48 "Nine Chapters of Arithmetic"

"The long history is going to edict, and the Lady of Cuihua will be given two levels! Order the soldiers who have been in the border for one year to take turns to return to their hometowns and provinces for a month! Husbands and wives who have wives are reunited, and those who have no wives are urged to do their best to get together. Those who get married during the provincial period will be given a piece of cloth as a congratulatory gift for the widow. King Qin said.

Feng Qiji quickly finished writing, used the seal, and immediately sent the horsemen around him to send the horses to the hands of the national lieutenant.

Only then did the woman realize that it was the high-ranking King Qin in front of her, and she immediately burst into tears and laughed, and thanked her with a thousand thanks: "The people's daughter is already satisfied that she can get together with her husband, and she dares to be knighted in vain?" ”

"Thou hast done a great job in thou hast pointed out the faults of the widow in thy words today. You deserve it! King Qin said categorically.

Then the woman was thankful and went away.

"Congratulations! Congratulations, Your Majesty! Montenegro said.

"Where does this joy come from?" King Qin asked.

"This year, let the soldiers return to their hometowns and provinces for a month, and next year tens of thousands, hundreds of thousands of Daqin children will be born, and twenty years later, these children born with Wang En will be an invincible iron army in the world." Montenegro said.

"Today, the widow is gracious to the people of the world, and he will repay the people of the world with his life every day! You can say that again! King Qin said with emotion.

That night, the villagers held a fire to celebrate, and King Qin participated in the celebration with Wang Xiaofei as a Guanzhong businessman, and for the first time in his life, he sang Guanzhong folk songs hand in hand with the farmers, danced together, and drank wine with a large pottery bowl! This night, he is not the King of Qin, he is just an ordinary Guanzhong man, a lover who has just reaped love. Guanzhong folk songs are rough and free, straightforward and sincere, enthusiastic and generous, etc., with strong local characteristics, which make people forget to return.

Until the middle of the night, King Qin sang hoarsely for the first time in his life, and he was drunk when he rarely drank alcohol! It was perhaps his happiest night. And later, when the people in this village knew that the person who drank and sang to their heart's content was King Qin, they boasted about it for several lifetimes! Singing, dancing, and singing wine in a big bowl with King Qin, it is enough to envy the dead when you say that you will go!

This time on the tour, King Qin gained love! Before the Mid-Autumn Festival, Wang Xiaofei was married into the palace with the etiquette of a princess! The entire Qin Palace was full of joy, and even the Empress Dowager Zhao, who had been sick in bed for a long time, suddenly recovered and personally came to Xianyang Palace to give a big gift to the princess.

The three armies also built their own barriers in Zhao and confronted each other with the Zhao army. General Wang Jian strictly ordered that all battalions could only hold on, and those who violated the order were immediately beheaded. Although Li Mu used his troops like a god, in the face of the Qin army's fortress defense line, he could not speak with a strong bow and a crossbow.

"The Qin army is going to use its strong national strength to drag down the Zhao State!" Li Mu sighed impatiently. After two victories over the Qin army in two battles, King Zhao moved Li Mu to Wu Anjun and worshiped the general, which was already the highest achievement of a military general in the Warring States!

"The Qin army has come from afar, and our army is working hard, are you afraid that you can't afford it?" Deputy General Uncle Le said.

"More than 30 years ago, Changping faced off, and today it is repeated. Although I am not Zhao Kuo, Zhao Jun is still Zhao Jun, but Zhao Guo is no longer the Zhao State of the past. The country was in danger, and the king of Zhao and the prime minister should encourage production, buy a large amount of grain from Qi, Chu, and Yan, and send envoys to enlist the support of the other four countries. But now King Zhao is addicted to wine every day, Guo Kai is intoxicated with power and scheming, and he has no way to deal with it, and he has sent people to urge the war again and again, and he has forgotten the pain of Changping! Zhao Guo is already in danger of internal and external troubles. Li Mu said worriedly.

