"Jun, Kaoru, Hitomi, the three of you entertain Sakura-sa and Harumi, I'll cook."

Aoi Iida walked to the kitchen with the vegetables.

"I'll help you!" As at Inoue's house, Sakurayuki once again offered to help.

"I'll go too." Harumi Inoue echoed.

"No way!" Aoi Iida decisively refused, "You are guests, how can you be allowed to do these things?" ”

"It's okay, what's the matter? It also saves time. Sakura smiled and waved her hand.

"yes, yes, it's okay." Harumi Inoue very much agrees, Sakurayuki didn't win when she went to her house, and now that she is at the Iida house, she doesn't want to show weakness again.

"No, no, no, in short, no!" Aoi Iida is very resolute and unwavering.

After expressing her attitude, she ordered her brother and sister, "Jun, Kaoru, Hitomi, you must watch Sakurayuki and Harumi-sama and don't let them into the kitchen!" ”

"Hey! We're going to defend the hallways to the death. The three of them stood in a row, their hands outstretched in a way-blocking.

"Then I'll leave it to you, come on!" Aoi Iida patted the three of them on the shoulder like a soldier who had just been evacuated from the battlefield and handed over to his comrades on duty, and then walked into the kitchen with peace of mind.

"Come on, we won't back down!" Jun Iida announced loudly.

Sakurayuki and Inoue Harumi looked at each other, and both shook their heads with a wry smile.

Unable to pass, Sakurayuki and Inoue Harumi had to go to the living room and sit on the tatami mats.

Kaoru Iida and Hitomi Iida immediately went to pour tea and get refreshments, and Jun Iida was still standing there as a guard.

"Sister Sakura, Sister Harumi, please use it."

After a while, Kaoru Iida returned to the living room with tea, walked to the small table and knelt down, lifted the teapot and poured tea into the round cup, and served it to Sakurayuki.

"Thank you!" Sakura sat up and took the tea with both hands.

Kaoru Iida then poured another cup and served it to Harumi Inoue.

"Thanks, Hitomi." Harumi Inoue took the tea with both hands.

Kaoru Iida put the teapot in the middle of the small table, and then said with a smile: "Sister Harumi, in fact, I am pure!" ”

At this time, Hitomi Iida came in with refreshments and echoed, "Yes, yes, Hitomi is standing at the door!" ”

"Huh? I'm sorry, I'm sorry, I didn't mean to, pure! Harumi Inoue hurriedly apologized.

"Poof!" The two sisters laughed.

"Huh?" Harumi Inoue didn't understand why they were laughing.

"Sister Yingxue, Sister Harumi, this is the water steamed bun we made, please use it." Hitomi Iida sat down on her knees and placed two plates of small pink, jelly-looking steamed buns in front of Sakurayuki and Harumi Inoue.

"Thank you."

Sakurayuki and Inoue Harumi both bowed down to thank them, picked up one with chopsticks and tasted it, and immediately praised: "It's delicious." ”

Seeing that the two liked it, Kaoru Iida and Hitomi Iida were very happy.

Xie Min observed the surroundings, the interior decoration was similar to Inoue's house, but there were no flower pots or anything like that on the wooden door, and the sliding door was covered with various paper-cut dolls and posters.

"Sister Yingxue, Sister Qingmei, I'm doing my homework, and I don't know how to do a question, can I ask you?"

Although Sakurayuki and Inoue Harumi seem to have given up on going to the kitchen, Kaoru Iida didn't dare to be careless, and after thinking about it secretly, he decided to use the problem Dafa to drag them down.

"Okay."

Sakurayuki and Harumi Inoue both thought that Kaoru Iida was in elementary school, and it would not be too difficult to ask questions about elementary school students, so they agreed without hesitation.

"That's the question."

Kaoru Iida took an exercise book from the side and asked, pointing to a question on the page.

Sakurayuki and Harumi Inoue looked at it together, and the topic was:

"There was a very long-lived old man in a certain village, in his 200s. Everyone in the village knows that the old man lives a long life, but he doesn't know his exact age. A young man came to the old man and asked, 'How old are you?' The old man replied: 'My age is almost 500, and if my age is 13 divisible by 31 and 31 is divisible by 13. How old do you think I am?'

The young man listened and soon learned the age of the old man.

Question: How old is the old man? ”

Harumi Inoue fainted after reading the question, and Sakurayuki was also shocked, this is not an elementary school topic at all.

"Is this really your homework?" Sakura couldn't believe it.

Kaoru Iida nodded: "Yes, I'm going to participate in the math challenge in a while, and this is an extra homework assigned to me by the teacher." ”

"What grade is Jun in now?" Harumi Inoue asked.

"First year of middle school!" Kaoru Iida replied.

"No, it won't!" Harumi Inoue found it unbelievable that Kaoru Iida couldn't look less than ten years old.

Hitomi Iida explains, "Kaoru passed the entrance exam for the middle school of Waseda Industrial School, so she skipped a grade and became a junior high school student. ”

"In this way, I can save a lot of expenses, grow up and go to work early, and earn money to treat my mother!" Kaoru Iida added.

"......" Harumi Inoue wanted to draw a circle in the corner, although Sawaga is also good, but compared with Waseda Industry, there is still a certain gap, and people are skipping grades, and the entrance exam is much stricter than the general admission, and it is more difficult.

