"Bo Cheng, you wrote very fast this time. You did some high school questions right, especially some Olympic math questions. I was surprised that you were so right."

Bo Cheng was not at all pleased with the teacher's praise. He frowned and locked his eyes on Bai Sang's test paper.

Bai sang looked up at the teacher.

The head teacher felt his sight, coughed and took another test paper: "Bai sang, you've done everything right, even Mathematical Olympiad has full marks."

Bai sang exhaled and smiled.

Bo Cheng sat decadent on the chair, hung his head and looked as if he had been hit.

He quickly got up and grabbed Bai sang from the teacher's hand. He looked down at the answer seriously.

Bai Sang also brought his test paper.

After reading it, I gave a tut tut.

Fortunately, his core is not an ordinary junior high school student, otherwise he will certainly lose.

Look at the answer above. It's so well written.

Later, even if he couldn't, he wrote out the analytical formula, only missing an answer.

——A little pervert.

After reading all the answers over there, Bo Cheng found that Bai sang not only wrote the correct answers, but also answered them perfectly.

After reading the answers to the following Mathematical Olympiad questions, he suddenly realized that he could answer them like this.

He gave in.

Put the test paper on the table: "I lost." looked up at Bai sang, "you won, University --"

When Bai Sang was about to say something, he quickly caught the man and ran out.

"Teacher, let's go first."

The head teacher still wants to leave someone to say a few words. I don't know if the words have not been said yet. The two students have run away.

Bo Cheng was pulled by her, and his face was very unhappy. He came to the corner where no one was there.

"This is our little secret. We can't tell anyone else."

After running for two steps, she has white and ruddy cheeks. The white mulberry in the world is not bad. Her advantage is that her skin is white. As the saying goes, one white covers a thousand ugly. She is also a little beautiful.

The broken hair in front of his forehead stuck to his cheek and fell into Bo Cheng's eyes. He felt that the girl in front of him was not very ugly.

Although it is not as good-looking as other girls he has seen, it also has characteristics.

For example, they have round eyes, white cheeks and red lips.

Together, I don't hate myself.

Bo Cheng found that his sight was taken off track and quickly took it back. "A gentleman's word is irretrievable. I'll abide by it if I promise you."

"Well, it's still early. We're only junior high school students and we have to go to college."

Bai sang looked at his stubborn temper and smiled softly.

"Yes." Bo Cheng glanced over: "but I want to add an additional condition."

"What additional conditions?" She was nervous.

"You can maintain your study, and you have to go to the same school as me in junior high school and senior high school. If you can't, this oath doesn't count."

Bai sang thought it was an accessory condition. He didn't hesitate to nod: "OK!"

The condition is simple.

Bo Cheng nodded and went to other places.

"Where are you going?" Bai sang saw him going and followed him.

"What does it matter to you where I go? It's over. I'm going home."

Bai Sang was speechless.

It's not very good to forget the relationship between them for a while.

She has to hurry to his class.

Seeing someone leave, he turned and returned to the head teacher's office.

Say what you think.

"This is simple. If you can maintain the results you have shown me in the midterm exam, you can turn it around."

Bai Sang was certainly happy to get a reply.