"If it's a soldier-to-soldier general-to-general, we won't necessarily lose. The three-way army of the Qin State entered the Zhao State, and we still have to be distracted to deal with the people in the court, which is really a nest. The deputy general Uncle Le said, "Fortunately, the county guards of all counties understand that this time the Qin State attacked Zhao, it was definitely not a retreat after occupying a few cities, and they all transported the raised grain to the front line!" can barely keep Zhao Jun supported by two porridges a day! ”

"Although Zhao Guo can barely support it now, it will undoubtedly be defeated in the long run, and the only way at present is to get rid of Guo Kai, a big traitor, and force Zhao Wang to move to the throne of Gongzi Jia, so that Zhao can work together and fight with Qin to the end." Li Mu said fiercely.

Zhao Wangyan, the previous monarch of Zhao State, set up Gongzi Jia as the crown prince as soon as he succeeded to the throne, and Gongzi Jia was known as a virtuous name and was very loved by the Zhao people. But the good times didn't last long, and a mixed-race bearded girl advocated prostitution in Handan, which was very gorgeous and caused a sensation in Handan City. At that time, the doctor Guo Kai spent a lot of money to buy this mixed-race prostitute and lured Zhao Wangyan to have a secret tryst. The prostitute Hu is not only extremely gorgeous, but also has excellent kung fu in bed, and King Zhao couldn't stop it, so he took it back to the palace and didn't get out of bed day and night. Soon, the prostitute became pregnant and gave birth to Gongzi Qian. King Zhao was overjoyed, promoted Guo Kai to the doctor, and named the prostitute as the princess. A few years later, under the operation of Guo Kai, King Zhao ignored the opposition of his ministers, abolished Gongzi Jia's crown prince, re-established Gongzi Qian, named Concubine Hu as queen, and Guo Kai as prime minister. In 235 A.D., the king of Zhao collapsed, and he was called Mourning Xiang, and was known as King Zhao Mourning Xiang. The ten-year-old son moved to succeed to the throne of King Zhao, and the great politics of Zhao fell into the hands of the powerful minister Guo Kai. After Guo Kai took power, he took revenge on the ministers who opposed him back then, and reappointed his cronies! I wanted to attack Li Mu several times, but because Li Mu was too famous, and because of Qin's frequent attacks on Zhao, I couldn't find a replacement general for a while, so I gave up!

Li Mu knows this very well, a general who has made countless military exploits for the country must rely on the invasion of the enemy country to survive! was really impatient, so he also secretly summoned Zhao Cong, the king of the plains, and Sima Shang, the commander of the county army, to discuss a coup d'Γ©tat and set up Gongzi Jia as the king of Zhao. However, he was afraid that after the coup d'Γ©tat, the Qin State took advantage of the chaos to destroy the Zhao State, and he became the culprit of the destruction of the Zhao State. Zhao Cong and Sima Shang asked Li Mu to make a decision several times. Li Mudu hesitated and replied: "If you are terminally ill and use fierce medicine, it is very likely that you will die!" Can Zhao Guo stand the fierce medicine? I, Li Mu, want to be the minister of Zhao again, so that I will not be the general of Zhao if I die! ”

Wang Qian, the fake general of the Qin State, is nearly sixty years old, and he has used his troops ruthlessly, and he has never been defeated since he led the troops. This time against Li Mu, both of them are veterans who have won a hundred battles, it can be said that the opponent will meet the good talent, and there is always one who wants to go down the altar of undefeated in a hundred battles, so both of them attach great importance to their opponents. Wang Jian adopted the strategy of defending as the attack, and strictly ordered the three armies to set up a solid camp and hold it firmly! The two armies have been facing off for months, testing the patience of each other and their monarchs.

King Qin still reviews the mountains of Qin folds every day! This year is another bumper harvest year in Qin, the corn harvest in Nanjun has been harvested, and Teng Yue, the county guard, personally inquired about all from sowing to harvesting, and when the corn was ripe, he immediately sent people to load several carts of corn cobs, and sent them to Xianyang day and night.

Zhang Cang stayed closed for several months, concentrating on studying the abacus and Arabic numerals of the Montenegrin Sect, and rearranged the "Nine Chapters of Arithmetic" written by himself, which was finally completed a few days before the Mid-Autumn Festival. Prime Minister Wang Juan attached great importance to this book, not only studied it carefully, but also asked the officials of the Prime Minister's Office to use the method to calculate various data sent from all over the country every day, and confirmed that the abacus was used to calculate and use Arabic numerals, which was fast and accurate. immediately took Zhang Cang into the official to meet the King of Qin. King Qin was looking at the corn cob sent by Nanjun, listened carefully to Zhang Cang's introduction, and also carefully read the "Nine Chapters of Arithmetic" and the abacus. Hearing that the abacus and the Apaib numbers were provided by Montenegro, he immediately summoned Montenegro into the palace.

