Settled in the Tang Dynasty

Chapter 186 Progress
Xue Lang was happy to be a guest at Su's house, but Nanya Jinwuwei General Pang Qingyun frowned because of the three young men who were brought back, and said in a solemn voice: "Chen Wei, tell me about the situation at that time again. "

"Here!"

Kneeling on one knee, Chen Weidao said: "I was patrolling the city today, and someone with the official token of Changping County reported that someone was going to shoot and kill the Duke of Changping County in the street. I hurriedly took people over to check, and the two sides in the conflict were Lu Jing and Changping County. There are two people from the public. The entourage of Lu Jing and others has been defeated by the guards of Changping County. The three of Lu Jing are surrounded by four spirit dogs. Lu Jing holds a bow and arrow in his hand, and there are arrows shot from the ground and the wall. According to Jiang Xiaowei, who accompanied Duke Xue to protect Duke Xue, Lu Jing wanted to shoot the spirit dog, which led to the conflict between the two sides."

Pang Qingyun's expression became more serious, and he confirmed: "So, Lu Jing did make a move?"

Chen Wei said: "Yes. Lu Jing argued that he didn't know Xue Jungong's spirit dog, and thought it was a wild wolf that came out to hunt for food and hurt people, so he shot and killed."

Pang Qingyun snorted coldly, and said: "Nonsense! In Chang'an City, he dares to shoot his bow indiscriminately! Who gave him the power? Is Lu Jing the guard of the southern yamen or the forbidden army of the northern yamen?"

Chen Wei lowered his head, and said in a low voice: "Lu Jing is the third grandson of the fourth family member of Fan Yang's Lu family. I heard that he is very popular with his grandmother, so he is a bit arrogant."

Pang Qingyun sneered: "Arrogance? How can there be no distinction between good and evil? How dare you open your bow to Changping County? Why don't you know that the saints have a lot of care for the Duke of Changping County, let alone Fan Yang Lu, even if he is a son of the clan, he dares to show his bow to Changping County The sage will not spare those who open their bows!"

Chen Wei replied: "I have heard that there is a brother-in-law of Changping County, named Jiang Lin, who is married to the fourth daughter of Su Lun, a doctor of mathematics in the Imperial Academy. Lu Jing had taken a fancy to this woman before, and wanted to hire her as Teng's concubine. He was rejected by Su Lun, and was beaten up by Jiang Lin when he sent someone to propose marriage."

Pang Qingyun asked: "Is Jiang Lin here today?"

Chen Weidao: "General, I heard that Jiang Lin is highly skilled in martial arts and served as a lieutenant in Princess Pingyang's army. This time the Duke of Changping County came to Beijing to offer auspicious auspiciousness, and was ordered to lead a team to protect the Duke of Changping County. Today, the Duke of Changping County is going to visit the Su family. , Jiang Lin is naturally present."

Pang Qingyun showed a sarcastic smile on his face: "It's so! Mrs. Lu is really good at teaching her children! However, this place is Chang'an, not Fan Yang. When did the prestige of Mrs. Lu spread to Chang'an and to my Jinwu Guard?" gone?"

Chen Wei flinched, and immediately pleaded guilty: "I am guilty of a lowly position, please punish the general!"

"That's all! You were born in Fanyang, and you have heard Lu's reputation for a long time, so you will be afraid of Lu. However, this matter is not within the purview of the Jinwu Guard, and it should be handed over to Chang'an Mansion. This general promises you to show your fellowship to the The person in charge of Lu's capital will let you know."

Chen Wei immediately saluted gratefully and said, "Thank you, General, for your compassion."

Pang Qingyun said: "You send another person to wait outside the gate of Huaiyuanfang. When Changping Jungong comes out, you can tell him that because of limited powers, Lu Jing and others, the Jinwu Guard has been handed over to Chang'an Mansion, and Xue Jungong is the master of suffering. , you can seek grievances from the Governor of Chang'an."

"Here!"

Chen Wei took the order and left.

A group of people from the Jinwu Guard and the Chang'an government office turned their backs on their backs. Where is Xue Lang?He was still a guest at Su's house, discussing Arabic numerals and mathematical symbols with Su's father and son.

A group of men surrounded a table, Xue Lang took out a pen, Dr. Su took out a bamboo chip, Xue Lang wrote Arabic numerals according to the numbers on the bamboo chip.

Mathematics research in ancient China was very advanced. In the book "Nine Chapters of Arithmetic", there are not only the calculation of plane geometric area, the calculation of fractions, the square root, the cubic root, the volume calculation method of solid geometry, tax allocation, and linear equations, etc. Computational methods are relatively advanced mathematical works in the world.

The only downside is the calculation tool.Before the Ming Dynasty, when people calculated, they used bamboo chips, and the numbers were engraved on the bamboo chips, so they were also called calculations.After the Ming Dynasty, the abacus appeared, and the method of abacus calculation gradually replaced the calculation.

