Nalan Xin'er focused on one of the green stones and listened carefully to the introduction of the chemistry teacher.

"This is a rare natural malachite. It was also called'Qinglanggan' by the ancients. In terms of chemical composition, it is a carbonate mineral containing copper..."

It turned out to be malachite...

No wonder it's rare.

Although this kind of gemstone is gorgeous but not suitable for jewelry, it is not common in the upper class, but the pure texture of malachite is a symbol of extremely nobleness. In the ancient royal family, it was carved into exquisite ornaments to ward off evil and evil spirits. God.

The piece of malachite in the display cabinet was carved into a small piece of mini snuff bottle not as big as a palm, simple and lovely.

The teacher saw that everyone was very interested in gems, so he organized students to line up to observe closely, and even opened the exhibition cabinet to let everyone touch the feel of different minerals.

When it was Nalan Xin'er's turn, she couldn't help but glanced at the malachite a second time before returning to her seat.

The next experimental class is to review some classic experiments.

I heard that the leaders of the Education Department and a large number of education experts will come to the Imperial High School for inspection soon, and the chemistry class has always been the strength of the Imperial High School. A large-scale open chemistry class will be held in the third grade. Therefore, in recent chemistry experiment classes, classic experiments will be practiced repeatedly in order to have excellent performance in public classes.

In this afternoon's class, I will practice a fountain experiment.

Although Nalan Xiner still has some psychological shadows about the beaker and test tube, she still mustered the courage to overcome the psychological obstacle. According to the experimental procedure, the beaker and the rubber tube were assembled step by step, and the syringe was used to draw air, and then placed in the water...

In an instant, a beautiful little fountain bloomed from the surface of the water, it was really beautiful!

The fountain experiment was successful!

Nalan Xin'er smiled, in fact, the chemistry class is not so boring!

Then, the teacher explained several other fountain experiment methods, and Nalan Xin'er listened especially carefully. She found that since she stopped eating the shrimp dumplings made at home, her mind became clearer, her memory and reaction skills were much faster, and she could memorize and digest the knowledge she didn't understand yet.

Soon, the experimental class of the afternoon was over.

She arranged the equipment on the test bench, carried her schoolbag, and walked out of the classroom side by side with He Xiaowu and Chen Xueshu.

But as soon as I stepped out of the door, I heard an exclamation suddenly burst out behind me——

"Stop! Don't leave!"

When I looked back, I saw the chemistry teacher's face full of anger, and his eyes were filled with disbelief and deep disappointment: "Get me back! Stand up! Whoever took something just now, stand up and admit it! Don't force me to use it. Extremly tactics to ask!"

Nalan Xin'er looked at each other with He Xiaowu and Chen Xue.

Lost something?

What can be thrown in the laboratory?

Is it possible, who would steal a test tube beaker back?

But it's useless to steal it back!

Most of the students at Imperial High School are born either rich or expensive. Who would do such a thankless thing?

With deep incomprehension, they followed everyone's footsteps, walked back to the classroom, and stood in rows before the podium.

The chemistry teacher was really angry, and he said sharply, "Who the **** stole that malachite snuff bottle? Did you know that it was a collection of the French royal family? It is invaluable! The principal finally lent it to you from the museum to open it. Eyes, you little rascals are good, and you have the courage to take it for yourself? Who did it? Come out and admit it, don’t hurt others!"

Ah... So it was that piece of malachite.

No wonder the chemistry teacher is so nervous.

Silence, everyone is silent.

Nalan Xin'er squinted at the display cabinet next to her, and sure enough, the malachite was missing!

She raised her eyebrows, her lips pressed tightly.

——【The Eighteenth of Thief Little Theater】——

Uncle Dongfang: Wife, you stole malachite?

Miss Xin'er: fart, does sister look like a thief?

Uncle Dongfang: Like! The first time I met, you stole the seed of the Lord; the second time you met, you stole the Lord’s heart... This technique is a peerless thief!

Miss Xin'er: Get out, go to death...
