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

"what?"

"Ding, surprise from Liu Changwei, the naughty value is 78!"

Liu Changwei was completely frightened.

He immediately knelt down on the ground and said: "Eighth prince, the old minister dare not resell the grain sent by the emperor. These grains are used to help the common people, and the old minister dare not touch them!"

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

Li Chengfeng frowned, and said: "City Master Liu, you didn't say that we should resell the food from the treasury, what I mean is! Let's go to Turkic and Tubo, buy food at double or even triple the price, and then wait until they are hungry and have nothing to eat At the moment, we are selling it at six or seven times, or even ten times the price, and continue to sell it to them, so that we can make a fortune?"

"Shh...so that's the case?"

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

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

But when Li Chengfeng finished explaining, Liu Changwei understood Li Chengfeng's purpose, and he was relieved.

Liu Changwei said: "Eighth prince, your idea is very good! However, I don't have that much money, so I can buy out the grain of Turks and the cities around Tubo!"

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

"Okay, I can answer that!"

Liu Changwei nodded. He lived in Suzhou City all year round, so how could he not know the situation of the surrounding Turks and Tubo?

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

Liu Changwei said: "The two cities of Tubo and the three cities of Turkic are on the border of our Tang Dynasty! Calculated according to the population of 100,000 in each city, their total population is about 500,000, and their combined strength is about 100,000 About 10,000 catties! Their military food over the years has been replenished from the city, and there are about 5 million catties of food, which are provided to their army for logistics."

Liu Changwei carefully analyzed the military strength, population, food and grass in the surrounding cities of Turks and Tubo, and Li Chengfeng was also listening carefully.

Immediately afterwards, Li Chengfeng asked: "Then City Lord Liu, what are the prices of grain and grass in the surrounding countries?"

"Well, let me think about it! One gold is equal to ten silver, one silver is equal to ten pennies, and one penny is equal to ten copper plates!"

"Based on the previous grain prices, you can buy a catty of rice for a penny. Due to the drought this year, the price of grain will almost triple. That is, you can buy a catty of rice for three pennies!"

After Liu Changwei finished speaking, Li Chengfeng nodded and said, "Okay, this information is enough. Wait a moment, and I will calculate how much money it will cost to buy up all the food in the five cities of the two countries!"

"Okay, Eighth Prince, I'll get you the abacus!" Liu Changwei said with a hearty smile.

But Li Chengfeng waved his hand and said, "You don't need the abacus, I can do it in my head, it's fast!"

"Ah? This... is also good!"

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

Now, the price of grain in the surrounding area is around 30 yuan, about a catty of rice.

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

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

2250 divided by 3 equals 750.

In other words, the money I brought is enough to buy their 7.5 million catties of grain.

Li Chengfeng leaned on the table thinking, Changsun Wuyi and Liu Changwei both looked at Li Chengfeng curiously.

They thought, how could such a complicated calculation be done directly in their minds?

Moreover, the conversion of various units, addition, subtraction, multiplication and division are 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 it is calculated on the basis of three jin of rice, we can buy them 7.5 million jin." food!"

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

Li Chengfeng's sudden words stunned Liu Changwei.

I saw Liu Changwei blinked his eyes in a daze, and said: "Eighth Prince, you are so fast, it's over?"

"Yeah, I'm done! Any questions?"

"No, no problem. The Eighth Prince is really the number one genius child prodigy in the Tang Dynasty. In the past, the veteran only heard about it in legends. Now, seeing the Eighth Prince's intelligence, I really shocked the old minister. It's not as good as being famous!"

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

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

And, he hasn't used the abacus yet.

"Okay, I've already finished the calculations! City Lord Liu, the prince now has 225,000 gold in his hands. I need your manpower to help me buy food from the Tubo and Turkic border areas!"

"225,000 gold? The Eighth Prince ~lightnovelpub.net~ Is all this money yours?"

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

Li Chengfeng nodded and said, "Yes, that's right, it's all my money! And that doesn't count the two iron mines I own! Those are my real assets, and this is my mobile money!"

"City Master Liu, I will pay for the money, and you will pay for the manpower. I will give you a commission of 10,000 gold for the money we earn, how about it?"

"What? A commission of ten thousand gold?"

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

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

As the city lord of Suzhou, his monthly salary is only a few tens of dollars. If he wants to earn 10,000 gold, it will take at least 100 years.

If he relied on salary alone, he would not earn ten thousand gold in his life.

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

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

"This is a good deal! But, Eighth Prince, you bought so much grain, do you plan to transport it back to Chang'an City?"

"You don't need to worry about City Lord Liu! This prince naturally has his schemes. You just need to do things according to my orders, no problem?"

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

Liu Changwei thought for a long time, finally gritted his teeth, and said: "Okay, then the city lord will personally take people to the Tubo and Turkic cities to buy food. At that time, the Eighth Prince will definitely be satisfied!"