Xie Min said secretly: "The sister of a genius girl, this will be a hype point, it seems that Yamamoto Yiyi's means are very good, and even this talent can be discovered." ”

Sakurayuki also admired Kaoru Iida.

"Ahh

Sakurayuki was about to take a closer look at this question when Harumi Inoue suddenly shouted.

"What's wrong? Harumi. ”

Sakura looked at her suspiciously.

Inoue Harumi angrily pointed at Kaoru Iida and said, "It turns out that you are Kaoru, and you lie to people that you are pure, too cunning!" ”

"Hehehehe......" Kaoru Iida and Hitomi Iida both covered their mouths and laughed.

Sakura Xue also smiled, she didn't come in from the beginning, so just now she knew that the two sisters were teasing Qingmei, and she wasn't fooled, she just didn't say anything.

After laughing for a while, Sakura Xue took Kaoru Iida's book and read it a few times, and asked Kaoru Iida to give her a pen and paper, and she wrote on the paper: "Let this person be X years old, x+13=31a, x+5=13b, a and b are positive integers, and the above formula is subtracted, and the collation gets: 31a=13b+8, because every 9 31s are added, divided by 13, the remainder is 8, and it can be seen that a is an integer multiple of 9, let a=9n, n is a positive integer, and 31a=31*9n=279n, n can only be 1, in order to meet the condition."

So x=279-13=266"

"266 years old? How did Sister Sakura's 9 come about! Kaoru Iida asked suspiciously.

“266？” Xie Min was stunned when he heard this, he also read this question when Ying Xue picked up the book, and calculated the result in his heart, which was different from Ying Xue's result.

I checked it again in my mind and realized that I was right, that is, Sakura Xue was wrong.

"That's right...... Sakurayuki began to explain her thoughts.

Xie Min couldn't see that Ying Xue was misleading, so he jumped on the table, crossed an X at 9, and then wrote 12, repeating this. Anyway, they are all children who are still in middle school, so they don't have to be afraid to speak out.

"Meow-chan, are you hungry?"

Kaoru Iida and Hitomi Iida had love in their eyes, and they reached out and touched Xie Min, they actually wanted to play with Xie Min since they saw Xie Min when they entered the door, but in order to drag Sakurayuki and Harumi Inoue, the two of them held back.

Harumi Inoue also thought that Xie Min was hungry and wanted to eat.

"Min is not hungry, but reminds me."

Ying Xue got along with Xie Min for a while, knew Xie Min better, and knew that Xie Min would not make trouble or take the initiative to ask for food, she carefully looked at Xie Min's movements, repeated it, and found that it was an upside-down 12 after writing.

"Reminder?" Harumi, Kaoru, and Hitomi didn't understand what Sakurayuki meant.

Ying Xue already believed that Xie Min was a god, so Xie Min pointed out that she was wrong, she didn't doubt it at all, and after checking it, she found that she was really wrong, the remainder after 9 was brought in was 6, and it was indeed 12! ”

As a result, Ying Xue looked at Xie Min gratefully, hugged him down, and said to Kaoru Iida: "I'm sorry, I'm sorry, I just miscalculated, it should be 12 ...... here"

"No, that's a reminder!" After Ying Xue said 12, the three of them immediately understood that Xie Min wrote 12.

"I'm not as good as a cat!" After understanding, Harumi Inoue was devastated, and her body seemed to turn gray,

"Sister Yingxue, do you still know how to do exercises?" Kaoru Iida and Hitomi Iida asked in shock.

Ying Xue reacted suddenly, this is someone else's house, she immediately glared at Xie Min, and her mind quickly thought about how to be round.

An idea quickly appeared in her mind, Sakura Xue stood up, stretched out two fingers to make a V-shape, compared to the right eye, and made a serious appearance: "Kukukuku, since it has been exposed, then I will no longer hide it, Min and I are actually warriors from the invisible realm, because our hometown was destroyed by a terrible demon, and that demon escaped to this world, so I came to this world to capture the demon......"

"Isn't I the only one who comes from the invisible realm? When did it become me and you. Xie Min glanced at Ying Xue.

Kaoru Iida and Hitomi Iida both listened very carefully, and Junya Iida, who was standing at the door, poked his head out, seeming to be very interested in what Sakurayuki said.

When Ying Xue finished speaking, the three brothers and sisters all adored: "It's amazing!" ”

"Ah, ah, Sister Sakurayuki, can you teach us and make us warriors like you?" Jun Iida asked expectantly.

"No, your spiritual power is too weak, and there is no way for ordinary people to become warriors of the realm!" Sakura said proudly.

"Whew!" All three were disappointed.

"But ......"

"But what?" When the three of them heard that there seemed to be a play, hope suddenly rose again.

"If you stick to exercising, don't be picky eaters, and make your body strong, then there is still hope to become a knight in the realm, and knights are also very powerful......" Sakurayuki began to talk about the benefits of becoming a knight.

The three of them listened with relish, and from time to time they let out cries of worship.

"It seems that no matter how talented he is, a child is still a child!" Seeing that Kaoru Iida was also fooled, Xie Min felt really funny.

"I'm not as good as a cat, I'm not as good as a cat......" Only Harumi was still in gray and white, unaffected by Sakura's words.
