It seems that the weather is already in autumn, and it should be about the eighth and nineth months of the Gregorian calendar or the seventh month of the lunar calendar.

However, there was no calendar in this primitive tribal era, so there was no accurate year, month and day to record the time.

But primitive people can also roughly divide the months through changes in the moon phase, and divide the seasons and years through changes in plants.

However, neither the season nor the month has established any accurate relationship.

It takes one day to alternate day and night.

The moon is full and waning once, and it is one month.

The plants and trees wither and flourish for a year.

Spring flowers are blooming in autumn, summers are hot in summer, winters are cold in winter. This is the change of the four seasons.

All of these concepts of time remain in the most primitive and ignorant feeling.

Therefore, it is impossible to calculate the exact time of occurrence of each thing.

The simplest is like age, no one can know exactly how old they are.

At most, after everyone is born, the mother will carve a mark on the stone wall every year, and for every one more person, Mother Ba will carve a mark on her own special staff. However, the tribe members have life and death. Her staff is already full of marks. Not to mention that others cannot understand it, Xu Chen dares to believe that Mother Ba is already confused and can only rely on guessing.

Xu Chen even suspected that Mother Ba would not count.

Because the entire tribe doesn't know how to count, they usually sway fingers and pile up small stones. They judge the amount of things in the pile, and adults can usually count to ten, because there are only ten fingers, and the larger number is beyond the range of organs they can learn from.

Of course, the middle of a man does not count, it is a semi-hidden number, and its state is not very fixed, and it is in an uncertain quantum state between one and non-one.

If you don’t know how to count, you naturally don’t know how many days a year, one month or more.

Recently, Ye has learned to use larger numbers and can also add and subtract single-digit numbers, so he is very interested in the number fifteen that suddenly appeared in Xu Chen. Xu Chen also decided to use the moon to teach her a simple calendar.

The calendar established by the phase changes of the moon is called the lunar calendar. The lunar calendar is an inaccurate chronological method, and the year, month, season and time are not fixed, which is not suitable for guiding agricultural production. However, for this primitive man who has no knowledge of astronomical knowledge, it is the simplest and easiest solution to identify and accept.

Actually, Xu Chen doesn’t care whether the year, month and day are correct. The main reason is that he needs to have such a calendar to record the time. Otherwise, as the time travels through time, he will gradually not even know how old he is, which is tragic.

With the faint moonlight, he first drew a circular moon phase change diagram on the stone wall, from zero to six o'clock clockwise, which was the upper chord and the lower chord and the lower chord and the lower chord and the lower chord and the lower chord and the state of the moon is in no state.

"Understand?" Xu Chen turned around and asked after painting.

Ye looked at it carefully for a long time and shook his head.

Xu Chen had no choice but to point to the full moon state at six o'clock in the moon phase, and then point to the full moon in the sky.

Ye instantly understood and nodded vigorously.

"fifteen!"

Xu Chen smiled and wrote two numerical symbols ix at the full moon at six o'clock, then moved his hand back counterclockwise to the upper monsoon chart at three o'clock, wrote two numerical symbols 7 and 8, and then pointed to the direction of nine o'clock, wrote two numerical numbers 22 and 23, and finally wrote thirty at the blank zero o'clock.

After writing, he used his hands to draw a circle around the whole moon phase and said, "One month, understand?"

Ye shook his head blankly.

Xu Chen:...

It's too difficult for me to understand such a simple picture.

Xu Chen had the urge to die.

But when I think about it, I feel calm and I am facing a primitive man who is still eating raw meat, drinking blood and wearing fur, which is like teaching astrophysics to kindergarten friends.

Although Ye is over teenage, he has just learned how to add and subtract single-digit numbers and can barely count numbers within thirty.

So he could only patiently continue to explain the relationship between the moon phase and time slowly.

Fortunately, Ye was able to accurately understand the numbers and clearly understand the changes of the moon. After explanation, although he was confused, he also understood a little.

Time is like water, and the night is getting darker.

It is estimated that it will be nine o'clock in the evening.

Ye yawned.

It is obvious that learning makes people sleepy, especially courses that cannot be understood.

Seeing Ye Rushing his eyes and looking drowsy, Xu Chen had to throw down the charcoal sticks and said, "Sleep!"

"Oh!" Ye Mimi went into the cave in a daze.

Xu Chen looked helpless, then looked up at the deep night sky and a bright moon alone and continued to stare blankly.

Although it has been traveling for more than a month, it is still incompatible with this era.

I don't know what the meaning of doing this is.

...

I woke up and it was already bright again.

The weather is a little gloomy today.

The wind blew on my body and felt a little chill.

It's really autumn!

Xu Chen couldn't help but slap him slightly.

Ye squatted alone in front of the stone wall beside the fire pit, looking at the moon phase picture above with concentration.

