Today's war fortress has been renovated by Ye Zan for half a year, although the appearance looks little different from before, but the interior has been turned upside down. Ye Zan basically remodeled the interior of the war fortress according to the interstellar fortress of the technological world, of course, mainly referring to the "work area". As for the outside, the living area located in the upper outer layer of the fortress, Ye Zan still retains some of the style of the world of the Outer Demons.

The energy chamber of the War Fortress has also been converted into an alloy chamber with a special alloy of high strength. After all, this energy room is the top priority, no matter how much you strengthen your defense, it will be too late if someone else invades like Ye Zan did at the beginning.

And not only the energy room, but also the entire working area of the war fortress also has strong defensive measures.

Ye Zan transformed the internal work area into the style of the interstellar fortress of the technological world, not only to look neat and clean, nor to miss anything. His main intention is to replicate some of the defense methods of the Star Fortress, such as making it easier to isolate the invaders. If an intruder is detected by the monitoring equipment scattered throughout the fortress, they will be surrounded by isolation hatches and then subdued by poison or other means.

"Brother Ye, what's the situation, is there anything you want me and my sister to do?" Lin Mumu came to the energy room, and saw Ye Zan standing in front of the energy core and seemed to be in a daze, so he stepped forward and asked with concern.

This time in the "heavens", of course, the Lin family sisters and brothers are also sitting in the fortress, so they also have some understanding of what happened in the endless void.

It's just that the two sisters and brothers can only see superficial phenomena, things like energy consumption, but they can't be as clear as Ye Zan. Even, for Ye Zan's sudden order to return home, the sister and brother didn't know why at first, and originally thought that everything was going well. It wasn't until they came back and saw the damage to the outer armor of the fort that they realized how thrilling it had been.

"Oh, it's nothing, it's just that the previous estimate of energy consumption is a little off, and it looks like it needs to add a little auxiliary energy. Ye Zan came back to his senses, and he didn't hide anything, and told Lin Mumu about his plan.

Lin Mumu scratched his head and said embarrassedly: "In this way, then I can't help with this!"

If there is a fight or something, Lin Mumu can naturally help, but now this kind of technical thing, especially related to the technology of the technological world, is really completely powerless.

"Hehe, don't worry, I can handle it, you can wait for our next departure with peace of mind. Ye Zan said to Lin Mumu with a smile.

"Oh, then I won't bother you, if there's anything I can do to help, just call me. Lin Mumu left such a sentence and turned to leave the energy room.

For the Lin family's sisters and brothers, Ye Zan had naturally given access to all parts of the fortress, even this most important core energy room was no exception. And the Lin family sisters and brothers are also very conscious, knowing what they don't understand, they try not to touch it casually, so Ye Zan has nothing to worry about.

After Lin Mumu left, Ye Zan fell into deep thought again, and it was not just a matter of auxiliary energy. The fuel needed for the cold nuclear reactor is not a rare thing in this world, and with the current situation of him and Yuqingzong, he can also obtain it without any worries. Therefore, for him, auxiliary energy is just a small matter, and it is not too big a question of how much he wants to increase.

However, simply increasing the energy supply is not the best way to strengthen the war fortress, and Ye Zan also needs to consider the efficiency of energy use. Entering the Endless Void this time gave him a very intuitive and clear understanding of the various protective forces of the war fortress. And in the midst of this, he found a big problem, that is, the energy use efficiency of the war fortress seems to be a little low.

In other words, in the Endless Void before, some of the energy consumed by the War Fortress was actually wasted. If that part of the wasted energy can also be put to good use, it will definitely be better than adding too much auxiliary energy.

And what affects the efficiency of energy use, especially what was exposed during this trip to the Endless Void, is naturally the energy protection system of the War Fortress. It has not been tested in practice before, and Ye Zan's protection system for the war fortress only stays at the level of data analysis. It was only after this practice that he really had a comprehensive understanding of the protection system of the war fortress.

With all the knowledge he learned this time, coupled with a large number of calculations and simulations, Ye Zan found a lot of things 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 discovered another auxiliary protection against the Void Storm.

Speaking of this other means of protection against the Void Storm, we have to talk about a thing that Ye Zan has made the greatest efforts to promote and popularize after he came to this world. That's the wireless communication network. Whether it is the previous Qianli Transmission or the Qianli Shensheng in the back, they all rely on wireless communication networks to exist, and even include the online game "Void God Realm".

Due to the advent of wireless communication networks, the space of the Shenhua Domain is now actually filled with invisible "radio waves". This kind of radio wave, although it only transmits various signals, will not cause any real harm to people and other creatures in the same space. However, it is undeniable that the essence of this radio wave is actually a kind of energy, but the energy intensity is lower.

These radio waves filled the space of the Shenhua Domain Realm, and at the same time, they were constantly spreading outside the Domain Boundary, forming a "membrane" that almost no one could perceive in the outer layer of the Domain Boundary. In this case, just like the earth in the world of technology, due to the large use of various electrical devices by humans on the earth, various 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.

On the side of the Shenhua Domain, although the amount of electrical appliances used is not as high as that of the earth, it is only not comparable to the earth in terms of the density of radio waves.

