Prosperous Tang Blood Blade

In the Liangyi Hall of the Taiji Palace, Li Yuan's eyes were bloodshot. Looking at the empty hall, Li Yuan said indifferently: "Since the rise of troops in Taiyuan, the relationship between father and son has long...become a stranger. Dalang Erlang, there is no one Don't worry!"

Pei Ji lowered his eyebrows and said winkingly: "The meat is still rotten in the pot, it won't be cheaper for outsiders."

Li Yuan sighed and said, "Jian Pei, the original imperial decree has been changed, and Chen Ying will be granted the title of General Zuo Wuwei, Chief of the Army and Horses of Lingzhou."

Pei Ji said in surprise: "This is a third-rank real job!"

Li Yuan hesitated for a moment and said, "Mingfa!"

Chapter 91 convinced Xu Jingzong (second update)

Fortunately, the Ministry of Officials did not embarrass Xu Jingzong. With Chen Ying's letter, he went through the entry procedures smoothly. There is an extra copper tooth plate, a green official uniform, and a black soft-footed head.

After taking back his official uniform and Futou, Xu Jingzong couldn't wait to put it on when he returned to the house.When Xu Jingzong, wearing gangster official boots, a green official uniform, and a soft-footed toe, appeared in front of Chen Ying, Chen Ying couldn't help but want to laugh.

The top of the Futou hat in the Tang Dynasty is curved upwards to form a semicircle.Moreover, Xu Jingzong's appearance is not good, wearing an official uniform, he can't help but look mighty and domineering, but more like a rice bag on a big horse monkey.

Marquis of Martial Arts, that is, the original Xu's mansion, it is definitely impossible for Xu Jingzong to live in the original house. Even if Chen Ying is willing to give it, Xu Jingzong may not be willing to live in it.At least Xu Jingzong couldn't do the thing of taking the guest out of the picture right now.At the end of the former Xikua courtyard, it was originally Xu's guest room, but now it is the residence of Shi Xu Jingzong, the governor of Marquis Marquis of Wugong.

Among the three rooms, one is used as a study and utility room, one is opened up as a living room, and the other is used as Xu or Jingzong's bedroom.

Although Xu Jingzong was responsible, when he took office, he took over the account book from Lan Er and carefully reconciled it.

When eating in the evening, Lan'er's mouth was pouted to the sky.

Chen Ying naturally knew that Lan'er was dissatisfied with Xu Jingzong taking her financial power.

Chen Ying said with a smile: "This person can't be idle at all. If Xu Jingzong continues to be decadent like this, the whole person will be useless. Now find something for him to do, why not do it!"

Lan'er said: "Lang Jun, Lan'er has been in charge of the account these days, but she is very worried, and dare not make any omissions..."

Before he finished speaking, he heard Xu Jingzong's voice from outside the door: "There are no omissions, this is not necessarily true. Not only is there a problem with the accounts of the Hou Mansion, but the problem is not small, it is a total of [-] yuan!"

Hearing this, Lan Er's eyes almost fell off, she stretched out her hand and swore: "Heaven and earth conscience, Lan Er did not dare to be greedy for half a penny. Die badly..."

"You're talking nonsense!" Chen Ying glared at Xu Jingzong and said, "Lan'er, I can trust you!"

Xu Jingzong quickly explained: "Miss Lan'er, don't misunderstand, it's not that Miss Lan'er is greedy for ink, but those tricky officials who deceive Lord Hou!"

Hearing this, Lan'er and Chen Ying looked at each other, and Chen Ying asked, "What's going on?"

Xu Jingzong said indignantly: "These gangsters are really hateful!"

Xu Jingzong took the account book and pointed it out to Chen Ying one by one.

