When Chu Bangqing woke up the next day, he was told that Otto and the others had set off to spread the news that the Misty Tribe was going to have a big commodity exchange in January.

"You don't want to discuss it with me again." Chu Wanqing rubbed his hazy sleepy eyes and looked at Xiu Lun, his voice with a hint of coquettishness.

"I can't bear to wake you up."

Chu Bangqing kicked Mio next to him.

It's all this tiger, and last night she had to pester her again and again, causing her to sleep long in the morning, and when she got up, she was on the clock.

"Qingqing~" Mio took the initiative to become a beast and rubbed the fur to the soles of Chu Bangqing's feet.

"Hmph." Chu Wanqing pedaled lightly again and puffed out his mouth.

"I'm going to teach them pinyin to Rogge today, and when the trading market is up, we won't be in a hurry." Xiu Lun glanced at the half-hung witch doctor next to him.

"I didn't say no, why are you looking at me?" Rogge touched his nose weakly, put the three cubs in his arms, Wang Chu Bangqing, and went out to continue building a house for the little snakes.

Although Phil seems to have no interest in Shichijo's sons, he takes them to the woods to teach them to hunt when he is idle.

Rogge was swearing while chopping wood, how could he have such a father and son.

After building a house for the father, he has to make it for the son.

Rogge's total, do you want seven little snakes to make seven wooden houses?

Forget it, their brothers have a good relationship, and let them live together for a few more days.

Snake: ??? We're not we don't!

For a few snake cubs in his own family, although they are not biological, they also have some feelings, especially Rogge has just become a father recently, and fatherly love is overflowing, and he wants to hurt any cub.

Rogge chose the hardest trees for the children, and made them the same warm device as Phil, which was convenient for hibernation in the future.

Chu Wanqing didn't catch up with Otto here, so he had to talk to Xiu Lun about the market.

"Our tribe has to be well prepared, especially salt, which is our best bargaining chip. As for bacon or something, those recipes are best given as benefits to those who have signed a long-term contract with us. ”

Mio knew that he was not qualified to speak on such a delicate matter with his own brain, so he obediently lay down beside Chu Bangqing as a pillow, and curled Chu Wanqing's calves with his tail from time to time.

"The amount of salt is no problem, we have established a base by the sea, which is according to the method of assembly operation you came up with, and now there are basically two large bags of salt a day, last time Mi Xiu told me that our tribe still has more than 300 bags of salt, and it must be enough to produce it for another month." Xiu Lun replied.

"There's another problem, we have to make a uniform weights and measures for salt."

"Weights and measures?" Xiu Lun heard another new word and raised his eyebrows.

"It's about using a uniform standard to measure, such as weight or volume, and it has to be very precise."

"It's simple, I'll dig a bowl, and I'll talk about the bowl later." Mio couldn't hold back and interjected.

Chu Wanqing tugged Mio's hair and said, "How many identical bowls can you dig up?" You can't just use one bowl for the whole world. ”

Hearing this, Xiu Lun touched his chin and frowned.

"We still have to measure by quality, we make a few things of the same quality......"

Before Chu Bangqing finished speaking, Mio snorted: "Qingqing still said about me, how can we make something as heavy?" ”

"Of course I can." Chu Wanqing twitched the corner of his mouth and patted Mio's head.

Quality can make simple balances.

But the volume is difficult, and the containers that can be made now are basically dug by hand, and it is really not easy to make a graduated cylinder.

Moreover, even if the excavated container is marked with a certain liquid, it is not accurate to measure it if it is not transparent.

"Qingqing murdered me." Mio deliberately stepped his head into Chu Wanqing's arms and rubbed it.

Then Xiu Lun has a problem.

How many steps are there to throw the tiger out?

Pick up the tiger, open the door, throw it out, and close the door.

"Qingqing, you go on."

Xiu Lun's movements were neat, and he didn't blush or beat his heart when he carried such a big tiger, and when he came back to ask, he acted like he was fine.

"Uh......" Chu Wanqing didn't have anything to knead in his hand, so he pulled his sons over, "I'll make an instrument that can measure things of equal quality, and set out the weights and measures." ”

"Okay," Xiu Lun nodded, "What materials do you need?" I'll find it for you. ”

"Just wood and sand. That's right...... Bring that tiger in too. ”

The balance is also a precision instrument, and no matter how simple it is, it cannot be simple in terms of technology.

"Okay."

Xiu Lun went out and took Mio back again, and then went to find what Chu Bangqing wanted.

"Qingqing~ Xiu Lun just now is so fierce." As soon as Mio entered the door, he pounced on Chu Wanqing's side and lied coquettishly.

Chu Bangqing: ......

After a while, Xiu Lun came back with a pile of sand and a large piece of wood from Rogge.

Chu Wanqing looked at it and felt that it was okay.

Now the only thing that can flexibly control the fine mass is sand, and the finer the sand, the more accurate it is.

According to Chu Bangqing's description, Mio made a balance, and naturally something was praised.

"Mio is the best." Chu Wanqing mechanically touched the dog's head.

Mio: Thank you for your busy schedule!

Chu Wanqing leveled the scales, and then poured sand on both sides.

She stopped when she estimated that she had reached ten grams, and continued to pour the other side.

"Mio, put it in that barrel and put it on ten."

Mio also learned numbers, and immediately happily found a tube to fill one side of the sand and carve a "10" on the outside with his fingernails.

Then Chu Bangqing divided the rest of the ones into two sides and made two "5s".

"Do we have to make it little by little, and then make 20, 50, 100, or even 110,000 like that? That's all for this set, and it's too cumbersome to make. ”

Xiu Lun couldn't help but feel a little distressed when he saw that Chu Bangqing was sweating fine from the sand.

"Not at all." Chu Wanqing was silent.

Although the balance is added or subtracted by various weights, and the range is not high.

But there is a thing called a scale, a weight is on the line, and I haven't seen anyone who sells vegetables and takes a box of weights, mainly to look at the scale, for a small transaction in Heisei, a scale can meet all your needs.

"But the first set still needs to be precise, and it won't have to be in the future."

Hearing Chu Bangqing say this, Xiu Lun relieved his heart, "I'll come, I know how to operate, you go and rest." ”

Xiu Lun took over, and couldn't bear to see Chu Bangqing tired.

"Okay, you come, just get a thousand, and then make a ten, two twenty-one fifty, a hundred and two hundred are also two, five hundred and one." Chu Wanqing didn't caress Xiu Lun's kindness and explained.

"Okay."
