"Ahem, ahem!" Li Dedao was choked by Robert's words, coughed for a while, and then relieved himself, nodded his head, and said with a suddenly realized expression: "Oh, I understand, what is this lady talking about?"

"Duchess of Smiki. Robert picked up the conversation and said.

Li Dedao clapped his hands, then pointed at Robert and said, "Yes, it's her!" and then said with a shy, "Anyway, she is 70 years old, can she stand playing such an exciting game?"

Robit smiled with a strange expression, "Duchess Smickey can't stand it, that's not something we should worry about." After saying that, Robert stood up, stretched his waist and said, "Okay, I've made it very clear, Baron Redsen, I'm just one high-grade black charcoal man, and I can make up enough 70, which is exactly the same as the number of the Duchess Smiki's 70th birthday." ”

"You have so many black charcoal people!" Li Dedao said in surprise.

"Almost all the high-grade Wutan people that the entire Kingdom of Gekia can collect are in my hands. ”

"Awesome!" Li Dedao said with a thumbs up.

"Baron Red Forest, there are still things to do in the future, we can't delay too long, I hope you can sell that black charcoal man to me soon. ”

After thinking about it, he stretched out his hand and said, "Hey, Mr. Robert, you wait a minute, let's put the matter of selling people first, I want to make friends with you, and I have a few questions I want to consult, do you think it's okay?"

"Oh!" Robert looked Li Dedao up and down, and said after a few seconds of silence: "The words of Baron Hongsen, who rescued the eldest princess, really make me feel honored, if Baron Hongsen has any questions, just open your mouth, as long as I know, I will answer you." ”

Li Dedao smiled and said: "That's a good feeling, it's like this, I don't know if it's convenient for you to say it, you can get from that one at a time...... That one....... ”

"Duchess of Smiki. Robert reluctantly said it again.

"Yes, this is the Duchess of Smicki, and how many tons of salt can you get from her at one time, Lord Robert. ”

Robert looked at Li Dedao with deep eyes and did not speak.

Li Dedao tilted his head and asked in a low voice, "Can't you say this?"

Robert shook his head and said: "What's so bad about this, there are so many outputs, everyone's quota is fixed, just ask around, the Gus Roland family can get 20,000 catties of high-grade salt from the Mivier Caesar family every six months." 100,000 catties of medium salt and 200,000 catties of inferior salt. ”

Li Dedao nodded and said: "Sounds like a lot, by the way, Your Excellency Robert, I don't know much about what you said about high-grade salt and low-grade salt, do you have a sample here?" I want to take a look." ”

"This ...... I do. Roberto nodded and said, then patted his palm three times, and a servant beside Robert immediately took three bags from his waist, arranged them in a row in front of Li Dedao's table, and opened them one by one and stepped aside.

Li Dedao curiously stretched his neck to look into the three bags, and in surprise picked up a lump of yellow clod-like things and asked, "This is also salt?"

"Yes, but it's a low-grade salt with a lot of impurities, and it's generally eaten by commoners and slaves. Robert explained.

"Oh! Li Dedao nodded in understanding, put down the inferior salt in his hand, reached out and grabbed a handful of salt the size of coarse sand in a bag and asked, "Is this high-grade salt?" ”

Robert said, "Yes, this salt is generally for the enjoyment of noble lords. ”

Li Dedao glanced at it when he heard this, threw the high-grade salt in his hand back into the bag, and was full of disdain for the salt of this other world, but he still dipped a little bit of his finger into his mouth and tasted it, and found that this high-grade salt not only had a faint salty taste, but also a bitter taste mixed in it.

"Phew!Bah!" Li Dedao spat a few times before he cleaned up the strange smell in his mouth, looked at Robert and asked, "Can you tell me the price of the salt you eat?" ”

Robert glanced at Li Dedao curiously, his brows furrowed slightly, and he thought about Li Dedao's intentions.

Li Dedao didn't urge, and picked up the barley wine on the table and drank it.

In the end, Robert sighed lightly and said truthfully: "When we bought it, the best salt was 20 copper coins for one tael, medium salt was 10 copper coins for one tael, and inferior salt was 5 copper coins for one tael. ”

Li Dedao used ten fingers together, tilted his head, looked at the top of his head, and began to calculate: "1 catty is equal to 10 taels, and high-grade edible salt is ...... 20 copper coins multiplied by 200,000 taels, plus 10 copper coins of medium salt multiplied by 1 million taels, plus 5 copper coins of inferior salt multiplied by 2 million taels, is equal to 24,000,000 copper coins converted into gold coins, which is 24,000. Multiply that by 2, which means that you will have to spend 48,000 gold coins every year. ”

Seeing the answer calculated by Li Dedao, Robert's expression was obviously shocked, and he stretched out his thumb and said: "It takes us several accounting offices to calculate this number for an hour to get the result, and it is really admirable that Baron Hongsen can calculate it so quickly." ”

"Hey! Li Dedao waved his hand and said nonchalantly: "After learning the ninety-nine multiplication table, everyone can calculate it so quickly." ”

"What is this ninety-nine multiplication table, it's so amazing. Robert was stunned and couldn't help blurting out.

