"Oh, no, it should be …" Shen Xinyu scratched his forehead a little indecisive again.

"Xia dynasty"
The man was a little hoarse and intoxicated, and his voice finally fell from her head.
Shen Xinyu blushed "…"
I don’t know if it was because I drank a little wine tonight or because the girl’s expression in front of me pleased him. Tang Shiyan pulled up a chair from the side to sit down.
Pull out a pure white roll from her hand. "None of this?"
Shen Xinyu looked over and nodded. "It’s too difficult."
Those symbols and formulas are like the sky.
This time, the man didn’t speak, with a roll in one hand and a desk in the other, as if thinking about something.
Maybe he will give her a lecture?
Section 15
I heard that he is twenty years old this year.
After a while, the man drew a textbook from the table and handed it to her.
"What formula?"
Shen Xinyu took it a little stupid.
Tang Shiyan glanced at her "fifteen-page derivative function"
“……”
Shen Xinyu was suspicious and looked up in surprise.
"What’s the matter?" The man seems to have a pair of eyes on his head with his head down.
"It’s okay. Do you have to write all these formulas?"
Shen Xinyu immediately shook his head and then asked
"hmm"
Tang Shiyan raised my hand and took a pen. Her arm grazed her nose and there was a faint and clean sandalwood fragrance.
Shen Xinyu "…"
Just as she expected, a moment later, the man really picked up her formula paper and told her the topic, not together, but one formula after another.
First, let her memorize a formula, then solve the problem according to this simple formula, and then change the order, change the question type and extend it.
All night, my ears were full of men’s deep and sexy voices. I didn’t expect him to remember it so clearly after ten years of college entrance examination …
Tang Shiyan didn’t know how he came to be interested today, but he patiently gave a little girl a guidance topic. After a while, he raised his wrist and looked at it. "I’ll go out for a while if I’m left alone."
"good"
Shen Xinyu nodded obediently.
Tang Shiyan pulled two necklines and felt a little uncomfortable.
The servant has put the tea on the table, and the housekeeper came over and said, "Mr. Tang’s Shenyang contract has been sent."
Tang Shiyan took the cup and drank two times and nodded "Take care of it."
The sound is a little hoarse
Before the housekeeper, she added some water to the teapot. "Aunt Wu just told me that Lu Xiaotian will come out every Sunday from 9: 00 to 11: 00. Can you watch this? Is there a place? "
Tang Shiyan glanced at him. "Let him come here."
Don’t. He doesn’t know their little thoughts.
The housekeeper nodded with a smile.
Sure enough, nothing can be concealed from Mr. Tang. He recommended Lu Xiaotian. One is that the child is really excellent, and the other is to let Aunt Wu see more.
