Also, many thanks to everyone who bought me coffee (*≧?≦*)
The girl in purple still couldn’t stop thinking about the new Zhuangyuan even to this day. Incidentally, she would also think of this woman who was treated differently by the new Zhuangyuan.
Obviously she wasn’t good-looking, but after the flower hairpin event, her appearance and manner of dressing became popular in the capital. Even the girl in purple herself had someone paint a small begonia flower on her face.
The young Taoist nun looked at Gu Jiao and murmured, "Yes ah. What a fate indeed."
Gu Jiao helped the old man up and purchased a catty of tea leaves from him. The surrounding people probably felt that their behavior of just standing by and doing nothing wasn’t as good as that of a girl in her teens. Feeling ashamed, they also bought tea leaves from the old man.
The baskets of tea leaves were sold out.
"Thank you, young miss, thank you!" The old man cupped his hands and thanked Gu Jiao with emotions.
Gu Jiao turned around and got back into the carriage. contemporary romance
It wasn’t until the carriage disappeared at the end of the street that the young Taoist nun slowly retracted her gaze.
Gu Jiao gave the tea leaves she bought to Little San and then went back to Bishui Alley.
Gu Yan and Gu Xiaoshun were not back yet. Little Jing Kong went to Granduncle’s side while Grannie Fang was cooking in the kitchen.
Xiao Liulang plunged headlong into the study. Even when Gu Jiao pushed the door open, he failed to notice it.
He was seldom so lost in thought. Gu Jiao walked over and found him drawing an image.
"What is this?" Gu Jiao asked.
The lighting in the room was a little dim, so she had to come closer to see the drawing.
When Xiao Liulang heard her voice, her head was close at hand, and her warm breath intertwined with his own breath.
Xiao Liulang's heart skipped a beat, his eyelashes trembling slightly. He thought he should move away, but his body remained motionless.
"Arithmetic." Xiao Liulang answered, "I'm cutting a circle."
"Cutting a circle? Are you trying to calculate the Zu rate?" Gu Jiao was actually not sure whether this time and space also called pi Zu rate.
"You know about the Zu rate?" Xiao Liulang was surprised. Even though he knew there were many secrets surrounding her, he didn't expect it to be so many. She even knew about the Zu rate.
When she heard him ask about the Zu rate, Gu Jiao understood that this time and space also had some overlapping parts with the time and space of her previous world, such as pi. Originally, Liu Hui calculated the pi up to four decimal places, which was called Hui rate, and then Lord Zu calculated it up to seven decimal places, which was called Zu rate.
Among them, Liu Hui used the circle cutting method during the Wei and Jin Dynasties. As for the Zhui method of Lord Zu during the Northern and Southern dynasties, it seemed to have been lost to time no matter which time and space it was, otherwise Xiao Liulang would have used the Zhui method right now.
The circle cutting method was to use the area of a regular polygon inside a circle to infinitely approximate the area of a circle and to calculate the value of pi.
Starting from drawing a hexagon inside the circle, Liu Hui cut it up to 3072 sides, so that it was finally accurate to the four fractional digits between 1415 and 1416.
This amount of calculation was huge and overwhelming. If he had used calculus instead, it would be much faster.
Gu Jiao said without changing expressions, "I heard it from the students of the women's academy."
The women's academy also had arithmetic classes, but Xiao Liulang wasn’t clear about its specific contents.
However, he knew that Gu Jiao was extremely smart, and that she could never forget what she had heard once.
Gu Jiao added, "Why did you suddenly think of doing this? Is it homework from Hanlin Academy? "
"No." Xiao Liulang shook his head. After some hesitation, he still told her about what happened between Little Jing Kong and Teacher Sun, mainly because he wanted to find out whether Little Jing Kong's knowledge of Zu rate and those arithmetic problems were taught to him by Gu Jiao.
As for Teacher Sun's angry crying as well as the bet between them, he didn’t mention them, only saying that he already had a harmonious discussion with the other party.
Gu Jiao went ‘oh’, and shook her head.
She did teach Little Jing Kong some arithmetic, but she didn't teach those questions to him nor she taught him the Zu rate.
"He could recite such a long value of Zu rate?" Gu Jiao was stunned.
Xiao Liulang called Little Jing Kong in.
When Little Jing Kong saw Gu Jiao, he almost thought that his bad brother-in-law secretly told on him. However, seeing Gu Jiao's usual expression, he was relieved.
Xiao Liulang said, "Recite the Zu rate you recited in front of Teacher Sun again."
Little Jing Kong recited it obediently.
Xiao Liulang: "I don't know if it's right, so I have to do the math."
People would never believe that Little Jing Kong was correct, because there were only seven fractional digits recorded in the book, but he recited seventeen.
Xiao Liulang did not immediately dismiss Little Jing Kong.
It wasn’t that he believed Little Jing Kong was right, but that he couldn’t prove Little Jing Kong wrong.
He wouldn’t suppress people just because he was older and had studied for more than ten years.
A reprimand might deter a child, but it wasn’t because the child was convinced, but because the child had given up the desire for knowledge.
Gu Jiao knew that the value of pi Little Jing Kong just recited was completely correct.
"Who taught you that?" Gu Jiao asked.
"I read it in a book." Little Jing Kong answered.
"What book? Can you show it to us?" Gu Jiao asked again.
"Of course!" Little Jing Kong ran out, rummaged through his pile of junk, and found a yellowed book with curled corners.
He handed the book to Gu Jiao, "JiaoJiao, here!"
Gu Jiao took the book and looked through it together with Xiao Liulang.
With just one look, the two people were uniformly shocked.
Gu Jiao was shocked because she saw familiar words and formulas, while Xiao Liulang was shocked because he saw patterns and words that he didn't understand at all. At the same time, under these strange words and patterns, there were annotations in another language.
It was the language of the State of Yan.
It was no wonder that Little Jing Kong could understand some of it as he had been learning the State of Yan’s language recently.
However, wasn’t it strange that he had the State of Yan's book?
Moreover——
Xiao Liulang turned to the last page and gasped when he saw a big seal on it!
This couldn’t be the national book of the State of Yan, right?
The State of Yan was the most powerful state among the six countries, but who would have thought that it was just a small country a few decades ago?
Suddenly, one day, a powerful State Preceptor came to the State of Yan, and he brought with him six great ancient books. It was the secrets within these ancient books that made the State of Yan rose like a bamboo shoot after a spring rain.
The treatment of leprosy was also recorded in these ancient books.
In the end, these six ancient books were sealed as national books and kept in the imperial palace of the State of Yan, guarded by hundreds of imperial experts day and night.
If this national book was real, was the one in the State of Yan’s imperial palace fake then?
That… That shouldn’t be possible, right? After all, Jing Kong was just a little monk who would faint when eating meat.
Gu Jiao didn’t know about national books or whatnot, but she could conclude that the simplified characters and advanced mathematical formulas in this book didn’t belong to this time and space.
Could it be, she had a senior transmigrator here?
