Seeing everyone's curious eyes, Li Chengqian said weakly: "I used to be a military Sima, so I know some logistics things. ”

Oh...... I see.

Only Zhao Deyan is clear, and Sima in the army may not know this, he must have learned it when he was in the countryside.

"Hay and those things are not worth much, and you can buy ten catties for a penny. But concentrate feed is worth a lot of money, and you can only buy two catties for a penny. ”

Two pounds? So expensive?

In this way, if a war horse eats ten catties of hay a day, plus ten catties of concentrate feed, it will cost six cents? More than anyone spends?

At this time, Niu Jinda's son Niu Xiaohu spoke, "I remember, I remember that my mother complained before, saying that my father's horse ate more than people. ”

Feng Zhidai looked at Zhao Deyan in embarrassment.

Zhao Deyan said seriously: "The real situation is far more complicated than you think. ”

Feng Zhidai saluted respectfully and said, "Please give me advice from Mr. Zhao." ”

Feng Zhidai was originally the private school teacher of Xiaojiazhuang, and he did not shirk at this time, and strode onto the podium, "Maybe the soldiers of Lingnan can fight a war by eating four flax cakes a day, but the soldiers of Chang'an can't, and even more so those who travel thousands of miles north to fight." ”

"Unless the day of the march is to eat dry food, but if you camp and hold on, the food must have a silver standard, the Tang Dynasty is richer than the Turks, and the food is much better, and the standard of ten cents a day for one person."

What??

Ten Wen? So much? That's enough to buy how many flax cakes?

Zhao Deyan glanced blankly, "You know the flax cake." Just drinking water and eating dry food can't fight a tough battle. And after a long time, soldiers will get sick. Once sick, it means losing combat effectiveness, and if multiple soldiers lose combat effectiveness at the same time, it is quite terrible, so often generals and logistics have to work together to calculate food and grass, just to ensure that the combat strength of the troops is not reduced, and they can respond to the battle at any time. ”

Feng Zhidai's old face flushed, "Then ...... the algorithm I just had?"

Zhao Deyan smiled, "You just now, it was purely on paper." ”

Forehead......

Calculated the war budget again in class and concluded that 500,000 taels could not be beaten, and then Zhao Deyan announced that he was going to eat after class.

Where is Feng Zhidai in the mood to eat? I wanted to show my face today, but I didn't expect to be so ugly and embarrassed.

Zhao Deyan patted him on the shoulder and said, "No need to do this, with your level, it is enough to be a gentleman of numbers." But you are the second son of the Feng family, and you may have to lead the troops to one side in the future, so it is best to go to the army for a period of time to train and be grounded. ”

Feng Zhidai nodded heavily, "I understand, the reason why Champion Hou can become Champion Hou is that in addition to his own talent, I heard that he has traveled since he was a child, joined famous teachers to visit Gaoyou, and traveled to all places in Datang. Alas...... I'm not as good as him. ”

Zhao Deyan couldn't help laughing and said, "Are you comparing yourself to him? Whoever compares with that demon in this world is asking for hardship. Let's change someone. ”

……

This class was originally prepared for Xiao Changle, but in the end, the main owner listened to a "streamlined lesson" and ran out in a fit of anger. Xiao Rui couldn't catch up.

"Hey, I'll cook myself at night......" Xiao Rui could only shout from afar, but Xiao Changle didn't reply.

"Are you going home?"

Xiao Changle rode a tiger, turned around aggrievedly and shouted: "I'm a monk!" ”

What? Monk? What do you do as a monk?

"Monk! Oh, my God! Xiao Rui really wanted to cover his eyes, and said in his heart, this kid, how can he think that one is one?

"Is it okay not to leave home?"

Xiao Changle said aggrievedly: "If you don't leave home, are you waiting to be married to Tubo with your relatives?" ”

Xiao Rui persuaded: "Who said that you want to kiss?" My brother-in-law assures you that he will never let you go and kiss. Come back soon. ”

"Liar! Big liar! I don't believe you. ”

Xiao Changle patted the tiger's head: "When you destroy Tubo, I will go down the mountain." ”

Watching the little guy ride the tiger and gallop away, Xiao Rui couldn't cry or laugh, did I get myself into trouble? Your father wants to take you and kiss, what do you rely on me? It is also the emperor's task to destroy Tibet, and you still rely on me?

Xiao Rui went back to Xiangcheng and told him, and Xiangcheng couldn't cry or laugh.

On the contrary, it was another lady, Wei Yanran, who saw a clue, "Husband, do you think it's strange?" ”

"Strange? What's strange? ”

"Why didn't Xiao Changle go to His Majesty to complain, but came to you instead?"

Xiao Rui smiled: "Your Majesty is more strict, this girl is used to sticking to me." ”

Wei Yanran glanced blankly, "Then let me ask you, why is she so sticky to you when others are not sticky?" ”

"Because I've been playing with her, Yan'er, what do you want to say?"

Wei Yanran wordlessly stretched out her hand and pushed Xiao Rui: "You, such a smart person, how can you be an afterthought in this regard?" Judging from my intuition as a woman, Xiao Changle likes you. ”

What?

"Don't make a fuss, how old is she? Do you know what likes are? ”

Wei Yanran turned her head to look at Xiangcheng, "I don't believe you asked Sister Xiangcheng." ”

Xiangcheng's face was complicated and he didn't speak.

Xiao Rui was dumbfounded, "No...... Xiao Changle did say before that he would marry me when he grew up, but that was a child who was ignorant, how is this? Oh, my God! ”

Wei Yanran reminded: "Sister Changle is twelve years old this year, and 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, stop!" Don't say it, if this gets out...... If you marry the three of you, you'll almost die, if you let Your Majesty know? Is that still there? ”

In the afternoon of the same day, the chamberlain Lao Gao came.

Xiao Rui didn't dare to see it, but Xiangcheng came forward to know that it was not the matter that was exposed at all, Lao Gao was purely ordered to take Changle back to the palace.

"The little sister left in the middle of the day. He also said that if he didn't destroy Tibet, he wouldn't go down the mountain. Gao Neishi, you go back to your father and say that we must find a way to persuade the little sister to come back and let him not worry. ”

The waiter laughed and said, "The little princess must have misunderstood." His Majesty sent the old slave to tell Princess Changle that Tubo and his party had given up the plan to make peace and would resign and go back tomorrow. ”

"Oh? Are you sure? How could it be such a big shift? It is said that they have been preparing for a long time. Xiangcheng was puzzled.

"It was Uncle Guo who came forward and persuaded them to understand the situation, so they retreated." Lao Gao explained: "Please tell the princess about Princess Changle, just say that Your Majesty and Niangniang have not seen the little princess for many days, and they miss it very much, so let her go back and see more when she is free." ”

"Well, I'm tired of the high waiter, I will definitely persuade the little sister back."

After sending away the inner servant Lao Gao, Xiangcheng found Xiao Rui, "Okay, don't hide, it's not my father looking for you." ”

Immediately said about Tubo's departure, Xiao Rui muttered: "How can it be so light? There's no reason for that! ”

It is indeed not so light, and before the Tubo people had time to say goodbye to the emperor, someone secretly made an appointment with Lu Dongzan.