Lieutenant Wei and Montenegro inspected the training of the lieutenant army together and spoke highly of the changes that have been reborn in the lieutenant army over the past few months. The two of them discussed the current situation of the showdown between Qin and Zhao!

The strength of the two armies is balanced, and when they face off for a long time, their respective national strength and the king's trust in the commander will be the key to victory or defeat! The decisive point of the battle has been shifted from the front to the rear. This is the final conclusion of the two.

At this time, the envoy of the King of Qin came to announce that Black Mountain had entered the palace, and Wei Yu happened to have official business to enter the palace, so the two went together.

Montenegro met with the King of Qin and saluted the Prime Minister Wang Juan.

King Qin held a corn cob in his hand and asked Montenegro: "This is the fresh corn sent to the palace by Nanjun, and the corn has a bumper harvest in Nanjun, do you know how to eat it?" ”

"The king can boil water and eat it. Fragrant and sweet! Montenegro saw that although the corn cob was one size smaller than the later generations, it was about the same, and introduced it to everyone unhurriedly.

The king of Qin asked the imperial chef to do some, so that everyone could repay the freshness, and said to Montenegro: "Zhang Cang wrote this book "Nine Chapters of Arithmetic", the widow took a cursory look at it, it is very good, very practical, and can be used as a practical book that officials must learn, he said that the Arabic numerals and abacus in it are from your handwriting, where did you learn it?" ”

King Qin asked, and Montenegro had no choice but to reply: "The abacus is something I realized when I saw Lord Zhang Cang using a calculation chip, and I got it by restructuring it." Arabic numerals were learned from Hu Shang when I was in Shangjun, and I think this way of writing is quick and clear to recommend to Mr. Zhang. ”

"It seems that you also have a large share of the credit for the book "Nine Chapters of Arithmetic"!" King Qin said with a smile.

"When I met Master Zhang a few years ago, he had already worked hard for several years on this book, and I just made some suggestions from it, in fact, I don't even know how to use the abacus now, how dare I be greedy." Montenegro said.

"Zhang Cangxian's "Nine Chapters of Arithmetic" is meritorious, and he is given the Zuo Shu Chief, and the Taicang Order is the office!" King Qin immediately rewarded Zhang Cang. The Taicang Order is an official position under the internal history of Zhisu and responsible for managing the country's money and grain, and is regarded as the successor of the internal history of Zhisu, and his future is unlimited.

Zhang Cang immediately thanked him.

At this time, the cooked corn cob was also served, and the King of Qin ordered Zhao Gao to compensate everyone for the freshness!

Everyone took a golden corn cob that was still hot, and when they bit it, it was really fragrant, sweet, and full of elasticity. All of them are praised. In this era, sweets are very rare, as long as they are sweet, they are luxuries. Montenegro is also the sweetest food I've eaten in more than a year!

"This corn is so expensive now! Teng Yue reported that someone on the black market had already offered a gold and a corn cob. Sending these three carts of corn cobs is worth 30,000 gold! King Qin said, "What do you think about this?" ”

Wang Wanyakou was no longer as good as the young man, and most of the roots had not been eaten, so he hurriedly said: "Don't sell it, sell it to the other five countries, they will also plant it in the coming year, this is tantamount to an enemy!" ”

"No matter how you prevent it, those businessmen will do everything possible to buy seeds, and if you can't prevent it, it's better for us to exchange food with Wei, Qi, and Chu! In this way, we will not have to worry about military rations next year, and Zhao will not be able to buy cheap grain from other countries, which will be of great benefit to us. Wei Yu suggested.

"We can learn from Goujian, the king of Yue, to steam the corn half-ripe, dry it, and then exchange it with merchants from other countries for grain, and exchange a piece of corn for a stone of rice. Qichu's grain and rice will definitely be transported to Nanjun and Sanchuan County in exchange for corn, and we can also save people's labor. Maybe another year will be available next year. Montenegro suggested.

"Okay, let Teng Yue leave enough seeds, and the rest will all be steamed and exchanged for grain with the merchants of the five countries!" King Qin made a quick decision.

