Li Dejin specially posted the results of the last test in the class, and praised Liu Sen fiercely.

"At the end of the second year of high school, there is a lot of pressure, and you can achieve phoenix nirvana if you resist the pressure, just like Liu Sen, who is not arrogant or impatient, has improved a lot in mathematics, and has achieved a full score in this test. ”

is equivalent to official certification, although Liu Sen has behaved strangely recently, he is still hated, and he has indeed made a lot of envy energy this time, 1000+.

In particular, Qiao Yu provided a wave of 150+ jealousy energy, he was the second in this test, with 115 points, compared to Liu Sen's full score, he was too dim.

Liu Sen's self-confidence coefficient increased from 0.8 to 0.85, and his soul power also reached 69.

Li Kai said to the classmates next to him: "My brother Sen is hanging." ”

Jiang Xue nodded and said to herself: "Brother Sen is already strong, but he doesn't want to show it. ”

Li Dejin continued: "Liu Sen not only got a full score in the last test, but also gave a very ingenious solution to the big questions, and even more than one solution. ”

Jiang Xue was the first to applaud, she could only ask two questions a day, now it's okay, you can listen to one class.

How embarrassing is this, Liu Sen smiled reservedly, lowered his head and secretly laughed.

The spiritual power has accumulated to 2000+.

People are afraid of being famous, and pigs are afraid of being strong.

In the first class in the afternoon, chemistry teacher Yin Jie mentioned Liu Sen, "I heard Mr. Li say, you have made great progress in mathematics, how is chemistry? Analyze the redox reaction: 3NF3 + 5H2O = 2NO + HNO3 + 9HF." ”

Liu Sen was suddenly a little confused, and looked at it for a while.

"Why? I don't know? ”

Qiao Yu pursed his lips and said in his heart, it won't be now, there is a fart for partial subjects, and the college entrance examination still depends on the total score.

Jiang Xue wondered, how could Brother Sen think about it for so long, did he see any deep meaning? Let me take a look again, is there a hole in this question? It's quite simple, the valencies of H and O have not changed.

I didn't have an appointment, and I had to finish it with tears in my eyes.

Liu Sen spent 20 points of spiritual power to solve the problem and answered: "In the reaction, only the valency of N element changes, NF3 is both an oxidant and a reducing agent, NF3 generates NO to be reduced, NF3 generates HNO3, which is oxidized, the ratio of the amount of reducing agent to oxidant is 1:2, in addition, NO is easy to react with O2 in the air to form a brown-red gas NO2......"

After answering this question, Liu Sen silently found the chemistry book and started from the first chapter of stoichiometry.

"4 mol of gas A and 2 mol of B gas are mixed in a 2 L container and the following reaction occurs under certain conditions...... Liu Sen, you can answer. ”

Liu Sen, who had just digested and comprehended the first chapter, burst into tears and spent another 20 points of spiritual power.

It was mentioned three times in one lesson.

Liu Sen didn't know that Li Dejin paid more attention to him with all the subject teachers, so that he could perform more and enhance his self-confidence.

At the end of class, Yuan Gang pushed down the glasses with a thick bottom of the bottle of wine and said enviously: "Brother Sen, your chemistry is also spicy, I worship you." ”

Liu Sen wanted to scold, but he couldn't hold back, just because a few lights flashed.

Gain Yuan Gang's envy energy +50.

Gain Qiao Yu's Hate Energy +120.

Gain Jiang Xue's envy energy +20.

……

Liu Sen glanced at Jiang Xue with disdain, why don't you have Yuan Gang's feelings for me.

also gained 200+ envy energy from other students, with a total of 400 spiritual power.

Yes, the gains from good performance in class still outweigh the expenses.

In the next physics class, the physics teacher also mentioned Liu Sen three times, and the envy energy was significantly reduced, and he only gained 150 spiritual power.

The emotions of the students have a certain immunity to the same affairs.

Pretending to be forced, we must bring forth the new, we must innovate.

Liu Sen also had a headache.

Li Dejin chatted with several teachers in the same office, and also talked about Liu Sen, generally in the late sophomore year of high school, there are indeed some students who originally performed average will suddenly improve their grades.

Because these students didn't care about playing blindly in the early stage, as soon as the pressure of the second semester of the second semester of high school came, they began to stand out.

Chemistry teacher Yin Jie is the head teacher of class 5, and when he came back from class, he said to Li Dejin: "Liu Sen has really improved a lot, I deliberately found three easy-to-mistake questions, he analyzed them all comprehensively, and it can be seen that he understands the basic knowledge very well." ”

"Yes, he's been a lot more proactive lately, and he lacks some self-confidence, and I'm looking forward to him, and in the third period, I arranged for him to tell the students about the last math test paper. ”

"It won't be a problem, will it?"

There is a big difference between being able to do it yourself and telling it in simple terms, and Yin Jie has this question.

"No problem, I read his exam paper three times and did it perfectly. Li Dejin's attitude has changed a lot, and he has special trust in Liu Sen, expecting him to create miracles, "And I specially asked Jiang Xue, she asked Liu Sen questions every day, and she also said that Liu Sen was very strong." ”

Yin Jie nodded, Jiang Xue is a Top5, and he studies seriously, is steady, and will not lie, but he moved his mind a little, and suddenly asked, "Teacher Li, do you know the placebo effect?"

Li Dejin didn't know, and said ambiguously, "I seem to have heard it, what is it?"

"There's a medical term called the placebo effect, and during World War II, the U.S. military suffered heavy casualties in the battle to capture the beaches of southern Italy, and the analgesic morphine quickly ran out. But the wounded soldiers kept coming, and they all howled for the doctor to ask for morphine, so what could I do? One nurse had to use saline instead of morphine and inject it into the wounded, while reassuring the soldiers that they were injected with strong analgesics. ”

"This is a helpless move for a dead horse to be a live horse doctor. But what happened next really left the anesthesiologists and nurses in the army dumbfounded. After injecting the saline, the wounded soldiers actually stopped wailing, and the pain stopped. This is the placebo effect, and the role of our teachers is actually a placebo for most students. ”

"What does Teacher Yin mean?"

"In the most critical stage of the second year of high school, there is nothing more effective than the exemplary role of creating miracles, and it is better to put the third self-study class of our two classes in the lecture hall of the school auditorium. ”

"Isn't this a bit of a big deal?" Li Dejin couldn't decide for a while.

"It's not big, it's not big at all. ”

With that, Yin Jie went to inform the students in the class.

Li Dejin was stunned, a little uneasy in his heart, Liu Sen, don't drop the chain for me.

The system prompted Yin Jie to envy the energy of 30, which made Liu Sen secretly happy.

In the third self-study class, Li Dejin entered the classroom and told everyone to go to the big classroom in the back auditorium, and specially said to Liu Sen: "Class 5 students also go and listen, don't be nervous, just like in the classroom, you can talk how you want." ”

Liu Sen's chicken is frozen! Students, envy a little more energy.

The students of Class 5 listened to the instructions of the head teacher Yin Jie and went to the large classroom in the auditorium.

Han Ru frowned and didn't think much about going.
