"The trapezoid area formula is the upper bottom plus the bottom multiplied by the height divided by the second. Do you understand? "Because there's a rectangle after the next match, do you know …"

"Two is because of the vertical line. Look, isn't it two triangles …"

"Motherf * cker, my god …"

After speaking for a while, I realized that Zhang Kefan's foundation was truly not that good. Even the most basic trapezoid formula can't be understood, but in the end, she actually forced my Sichuan words out.

After talking to her for a while, I realized that I was even more tired than she was. If the air conditioner hadn't been on in the room, I felt like I could have been sweating because of her.

She was amused by my last phrase, Sichuan, and I was worried that her results would show during the final exam, making the Sister Kexuan unhappy. After all, there would be a parents' meeting at that time. Teacher Hou was a typical teacher who liked good grades and hated bad grades.

Just based on Zhang Kefan's results in another month, she would definitely be called upon and criticized by Hou Ge in the clan elders' meeting after the exam. At that time, Zhang Kefan's lies would break by themselves. I can't imagine how sad Sister Kexuan would be.

Why are you laughing? I'm too lazy to speak Mandarin for you right now, but you already said that you want me to help you with your studies. At the very least, you have to listen to me when I'm learning.

As I said that, Zhang Kefan started off laughing while trying to hold back her laughter, all the way until she started laughing out loud.

I was so angry with her that I couldn't say anything. I had to change my mouth again, and I waited for her to finish laughing before I went back to the topic.

The rest of the month passed by in this manner for the most part. Zhang Kefan's grades, which were made use of by me every night, actually soared among the papers one by one.

Teacher Hou, who had always been uninterested in her, also praised her in his class for the first time. The students who had always played with her and did not have a good score all looked at her with very surprised eyes.

However, she attributed all this to her own efforts, not mentioning the fact that I had helped her with her studies, but I was used to it, and it might have seemed strange to me if she had mentioned it.

Aside from helping her learn, I would come home late almost every day. I would go to Lao Xu's place to see if he had found anything, but every time, I would go there with hopes in my heart. However, what Lao Xu had said to me was always "Don't worry, I'm looking into it right now."

I could tell from Lao Xu's messy bookshelf that he was really searching for something. It was only then that I realized that I had urged him too hard.

The word on the blackboard inside the classroom was, "One day before the exam."

Teacher Hou said that we will take a day off before the exam. He told us to adjust ourselves and come to the school for the exam on the last day.

It was the same as before. After packing my bag, I was prepared to leave, but now, it could even be said to be the time when my eyebrows are burning with anger. The most terrifying thing is that Lao Xu still did not manage to find out anything.

"Lao Xu! Did you find out? We have to take the exam the day after tomorrow. "

"Don't worry, I just found it, but I'm not too sure. I have to check it out first." Hearing my shouts, Lao Xu put on his reading glasses and ran out of the room with a book in his hand.

"Go take a look?" Where to look? It can't be my home, right? " Honestly speaking, I was in a rather difficult situation, because Sister Kexuan and Zhang Kefan were at home together after all, and I didn't tell them what this was about. With Zhang Kefan's personality, if she knew that it was because she was sick, she would definitely not let Lao Xu in to take a look.

"I'm not going to your house, I'm going to lose your neighborhood, or I'm going to have to go downstairs."

"Then when are you going to go?" I asked him.

Lao Xu took off his glasses and put it in his pocket, then said to me: "You stinking brat, weren't you in a hurry the whole day? "Then let's go!"

"Got it!"

After saying that, Lao Xu immediately closed the door and took the book.

"What are you doing with that book?"

"I am a paper maker, not a feng shui master. Do you think I am good at marking? For the past month I've had to go and see if it fits the book. "

I know it all at once, but did Lao Xu start researching feng shui in this one month?

Wait a minute, Feng Shui? It was only then that I realized what had happened and immediately asked Lao Xu, "Do you think that there's a problem with my sister's Feng Shui?"

"I don't think so. I've checked for the past month, and excluding ghosts, that would mean Feng Shui's problem. There won't be a third reason. And the thing I've just checked on also happens to be related to Feng Shui."

"What the hell is this Feng Shui?" As soon as I mentioned Feng Shui, I remembered the "Golden Carp Turning over" corpse rearing ground that I met with Master a few years ago. My entire body was covered in goosebumps.

Lao Xu kept flipping through the books as he walked, and he said to me: "I can only tell you that this Feng Shui is called 'Scattering Sand', and I can't explain it to you in two words. You still have a day tomorrow, I'll go take a look first, and tell you the details tomorrow."

"Scattering quicksand?" The name didn't sound that scary, but it shouldn't be something to harm.

As they walked, they discussed with Lao Xu. In a short while, they arrived under "Sunlight Home".

"Sunshine Home" was the name of the district that Sister Kexuan lived in. There were a few buildings there, so it could be considered a medium-sized district.

Lao Xu circled around Sunlight Home's few buildings a few times, and said to me: "Let's go up to the roof to take a look."

Taking the elevator, they arrived at the top very quickly.

The height of the buildings was about the same, I didn't even notice it from a high vantage point, and when I stood at a higher vantage point, I realized that there were six buildings in total. The fifth building looked like a pentagram, while the Sister Kexuan's house was surrounded by the other five buildings, looking like it was filled with stars surrounding the moon.

"All Stars Arching Moon" is also a formation recorded on San Qing Book s, it is also a type of Feng Shui terrain, but I know it definitely isn't like this.

"Although I'm not Feng Shui sir, this kind of building construction, in front, back, left, and right, is completely empty. It doesn't collect money or leave any air, and you still need to build a building in the middle to block the wind. This is simply a big taboo. Who the hell is looking at Feng Shui in such a mess!"

Lao Xu's words confused me. I didn't understand what he was talking about.

He explained to me, "It's reasonable to say that the wind will take away wealth and luck and should be blocked, but this building built according to the situation of the five stars is destined to have no straight line of wind. Once the wind rises, it will gather in the middle of the five buildings and form an invisible cyclone."

It's kind of like the sunken thing from an hourglass of sand. Although there aren't any obvious harmful effects during this period of time, as time passes, it will lead to a weak fire, which is also what we call frail and sickly bodies. If it goes on for many years, it would be the origin of the terminal illness that we usually talk about.

"Anyone who knows a little bit should know that in the middle of these five buildings, there is a flowing water source that can slowly carry away the airflow, or something that can counteract the airflow."

Hearing Lao Xu's words, I started to understand why the feng shui here was called "Scattering Sand".

The airflow gathered but did not disperse. However, it lacked a way to disperse the airflow. If it did not, the airflow would be like quicksand, slowly devouring the person in the middle of the airflow.

I told Lao Xu my thoughts and asked him if that was what I meant.

After Lao Xu heard what I said, he nodded his head and said, "Okay! That's right, it's almost what you mean, you little brat, you have to understand Old Man, that's about it, after all, paper tying is my specialty, and I don't want anyone to understand Feng Shui or anything like that.

I also know what Lao Xu had done for the past month, so I told him: "Aiya, Lao Xu, why are we still talking about what you're doing, after this is over, I'll treat you to a good meal."

"Got it!" Lao Xu seemed to be waiting for me to say that.

"But you have to tell me first, before you can do anything. And why is it that only Zhang Kefan has problems, no one else has any problems."
