Yun has been researching herbs because he is interested in herbal medicine. Through his contact with Ding Qi, he learned a lot about herbal medicine and recorded the characteristics of herbal medicine. Since he came to the tribe, he has been the most active person in terms of learning Chinese characters and mathematics.

Only the rhinoceros has no research or responsibility for the time being, and usually follows the elders to carry out activities with them.

Ding Qi summoned them over, firstly, to understand the progress of the matters they were responsible for, and to help them sort out their own problems and solutions, or research directions. The well-informed Ding Qi can give you the most comprehensive guidance.

Sitting on a stool in the shade of a tree, everyone speaks their own content, and the others add to it.

At the end of the day, the rhinoceros was a little overwhelmed. Everyone else has good results or research results, but he has no achievements, and he feels a little idle, which makes him a little embarrassed.

Ding Qi knew what he was thinking, so he was very comfortable and entrusted him with an important task: the observation of the sun and the moon and the formulation of the lunar calendar, including the formulation of the 24 solar terms. To put it mildly, he is an astronomer who engages in astronomical observations!

One advantage of this work is that Tinch is able to get an approximate estimate of the current month, which can be roughly judged from his mechanical watch. But this is the Gregorian calendar, and it needs to be carefully discerned. It was not an easy task, but the rhinoceros accepted the job with great pleasure.

Tinch wouldn't let him do it alone. The first is to let him choose one or two smart children from the tribe and give him a hand, and the second is to let him communicate with Yi, because the lunar calendar and the 24 solar terms are closely related to agricultural production.

In fact, the work of the six of them is arranged for apprentices or students to learn from them, which involves the issue of inheritance. If a tribe wants to develop for a long time, inheritance is very important, including bloodline, language, knowledge, culture, wealth, technology and so on.

When it comes to inheritance, Ding Qi feels that there is one work that is imminent, and that is papermaking. This is an important task that touches all aspects of tribal life, and it is a vehicle for the tribal legacy. At best, it is the inheritance of knowledge and technology, and at the worst, everyone needs it to go to the toilet.

Ding Qi is now fed up with wiping his butt with bamboo chips and sticks, although he has adapted to this method, and even wiped his butt with dirt when he was a child. But now there is an opportunity to solve the problem of wiping the butt by no longer using foreign objects such as bamboo chips, so it is urgent to get it done as soon as possible, even if it is just a rough paper!

Who can understand Tinch's suffering?

The work has been arranged, but it can't be done without tools, and the reason needs to be clarified.

The tools used to measure time and the length of the sun were called sundials and gui watches in ancient China. The sundial is a stone disc-shaped object with a thin metal pole in the center of the circle, which is divided into 12 grids according to the format of a clock, each corresponding to two hours. The time is determined by the projection of the metal pole on the disc by the sun shining on it.

The Gui watch is even simpler, using the length of a pole projected on the ground at noon to determine the 24 solar terms. The longest day of the projection is the winter solstice, and the shortest day is the summer solstice. The 24 solar terms are used to guide people in agricultural planting and harvesting.

Everything is difficult at the beginning, I am afraid that I am willing to climb, not to mention that there is a BUG-like existence here: Ding Qi. As for the details of the observation or research stage, it is necessary for the person in charge of the matter to study and determine the specifics, and the principle can be explained.

The above two things used to observe the sun must be assisted by a tool that determines due north and south, that is, the guide

Needle. This thing, which is one in Tinch's backpack, can help the rhinoceros to orient himself.

Then Ding Qi arranged for the two of them to polish and carve a disc, which must be perfectly round. For this reason, Ding Qi made a compass for him to draw a circle on the spot, and this compass was also learned by Jing on the spot. After determining the center of the circle, use Jing's carpenter drill to punch a hole in the center of the circle and insert a copper needle. The length of the copper needle and the size of the disc were discussed between the rhinoceros and them, and Ding Qi did not care.

Moreover, the sundial that Ding Qi is going to make is horizontal, and it can't do the kind of sundial that is aimed at the north celestial pole and the south celestial pole is high in the south and low in the north.

Later, he arranged for Jing to make a table. The table is simple, but the work is meticulous. In fact, the best way is to use metal to make it, such as using bronze to make a rectangular plate-shaped gui, and using bronze needles to make a table. If the technique is not enough, make a stone table-shaped watch, as long as it is not easy for people to move. Don't let people move, because they are afraid that the direction will not be accurate, which will affect the observation results.

In the early stage, in order to let the rhinoceros understand the principle of observation, they can make a wooden one, and come back to make it slowly, but this thing is not in a hurry, it is considered to find something for the old man to do.

After these things were resolved, he took people to check the growth of soybeans and millet. Happily, the soybeans and millet have sprouted, and a small bud bundle has been lifted up, exposing the ground. Ding Qi is very happy, his heart is very sufficient, and there is even an expectation in it, which may be the mood of farmers planting crops and looking forward to a bumper harvest!

Ding Qi carefully explained to Ben that soybeans and millet sprouted, so that they could distinguish them from ordinary weeds, so as not to remove the crops together when weeding.

The pepper seedlings have grown very well, and they have already straightened their waists. This is the mother of the mother, how many chili peppers will be traced back to the source in the future, and Ningcheng will be the source.

Here again, let's talk about the origin of Chinese chili peppers. In general, it came from overseas during the Ming Dynasty. However, in modern times, scientists have found wild-type millet peppers in the primeval forests of Xishuangbanna, Yunnan Province, and wild yellow peppers in the Shennongjia area of Hubei, which can prove that China is also the birthplace of peppers.

