Xue Lang was a happy guest in the Su family, but Pang Qingyun, the general of jinwuwei in Nanya County, frowned because of the three young men who had been taken back. Su Rong said in a deep voice, "Chen Wei, tell me the situation again."

"Here it is

Chen Wei, kneeling on one knee, said, "my humble duty is patrolling the city today. Some people report that someone is trying to shoot the Duke of Changping on the street with his keepsake. The humble official hastened to take people over to check. The two sides of the conflict were Lu Jing and the Duke of Changping County. Lu Jing and his followers have been knocked down by the guards of Changping County. Lu Jing's three men were surrounded by four spirit dogs. Lu Jing held a bow and arrow in his hand, and there were arrows on the ground and on the wall. According to Jiang Xiaowei, who accompanied him to protect Xue Jun Gong, Lu Jing wanted to kill the spirit dog, which led to the conflict between the two sides. "

Pang Qingyun's expression was more serious and confirmed: "so, Lu Jing did open a bow?"

Chen Wei said, "yes. Lu Jing argued that he did not know Xue Jun Gong's spirit dog. He thought that it was the wolf who came out to look for food and hurt people, so he opened his bow and shot him. "

Pang Qingyun snorted coldly and said, "nonsense! Chang'an City, also dare to open a bow! Who gave him the power? Is Lu Jing the guard of Nanya or the forbidden army of Beiya? "

Chen Weitou lowered his voice and said in a low voice: "Lu Jing is the third grandson of Fan Yang's Lu family's four families. It is said that Lu Jing is very popular with his grandmother, so he is quite arrogant."

Pang Qingyun sneered: "arrogant? Why is it better or worse? How dare you open your bow to Changping County? What's more, the saints paid more attention to the Duke of Changping County. Let's not say that the Lu family of Fan Yang, even if he is a descendant of his clan, dare to bow openly to Changping County, the sage will not forgive him! "

Chen Wei replied: "I have heard that Changping County has a righteous younger brother named Jiang Lin, who married the fourth daughter of Su Lun, a doctor of mathematics in the Imperial College of the Imperial College. Lu Jing had taken a fancy to this girl before, and wanted to be employed as Teng concubine, but Su Lun refused. When he sent for a marriage proposal, he was beaten by Jiang Lin

Pang Qingyun asked, "can Jiang Lin be present today?"

Chen Wei said: "general Hui, it is said that Jiang Lin is highly skilled in martial arts and serves as a school captain in Princess Pingyang's army. This time, the Duke of Changping went to Beijing to offer good fortune and was ordered to lead a team to protect the Duke of Changping. Today, the Duke of Changping county is visiting Su's house, and Jiang Lin is naturally present. "

Pang Qingyun had a sarcastic smile on her face: "it's so! Lu is really good at teaching children! However, this is Chang'an, not Fan Yang. When did Lu's prestige spread to Chang'an and to our jinwuwei? "

Chen Wei shrunk and immediately pleaded guilty: "the humble duty is guilty, please punish the general!"

"That's it! You were born in Fanyang and have heard of Lu's reputation for a long time. You will be afraid of Lu. However, this matter is not a matter of Jin Wu Wei's authority, but should be transferred to Chang'an government. I promise you to do a little bit of friendship with your fellow countrymen and tell the people who are in charge of the capital city of Lu. "

Chen Wei immediately gratefully saluted: "humble duty, thank you for your sympathy."

Pang Qingyun said: "you can send someone to wait outside the gate of Huaiyuan square. When the Duke of Changping comes out, you can tell him. Because of the limited authority, Lu Jing and other people have already transferred Jin Wuwei to Chang'an house. As a bitter Lord, Xue Jun Gong can redress the injustice to the governor of Chang'an."

"Here it is

Chen Wei took orders and left.

Jin Wuwei and Chang'an government offices are full of people. What about Xue Lang? He was also a guest in the Su family, discussing Arabic numerals and mathematical symbols with his father and son.

A group of men gathered around a table. Xue Lang took out his pen, and Dr. Su took out his bamboo chips. Xue Lang wrote Arabic numbers against the numbers on the bamboo chips.

Mathematical research in ancient China is very advanced. In the book of nine chapters of arithmetic, there are not only calculation methods of plane geometric area, calculation of fraction, square root, open cube, volume calculation method of solid geometry, tax apportionment, first-order equation, etc., which is a relatively advanced mathematical work in the world.

The only drawback is computing tools. Before the Ming Dynasty, when people calculated, they used bamboo chips. Bamboo chips were engraved with numbers. Therefore, they were also called planning. After the Ming Dynasty, abacus appeared, and abacus gradually replaced calculation.

