Lao Qin's stubbornness cannot be changed by Li Chengqian in a few words, this is like the battle between the sweet party and the salty party, so the helpless Royal Highness the Crown Prince indiscriminately stuffed Lao Qin with two cans of milk powder, and ended these conversations hastily.

When Lao Qin left, only the old eunuch Fang was still sitting in the tent in a daze, and Li Chengqian walked over very curiously: "Old Fang, what are you muttering?" Lost money? ”

The old eunuch Fang was disturbed by Li Chengqian, and raised his head with a bitter face and said: "Your Royal Highness the Prince, you, you have said too many things tonight, the old minister can't remember, how can you explain to Your Majesty when you go back!" ”

"Can't remember?" Li Chengqian recalled some of the things discussed at night, looked at the old eunuch Fang and said with a smile: "When you go back, you will tell my father that you can only set the price of three things, felt, woolen materials, carpets, you always remember the price of these three things, right?" ”

"His Royal Highness the Prince, if you don't go over with the old minister, the old minister really doesn't dare to return to His Majesty like this!" Old Eunuch Fang cried and said depressedly.

You must know that Li Er's purpose in letting him come over is not just to listen to the price, but also to learn the dialogue during the conversation, such a complex set of dialogues, if you let the old eunuch Fang learn it, it will indeed be difficult for him, after all, he is not like Li Chengqian, he has the ability to never forget and never forget.

"Alas, okay, okay, don't cry and lose your face, you don't know and think I'm bullying you." Li Chengqian was very considerate and agreed to the old man's request, and said that he was willing to go with him to the old man to explain the events of the evening.

And Li Chengqian really needs to explain to the old man what happened at night, after all, this must involve a group of old people in the Tiance General's Mansion at the beginning, and if he doesn't talk to the old man, he is afraid of leading to some bad thoughts of Lao Li.

In these years, it is not easy to do any profession, especially the high-risk profession of the prince, so you must be very careful.

Following the old eunuch Fang, Li Chengqian came to the old man's tent with a can of milk powder.

"It's so late, why haven't you slept yet? What are you doing here? Li Er was already preparing to rest at this time, and when he saw Li Chengqian coming over, he asked suspiciously.

What to do? Li Chengqian glanced at the old eunuch Fang, and wanted to say: Your useless subordinates don't understand what to learn, I'm here to help him.

However, when the words came to his mouth, he swallowed them back, cleared his throat and said: "Erchen has some grassland specialties here, and I will invite my father to taste one or two." ”

"A prairie specialty? Is that the thing in your arms? Li Er pointed to the can of milk powder that Li Chengqian was holding in his arms and asked.

"This is called milk powder, which is refined from fresh milk on the grassland, and although the taste is not as good as fresh milk, it is also a rare and excellent product." Li Chengqian put the jar on top of the table on the side and opened the lid to let the old man see more clearly.

As an emperor, everyone is basically delusional, and although Li Er is bolder, he is no exception. So looking at the white powder in the jar, Lao Li also had a trace of hesitation, and the first thing that came to mind was almost the same as Lao Cheng - arsenic!

But fortunately, Li Chengqian didn't want the old man to try the taste of this thing, because Lao Li, as the emperor of the Tang Dynasty, can drink human milk at any time even if he wants to, let alone cow's milk and goat's milk, and there is no need to drink milk powder.

So Li Chengqian just wanted the old man to see what the milk powder looked like, and after reading it, he put the lid back on, and then said: "Father, this milk powder is durable and can provide people with a lot of necessary nutrients, so the son thinks that this thing can be used as a supplement to military rations." ”

"It's okay to use it as military rations, but the price is ......" Li Chengqian doesn't need to say much about the benefits of dairy products, Li Er naturally knows it, but he is still very worried about the price.

According to Li Chengqian's temperament of being able to sell millions of yuan of wine, Lao Li believes that this milk powder is not expected to be cheap.

"Father, this milk and goat's milk are very cheap, the price purchased by Datang is two and five catties, and one catty of milk powder needs to consume about ten catties of fresh milk to refine, so the cost price of a milk powder is about ten wen."

"Ten wen is not cheap anymore!" Li Er looked at the jar on the table, thought for a while and said, "Even if this thing is me, it can eat two catties in one meal, and the soldiers below are estimated to eat more......"

Li Er was wrenching his fingers and talking, feeling that someone was pulling his clothes on the side, but when he looked back, it was Lao Fang, and he couldn't help glaring at him impatiently, asking him to talk about what he had to do.

Then he said angrily: "Let's be a soldier and eat three catties a meal, that's thirty Wen, Cheng Qian, you take me as a big wrong, right?" ”

"Father, you misunderstood, this thing is not eaten like this." Li Chengqian's handsome face was flushed, and he suppressed the urge to laugh for a long time: "Father, this thing is drunk with water, if you drink two meals a day and drink it every time, it is estimated that you can drink it for about half a month." ”

Drunk? Drink a pound for half a month? Li Er was stunned for a moment, looked back at the old man who was standing with an innocent face, and didn't say a word for a long time.

It's too embarrassing, I don't even know how to eat milk powder and start calculating the economic account, but fortunately, there is no outside in the big tent now, otherwise this face will be lost.

Thinking of this, Li Er took a deep breath, slowly spit it out, glared at Li Chengqian viciously, gritted his teeth and said, "What else, make it clear at one time!" ”

Li Chengqian took two steps back, and then said, "No, that's all." ”

"That's all? So many of you spent the night studying this? Li Er pointed to the milk powder on the table and said angrily.

"There isn't one." Li Chengqian shook his head, pointed to the carpet spread in the old man's tent and said: "Erchen plans to export this to the Western Regions, anyway, that place in Persia is about to be finished, this kind of carpet will only be available in the Tang Dynasty in the future, and it can be sold at a good price in the Western Regions." ”

Hearing the word Western Regions from Li Chengqian's mouth again, Li Er fell into silence for a while, and only after a while did he ask: "Why do you invest so much power in the West?" What exactly do you want from the Western Regions? ”

Relying on his memory, Li Chengqian sketched a map of the territory of the Tang Dynasty on paper with a brush, and then drew a triangle on the west side to represent the Great Qin and other countries, and then drew a duck egg at the bottom left to represent Africa.

Then he pointed to the newly drawn position and said: "Father, the Western Regions is not the end, but a starting point, only by firmly grasping the Western Regions in our hands, we have the ability to break out of a broader space, the Great Qin in the extreme west still has great food, and even further west there are more land and resources ......."
