"Follow me in the future, I will provide as many magic crystals as you want, you just need to rest assured that you can do experiments boldly, and you will have a salary of 1 golden bear every month. Pen? Interesting? Pavilion wWw. ｂiquge。 infoYour family will live in Sunset and live with you. ”

These are the words that Van Pei said when he asked Nina to leave the room.

Nina didn't understand why the great nobleman didn't burn herself, and allowed herself to do the experiment.

Maybe it's the bad taste of the great nobles, right?

I heard that many nobles in the royal capital have privately kept some alchemists.

However, after seeing that her family was safe and sound, especially after discovering that she owned an alchemy room, Nina really doubted her judgment. And as long as he asks for magic crystals and some tools, there will be soldiers who will immediately send them to him, no matter how much he asks, he should be satisfied.

My three meals a day consist of white bread and beef, as well as some vegetables and fruits.

Even when he walked out of the alchemy room and wandered the streets, no one guarded him, he was completely free. Nina had no doubt that if she sneaked out of Sunset Town, she wouldn't be discovered.

But Nina didn't dare to leave, there was good food and drink here, and there was family to accompany her, and this big nobleman didn't seem to like to abuse herself.

And once they leave, they are likely to be arrested again and sent to the Holy See to be burned in public.

And Nina also inquired that this was Sunset Town, which was not destroyed by the Holy See and the Kingdom Knights in order to exterminate the alchemists, as she thought, but was burned by the Xuedi rebels in the north.

"Otherwise, let's live, it doesn't seem like a bad thing."

Nina, who had lived in a dark underground prison for half a month, breathed a long sigh of relief.

Nina looked around and noticed that the town was strange. The knights, who are high up, are actually repairing houses for the untouchables with the militia. Not to mention the Kingdom of Bears, even a business alliance can't have such a thing.

But, it doesn't seem bad.

Nina thinks she loves it here.

……

The Knight of Carmen and the hundred militiamen of Vickdun were sold to Van Pei by Baron Hill, and naturally their families were also sent over. With the addition of these new forces, Sunset Town has been cleaned up much faster than before.

The population of Sunset Town had now recovered to nearly four hundred, and with the serfs of Baron Zoon's family, which had been sent one after another, the population had quickly recovered to nearly seven hundred, although it was still a far cry from the original three thousand or so inhabitants.

In addition to cleaning the streets, Van Pei also had Carmen and his people merge several houses to make them look like factories, and in a few days a large number of spinning machines will be delivered, and Van Pei will transform them into Jenny spinning machines, which can provide hundreds of jobs.

But now, Van Pei is in Nina's alchemy room and is witnessing the first invention that Nina has spent a lot of time researching, the mechanical calculator.

For this invention, Van Pei was very pleased, as long as those stupid old and rough soldiers used this kind of mechanical calculator to operate, at least the probability of wrong accounts would be much lower.

Nina's mechanical calculator is a rectangular box that requires a key to wind up and a series of gears inside that are turned by a handclot. Except for a few gears that don't need precision, the rest of the precision gears are all handmade by Nina in the past few days. Standardized special abilities allow Nina's gears to be formed at one time without the gears getting stuck.

However, the Grizzly Kingdom's complex numbers are difficult to identify, such as Van Pei's use of 1 for one, 10 for ten, and 100 for one hundred. The first 1 is the same, and the second is just 0. And in the Grizzly Kingdom, one is an I, ten is a V, one hundred is XL, and one thousand is an MC.

For example, one thousand one hundred and eleven, Arabia is 1111, and the grizzly kingdom is MCXLVI. More than 1,000 digits are more troublesome, 10,000 is MCX, and 100,000 is MCXX.

111111, the Grizzly Kingdom wants to use MCXXMCXMCXLVI.

So if you use MCXXMCXMCXLVI and add MCXLVI, this calculation will be troublesome.

And because there is no decimal system, the calculation is through cumulative superposition, such as 5X15, Van Pei quickly calculated 75 under the decimal system of the ninety-nine table, but the grizzly kingdom knows that it is 5 15, which is equal to 2 15+15 and 1 15.

