The Magic Trading System

Li Lingling studied in the Department of economics. It's very difficult for her to master the courses of the Department of economics, because it involves many interdisciplinary subjects. She needs students to have strong learning ability and understanding ability, and then she can master the knowledge.

The course of information economics is also very difficult because it uses a lot of advanced mathematical knowledge.

Even for excellent students, it is a difficult point.

Therefore, Li Lingling said that Zheng Hao could grasp the essence of this course after a brief look at information economics. Wang Yanhong and Zhu Haiping didn't believe it.

"Chi! Li Lingling, are you teasing us? If Zheng Hao has never been in touch with information economics before, he can't simply turn over this book and have a thorough understanding! I can teach you on the spot and let you fully understand. This is a myth Wang Yanhong didn't believe what Li Lingling said at all and said sarcastically.

"Li Lingling, are you sure you have mastered the course of information economics well?" Zhu Haiping asked with a sneer on her lips.

"I'm sure." Li Lingling said wrongly.

She didn't understand why her two roommates didn't believe in herself.

"Good! I dare to say that you have a good grasp of information economics, so I'll give you a question, and you can help me solve it. " Zhu Haiping said.

"Well, you can give me a question." Li Lingling is also very angry in her heart. These two roommates always look down on her. Li Lingling said, this time, I must give a good performance and shock you!

It's nothing for you to despise me.

But you can't look down on Zheng Hao!

What qualifications do you have to look down on Zheng hao?

In my heart, you do not deserve to give Zheng Hao shoes!

Zhu Haiping looked through the book of information economics, and then gave Li Lingling a title of the most difficult knowledge point in this course.

If put before, Li Lingling can't even solve this problem.

Therefore, after hearing Zhu Haiping give Li Lingling such a question, Wang Yanhong looked at Li Lingling with a bit of schadenfreude and said, "Lingling, you are finished. This question is so difficult, even I can't do it! I don't think it's good for you to understand the meaning of this question, not to mention it

Li Lingling took a deep breath and looked at the topic carefully.

Originally, she was still a little nervous. She was afraid that she would not really answer. In that case, Zheng Hao's people would be lost. After all, what she said just now was full.

However, after reading the title, Li Lingling relaxed her whole life.

She found that the problem should not be too simple.

"Zhu Haiping, you look down on people, don't you? It's amazing to say that I can understand the meaning of this question. If I can do it, what can I do? " Li Lingling asked calmly.

Zhu Haiping sneered: "if you can work out this problem, I'll write my surname Zhu upside down in the future!"

"Ha ha! Good! Zhu Haiping, you mean what you say, don't you? " Li Lingling laughed.

"Absolutely! one word is as heavy as nine tripods! Every word that falls to the ground can make a hole! " Zhu Haiping said with a powerful wave.

"Good! Then I'll show you the solution to this problem now! " Li Lingling is also holding a stomach of gas, she picked up the pen, began to "Shua Shua" to solve the problem on a performance herb.

She wrote very fast, but in a few minutes, she solved the problem of information economics.

After the calculation, Li Lingling put down her pen and looked at Wang Yanhong, who wrote the question, and said, "Wang Yanhong, I have finished the answer. Please see if my answer is correct."

"Well, let me see." Wang Yanhong said.

She watched Li Lingling answer so quickly and wrote a big answer.

Wang Yanhong murmured in her heart. She said, looking at her, did she really solve the problem? This shouldn't be ah, class girls in private to Li Lingling gave a nickname: "silly white sweet.".

Many girls who have been in contact with Li Lingling think that Li Lingling is a bit stupid and not smart enough. Although she is practical in her study, she is very slow in her study. After the teacher has finished talking about a lot of knowledge, she is still confused and confused.

Wang Yanhong took Li Lingling's answer in her hand and looked at it carefully. When she saw it, she was very surprised: is it true? Li Lingling's answer is actually very correct. Every step is concise and clear, which is pleasing to the eye. Of course, the final answer is also completely correct.

Wang Yanhong looked up at Li Lingling, her face full of surprise.

"How about Wang Yanhong? Is her answer correct?" When Zhu Haiping saw the expression on Wang Yanhong's face, she just clattered.

"Quite right." Wang Yanhong said.

"Ah? Why? How could she do such a difficult question right? It's incredible. " Zhu Haiping said in a startled voice."Li Lingling, you said, have you just seen this problem before, so you can do it?" Zhu Haiping looks at Zheng Hao and asks.

"No, I haven't seen this problem before, but I have mastered this knowledge very well! Zhu Haiping, I hope you can abide by the oath you just made! As you said, as long as I answer this question correctly, you will write your surname upside down in the future. " Li Lingling sneered.

Since Zhu Haiping is not polite to herself, she has nothing to be polite to.

"Ha ha! With your intelligence, you can't solve this problem! Therefore, it is absolutely impossible to keep the oath I just said. " Zhu Haiping said.

Li Lingling almost lost her nose when she heard that.

This girl is so hateful.

It's insulting.

"Zhu Haiping, seriously, I blush for you. What I said is not a word. What did I just say to me? If I drop a word on the ground, it will make a hole! Don't you think you're funny? Where's your credibility? Do you know that it will ruin your credit Li Lingling said with a sneer.

"If you can solve another problem of information economics, I will believe that you really master the course of information economics, and I will write my last name upside down." Zhu Haiping said.

She's playing a rogue.

Li Lingling took a deep breath and said, "I can't bear it! I'd like to see how Zhu Haiping can play rogue next! "

"Yes! I promise you! How about another problem of information economics?! However, I ask Wang Yanhong to answer this question! " Li Lingling said.