"Your Majesty, such delicious corn, why don't you let Teng Yue transport some to Xianyang, and the king can pay more?" Wang Juan suggested.

"I paid it today, just wait for next year! I make sure everyone has enough to eat! Some of the three cars will be left for the Queen Mother, and the rest will be sent to Wang Qian's army to comfort the soldiers in front! King Qin said.

Everyone was moved! "With a monarch like this, we are very lucky, and Qin is also very lucky!" Wang Juan said movingly.

"Montenegro offers water wheels and corn, which has made great contributions to the Qin State, and the first level of Pujue is made for the less, and the gold is given 100 yi!" King Qin suddenly gave Montenegro a big reward.

Montenegro was stunned for a moment and accepted the reward. From the right to the less, just like the deputy department to the main part of later generations, many people are stuck there for a lifetime and cannot be overcome! Stepping over, the future is bright.

With the replacement of the "Right Mansion" in Montenegro's family with "Shaoshang Mansion", the two poems "Biansai" and "Autumn Thoughts" also spread in Xianyang. The happiest was the mother, in addition to the one hundred and fifty pounds of gold, mainly many high-ranking officials and noble women came to visit her, and asked about the marriage in Montenegro, without exception, there was a woman of the same age in the family! In a few days, there were sixteen. The mother was dazzled, and felt that all of them were good, and it was enough to marry any family to honor the ancestors. In the end, he simply suggested that Montenegro said: "Just marry them all." Look at the Zhang Cang who often comes to you these days, he is not as tall as you, his mother-in-law and aunt are fourteen years old, only twenty-four years old, and his sons and daughters are ten! ”

Montenegro couldn't laugh and cry, and replied: "My dear mother! I've made an oath to God! The world is not unified, and Montenegro will never marry a marquis! Because God saw your son's sincerity, he was promoted so quickly in the past few years. If I marry a daughter-in-law now, won't I lose my trust in God and will be struck by lightning! ”

The mother was the most superstitious, complained about Montenegro a few words, and did not mention the marriage again.

After Zhang Cangshu became a book, he often came to Montenegro to discuss arithmetic, and Montenegro was willing to teach him all the formulas, theorems, and laws that he could remember! Montenegro sincerely hopes that the first author in the world to write a professional mathematical book can master more mathematical knowledge in later generations and make more contributions to this era! Zhang Cang also began the creation of the second part of his "Nine Chapters of Arithmetic".

The days flew by, and Xianyang ushered in the first year of October and the first heavy snow of this winter. Montenegro sent a large number of lieutenant troops to investigate every corner of Xianyang! The first is to prevent heavy snow from crushing houses and killing people. The second is to pay attention to the fact that there are many people who come from afar, who are reluctant to stay in the hotel, and are frozen to death in the corner in the middle of the night. Many old houses look wrong, but the beams and columns are emptied by termites, and the snow immediately collapses and crushes people to death every year. Fortunately, Montenegro investigated in time and found many hidden dangers in advance! Some people from the countryside who tried to spend the night in the corners were also persuaded to stay overnight in the cheap hotel Odori Suke. Ensure that the world's largest capital, with a population of more than 600,000, has no accidental deaths in this heavy snowfall.

On the third day of the first year of the year, Montenegro changed into civilian clothes and asked Zhang Jin to follow him with a few short soldiers. came to the lieutenant's mansion, and after Zhang Jin came back, Zhang Jin served as the commander of the short soldier again, and the black slave went to be Meng Hao's deputy general of the secret guard.

"In the first two days of the year, is there anything going on?" Montenegro casually asked the officials on duty, and if there was a really big matter, they would send someone to inform Montenegro as soon as possible.

"It's all fine, only a few houses have collapsed due to the snow, and we have already informed the people inside to evacuate, and there are no injuries. It's that Li Zheng from Dongcheng came to report that a family of four burned carbon to keep warm at night and was poisoned by cigarettes. Someone has been sent to inform the Xianyang government! The official on duty said.

