Today''s war fortress has been transformed by Ye Zan for half a year. Although its appearance looks little different from that before, its interior has changed like earth shaking. Ye Zan''s transformation of the interior of the war fortress is basically based on the starfortress of the scientific and technological world. Of course, it mainly refers to the "working area". As for the living area outside, located in the outer layer of the upper part of the fortress, ye Zan still retains some styles of the world of heavenly demons.


    The energy room of the war fortress was also transformed into a cabin wrapped in alloy, and special alloy with high strength was used. After all, the energy room is the top priority, and it''s not too much to strengthen the defense. If someone invades like Ye Zan, it''s too late to regret that the defense is not enough.


    Moreover, there are strong defense measures not only in the energy room, but also in the working area of the whole war fortress.


    Ye Zan transformed the internal work area into the style of starfortress in the world of science and technology, not only to look neat and clean, but also not to miss anything. His main intention is to copy some defense methods of starfortress, such as isolating intruders more conveniently. Once an intruder is found by monitoring equipment all over the interior of the fort, it will be surrounded by isolation hatch after hatch, and then it will be poisoned or subdued by some other means.


    "Brother ye, what''s the situation? Is there anything for me and my sister to do?" Lin Limu came to the energy room and saw Ye Zan standing in front of the energy core as if in a daze. He came forward and asked with great concern.


    This time, the Lin brothers and sisters were also sitting in the fortress, so they knew something about their encounter in the endless void.


    However, sister and brother can only see superficial phenomena, such as energy consumption, but they can''t be as clear as ye Zan. Even for ye Zan''s sudden order to return, the sister and brother didn''t know why at first. They thought everything was going well. They didn''t know how dangerous it was until they came back and saw the damage to the outer armor of the fort.


    "Oh, nothing, but there is some deviation in the previous estimation of energy consumption, and it seems that it needs to add auxiliary energy." Ye Zan returned to his mind without any concealment and told Lin Mu his plan.


    The wood scratched his head and said, "well, I can''t help you!"


    If you fight or something, trees and trees can naturally help, but now this technical thing, especially related to the technology in the world of science and technology, is really powerless.


    "Hehe, don''t worry. I can handle it. Just wait for us to start next time." Ye Zan said to Lin Limu with a smile.


    "Oh, then I won''t bother you. If there''s anything I can help, remember to call me." Lin Mumu left such a sentence and turned away from the energy room.


    For the Lin brothers and sisters, ye Zan naturally has long given access to all parts of the fort, including the most important core energy room. The Lin brothers and sisters are also very conscious. If they know what they don''t understand, they try not to touch it casually. Therefore, ye Zan has nothing to worry about.


    After the trees left, ye Zan fell into meditation again, not just for the purpose of auxiliary energy. The fuel needed for the cold nuclear reactor is not very rare in this world, and he and yuqingzong can obtain it without worry. Therefore, for him, auxiliary energy is just a small thing, and how much he wants to increase is not a big problem.


    However, simply increasing the energy supply is not the best way to enhance the war fortress. Yezan also needs to consider the energy use efficiency. This time he entered the endless void, which gave him a very intuitive and clear understanding of the various protective forces of the war fortress. Among them, he found a big problem, that is, the energy efficiency of the war fortress seems to be a little low.


    In other words, some of the energy consumed by the war fortress in the endless void was wasted. If that part of the wasted energy can also be well used, it will be better than adding too much auxiliary energy.


    What affects the efficiency of energy use, especially what is exposed in this endless trip to the void, is naturally the energy protection system of the war fortress. Before that, ye Zan''s protection system for the war fortress has not been actually tested, and it just stays at the level of data analysis. It was not until this practice that he really had a comprehensive understanding of the protection system of war fortress.


    With what he learned this time and a large number of calculation and simulation, ye Zan found many places worth improving in the protection system of the war fortress. At the same time, in addition to the original protection system of the war fortress, he also found another auxiliary protection means for void storm.


    When it comes to this other means of protection against void storms, we have to say that ye Zan has made the greatest efforts to promote and popularize after he came to the world. That is the wireless communication network. Whether it is Qianli sound transmission before or Qianli spirit transmission behind, it all depends on the wireless communication network, and even includes the online game "virtual divine world".


    Due to the emergence of wireless communication network, the space of Shenhua domain is actually full of invisible "radio waves". Although this kind of radio wave only transmits various signals, it will not cause any substantial harm to people and other creatures in the same space. However, it is undeniable that the essence of radio waves is also a kind of energy, but the energy intensity is low.


    These radio waves filled the space of Shenhua domain boundary, but also continued to spread outside the domain boundary, and formed a "membrane" in the outer layer of the domain boundary that almost no one could detect. In this case, just like the earth in the world of science and technology, due to the extensive use of various electric equipment by human beings on the earth, a variety of radio waves are emitted. A large number of radio waves, affected by the earth''s magnetic field, form an invisible barrier in the earth''s near earth space.


    Although the Shenhua domain does not use as much electrical appliances as the earth, it is just that it can not compare with the earth in the density of radio waves.


    Such energy radiation also forms an "energy film" in the near earth space outside the Shenhua domain. Originally, this "energy film" has limited energy. It is difficult for others to detect its existence. For example, few people living on the ground will really notice the air in their own space. You know, air is the key material to maintain life and will be ignored by most people, not to mention the radiation of radio waves.


