Gao is not fat, he goes fast, and he comes quickly, just two days of kung fu, he returned to Xiang'an, and the news he brought back made Yu Guozhen feel more confident.

Qingming passed in a blink of an eye, after Qingming, Yu Guozhen's filial piety period was officially over, but his life did not change, he still ran every day, taught the two pillars to read and count, and rarely went to the town. And the last time, in addition to tossing in the fourth room for a few days, it was also like a stone falling into the water, although it splashed, but it quickly regained calm.

On April 10 of the fifth year of Chongzhen of the Ming Dynasty, the originally clear sky began to change suddenly in the afternoon, and the wind and waves on the surface of the West River were fierce, and the ships had to anchor at anchor to temporarily shelter from the wind and waves.

"Miss, this wind and rain are too big, if you are not careful, the boat may capsize, there is a family on the shore, do you want to avoid it?" The rain was so heavy that a woman sticking her head out of the curtain on one of the boats asked into the cabin.

"Look at the family and see if there are any female dependents." There was a thin voice from the cabin, and it was so crisp that it sounded like the "young lady" was not very old.

The woman waved her hand to the boatman: "Old horse, go up and have a look, if there are any female dependents, ask if it is convenient for us to shelter from the wind and waves!" ”

The boatman, barefoot, jumped directly to the shore, and he rushed into the rain, and after a while he rushed back: "The master of this house has set aside the main house, and there is a servant maid ring in the house, and the young lady can go ashore to take shelter - this wind is really strong!" ”

After a while, a boy of half the age rushed over, bringing five coats and three oil-paper umbrellas, but in such a strong wind, the oil-paper umbrellas were difficult to hold.

It was Gao Erzhu who came, although he was tall, but he looked childish. The boatman set up the gangway, but the ship fluctuated in the strong wind, and the gangway was unstable. Seeing this, Erzhu jumped into the water and pressed the gunwales firmly, and the boatman hurriedly thanked him, and then Erzhu saw a little girl like white jade walking out of the cabin.

"It's raining so hard, sister!" The little girl turned back to the cabin and shouted, "Come on, come and see." ”

She was only seven or eight years old, she looked like a pink carving, and in the midst of laughter, a pair of eyes were bent into crescent moons, and the wind and rain outside did not make her feel afraid, but made her feel excited.

She shouted and staggered onto the gangway, so frightened that the servants who had just come out of the boat had straight eyes, and hurriedly came up to help her ashore, and finally did not fall into the West River.

This West River leads to the Yangtze River, and at this time, the wind and waves are strong, and if you are not careful, you will lose your bones. The servant woman turned around, and helped out of the cabin a young girl, who was thirteen or fourteen years old, and looked very much like the little girl who had just come out, but was much quieter and more dignified. She cautiously went ashore and thanked Gao Erzhu, who smiled and said, "My master ordered it." ”

"What is your master's surname?" Hearing that the half-boy was honest, the servant woman asked.

"Yu, my master said that he is a descendant of Yu Shu when he was the Yellow Emperor, and he has nothing to do with the Yu family of the second prince and the second marquis."

The servant woman couldn't understand why he emphasized that he had nothing to do with the Yu family of the second duke and the second marquis, you must know that around Chaohu Lake, the Yu family of Emperor Taizu, one father, three sons, two dukes and two marquis who saved the country at the beginning of this dynasty is the most famous! However, the thirteen or fourteen-year-old girl's eyes were slightly fixed and thoughtful.

"Sister, come on, there are flowers everywhere here!"

The little girl who got off the boat first had been detained in the yard for a long time, so everything was new, and the mud and heavy rain couldn't stop her good mood, so she jumped up and down to Yu Guozhen's house, and stopped from time to time to call her sister. The thirteen or fourteen-year-old girl had to roll up her sleeves and follow quickly.

When the sisters ran under the eaves, Yu Guozhen happened to come out, and the little girl almost hit him. Seeing this little girl carved like pink, Yu Guozhen felt that his mood suddenly became happy, and then he saw the girl following the little girl.

This girl is only thirteen or fourteen years old, her body has not yet grown, she is covered under a wide robe, and she can't see anything, but with a jade-like face, a pair of star-like eyes, a straight nose, and a little cherry mouth, Yu Guozhen was stunned when he saw it, and felt as if he saw the person in the picture walking out.

Seeing him, the girl immediately put down her skirt, but at this glance, Yu Guozhen realized that she didn't wrap her little feet.

It was late Ming, the wind of foot-binding was in full swing, and there were really not many ladies in the Jianghuai area who did not bind their feet. The girl's cheeks were red, and her face was embarrassed, although she had fallen into her family and joined her relatives, she was also the daughter of a famous family, and it was really inappropriate to be looked at her feet like this.

"Xiaolian, lead these two young ladies in." Yu Guozhen instructed backwards: "Aunt Gao, burn a pot of charcoal and let the guests warm up." ”

He commanded in his mouth, but his heart jumped wildly, and his eyes couldn't help but be a little confused. Fortunately, the girl happened to hear his command and knew that he was the master, and blessed him, but did not see it, otherwise she would have regarded him as a disciple and would not dare to enter the house at all.

