Seeing this math problem again, Manjing suddenly had some more ideas, so she slowly said her idea of solving the problem, but she could only list the known conditions, and then get some other conditions, but how to calculate it later, Manjing didn't know. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Seeing the formulas and proofs written by Manjing, Xu Huaijin couldn't help but nodded, "Actually, you have already written the first step." ”

Manjing was very happy to hear this.

But then he frowned again and said, "But I don't know what to do next." ”

Xu Huaijin's winter vacation homework has been completed, and he has already done this question once, so he talks about it very carefully, and disassembles the solution ideas step by step, so that people can understand it at a glance.

After hearing this, Manjing suddenly realized: "It turns out that the things proved by this condition should be used like this." ”

In fact, Xu Huaijin really talked about the topic very well, Manjing was impressed after listening to it once, and she would be able to meet a similar problem the second time, I believe that the next time she encounters this type of math problem, she will definitely be able to make it.

Cattail had also taken out her winter vacation homework, found out the ones she wouldn't know, looked at Xu Huaijin and asked, "Brother Xu, can you also help me see these questions that I can't do." ”

Xu Huaijin naturally nodded in agreement and helped the cattail look up.

And Manjing found another topic about chemistry, and she carefully read the topic again, and after finding that she really couldn't, she waited for Xu Huaijin to finish talking to Cattail, but she still continued to review the question.

The topic of cattail is relatively simple, so it is very fast, and after a while, Xu Huaijin found that Manjing was doing another course, and found that Manjing stopped writing after a few steps, and he began to talk patiently again.

When Qiao Xianyun came over with food, what he saw was a peaceful picture.

Cattail was doing the question on the side, and Xu Huaijin was explaining the topic to Manjing, Manjing listened carefully, and asked some questions from time to time.

The whole picture is quiet and beautiful.

But Qiao Xianyun felt a little dazzling when he looked at it, although he couldn't tell why, but he just didn't want to see Manjing and Xu Huaijin so close, so familiar and natural to speak.

"Manjing, what are you doing?"

After putting the dishes on the table, Qiao Xianyun walked over with a smile.

Manjing saw Qiao Xianyun coming over, and said with a smile: "Classmate Huai Jin is giving me a lecture. ”

Originally, Manjing had always called Xu Huaijin as a classmate Xu, but once Xu Huaijin proposed it, hoping that Manjing could directly call his name Huaijin, saying that it was too rusty to call classmate Xu.

Manjing felt that it was a bit strange to call Huai Jin directly, so in the end she became Huai Jin's classmate.

"Oh, will it be now?" Hearing this, Qiao Xianyun walked over and took a look.

Manjing smiled and said, "I will now." ”

"Classmate Huaijin, since Manjing already knows, then you and I will go to the kitchen to serve the food, we have already prepared the meal, as long as it is served, we can eat it." Qiao Xianyun raised his eyes and glanced at Xu Huaijin, and said with a smile.

Xu Huaijin nodded when he heard this, and followed Qiao Xianyun to the kitchen.

Cranberry and Cattail put away all the textbooks and test papers, began to put the stools away, and went to the kitchen together to get dishes and chopsticks.

When the last bowl of soup was served, all five of them were seated.

It was rare for Manjing's birthday, Old Man Luo took out a bottle of wine and poured some for himself, while Qiao Xianyun and Manjing poured some juice, and the five of them held the bowl and toasted.

This juice was made by crushing the peaches in the space.

At the beginning, Old Man Luo was distressed when he saw Manjing holding a good peach to make some juice.

But since he drank the peach juice pressed by the cranberry, he didn't speak again, this peach juice is really delicious, but he still has some doubts, and he doesn't know where to buy such a good peach from the cranberry, why hasn't he always seen the peach seller that Cranberry said.

These thoughts only appeared in Old Man Luo's mind for a moment, and then he didn't think much about it, anyway, Manjing was lucky, and he could buy cheap and delicious peaches every time.

"Manjing, speaking of a bowl of longevity noodles, you must eat a bowl for your birthday today." As he spoke, Old Man Luo gave Manjing a small bowl of longevity noodles from a big bowl, and then also a small bowl of cattails, and then said to the other two: "Little Qiao Huaijin, you must not be polite, you can eat whatever you want." ”

Qiao Xianyun and Xu Huaijin both nodded when they heard this.

After a few people finished eating, Old Man Luo pulled a few people to start drinking tea and chatting, digesting and digesting by the way.

After chatting for a long time, Qiao Xianyun stood up and said, "Old Luo, I'll go home first." ”

Manjing hurriedly raised her head to look at Qiao Xianyun, and couldn't help asking, "Brother Xianyun, are you...... Going back? ”

Seeing Manjing's nervous appearance, Qiao Xianyun's mood suddenly improved, and he said with a smile: "I'll go home first." After that, he didn't say anything, but he looked at Xu Huaijin and said, "Isn't Huaijin going back?" ”

Xu Huaijin was stunned when he heard this, he didn't understand why Qiao Xianyun wanted to leave by himself, why did he still ask him if he wanted to go, he instinctively wanted to shake his head.

However, Qiao Xianyun immediately continued: "Cranberry and Cattail have the habit of taking a nap, so if we stay longer, we will disturb them." ”

Although Cranberry and Cattail did have the habit of taking a nap before, but now in winter, they don't sleep at noon, and Cranjing just wanted to say something, when she saw Qiao Xianyun winking at her.

Although she still didn't understand why Qiao Xianyun said this, Manjing still instinctively stopped her mouth and didn't say what she originally wanted to say.

When Xu Huaijin heard Qiao Xianyun's words, he could only stand up and say goodbye to Old Man Luo and the others.

Looking at Qiao Xianyun and Xu Huaijin who were leaving, Manjing said with some doubts: "Why did Brother Xianyun suddenly go home, didn't he say yesterday that he would stay here for the next few days, not to mention that he hadn't cleaned up at home, and he couldn't live there." ”

Old man Luo frowned, he always felt that Qiao Xianyun was a little strange today, especially when he was about to leave, he called Xu Huaijin to leave together, and said that the two Manjing sisters want to take a nap, what kind of nap in this winter.

But after thinking about it, he didn't understand Qiao Xianyun's actions, so he didn't think about it anymore.

In Old Man Luo's heart, he has always regarded Xue Hai and Qiao Xianyun as the same generation, so he doesn't think about some aspects at all, so although he thinks that today's Xiao Qiao is a little strange, it is just a feeling.

Naturally, Cranberry and Cattail didn't take a nap, and the two of them read the book directly.

But after a while, there was a knock on the door outside the courtyard gate, and Manjing hurriedly stood up to open the door, and when she saw Qiao Xianyun outside the door, she smiled crookedly.