This kind of energy radiation also forms a layer of "energy film" in the near-earth space outside the Shenhua Domain. Originally, this "energy membrane" was really limited in energy, and it was difficult for other people to perceive its existence. It's like people who live on the ground, and very few people actually notice the air in their space. You must know that air is a key substance for sustaining life, and it will be ignored by most people, let alone the radiation of radio waves.

But Ye Zan is different, on the one hand, he comes from the world of science and technology, and on the other hand, he also has the avenue of true knowledge. Therefore, when he entered the Endless Void, he noticed that the outer layer of the domain realm had an extra layer of radiation energy from radio waves. And, on the basis of this discovery, he also discovered that the radiant energy of this layer of radio waves actually had a certain effect on the Void Storm.

In Ye Zan's view, it is a kind of high-energy radiation, just like the cosmic space of the technological world, which is also filled with all kinds of radiation energy that is harmful to the human body. It's just that the Void Storm in this world is more powerful than the harmful radiation in the technological world, and it is extremely harmful to both people and things.

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

Blocking is very simple, as long as you have a strong enough defense means to completely block the penetration of radiation, you can ensure your safety in the radiation. It is like in the world of science and technology, in the early days, lead canisters were used to hold radiation, and 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 study the means of protection in a targeted manner. It's like anti-ultraviolet light, or anti-blue light, which filters out harmful energy radiation through some targeted means.

What Ye Zan discovered was the radio wave radiation layer in the outer layer of the domain boundary, which actually had a certain filtering and weakening effect on the Void Storm.

Although, due to the low energy of the radio-radiating layer, it is not too obvious to play a significant role, and it is the "atmosphere" of the domain that mainly fights against the Void Storm. However, if the strength of this layer of radio wave radiation can be strengthened, and it can be shrouded outside the fortress of war, it will undoubtedly be an effective means of countering the Void Storm.

Although it is said that the large amount of radio radiation produced in the domain boundary has only formed a very small layer of radiation on the outside. But you have to know how big the Shenhua Domain is, and it is not comparable to such a war fortress. If the radio wave radiation layer of the Shenhua Domain Realm was so dense that it was only shrouded in the outer layer of the war fortress, the energy intensity would probably be quite terrifying.

Therefore, while considering adding an auxiliary energy source to the war fortress, Ye Zan also planned to add a protective layer similar to radio wave radiation to this war fortress. According to his calculations, if there was such a layer of protection, it would not require too much energy to be consumed, and it would 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 it. Anyway, he now has no shortage of materials on his hands, nor does he lack a production line for the equipment he needs. They don't need any help from the small world of Asgard, or the production line in the Jade Ball space, and the factory on the war fortress alone is enough to cope with this work.

After receiving Ye Zan's instructions and the manufacturing blueprints of various equipment, the automated factory located in the former commercial area of the war fortress immediately started working on all fronts. 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 this war fortress is not small, so in Ye Zan's calculations, if he wants to achieve the goal he envisions, at least a thousand of these radiation generators will be needed. In order to avoid some non-calculation situations during testing and use, it is necessary to prepare an additional part as a backup.

Production was going on in the factory, and the engineering robots who had been instructed by Ye Zan had already moved the equipment off the production line out of the factory area and went to various locations in the war fortress for installation.

At the same time, although there is an additional means of protection, the energy of the war fortress still needs to be strengthened. Therefore, there is also a part of the engineering robots, around the core energy room of the fortress, some of the surrounding cabins have been transformed into auxiliary energy rooms. Anyway, the war fortress in Ye Zan's hands now no longer needs to leave too much space to carry a large number of people like the demons outside the sky. Therefore, this war fortress, in fact, still has a lot of free space, and there is no problem in transforming it into an auxiliary energy room.

Of course, the transformation of the war fortress is not as simple as installing things. Since the auxiliary energy source has been added, and so many radio wave radiation generators have been 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, so such a big project can be easily handled. In just a few days, another renovation 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 of a role it can play, still needs to be tested in practice.

After the renovation work was completed, Ye Zan notified the Lin family sisters and brothers, and ordered the war fortress to rise again.

The huge war fortress slowly left the "flat roof" where it was docked, and the four legs at the bottom closed into the original square cone, and then continued to climb towards the sky. It didn't take long for the Tongtian Peak, known as the Tongtian Peak, to completely fall below the war fortress, and quickly shrank in people's sight until it disappeared.

"Enter the Gangqi Layer!"

In the main control room of the War Fortress, the 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?" Lin Mumu asked Ye Zan with an expectant face. The last time he entered the Endless Void, the War Fortress only stopped for a moment, and before he could see the scene in the Void clearly, he quickly returned to the interior of the Domain. He didn't know exactly what was going on, he just felt that the last time was too unpleasant, and at this time, he was naturally full of expectations for the second time to enter the void.

"Well, if there are no surprises, there should be no problem. However, even then, you can only watch from the inside of this fortress, and I haven't found a way to enter the Endless Void. In the face of Lin Mumu's inquiry, Ye Zan nodded, but said half-jokingly.
