Ma Yuan is in his thirties, and he still has a wife, and there are only two concubines who can't go to the hall, and they gave birth to a girl and a boy respectively.

The five-year-old boy Ma Liao is his eldest son, and he was brought here by his sister today to avoid suspicion.

Because women can't easily report their names to strangers these days, let's call her "a certain unnamed lady Ma".

Maoling Ma's family education is very good, even if Ma Yuan has not been at home for more than ten years, even if she is only the eldest daughter, she also follows etiquette: sit upright with the instep of the ground, put your hands on your knees, lean slightly, only look at the knees of the fifth Lun to talk, and avoid looking at him.

This is called "sitting together", and it is the sitting posture when facing His Holiness and elders.

After all, according to the brains of the people of Chang'an, Wu Lun, Ma Yuan, and Wan Yu are only close to becoming brothers like Liu Bang and Xiang Yu. Lady Ma probably heard a similar story and automatically assumed the role of the eldest niece, even though she was only three years younger than Fifth Lun.

"With the help of two uncles, the Wuwei Siming Mansion did not embarrass my family, but I heard that the fifth Lang official was also imprisoned by his father."

Lady Ma apologized to Wu Lun on behalf of her father, but she obviously didn't come for this matter, so she couldn't help but say: "Dare to ask Wu Lang Guan, why did my father set up a prison that day?" ”

Of course, it's because Ma Yuan and Wan Yu are in love.

The fifth Lun briefly explained the process, and there was no lack of praise for Ma Yuan's righteousness in his words, and the Ma lady listened silently, with a somewhat complicated expression on her face.

One will be the pride and pride of his father's righteousness and daring, and the other will be the resentment that he is a stranger and abandons his family.

At the end she asked, "Has my father ever left a message about where he is going?" ”

Everyone came to the door to ask "where is Dad", but the children couldn't report Ma Yuan, so Wu Lun said: "Wen Yuan said before leaving, he will go to Yidi County (Beidi County) with Wan Xuan to wait for amnesty." ”

The northern land is the area of Ningxia, Gansu in later generations, close to the Xiongnu, which is a weak area of the imperial court and a perfect place outside the law.

Ma's lady glanced at her younger brother and said with a wry smile: "The fifth Lang official really knows, but we don't know...... The county is very large, but which county can you go to? ”

Although the Ma family is big, but Ma Yuan's family is only supported by her eldest daughter, it is really not easy, and the fifth Lun can only forcibly round it for Ma Yuan: "Or if you haven't settled down yet, you will definitely reply to the letter after a while." ”

The lady of the Ma family sighed secretly, and only said: "If my father comes to the news, I hope that the fifth lang official can inform Concubine Yu." ”

After that, he took his younger brother by the hand, saluted together, and then said goodbye. The posture is also exquisite, Yingying tends to be in the house, and after getting into the car, she bowed her head to the fifth Lun and left Xuanmingli.

Wu Lun was sent out of the house, but he stood in place and watched for a long time, and after the car shadow disappeared, he only sighed: "Ma Wenyuan and I are also friends in trouble, like brothers, he died in the rivers and lakes, and I should help take care of one or two of his children, five blessings."

"No."

"Wait a few days to return to the fifth mile, remember to ask your father to prepare the best manor products and send them to the Maoling Ma Clan's mansion."

At this time, they heard the twilight drum roaring.

There were a total of 600 closed-door drums in Chang'an City, and after they were beaten, the whole city was curfew. Calculating the time, the two sisters and brothers of the Ma family should be able to rush back to the lieutenant's mansion in time.

Fifth Lun frowned and looked up at the still bright sky: "Could it be my delusion?" Or the ice and snow reflect the sky brighter, and today's twilight drum seems to be much earlier than usual! ”

……

Knock knock, when the twilight drum sounded, Liu Xin in the National Teacher's Mansion had just put down his calculations.

Faced with the string of mysterious numbers left by Wu Lun, Liu Xin initially scoffed: "I know Yang Ziyun, he is good at dictionaries. Huan Junshan commented that he was 'profound in literature and meaning, and he was not a saint', but in terms of mathematics, Yangxiong had no achievements. ”

Liu Xin, on the other hand, is a generalist, who talks about the biography of the six arts, and investigates everything, including Zhuzi, poetry, mathematics, and square skills.

Therefore, most of this number is made up by the fifth lun.

However, when Liu Xin casually put it into his own puzzle that was stuck due to the lack of accuracy of pi, it was strangely solved.

Liu Xin was quite surprised, it was impossible for Fifth Lun to guess by chance, right?

