The cold moon casts its clear light, and the branches with fallen leaves appear even colder in the moonlight.

Inside the row of houses, the orange-yellow firelight was blocked by the animal skins covering the windows, making the skins appear a little red, but not letting in any light at all.

Occasionally, a blurry human figure would be reflected on it, and it was unclear who was walking in the room.

The dense fur blocked the firelight but could not block out the sound. From time to time, laughter and joyful chatter could be heard from the houses in a row, adding a bit of liveliness and warmth to this peaceful yet cold night.

The three people who were on guard duty on the low wall were wrapped in thick fur, wearing gloves and hats, and walking around in a small area with their necks tucked in. They would stamp their feet from time to time to drive away the cold.

In the courtyard, two people and a dog squatted side by side in the moonlight, raised their heads and exhaled white air, looking up at the bright starry sky together.

If we exclude these two people, we can see the real version of "dog looking at the stars"...

The two people looking up at the stars are not big in stature, but they are wrapped in thick fur and squatting there, looking a bit like two furry balls.

One of these two people is Shitou who dreams of flying and is ready to take a roundabout way to realize his dream, and the other is Han Cheng who was upset and wanted to be quiet after discovering that he failed to make charcoal again after opening the kiln today.

Shi Tou looked at it for a while, then lowered his head, took his hands out of his warm gloves, picked up a tile that had obviously been polished and was more conducive to writing, carefully lifted the upright pottery plate and placed it flat in front of his eyes, then bent down and carved on it with a pen made of the tile in the moonlight.

This is a circle that is gradually becoming fuller, and its shape is very similar to the half cold moon hanging in the sky.

In front of this seemingly full circle, there are five horizontal rows of circles of different shapes.

At the tenth place in front of the circle, there is an x. There are not one x but three in a row. This is the solution Heiwa got after he did not see the moon for three consecutive days and did not know how to record it, so he came to ask the Son of God for the solution.

Shitou is a 'problem' teenager who has even more problems than Wu, the 'problem' old man. He often asks the Son of God questions about things he does not understand.

He had asked the Son of God about this question a long time ago: why do we have to write horizontally from left to right when recording something, instead of vertically from top to bottom or from right to left?

Of course, Han Cheng would not tell Shitou that this was a habit he had developed since childhood, and he would not say something like "When writing and reading vertically, one nods frequently to show one's agreement with the words of sages; when writing and reading horizontally, one shakes one's head frequently, which is disrespectful to the sages."

The method Han Cheng proposed was very simple. He asked Shi Tou to write a story titled "The Tadpole Looking for Its Mother" horizontally and vertically on a ceramic plate and then try to read it.

Shitou, who was led astray by Han Cheng at the beginning, felt that it was more comfortable to read horizontally from left to right after reading it twice, so he stopped asking this question.

Han Cheng looked at this extremely precious stone pottery plate, which had more than forty irregular circles carved on it.

Han Cheng nodded slightly, and after carving for a while, he would be able to guide the stone to summarize the rules.

After the patterns of the moon's waxing and waning were summarized, the lunar calendar with the moon as its symbol was able to take shape.

After having a rough framework, we can slowly add "big months", "small months" and "leap months" into it, and make adjustments based on the actual situation.

With himself as a time traveler and Shitou, the next witch brought to the field of "astronomy" by him, he can always come up with a calendar that is more suitable for them.

Shi Tou carefully carved the circle with some missing parts, compared it carefully with the bright moon in the sky for a while, made some modifications, and then stopped.

He carefully put the 'pen' made from tiles into the side pocket of the simple clothes he was wearing, and then carefully stood up the pottery plate in front of him, and then looked up at the moon that made all the stars in the sky pale in comparison.

"Son of God, are there trees on the moon? Are there tribes living on it?"

After looking up for a while, Shitou finally asked the Son of God what was on his mind.

These are what he discovered while observing the moon during this period, and the beautiful aspirations that arose from it.

At this time, there is no worrying haze, no dazzling lights, and without heavy schoolwork, the eyes are not nearsighted, so one can see the shadow on the bright moon more clearly.

Han Cheng, who came from the future, knew that there was nothing above the bright moon but only desolation. However, when he saw Shi Tou's eyes full of longing and expectation, Han Cheng held back and did not speak out this cold reality.

Sometimes, beautiful and white lies are more necessary in the world than the discouraging reality.

Han Cheng nodded.

He looked at Han Cheng's stone with both anticipation and trepidation in his heart, and a smile suddenly broke out on his face when he saw this.

But the smile on his face soon froze, because after nodding, the Son of God shook his head.

Looking at the surprised and disappointed stone, Han Cheng smiled and said, "There are trees and people on it, but no tribe."

The hard smile on Stone's face bloomed again.

He looked at Han Cheng with full expectation, hoping that the Son of God could explain it a little more clearly.

Han Cheng pointed at the bright moon and said, "See? That's a big osmanthus tree. Under the tree, there is a rabbit pounding medicine."

Shitou's eyes widened as he listened. He looked at the bright moon carefully. After what the Son of God said, he seemed to really see a big tree and a rabbit doing some exercise from above.

He didn't understand what the Son of God meant by pounding medicine, so he automatically transformed it into a kind of exercise.

As I watched, the question came up again: why is there a rabbit on it? What is it doing 'pounding medicine' for?

Stone looked up at the bright moon and began to ask the Son of God with extreme anticipation in his heart. His body was trembling slightly, not knowing whether it was because of excitement or because of the cold.

Han Cheng secretly apologized to Houyi and Chang'e, and told them to let them suffer the same injustice as the Weaver Girl.

Then he thought again, and felt that Chang'e and Houyi had not suffered as much as Zhinu, because they were both people from the ancient times.

Han Cheng thought for a while, then told the original version of Chang'e flying to the moon and Houyi shooting down the sun.

Looking at Shitou looking at him in astonishment and speechless expression, Han Cheng's depressed mood caused by the continuous failures in making charcoal improved a lot.

"Chang'e deserves death!"

An angry voice suddenly came from not far away, scaring Han Cheng.