    But ye Zan is different. On the one hand, he comes from the world of science and technology, on the other hand, he also has the avenue of true knowledge. Therefore, when entering the endless void, he noticed that there was an extra layer of radio wave radiation energy in the outer layer of the domain boundary. Moreover, on the basis of this discovery, he also found that the radiation energy of this layer of radio waves had a certain impact on the void storm.


    What is a void storm? In Ye Zan''s view, it is a kind of high-energy radiation, just like the space in the world of science and technology, which is also full of all kinds of radiation energy harmful to human body. However, the void storm in this world is more severe than those harmful radiation in the world of science and technology, which is extremely harmful to people and things.


    There are roughly two directions for how to eliminate radiation hazards, one is the well-known barrier, and the other is targeted neutralization.


    Blocking is very simple. As long as you have strong enough defense means to completely block the penetration of radiation, you can ensure your safety in radiation. Just like in the world of science and technology, in the early days, lead cans were used to contain radiation. Later, with the development of science and technology, there were radiation protective clothing of various materials.


    The neutralization method requires a certain understanding of radiation. At least you have to know its wave particle properties, and then you can develop targeted protection measures. This is like anti ultraviolet or anti blue light, filtering out harmful energy radiation through some targeted means.


    Yezan found that the radio wave radiation layer in the outer layer of the domain boundary has a certain filtering and weakening effect on the void storm.


    Although, because the energy of radio wave radiation layer is still very low, it can not play a too obvious role. It is mainly the "atmosphere" of the domain against void storms. However, if we can strengthen the intensity of this radio wave radiation layer and cover it outside the war fortress, it will undoubtedly be an effective means to combat the void storm.


    Although so much radio radiation is produced in the domain, only a very small radiation layer is formed outside. But you have to know how big the Shenhua domain is. It is not comparable to such a war fortress. If the radio wave radiation layer of Shenhua domain is so thick that it is only shrouded in the outer layer of the war fortress, I''m afraid the energy intensity is quite terrible.


    Therefore, while considering adding auxiliary energy sources to the war fortress, yezan also plans to add a protective layer similar to radio wave radiation on the war fortress. According to his calculation, if we can have such a protective layer without consuming too much energy, it will be enough for the war fortress to cope with the ordinary void storm safely.


    Through the calculation of the auxiliary chip, ye Zan quickly built a specific model in his mind and immediately began to manufacture and equip. Anyway, he now has no shortage of materials and production lines for manufacturing the required equipment. We don''t need any help from the fairy palace small world or the production line in the jade ball space. The factory on the war fortress alone is enough to cope with this work.


    After receiving yezan''s instructions and the manufacturing blueprints of various equipment, the automatic chemical plant located in the original commercial area of the war fortress immediately began to work and get busy. In less than ten minutes, the first radio wave radiation generator was sent down from the factory''s production line, followed by the second and third


    The size of the war fortress is not small, so in yezan''s calculation, if you want to achieve the goal you envision, you need at least thousands of such radiation generators. In order to avoid some situations other than calculation in the process of testing and use, another part needs to be prepared for standby.


    The factory continues to produce, and the engineering machines instructed by yezan have moved the equipment off the production line out of the factory area and went to various locations of the war fortress for installation.


    At the same time, although there is an additional means of protection, the energy of war fortress still needs to be strengthened. Therefore, some engineering robots have transformed some of the surrounding cabins into auxiliary energy rooms around the core energy room of the fortress. Anyway, the war fortress in yezan''s hands now doesn''t need to leave too much space to carry a large number of people like the devil outside the sky. Therefore, there is still a lot of free space in this war fortress. There is no problem in transforming it into an auxiliary energy room.


    Of course, the transformation of war fortresses is not simply a matter of putting things together. Since auxiliary energy is added and so many radio wave radiation generators are added, the energy path naturally needs to be transformed.


    Fortunately, ye Zan has the help of artificial intelligence and a large number of Engineering robots to do things. Such a big project can be handled easily. In a few days, another transformation of the war fortress was completed under the "supervision" of Ye Zan, and a series of commissioning work was carried out. However, whether it really works and how much it can play still need actual testing.


    After the reconstruction work was completed, ye Zan informed the Lin brothers and sisters and ordered the war fortress to take off again.


    The huge war fortress slowly left the docked "flat top", the four feet at the bottom closed into the original square cone shape, and then continued to climb upward. It didn''t take long for the so-called Tongtian peak to fall completely below the war fortress and shrink rapidly in people''s sight until it disappeared.


    "Enter the vigorous gas layer!"


    In the main control room of the war fortress, artificial intelligence constantly reports the height of the fortress and automatically adjusts the operation of the fortress.


    "Brother ye, is there no problem this time?" linlimu asked Ye Zan with expectation. The last time he entered the endless void, the war fortress just stopped for a while. Before he could see the scene in the void, he quickly returned to the interior of the domain. He didn''t know what had happened. He just felt that the last time was too boring. At this time, he was naturally full of expectations for entering the void for the second time.


    "Well, if there is no accident, there should be no problem. However, even so, you can only watch in this fortress. I haven''t found a way to let you enter the endless void." facing the query of trees, ye Zan nodded, but said half jokingly.