The salaries of officials in the Tang Dynasty were generally divided into three types: salary, salary, and job title. Of course, these three types of salary were generally not fixed. Officials of the same level had different titles and whether they had honorary officials or not.For example, Chen Ying is now an honored officer general (both the upper guard), which is a third-rank honorary officer, so Chen Ying enjoys the treatment of an official third-rank official and the sixth-class founding marquis.

Chen Ying's salary includes the annual record of Yongye land, which includes job title land and title land. Chen Ying, a martial arts marquis, owns 25 Qing Tian, ​​plus nine career lands, in fact, he owns [-] Qing (two [-] mu), this field can be passed on to descendants, but the level of income depends on the tax set by the officials themselves.

Chen Ying did not formulate the tax and rent of the working land, and the officials in charge took advantage of their positions to collect rent according to the system of [-] taxes and [-] tax. According to this regulation, Chen Ying could receive at least [-] shi of grain.

In fact, Chen Ying looked at it for a long time, but he was still confused, and he didn't find any tricks in it.

Xu Jingzong reminded Chen Ying, and Chen Ying finally understood.Actually.These officials actually collect rents based on millet, but when entering the account, they use chestnut rice to enter the account. The price of grain in Chang'an is two cents more expensive than chestnut per bucket.Nine hundred stone valleys were exchanged for nine hundred stone chestnuts, and the price difference of [-] yuan disappeared.

[-] yuan, that is, only [-] guan, this amount of money is basically a drop in the bucket for Chen Ying.However, the important thing is that this is not a question of more money and less money. Anyone who is cheated by others will definitely not feel happy.

Although the value is not high, her responsibility for dereliction of duty is indispensable.Lan'er blushed immediately, not knowing what was wrong.

Chen Ying immediately picked up a pen and quickly calculated.Arithmetic is a compulsory course in later generations. Basically, most people can calculate addition and subtraction within [-] by heart. Chen Ying recorded the calculated results in Arabic numerals. In just a quarter of an hour, Chen Ying I calculated the entire account book again, except for this method of receiving at a high price and entering at a low price, it was exactly as Xu Jingzong said, with a price difference of [-] Wen.

Xu Jingzong looked at Chen Ying's way of settling accounts. Although it was different from him, it was more than a hundred times faster than him. When Chen Ying changed 18000 to [-], Xu Jingzong admired sincerely: "Master Hou is also a math master?"

Chen Ying said noncommittally: "The study of arithmetic and arithmetic cannot be popular in the world today, and the pedantic scholars in the world denounce it as heresy. How stupid is that, don't you know how important arithmetic is to the national economy and people's livelihood? People stand in the world and act Sitting, sleeping, eating, clothing, and sleeping are all inseparable from this knowledge. If this knowledge can be widely used in the world, the disaster of the chaotic world can be stopped, and the order of the prosperous age can be flourished."

Xu Jingzong nodded deeply and said: "Being an official will benefit one party. If you can't do arithmetic, you can only be a muddled official!"

Chen Yingdao: "Jingzong is also proficient in arithmetic?"

Xu Jingzong said indifferently: "I understand a little, I understand a little. For example, one chicken is worth five, the hen is one, and three is worth three, and the chicken is three, and one is worth one. A hundred chickens are bought for a hundred dollars. Jingzong knew that there were three groups of answers, first, the old man had four, the mother had eighteen, and the young had 78; the second, the old man had eight, the mother had eleven, and the young had 81;

Chen Ying said with a smile: "But I have a method. My husband and I will each come up with a number. If it is less than [-] million or more than [-] million, add, subtract, multiply and divide each time, and finally list the four numbers, okay?"

For calculation experts, the larger the number, the more difficult the calculation, and the slower the calculation speed. Although it is a purely low-level calculation, it takes the operator's memory and proficiency in the use of raising tools into consideration.There is nothing fancy about this kind of competition, nor is it of much value. It is purely a model used by mathematicians to compete with each other.

The cleverness of Chen Ying's proposal is that both sides will each offer an amount of the same order of magnitude, which means that neither side knows the other's number. When calculating in this way, they are afraid that the other party has already calculated it to fool themselves.

