Seeing everyone's curious eyes, Li Chengqian said weakly: "I once served as a Sima in the army, so I know some logistics."
Oh I got it.
Only Zhao Deyan knows this, and the Sima of the army may not know this either. He must have learned it when he was living in the countryside.
"Hay is not valuable, and one penny can buy ten kilograms. But concentrated feed is valuable, and one penny can only buy two kilograms."
Two pounds? So expensive?
So, if a war horse eats ten kilograms of hay a day, plus ten kilograms of concentrated feed, it will cost six pence? Spend more than anyone else?
At this time Niu Jinda's son Niu Xiaohu spoke, "I remembered that my mother complained before, saying that my father's horse ate more than people."
Feng Zhidai looked at Zhao Deyan awkwardly.
Zhao Deyan said seriously: "The real situation is far more complicated than you think."
Feng Zhidai saluted respectfully and said, "Please give me some advice, Mr. Zhao."
Feng Zhidai was originally a private school teacher in Xiaojiazhuang. He did not refuse at this time and strode up to the podium. "Perhaps the soldiers in Lingnan can fight by eating four sesame cakes a day, but the soldiers in Chang'an cannot. They have to travel thousands of miles north." Not even those who go up to fight."
"Unless you eat dry food on marching days, when you set up camp and stick to it, the food must have a monetary standard. The Tang Dynasty is richer than the Turks, and the food is much better. The standard is ten cents a day for one person."
What? ?
Ten articles? so much? How many sesame cakes are enough to buy?
Zhao Deyan rolled his eyes and said, "You know flax cakes. You can't fight a tough battle just by drinking water and eating dry food. And soldiers will get sick over time. Once they get sick, it means losing their combat effectiveness. If multiple soldiers lose their combat effectiveness at the same time, then It is quite terrifying, so the general and the logistics often have to work together to calculate the food and fodder, just to ensure that the combat effectiveness of the troops is not reduced and they can respond to the battle at any time."
Feng Zhidai blushed, "Then the algorithm I just used..."
Zhao Deyan smiled, "What you just said was just talking on paper."
Forehead……
After recalculating the war budget in class, Zhao Deyan concluded that five hundred thousand taels would not be enough to sustain the war. Then Zhao Deyan announced that get out of class was over and he was ready to eat.
How could Feng Zhidai be in the mood to eat? I wanted to show my face today, but I didn't expect it to be so ugly. I was so embarrassed.
Zhao Deyan patted him on the shoulder and said: "You don't have to be like this. With your level, it's enough to be a mathematician. But you are the second son of the Feng family, and you may lead troops to control one side in the future, so it's best to join the army." Practice for a period of time and get grounded.”
Feng Zhidai nodded heavily, "I understand. The reason why the Champion is able to become the Champion is that, in addition to his own talent, I heard that he has been traveling since he was a child. He has visited famous teachers and friends, and has visited all the places in the Tang Dynasty. Place. Alas...I am not as good as him."
Zhao Deyan couldn't help laughing and said: "Are you competing with him? Whoever competes with that monster in this world is asking for trouble. Let's find someone else."
…
This class was originally prepared for Xiao Changle, but in the end the principal listened to a "streamlined class" and ran out in anger. Even Xiao Rui couldn't catch up.
"Hey, I will cook tonight..." Xiao Rui could only shout from a distance, but Xiao Changle didn't even look back.
"Are you going home?"
Xiao Changle rode on the tiger, turned around and shouted aggrievedly: "I am a monk!"
What? Become a monk? What do you do as a monk?
"Monk! Oh my god!" Xiao Rui really wanted to cover his eyes, thinking to himself, how could this kid think so often?
"Is it okay not to become a monk?"
Xiao Changle said aggrievedly: "If you don't become a monk, are you waiting to be married off to Tibet?"
Xiao Rui advised: "Who said I want you to get married? My brother-in-law promises you that he will never let you get married. Come back quickly."
"Liar! Big liar! I don't believe you."
Xiao Changle slapped the tiger on the big head: "I will come down from the mountain after you destroy Tubo."
Seeing the little guy riding on the tiger and flying away, Xiao Rui couldn't laugh or cry. Did I get myself into trouble? Your father wants to marry you, what do you want from me? It is also the emperor's task to destroy Tubo. Do you still rely on me?
Xiao Rui went back and told Xiangcheng, and Xiangcheng didn't know whether to laugh or cry.
On the other hand, another lady, Wei Yanran, saw some clues, "Husband, do you feel strange?"
"Strange? What's strange?"
"Why didn't Xiao Changle go to His Majesty to complain, but instead came to you?"
Xiao Rui smiled and said: "Your Majesty is quite strict, this girl is used to clinging to me."
Wei Yanran rolled her eyes, "Then let me ask you, why is she so clingy to you when she's not clingy to others?"
"Because I have been playing with her, Yan'er, what exactly do you want to say?"
Wei Yanran wordlessly reached out and pushed Xiao Rui: "You, you are such a smart person, how come you are so late-minded in this regard? Based on my intuition as a woman, Xiao Changle likes you."
What?
"Stop making trouble, how old is she? Does she know what liking is?"
Wei Yanran turned to look at Xiangcheng, "If you don't believe me, ask Sister Xiangcheng."
Xiangcheng's expression was complicated and he said nothing.
Xiao Rui was dumbfounded, "No... Xiao Changle did say before that he would marry me when he grew up, but that was because he was a child and was ignorant. What's wrong with this? Oh my God!"
Wei Yanran reminded: "Sister Changle is already twelve years old this year. Among the people, many women can get married at the age of thirteen. Do you still think she is ignorant?"
Xiao Rui waved his hand to stop Wei Yanran, "Stop it, stop it! Don't say it anymore. If this spreads out... I will almost die if I marry the three of you. What if His Majesty finds out? Is that okay?"
That afternoon, the chamberlain Lao Gao came.
Xiao Rui felt too guilty to dare to see him, but it was only when Xiangcheng came forward that he found out that the matter was not exposed at all, Lao Gao was simply ordered to take Chang Le back to the palace.
"My little sister left in anger at noon. She also said that she would not go down the mountain until Tubo was destroyed. Gao Chamberlain, please go back to your father and say that we will find a way to persuade your little sister to come back and tell him not to worry."
The chamberlain Lao Gao said with a smile: "The little princess must have misunderstood. Your Majesty sent the old slave here just to tell Princess Changle that the Tubo people have given up on the marriage plan and will say goodbye tomorrow and go back."
"Oh? Really? How come there is such a big change? It is said that they have been preparing for a long time." Xiangcheng was puzzled.
"It was my uncle who came forward and persuaded them to understand the situation, and then they retreated." Lao Gao explained: "Princess, please tell Princess Changle that your majesty and the empress have not seen the little princess for many days, and they are very upset. Missing her, let her go back and visit more when she has time."
"Well, I'm sorry to bother you, Chamberlain Gao. I'll definitely persuade my little sister to come back."
After sending away Lao Gao, the chamberlain, Xiangcheng found Xiao Rui and said, "Okay, don't hide. Father is not looking for you."
Then talking about Tubo's departure, Xiao Rui muttered: "How could it be so easy? There is no reason!"
Indeed, it was not so easy. Before the Tubo people had time to say goodbye to the emperor, someone secretly made an appointment with Lu Dongzan.
