are precious is that those minerals are controlled by oligarchs and big capital.

If I remember correctly, when the technology in China matured, it was possible to produce synthetic diamonds. India bought these artificial diamonds and made a lot of money from Europeans and Americans.

To this end, the Americans also changed the international diamond identification rules.

However, they did not expect that a certain big boss in our country directly took over several diamond appraisal agencies.

This dealt a heavy blow to the Europeans and Americans, causing them to suffer a great loss, but also made the Chinese people feel proud!

When Qin Huairu thought about this, she realized that the thing belonged to someone else, so she immediately handed the two-carat diamond to the old man.

After returning the things, Qin Huairu prepared to go home.

But as soon as I went out, I heard the old man named Qi sighing.

"Just find it back!"

"Alas! What a pity! Without rare metals like rhodium, you can only learn theoretical knowledge!"

"Rhodium, is it really such a coincidence?"

"How many kilograms are there in your system space?"

"It's useless to keep this thing. It would be great if I could exchange it for some money!"

Thinking of this, Qin Huairu, who had already walked out, stepped back after hearing the old man's words.

"Let me find out what you want the rhodium for!"

Before the old man could speak, the young man, Qiao Mu, interrupted and spoke.

"What does this have to do with you? Do you know what rhodium is?"

There was an air of contempt in his words towards Qin Huairu, which made Qin Huairu very angry.

"Isn't it just rhodium? Isn't it just a metal?"

"I have it at home. If you don't want to tell me, forget it. I won't even ask!"

Qin Huairu was like a little child, she said this angrily and was about to leave.

Unexpectedly, her words shocked Mr. Qi.

He didn't care about the difference between men and women, and came over and grabbed Qin Huairu's arm.

After grabbing his hand, he realized that he was being rude and quickly let go.

"Comrade, can you tell me how you got this rare metal called rhodium?"

Qin Huairu laughed! "Why can't I have it? It's passed down from my family!"

Mr. Qi didn't think Qin Huairu was lying.

"Then comrade, can we go to your house and see the rhodium in your hand?"

Qin Huairu was secretly happy when she saw the fish took the bait.

"Okay, that's okay, just follow me!"

After she finished speaking, she led the way, and Old Qi and the young man named Qiao Mu followed her back to the courtyard.