Xu Jingzong clapped the table and shouted: "Okay! Okay! This method is fair!"

Chen Ying waved his hand and said with a smile: "Wait a minute, what about winning? What about losing?"

Chapter 92 convinced Xu Jingzong ([-]rd watch)

Actually Xu Jingzong didn't say anything, Chen Ying also knew that Xu Jingzong didn't take Chen Ying's official position as Marquis Marquis Chief Shi seriously. I am afraid there is no possibility of recovery within the year.Only then did he plan to borrow Chen Ying's Chen Mansion to study and accumulate fame.

If other methods are used, Chen Ying really doesn't know how to convince Xu Jingzong, but by using arithmetic, he is unlucky, Chen Ying can completely abuse Xu Jingzong, let alone Xu Jingzong, even in this era, even if you count everyone Probably not Chen Ying's opponent.

But Xu Jingzong didn't know, he knew that Chen Ying was extremely brave, good at commanding the army, and also good at poetry and calligraphy, so to speak both civil and military.However, they didn't know that Chen Ying was actually best at arithmetic.

Xu Jingzong immediately made a final decision and said: "If Lord Hou wins, Jingzong will serve Lord Hou as an ox and a horse for five years!"

Chen Ying said with a smile: "If Mister wins, I will protect you as a fifth-rank official!"

Xu Jingzong's heart moved, and he said excitedly: "Really!"

Chen Ying nodded and said, "Really!"

Xu Jingzong raised his right palm and said, "A gentleman!"

"Crack!" Chen Ying and Xu Jingzong swear by high-fiving: "Come on!"

Chen Ying wrote down "12345678" on the paper and suddenly found that Xu Jingzong didn't know this kind of Arabic numerals, so he rewrote it into 1000 two million three hundred and forty-five thousand six hundred and seventy-eight. "

Of course, adding and subtracting the remaining eight digits will be tricky, even if you use a sixteen-digit calculator, you can't figure it out.No one thought that Xu Jingzong would not show any weakness, and directly wrote "nine thousand five hundred and fourty seventeen thousand eight hundred and twenty six"

Chen Ying smiled, picked up the pen and wrote down the number he just wrote on the paper, then put down the pen, and when he looked up, Xu Jingzong had already moved the straw stick quickly, and had written the number on the white paper. The first line of numbers.Obviously the addition has been calculated.

The speed of Xu Jingzong's calculation was beyond Chen Ying's expectation.Fortunately, mathematics is Chen Ying's strong point. Although Xu Jingzong is fast, he is not slow.Chen Ying wrote down -83072148 casually, and then wrote down 107763504 without any pause.Chen Ying raised his head and found that Xu Jingzong's calculation speed of addition and subtraction was almost the same as his, but only a few breaths slower.

However, Chen Ying also knew that the ancient Chinese calculation method of addition and subtraction was very convenient, but the rules of multiplication and division were relatively complicated (Old Cheng would not know it).

Sure enough, as Chen Ying expected, when Chen Ying wrote down 1177995525256, Xu Jingzong's head was already in a cold sweat. When Chen Ying wrote down the division result, 0.1293854462791 Xu Jingzong directly threw the counting chip.

"Xu admits defeat!"

Chen Yingdao: "This is a big food number, which is very convenient to calculate!" So Chen Ying wrote down the Arabic one to nine and one to nine respectively, and then used addition, subtraction, multiplication and division to perform vertical calculations.

At this time, Chen Ying taught Xu Jingzong patiently, just like teaching elementary school students, and Lan Er also listened carefully.In fact, Lan'er's math foundation is even worse, she can barely add and subtract within a thousand, and she is blinded by addition and subtraction beyond [-].However, Lan'er is also relatively smart, with a strong learning ability, and her acceptance ability is much stronger than that of junior high school students in later generations.