Xue Lang can't do abacus calculation. In the past, when he calculated, he used either a calculator or a pen and paper method. He is proud of his way of calculation, but his method of calculation is not so fast.

Dr. Su commented from the perspective of a doctor of Mathematics: "Youyang's method is indeed simpler. Even if it is written on the ground without paper, it can be calculated, which is more convenient than bamboo chips."

If you use bamboo chips to calculate, if it is simple, it's OK. If it's more complicated, you have to take a big bag of bamboo chips alone. Comparing with Xue Lang's several figures, it's really complicated.

Several men discussed for a long time, and Su Mu came to urge dinner for three times before planning a group of men to talk about it. Naturally, the food preparation was not as luxurious as that of the princess mansion and the imperial palace. It was only slightly better than the ordinary food, but Xue Lang was very satisfied with it. As a guest, what you do is your mind. Nothing else matters.

It's steamed buns. They're given preferential treatment. Su Mu seems to really like them. She is very generous. She gives a leg of lamb and eats four dogs full of oil. She also wants to add chicken legs to them, which is stopped by Xue Lang -

dogs are similar to people. They can't be too fat. If they get fat, they will get sick. Don't think that dogs won't have diseases like hyperlipidemia and hyperglycemia. Love your dog and be responsible for your dog's health.With the amount of exercise they have now, Xue Lang only feeds them one meal a day. At other times, at most, he gives some fruits or coarse grains to make small nests. He doesn't give much, but he just feeds them a few grains as snacks.

After hearing this, Su Mu nodded in admiration and said, "it turns out that there are many things about keeping dogs. It's no wonder that steamed stuffed buns are so human-oriented. Spirit dogs are spirit dogs, and their rearing methods are different from ordinary dogs."

Xue Lang couldn't help laughing, but he didn't explain. Su Mu thought that she couldn't tell her that baozi were so smart because they passed through.

After feeding, Xue Lang left. Jiang Lin was not at ease. Naturally, he followed him. The Su's father and son felt sorry for Xue Lang's departure, and some of them were still in the air.

When Xue Lang left, Dr. Su reluctantly said, "when Youyang comes back to Chang'an, he will come again. I also want to discuss with Youyang some knowledge of mathematics."

This word seeks Su Mu's big white eye a pair, Xue Lang actually is smiling to agree. Su Ran Ran Ran also came out to see off the guests. He took Jiang Lin and said, "when it's over, don't forget to tell me."

Jiang Lin nodded. Xue Lang pick eyebrows, stay out, ask Jiang Lin: "younger brother-in-law know we have something to do later?"

Jiang Lin was embarrassed and said, "Ranran knows me very well. I'm worried about today's affairs. She sees that she asks me repeatedly. She can't resist, so she tells me all about it."

Xue Lang laughed and didn't mind. He said with a smile: "no wonder some people say that every woman is born Sherlock Holmes. Look at the shape of ah Lin, I have to persuade you that you should be honest in front of your younger brother and sister, and don't do anything sorry for your sister-in-law, or you can't hide it. "

Jiang Lin was flushed with laughter and said angrily, "brother, don't make fun of my younger brother. When my elder brother marries his sister-in-law in the future, I'll see how big brother is."

Xue Lang said: "it will not be as poor as you are."

Jiang Lin said: "I'll wait and see."

"By the way, big brother, what is Holmes

"Er Sherlock Holmes is a very good detective Well, Constable

What was the name of detective in Tang Dynasty?

Xue Lang frowned and thought for a while, until he got on the carriage and didn't come up with a reason when he went to the gate of the square --

"dare you ask, is it the driver of Changping County?"

Out of the gate of Defang, a soldier dressed as a sergeant of jinwuwei came forward to ask questions respectfully. The guard stopped the carriage and said, "yes. What can I do for the guards

The soldier said, "I am ordered by the general of jinwuwei to wait for the Duke of Changping County here, and I am ordered to deliver a message."

"Go ahead, please."

The soldier said: "today, Lu Jing, the son of Lu, once offended the Duke of Changping County. Because the matter is not within the power and responsibility of Jin Wuwei, Lu Jing and others have been transferred to Chang'an government. The magistrate of Changping county can go to Chang'an government to report the cause of the case, so that the governor of Chang'an can decide. "

Xue Lang said in the carriage: "thank you, general. Please give me a message to convey my thanks. There is a guard. "

"I don't dare. I must bring the words of the magistrate to you."

With that, the soldier retired. Xue Lang in the carriage quietly ordered: "go, turn to Chang'an government."

"Here it is

The party went to the government office of Chang'an.