Liu Xin has an obsession with academics, and when he was young, he repeatedly asked his father Liu Xiang about difficulties. When people spoke lightly, they brazenly moved the book to blame Dr. Taichang, and the famous Confucian doctors Gong Sheng and Shi Dan were all sprayed by Liu Xin. If you really want to talk about the Five Classics and you can't talk about this, the Confucians can only use their power to suppress Liu Xin politically and suppress the ancient scriptures.

Many years later, Liu Xin returned to the court with the support of Wang Mang, and became a scholar who said the same, and no one dared to oppose him anymore.

Now that he is inferior to a son in pi, Liu Xin is quite unwilling.

Liu Xin relied on circumcision to calculate pi, which originated from seeing stonemasons processing stones when he was young. Originally, a square stone, after the craftsmen chiseled off the four corners, became an octagonal shape. Go to the octagonal again, and it becomes a hexagonal again.

Axe after axe chiseled down, and the square became a circle.

"This is what Sima Qian said: Break the eyes and become a circle!"

Therefore, Liu Xin adopted this method, using a circle to cut polygons to approximate a pure circle—but it was different from later generations cutting from the inside of the circle.

Theoretically, the finer the cut, the more calculations, the smaller the error, and the exact pi can be obtained.

Now that he was slapped in the face by the number of the fifth lun, Liu Xin wanted to prove it, so he had to cut it again on the basis of cutting it so that it was uncutable.

There are more and more edges outside the circle, and the calculation is becoming more and more complicated and difficult.

Liu Xin remembered that the old enemy Yang Xiong once described the difficulty of making a fu, saying that when he wrote "Ganquan Fu", he thought about it hard, meditated day and night, and was so tired that he was overwhelmed.

In a trance-like sleep, Yang Xiong found that all his internal organs were flowing out. He hurriedly picked them up with his hands and carefully put them back. When he woke up from the nightmare, he found that he was really injured, as if he had been seriously ill for a year.

And Liu Xin is not much better, he thinks hard, he thinks about eating and sleeping, and the first thing he does when he wakes up is to pick up the calculation. The location has also shifted from the outdoors to the indoors, no one is allowed to set foot in the room, and the precise calculations do not allow any disturbance.

To this day, after exhausting his mental strength, Liu Xin found that he still couldn't do it accurately, but the more he calculated, the more the new number obtained was closer to the fifth Lun's "3.1415926".

In a few more years, it may be possible to cut to a few thousand sides.

But Liu Xin is exhausted, tomorrow is the sixth year of Tianfeng, as a national teacher, he has to dress in court clothes and enter the Shoucheng room to meet the emperor.

After Liu Xin wrote down the results on the slip, he went out to rest under the peach tree, still thinking in his heart: "How can the fifth Lun be calculated?" Could it be with the help of the power of the gods? ”

When he was awakened, he also heard the sound of the twilight drum, opened his eyes and looked at the sky, Liu Xin didn't need to miss a moment to know that today's closed-door drum was two minutes earlier than usual!

"Uncle, Wuwei Si ordered Chen Chong to bring troops to Shangguanli!"

Nephew Liu Gong hurriedly came to report, he was full of surprise at what happened outside, but Liu Xin seemed to know about it, and he didn't panic at all.

"It looks like it's today."

"Your Majesty, I don't plan to keep Wang Zong for the New Year!"

……

This is the fifth day of the Eighth Correction's appointment as "Gong Chong Gong Xian Ma".

Xian Ma's main job was to serve as a guide when the prince traveled, but in the palace, Wang Zong heard that the Eighth Jiao family had passed on Korean poems and learned Shangshu, so he asked him to read them.

The eighth correction was able to get close to Wang Zong and found that Gong Chonggong's hobby was very special: he liked to paint and carve seals.

One day I read "Shangshu. In the Book of Zhou", Wang Zong sighed and confided his heart to the eighth correction.

"This is the origin of my title, the ancient saint, the reason why he can achieve great deeds is because he has great ambitions. As the grandson of the emperor, I also have the world's society in my heart, and I only hope to become a gentleman like the prince of Wei, so that the people of the world can fight for it, and there will be 3,000 diners, so as to assist the Son of Heaven and make the new room long and stable. ”

The eighth correction was touched by Wang Zong's ambition, and when Wang Zong asked him "what are the virtuous people in Taixue", the eighth correction also knew everything.

He also promised to wait for the beginning of spring to recruit Liu Xiu, Liu Long and other generations for Wang Zong to come to see him, and help Gong Chonggong defend the new mountains and rivers together.

