For a while, everyone's thoughts were immersed in Lu Yu's speculation.

Lu Yu smiled lightly, and then said, "By the way, you are called Shaoyi...... Do you have nine tails?"

Shao nodded and said, "Yes, there are nine of them." ”

"Wow, that's amazing, what's it? Can you show me?"

"Of course you can. ”

As she spoke, Shaoyi Fengyun's waist swayed slightly, and immediately nine tails burst out from under the skirt, fluffy, each very thick and soft, piled together, but bigger than her body.

Lu Yu's eyes lit up, so he hurriedly stepped forward, and then reached out very rudely to stroke the tail.

In fact...... No matter what kind of creature it is, they hate it when people touch their tails, such as cats or dogs, and even if they are their own pets, they won't be too happy to touch them.

So Shaoyi was stunned for a moment, and then his eyes were a little unkind, but then he saw Lu Yu looking very happy, and then saw a lot of delicious food on the plate, rolled his eyes, and dispelled the idea of beating him.

Lu Yu touched it happily, and then asked, "That...... Nine tails, that's already the most, why do you have to take a 'one less' name?"

Shaoyi rolled his eyes and said, "Because what I want is ten, and ten tails are good." ”

"Will there be ten tails?"

"This ...... I don't know, there are many tails in the legend, for example, in the record, there is an ancestor of the fox clan who has seventeen tails...... Well, it's really enviable. ”

"yes...... Envy, when you sleep, you don't need quilts and mattresses, these big tails are enough!"

Shaoyi was stunned for a moment, then couldn't help giggling, and said: "You guy is really strange, the tail represents the level of cultivation, but you only think about whether you are comfortable when you sleep, it's really strange." ”

This sentence made Xiao Ruan and the others behind Lu Yu feel weak for a while.

yes, this ...... It's really annoying!

And it's dangerous.

Lu Yu, this guy, although he seems to be a good person on the surface, ...... But most of the things he likes have been acquired by him, and now he likes this big fluffy tail, so ...... Are you going to get this fox spirit to bed too?

It's dangerous!

Even Xiao Ruan will feel very dangerous.

So they were all vigilant and watched the vixen...... No, it's a little bad to look at Shaoyi's eyes.

Lu Yu smiled, and then said, "Oh, it turns out that there are so many tails, so why did you only say one less, but not less...... A dozen?"

"Well, of course, I'm satisfied with ten, I always feel that ten is the most number, and I don't know why. ”

"Yes...... Limits?"

"Limit?"

"Yes. Lu Yu said with a smile: "Actually, most of the races, no, the vast majority of the races, except for those who conform to the way of heaven and comprehend all things in the world with the roots of the universe, are actually ten ...... It's all the ultimate surface. ”

"Oh, in line with heaven? What kind of count is that?"

Lu Yu said with a smile: "Sixteen, taking sixteen as a cycle is the supreme principle of the universe, and there are too many ...... Well, there really are so many things that need to be explained to you to understand. There is also a kind of twelve, with twelve as a cycle, that is, to see the heavens and the earth, there are four seasons of change, yin and yang, in order to have this understanding, of course, the heavenly realm we live in is not these, so originally I thought that the heavenly realm is to the number sixteen as the extreme, so I guessed that you have fifteen tails, but now I want to ...... In the current Heavenly Realm, there are really no people who have cultivated so high. ”

"That's a novelty. ”

Shaoyi smiled lightly, and then said, "Sixteen...... I haven't heard of this too much, but maybe the number sixteen is really the limit of a world, because it is recorded that the predecessor with seventeen tails has already broken through the shackles of the world, and I heard that he has gone to other places, but I think it may be because the cultivation is too high, so he died, hmm...... It's really possible. ”

Lu Yu smiled: "So...... You're all ten......? It's a bit low-level. ”

"Why?"

Shaoyi was a little unhappy, for the term low-level, after all, in the entire heavenly realm, everyone's perception of divine beasts seems to be always related to the word 'low-level'.

Lu Yu smiled: "Naturally, it's because of ...... You see, those with the sixteen limits are those who have insight into the world, and those with the twelve limits are those who understand nature. But with ten as the limit? hehe, actually...... This is the most primitive way of counting, because Na ...... We have this counting tool on us. ”

"We ...... Have a counting tool?"

"Yes," Lu Yu directly stretched out his hands, and then said with a smile: "You see, you still remember that when we were very young, we didn't know much about language, but when we want to calculate some numbers, such as how many fruits and how many pieces of meat are in front of us, what method do we use to calculate them?"

Shaoyi said: "That's naturally fiddling with your fingers, one is a number." ”

"Exactly. ”

Lu Yu smiled: "That's right, one is a number, but we only need to count to ten...... We don't have enough fingers, what if we don't have enough? Draw a stripe on the ground, record that it's one, and then continue fiddling with our fingers from the beginning, right?"

"Hmm...... That's exactly what it is. ”

Lu Yu smiled: "So...... Our method of counting comes from our own fingers, counting with our fingers...... Doesn't that mean we're extremely inferior? So it's not like my family, who have always counted at the limit of sixteen, and are obviously much more advanced than you. ”

"You ......"

"Hehe, I seem to be talking too much. ”

Lu Yu looked at Shaoyi's deflated appearance, and couldn't help but laugh directly.

The one less glared at him directly.

Merely...... Neither of them actually told the truth.

The so-called decimal system is not fucking natural at all.

But...... This decimal system was spread all over the world, or at the time of its origin, it was actually the same as the decimal system, and it was all fiddling with the fingers.

Merely...... The guy who once invented mathematics and was the first to use this systematic way to count, that is, the Yellow Emperor, is ...... Six fingers.

The fingers are six.

The toes are also six.

So with the hexadecimal notation, it's as simple as that.

What is a day divided into 12 hours, what is a year that has 12 months...... In fact, it is all based on this method, and not anything natural, after all...... If it's really in line with the nature of the earth...... There are 365 days in a year, which does not translate into exactly 12 months, and the number of days in the months is different, and even the reason for its formation is like a joke.

And the one less lied too.

She wasn't called one less because she wanted ten tails.

From the time she only had one tail, she was called one less, and when she got to five or six, she was still called one less, because in her cognition, her tail was forever missing!
