Xu Fenglian gave Feng Zhenye an inquiring look. Should she interfere?

Feng Zhenye shook his head slightly and continued to watch.

In fact, he was really curious, after all, Chen Fugui brought him a lot of surprises today.

What if Chen Fugui really studied well? It was just because of his family that he did not take the college entrance examination.

"You come and solve it."

At this time, Feng Manqian took the written questions directly on the coffee table, and a faint fragrance also drifted into Chen Fugui's nose.

The height of 1.85 meters is not a joke. I glanced down and saw a lot of scenery.

It doesn't matter if the question is not, his face is definitely redder than the monkey's butt anyway.

The girl also noticed something was wrong with the problem. Her handsome little face turned red and hurriedly sat back.

Now the look at Chen Fugui has become even more "brutally".

"Sister, I really let Brother Fugui solve this question? This is an additional question, and it took me half an hour to solve it." Feng Haoyu next to him spoke.

"Haoyu, this question is difficult?" Feng Zhenye asked.

Feng Haoyu grabbed his scalp, "I didn't do it at the beginning. I forgot how to write a chemical reaction equation and even looked through the book."

Chen Fugui glanced at the question on the straw paper, "Actually, the solution to this question is very simple."

"Yes, it's very simple."

Feng Manqian beside him picked up his arms and looked teasing.

"Haoyu, don't look at the question that the part of this question seems to be very complicated. In fact, the more such a question is, the easier it is to solve it." Chen Fugui said.

"What are you most afraid of when taking the college entrance examination in the future? You are most afraid of giving very few known conditions. The fewer conditions you give, the more traps you get, the harder it will be to solve."

"The known condition for this question is that an unknown amount of iron and iron oxide is added to the added amount of hydrochloric acid, and a chemical reaction occurs."

"Because it is an excessive amount of hydrochloric acid, the chemical reaction is very sufficient. The first idea for us to solve this problem came out, and the trivalent iron ions inside were gone. Right?"

Feng Haoyu nodded. This is indeed the case.

Feng Manqian next to him frowned, as if this guy didn't know anything?

"What the question asks about how much iron oxide is inside, that's very simple. You don't have to worry about how it reacts inside, and you can solve the problem." Chen Fugui continued.

"Ah? No matter how you react? Then..., how can you solve it?" Feng Haoyu asked in surprise.

Feng Manqian beside him curled his lips, knowing that this guy was bragging and talking nonsense.

"The reaction here is that iron loses electrons, right? The final product is divalent iron ions. Right?" Chen Fugui continued to ask.

Feng Haoyu nodded.

"The old saying goes, it is not difficult to borrow and repay. Losing electrons is equivalent to borrowing electrons. There will inevitably be a party to obtain them, right?" Chen Fugui asked again.

Feng Haoyu nodded.

Feng Zhenye next to him paid attention to the expression of his niece, as if his niece was also thinking about this issue.

"The amount of hydrogen is also given in the question. Can you calculate the number of electrons obtained by taking the amount of hydrogen? It is equivalent to the borrowed money? Then does the number of electrons lost by the iron here also come out?"

Chen Fugui said with a smile.

"Yes, yes, wait a moment."

After Feng Haoyu finished speaking, he picked up the pen and started writing on the straw paper.

"This..., this..., can you solve the problem so simply? Even if Brother Fugui said it, it would take a few minutes?"

Looking at the answer he solved, Feng Haoyu looked unbelievable.

"Haoyu, Fugui's solution to this problem is very good?" Feng Zhenye asked with the excitement in his heart.

"Dad, it's not just very good, it's so good." Feng Haoyu said with a wry smile.

"Just think about it. It took me almost half an hour to flip through the book and write the formula. It only took a few minutes now? If there are really similar questions in the college entrance examination, how much time will I have to save when I use Brother Fugui's method?"

"Actually, this is a trick in chemistry, and it can be regarded as a special feature in chemistry." Chen Fugui said with a smile.

"Because our chemistry problems are often given requirements under complete standards, so we can grasp the law, called the law of conservation."

"No matter what kind of chemical reaction occurs, the mass, atomic weight, number of electrons involved in the substances before and after the reaction will not change."

"As long as you grasp one of them and find a balanced equation, you can make use of it when solving the problem and save a lot of time."

"Well, this is really super awesome. Brother Fugui is so awesome." Feng Haoyu's face turned red with excitement.

"Class Qianqian, do you understand?" Chen Fugui asked Feng Manqian again.

While thinking about Chen Fugui's words, Feng Manqian didn't think much about it and nodded habitually.

Then I realized, what is this guy talking about?

What is Qianqian classmate?

Are you a student who doesn’t know anything?

"You lost. Auntie, is it time to eat? I smelled the smell of smoked chicken and was so greedy." Chen Fugui said with a smile.

"Yes, yes, yes, have a meal first." Xu Fenglian said hurriedly.

"Dad, let our family pay Brother Fugui to take the college entrance examination as well, so that Brother Fugui can pass the exam in one go." Feng Haoyu said.

"Silly boy, do you think that if you give Fugui money, Fugui will take the college entrance examination?" Feng Zhenye touched his head.

"Yes, otherwise Brother Fugui would be so good at studying, it would be a pity if he didn't take the college entrance examination." Feng Haoyu said.

"Haoyu, in fact, it's nothing for me to not take the college entrance examination. I'm very satisfied if I let my younger brother and sister get into college." Chen Fugui said with a smile.

"If Director Feng asked my family to support me and go to college, I would never pay this favor in my life. Anyway, I am willing to endure hardships and work, and even if I go back to the countryside, I can still make a fortune."

This is what he said in his heart.

Taking the college entrance exam is definitely a shortcut.

But for him, having such precious "wealth" is a detour.

"Do you understand? Sometimes what we call help is also carefully considered," said Feng Zhenye.

"Hey..., I just think it's a pity." Feng Haoyu muttered.

"Fugui, eat chicken legs first. You and Qianqian are one, and Haoyu can eat chicken breasts." Xu Fenglian greeted him enthusiastically.

"Then I'm not polite."

After saying that, Chen Fugui picked up the chicken leg and took a big bite.

This smell is really fragrant. He even wants to bite the chicken leg bones inside and savor it carefully.

I feel very accomplished in my heart, and the wealth in my dreams is really too precious.

When I heard the chemistry question, a lot of knowledge emerged in my mind.

Change to your former self?

Not to mention such a clever way to solve problems, even the most basic things can’t be understood.

This also gave him greater confidence in the development of the team.

"Something is wrong. Our teacher hasn't taught these things at the beginning. How do you understand?"

At this time, Feng Manqian said.