"Let's go, let's take a look!" Black Mountain said, taking Xiao Hei and a few short soldiers towards Dongcheng. Every time he saw Montenegro go out, Xiao Hei followed Montenegro closely, and the group walked eastward through Xuanwu Street to the most densely populated east. There are many alleys here, and many small courtyard houses are home to more than 10 families. They were all nearby vendors and peasants living in the city. This land, which only accounts for 30% of Xianyang City, lives 80% of Xianyang's population, and is the key area inspected by the lieutenant army. Every year, no matter how much publicity and prevention is carried out, several families die of poisoning while burning charcoal for heating.

It didn't take long to come to the place where the accident happened. The surrounding area was full of onlookers, more than a dozen soldiers from the Lieutenant's Mansion maintained order, and the corpses had been carried outside by the officers of Xianyang Mansion and covered with white cloth!

"Disperse the onlookers!" Montenegro ordered the soldiers, and asked him again, "What is the result?" ”

The soldiers quickly drove the onlookers away, and the venue suddenly became empty.

He knew Montenegro in the last case, and he didn't dare to slack off, so he hurriedly saluted and replied: "There are four corpses, all of which are red, with no traces of external injuries and fights, and shallow corpse spots. It can be concluded that they all died of charcoal poisoning around the third watch last night. ”

Montenegro entered this Erjin courtyard, cleaned up quite neatly, because the weather was too cold, a family of four lived in a room with a big kang, burning coal for heating. There is a chimney at the end of the kang to exhaust the smoke out of the house.

"Are there any living people in this house? Call me for it! Go and check the smoke vent carefully! Montenegro ordered.

After a while, two middle-aged maids, a man and a woman, were brought over! I look nervous! They saluted separately.

"You don't have to be nervous, it's just a routine question! What do you two do? What is the relationship with this family? Montenegro asked.

"The two of us are servants of this family. It's been less than a month since I arrived, and the master's bedroom usually doesn't let us in! We really don't know why everyone was fine a few days ago, but today it's gone! The old man replied, unable to hide the fear in his heart!

"You don't have to be afraid, although Qin's law is strict, it will not hurt innocent people. What does your master do? Was it you who first discovered it? Montenegro asked again.

"The master and his wife are the servants of the prince's mansion, we are usually only responsible for housework and taking care of the two children, and the master and his wife have to go to the prince's mansion every hour! Today I saw that they didn't get up, and I was afraid that they would knock on the door and call them before they could make it! As a result, there was no reaction for half a day, and the doors and windows were inserted backwards and couldn't get in! I thought to myself that something must have happened, and I didn't dare to smash the door open, so I went to call for Master Lizheng to help! After Lord Li Zheng pried open the door, he found that all four of them were dead, so he went to report to the official. The old man calmed down a little and said.

Montenegro knew that the Qin State did not have a prince, and the prince's mansion that the old man said should be the mansion of the proton prince Dan of the Yan Kingdom. Then he said to the old man and his wife, "Very good! Go down first! Waiting for the summons from the government! Montenegro said to his men again: "Call Lizheng to come over for a while, how is the flue checked?" ”

"General, the flue is very normal, there is no blockage, and no suspicious footprints have been found around!" Zhang Jin replied.

The chimney part of the house is straight up and leans out of the side of the house until it reaches the roof, which prevents rainwater from flowing in backwards on rainy days. Montenegro commanded: "Remove the chimneys on top and check them!" ”

He opened his mouth and muttered, "Is that necessary?" "But I obeyed the order and let people do it!

A middle-aged man in a black kudzu robe walked over, bowed his hand to everyone, and said, "I'm a local lizheng, which adult is looking for me?" ”

"When did the people in this house start living here? When did you find the deceased? Montenegro asked directly.

Li Zheng saw that this young man was dressed in civilian clothes, and he didn't know what an official was, but he was obviously the head of this group of soldiers. He didn't dare to slack off, and replied: "This family is the servants of Prince Yan's Dan Mansion, and they just bought this house less than two months ago, and they moved in on August 28, and those two servants came on August 26!" These are available in the registration file. In the morning, the manservant came to me and said that the master's family did not respond to any calls, and that something was going to happen. I brought two Ridding with me and pried open the door, only to find that they had been poisoned by charcoal and died! ”

"When you go into the house, do you smell of smoke?" Montenegro asked again.

"The smell of smoke is a little louder than usual, I asked everyone to open the doors and windows to ventilate, and then go in to check, and report to Xianyang Mansion!" Rizheng replied.
