This war fortress of the Outer Demons is not just able to carry the Outer Demons across the space and protect those who lack strength from the power of space. I think that when the ancient immortals and demons were in the war, the outer demons descended in the endless void, and they launched an attack on the cultivation world from the endless void. Therefore, the defense of the War Fortress also has a very strong resistance to threats such as the Void Storm in the Endless Void.

You must know that for the monastic world, the real treasure is not on the ground, but in the endless void. In the endless void, a meteorite may fly by casually, it is a huge spirit stone that can top a spirit vein, or even the whole is a top-grade spirit stone. Another meteorite flying over it may be some kind of precious metal, and any piece of it can be cut off from above, which can make the cultivators in the domain realm crazy.

In fact, everyone knows that the Endless Void is a great treasure, but without the cultivation of the Earth Immortal Realm, entering the Endless Void is no different from sending them to death. Even the Earth Immortal Dao Ancestor had to be extremely cautious in the Endless Void, and it was impossible to treat the Endless Void as his own back garden.

In ancient times, the immortals established the immortal court, from the immortal court heavenly palace to various immortal magic weapons, if they only relied on the resources of the "mortal world", it was impossible to meet that demand. It can be said that the vast majority of the resources consumed to establish the Immortal Court were taken from this almost inexhaustible treasure by the immortals who went deep into the Endless Void.

Ye Zan knew very well that if the Yuqing Sect wanted to develop and one day return to the peak of 10,000 years ago, it was far from enough to rely on the resources in the domain realm. After all, in these 10,000 years, in addition to the depletion of the resources of the domain realm itself, more importantly, due to the decline of the Yuqing Sect, many things that previously belonged to the Yuqing Sect have been divided among other sects.

Those things that have been divided up are in the hands of others, and it is almost impossible to get those things back without using force. No one would want to spit out the cake they've already eaten in their mouth, unless you punch him in the stomach. However, the Yuqing Sect might be able to deal with one or two sects, but could it still be able to deal with ten, eight, or even more sects? In that case, wouldn't the Yuqing Sect become a public enemy of the domain realm!

Therefore, those resources in the domain realm basically don't need to be considered, and if you want to get more resources for development, you must look at the endless void.

Of course, to simply say that flying into the Endless Void, even if there is no war fortress of the Outer Demons, Ye Zan still has the starships of the technological world.

But the problem is that Ye Zan has already done experiments a long time ago, and he still wants to launch a satellite in the Shenhua Domain. However, perhaps it is because of the nature of the power, or because of the influence of some particular law of the world. The defenses of the technological world are as vulnerable as paper in the face of the Void Storm.

As a result, the plan to launch a satellite has been shelved until now, let alone looking for any resources in the Endless Void.

Now, Ye Zan has obtained the War Fortress of the Outer Demons, which means that he finally has the ability to enter the Endless Void, and naturally he will not leave the War Fortress idle.

For a War Fortress to function properly, it needs to have a large number of staff responsible for all aspects of the work, just like the Battlestar in the tech world. In particular, this war fortress does not have a complete artificial intelligence control system, and many things that can be handed over to artificial intelligence still need to be operated by humans.

Of course, after Ye Zan got the war fortress, he replaced the original intelligent master control in the fortress with artificial intelligence in the scientific and technological world, and also transformed the fortress with artificial intelligence control. There is really no way to transform it, and he can also build a robot to take care of those operations instead of personnel.

Therefore, in terms of manipulating the war fortress, Ye Zan does not need the help of others, and it is enough to do it by his own means.

However, a fortress of war, especially in such a world, is not enough to just make it work. In the war fortress, there must be enough strong men to ensure the foolproof of the fortress in the face of various accidents. Otherwise, it is likely that when Yezan invaded the fortress of war, he would be sabotaged by others again.

It was precisely because of this consideration that Ye Zan had an invitation to the Lin family siblings, hoping that the two siblings would become members of the war fortress and help him sit in the war fortress.

