Very elegant yard, the first impression is clean.

There is not a trace of dust on the stone pavement, and the bluestone is as clean as if it has been washed.

Xie Caiwei came to the front of the small building, pushed open the door and said, "Wait a while." ”

Yuan Lai obediently stopped outside the building, and the water all the way was dripping all the way, and there were no droplets of water falling at this time, but it was very uncomfortable.

He looked around, and there were flowers and plants in the yard, and there was a small pond with fish in the pond, and a yellow cat by the pond was lazily examining him.

It's quiet, it's good for reading, it's good for learning.

"This is my brother's clothes, you can change them. Xie Caiwei came out with a Confucian dress and said slowly.

"Where do I change it?"

"That's it. Xie Caiwei stretched out her hand and drew a circle in the courtyard.

"Right here?" Yuan Lai was a little desperate.

Xie Caiwei looked around, thought for a while, and explained: "There are many books in the building that can't get wet, so let's do it here, don't worry, I won't peek." ”

“......”

When the door of the small building was closed tightly, Yuan Lai was a little at a loss with his clothes, he looked at the gate of the courtyard, and changed his clothes directly, but the clothes were soaked from the inside out, so ...... Not good...... After all, it's in someone's girl's house.

The cool breeze blew, he couldn't help but sneeze, the water of the Qinhuai River was cold, he already knew it deeply, although the weather was not cold, but he had no doubt that he would be infected with the wind chill after being soaked for too long.

Yuan Lai gritted his teeth and ran to the edge of the pond so fast that the cat jumped up.

......

After changing the clothes, Yuan Lai breathed a sigh of relief, this dress is a little big, but fortunately, the robe that was originally a Confucian was not ugly if it was wider.

He knocked on the door and said, "If it's changed, then I'll ......."

Xie Caiwei didn't look at him, but just said, "Come in and do me a favor." ”

The most things in the small building are books, he didn't come in before he didn't notice that something was wrong, and when he entered the building, he suddenly found that the first floor of the small building was very wide and huge, and the shed was very high, and the first and second floors of the small building were opened.

There are huge bookshelves on three sides of the building, and there are thousands of books and paper rolls that are densely packed with books.

In addition to paper books, there are also bamboo slips, silk books, wooden board books, etc., which are very spectacular.

In addition to the most books in the whole room, there are calligraphy and paintings, all the blank walls have landscapes, and the largest of them has only a huge and mellow "Zen" character on it, Yuan Laizheng was surprised to see Xie Caiwei holding a few large painting scrolls, and slowly stuffed them into a vase of half a person high in the corner of the wall.

"How can you help?" asked Yuan Lai.

Xie Caiwei didn't answer, but leaned sideways and began to look at him, Yuan Lai's image was not bad, and it could be seen that she seemed to be very satisfied.

"I know you. Unexpectedly, Xie Caiwei said.

"You're talking about Xilinbi?"

Xie Caiwei shook her head and said, "No, it's a few days ahead of that." ”

Her hands habitually shrunk into the sleeves of her Confucian robe, and her voice was soft, like the sound of reading.

Yuan Lai was a little strange, and after thinking about it, he suddenly remembered Shencheng's Shouyang Tower, so he asked, "When was that?"

Xie Caiwei came to the desk by the window, flipped out a stack of papers, pulled out another one from it, and began to read the words on it: "The sassy west wind is full of courtyards, and it is difficult for the cold fragrance and cold butterflies to come." If I am the Green Emperor in his year...... The newspaper and the peach blossoms bloom together...... That's what you wrote, right?"

Yuan Lai could only nod and said with a wry smile: "Is it a matter of Shen Cheng? I didn't expect it to be transmitted to the capital." ”

Xie Caiwei said leisurely: "My brothers went to the north and south of the river, Shencheng was the place where the first failure, this is not a very small thing in Wuyi Lane, this poem was brought back by my brother, and he also told me that he felt very unconvinced." ”

Yuan Laiqi said: "I remember that Shencheng is the seventh city you are parade, and I haven't been in the capital for long, have they all finished their parade and run back?"

