Lao Qin's stubbornness cannot be changed by Li Chengqian's words. It is like the battle between the sweet party and the salty party. So the helpless Prince gave Lao Qin two cans of milk powder randomly and ended the conversations hastily.

When Lao Qin left, only the old eunuch Fang was still sitting in the tent, muttering words in a daze. Li Chengqian walked over curiously: "Lao Fang, what are you talking about? Did you lose the money?"

Old Eunuch Fang was disturbed by Li Chengqian and looked up with a bitter face and said, "Your Highness, you, you have said too much tonight. The old minister can't remember it. How can you explain to Your Majesty when you go back!"

"Can't remember?" Li Chengqian recalled some of the things he discussed in the evening, looked at the old eunuch Fang and said with a smile: "When you go back, you told my father that you only set the price of three items, just feel, tweed materials, carpets, and the prices of these three items, right?"

"Your Highness, why don't you go there with the old minister? I really don't dare to report to Your Majesty like this!" Old Eunuch Fang said depressedly.

You know, the purpose of Li Er letting him come here is not just to listen to the price, but also to learn the dialogues. If such a complex set of dialogues are asked to be learned by the old eunuch Fang, it would be difficult for him. After all, he is not like Li Chengqian, who has the ability to remember everything he sees and never forget everything he hears.

"Oh, okay, okay, don't be sad. Those who don't know will think I've bullied you." Li Chengqian agreed to Lao Fang's request with great considerateness, expressing his willingness to go to the old man's place with him to explain what happened to the evening.

Moreover, Li Chengqian really needs to explain to the old man what happened tonight. After all, this involves the old man from General Tiance's mansion. If he doesn't tell the old man, he is also afraid that he will lead to some bad ideas from Old Li.

Nowadays, no profession is easy to do, especially the high-risk profession of the prince, who must be extremely 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 here to do?" Li Er was ready to rest at this time. When he saw Li Chengqian coming, he asked in confusion.

What are you doing? Li Chengqian glanced at the old eunuch Fang and wanted to say: Your useless subordinate doesn’t understand the learning of the words, so I’m here to help him.

However, he swallowed it back when he said, clearing his throat and saying, "I have some grassland specialties here, so I'll use it for my father to taste it."

"Prairie specialty? Is it the thing in your arms?" Li Er asked, pointing at the can of milk powder held in Li Chengqian's arms.

"This is called milk powder, which is extracted from fresh milk from the grassland. Although the taste is not as good as fresh milk, it is rare to be a good product." Li Chengqian put the jar on the table aside and opened the lid to let the old man see it more clearly.

As the emperor, everyone was basically suffering from paranoia. Although Li Er was more courageous, he was no exception. So when he looked at the white powder in the jar, Lao Li also felt a little hesitant. The first thing he thought of was almost the same as Lao Cheng - arsenic!

Fortunately, Li Chengqian didn't want the old man to try the taste of this thing, because as the Emperor of the Tang Dynasty, Lao Li could drink it at any time even if he wanted to drink human milk. It was no problem with cow's milk and goat's milk. There was no need to drink milk powder.

So Li Chengqian just wanted to let the old man see what milk powder looks like. After seeing it, he covered the lid back and said, "Father, this milk powder lasts for a long time and can provide people with a lot of necessary nutrition, so my son believes that this thing can be used as a supplement to military rations."

"It's okay to be used as military ration, but the price..." Li Chengqian didn't need to say much about the benefits of dairy products. Li Er naturally knew, but he was still worried about the price.

According to Li Chengqian's personality of selling wine worth two cents of money for millions of cents of money, Lao Li believes that this milk powder will probably not be cheaper anywhere.

"Father, this milk and goat milk are very cheap. The price purchased by Datang is 2.5 kilograms, while a kilogram of milk powder requires about ten kilograms of fresh milk to be refined (according to modern technology, it is 8:1), so the cost price of milk powder is about ten kilograms."

"Ten cigarettes are not cheap anymore!" Li Er looked at the jar on the table, thought for a while and said, "Even if I am, I can eat two pounds of this thing. The soldiers below probably eat more..."

Li Er was talking with his fingers, feeling someone pulling his clothes beside him. When he looked back, it was Lao Fang. He couldn't help but glared at him impatiently, asking him to turn back if he had something to do.

Then he continued to say unhappy: "Let's just be a soldier who can eat three pounds in one meal, that's thirty folks. Chengqian, you think of me as a sucker, right?"

"Father, you misunderstood. This thing is not what you eat." Li Chengqian's handsome face turned red. After grunting for a long time, he suppressed the urge to laugh: "Father, this thing is consumed by water. If you drink a pound of milk powder for two meals a day and every time, you will probably be able to drink it for about half a month."

Drinking it? One pound is drunk for half a month? Li Er was stunned for a moment, and looked back at Lao Fang, who was standing with an innocent face, and didn't say a word for a long time.

This is too embarrassing. He even started to calculate the economic account without even knowing how to eat milk powder. Fortunately, there is no outside in the big tent now, otherwise he would be embarrassed.

Thinking of this, Li Er took a deep breath, slowly vomited it out, glaring at Li Chengqian viciously, gritted his teeth and said, "What else can I say it clearly at once!"

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

"That's all? That's all this night, so many of you are studying this broken thing?" Li Er pointed to the milk powder on the table and said angrily.

"No, that's not." Li Chengqian shook his head and pointed to the carpet in the old man's big tent and said, "I plan to export this to the Western Regions. Anyway, the Persian place is about to end. Only the Tang Dynasty will have such carpets in the future, and it can be sold at a good price in the Western Regions."

When Li Chengqian heard the word Western Regions again, Li Er fell into silence for a while, and then asked for a while: "Why are you investing so much power in the West? What do you want to get from the Western Regions?"

With his memory, Li Chengqian used a brush to outline the territory map of the Tang Dynasty on paper, and then drew a triangle on the west to represent the countries such as the Qin Dynasty, and then drew a duck egg on the lower left to represent Africa.

Then he pointed to the newly drawn position and said: "Father, the Western Regions are not the end, but a starting point. Only by firmly grasping the Western Regions in our hands can we have the ability to break out a wider space. The Qin Dynasty in the extreme west has Dashi, and even more land and resources are there to the west..."
