"Forty-seven kilograms? What is it? Yin Tingyan was a little puzzled.

Looking at him with a bewildered face, Xia Ling thought that the Great Xia Dynasty was the second generation of emperors when he came to Yin Tingyan.

Not to mention weights and measures, there is not even a unified language here, a county town and a village here, separated by three or four miles, but they are not in the same language.

Xia Ling: "Forget it, you don't understand it, a kilogram is a kilogram, which is what we use to weigh the weight of Miao Gu in the southwest, which is the same as the city, jin, and two in Great Xia." ”

"Is it weighing?" Yin Tingyan thought thoughtfully, "Why don't you talk about it?" ”

Unifying weights and measures is something that every emperor would do in the early days of the empire, but now, Yin Tingyan has not yet met that beauty, and of course he cannot get the wisdom from the 'modern'.

"Okay, come to bed, I'll tell you~" Xia Ling smiled.

Yin Tingyan: "......"

He ended up going with her.

The two of them were coiled on the bed, Xia Ling found the palace maid and asked the palace maid to take two eggs from the imperial dining room.

The jade plate is filled with two raw eggs, which makes the eggs look very cute.

And picking up the egg and checking it in his hand, Xia Ling asked Yin Tingyan: "Do you know what this is?" ”

Yin Tingyan looked at her, and then at the plate, "Eggs?" ”

"It's an egg, yes! But do you think it's just ordinary eggs? Smiling lightly, Xia Ling looked mysterious, put the two eggs in one hand, and checked them.

Then, she pulled Yin Tingyan's hand and put two eggs in his palm.

Xia Ling: "Do you feel it?" ”

Look at Xia Ling, Yin Tingyan learned what she did just now, and swept the egg in her hand?

Xia Ling: "Do you feel the weight?" ”

"Oh-" I felt the weight!

Yin Tingyan regained his indifference: "I feel it!" Two eggs, not too heavy, probably ...... Have one or two! ”

It's all figured out!

Xia Ling glanced at him in admiration, and then concluded: "According to the weighing method of our Miao Gu family, these two eggs are one cow, and one cow is one kilogram, do you understand?" This tael is equal to one kilogram of ours! ”

Yin Tingyan: "...... A cow? ”

"Not the cow you think!" Xia Ling had a black line, and he didn't know how to explain it at the moment.

There is no Newton in this world, and there are no laws of physics, if she wants to explain this problem to Yin Tingyan, does she have to start with Newton being hit by an apple under a tree?

Xia Ling: "Okay, the cow just now is not a cow, you should not have heard of it." But I later said, two eggs, equal to one kilogram, and one kilogram equal to one tael, do you understand? ”

"Understood." Yin Tingyan nodded, his slender hand playing with the two eggs, and he was thoughtful.

Xia Ling has never been a teacher, and he doesn't know what he just explained, what Yin Tingyan understands.

But he finally got it!

"It's good to understand, Your Majesty, feel free to do so, I'm going to sleep." Xia Ling motioned for Yin Tingyan to go.

She is used to Yin Tingyan's 'ruthless' style, she is used to sleeping alone, if Yin Tingyan wants to stay at night, Xia Ling is afraid that she is still a little unaccustomed.

But people are like this, when they are leaving, they feel that they have the upper hand.

was driven out, and Yin Tingyan felt unhappy.

He looked at Xia Ling lightly, and as soon as he lifted his dark robe, he sat on the bed and began to unbutton it.
