The Fiery Era: Starting from Longxugou

"Teacher, I've finished writing!"

Just over half an hour later, Zhao Shi'an handed in his paper again.

"It seems you're doing quite well in physics too!"

Hu Chengzhi took the test paper, glanced at it, gave a word of praise, and then said:

"You said you were trying to take three exams this morning. We still have some time, so how about we take one more?"

After Hu Chengzhi finished speaking, he looked at Zhao Shi'an with great interest.

"Please continue with the exam! Thank you, teacher!"

Zhao Shi'an nodded in agreement.

"Haha! Okay, you can rest for a bit, and we'll start the chemistry test shortly!"

Upon hearing this, Hu Chengzhi admired Zhao Shi'an even more.

"Okay, teacher, I'll go to the restroom first!"

This time, Zhao Shi'an didn't refuse. He had been writing papers for over an hour and needed to stretch his legs.

Go!

After Hu Chengzhi waved and watched Zhao Shi'an leave, the once quiet office suddenly became lively, with teachers who didn't have classes crowding around Hu Chengzhi to ask questions.

"Old Hu, what's going on? Did your class really produce a genius? Finished the math and physics tests in just over an hour?"

"Yeah! Old Hu, you seem so happy, Zhao Shi'an must have done well in school!"

"Teacher Hu, what's going on? Is Zhao Shi'an's grade really that good?"

Li Shuting was somewhat incredulous upon hearing this.

"You didn't have class just now, so didn't you all see Zhao Shi'an doing his homework?"

"I saw him, but I only know he was fast at answering questions. I don't know how he did on the test."

"Old Hu, stop keeping us in suspense and tell everyone!"

"Yes, Teacher Hu, everyone's been waiting!"

"Alright! I'm just teasing you guys. This test was very basic, and Zhao Shi'an got most of it right. It seems he really has a grasp of high school level knowledge!"

As Hu Chengzhi spoke, he handed the test papers in his hand to his three colleagues. Li Shuting snatched a physics test paper, but found that she couldn't understand it. She then asked her colleague next to her for help.

"This question was indeed very basic, basically following the textbook. Zhao Shi'an answered it well!"

After reviewing Zhao Shi'an's exam paper, the teachers in the office all praised him.

"Teacher Zhang, what score did Zhao Shi'an get? Tell us!"

Li Shuting looked at the various symbols on the test paper. Although they seemed familiar, they were not the Russian letters she was familiar with. She was completely bewildered when her colleague praised Zhao Shi'an.

"Haha! Little Li! Sorry, I wasn't paying attention just now. Getting over 90 on both of these tests is really good!"

"Over 90? That high? Then why did he score so much lower on the college entrance exam?"

Li Shuting was very surprised when she heard this. She thought of the college entrance examination questions Zhao Shi'an had done yesterday. He got a maximum score of 68 in math and 60 in physics. How come he got such a high score when he took the exam himself at school?

"Teacher Li, this year's exam questions are different from the college entrance exam, which focuses on selecting talent."

This test is to assess whether Zhao Shi'an has mastered high school knowledge, mainly focusing on the basics, to ensure that he can keep up when he enters the senior year!

Compared to the National College Entrance Examination (Gaokao), our test papers are naturally much simpler!

Hu Chengzhi patiently explained.

"So that's how it is! No wonder there was such a big difference! Hey! Zhao Shi'an's back, let's hurry back and sit down!"

Li Shuting suddenly realized, looked up and saw Zhao Shi'an walking towards the office, and quickly reminded him.

Upon hearing the reminder, the teachers returned to their seats.

Zhao Shi'an knocked on the door and entered the office, then sat down at the temporary examination area.

"Shi'an, how are you? Are you tired? Do you want to rest a little longer?"

Hu Chengzhi asked with concern.

"Teacher, no need, let's begin!"

"Okay! This is the chemistry test I prepared. I saw how quickly you finished the questions, so your basic skills must be very solid. I added an extra question on the spot. Try to do it. It's okay if you can't do it. As long as you pass, it won't affect your ability to skip a grade!"

As he spoke, Hu Chengzhi handed over the chemistry test paper. He had just seen Zhao Shi'an answer the questions very quickly and with a high accuracy rate. As a teacher, he was delighted and immediately gave him a more difficult bonus question.

