love you like a song

Of course, Mu Zi'an didn't want to get an accurate answer when she asked this question. If Gu Nan really wanted to do something to her, then this question would be nonsense and meaningless at all.

To be precise, Mu Zi'an wanted to test Gu Nan.

If she said yes, she probably didn't care about it, and at worst, she would pay Gu Nan all her life.

Although, as a conservative spinster in her 30s, Mu Zi'an certainly didn't have a strong heart, and it was very possible that she would faint halfway through watching herself being manipulated.

To Mu Zi'an's surprise, Gu Nan asked back with a puzzled face after hearing this sentence. "What are you doing with your pants off?"

Even Shi Qing looked at her inexplicably.

Don't you want to play 3some...?Want me to make it clear?Mu Zian thought, narrowed his eyes, and said. "Don't you need to take off your pants?"

As soon as Mu Zi'an finished saying this, Shi Qing's eyes swept over her, and he suddenly burst out laughing silently.Mu Zi'an gave Shi Qing an innocent look.

"why are you laughing?"

Shi Qing looked at Mu Zi'an, the curvature of his face became bigger, this time he couldn't stop laughing and coughed, almost out of breath.

Gu Nan also felt that Mu Zi'an had misunderstood something, and said.

"Although I don't understand what you are talking about, Doudou." She tried to explain. "I just want you to experience the training you did on the eve of the International Chemistry Olympiad."

As soon as Gu Nan finished saying this, Mu Zi'an suddenly understood.The pre-exam training she mentioned is called a low temperature effect test.

To put it simply, it is to let you experience the process of elevated adrenaline hormones, rapid brain operation, and sharply improved thinking in a low-temperature environment.Many people can concentrate on doing the questions under low temperature conditions, which is very efficient.

Generally speaking, in a comfortable situation, it is difficult to concentrate on the problem.So even though today's classrooms are getting warmer and warmer, there are more and more people with poor academic performance.

Gu Nan's explanation reassured Mu Zi'an slightly, she gave Shi Qing who was still smiling, slowly unbuttoned her, and took off the first coat.At this time, the temperature in the room was not high.

People who have studied biology have a common sense. If you don't want to catch a cold during winter swimming, you must make more preparations when undressing.

For example, take off your clothes slowly, and only take off a piece of clothing when you feel that your bones are frozen solid.After taking off all the clothes, immerse them in cold water, so that the heat will be lost less.And those who drink to keep out the cold before winter swimming are actually fools.

That would dissipate more heat, but it wouldn't last long.

People who drink probably want to boost their courage.

Mu Zi'an naturally didn't want to catch a cold, so he took off the second one slowly after he felt almost used to it.

During this period, Gu Nan took out two papers from the room, they were almost ready, and said to Shi Qing and Mu Zi'an. "Come here, both of you."

When Mu Zi'an walked over, he felt that his surroundings were cool. Although it wasn't too cold, it was definitely not comfortable.She rubbed her finger reluctantly to keep it from stiffening.

He sat down on the chair trembling slightly, secretly rejoicing: Fortunately, it was a wooden chair, not an iron one.

Gu Nan looked at his watch and said. "Let's get started. You and Shi Qing have 10 minutes to complete the ten multiple-choice questions, and any extra second will be considered invalid."

Mu Zi'an looked at Gu Nan speechlessly.

So cruel?Co-authoring a question in 1 minute?

Then, she stopped thinking about it and looked at the questions carefully.

The questions are all college entrance examination types, but they are also the first few questions that give points. One question in 1 minute is definitely not difficult for a senior high school student, let alone for Mu Zi'an, it is even easier, and it is not as difficult as the additional test.

So Mu Zi'an had already finished all the questions within two brush strokes, completely killing the genius little boy who was still working on the questions, and handed in the paper while he was stunned.

Of course, this result is also due to Mu Zi'an's amazing analytical ability, which is not only fast, but also accurate.

This kind of talent is something that ordinary people may not be able to achieve even if they have worked for 20 years.

Gu Nan corrected it for her, and everything was correct. Looking at the time, it only took 4 minutes.After some calculation, it was almost 3 minutes faster than Shi Qing.

Gu Nan nodded, took out two papers from nowhere, handed one to Shi Qing and the other to Mu Zi'an.

"You all did a good job. This time, it takes 10 minutes to complete fifteen questions."

If this is still the case, then Mu Zi'an is really freezing here for nothing.Silently browsing through the questions, she glanced at Shi Qing who was serious and had already started to work on the questions, she couldn't help curling her lips.

"Nannan, can I do it one by one? These questions are really not worth doing again."

