The two dishes, combined with the boiled meat and grilled fish prepared by the tribe, made everyone eat very refreshingly and full. Especially the spicy stir-fried venison with lotus root, the crisp and spicy taste makes everyone addicted. And the taste of honey pork ribs almost made the deer swallow his tongue and fingers.

Ding Qi made a discovery that under the abundant food supply of the tribe, everyone gained a lot of weight, of course, it can also be described as strong, after all, everyone has to do a lot of high-intensity training and work after eating and drinking.

In fact, they have been in the tribe for less than a month, and their average weight has increased by ten to twenty pounds. Then the tribe began to select warriors, build Ningcheng, daily hunting and other activities, and the body began to change from the perspective of fat and became stronger.

Most people's weight is increasing by about 20 pounds, and after entering the state of a toned body from a thin hemp pole, the weight has basically not increased again. But there are several special characters in it, one is a bear, one is strong, and one is Ling.

The two bears and strong have been increasing in weight, and their bodies are also increasing, developing in the direction of human-bears. However, Ling has not changed much, and her weight has not increased or decreased after only five or six pounds, but she is not strong, but her body is still vigorous. The arms, which are much larger than ordinary people, are very enviable when shooting arrows, not only with greater accuracy.

There is another group that is gaining weight, and that is women. Ding Qi demanded that each woman must weigh 120 pounds, and she had to eat if she was not fat until she was fat. If she doesn't get fat, she is not allowed to have children.

Why?

Because Ding Qi is thinking about women, but also for the sake of the child in their womb, I want her to give birth normally and be safe with mother and child.

Ding Qi once read a book that said that if a woman wants to have normal fertility, the fat content in her body must reach a certain proportion, and if the fat content is very low, it is very likely that she will not be able to get pregnant. He remembered that it was 40 percent, but Ding Qi thought it was an exaggeration, because a woman with 40 percent body fat was obese.

Later, he looked at some information and found that the development of the ovaries can promote the increase of weight and body fat in women, and many phenomena have also proved that weight or body fat is necessary for the normal function of the ovaries. The body fat content must reach 17% of body weight before menstruation can begin; To establish regular ovulatory menstruation, the amount of body fat must reach 21-25% of body weight.

Pregnancy, childbirth and breastfeeding are a burden on women and require adequate amounts of fat for energy. When the body weight is too low to cope with this burden, the human body automatically stops the reproductive function temporarily in order to protect itself. For women in adulthood (age 16-39 years old), the body fat percentage should reach an appropriate ratio, such as 25%-30%, so that the proportion of successful births will be greatly increased.

Therefore, there is also a reason why Tinch asked the tribal women to increase their weight.

In addition, Ding Qi also asked women to do more physical exercise activities, such as sit-ups, running, and doing maternal exercises during pregnancy, which are all activities that help women have a healthy body and improve fertility and childbirth.

After the meal, Tinch took the deer by the hand and went to the house of the elder of the buck to visit his brother-in-law. Now the little guy who is almost two months old eats white and fat, and eats, sleeps, sleeps and eats every day. But every time Ding Qi came over, he was very excited, even if he was sleeping, he would wake up immediately and smile at Ding Qi.

The little guy's performance amazed everyone, and he could only attribute these to the aura of the Aragami affecting him.

It was the same this time, he had just come out of Aunt Mei's arms, and when he heard Ding Qi's voice, he immediately turned his head to look at Ding Qi, and opened his hands to ask for a hug. This scene made Elder Bucks cry and laugh, in the end, Ding Qi is his brother

Is it a strange Shu millet? The attraction is too great!

Ding Qi hugged him to play in the courtyard as usual, and even sat on the little cutie's back and walked around twice, causing the little cutie to pull her ears, unwilling to take care of Ding Qi, and swore never to follow Ding Qi here again. But every time it had to come along, be ridden twice by the little one, and then regret it.

Up to now, there are more than 200 new children born in the tribe, but unfortunately there are some babies who have died, and the proportion is not high, about 11 or 2. Such a high infant survival rate is definitely due to Ding Qi's large part of the credit. In the seventies and eighties of the twentieth century, he implemented the operation method of rural midwives, which greatly reduced the infection rate of some maternal diseases or inflammation. Of course, this is not the most important thing, the most important thing is that the abundant food and milk supply provide them with the energy to survive.

Tinch had heard from Elder Stag that the tribesmen of the past often changed their living places because they had to change their gathering and hunting grounds from time to time, making it inconvenient to carry more children. As a result, a woman of each adult age has a maximum of two children and does not raise any more children, and the interval between the births of each child is longer, usually four to six years, and some reach six to eight years. Another reason is that people in primitive societies expect to live too shortly, and their thirties are considered to be long-lived. As for some of the older doctors, such as the Blackwater Tribe doctors, they are all old elves!

If a woman finds out that she is pregnant again or has to give birth to that child while her last child is still young, they will use methods such as abortion or infanticide to keep the child's birth interval to more than four years. In this way, her children can grow up and follow the tribe quickly, so that she will not become a burden, and she will have the possibility of having another child.

It was frightening news for Tinch, who first heard the message, but it was prevalent among the tribesmen, especially those who wandered everywhere.

