Some things, its existence is original sin, such as Zerg.


    In the world of science and technology, the star domain where Zerg relics are found is called the Death Star domain. That is not a simple problem without life. After all, the planets suitable for the birth of life in the universe are quite rare. The reason why we really call it the death star field is that the star field is so barren that life has no meaning to step into it.


    To put it bluntly, in the Death Star domain, everything was swallowed up by the Zerg, not to mention organic things such as animals and plants, even all kinds of metal minerals.


    Of course, Zerg devour all resources and use them for the reproduction and growth of their own group. When they perish, the swallowed resources will naturally be left with the remains. After all, the world of science and technology has the "law of immortality of matter". Even if those metal minerals are swallowed by the Zerg, they will still be left after the Zerg die.


    However, from this point, it can be seen that if the Zerg did not die because of that small accident, it would definitely be a great disaster for the whole universe.


    In this world, or in these extraordinary worlds, the power of the Zerg may be much weaker. However, with the Zerg''s strong evolutionary ability, coupled with its super reproductive ability, I''m afraid the weakness is only temporary. If ye zanzhen let go of the restrictions on the Zerg and let the Zerg have a stable period of accumulation and development, the final result is really hard to say.


    Therefore, ye Zan doesn''t even think about it. He only uses the Zerg for the demons outside the sky. This is a double-edged sword. Once it is out of his control, it will not be just the demons outside the sky.


    "In fact, isn''t it good for you? At least, your race still exists and your blood can continue."


    After ye Zan put away the jade ball, he silently said a word to the Zerg mother emperor, which is more or less persuasive. After all, from the perspective of human reason, treating people who have made great achievements in this way will always make people feel a trace of guilt.


    After returning to the war fortress, the first thing yezan did was to examine the development of those giant aborigines. Their main purpose here is to transfer the civilization of the monastic world here and let those giant aborigines embark on the path of monasticism.


    Speaking of, those giant Aborigines have had a very nourishing life for more than a year.


    Although the Zerg and tianwai demons fought so fiercely in the "front", due to Ye Zan''s special care, the war did not spread to the tribes of the giant aborigines. Therefore, only at the very beginning, when the extraterrestrial demons wanted to implement the genocide plan, led to the destruction of some giant indigenous tribes.


    In the back, after the Zerg suppressed the tianwai demons, the tianwai demons could only defend their stations one by one, so they had no chance to move the giant aborigines again.


    At the beginning, ye Zan gave the giant aborigines "fire" and "language", which should be said to light up the fire of civilization for them. For more than a year, although the giant aborigines did not have the guidance of the Lin family, they did not always stand still with their own wisdom and understanding.


    For example, the giant aborigines used the power of fire to learn how to smelt and make simple metal tools. This metal tool is much better than stone tools, both in life and hunting.


    At first, in order to burn super large pottery for processing food and water, the giant aborigines spent a lot of energy on experimental research.


    But with metal, making metal utensils is much easier. The giant aborigines used "thin" copper plates instead of stone plates to bake food on the stove. The heat conduction effect of the copper plate is much more efficient than the original stone plate, and it is much more convenient and fast to bake food. They also cast huge bronze tripods to cook water and soup instead of fragile pottery. They no longer have to worry about breaking a lot of utensils.


    As for weapons such as knives, axes and arrows made of metal, their performance is countless times better than that of stone tools. The tools polished by stone can''t be too sharp, or they are sharp but easy to damage. However, even the cutting edge of metal tools is easy to blunt, but if they are blunt, they can be polished again. Other tools can be sharp as long as they rub back and forth on the stone.


    In the past, giant aborigines had to cut prey and cut open the fur of prey. Stone tools were simply grinded open a little bit. Now with metal tools, they really have a chance to feel what the word "cutting" feels like.


    Of course, in the development of giant aborigines, more important is about "cultivation".


    Although compared with "normal people", the giant aborigines seem to have a very powerful power due to their huge body shape. But in this world, not only their aborigines, but also those animals and plants are equally huge. In other words, the powerful power of the giant aborigines will not actually stand out in the face of the same huge beasts.


    The "cultivation skill" handed down by Ye Zan to the giant aborigines gives the giant aborigines the opportunity to improve their own strength and the possibility to set foot in "transcendence".


    The first few giant indigenous tribes to receive guidance have now seen many "extraordinary" individuals, making the giant indigenous civilization embark on an extraordinary road. With their extraordinary power, they can more easily obtain prey and deal with various dangers that were difficult to deal with before. This makes other giants yearn more for extraordinary power, and basically lays the foundation for the direction of this civilization.


    In addition, with the improvement of weapons and personal strength, the scope of activities of giant aborigines is becoming larger and larger. When the scope of activities is expanded, they will inevitably have more contact opportunities with other tribes of the same kind. Some of these contacts were friendly and peaceful, but sometimes there were conflicts, so tribal wars emerged.


    It seems to be an instinct that does not need guidance at all to annex other tribes and expand their own tribes. Moreover, perhaps because of the unity of "language", the tribes of giant aborigines don''t have the idea of treating each other as different. As a result, after defeating the other party, they will not kill or even eat everyone of the other party, but have the option of "persuading surrender".


    When yezan paid attention to the giant aborigines again after finishing all things, the giant aborigines in the area once controlled by the five ring tower were about to be completely merged into a large tribe.


