Lin Lan smiled and said, "Arithmetic can involve agriculture, commerce and industry, and it can involve military affairs and national affairs, and it is not useless as you said, sir." Pen ~ Fun ~ Pavilion www.biquge.info"

"Huh. If it involves numbers, it is forcibly counted as arithmetic, that is, what you are talking about, such as how many acres of land there are, how many people in a battalion...... But are these useful to learn? It's a person who understands, so I said that arithmetic is a primary school, not worth learning, what's wrong? ”

Lin Lan asked: "When Mr. was fighting in the northwest, he was called General Jintang, can there be such a thing?" ”

Chen Zhice brushed his beard and said, "How? ”

Lin Lan shook her head and smiled, "In my opinion, this good name is simply the biggest insult to you. ”

"You don't have a small tone!" Chen Zhice snorted coldly.

"Don't dare. However, according to the shallow view below, there are many skilled craftsmen in Dajing, with excellent crossbows and firearms, and no one can beat the Northwest Army of Dajing a hundred steps away, but Mr. only defended and did not attack back then, and got the name of General Jintang, isn't it laughing at your incompetence? ”

All the beings in the hall were speechless. Is this Lin Lan crazy? How dare you laugh at Chen Zhice so boldly!

Li Long stood up and shouted, "Lin Lan, you are too disrespectful to the old general!" Chen Fuzi fought in the northwest and made meritorious contributions, but now he is retiring and teaching me the way of military strategy, so that I can do better things in the future, you dare to insult the name of the old general! ”

"Brother Li, don't be in a hurry to settle the charges. Barbarian rangers are brave and good at fighting, but after all, they are flesh bodies, arrows and artillery can seriously damage the enemy army a hundred steps away, and they are used to hold the city, of course, it is easy to defend and difficult to attack. That's why I said that this Jintang general is clearly a deliberately sarcastic title for those who compliment the old general. ”

Chen Zhice's eyes fluctuated slightly, perhaps on the way to the west, the most regrettable thing was that he was not able to capture a city and a pool, and only the defensive battle that held Dugu City was worthy of praise.

"You've said so much, what does this have to do with arithmetic?"

Lin Lan walked back to his seat, spread out the proclamation and began to write things.

"Nineteen, I'll sharpen the ink for you." Hou Haomiao saw that Lin Lan was serious, and he also wanted to do what he could.

Soon, Lin Lan wrote something on the four-foot big announcement, walked forward quickly, pasted the announcement on the wall on one side with saliva, and said, "Today, I will help Master Chen wash away this shameful charge." Since there is a connection between military strategy and arithmetic, let's use numbers to speak. ”

According to the record of "The Battle of Dajing", from the fifteenth year of Kangtai to the twenty-third year of Kangtai, it was General Chen who served as the general of the expedition to the west, and led the troops to fight with the enemy more than 370 times. Among them, there were more than 230 active attacks, and the rest were sieges of barbarian invasions. ”

"Have you investigated the old man?"

Lin Lan said: "How dare you? It's just that a few days ago, while reading a book in the academy, I saw your name and studied it curiously. ”

Chen Zhice raised his eyebrows and asked, "But so what?" ”

Lin Lan said: "You listen to my analysis. This barbarian siege weapon is rudimentary, except for a few sneak attacks, the northwest army of Dajing suffered a slight loss, the rest are small victories, and even a few beautiful counterattacks, it is a big victory, and it is precisely because of this that you are called General Jintang. Let's focus on the situation of the more than 230 times that took the initiative. ”

"In the fifteenth year of Taikang, the Northwest Army sent troops more than 80 times according to incomplete statistics, and in the sixteenth year of Taikang, it sent troops more than 60 times...... Twenty years after Taikang, there were only more than ten troop dispatches, and they were all small forces. From the data, it can be seen that the general's desire to make meritorious contributions in the first five years was more urgent, and as for the last few years, he knew that there was no hope of advancing westward, and his will was exhausted, so he only defended but did not attack. ”

"From the point of view of the troop season, Mr. sent troops more than 120 times in spring and summer, and also more than 120 times in autumn and winter, but analyzing the results, from the textual description, in spring and summer, the number of active attacks is much greater than that in autumn and winter. Doesn't the general find it strange? ”

Chen Zhice has never looked at his life's achievements so systematically.

He didn't expect that so much useful information could be derived when a series of data was laid out on paper.

Indeed, a few years before he took office in the northwest, he was indeed more aggressive in using troops, and then because of repeated failures, he also turned to the defensive, and it was also because of this anticlimactic record, and finally he was named "General Jintang" by the newly enthroned emperor, that is, when he made a pilgrimage, which was indeed joking.

That's not the point. After that, Lin Lan listed the data that surprised Chen Zhice. Despite his experience as an Overseer, even he couldn't have imagined that the small victories in the spring and summer were much higher than in the fall and winter!

The synthesis of data set off a terrifying wave in his heart. If we could have seen it early and concentrated the time for the use of troops in spring and summer, it is estimated that there would have been a breakthrough a long time ago!

"This ...... Why is that? ”

Chen Zhice looked at Lin Lan with some excitement, wondering what the reason for this was.

"Wind."

"Wind?" Chen Zhice stood up, seemingly puzzled.

"Southeasterly winds in spring and summer, northwesterly winds in autumn and winter. Arrows, horse foot strength, these are closely related to the wind, plus the northwest autumn and winter wind is cold, the retrograde arrow plus the barbarian horse with the wind, what are the old general's chances of winning? You're losing to the data. ”

When everyone looked at the data on the wall again, they swallowed.

This data is a good illustration of what arithmetic is all about.

Lin Lan took off the white xuan on the wall, handed it to Chen Zhice, and said, "In fact, arithmetic originates from life production, but it is higher than life production. When these digital data are put forward, it will be clear at a glance. Sir, you have been in the northwest for nine years, and you must be experienced in leading troops, but you often ignore some natural laws, and these details precisely determine success or failure. ”

Hou Haomiao had already been dormant by Lin Lan's strength at this moment. This...... This fights the war with data! It is estimated that it is a new concept proposed by Lin Lan!

The generals are good and bad, like Chen Zhice, who does not seek merit but seeks no fault, he is already considered a middle generation, and the most terrible thing is the mediocre talent who buries the lives of soldiers because of ignorance.

However, the data proposed by Lin Lan to manipulate the war can just avoid some hard injuries, such as attacking the enemy in the northwest from a long distance on a strong winter day, which greatly weakens the power of Dajing's crossbows and artillery.

"You must be tempted to ask, this data is a lesson from the past, what can it do for the future?" Lin Lan narrowed his eyes and whispered in his ear: "Master the speed of the wind, the speed of horses and the speed of arrows, precision strikes, distance budgets, all of this, you don't need to rely on personal experience, think about it, are you using arithmetic to fight?" ”

Chen Zhice muttered dumbly: "Use arithmetic to fight ...... war"

This...... Will it work?