The rice seedlings are also growing well, and they should be ready for transplanting in three days. As for chicken head rice, gourd and water chestnut, etc., it can only be seen how well the seeds germinate and grow by themselves.

The next day, Ding Qi led a group of people who were learning to farm, including Ben and Yi, to the paddy fields. Since there was no suitable ploughshare for the paddy field, Ding Qi arranged for twenty people to come over, go barefoot and plough the ground with their feet. Just like fishing in troubled waters, stir up the mud in the field as much as possible, and achieve the purpose of fully ploughing the ground.

After the mud has completely calmed down, the excess water in the paddy field is drained and the rice can be planted.

On the third day, Ding Qi led them to the paddy fields again. First, we taught everyone how to dig the seedlings out of the nursery with wet mud, and then send them to the paddy field, and put some seedlings at intervals.

When the seedlings are ready, transplant them immediately.

To be honest, Ding Qi himself has really never planted seedlings, he has seen it in film and television or Internet materials, saying that after inserting it, the roots should be slightly raised, so as to improve the survival rate of seedlings. As for the rest, it was not clear, and it was up to his tribesmen to slowly explore.

Of course, rice cultivation is the same as other crop cultivation, and the crops generally grow well by increasing the ventilation and lighting area. Therefore, when Ding Qi planted seedlings, he used the method of wide rows and narrow plants.

I did a demonstration, and everyone who brought it came up and tried it, and planted the seedlings in the soil. Ding Qi has to watch everyone's way of planting seedlings and try to ensure that the seedlings survive. Seedlings are precious, Ding Qi has calculated, the germination rate of the rice he sowed in before has not even reached 60%, so that now after adopting the method of transplanting rice with wide rows and narrow plants, he has not planted it

Full acre of land.

However, Ding Qi is not in a hurry, as long as this batch of rice can survive and carry out artificial breeding, the traits of rice will change very much. Yi has to start researching in this regard, and even put aside the cultivation of peppercorns. Therefore, I don't know if he will be the father of hybrid rice, but he must be the first to start artificial rice cultivation.

Although there is a lot of wild rice in Shirasawa, history is written by the victors, isn't it?

After planting the rice, Ding Qi made the next step of the tribe's work arrangements, and after these things were arranged, Ding Qi was ready to start exploring the Wild Horse Valley.

The first thing to do was to arrange for Zhuang to lead two squads of warriors to his original tribe and try to recruit their tribe to surrender. At the same time, from that cannibal tribe to the east, west, and south, to promote the wealth of the Ding tribe and Ningcheng, and attract more people to join the tribe. His duties are the same as moo, which is propaganda and communication.

The training of new slaves was entrusted to Xiong.

After Zhuang left, there were only four squads of warriors left in the warriors of the tribe. If Ding Qi takes two more squads of fighters, then only two squads of fighters will be left to be responsible for tribal patrols and defenses. To this end, Ding Qi selected fifteen people from Xiong's platoon to serve as the squad leader of this group of slaves, and selected some people from the Blue Bird and their tribes to join, so that the number of the entire newly formed slave battalion reached 200 people, and the number of people in each squad reached about 13. The position of the temporary acting battalion commander (non-military rank, he is still the company commander) is trained and managed by Xiong, and the positions of several platoon commanders remain unchanged, and they will be integrated after the number of tribal troops increases.

Cang knew that he was the company commander, but the supreme commander of the tribal army was the leader of Dingqi, and everyone swore allegiance to the leader of Dingqi.

Of course, the slave barracks are just a title, and the deeds of the Ding tribe treating slaves well, their group has heard about it for a long time. As long as you can survive a year, you can become a real Ding tribesman.

As the lord of Dingcheng, the buck is responsible for the daily affairs of the entire tribe, running to assist and plan the tribe's agriculture and defense. The Elder Group and the Witch Doctor Regiment each have their own responsibilities and cooperate with the bucks to strengthen the management of their own clans and the use and distribution of clan tools. Now it's like the big pot rice period, unified work, unified return to the city, tools handed in, unified registration and distribution.

The rainy season is coming soon, and there have been several rains during this period, and the rain is relatively heavy, but the duration is relatively short, and the impact is not great. But if it's the rainy season, there is a risk of flooding, and the tribe needs to pay attention.

The fish skin shed has been handed over to Ben, and he will harvest the cabbage seeds and green onion seeds, dry them and keep them.

The horns are in charge of boiling wool, and it has long been coming to an end. Sixty or seventy sheep spent a lot of time from shearing sheep, boiling wool to spinning wool, and even Qiao'er joined in the magical work of spinning yarn and put a lot of energy.

When the sheep horn heard the leader say that the size of the flock should be increased, he fainted. Why? Tired, smelly and tired, boiling wool is a sinful job. Fortunately, Ding Qi promised him that after knitting a sweater, he would be rewarded with the first piece, which finally gave him the courage to face boiled wool.

The shipbuilding on Jing's side is progressing well, and a new model has been built and glued with bone glue, and the effect is very good. I tried it in the lake, and it was a little leaky, but it didn't have much impact and it could drain the water.

Ding Qi himself sat on the boat for a sea trial, and felt what it was like for the first ship in the primitive period to float on the water.

Refreshing!

With a gentle wave of its oars, the wooden boat slowly paddles away from the shore and floats in the water. The white sturgeon, which had rushed over to join in the fun, swam around the wooden boat, apparently expressing extreme excitement that Ding Qi could "swim" in the water like him. From time to time, it jumped out of the water, causing a large splash, but it frightened Ding Qi so much that he was always worried that the waves would overturn the small wooden boat.