Xue Lang doesn't know how to calculate with abacus. In the past, when he calculated, he either used a calculator or directly calculated with pen and paper.In terms of mathematical knowledge, there is nothing to be proud of compared with the ancients. However, in terms of calculation methods, his method takes advantage of the convenience of writing, and the calculation is faster.

Dr. Su judged with the eyes of a doctor of mathematics: "Youyang's method is indeed simpler. Even if you don't use paper, you can still calculate it when you write it on the ground. It is more convenient than bamboo chips."

If it is a simple calculation using bamboo chips, it is okay, but if it is a more complicated calculation, you need to bring a big bag of bamboo chips alone, and compared with Xue Lang's few numbers, it is indeed much more complicated.

Several men discussed for a while, and Su's mother urged her to eat three times before she decided to discuss with a group of men.Naturally, the food preparation was not as luxurious as the princess mansion and the royal palace, but it was slightly better than ordinary meals, but Xue Lang ate very satisfied.What you do as a guest is your heart, and nothing else matters.

But Baozi and the others received preferential treatment.Mother Su seemed to really like them, one of them was very generous and gave a leg of lamb, which made the mouths of the four dogs drip with oil, and Mother Su wanted to add chicken legs to them, but Xue Lang stopped it——

Dogs are the same as humans. They should not be too obese. If they are fat, they will get sick. Don’t think that dogs will not suffer from diseases such as hyperlipidemia and hyperglycemia.If you love dogs, you are responsible for their health.

With the current amount of exercise of Baozi and the others, Xue Lang only feeds Baozi and them once a day, and other times, at most, they are given some fruit or small buns made of whole grains, not much, but just as a snack. grain.

After hearing this, Mother Su nodded in admiration and said, "It turns out that there are so many things to pay attention to in raising a dog. No wonder Baozi is so human. A spirit dog is a spirit dog, and the way of raising it is different from ordinary dogs."

Xue Lang couldn't help laughing, but he didn't explain, letting Su's mother think that she couldn't tell Su's mother that Baozi and the others were so smart because of time travel.

After feeding, Xue Lang left.Jiang Lin was worried, so he naturally followed him.The Su family's father and son said goodbye to Xue Lang, it was a pity, and there was a feeling that they still had something to say.

When Xue Lang said goodbye, Dr. Su still reluctantly said: "When Youyang comes to Chang'an again, I will definitely be a guest again. I also want to discuss with Youyang about mathematics."

These words made Su's mother roll her eyes, but Xue Lang agreed with a smile.Su Ranran also came out to see off the guests, pulled Jiang Lin and said, "The matter is over, don't forget to ask someone to tell the servant."

Jiang Lin nodded.Xue Lang raised his eyebrows, and after he came out, he asked Jiang Lin: "Siblings know we have something to do later?"

Jiang Lin said embarrassingly: "Ranran understands me very well. I am concerned about today's affairs. She saw it and asked me repeatedly. My little brother couldn't stand it, so I explained everything!"

Xue Lang laughed out loud, not minding it at all, and said with a smile: "No wonder some people say that every woman is a natural Sherlock Holmes. Looking at your current appearance, Ah Lin, I have to advise you to be more honest in front of your siblings. Don't do anything to offend your younger siblings, otherwise, you won't be able to hide it."

Jiang Lin blushed from the laughter, and said resentfully: "Brother, don't make fun of my younger brother. When my elder brother marries his sister-in-law in the future, my younger brother will see how my elder brother is doing."

Xue Lang said: "It must not be as pitiful as you."

Jiang Lin said: "I will wait and see, little brother."

Finished and asked: "By the way, big brother, what is Sherlock Holmes?"

"Uh... Sherlock Holmes is a very good detective... um, a detective?"

What was the name of a detective in the Tang Dynasty?
Xue Lang frowned and thought for a while, until he got into the carriage and reached the entrance of the workshop, he didn't think of a reason——

"Dare to ask, but is it the driver of the Duke of Changping County?"

When he came out of Defang Gate, a soldier dressed as a Jinwu Guard came forward to ask questions respectfully.The guard reined in the carriage and said, "That's right. Dare I ask the guard what's the matter?"

The soldier said: "The young one was ordered by the Great General of Jinwuwei to wait here for the Duke of Changping County, and was ordered to pass on a message."

"please say."

The soldier said: "Today, Lu Jing, a son of the Lu family, offended the Duke of Changping County. Because the incident was not within the responsibility of the Jinwu Guard, Lu Jing and others have been handed over to the Chang'an government office. The Duke of Changping County can go to the Chang'an government office to report the incident. , so that the governor of Chang'an can decide."

Xue Lang said in the carriage: "Thank you, General, please ask the guards to bring me a message to convey my thanks. I have the guards."

"Don't dare, the young one must bring the words of the county magistrate."

After speaking, the soldiers left.Xue Lang calmly ordered in the carriage: "Let's go, transfer to Chang'an government office."

"Here!"

A group of people went to the Chang'an government office.
