Sun Xiaochan has been very happy these two days. Not only can she drive her beloved cart and run around, but she can also eat delicious snacks anytime and anywhere, and there is someone to play with her at all times.

The little guy often laughs from ear to ear all day long, and it can be said to be: "I am happy here, but I don't want to worry about Shu."

Bai Xiangwen and Xu Liting no longer wanted to do business well. One did not go to the construction site to supervise the worker, and the other simply closed the store.

The couple devoted themselves to accompanying their granddaughter, allowing her to have fun and have fun.

I don’t have enough time to spend with my granddaughter during the day, so I would carry her to my room to tease her for a while before going to bed at night. When the little girl was so sleepy that she started to doze off, she was willing to call Bai Jingjing to take her away.

And whenever this happens, Bai Zhenzhen often comes out of her room to drink water or go to the bathroom.

Seeing her sister's cute niece who was sleepy with her eyes squinting in her arms, she would definitely poke her delicate face with her fingers, pinch her small nose and delicate lips.

Bai Jingjing was not worried that her sister would wake up her daughter, but instead took the initiative to care about her studies.

“How is the review?”

The college entrance examination time has been pushed back for a month due to the epidemic, which is undoubtedly good news for all fresh graduates who want to get a good exam.

"There is no problem with Chinese and foreign languages, but mathematics and physics are a bit difficult." Bai Zhenzhen answered truthfully.

The first sentence she looked confident, while the second sentence was a frown. It seemed that she was tortured by these two disciplines a lot.

Seeing that her sister was as skewed as hers, Bai Zhenzhen sighed. She was powerless in this kind of thing, maybe her current level was not as good as this girl!

Since she went to college, she has almost returned almost all of her knowledge in high school to her teachers, let alone now.

Bai Jingjing was very sure that she could not even recognize those symbols now.

But although she couldn't do it, she had a good teacher in her heart, so she pushed open the door and asked her husband who was typing: "Can you still do high school science questions?"

"Mathematics and Physics." Bai Zhenzhen added.

Seeing them like this, Sun Wu could not know his wife’s thoughts, so he answered confidently: “Don’t forget that your husband was the top scorer in science back then, so of course he would do it.”

After saying that, save the document and close the laptop.

Seeing that Sun Wu was willing to help, Bai Zhenzhen hurriedly said, "I'll take the test paper now."

=

Soon, Sun Wu would regret his big talk.

The mathematical question on the test paper is: "It is known that parabola, ellipse and hyperbola pass through point m(1,2), and they have a common focus on the x-axis. The axis of symmetry of the ellipse and hyperbola is the coordinate axis, and the fixed point of the parabola is the origin coordinate."

The first question is to find the equation of these three curves. This sister-in-law has already solved it by herself, so he doesn't need to worry too much.

The second question is: "It is known that the straight line l passes through point p(3,0) and crosses the parabola at points a and b. Is there a straight line l1 perpendicular to the x-axis and the chord length obtained by a circle with a diameter of ap as a fixed value? If it exists, find the equation of l1; if it does not exist, please explain the reason."

When I saw the second question, Sun Wu's first reaction, the equation of the straight line l1 certainly existed, which is his past experience.

Then we need to find the equation of the straight line l1. Sun Wu still has a little impression of this type of problem. He took the pen from Bai Zhenzhen and started to solve it while explaining it.

"You want this...you should..."

Sun Wu looked at the figure on the draft paper and looked at the topic again, and suddenly got stuck.

He suddenly discovered a very serious problem. He seemed familiar with this set of questions, but that was only a past time.

Nowadays, not only are they in the dim lights, but they are also disdainful to look back at him.

Since he couldn't see the other person's true face clearly, he naturally could not describe her. He could only look at the empty and sad topic, hurting others and never having a young man again.

When Bai Zhenzhen saw her brother-in-law's hesitant appearance, she immediately realized that he didn't know either.

However, thinking that the other party relies on literature to make a living, this seems to be an extremely normal thing, so I can't be much disappointed.

In order not to make Sun Wu feel embarrassed, she had to slap her forehead hard and pretend to realize it: "I heard from my brother-in-law that I immediately became enlightened and knew how to answer it."

After saying that, he picked up the test paper and prepared to get up and leave.

