After stepping down the road of civilization, the giant aborigines in the wild world are now living a happy life. They have more power, can get more adequate food, do not have to go hungry because of food shortage. They have the use of fire, can eat cooked food, eliminate many gastrointestinal diseases, and can more easily absorb the nutrition in food.


    The use of metal tools has made the life of the giant aborigines a step forward. While giving better play to their own strength, it has also brought many conveniences to their daily life. For example, although they can''t spin and weave cloth, they can already make better animal skin clothes with the help of sharp metal tools. For example, they made metal saws and axes, which can obtain wood more quickly and build wooden houses much more comfortable than caves.


    Of course, as the first tribe to get guidance, the tribe named "Yan" now naturally goes faster than other tribes on this road.


    It is the so-called "thinking about that" and "Yan" tribe, after solving their livelihood problems, although they don''t really think about "that", they are no longer satisfied with the status quo. They wanted to expand their tribes, and were no longer satisfied with just a few hundred people, so they naturally turned their attention to the surrounding tribes.


    In fact, the expansion of tribes is also the demand of tribal development, not just to rule more people and control the power of life and death of more people. At this stage, they did not have a deep understanding of power, and the patriarchs had more privileges in clothing, food and housing.


    People always yearn for a better and better life. Few people will just be satisfied with starvation. When people will not starve to death, they will consider how to eat better. When people won''t freeze to death, they will consider how to dress more decently. When "satiety" and "warmth" have reached a certain level, people will have to consider higher spiritual pursuit.


    After the "Yan" tribe had stronger power and various better weapons and tools, of course, the hunting efficiency was much better than before. However, after they can hunt more prey, they naturally want to enrich their menu, such as adding fruits and vegetables to the menu.


    Therefore, in addition to hunting, the tribe also needs someone to pick fruits and vegetables and fish. Just a food problem, although they are no longer worried about starvation, they have more demand for manpower.


    In addition to eating, there are many aspects that need manpower.


    For example, in terms of metal appliances, first someone needs to mine the ore, then someone needs to smelt the ore, and finally someone needs to cast and polish the appliances. The more developed the tribe, the greater the demand for the population.


    It is reasonable to say that just stepping into the road of civilization and solving the most basic needs of clothing and food, it will take some time for other desires to grow. However, the civilization of the giant aborigines was secretly guided and spawned by Ye Zan, especially with ready-made languages and words.


    The languages and characters used by the giant aborigines are "carried" by Ye Zan directly from the monastic world. However, the language used in the monastic world is accumulated after the development of monastic civilization for countless years. As a result, some descriptions in language and writing are too advanced on the side of giant aborigines.


    Normal civilization, in the process of forming language and characters, should create corresponding language and characters in order to describe new things every time a new thing appears. However, the giant aborigines, on the other hand, got complete languages and words far beyond the current level of civilization in advance, with a large number of descriptions of things that did not appear.


    At the beginning, when the old priests of "Yan" tribe got language and characters, they were not simply engraved characters, but indoctrinated with the meaning of language and characters. In other words, the old priest completely "inexplicably" understood the meaning of words describing things that did not appear.


    For example, there is the word "house" in the language, but the giant aborigines who originally lived in the cave did not have a real house to correspond to the word "house". Therefore, according to the meaning of the word "house", the giant aborigines knew in advance what the "house" was. Through the word "house", they know that there is another way to shelter from the wind and rain in addition to the cave.


    Therefore, through the interpretation of these languages, the giant aborigines seem to have been enlightened by God. Without long groping and waiting, they can know a lot of new things in advance and think of ways to make those things real.


    It can be said that the indoctrination of language and words is tantamount to opening a preview of the science and technology tree to the giant aborigines in advance. They can see how their civilization should develop from the language without waiting for any unexpected ideas.


    Another example is "wine". In the normal development of civilization, the emergence of wine may be due to some accident, which leads to the fermentation of stored food, and then makes people find a way to make wine. Maybe, if this civilization has not had this accident, wine has been delayed. God knows whether there will be wine in the end.


    However, when there is no wine, you already know the word wine and its meaning, and know "wine: a drink produced by food fermentation". So, can you try to see if you can get the "wine" in the text by storing some grain?


    Why, after solving the extraterrestrial evil, ye Zan doesn''t need the Lin family to guide the giant aborigines? To a large extent, it is for this reason that all guidance is already in the language, and naturally there is no need to guide anything. Unless, the giant aborigines are so stupid that they can''t understand anything from the language.


    The reality is that although the giant aborigines are tall, they are not "simple minded and developed limbs". As the only intelligent creature in the wild world and the darling of the original will of the world, how can we not understand the mystery in language.


    Back to the "Yan" tribe, it is because there are already languages and words, and we have learned a lot from them. Therefore, although it is only a short year, it is enough for them to make the manpower of the tribe more and more stretched in one "fantasy" after another.


    One way to increase manpower and the number of people in the tribe is naturally to have more children. However, the waiting time between a child''s birth and becoming a labor force is not a matter of years. Even a giant cannot violate the growth law of life. A giant''s baby is still a baby.