"I'll tell you about this later, and I'll ask you how much you can profit from the middle. ”

Robert didn't think much and replied: "Aside from the expenses along the way, the net profit along the way can earn 30,000 gold coins a year." ”

"It's only 30,000! ”

Robert smiled self-deprecatingly: "Of course, in the eyes of a big man like Baron Redsen, it is not much, but more than half of the income of a small family like ours is maintained by this. ”

Li Dedao smiled and said: "I didn't mean to laugh at you, I want to ask you something, if there is a salt that is better than your high-grade salt, that is, the kind of salt that is as white as snow, as large as fine sand, and has a salty taste and no bitterness, will you want it?"

"Oh, and this salt?" said Robert, skeptically.

"Don't doubt it first, let me ask you, if there is this kind of salt, how much do you think you can sell it for a tael?"

Seeing that Li Dedao's expression didn't look like he was lying, Robert sat down, tapped the table with his hand, thought for a while, and said, "If there is really the kind of salt that Baron Hongsen said, I think it should be able to be sold for 50 copper coins to 70 copper coins for one tael." ”

"Then count him 50 copper coins. Li Dedao waved his hand and said, "You wait a minute, let me make a good calculation." ”

"Calculation!" Robert looked stunned for a moment, and then immediately asked in surprise: "So Baron Redsen can really get this kind of salt." ”

Li Dedao nodded and said, "Of course." Then he said to Barr, "Barr, get me some paper and pen." ”

"Yes, sir. Barr answered, and turned to the innkeeper to get a pen and paper.

Robert asked curiously, "What are you doing here?"

Li Dedao showed his hands to Robert and said, "Count, million-level numbers, if you count them, your fingers will not be enough." ”

"Hundred...... Million-level ...... level!" Robert was taken aback by Li Dedao's words again, and wondered in his heart what should be counted to the million-level?

After a while, Barr brought paper and pens, which were the finest paper of the Zhuqinermu family, and which were usually reserved for the nobles and magicians to communicate and record.

The pen is an ordinary quill pen, you can write with a little black ink, the first time you use a writing tool from another world, Li Dedao did not feel a trace of discomfort, picked up the quill and climbed on the desktop and began to write and draw.

Robert stretched his head over curiously, looked at the paper, and found that Li Dedao had written a bunch of words and symbols that he couldn't understand, so he asked with a bad face, "Hmm...... Baron Redsian you wrote ...... What is it?"

"Don't interrupt, I'll tell you later. Li Dedao waved his hand, didn't look at Robert said impatiently, and then muttered to himself: " My storage ring is a cubic meter, according to a cubic meter is equal to 1 million cubic centimeters, and a cubic centimeter is about equal to 2.1 grams of high-quality edible salt, that is to say, a cubic meter is equivalent to 2.1 million grams of high-quality edible salt, and a pound is equal to 500 grams, according to a cubic calculation, it is equivalent to 4200 kilograms of salt, I drop mom, this is true and false, I have always been bad at mathematics, I will not be wrong. Li Dedao scratched his head.

Driven by curiosity, Robert asked again, "Count...... What did you miscalculate?"

Li Dedao waved his hand and said, "I'll tell you later, I have to count it again." After speaking, he calculated according to the steps just now, and the final result was still 4,200 catties of salt.

Li Dedao touched his chin and thought about it, then continued to climb on the table and began to calculate: "This algorithm is indeed 4,200 catties...... I have 4 storage rings of 10 cubic meters, a storage ring of one cubic meter, if added together, you can hold 172,200 catties of salt, according to one or two salt 50 copper coins, I can get 86,100,000 copper coins, that is, 861,000,000 gold coins. ”

In the end, Li Dedao's whole person became excited, straightened up, kept rubbing his hands, and kept grinning: "Get rich! Get rich!"

Robert frowned, stretched his neck long, stared at the ghost-like numbers written on the paper by Li Dedao, and asked with doubts in his eyes: "Baron Hongsen, what are you writing here? ”

"Oh! It's called formula conversion, addition, subtraction, multiplication and division, and it's normal that you don't understand Arabic numerals. Li Dedao grinned and said, "It's okay if you don't understand, but you have to know that you are about to get rich." ”

"I'm going to get rich?" Robert was embarrassed by Li Dedao, and hurriedly asked, "What kind of fortune am I making?" Baron Redsen, can you make it clearer." ”

"That's ......" Li Dedao patted Robert's shoulder and just wanted to continue, but suddenly he was stunned, what's wrong? Am I mistaken, how can a storage space that is one meter wide and one meter long, and one meter high be able to hold more than 4,000 catties of salt, I feel wrong when I think about it with my ass, I must have miscalculated, yes, I must have miscalculated, thinking of this, Li Dedao's face began to feel melancholy.