The steps of the calculation are:

Step 1: 15+15=30.

Step 2: 30 + 30 = 60.

Step 3: 60 + 15 = 75.

This is still a small number multiplication, if it is a large number multiplication, it can count people to death, even if you look for one or two thousand items in the algorithm table, you can be dazzled by these letters.

So the ideal is very beautiful, and the reality is very skinny.

Nina's research on the mechanical calculator, from nine to ten, ran into more and more trouble.

Unlike the ten numbers 0-9 that can represent all the results of hundreds, tens of thousands, and hundreds of millions, Nina's calculator must not only have 0-9, but also tens, hundreds, thousands, and tens of thousands...... All the way down to an endless number of individual numbers.

In short, Van Pei felt that he would be dazzled and particularly brain-screwing.

"These are the Arabic numerals corresponding to the numbers of our kingdom, and I have written out the rules for the arrangement of the numbers, and after you remember them, this mechanical calculator only needs these ten numbers. In addition, this is the ninety-nine multiplication table, and the decimal system I said, you can basically calculate a lot of data after you memorize it. ”

Van Pei threw the manuscript paper he had written before to Nina, although Nina was not an internal affairs talent, but when it came to learning these things, she was undoubtedly much faster.

Looking at the few pieces of paper thrown over by Van Pei, Nina was completely confused, she was already using the more advanced calculation method of the Western Business Alliance, is there a more advanced calculation method?

"Look how I'll laugh at you later."

With this attitude of wanting to laugh, I glanced at the rules of the so-called Arabic numerals.

The more she looked, the more surprised she became, especially the explanation of the ninety-nine multiplication table and the decimal system, which was many times better than her stupid calculation method, and Nina felt that she had opened up a whole new world, and these few pieces of paper were enough to change the arrival of a world.

"This, is this really for me?" Nina clenched the paper tightly in her small hands, for fear of being snatched away by Van Pei.

"Learn today, and tomorrow I'll see a brand new calculator."

Van Pei yawned and left the factory, having not slept well at all in the past few days. Van Pei is now counting on Nina to quickly improve the calculator and then popularize this simple and easy-to-use mathematics, so as not to exhaust herself to death.

Before coming to the alchemy room, Van Pei had already issued more than thirty wrong accounts to be corrected.

Nina, who has found the treasure, spends an afternoon studying these pieces of paper in the factory, and then changes her mind to improve the mechanical calculator. Until late at night, he braved the heavy snow to knock on the door of Fanpei's room and directly pulled Fanpei out of the bed.

This was the first time Van Pei had slept in bed in the past few days, and he was woken up.

"Teacher, you see I replaced these numbers with Arabic numerals, and there are only these ten numbers, but if 4+6=10, I can't get into ten digits to show the result."

Nina has unconsciously changed her name to call Van Pei a teacher, and Van Pei is sleepy at the moment.

"Every decimal carry system, you can make a ratchet device with a small claw, when the positioning gear 9 turns, this pawl will gradually rise, and when it reaches 0, the pawl will fall, pushing the ten-digit gear forward one gear. Okay, you figure it out for yourself, I'm going to sleep. ”

These simple mechanical principles, Van Pei dismantled the mechanical clock when he was a child, not to mention this kind of originally very simple principle.

But this is an unprecedented new experience for Nina, the problem of the carry system has been bothering her for a long time, she tried many methods but could not solve it, but she didn't expect to be hurt all of a sudden.

Are the nobles of the royal capital so knowledgeable?

For the first time, Nina was a little skeptical of her common sense, in her common sense, the Grizzly Kingdom is very old-fashioned, how could such a freak appear?

But now, with black panda eyes, this freak directly pushed the petite Nina outside the snowy house and slammed the door shut.

"Don't wake me up again, or I'll send you back to the Fury Wind Fortress."

"Oooh......"

Outside, Nina shrank her head in silence, put down the hand that was about to raise and knock on the door, and ran back to her alchemist to start making the little paw ratchet device that Van Pei had said.
