Xue Xi tilted his head and thought for a while.

The piano player said that the host is not easy to provoke, and she inexplicably feels that this person cannot be added.

Thinking about this, the phone vibrated.

She quit her friends list and saw someone in the big group post a message.

Do not disturb: [Have you finished eating? 】

Xue Xi suddenly doubted Zhou Zhou's words.

How can it be difficult to get along with such a good owner?

She quit the chat box, opened the friend list, and after agreeing to the other party's friend request, she worries about the remarks.

What does the group leader do?

She thought of the chat content after joining the group. What the others said was that they learned from each other in their industry, and only the group owner was the group leader, and they could ask him for help.

Xue Xi had an idea in his heart, and filled in the remarks: Almighty boss.

After changing the remarks, she found that the other 19 people in the group responded to the questions neatly, just like elementary school students answering the teacher's questions after the boss spoke.

Ji Silin: [Just eaten. 】

Piano player: [Not yet. 】

Cen Bai: [After eating, in order to keep in shape, I only drank a glass of vegetable juice. 】

Feng Shengshen: [Eat it. 】

...

...

Xue Xi:?

The big brother's appeal is so strong, as if it were the leader of this group of people.

But she quickly denied her thoughts. Brother Si Lin is a free psychologist, and there is no leader...

Xue Xi followed at the end and replied: [Not yet. 】

Disturbance is prohibited: [Go to eat@学习]

Xue Xi:?

Why is Aite alone?

-

At the same time, "What's the identity of the little girl?" The group exploded.

Cen Bai: [The one who said four words in the group today, will four people in our group disappear tomorrow? Oh, I was so scared all of a sudden! 】

Zhou Zhou: [I feel that the painting style is wrong. Has WeChat been stolen? 】

Feng Xingshen: [From the perspective of the old man, the little girl who has a relationship with Jiaqun is not ordinary. I suddenly felt that I should not test her...Is it too late for me to withdraw my documents now? 】

Cen Bai: [What is the identity of the little girl? Does anyone dare to ask Ji Silin? 】

[Dare not]

【Dare to +1】

...

Xue family, on the table.

Today’s dinner was late, because Father Xue came home a little late.

During the meal, Xue Xi, who was already hungry, buried her head and ate quickly, and wanted to quickly go upstairs to study the questions, and then see the questions given to her by the math teacher.

At this moment, Liu Yiqiu suddenly said, "Mom, I remember Ruoruo likes to play the piano, right?"

When Mrs. Xue heard this, she suddenly smiled: "Yes, what's the matter?"

Liu Yiqiu replied: "Isn't this teacher Zhou Zhou coming to the home for the assessment next weekend? I thought it was better to take Ruoruo over and let her and Yaoyao take the assessment together."

Mrs. Xue's eyes lit up, "Yiqiu, are you serious? Are you afraid that she will take Yaoyao's place?"

Liu Yiqiu smiled: "Hazard, if it is Yanmei's daughter, and Yanmei is your daughter and Yaoyao's aunt, then Ruoruo and Yaoyao are sisters. They are both in the same family. It is the blessing of our Xue family to be admitted. !"

"atmosphere!"

Mrs. Xue praised.

Xue Yanmei is her youngest daughter. When she got married, the Xue family hadn't made a fortune, so her husband's family background was average, and Mrs. Xue felt very sorry for her.

Liu Yiqiu’s move made Mrs. Xue happy. She looked at Ye Li and said, "Ye Li, you should learn from your younger siblings! Look, this is what a mistress should have! Not wanting. Take all the awards as your own and don't give your sisters a chance!"

As she said, she glanced at Xue Xi, "Xue Xi, if you really treat Yaoyao as a sister, then you will withdraw from the physics competition!"

Xue Xi was eating ribs. She separated the bones from the meat first, and planned to swallow them before talking.

But Ye Li had already spoken: "Mom, why didn't Xue Yao withdraw from the piano assessment and just give the opportunity to Ruoruo?"

Mrs. Xue:? ?

Liu Yiqiu:? ?

Ye Li sat upright, and looked back at the old lady without a word.

The old lady pointed at her angrily, her hands trembling: "Okay, I have been married to our house for so many years, I didn't know you were so clever!"

Ye Li took a deep breath: "Mom, I'm just reasoning with you."

The old lady threw her chopsticks angrily, got up and left.

Liu Yiqiu asked: "Mom, don't you eat anymore?"

The old lady hum: "What to eat? I'm full of anger!"

-

Xue Xi ignored the episode during the meal. After eating, she went upstairs and finished reading the homework assigned by Lao Liu. She turned on the computer and downloaded the materials that the math teacher gave her.

When she took a look after opening it, she was stunned.

Because these things, coincidentally, are exactly the same as the ones on the yellowed roll paper she brought from her grandfather!

This should be a conjecture in mathematics.

What she has to do now is to prove that this conjecture is correct.

During this period of time, in addition to reviewing the questions, she would look at the manuscript of her grandfather. The proof of this conjecture in the manuscript has been carried out two-thirds. In the past month, she has inquired and learned through various materials, Has been pushed forward a bit.

It is still a while before this conjecture is proved.

So, she replied to the math teacher: [This question is a bit difficult. 】

Can it be difficult?

Feng Xingshen in Kyoto silently sighed, this is one of the unsolved puzzles in the world of mathematics!

He threw it to the girl just to test her math level.

If you can recognize this problem, it means that the girl is very knowledgeable in mathematics. After all, she is not at a certain level and she can't even touch the problem.

He hurriedly edited the message: [Yes, this subject is still unsolved. 】

Before the word was finished, the other party sent another message.

Study: [So, I need about a week to give an answer. 】

Feng Xingshen:? ?

confirmed.

The other party is an ordinary high school student, otherwise how could he answer this way?

To know how many mathematicians have devoted their whole life to this conjecture, this little girl is too ashamed.

However, with the protection of the group owner, he dared not say anything, and could only reply: [If you can't solve it, it's okay. 】

After sending the news, he returned to the "What's the identity of the little girl?" and announced the result:

Feng Xingshen: [It has been determined, pseudo boss, really related. 】

-

on Monday.

Xue Xi woke up very early, thinking about that conjecture, half an hour earlier than usual when he arrived at school.

When she reached the grocery store, she opened the curtain and walked directly in.

As soon as he entered the door, he was stunned when he saw the scene in front of him.

Xiang Huai should have just finished his morning exercises, and his body is full of sweat. He was carrying a T-shirt in both hands and was about to take it off. The hem of his clothes had been lifted, revealing a strong lower abdomen and waist.

Xue Xi was stunned.

A thought flashed in his mind: this person was thin when he was dressed, he did not expect that he would have flesh when he was undressed, and his abdominal muscles were well-proportioned, and his waist was thin but he looked strong...

Xiang Huai was also stunned when she entered the door so abruptly.

But when he saw that it was Xue Xihou, he raised his eyebrows and smiled suddenly. Instead of dropping his clothes, he raised his arm and took off the T-shirt...
