Li Chengfeng smiled lightly and said: "Resell grain, buy it at a high price, and sell it at a higher price!" ”

"Huh?"

"Ding, surprise from Liu Changwei, naughty value +78!"

Liu Changwei's whole person was scared silly.

He knelt on the ground and said, "Eighth prince, the old minister doesn't dare to resell the grain sent by the emperor, these grains are used to relieve the people, and the old minister doesn't dare to move!" ”

Liu Changwei thought that Li Chengfeng was going to resell the grain in the treasury.

Li Chengfeng frowned and said, "City Lord Liu, you didn't say that we should resell the grain in the treasury, I mean!" Why don't we go to the Turks and Tibet, buy grain at two or even three times the price, and then when they are hungry and have nothing to eat, we will sell it at six or seven times, or even ten times the price, and continue to sell to them, so that we can make a fortune? ”

"Shh......h So that's the case? ”

Liu Changwei wiped the sweat from his forehead, he was really frightened by Li Chengfeng's words just now.

He also thought that Li Chengfeng was going to sell millions of catties of grain in the granary of the country to the people of Suzhou City.

However, when Li Chengfeng finished explaining, Liu Changwei understood what Li Chengfeng was for, and he was also relieved in his heart.

Liu Changwei said: "Eighth Prince, your idea is very good!" However, I don't have that much money to buy out the grain of the cities around the Turks and Tibet! ”

Li Chengfeng waved his hand and said, "It's okay, just tell me how many cities and how many people there are around Turkic and Tibetan!" ”

"Okay, I can answer that!"

Liu Changwei nodded, he lived in Suzhou City all the year round, how could he not know the situation in the surrounding Turks and Tibet?

Moreover, as the lord of a city, it is common for him to understand the dynamics of the population of the enemy country next door.

Liu Changwei said: "The two cities of Tubo and the three cities of Turkic are leaning on the frontier area of our Tang Dynasty!" According to the calculation of the population of 100,000 in each city, their total population is about 500,000, and the approximate overall strength is also about 100,000! Over the years, their army food has been supplied from the city, about 5 million catties of food, which is provided to their army for logistics. ”

Liu Changwei carefully analyzed the troops, population, grain and grass of the cities around Turkic and Tibetan, and Li Chengfeng was also listening carefully.

Immediately afterwards, Li Chengfeng asked: "Then City Lord Liu, what is the current price of grain and grass in the surrounding two countries?" ”

"Well, I think about it! One gold is equal to ten silver, one silver is equal to ten hanging coins, and one hanging money is equal to ten copper plates! ”

"According to the previous grain prices, you can buy a pound of rice with a penny, because this year is a drought, so the price of grain will almost increase by about three times, that is, three pennies, buy a catty of rice!"

After Liu Changwei finished speaking, Li Chengfeng nodded and said: "Okay, this information is enough, you wait a while, I will calculate how much money will be needed if you want to buy up the grain in the five cities of the two countries!" ”

"Okay, the Eighth Prince, I'll get you an abacus!" Liu Changwei smiled heartily.

But Li Chengfeng waved his hand and said, "No need to calculate, I do mental arithmetic, it's fast!" ”

"Huh? This...... It's good!"

Li Chengfeng doesn't know how to make a disk, but as a mathematical genius, his mental arithmetic speed is much faster than using an abacus.

At present, the price of grain in the surrounding area is about 3 yuan, about a pound of rice.

And I, Li Chengfeng, have 225,000 gold in my hands.

Converted into 2.25 million silver, it is equal to 22.5 million hanging money.

2250 divided by 3 equals 750.

In other words, the money I brought was enough to buy 7.5 million catties of grain for them.

Li Chengfeng leaned on the table and pondered, and the eldest grandson Wuyi and Liu Changwei both looked at Li Chengfeng curiously.

They think, how can such a complex arithmetic be directly calculated by heart?

And the conversion of various units, addition, subtraction, multiplication and division, is very complicated.

Suddenly, Li Chengfeng snapped his fingers and said, "It's done!" City Lord Liu, this time the prince brought a total of 225,000 gold, if we calculate according to three hangs and one pound of rice, we can buy 7.5 million catties of grain from them! ”

"So, should we start with the Turks or the Tibetans first?"

Li Chengfeng's sudden words directly made Liu Changwei confused.

I saw Liu Changwei blink his eyes in confusion and said, "Eighth Prince, you are so fast, it's over?" ”

"yes, I'm done! Is there a problem? ”

"No, no problem. The Eighth Prince is really a prodigy on the first day of the Tang Dynasty, in the past, the old minister only heard it in the legend, but now when he sees it, the intelligence of the Eighth Prince is really shocking to the old minister, and it is not as famous as far and near! ”

Liu Changwei has never seen a person with such a fast mental arithmetic speed.

In less than a minute, Li Chengfeng solved such a complex arithmetic problem?

And he didn't use an abacus yet.

"Alright, I've done the math! City Lord Liu, this prince now has 225,000 gold in his hands, and I need your manpower to help me buy grain from the Tibetan and Turkic frontiers! ”

"225,000 gold? Eighth Prince, is all this money yours? ”

Liu Changwei looked at Li Chengfeng in shock, with a hint of envy in his eyes.

Li Chengfeng nodded and said, "Yes, that's right, it's all my money!" And that's not even counting the two iron mines I own! That's my immovable asset, it's my mobile money! ”

"City Lord Liu, I will pay for it, you will contribute manpower, and when the time comes, I will give you a commission of 10,000 gold, how about it?"

"What? A commission of 10,000 gold? ”

"Ding, surprise from Liu Changwei, naughty value +99!"

As the lord of a city, Liu Changwei naturally knows what the concept of 10,000 gold is.

As the lord of Suzhou, his monthly income is only a few dozen dollars, and if he wants to earn 10,000 gold, it will take at least more than 100 years.

If he relied on Yu Lu alone, he would not be able to earn 10,000 gold in his life.

After thinking about it carefully, Liu Changwei asked again: "Eighth Prince, are you serious, are you willing to give the old minister a commission of 10,000 gold?" ”

Li Chengfeng nodded and said firmly: "That's right, as long as you follow my instructions, help me do things, and buy all the grain in the five cities around Turkic and Tubo, I will give you 10,000 commissions, how about it?" ”

"It's a good deal! However, the Eighth Prince, you have purchased so much grain, do you plan to transport it back to Chang'an City? ”

"Don't worry about this City Lord Liu! This prince naturally has the plans of this prince. You just have to do what I tell you to do, no problem, right? ”

Li Chengfeng was still waiting for Liu Changwei's answer.

Liu Changwei thought for a long time, and finally gritted his teeth and said: "Okay, then the city lord will personally lead people to Tubo and Turkic cities to buy grain, and when the time comes, it will definitely satisfy the Eighth Prince!" ”