Gu Nan's expression didn't change. "No. You have nine minutes."

Mu Zi'an picked up the pen in dismay and began to calculate the problem.The first few questions went well, but when it came to the seventh judgment question, it was suddenly divided into five sub-questions...

In fact, this is a total of nineteen questions.

Moreover, the seventh question is... how to describe it, Mu Zi'an thought.

In the 20th century, this type of question was considered a very common basic question. Although it is not difficult, it is definitely not something that many people can figure out, because it has pitfalls.

Trap questions are questions that are completely different from normal people's thinking. These questions have to consider relatively partial knowledge.So being able to make a good trap question is already a wonderful thing.

Mu Zi'an secretly smiled, and started answering the questions directly.

1. Organic matter is flammable.

Wrong, carbon tetrachloride is nonflammable, and it is a highly effective fire extinguishing agent.

2. Dichloromethane is a structure.

Yes, because methane is not a planar structure but a regular tetrahedral structure, so dichloromethane has only one structure.

3. Hydrocarbons with more than 4 carbon atoms are liquid or solid at normal temperature and pressure.

Wrong, neopentane is an exception, it has a boiling point of 9.5°C and is a gas.

4. Ethylene in methane cannot be removed with acidic potassium permanganate solution.

Yes, ethylene is oxidized by acidic potassium permanganate to produce carbon dioxide, so it cannot achieve the purpose of removing impurities and must be treated with soda lime.

5. The double bond energy is small, unstable and easy to break.

Wrong, only one of the double bonds meets the above conditions.

Mu Zi'an made it instantly.

For her, these are indeed very simple questions, like how to stand an egg on the table.But even if it was such a simple question, the high school students in the cram school that Mu Zi'an used to teach still couldn't think of it.

She sighed, and after shivering a few times, she continued to concentrate all her attention on the remaining seven questions, and finished them all in one go.

This time the time was reversed, Shi Qing was half a minute faster than Mu Zi'an.Gu Nan sat on the sofa and gave them points.

It's not that Mu Zi'an didn't want to speed up her thinking, but that she was already so cold that her head was almost frozen.She watched Gu Nan's correcting movements, and kept rubbing her hands to promote blood circulation.

Each red check mark was outlined on the paper. When the seventh question of Mu Zi'an's paper was judged, Gu Nan's hand paused slightly, and he compared Shi Qing's paper again.

Then she gently drew a big tick on the five small questions of the two of them.

"Not bad. You can do this kind of trap right." Gu Nan said while correcting. "When I showed this problem to my students, they still complained that it was difficult."

Mu Zi'an chuckled, but didn't speak.

that's for sure.

In chemistry in the next ten years, the question types will increase exponentially and explosively. Many college entrance examination questions involve university issues of this era, and the question types will continue to be reduced.

At that time, Mu Zi'an still had an impulse to quit his job as a chemistry teacher and become a psychology teacher.Because the chemistry teacher is really working too hard, and if he can't solve these questions, it means that he can't give lectures to the students, which is equivalent to losing his job.

Fortunately, she did not give up, but continued to study chemistry.Otherwise, she won't know anything after rebirth, and naturally she won't be able to show off her chemical ability in front of Gu Nan.

"Fifteen questions are all right again."

Gu Nan spread out the test papers of the two of them, and then said.

"Shi Qing and your high school chemistry are no longer a problem. From now on, Doudou, you have studied five years longer than other junior high school students. This is very good."

Mu Zi'an nodded, and silently corrected in his heart that he had learned more than others for more than 20 years.

Seeing that Gu Nan was about to take out a few more papers, Mu Zi'an's face turned slightly pale, not only because of the cold, but more importantly, she didn't want to do high school papers again, and if she did, she would really be bored.

But how to tell Gu Nan?

She knows all about high school stuff...now she's 12...doesn't make sense? !Then...do you want to say a few words of humility in response to the occasion?Say you are tired and don't want to do the questions?

Mu Zi'an blinked his eyes that were already frozen and confused, and just about to speak, he saw the little boy opposite, because of Gu Nan's words, he started to shake his shoulders, and the amplitude became bigger and bigger.

She watched Shi Qing collapsed in front of the chair with a black line all over her head, out of breath, twitched the corners of her mouth, and said.

"Shi Qing, are you having a convulsion?"

As soon as these words came out, the smile on Shi Qing's face stopped abruptly, his whole body seemed to be choked, his eyes widened in an instant... His face was flushed, and he glanced at Mu Zi'an angrily, He ran straight to Gu Nan's bedroom.
