Yes, since Song Yu officially became the chairman of Boulder City, no one has called her a fluke except for her family and the elders who are close to her clan.

At this moment, I saw that she was sent back by the tree god, and at the same time sent a few bags that were so magical.

The clansmen were curious, wanting to see if the tree god or the god of song had something new for Song Yu to bring back.

Of course, Song Yu is happy to see this.

After all, if you want to earn more trading points, you have to consume the goods you trade back as soon as possible.

Only in this way can you maximize the benefits of trading.

"Master, are you back?"

As soon as Song Yu was sent back to his yard by Changqing, Xiong Lan, who was drying herbs, greeted her, "What is this?" ”

"This is very delicious food, I will make it for you to taste for the teacher today."

Seeing the eldest disciple ushering, Song Yu smiled happily, "Come, Lan Lan, help the master move one of the bags to the kitchen." ”

"What about the rest?"

Xiong Lan bent down to carry one of the bags, but she didn't forget that there were seven more bags here.

"For the rest, let each family exchange their things."

Song Yu's tone was relaxed, "For example, animal skins, animal bones, animal meat, and all kinds of rare plants in the jungle can be exchanged." ”

Xiong Lan looked at the only seven bags of wheat flour in the courtyard, and couldn't help asking, "Master, can my family come and exchange this thing?" ”

"Of course."

Song Yu agreed very happily, "Exchange conditions, I'll write them out later, and you can help exchange them for the teacher." ”

"Well, don't worry, master, the disciple will exchange with people in strict accordance with your regulations."

Xiong Lan listened to Song Yu's words, and agreed with joy, "Master, you go and set the rules first, and the disciple will move this into the kitchen first." ”

"Okay, before exchanging, keep what your family needs, don't change until the end of the house is gone."

Song Yu reminded, "The rest ask your junior brothers and sisters if they need it, after all, it is our own things, of course, we will come by ourselves first." ”

"Don't worry, master, the apprentice understands."

Song Yu nodded with satisfaction, turned around and went into his room, found a piece of fabric, went to the kitchen to pick up an unburned branch, and began to write.

Recently, Song Yu pretended to teach He Yu to read and write, and then asked He Yu to teach Xiong Lan and Weifeng.

The two discussed, although the ancient civilization could not be broken, they were only members of the general public in their respective eras.

It is impossible to replicate the inheritance of the earth's civilization.

What the two of them can do now is to pass on to their people what they have learned from each other and what they can use in this era.

For example, words, such as arithmetic, and then for example, the calendar solar terms and some agriculture-related seasons.

Song Yu and He Yu discussed in private, but there was no record of the years, months and days, and they always felt that something important was missing in their lives.

Therefore, the two decided to start recording the next snow season, and set the date of the next year's snow stop as the first month of the first year of the wilderness.

Of course, before this, Song Yu told He Yu to realize the rotation of Jiazi according to climate change and changes in the starry sky.

Because of this, the Song family, Xiong Lan, Wei Feng and others have already learned some words.

What's even more interesting is that He Yu also got a wooden scale out.

In this regard, Song Yu was really convinced of this little disciple.

Since then, everyone has exchanged goods, except for things that are convenient to be in units, and the rest are called catties, taels, and units.

Song Yu took a charcoal pen and brushed a full page of words on the white cloth:

Wheat flour and various objects exchange conditions:

The god of song provides wheat flour for the people of the Giant Rock to improve their lives......