To this day, the dream that has just been built in the past few days has been shattered.

Because it was the last day of the new calendar, Gong Chonggong Wang Zong wore a dress at noon and entered the Shoucheng room to pay New Year's greetings to Wang Mang, and the mansion also arranged for tomorrow's New Year's celebration.

After the dusk drum sounded, the soldiers of the Wuwei Siming Mansion suddenly came to the door, and Chen Chong, the leader of the Tongmu Marquis, still had a smiling face, but the words that could be said made the eighth Jiao and the five thunders thunder.

"Your Majesty made a book: Gong Chong Gongzong, belongs to the emperor's grandson, the lord is the prince, knows Lu Kuan and other rebellious clans, exiled to Hepu, and communicates with it and secretly communicates."

"There are also maids in the mansion who secretly worship the Wuwei Si Mansion, and the Gong Chonggong conspires against misdeeds in the mansion, and there is a trespass."

"Today, Wuwei Si ordered to enter the house and search, and those who hinder it will be killed!"

Behind Chen Chong was a guard in armor and a knife, and the eighth Jiao could only get out of the way, watching them turn the Gongchong Mansion upside down in a daze.

There are ghosts in the house, it is actually the maid who knelt in the wind with bare legs and holding silk paintings that day, under her guidance, Chen Chong did not waste much effort to find some seals and letters.

Let the family supervisor and the eighth correction be identified, and after Chen Chong looked at the words on the gold seal, he thought that they implied transgression.

The family supervisor and the others were all frightened, but they gritted their teeth and said: "This is just an ordinary private seal, and some auspicious words were written, how can you say that you are arrogating against you?" ”

For example, the sentence "Weizhi crown, save your own summer, be in Nanshan, Zang Boice", and the ordinary officials' family "Jianmingde, hundreds of billions of children, protect ten thousand years, and govern Wuji", are all words of blessing, otherwise Wang Zong would not have put these three seals casually.

Chen Chong had his own explanation, shook his head and said: "The first sentence, how can you explain it?" Happiness, blessing also. The crown is self-contained, and the generation is also attacked. The crown is given to himself, which means that Wang Zong wants to usurp the throne! ”

"As for the second sentence 'Thin Ice in the South Mountain in Summer', it seems to be ordinary, but it is actually more vicious!"

Chen Chong was also born in the Five Classics, and he was still friends with the great writer Zhang Zhu, and quoted the scriptures and classics at his fingertips: "Xiaoya has "The Shi of Jienan Mountain", which satirizes famine, plague, restlessness in all directions and the beheading of the country. The fifth song of the same section, "Xiao Min", satirizes the mediocrity of the king of Zhou, causing the virtuous ministers to have the fear of walking on the ice in the abyss. ”

The second seal "Su Shengbao Ji" is better explained: "After Your Majesty inherits Shengshun, you can be solemn and respectful, and you will be able to stand by the Heavenly Treasure Turtle." Wang Zong wants to follow suit. ”

The third is "Defeng Changtu", Chen Chong said with a smile: "This is Wang Zong's self-proclaimed desire to see the seal with virtue, when Sui Chang is prosperous, and he is covered by the world's books." ”

"All this is very harmful! The meaning of the text is very harmful! ”

The eighth correction was completely stunned and couldn't refute it.

As for the letters, they are the correspondence between Wang Zong and his uncle Lu Kuan's family, who were exiled to Hepu—the other half of the letters, which Chen Chong had intercepted from Hepu a long time ago, and have endured it until today.

Although the above are all ordinary family words, for Wuwei Si Ming Chen Chong, he will be able to find enough reasons to convict him of great rebellion if he writes six lines of words for the most honest and simple person in the world!

And the most critical evidence came from a secret room that even the informant maid didn't know, and Wang Zong's self-portrait was found from it.

In the painting, Gongchong Gongwang Zong is wearing the clothes of the Son of Heaven and the emperor's crown, so imposing!

In this way, the evidence is conclusive, and with the foolish words that Wang Zong said to Wang Mang in Shoucheng's room today, his crime does not even need to be tried.

The only thing Chen Chong needs to consider is how much scope and how many people will be involved in this case?

A hundred, or a thousand.

His duty is to sniff out and eradicate traitors for His Majesty the Emperor, but apart from the main culprits, Chen Chong is also happy to take out some people who are in trouble with the orders of the Five Powers.

For example, several Tai student leaders he wrote down in that day, as well as the culprits who caused Lang Guan and Tai students to besiege Si Ming Mansion, making them have to overturn the case and lose face......

"Fifth Lun."
