Sail across the sea

Chapter 3 My Home is a Fertilizer Factory

"Hand in the test paper? Are you giving up the treatment..."

The black-faced teacher couldn't help but want to make a mockery, but his eyes fell on the test paper in Gao Fan's hand, but he froze all of a sudden.

Hey, this paper is actually finished, and it doesn't seem like random graffiti at first glance, but somewhat organized.

"Let me see."

The black-faced teacher took Gao Fan's paper and looked at it at a glance, with some surprise gradually appearing on his face.

"you……"

The black-faced teacher switched his gaze to the X-ray mode, and began to look up and down at Gao Fan, trying to see where Gao Fan was hiding his body.In fact, he had been observing Gao Fan the whole time just now, seeing Gao Fan writing vigorously on the test paper without raising his head, it didn't look like he was cheating at all.

As a senior middle school teacher, the black-faced teacher knows that it is impossible to achieve such a smooth and smooth state by copying cheat sheets in the exam.What's more, this is a chemistry competition, and the questions on the test paper cover dozens of different knowledge points, and there are many detours.Unless Gao Fan obtained the test paper in advance and asked someone to prepare the answers, even if he could bring two chemistry textbooks to the examination room privately, he would not be able to complete the test paper perfectly within 20 minutes.

"Since you know how to do it, why did you sleep just now?" the black-faced teacher asked.

"Uh..." Gao Fan didn't know what to say, could he say that it wasn't him who fell asleep just now but his predecessor Gao Fan?
"It's really jet lag that hasn't reversed..."

Gao Fan could only resort to nonsense again.

"I've collected the papers, you can't leave the classroom now, so as not to affect other students."

The black-faced teacher glared at Gao Fan, then put the paper in his hand, and said to the students in the classroom: "There are still five minutes left, please hurry up!"

"Dingling!"

The melodious bell rang, and almost everyone in the classroom stopped their pens and sighed in unison.I say "almost all" because it doesn't include Gao Fan who was pinned in a daze on the seat by the black-faced teacher.He firmly believes that the so-called not being able to leave the classroom after handing in the paper is just a punishment for him by the black-faced teacher. The fact that his ex slept for 90 minutes is really too much to draw hatred.

"Hey, Gao Fan, how's it going, is the jet lag reversed?"

After handing over the test papers to the invigilator, the boy sitting in front of Huang Chunyan who secretly gave Gao Fan a thumbs up turned around and threw himself in front of Gao Fan, laughing and repeating the stalk Gao Fan used.

The concept of jet lag is not popular nowadays, but high school students have heard of it. When studying world geography in junior high school, it is inevitable to talk about jet lag. The teacher also said that foreigners need such unpopular knowledge as jet lag when they come to China .

Gao Fan came from Cangtang to Ruizhang and claimed to be jet-lagged. This kind of spoof can only be regarded as a very cold joke in the Internet age, but in this age, people play memes less and the jokes are very low. He has been trying his best to hold back his laughter, now that the exam is over, how can he hold it back.

Gao Fan recognized that the boy's name was Fang Rui, and he was one of the four contestants from Cangtang No. [-] Middle School who came with him to participate in the semi-finals.Gao Fan's second and seventh class is the top class of the second grade. The four contestants who came to take the exam this time are all in this class, so they are familiar with each other.Fang Rui has a very good relationship with his predecessor Gao Fan on weekdays, and he doesn't feel that Gao Fan's grades are not good enough so he doesn't want to be friends with Gao Fan.

Gao Fan was about to say something to Fang Rui, when the boy sitting in front of him during the exam also turned around, but he didn't speak to him, but went to Huang Chunyan:
"Huang Chunyan, did the last experimental question result in blue precipitation?"

This boy is another one of the four contestants in Cangtang No. [-] Middle School. His name is Zhang Wei. His grades are usually quite good, and he can basically be stable among the top five in his grade.Gao Fan remembered that during the training period of the Huajing team, and on the way from Cangtang to Ruizhang by train this time, Zhang Wei was looking for various opportunities to strike up a conversation with Huang Chunyan, even if Huang Chunyan ignored him, he Also still enjoy it.

From the perspective of Gao Fan's later generations, this is a licking dog that cannot be housed.

In this era, the ethos of primary and secondary schools in [-]th-tier cities like Cangtang is still very feudal, and boys and girls basically don't talk to each other.However, this rule of not speaking is limited to the daily environment of the class. In the scene where a group of people take the train to other places to take the exam, everyone will naturally lift the ban, and even desperately create opportunities to strike up a conversation. Consolation has long been curious about students of the opposite sex.

Hearing Zhang Wei's question, Huang Chunyan, who was packing up stationery, did not answer directly, but turned her head to Gao Fan, blinked her big beautiful eyes and asked, "Gao Fan, why did you hand in the paper early just now? Listen to the invigilator, You seem to have finished it all."

"I just drew a few random sketches, and I handed it in early when I saw that it was hopeless." Gao Fan replied modestly.

"Then the last experimental question of ammonia water and copper sulfate, did you also do it?" Huang Chunyan asked.

"I did this." Gao Fan said, "Don't forget, my family works in a fertilizer factory, and I grew up smelling of ammonia."

"So, what's the final result?"

"The final result should be a black precipitate. The sulfuric acid added first neutralizes the ammonia water, and the sulfuric acid is further poured in. The copper hydroxide becomes copper sulfate, and then hydrogen sulfide is introduced to form copper sulfide. Copper sulfide is insoluble in water. , forming a black precipitate.

"Ah, that's it..."

There was a look of disappointment on Huang Chunyan's face, clearly realizing that she had done something wrong.

"Huang Chunyan, what Gao Fan said may not be right. The key point of this question is to calculate the ratio of ammonia water and sulfuric acid. Whoever says it will be able to neutralize it." Zhang Wei quickly comforted Huang Chunyan, not caring that Gao Fan heard this. What would it feel like.

"Oh, that's right, just go out and ask Teacher Wen, why are you in a hurry. Let's go, Teacher Wen is still waiting for us outside, let's go." Fang Rui smoothed things over, and then did not wait for Huang Chunyan and What Zhang Wei said, he pulled Gao Fan out, smiling as he walked, "Hee hee, Gao Fan, I didn't realize that you are so humorous, I must tell everyone about jet lag when I go back. Guaranteed to make everyone's belly laugh."

Everyone walked out of the classroom, and rushed towards a strong man in his forties, with a crew-shaven head and a Chinese tunic suit. He looked like a typical middle school teacher.Seeing four students, he couldn't wait to ask:

"How about it, how did you do in the exam!"

Gao Fan recognized that this person was the leader of their trip, Wen Xiaojian, the director of the chemistry teaching and research section of Cangtang No. [-] Middle School.He was about to answer a sentence, but Wen Xiaojian's eyes only flicked over the other people, and finally stopped on Huang Chunyan:

"Huang Chunyan, I heard that the topic is difficult, have you finished it?"