    After seeing the development of the giant aborigines, Linmu asked Ye Zan, "brother ye, do you need to guide them to do anything else?"


    "No, they already have enough foundation. The next step is to let them develop slowly." Ye Zan shook his head and said.


    Although Ye Zan and his party came to this world, their main task was to "preach". But nothing can be accomplished overnight, and so can preaching. No matter how much effort Ye Zan made, it was impossible for the giant aborigines to reach the level of the monastic world at once. Let alone the monastic world, it is impossible to catch up with the dawn world.


    However, today''s giant Aborigines have a foundation for cultivation in the aspect of "transcendence", which is tantamount to setting the tone of civilization. They may deviate from this road, but they will go along this direction until they coincide with the monastic civilization.


    "Oh, that''s boring. When shall we go to the inner earth?" after listening to Ye Zan''s answer, Lin Lin seemed a little sorry, or more than enough, and then asked about the inner earth.


    "Wait a minute, the detector is still collecting data!" Ye Zan thought about it here. In order not to make the waiting time too boring, he then said: "during the waiting time, I''m going to transform those mobile fortresses. What kind of fortress you want, you might as well design it yourself."


    At the beginning, ye Zan promised to give casalo several mobile fortresses after eliminating the residual forces of tianwai demons, and help them transform them. Although the promise was made to casalo and others, the Lin brothers and sisters, as ye Zan''s more trusted friends, have no reason, not even casalo''s treatment.


    "I want an aerial garden full of exotic flowers and plants!" Lilia immediately cried when she heard yezan talking about the mobile fortress.


    "Hehe, don''t worry, you''re indispensable!" Ye Zan said with a smile.


    On the issue of moving the fortress, the Lin brothers and sisters were not polite to Ye Zan. Although sister and brother have their own residence in the war fortress, it is not really their own cave after all. Of course, this is not to say that sister and brother are going to leave the war fortress. After all, no one stipulates that a person can only have one residence.


    As for casalo and others, when they heard that ye Zan was going to fulfill his promise, they naturally became excited and began to discuss how to transform their cave very actively.


    "I think intelligent housekeeper is essential. After all, it''s still troublesome for a person to control a mobile fortress."


    "Indeed, although you may find some servants to take some disciples in the future, you can''t give your own cave to others easily."


    "Do you think this is better or more suitable for the array in the cave?"


    "I don''t like that sharp triangle very much. I don''t know if this shape can be changed?"


    Listening to the discussion of casalo and others, ye Zan shook his head reluctantly, then raised the volume and said to the people, "as for the transformation of the mobile fortress, I have some ready-made templates that you can choose at will. In addition, if the selected templates are dissatisfied or have your own ideas, they can also be adjusted through the simulation program."


    Although Casaro and others are strong at the French level, it does not mean that they are good at everything. Let them design by themselves, but describe the cave decoration they want, which is like asking a reckless man to embroider. Although most of them were of noble origin and had certain attainments in art when they were in the small world, they may not be good at "indoor and outdoor decoration".


    Therefore, ye Zan directly asked zhinao to give a large number of transformation models of different styles according to the detailed data of the mobile fortress. This is like a game of simulating construction and decoration. Casaro and others can adjust the increase or decrease in all aspects according to their own needs and preferences on the model.


    Of course, for yezan, there is another great advantage to this, that is, it can avoid Casaro and them from being too wild. As they mentioned, the pyramid shape of the mobile fortress is not good-looking. If you want to transform it into something else, is it different from rebuilding a mobile fortress?


    Maybe, some people will think that it''s just a shell! It doesn''t matter whether it''s square or round, or what strange shape, but what''s the difficulty in changing the shell of the mobile fortress? However, the mobile fortress is not an ordinary building. We should consider not only its shape, but also its practical value.


    For example, some people think that the shape of the Boeing 747 aircraft is not good-looking, so they decide to transform the nose of the aircraft into a shark head, the wing of the aircraft into a butterfly wing, and so on. Finally, you got a wonderful plane in line with your imagination, but can this plane still fly? Even if it can fly, there are still countless problems in this flight, because your transformation of the aircraft shape has a variety of effects.


    Although the mobile fortress is not an aircraft, its shape is not simple. It is only related to the appearance. It must be closely related to other properties. For the simplest example, if the pyramid shape of the mobile fortress is changed, will the original defense system based on it also be transformed? After transforming the defense system, should the energy supply of the defense system also be adjusted?


    Therefore, even though the mobile fortress looks like a rough aircraft, many things in it still move the whole body. After all, this is something that has been used by extraterrestrial demons for tens of thousands of years. In these tens of thousands of years, it has been transformed countless times, and now it has reached the limit of "perfection".


    If a group of laymen look around, they can point fingers at the mobile fortress and put forward one transformation plan or another, the ability of foreign demons was too weak that day.


    "Is there a ready-made model? That''s great. It saves us a lot of trouble!" casalo and others didn''t think too much, but felt that it really saved themselves a lot of thought.


    Therefore, casalo and others immediately connected the fortress intelligence with thousands of miles of inspiration according to Ye Zan''s instructions, and projected one transformation plan about the mobile fortress in front of them. While browsing the transformation schemes, they discussed some problems in the scheme with each other, and tried to make various adjustments on the basis of the scheme.


    "I''ve made up my mind. I want the hanging garden!" Lilia didn''t look at the models, but directly put forward her own requirements to Ye Zan.