Therefore, a more scientific explanation is that the current settled life makes women of childbearing age invisibly produce a message to give birth, which imperceptibly affects their fertility mode. Subconsciously, they believe that they will have a stable life and enough food to meet their fertility needs.

But in Ding Qi's view, it is nothing more than another way of expressing "full of warmth and lust". It's a bit one-sided, but why not?

In fact, not only the Ding tribe, but also other tribes that were the first to accept the favor of the Ding tribe, such as Baishui and Bai Ze, while obtaining abundant food, the number of pregnant women in the tribe also increased.

Tinch believes that with the advent of better hunting tools and the cultivation of more food crops, more tribes will be settled and more people will be born. Especially in the next year, when a large number of food crops are promoted, the number of human beings will develop by leaps and bounds.

Well, a child born in that period will ask his parents when he is seven or eight years old:

"Why are there so many children my age?"

Their parents would surely say something like:

"Because Aragami has brought food to the tribesmen, they can eat a full stomach."

Because all of this is because of the existence of the Aragami, more people appear in the Great Wilderness. But due to the rapid increase in population, an even more chaotic famine will also appear. This may have been something that Tinch had not expected, or perhaps something that he had expected.

The battle for turf will appear anywhere.

Aunt Mei, who is a mother again, will nag every time she sees Ding Qi and Lu coming, asking them to get married and have a child quickly, and then Ding Qi and Lu's children can play with his little uncle, so that their relationship will be closer.

Every time he said this, the deer would cast a resentful look at Ding Qi, and he was really embarrassed to see that he was a heinous person

The big bad guy is like a big villain, hesitating to give up the set directly, come to a straight smash Huanglong, and give birth to a doll. But every time, I will be persuaded by another voice in my heart that we must have good births!

Fleeing back to his residence in embarrassment again, Ding Qi lit a butter lamp, picked up a bamboo pen, dipped it in the ink sweat mixed with tung oil, pot ash, and pine ming, and began to write elementary school mathematics knowledge on straw paper.

Most of the knowledge I learned in the tribe was based on the basic operation of numbers, such as multiplication, division, triangles, circles, and squares. Recently, everyone's learning content has come to length, distance and speed, because Ding Qi stipulates the basic unit meter, so everyone has a high degree of acceptance.

But there was an embarrassing scene in the specific calculation. For example, if you are 50 meters, someone will hold a meter ruler and make everyone understand that it is 50 meters after you have crossed it 50 times. But by the time it came to a kilometer, it had already exhausted the students and the people presenting.

It seems that there is a long way to go, and you still need to study hard!

The content of Ding Qi's drawings will be handed over by the deer to Xue and Dan for classification the next day. As for the teaching of words, thanks to the availability of paper, the preservation of words and the learning of words are more convenient and simple. These tasks are undertaken by teachers such as Xue and Dan.

The weather is getting cold every day.

The busiest in the tribe, in addition to the hunting team, the fishing team, and the forage gathering group, are the tanners, the garment team, and the charcoal burning team.

The most important thing in winter is to keep warm, so the tanners have to make enough leather before the winter freezes for the garment team to make animal skin clothes. They are responsible for the supply of raw materials, and if there is not enough leather, the work of the garment team will come to a halt. Therefore, the size of the leathersmith team in charge of Niu Er has expanded to fifty people, and they are so busy that they don't touch the ground.

The garment team is even busier, in order to ensure that the tribe has two sets of animal skin clothes from the top of the tribe to the slaves below, their size has directly risen to one hundred and twenty people, and there are still some female slaves being trained, and the number will soon exceed two hundred.

The garment team is now divided into three groups, the largest of which is the traditional animal fur clothing group. The second group is the group that knits sweaters, there are not many people, there are only ten, and they sit there with only one thing a day, knitting sweaters. After exploration and learning, more than 20 sweaters have been knitted, and the quality is gradually improving. However, there is a need to continue to expand production capacity, as the last batch of wool of the year is almost ready for the horn boss.

The third group is the spinning group, which is spinning yarn according to the method of yarn weaving. There are not many people, only six, but their work is very important. Because in the winter, the six of them have to train a large number of people to spin thread, and there is a lot of kudzu fiber in the warehouse. Whether the large-scale textile production in winter can succeed depends on whether the six of them can afford this responsibility and let more people master the ability to spin threads.

The third busiest squad is the charcoal burning team. The vast majority of these people are slaves who have been exchanged. Although the work is hard, the food and food are the same as everyone else, and the captain and the supervisors treat them very kindly and will not beat or scold them. In particular, they know that after one year in the tribe, they can become full members of the tribe without making a big mistake.

Therefore, they are all very hard-working, and they give 12% in their positions.

After breakfast, Ding Qi came to Jing's carpenter group again. Busy making snow climbing plows and other tools for snow use, Jing had already suspended the construction of the big ship and devoted all his energy to it. In this tense and busy space, Ding Qi arranged another job for Jing to study and manufacture looms.

The fibers of kudzu are already being spun into threads, and the next step is how to use these threads to spin arrowroot cloth, which requires Ding Qi to constantly draw pictures for Jing next to him, so that he can understand the style of the loom and the principle of weaving.
