In the wild world, the Zerg have a kind of meaning of "birds fly in the sky and fish jump in the sea". It is not only because ye Zan liberalized most of the restrictions, but also because of the environment of the world.


    As I said before, everything in this wild world is not simply "year-on-year zoom in". After all, they are real creatures, not arbitrarily zoomed in and out. The seemingly "year-on-year amplification" internally requires many essential factors, such as some special energy or energy substances.


    For the simplest example, giant aborigines are so huge, but their growth rate is no slower than that of "normal people". So, what makes them the same "October pregnancy", and after birth, they can finally grow into giants more than ten feet tall at almost the same speed every day.


    Moreover, not only the giant aborigines, the world, from plants to animals, has a huge body size beyond "normal", but the growth rate is not slower than "normal".


    How much energy does a person need to consume to increase his height by one centimeter? How many kinds of nutrients are needed? Although, some people may say that the babies born to giants are huge, eat more than "normal people" and absorb more nutrition than "normal people".


    However, the reality is not so simple! That is to say, for the size of a giant, if you want to maintain normal activity, you can''t simply enlarge the bones and organs of the body. Their huge size and weight are naturally quite amazing. So can "normal" bones, even if they are magnified ten times, support that weight? Can their organs, only enlarged in volume, maintain blood circulation and nutrient delivery?


    In fact, in the world of science and technology, there have been scientific demonstrations in all directions against the "giant hypothesis". The conclusion of the argument is very boring. It is basically to prove that giants cannot appear on the earth through various theories. At least, with normal human body structure, simple amplification can not survive at all.


    To put it bluntly, it''s not just how many times the size of the bone can be enlarged to support the giant''s body. The density of bones, and even the structure of bones, should also be changed accordingly. Otherwise, these giants, let alone activities, may not even want to stand up. If they move a little, they will break their bones and tendons, and their internal organs will rupture if they lie there.


    So, suppose a bone needs ten times more nutrients to enlarge ten times, and then it needs ten times more substances to increase ten times its bone density. The sum of the two is equal to a giant ten times the size of a normal person. The growth of bones alone needs to consume 20 times the nutrients of a normal person.


    In addition to bones, internal organs, skin and muscles, these are also not only the increase in volume, but also the consumption of nutrients is not only based on volume.


    Therefore, it can be said at least that if a giant is ten times larger than a normal person, it will not only survive by eating ten times the food of a normal person. The same applies to other animals and plants in the wild world, even including bacteria and microorganisms.


    Perhaps, it can be said that everything in this wild world is satisfied with the needs of "greatness", which will create such a huge world. This seems to be nonsense, but it can''t be nonsense, because the Zerg have a strong ability to adapt to the environment, or even use the environment.


    In such a huge world, although Zerg are not indigenous creatures in the world, they rely on their strong ability to adapt to the environment. Naturally, targeted adjustments can be made as soon as possible. Like bigger bugs! After producing a batch of experimental objects that can only be paralyzed on the ground at birth, the Zerg soon had a huge insect soldier who can stand up and fight normally.


    Of course, what really makes more sense for the development of Zerg is that Zerg can use more resources to improve the reproduction speed without "huge" variation. In dealing with extraterrestrial demons, the Zerg''s "gigantization" does not play a great role, but the Zerg sea tactics are more suitable to complete the tasks given by Ye Zan.


    Therefore, under such favorable conditions of resources and environment, the speed of reproduction and expansion of Zerg has also reached a far unimaginable level.


    "Where on earth did these insects come from!" facing the almost endless army of insects, the demons outside the sky roared more than once.


    "Sure enough, it is the will of the world, and only the will of the world can achieve this degree!" the demons outside the sky are more and more convinced that their brains have made up this reason.


    After a period of development, the Zerg at this time are no longer simple harassment, but completely entangle those extraterrestrial demons in place. Regardless of whether they were chasing the giant aborigines or staying on the ground, almost all of them fell into a sea of insects and were difficult to get rid of.


    In the sky, insect clouds blocking the sun hit. Even if several "holes" were blown open by the mobile fortress, they would be filled up by more insects in the twinkling of an eye. The powerful weapon that the demons outside the sky are proud of is a little weak in the face of insects that seem to be unable to kill at all. Although, every shot can still take away thousands of insects. However, compared with the huge swarm of insects, thousands of insects are nothing at all.


    On the ground, the Zerg army is no longer covered by the forest. They saw a group of big bellied beetles pouting their buttocks into the air and spraying acid. Another group of insects covered with rock armor spewed fireballs into the air. There are also some insects with strong hind legs, which suddenly push against the ground and shoot themselves into the sky like shells.


    The mobile fortress besieged by the Zerg looks very embarrassed at this time. The energy defense field is eaten by flying insects, and the armor plate is also corroded. The tianwai demons in the mobile fortress knew that they could not be consumed here, but just wanted to fly away from the fortress, they saw a lot of silk screens flying from all directions.


    "Damn bug!" seeing that the situation is getting more and more troublesome, tianwai evil demons can only ask other companions for help in addition to cursing.


    However, soon, the tianwai demon, who was responsible for contacting other companions, ran to the commander with a frightened face and said: "report, sir, I just received the news that the granite and the iron turtle have been attacked by a large number of insects. I hope we can go to support!"


    "What? Have they met insects too!" the commander was surprised at the speech. Originally, they thought that only they had such an experience. After all, there are many insects in front of them. How can they have spare power to attack elsewhere. But now, hearing the news, he knew that he had underestimated the number of insects and the resistance of the world''s will.


