Ten days later, the rain goose left the Yanshi tribe.

The reason she didn't stay here was because her mission had been accomplished.

Jia Chao, who sent away the rain geese, found that life had returned to peace.

Without hostile tribes to watch, the Yanshi tribe has once again become a small tribe that no one cares about.

So life was as calm as it was when I first arrived half a year ago, the only difference is that now the people in the tribe are busy working every day instead of looking for food.

In this hard-won peaceful day, Jia Chao practiced the Heavenly Dao inheritance that he had mastered every day, and he was only left to get tired of the stars and moon.

The two of them who pierced the window paper lived like a couple of old husbands and wives who had been in love for many years.

There is no need for too much communication, Jia Chao can do whatever he wants.

Xingyue will not pester him every day to ask him if he loves her, nor will she ask him to report his whereabouts at any time.

In her eyes, Jia Chao seemed to be just a cat who occasionally came to beg for water when he was thirsty.

This kind of relationship makes Jia Chao feel very comfortable.

Because whether it is the New Yanshi Tribe, or the Taoyuan New Village, or the spirit beasts of the crater, he needs to devote his energy to paying attention.

There is really no extra time to manage the relationship between men and women!

Over time, the trees in the mountains began to sprout.

This means that spring is coming!

Jia Chao commanded the elemental spirit beasts of the civil construction team to transform large areas of land into farms, which were designed in a chaotic planting mode.

In this way, although the crops on the farm have a certain uniformity after being treated as a species, they look like wild from the outside.

After the work of the civil engineering team is completed, it is the spirit beasts of the planting group that go out.

It's not too easy to plough the land with the power of the earth elemental of the elemental spirit beast!

And the tree frog that used to fly with the squirrel with the power of the mutated earth element was even more powerful, and it could directly turn a dry field into a paddy field with its swamp ability.

As a result, many of the slopes that look very chicken have been transformed into terraces.

After making these preparations, Jia Chao began to arrange planting.

He planted most of the seeds, leaving some of the seeds for each crop.

As for the sugar cane, he did not plant it himself, but handed it over to Bi Song and others, who originally belonged to the Sweet Tree tribe.

After all, this is the natal species of the Sweet Tree Tribe, and it is definitely the best solution for them to plant.

"Chief Ah Chao, don't you think it's right to draw like this!"

On the night after finally planting the sugarcane, Bi Song looked at the bright moon in the sky and was a little stunned.

Before Jia Chao assigned him a task, he had never observed the moon so carefully.

At this moment, the moon is so big and so round, and it illuminates the whole earth as bright as day.

"Show me!"

Jia Chao took the animal skin handed by Bi Song, and saw that some moon patterns were scribbled on it, and some marks were made.

This world also has a moon, and Jia Chao's task to Bi Song is to make a set of calendars starting from observing the moon.

Bi Song has been recording the changes of the moon since New Year's Day in the first year of Kaiyuan.

The changing forms of the moon in this world are also about eight forms:

New Moon, Moth Eyebrow Moon, First Quarter Moon, Waxing Gibbous Moon, Full Moon, Waxing Gibbous Moon, Last Quarter Moon, Waning Moon.

The first round of these patterns is January.

What's weird is that, judging from the results of the current statistics, the month in this world seems to be very regular.

It's all a reincarnation of thirty days!

Jia Chao looked at the moon map drawn by Bi Song, and couldn't help muttering in his heart.

Could it be that this world is really man-made? How else could it be so regular?

It is important to know that the trajectories of celestial bodies are mostly elliptical, and when the trajectories of two ellipses cross together, people observe different information.

This is also why the month of the previous life was divided into long and short months, and it was also divided into leap years and leap months.

However, Jia Chao did not dwell on this issue for too long.

"Divide each month again, divide it into seven days into a week, and then give the clansmen one day off every week, so that everyone can have time to rest!"

Jia Chao is not a capitalist, where will he let his people go to work?

At most, ninety-nine-six, not zero-zero-seven!

Bi Song listened to his instructions and thought for a long time with half-squinted eyes.

Holiday?

What is Fake?

Why take a holiday?

Isn't it true that you can rest when you want to?

He always felt that he and his people had lost something, but he couldn't say exactly what it was.

Only Jia Chao knows that that thing is called freedom.

The moment work was invented, freedom was gone.

Of course, Jia Chao didn't intend to tell people this cruel truth.

Because for people today, hunger and cold are the biggest enemies.

The treatment they gave them this winter made them much happier than in previous years.

Why do you want to be free?

After confirming with Bi Song that there was nothing wrong with the formulation of the calendar, Jia Chao went to find Shuoshi again.

Shuo Shi is one of the planners of the Taoyuan New Village project, and has a better understanding of the construction of sanitation facilities in the tribe.

Jia Chao needs to know how the household waste that people make is disposed of, especially the feces.

The fertility of the land is limited, and the crops must be fertilized to guarantee a harvest.

Under Shuoshi's leadership, Jia Chao finally found a sewer outlet in a depression south of Taoyuan New Village.

A large amount of domestic sewage is discharged here without any treatment.

The whole depression is already stinking, and it won't be long before it becomes a foul-smelling quagmire.

Since the Yanshi tribe moved into the crater after the winter snow fell, Jia Chao didn't notice this problem at first.

Obviously, it was a bit reluctant for Shuoshi and Bi Song to design the miniature town of Taoyuan New Village.

There are still some limitations in primitive thinking.

Jia Chao immediately proposed the task of optimizing sewer sewage with Shuoshi, and explained to him the design of septic tanks.

"Go find Brother Maoyu and think of a way, don't look for Sister Heye, she is not suitable for heavy work now!"

After telling Shuo Shi a series of ideas, Jia Chao went back to the tribe to wander around.

He needs to thoroughly understand the structure of Taoyuan New Village as soon as possible, and discover those unreasonable hidden dangers in time.

Especially in terms of hygiene.

At present, there are not many people in the tribe, but there are many domestic wastewater and garbage generated by hundreds of people eating and drinking in their daily lives.

If it is not solved in advance, there will be potential safety hazards after all.

In case of an epidemic, maybe the race will be wiped out!

I don't know how the Hundred Bird Tribe dealt with it, after all, such a big tribe, there are many more people living together than the Yanshi Tribe!

When do you still have to go out! Behind closed doors there is no future!