Although he was only fifteen years old, he was already able to appreciate the beauty of the girl, although this girl was not a stunning beauty, but for some reason, he just felt pleasing to the eye.

Fortunately, the atmosphere in Jianghuai is more open than elsewhere, otherwise it would be impossible for this girl to enter Yu Guozhen's house.

The maiden was followed by three servants, one of whom was a rough maid, and four other boatmen. The girl and the sisters were introduced into the main house, and Aunt Gao immediately brought a charcoal fire, and they looked around, although the house was simple, but there was nothing to say about the cleanliness, unlike ordinary villagers, chickens and ducks would feces in front of the hall. The little girl, whose surname was lively, did not go to the fire after untying her coat, but walked around the hall and saw a stack of papers on the table. She flipped through it curiously, and then ran over to her sister as if she had made a big discovery: "Sister, sister, what do you think this word is?" ”

"Hugh wants to touch other people's things!" The girl's face sank.

The little girl was not too afraid, she just stuck out her tongue, glanced at the paper again, and finally couldn't hold back her curiosity: "Sister, they put it here, they must not be afraid of people looking at it, you see, what is written here, why can't I recognize a few words?" ”

Although the girl taught her sister a lesson, she was thirteen or fourteen years old after all, and if she was placed in the next generation, she could also take the last train of the word "Lori", where would there be no curiosity, and she couldn't help but glance at it. At this glance, her eyes lit up: "Hey, this is...... Xiyi Numbers! ”

She saw the fine handwriting on the paper, which was Arabic numerals. At this time, it was the first time that Western learning was moving eastward, and among the people of insight and advanced scholars in the Ming Dynasty, quite a few people took the initiative to consciously learn these science and technology from the West, instead of being beaten to the point that they didn't even have any pants left like the puppet Qing Dynasty in later generations. Although her family is a generation of Confucianism, her cousin has learned some Western studies from Xiong Mingyu in Fujian, so he knows these numbers. And she has always admired her cousin, and often asks him for advice, so she can barely recognize some of them.

It's just that in this remote wilderness, there are people who know Xiyi numbers, which really surprised her.

"This is our family's petty officials who teach the big pillars and the second pillar to count." Xiaolian next to her was only a year younger than her, and when she was so surprised, she naturally said proudly: "My little master knows the most things, whether it is Xiyi or Dongyi, as well as Beiyu and Nanban, there is nothing in the world that my little master does not understand!" ”

The little master should be the fifteen or sixteen-year-old boy I saw just now, the girl heard her worship like this, and felt interesting in her heart, of course, she was a little unconvinced, you know, in her heart, her famous cousin can't afford to be praised for knowing everything in the world, let alone this country boy?

But she didn't like to win because she was surnamed, she just hid this fun in her heart and didn't say it. It's her sister, the **-year-old girl doesn't know how to hide what she thinks, so she pouted and said: "I don't believe it, it's impossible, your little master definitely doesn't know as much as my cousin!" ”

Xiaolian's mouth squirmed, but she remembered that the other party was a guest, so she didn't say anything. The little girl knew that she was not convinced, her eyes rolled around, and she thought of some interesting things that her cousin had said: "Does your little master know whether the land is square or ...... Flat? ”

The so-called round sky, when people think that the earth is square, so the little girl asked. Xiaolian twitched the corners of her mouth slightly when she heard this: "It's not square or flat, it's round, my little master not only knows that the earth is round, but also knows that the diameter of the earth is about 25,400 miles...... Three years ago, my little master said this! ”

As soon as these words came out, the little girl searched her stomach to find a new question, but the girl next to her widened her eyes. If you know those Xiyi numbers, you can still say that they are taught by Xiyi, and knowing that the earth is a ball is only average, and it is possible to accurately calculate the diameter of the earth, which is definitely not possible for ordinary people!

Could it be that this little girl is talking nonsense, or is it made up by the little master at will?

Thinking of this, the girl couldn't help but want to verify it, so she turned her eyes and remembered a question she had seen in her cousin's new manuscript, so she asked, "Since you know that the earth is a ball, do you know the equator?" ”

"The circumference equal to the north and south poles is the equator...... However, the little master said that it should be the longest weekly line when the earth rotates! ”

This made the girl's mind a little confused, but what she wanted to ask was not this, as long as she knew the equator, it would be easy to do: "So how many degrees does China live in the south of the equator or the north of the equator?" ”

Xiaolian was stunned for a moment, she thought for a while: "The little master said that I live in the north of the equator in China, as for how many degrees...... After I have asked the little master, I will return to the two young ladies. ”

After she finished speaking, she walked out quickly, and the little girl laughed loudly: "My sister is still smart, so I can't stump her!" ”

The girl frowned slightly, this question, can it really stump the little master?