    "In this case, we can only ask the Wizards of other high towers for help!" the tianwai demon, who is similar to the adjutant, suggested to the commander with a complex expression.


    This wild world is one of the "Portals" of extraterrestrial demons, so many forces of extraterrestrial demons have garrison forces here. To put it bluntly, we can''t get all the benefits, and we can''t let all the families carry the risks. It sounds better to work together, but it doesn''t sound better to share the responsibilities.


    However, just like the monastic world, the relationship between various sects may not be good, the forces of demons outside the sky are also close and distant. Therefore, the tianwai demons stationed here usually have little contact with various forces, so as not to cause any contradictions that are difficult to solve.


    Now, when you encounter problems that can''t be solved, you rush to ask others for help. Anyone will have concerns.


    "If you ask for help, the seventh Ring Road and the Third Ring Road are adjacent to us. Who do you think we should ask for help?" the adjutant saw the commander''s intention, so he immediately gave two options.


    "To all the people of the high tower, don''t worry about the past. Now we are facing the same enemy!" the commander was decisive and decided to inform all forces of the situation here without considering other factors.


    "Yes, I''ll do it now!" the adjutant didn''t say much, and quickly prepared to contact other forces.


    However, the demons don''t know these days. While they are ready to ask for help from others, several other forces are also doing the same thing. It is not only this mobile fortress that is harassed and attacked by the Zerg, nor is it just this extraterrestrial evil force.


    Although, with the ability of Zerg and the short development time, it is impossible to really sweep the whole world. However, the Zerg, centered on the site of the three ring tower, is expanding rapidly in all directions like the shock wave of violent explosion.


    Therefore, relying on the territory of the three ring tower, the tianwai evil forces close to the expansion center of the Zerg face the heavy siege of the Zerg. The distant tianwai evil forces were either harassed and entangled by a small group of insect troops, or it was just a matter of time.


    Ye Zan didn''t interfere with the remote communication of extraterrestrial demons, and didn''t mind the combination of extraterrestrial demons these days. After all, the Zerg side has become a "general trend". Those demons outside the sky may not be easily turned over by the Zerg, but it is almost impossible to completely eliminate the Zerg and get rid of the constant harassment of the Zerg.


    Ye Zan, who released the Zerg, was already on the road of saving the giant aborigines with his entourage. On the power territory of the third ring tower, ye Zan destroyed two mobile fortresses, and the remaining ones were scattered in different places. Ye Zan concentrated his superior strength, just like a "bean eater", opened his mouth and walked all the way, eating beans one by one.


    Six Dharma level strongmen, plus a powerful war fortress, are by no means countered by those mobile fortresses. Even if, in the mobile fortress, the tianwai evil devil of the same FA phase level is in charge, it just makes Ye Zan spend a little effort. Basically, ye Zan and his party went all the way. Each mobile fortress didn''t spend much time, and soon completely cleared the area.


    Of course, while fighting against the demons outside the sky, the Lin brothers and sisters did not idle down, but continued to do the work of guiding civilization. They used the same method to guide the rescued giant aborigines, and did not leave the guided giant aborigines behind.


    On the other side of the Fifth Ring tower, the giant aboriginal tribe, which was first guided, has changed greatly from before, although it has only been a few months. They no longer lived in the cave, but built their own wooden and stone houses outside and surrounded the wall with wood and stone. In terms of life, after they learned to roast cooked food with fire, they also learned to burn pottery and cook food with pottery.


    In addition, the old man who was worshipped has been teaching people language and writing these days. Although the use of words has not been clearly reflected in such a short period of time, the communication between giant aborigines has used that standard language. Of course, this standard language is actually the common language in the monastic world.


    "Yan, do you have any good ideas today?" the leader of the tribe asked the boy playing with fire with a kind smile on his face.


    In today''s aboriginal tribe, one of the biggest uses brought by words is to give these giant aborigines names. The boy who played with fire took the name of "inflammation", which is worthy of the name.


    "Not yet. There are still some problems to be solved before firing pottery. I had some inspiration in my dream yesterday and was about to try it." Yan said solemnly, his face no longer as childish as a teenager.


    For giants, firing pottery is not a simple thing, nor can it be solved by "year-on-year amplification". If you burn a bowl ten times the size, if the thickness reaches ten times, it can not be solved by making a fire cellar ten times the size. You should also consider the problem of uniform heating.


    In this regard, ye Zan can give an accurate and applicable answer through calculation and simulation. However, it is not easy for Lin Mu to teach Yan and other teenagers who play with fire through dreams. After all, what Lin Mu is facing here is another problem of the understanding ability of the other party. It is necessary to transform some data and make it easy to understand.


    On the other hand, language and characters are taught according to the cat and draw the tiger, while learning according to the gourd and ladle. It basically does not involve any problems of understanding and practice. It is easier to popularize.


    "Do you want to burn pottery? It''s a good thing. If you can make bigger, it will be very useful to our tribe. In this way, if you need someone, just tell me and I''ll assign someone to help you." the leader immediately patted his chest and promised.


    "Well, I''d better ask Li and man to help me. They have some experience." Yan asked for two helpers without politeness.


    In the outside world, Zerg and tianwai demons have overturned the sky, but these giant aborigines here are slowly developing their civilization as if they were in a paradise.