"Not yet, but my brother came back on his own. ”

"Why?"

"My brother said that since he lost once, he didn't want to continue to go to other cities, and he couldn't afford to lose that person......"

"......" Yuan Lai was speechless, and said in his heart that this is the temper of a proud reader.

"So I said, I know you, it's been a long time. Xie Caiwei smiled.

"No wonder you dared to bring me home. Yuan Lai sighed.

Xie Caiwei smiled: "I'm just a little curious, so I should satisfy my curiosity." ”

"Are you satisfied now?"

"It's still a little worse," Xie Caiwei thought for a while and said, "That Xijiangyue's arithmetic problem...... How do you do that?"

Yuan looked at this girl who was exuding the fragrance of books from every strand of hair, and felt inexplicably a little close, he walked to the desk, took out a blank piece of paper, took a fine brush from the pen holder, drew a figure on the paper, and said: "That's it, I call this solution the 'Pythagorean theorem'." ”

"Hook three, strand four, string five?"

"That's it, you see, that's it. ”

Xie Caiwei's eyes were shining and staring at the theorem on the paper in a daze, Yuan came to see it in his eyes and couldn't help but sigh at the low progress of mathematics in this world, the girl looked at it for a while and asked, "This Pythagorean is recorded in that book?"

Yuan Lai still remembered this question, but he was a little hesitant to know whether there was a "Zhou Ji Sutra" in this world, but when he came into contact with the girl's bright eyes, he felt that whether there was a book or not was no longer an important question.

""Zhou Ji Sutra"?" Xie Caiwei frowned, thought for a while, and suddenly said with a flickering gaze: "I remember that I seem to have seen this book, but I haven't read it, and that book should be placed in ......."

"Can you help me move the ladder?"

......

The bookshelf where the "Zhou Ji Sutra" is placed is very high, it is actually on the top floor of the entire bookshelf, such a height must be with the help of a ladder, Yuan Lai carried the ladder and put it away, Xie Caiwei carried the robe and began to climb, leaving Yuan Lai to support it underneath.

Seeing that the girl was climbing higher and higher, Yuan Lai suddenly understood why she had to question her question in the highest position of Xilin Wall, looking at the proficiency of her movements, it was obvious that this was commonplace.

The girl was carefully counting the names, and there were many books on the top floor, and she could only read them one by one, which was very laborious and tiring.

Yuan Lai looked up, he should have seen a beautiful scenery from this angle, but the hateful thing was that the scholar's robe was too big, blocking a lot of vision, and of course, more importantly, the fifteen-year-old girl had not yet developed.

He sighed and said, "You have so many books here, how laborious it is to find them, haven't you made an index?"

"Index?" Xie Caiwei on the top of the ladder shook her head and said, "I don't need it, because I can remember it!"

Saying that, she was a little surprised and said, "Found it!"

"Zhou Ji Sutra" is really inconspicuously hidden in the middle of several arithmetic notes.

Yuan Lai also happily watched Xie Caiwei reach out and pull it out of the bookshelf, but maybe the position of the book was too tricky, or maybe the girl was careless, in short, Yuan Lai, who was doing nothing, suddenly felt the ladder shake, and then there was an exclamation!

The girl actually fell down the ladder with the book in her arms!

Yuan didn't have time to think about it and hugged Xie Caiwei, but after all, this thing was too sudden, and the skills of catching a person were not skilled, so he also shook his body, and could only try his best to put his back on the ground, and Peng Peng hugged the girl and fell to the floor.

"Ahh

"Hey!"

In a hurry, the two rolled down together, and their postures were a little indecent, a little embarrassing, and a little ambiguous.

At this time, the door of the small building was pushed open.

"Little sister, my father is looking for you for something......

Xie Eighteen said as he pushed the door, and then he was only halfway through his words, and his face stiffened, because he saw a very indecent scene in the room.

He was stunned for a moment, and then shouted, "You, let go of my sister!"
