Did you apply to Peking University for you to go to Tsinghua University?

Chapter 031 ∠Boyfriend

"Yuan Qian is my mother."

Now that he decided to say it, there was nothing to hide, so Yu Chao went straight and threw the bomb.

Because Lu Chuan was too shocked, he subconsciously asked back: "Who do you say is your mother?"

"Yuan Qian." Yu Chao replied.

Yuan Qian is 33 this year and Yu Chao is sixteen, so Yuan Qian's seventeen is the birth of Yu Chao.

And I never heard anyone say that Yuan Qian is married...

After the words Yu Chao landed, there was a long silence on both ends of the phone.

"Why did you tell me this?" Lu Chuan asked.

why......

In fact, Yu Chao didn't know why.

"Have you finished eating?" Yu Chao changed the subject in a timely manner.

"It's over." Lu Chuan replied, and then he seemed to think of something, "Then Yuan Lide...?"

It might be because of the topic of discussion, or something else, in short, when Yu Xiang sat up from the sofa, he felt that he was pulled back to reality.

Somewhat cold.

The inexplicably warm atmosphere just now seemed to be just his imagination that he almost fell asleep.

He put on his slippers: "My grandfather."

"Oh." Lu Chuan's voice was calm, but he was actually shocked inside.

It was rumored among classmates before that Yuan Qian was Yuan Lide's daughter, but now Yuan Lide's grandson has also been found, which is Yu Chao.

Yu Chao got up to get a cup of hot water, and felt that he who had thrown this blockbuster needed to explain a few words.

"Yuan Qian was the seventeenth child of me. She was in her third year of high school, and she and Yuan Lide felt ashamed..." Yu Chao was picking up water, and he paused when he said this, "So I don't want to admit it."

"I don't have a father, so the surname 'Yu' was invented blindly." Yu Chao continued.

"En." Lu Chuan responded, and unscrewed the Coke in hand again.

He didn't know whether to ask a few more questions or end the topic.

The good thing is that Chao seems to have just casually mentioned these two sentences, and has no intention of continuing the conversation for a long time.

"Do your homework after eating." Yu Chao said on the other end of the phone.

A mini bottle of Pepsi is only about 200ml. After drinking it in a few sips, Lu Chuan threw the bottle into the trash basket at his feet, stood up from the high chair, and walked to the living room with his slippers on, thinking about the night. Have you eaten?

During dinner, the third child came to call him and A Wu. He wanted to ask Yu Chao to go with him, but he went out to use the toilet and came back to find that Yu Chao was no longer there.

I don't know if Yu Chao has eaten.

Lu Chuan walked to the sofa in the living room, picked up his schoolbag twice, and found that he didn't bring back the exercise book.

He has always been able to copy as much as he can during evening self-study, and if he can't finish copying, he will be a failure. He rarely takes homework home to do.

Lu Chuan helped the earphones hanging on his ears, and said calmly, "I didn't bring homework back."

"Then make it with an acting herb." Yu Chao was merciless.

Lu Chuan smiled, turned around and went back to the house to look for a notebook: "Does it need to be so strict?"

When Lu Chuan was walking towards the bedroom, Yu Chao happened to be returning to the bedroom.

The desk facing the bedroom is at the end of the bed, the room is large, there is a distance between the end of the bed and the desk, a gray carpet is laid, and a lazy sofa of the same color is placed on the carpet.

Yu Chao turned his mobile phone into hands-free and threw it on the bed, while he picked up the previous Olympiad and held it on the sofa again.

Considering that Lu Chuan probably did his homework "seriously" for the first time at this time, Yu Chao thought about it, and "indulged" him a little as he said.

"A few questions in mathematics and physics must be done. Memorize English words from the first unit. I will recite a quarter of it today, and I will read biology and chemistry tomorrow." Yu Chao put on glasses, and his whole body was sicker than before. Sometimes it looks more energetic.

Lu Chuan pulled out the chair, sat in front of the table, flipped through the notebook he just took out from the crack of the table, and smiled kindly: "Okay."

In order to know Lu Chuan’s level, from basic to very difficult questions, Yu Chao circled him one or two questions at each stage, a total of ten questions, with choices and major questions. According to Yu Chao’s level, it takes two to 10 minutes. Done.

Lu Chuan used the tablet to save the picture that Yu Chao had just sent, clicked to open it, zoomed in, and started to read the question while turning the pen.

"As shown in the figure, in an equilateral triangle, AB=a, o is the center of the triangle...Why is o the center of the triangle?"

"Because it was set by the title." Yu Chao circled the conditions given by the title on the book with a black pen, "abcde, set whatever you want for the title."

"Oh." Lu Chuan nodded, and the spinning pen fell on the table with a soft "pop".

Lu Chuan picked up the pen and turned it around twice: "Then I think it's okay to set it as p."

"up to you."

"Row."

"The straight line passing through O intersects AB with M, and intersects AC with N, please..." Lu Chuan read and changed the letters.

He crossed out the letter B and changed it to a Y, and changed the letter Q to an L.

This question is simple and a basic question, just use the law of sines to invert the formula twice.

But Lu Chuan is not familiar with some theorems and formulas, and only stays at the stage of "remembering" and "recognizing". He searched for the formulas, drew and wrote for 10 minutes before he could solve this problem.

"I'm done."

"Yeah." Yu Chao rubbed his wrists, took off his glasses, pinched his nasal bone, "Send it to me for a look."

Lu Chuan took a photo with the tablet and passed it on to Yu Chao.

From the picture, you can vaguely see the outline of Lu Chuan's desk. There are several dinosaur figures on top of the light yellow textured wooden tabletop. In the middle of the picture is a pure white horizontal grid book, on which the whole problem-solving is written in black pen. process.

The writing is clean, the handwriting is neat, and the handwriting is also very beautiful. It is not at all like a student who is absent from class all day long and can write words.

Yu Chao looked down at the problem-solving process on the picture.

The front is all normal, but the last sentence...

[Solution: Because O is the center of the equilateral triangle ABC, ∴ AO=3a...

...Finally, sin∠NPY=LC·YC/2 is obtained. 】

∠Boyfriend=Lu Chuan X Yu Chao?

The author has something to say:

Lu Chuan: Continue to confess your love every day