Seeing Xu Chen coming out, she quickly stood up and helped serve the rice.

Xu Chen urinated, washed his hands, washed his face, rinsed his mouth, sat by the fire pit and ate in a dizzy way, pointed at the moon phase picture with his chopsticks and asked, "I understand?"

Ye nodded slightly ashamed but quickly shook his head again.

Xu Chen no longer asked too much. It doesn’t matter whether he understands it or not, but this enthusiastic attitude towards learning is very good, much better than a group of savages who are like fleas all over the body when attending classes.

At present, Ye is more interested in learning in the entire tribe.

Although other savages often come to take a look with curiosity, they are becoming more and more confused about the more strange symbols on the walls.

Xu Chen once tried to ask Gu Heju to join in and study together, but the two of them only learned once and never came again. When they heard Xu Chen say that learning the word "two" and running faster than rabbits.

They would rather hunt, dig soil, carry stones and pick up firewood than sit still and look at the obscure symbols.

Xu Chen couldn't force this kind of thing, but fortunately, as time went by, the people of the tribe subtly learned many of his innovative words. If they continued to develop like this, sooner or later, a complete language and writing system would be formed.

He is not in a hurry to do this, he can take it slowly.

After breakfast, Xu Chen took out the weaving machine that was rolled together, found a flat place to sit down and continue weaving.

However, when I sat down, I found that the ground was very cold, so I couldn't help but grin and took a few breaths of cold air.

After the autumn begins, the weather is getting colder and colder every day, and it is not enough to sit on the ground every day. However, there are too many messy things in the tribe and everything is lacking. Fortunately, my savage is thick-skinned and rough and hard-working, and can still bear it for the time being.

Seeing Xu Chen starting to weave cloth again, Ye ran over and squatted beside him and watched carefully.

A group of children who were feeding the pony saw Xu Chen making another new thing he had never seen before, and immediately rushed over.

Tie the waist rope and hold the stick with both feet.

Improve the synthesis, divide the meridians, shuttle and hit the weft.

As the kakakawa weft knife gently patted it, the twine continued to increase one by one.

As he repeated it over and over again, Xu Chen's movements became more and more proficient.

A group of children were amazed at this complex thing and could only make various exclamations, especially the few little girls, who were watching it in a hurry.

"Understand?"

After more than ten minutes of weaving, Xu Chen raised his head and asked with a smile.

"Yeah!" Ye nodded seriously.

"Try it!" Xu Chen stopped, loosened his feet and unbuttoned his waist rope.

Ye shook his head nervously, but with Xu Chen's encouragement, he sat down, then tied his waist rope with Xu Chen's help and held the stick.

"Don't be nervous. The first step is to lift the hemi-rod...insert the warp stick...thread the thread...to hit the weft..."

Xu Chen carefully taught the weaving movements step by step.

Although Ye was nervous, he had already become familiar with the steps after watching so long, but suddenly he was a little busy. However, after Xu Chen taught it carefully several times, as the steps gradually became familiar, the movements gradually became smoother.

Seeing that Ye was able to complete the weaving movements alone and became more and more proficient in the movements, Xu Chen smiled with satisfaction.

Spinning and weaving cloth is relatively simple and boring, and only a careful and gentle woman can do it.

The most important thing is that this job does not require much physical strength, nor does it have any dangers. It is very suitable for women, children, elderly and weak who cannot do heavy work.

After the emergence of spinning and weaving, the women of the tribe will be busier in the future, but they will also create greater wealth.

After Xu Chen taught Ye to weave cloth, he greeted Gu Heju, who was making tools with a few adults, to go down the mountain.

“其 ~”

Seeing Xu Chen's vine basket on his back and was about to leave, the pony tied to the woods kept stomping his feet and neighing.

"Let's go, take you down!"

Xu Chen smiled and untied the rope. After thinking about it, Gu wanted to find two vine baskets, tie them together with ropes to make a basket and place them on the back of the pony.

“She…”

The pony obviously felt uncomfortable about the things placed on his back. He stomped his feet and raised his head and kept turning his head and neighing, and turned around and wanted to bite the vine basket with his mouth.

Xu Chen stroking and tickling for a long time, and the little guy slowly calmed down and barely accepted these two things that made him feel uncomfortable.

The vine basket is not heavy, it's just a little uncomfortable.

Xu Chen didn't put anything in it, but just let Xiao Ma slowly get used to the feeling of carrying things on his back.

Taming any wildlife is best started from a young age.

Although the horse would turn back and bite a few times on the way down the mountain, or deliberately jump and try to get off the vine basket, Xu Chen would either comfort him carefully or seduce some weeds, or let him do not let him succeed anyway.

So after a few twists and turns, Xiaoma also began to accept her fate and finally carried the two vine baskets down the mountain smoothly.
Chapter completed!
