Aside from the aspect of freedom, the curriculum of American high school students is actually not much different from that of Huaguo, which is nothing more than mathematics, physics and chemistry, history and geography students.

Unlike Huaguo, which follows the established chemical reaction equations, the purpose of the American campus chemistry course is to test students' hands-on and innovative abilities.

The person who taught Ye Qiu and them was a middle-aged female teacher in her forties, dressed plainly, and in line with the nature of her work, this female teacher named McGee was also very strict with her students, and it was not easy to get an A under her hands.

"This is the last chemistry class in your high school career, this practice in addition to paying attention to the safety rules, there are no requirements, I just need to see your real results and the final report handed in, I will score according to your table, listen, this is related to whether you can get the ideal results in this semester, I hope you use your brains, Wholeheartedly complete the last practice of your high school years. ”

Mrs. McGee's notice was as concise as ever, she really deserved to be from the real yàn room, she never cared about things other than the real yàn, and after telling her request, she no longer paid attention to the students in the classroom, and sat silently behind the lectern, quietly looking at the students who were doing real yàn with each other.

"What should we do?"

Hearing McGee's request, Ye Qiu couldn't help but make a difficulty, he was a strict partial, he had never failed chemistry or physics at all, and Ye Qiu could only remember one now, that is, the most basic extraction of hydrogen and oxygen with water.

But Ye Qiu promised that if he dared to hand in this real yàn as his chemistry class completion, the stern Mrs. McGee would definitely give herself a red red d unceremoniously, and maybe add a sentence similar to "This is high school, not junior high school." Comments.

But fortunately, it is done in groups, so maybe your teammates will have good ideas.

But when Ye Qiu set his eyes on Branna, who was sitting opposite, and happened to meet the other party's blank and helpless gaze, Ye Qiu couldn't help but have a headache, this stupid girl probably didn't even know how to use the instrument placed on the test bench.

In order not to become a typical example in Mrs. McGee's mind in this course, the desperate Ye Qiu can only pin his hopes on the unreliable Jack, after all, if he can do it for the sake of the FBI elite, the results should be very good.

"Jack, what do you think about this?"

"Oh, dear Cho, as someone who compares me to a fly, are you asking me to help you?"

Although he couldn't see it, just listening to this extremely uplifted tone, Ye Qiu could think that this bastard in his head must now be looking down at himself with his head held high triumphantly, as if to say, "Come and beg me, young man." ”

There was a burst of fire in his heart, and there was no one around him who could make him feel at ease, and Ye Qiu, who was angry, did not respond angrily.

"Don't talk nonsense, I'm not good, how good can you be, in short, you just watch it."

"I really can't stand the joke, okay, I'm afraid of you, just leave it to me, or follow your feelings like last time."

Maybe Ye Qiu's threat played a role, but in short, Jack still honestly agreed to Ye Qiu's request.

Ye Qiu slowly calmed down, a spiritual fluctuation came out from the bottom of his heart, Ye Qiu completely let this fluctuation control his body, selected the materials he needed from the various reagents piled on the real platform, and operated quickly with his hands.

Seeing Ye Qiu's actions, Branna's eyes couldn't help but show a hint of surprise, in Branna's world, chemistry must be very mechanical and boring, but looking at Ye Qiu's skillful rhythmic movements, it was like enjoying a dance.

"White powdered **"

"93% pure ethanol"

"1.3:1.7 ratio"

"Stir well, put it in a container, and start heating and purifying it with an alcohol lamp."

With the support of his soul ability, Ye Qiu was like a sophisticated machine, his fingers flexibly manipulating the chemical reagents, and while the other students were still discussing the practical plan, Ye Qiu had already come up with his own results - two quail eggs-sized, scattered brown crystals.

Branna, who knows nothing about chemistry, doesn't know what Ye Qiu made, and curiously holds the crystal in her hand and fiddles with it, anyway, Ye Qiu made it, although Brana doesn't admit it, but in her heart she still thinks that this Qiu, who always surprises herself, is a very reliable person.

Taking notes in the notebook, Ye Qiu followed Brianna and brought their results to McGee.

"Mrs. McGee, this is my real yàn report, and the finished product of real yàn."

After receiving the report submitted by Ye Qiu, Mrs. McGee did not rush to check it, but looked at the student opposite her with interest, from the time he started to practice it just now, he had noticed that the whole process could be said to be as smooth as a cloud, and he was definitely a good seedling of a real yàn member.

Although it was strange why he didn't have such a talented student before, out of love for Ye Qiufen, Mrs. McGee's originally strict expression showed a rare smile, and asked kindly: "What is the name of the real yàn you made, and what is the function of the two brown crystals?" ”

"I use ** to react with ethanol, and the crystals obtained after purification should be called mercury thunderate, as for the effect, throw it out and estimate it." As he spoke, Ye Qiu gestured to Branna, who was playing with the two brown crystals, seeing Ye Qiu's eyes, he was used to obeying Ye Qiu's arrangement for Branna, and without hesitation, he threw one of the crystals towards the corner of the classroom.

"** with ethanol, mercury rhinoate" Hearing Ye Qiu's explanation, Mrs. McGee always felt as if she had heard this thing somewhere, and when she saw the brown crystal in Branna's hand, she immediately remembered something, and suddenly turned pale with fright, and roared loudly, desperately trying to run over to stop Branna's movements.

"Don't ......"

Unfortunately, a little earlier than McGee's reaction, the crystal in Branna's hand was long before McGee's reaction, and a standard parabola slammed steadily into the desk in the corner.

"Boom"

With a loud bang, a flame suddenly appeared on the desk, and Mrs. McGee's face was mixed with horror and anger because of the reflection of the firelight.