This question has never been on the college entrance exam. The purpose of setting this question was to curb Zhao Shi'an's arrogance and prevent him from becoming complacent.

"Teacher, I'll try my best to do it!"

Zhao Shi'an nodded, took the test paper, checked it as usual, and only after finding no problems did he start to look at the contents of the test paper.

The content of the mimeographed exam papers was indeed very basic, consisting entirely of material from the textbook.

On the last page, Zhao Shi'an saw an extra question written in pen by the teacher:

Coarse salt often contains impurities such as calcium chloride, magnesium chloride, and mud. Describe the experimental steps for purifying coarse salt.

The requirements are as follows:

(1) Main operating steps;

(2) The reagents added in each step and their functions;

(3) Separation method for each step.

Upon reading the question, Zhao Shi'an was immediately delighted. Wasn't this a classic experiment in modern high school chemistry?

"How was it? Was it a bit difficult? Don't worry, let's do the other questions first. This bonus question, although not beyond the syllabus, is still somewhat complicated. Not only do we need to consider the overall picture, but we also can't introduce any new problems!"

Focus on the questions, and don't let them affect your mindset!

Seeing Zhao Shi'an staring blankly at the bonus question, Hu Chengzhi couldn't help but remind him, afraid that a difficult question would affect his mindset.

While it's good to review all types of questions before checking a test, it can also affect students' mindset by difficult questions, causing them to make mistakes on questions they actually know how to answer, and thus their grades will drop!

"Thank you, teacher, I understand!"

Zhao Shi'an nodded upon hearing this, picked up his pen, and began to answer the questions.

As a modern person, after arriving in this era, he discovered that many of the classic experiments in modern high school textbooks would be considered cutting-edge technology in this era.

The homeroom teacher just said that a difficult question had been added at the last minute. He was curious about what the question was, but after seeing it, he was instantly smitten.

Isn't this just like the crude salt purification process in high school chemistry?

The questions in modern high schools are even more complex than those set by the old teachers.

The questions given by the homeroom teacher only contained three kinds of impurities: calcium chloride, magnesium chloride, and silt.

In modern chemistry, the purification of crude salt includes an additional step of removing sulfate ions.

Compared to these, the extra questions given by the homeroom teacher were only very basic.

Besides the classic experiment of purifying crude salt, other classic experiments include Mendel's pea hybridization experiment, Morgan's fruit fly sex-linked inheritance experiment, the study of chromosomes and genes, the ABO blood type inheritance law, and the artificial induction of polyploidy to cultivate seedless watermelons using colchicine.

However, these genetic contents are portrayed as bourgeois idealism and pseudoscience by the propaganda of the social camp.

However, the true pseudoscience, the "Michurin theory," is widely prevalent.

Whether Zhao Shi'an can be used for other genetics is irrelevant, but colchicine still needs to be used, since it is needed to cultivate seedless watermelons.

But genetics has been labeled as pseudoscience, and who knows how easy it is to obtain colchicine reagent? By the time he gets to university, it'll probably be tough.

Fortunately, he can purify it himself, directly purifying the colchicine from the plant using traditional methods. The concentration doesn't need to be too high to be usable. It is said that colchicine is highly poisonous, but his mental capacity, which extends within a one-meter radius, can do many things and completely counteract the toxicity of colchicine. He is truly a born scientific genius.

With a solution in hand, Zhao Shi'an's mood improved considerably.

Thinking that genetics in this era has been labeled as pseudoscience, and that schools don't even teach the various experimental contents, he was very curious: in the absence of experiments on the ABO blood type inheritance law in genetics, were there many more cuckolds in this era than in modern times?

Blood type can be used to make a simple determination of parentage, which is common knowledge in modern times!

In the 1950s, it was difficult to confirm parent-child relationships. Blood kinship testing was an ancient method and belonged to feudal superstition, so this method could not be used.

Just by looking at whether they look alike, we can't be sure, since there are factors of environmental convergence in living organisms.

From an evolutionary perspective, offspring that imitate their caregivers are more likely to be accepted and protected, and have a higher chance of survival!

As a modern person, he has heard plenty of stories about the beauty of the past: slow travel and the idea that one's life was only enough to love one person!

Talking to older people more often will reveal that the shocking things that happened in their era can seriously impact one's values. At that point, you'll inevitably exclaim: "Old ginger is spicier!"