But Sun Wu could let her leave so easily, so that his reputation would be ruined by a mere math problem, so he forced the test paper to the desk, and said in a pleading voice: "Give me another five minutes, and I will definitely be able to answer it."

Seeing that Sun Wu was like this, Bai Zhenzhen had to agree.

What about Bai Jingjing? She lay on the bed, holding her mobile phone to start cleaning the book review area of ​​"The Demon Hunter".

People are popular and have many troubles, so are books.

Since "The Witcher" became popular, there have been a constant stream of authors coming to the book review area to advertise, and there are even people asking for rewards one by one under the posts of the leader.

In addition to these, there are also people who deliberately blackmail and those who are "intern" who come to scold the latest plot with the title of "intern".

Originally, Zhou Mei, the operation officer, did this kind of thing, but since she started writing novels, she has the goal of earning one million a month, and her mind is almost all about her novels, and she is not as concerned about this job as before.

In fact, this is not true. The reason why Zhou Mei was conscientious before was not because she had a good relationship with Sun Wu, but because she enjoyed the fun of being an operation officer.

Now that her novels are not only successfully signed, but also many book friends encourage her, she naturally no longer has the vanity to be greedy for.

If you are the chief supervisor of others, you will not be happy to be the emperor.

Seeing that the last message from the operation officer Wu Meiniang was "0:13 on March 31, 2020", Bai Jingjing frowned and muttered in a low voice.

"What's going on with Zhou Mei? Do you still want to do it?"

He looked up and wanted to discuss with his husband that he could fire his former colleague next month. Seeing him biting his pen cap and frowning, he had to temporarily put this matter in his heart and not to cause trouble for him.

Sun Wu picked up the pen and couldn't make it.

Bai Zhenzhen felt sorry for her beloved pen on the other side, but her brother-in-law bitten it.

While looking down at the time on the phone, he was worried in his heart whether he should remind him. Fifteen minutes have passed.

But when she thought that the other party was thinking hard, she felt embarrassed to interrupt her thinking, so she had to continue to lower her head and chat with her classmates in the group.

"I'm really not used to using Apple 11promax. I would have known that I wouldn't have asked my sister to buy it for me, and it would have wasted more than 10,000 yuan."

When Bai Zhenzhen said this, she completely forgot the ordinary comment she posted on her Moments the day before yesterday and the apple logo she was thinking about.

Bai Jingjing noticed that her sister had a smile on her lips, and knew that she was lazy, so she complained to Sun Wu: "Forget it, don't show off for me, let this girl think about it myself."

Hearing the dissatisfaction in his wife's tone, Sun Wu turned his head and glanced at Bai Zhenzhen and immediately understood the reason.

But he didn't want to give up, so he said to the playful sister-in-law unwillingly: "Go and bring your math book. Although your brother-in-law hasn't done the questions for a long time and has a strange idea of ​​solving problems, his learning method is still there and he can teach you how to review."

At this point, he didn't ask to overcome this set of problems anymore. He just wanted to tell them an undisputed fact, that is:

"I, Sun Wu, is really the top scorer in science. I only lost 27 points in the college entrance examination for comprehensive science and mathematics."

Bai Jingjing also agreed with her husband's words and said to Bai Zhenzhen: "Your brother-in-law took the college entrance examination in mathematics at 145 and science 278. There must be a learning method. Please let him teach you."

Bai Zhenzhen didn't want to waste her time anymore, but since her own sister said so, she had to reluctantly agree.

Then she witnessed what is the top scorer in science! What is the genius!

After translating, she felt that her teacher was not as good as this brother-in-law. She could explain all the key points of this page by just looking at the book, and she understood it as soon as she heard it.

Sun Wu didn't expect that he could be so powerful. Although he knew what was going on, he still had to teach Bai Zhenzhen:

"I have been able to reach this point by studying hard. There were 12 more powerful college entrance examinations than me back then. You don't have to envy me, just work hard on your own."

"Know."

Bai Zhenzhen nodded vigorously and buried her head in hard work. In a blink of an eye, it was almost dawn.

Sun Wu stood up and pulled the curtains hard to both sides, and the star hung high in the distant eastern sky, lonely and dazzling.
