Chapter 449 (1/2)

Outside the study, Zhan beiheng's low footsteps came.

Lin Jiangxia is flustered. She is busy turning over the book in front of her.

Even the first third is just swallowing, and the last two-thirds is just turning a book.

Just turned it over and closed it.

The study door was opened.

Zhan beiheng stood there with a ruler in his hand. The external light came from his back and plated a layer of color on the outline of his body. He looked like an envoy from the region.

Lin Jiangxia's heart couldn't stop shaking.

But her reaction was quick. She immediately showed a smiling face, tilted her head, slightly charming, squinted at Zhan beiheng and said, ”brother Zhan, I've finished reading it, isn't it very good?”

Even if brother Zhan is so cruel, isn't there such a saying? Reach out and don't hit the smiling face!

But obviously, Zhan beiheng didn't change her look because of her smile.

Expressionless, he approached the desk, pulled the book in front of her and opened it.

Does that mean to check?

Lin Jiangxia couldn't help swallowing saliva.

Silently praying in my heart, I can't turn to the back, I can't turn to the back

But about this time, even God has gone to sleep.

She longed for brother Zhan to turn the back half of the book, and then said, ”answer me, the definition of opportunity cost.”

What the hell? What is the definition of opportunity? It sounds completely strange words. What should I do!

Lin Jiangxia's face was dull and looked a little cute.

Can be lovely, and can not dispel the cold look on Zhan beiheng's cheek.

”Brother Zhan, if you finish reading such a whole book in such a short time, no one can remember every definition in the book!” After much deliberation, she decided to argue.

To be a man, we always have to be reasonable!

”Hands out!” Zhan beiheng's face turned sharp and his voice was cold.

”Brother Zhan, you can't be so unreasonable!” She hid her hands behind her and looked at him in horror: ”even brother Zhan can't remember all the definitions in the book in such a short time!”

”I didn't let you remember.” As if to make her willing to be beaten, he opened his mouth: ”the concept of opportunity cost does not exist in this book.”

”Ah!” Lin Jiangxia's reaction was quick. He clapped his hand and said, ”I said how can this word be so strange? Yes, yes, this book doesn't mention it at all!”

Zhan beiheng outlined the corners of his mouth and looked evil: ”did the second half of this book talk about the concept of producer surplus?”

I don't know if I have! The last two-thirds, she hasn't read at all, okay?

Shen: Well, the argument failed.

Life is so hard.

”Reach out!” He said again in a hurry.

Forget it, you should stand firm when you are beaten. It's just ten hand boards. What's the big deal? You haven't been beaten!

Shen Lin and Jiang Xia straightened their palms. The delicate palms were so straight in front of Zhan beiheng.

At the same time, he frowned gently, his lips pursed slightly, and looked pitiful.

Brother Zhan, no matter how vicious he is, he won't kill such a lovely girl!

She always has this unrealistic fantasy in her heart.

Zhan beiheng seems to regard this process as the implementation of family law, and completely adheres to a posture of law.

Pop!

The ruler lifted high and fell heavily.

”Ouch!” She screamed again.
