But what love can a gold master buy?

An hour later, Wei Li opened the bedroom door: "Go in and copy."

"Yeah!" Shen Tinglan immediately jumped up from the sofa, jumped to the door of the bedroom in a few steps, and pointed to the coffee table in the living room before entering the door, "I ordered some food, you can eat and rest for a while, watch TV or something It's all right."

Wei Li nodded, leaned over and picked up the remote control to turn on the TV, and then sat down on the sofa in the living room.

On the coffee table in front of him, there were indeed some snacks such as chicken wings and anchovy shrimp scattered here and there, basically untouched, obviously bought specially to reward him.He put on disposable gloves, grabbed a piece of egg tart and put it in his mouth - most of the lunch went into Shen Tinglan's stomach. As a chef, he worked continuously for an hour, only ate two small pancakes and drank a cup of tea , is indeed not enough.

Shen Tinglan was having fun in the bedroom.

Wei Li's handwriting is correct and clear, and the calculation process is complete. It looks more reliable than Wang Han, and after comparing the answers of the two sides, there are seven questions with different answers!

After copying in one breath, he called a flash delivery and sent the homework to the school.

This series of things was over, he looked back to the living room, the TV had been turned off, and the snack box on the table was empty, Wei Lizheng took off his gloves and put all the torn wrapping papers in, looking like he was about to tidy up.

Seeing this, Shen Tinglan had a flash of inspiration. He went back to the room and took the manuscript paper and other things, brought them to the coffee table in the living room, and then waved to Wei Li: "Come on, give me the lecture topic."

Wei Li nodded slightly, cleaned his hands with a wet towel, and then walked back to the sofa.He was about to sit next to Shen Tinglan when he saw the other side slap his thigh: "Come, sit here."

Wei Li hesitated for a moment, but didn't take a step: "I'm a little heavy."

Shen Tinglan put her spread legs together slightly, and pulled the person over: "It's okay, I just sat in yours, and you come to sit in mine too."

Wei Li was caught off guard and fell onto his lap. Seeing that the soft sofa sank a lot, he asked, "Are you all right?"

Shen Tinglan couldn't say that he used to sit on his lap without any problems, so he smiled and tickled his fingers towards the coffee table, signaling him to bring books and other things: "Two people read the same book at the same time, this distance is the best."

Since he said so, Wei Li had no choice but to give him a lecture in this ambiguous posture.

"The year corresponding to this table is 0. The initial value does not need to be multiplied by the cost of capital, but by the equivalent coefficient. The net cash flow of each year is multiplied by the equivalent coefficient and then multiplied by PVIF10%. All these are added together, which is The net present value of the project…”

Shen Tinglan listened "hmmm", as if she was very serious, but one hand had already penetrated into Wei Li's T-shirt, touching his beautifully contoured abdominal muscles.

Shen Tinglan's gentle palm was like a restless animal, which made Wei Li feel a little itchy and uncomfortable.He couldn't stop it directly, so he had to say: "Take your mobile phone and do the math yourself."

Shen Tinglan knew what was going on in his mind, but wanted to play tricks even more. He fumbled around with his hands, and leaned his head against the other's chest: "I will, just keep talking."

"This problem, the calculation is over here." Wei Li's chin was scratched by his hair, and it itched from time to time, and it itched again, which was very uncomfortable.Barely enduring two itches, he said, "Then answer the question, is this project worth investing in?"

"Investment..." Shen Tinglan finally allocated part of his attention to the topic.After watching for a while, he didn't see why, but he didn't feel ashamed, "I don't know, just tell me."

"It's up to you to figure out the answer first," Wei Li grabbed Shen Tinglan's troubled hand, took it out of his clothes, and put it on his lap, with a faint smile on his lips, " I can explain."

Shen Tinglan was feeling excited. Although he knew that this had nothing to do with step-by-step progress, he was still quite upset when he was interrupted.Just as he was about to say something, there was heat in his ear, and Wei Li whispered, "Obviously you asked me to talk about the topic, why are you not serious?"

He just wanted to try his best to persuade Shen Tinglan, because he felt that the other party was not so shameless that he could not believe what he said, but he didn't know that Shen Tinglan's ears were his weakness. As long as someone came close to talk, he would be sore from his ears to his whole body. , just like electricity.

What's more, Wei Li's voice is completely subwoofer, with a kind of hoarse tenderness, this soft reproach is enough to make his nerve endings spark.

Seeing that he suddenly stopped moving, Wei Li thought that his words had taken effect, so he continued while the iron was hot: "When I was a junior in junior high school, I was a tutor, and the price was 150 yuan an hour. After ten years of inflation, this figure has more than doubled. Now it’s cheap to teach you, you can’t let me waste my time, can you?”

After he finished speaking in a low voice, he stuffed the phone into Shen Tinglan's hand, and the latter opened his mouth, but fell limply in his arms, giggling.

Seeing him laughing suddenly, Wei Li became vigilant again, closed his mouth and waited quietly.

After a while, Shen Tinglan seemed to have had enough of laughing, and raised his head to look at him, with a few broken tears on his eyelashes: "During the time of the lesson, I will count you three hundred more, but after I learn , you want to reward me."

After finishing speaking, without waiting for Wei Li to answer, he clicked on the calculator on his phone, and quickly calculated a series of numbers: "10 yuan. Then?"

Wei Li pointed to the examples in the book and showed him: "The net present value is greater than 0, the project is worth investing in."

"Remember," Shen Tinglan drew a circle on that page, then turned to Wei Li with a meaningful smile, "reward."

However, Wei Li didn't meet his gaze, and raised his hand to turn the pages of the book: "You do a similar question first, and see if you really know it."

"Hey, okay." Shen Tinglan saw that the question was not too difficult, so he was more willing to try. After a while, he said, "It's done, and the net present value is less than zero. This project is not worth investing in."

"The answer is correct." Wei Li turned on the timer on his phone, "You have seven seconds to reward, let's start."

Shen Tinglan didn't expect him to repeat the old trick, and opened his eyes wide: "7 seconds is too short, isn't it?"

"Because this is an easy question." Wei Li spoke quickly, "There are six seconds left, no waiting."

Shen Tinglan quickly stretched out his hand: "The time given for that problem should be longer! Not seconds, but minutes!"

"Okay." Wei Li stared at the countdown number on the phone, "Okay, time is up."

Shen Tinglan withdrew her hand in a still unsatisfied way: "Come on, the second question."

"This question is to calculate marginal cost. The formula is on this page."

After listening to the analysis, Shen Tinglan clicked on the calculator and quickly solved the problem, and then hurriedly asked for confirmation: "How is it? Am I doing it right?"

"correct."

Wei Li started to adjust the timer, but Shen Tinglan said before pressing start, "Wait!"

"what happened?"

Shen Tinglan pointed to the pitiful single-digit number on the phone: "This question is a little more difficult than before, please add a little more time, at least it needs a double-digit number!"

"Is it difficult? But you spent less time than the first question." Wei Li looked at his face that was about to change, and changed the topic, "But because you are more serious, I will promote you to the first question." Double digits - 10 seconds."

"!?"

When Shen Tinglan was writing the third question, he racked his brains to calculate, and found that there was no room for Wei Li to set the rules for him—the shorter the time to do the question, the simpler the question, and the shorter the time to enjoy it.If you want to enjoy it for a long time, you have to do difficult problems, but if you do difficult problems, the waiting time will be longer!

[The author has something to say: blindly play eight small theaters.

Shen Tinglan: Careless.Ten is actually a two-digit number. (`Д%3F|

Wei Li: Let me see how difficult you can do. 】