    In addition to relying on reproduction to increase manpower, another faster and more effective way is to annex other tribes. As long as we annex other tribes and merge the populations of other tribes into our own tribes, our own tribes will naturally have more people available.


    Therefore, expansion is very natural and has become the only solution for the "Yan" tribe to solve the human problem.


    When ye Zan and others were closed, the "Yan" tribe launched a strategy against other tribes around by relying on a little advantage in civilization. By the time ye Zan and others solved the extraterrestrial evil and returned here again, the "Yan" tribe had become the only giant indigenous tribe in the area controlled by the original five ring high tower.


    In addition, due to the same language and characters and the same belief in God, the unification war of "Yan" tribe was not fierce and bloody. At best, some of them are more desperate. They have to hold on to the title of their own tribe, and finally die with the title of their own tribe. The vast majority of the giant aborigines are not so resistant to changing tribes. They have to work everywhere anyway.


    After merging several neighboring tribes, the "Yan" tribe has reached thousands of people just because of its labor force. As for babies, children and so on, they are not included. After all, even the so-called half boys, with the productivity that the giant aborigines now have, don''t have to use child labor.


    After a large population, the "Yan" tribe also chose a new place of residence and built a large number of houses on the new place of residence. Let Ye Zan''s "normal people" see that the new residence of the giant aborigines may have been called a giant city. But in fact, this is just a village with thousands of people.


    In this giant village, giants have their own division of labor. The hunting team did not cancel, but still went out to hunt on time. After all, for now, hunting and gathering are still the main food source of the tribe. In the village, some people are responsible for planting large areas of land, and others are responsible for raising some domesticated animals. These things can only be regarded as investment now, and the harvest will wait until a few months or even a year or two later.


    In addition, not far from the giant village is a copper mine, where a mining team composed of dozens of people continues to mine ore. Several huge rough carts, using round wheels cut with log slices, were pushed to the metallurgical field in the village after being filled with ore.


    There are hills of ore piled up in the metallurgical field. A dozen giants who stimulate and master the blood power of fire are responsible for smelting those ores into metal, and then casting various metal appliances.


    Now, the giant Aborigines have not mastered the real forging technology, so they can only cast with simple molds. As a result, the performance of metal appliances is not very strong, and there will be great loss in use. This is one of the reasons why they need to continuously cast metal appliances.


    Moreover, even those worn-out metal utensils can still be remelted and cast, but more spare supplies should be prepared.


    In the center of the tribal settlement, on a large open space, some children sat there obediently, listening to the old people in the tribe teach language and writing.


    Although giant children like to play and make trouble, there is no saying that corporal punishment is not allowed here. If you dare to make trouble, you will really be beaten to death. Therefore, children are still very good. Even if they can''t listen to what the old man says, they have to listen carefully.


    The "Yan" tribe has done everything it can do at present. Although the giant indigenous tribes in other areas have no chance to send people to study, they are also developing in the way of "Yan" tribe. Maybe before long, there will be only a few big tribes in the world. Maybe there will be a real tribal war in the future.


    The development of giant indigenous civilization is the limit at this stage. Even if ye Zan does any more guidance and intervention, it will not have much impact on the current situation. After all, yezan has no ability to change the time flow of the world and double the reproduction speed of those giant aborigines. It can be said that the bottleneck of the development of civilization, population, can only be solved slowly by the natural reproduction of giant aborigines.


    Ye Zan, who no longer pays attention to the giant aborigines, is busy transforming their "welfare cave" with Lin''s siblings and casalo. Casalo and others selected their favorite cave design drawings from many models given by Ye Zan. Yezan transformed those mobile fortresses from inside to outside according to their choice.


    "In fact, the appearance of this thing is not very important. The key depends on the internal layout and decoration." Ye Zan, facing a mobile fortress, sent engineering robots to construct according to the drawings while explaining to casalo and others around him.


    Not far away, a mobile fortress like an aerial garden floats in the air of the war fortress. In the sky garden, Lilia, the little demon who has become the God of this world, is flying in and out of the flowers with her own people.


    Lilia waved her magic wand, and the light bloomed among the flowers one after another, making the flowers more colorful and magnificent. With a few obviously different flowers blooming, the newborn goblins in the flower center flapped their wings and flew out.


    The reproduction of goblins is different from that of human beings and most intelligent creatures. There is no process of "intersection of yin and Yang". After all, among the goblins, there are only so-called "women" and no "men". In the words of the technology world, they may be regarded as parthenogenesis.


    In the past, it may be because of "relying on others", Lilia, as the queen of the goblin family, did not give birth to more goblins to strengthen the family. But now, she is already the God of the world. On the other hand, she asked Ye Zan for an air garden, but in fact, the whole world can be regarded as the home of the goblin family.


    Therefore, Lilia finally doesn''t have to worry about the survival of the ethnic group, and can rest assured to devote her energy to the growth of the ethnic group.