"Since Brother Ye trusts us so much, can my sister and brother still say no?" After listening to Ye Zan's explanation, Lin Miaomiao did not hesitate any longer, and nodded very simply.

And Lin Mumu was aroused again, and asked Ye Zan with curiosity: "Brother Ye, are you saying that in the future, when we go to the outer world, we can take this fortress to go over, just like when the evil demons outside the world invaded our domain in the first place?"

"Of course!" Ye Zan nodded, and then added: "It's not just going to the outer world, this fortress's defense ability can resist many threats in the Endless Void, so I'm also going to try to enter the Endless Void for a while." ”

"Wow, go to the Endless Void! That's a place that only Earth Immortal Dao Ancestors can go, and even my Senior Ancestor doesn't dare to go too deep. Hearing Ye Zan's words, Lin Mumu suddenly became even more excited.

After all, just as the people in the world of science and technology yearn for the starry sky, the cultivators of this world also have a similar kind of emotional yearning for the endless void. This is not only because of the resources in the Endless Void, but also because of the adventurous spirit, just as earthlings like to climb all kinds of dangerous peaks.

For Lin Mumu, being able to go to a place where the Master and Ancestor did not dare to go deep was definitely a huge temptation that could not be compared to anything.

"Yes, go to the Endless Void, where it is said to be an inexhaustible treasure in addition to the danger everywhere. If the Yuqing Sect wants to develop, the demand for various resources will increase significantly, and instead of grabbing food on the ground with other sects, it is better to turn its attention to the endless void. It's just that in the endless void, after all, there are too many unknowns, and I'm afraid that it will be foolproof on my own, so I want to ask the two of you to sit in the fortress to help me. Ye Zan didn't hide anything, and directly told his intentions to the Lin family sisters and brothers.

Ye Zan wants the Lin family sisters and brothers to be able to sit in the fortress for a long time, and the two sides will almost be a cooperative relationship, and some things naturally have to be explained first. Otherwise, satisfying curiosity alone is not enough to keep people. After all, Lin Mumu's curiosity about the Endless Void could not exist forever.

"Don't worry, Brother Ye, as long as you can use me, you just have to speak, my Lin Mumu is frowning and he is a puppy!" Lin Mumu patted his chest and said to Ye Zan.

After accepting the invitation, the Lin family sisters and brothers said goodbye to Ye Zan and left Tongtian Peak, said hello to Mo Rushi and the others on the side of Yuqing Sect, and returned to the war fortress. In the war fortress, Ye Zan had already sent a message to the artificial intelligence of the fortress through wireless communication, enhancing the authority of the Lin family sisters and brothers in the fortress. In addition, the Lin family sisters and brothers have also been arranged in the fortress to arrange a quiet room for cultivation.

Regarding the ashram for cultivation, Ye Zan didn't need to rearrange it in the fortress, after all, the demons outside the sky also needed to cultivate and retreat. Therefore, in this fortress of war, there was already a ready-made ashram dedicated to cultivation, which could be used by opening the door directly.

The Lin family's sisters and brothers have already mastered the Dao Realm, and in fact, in terms of their own Dao, they have already met the requirements of the Yuan Shen Realm. It's just that due to the problem of the aura of heaven and earth, and the cultivation time of the sister and brother is slightly shorter, so that the accumulation of their own mana is not enough. For the two sisters and brothers, as long as they can push their own mana to the boundary of the Yuan Shen Realm, it is a matter of course to promote to the Yuan Shen Realm.

And those two Star Spirit Gathering Spirit Pills were originally used by the Tongtian Supreme to replenish mana, and the huge amount of spiritual energy contained in them can be imagined. Originally, with the cultivation of the Lin family's sister and brother Yuan Infant Realm, if they really took this level of Gathering Spirit Pill, even if they would not be blown up in the dantian, ninety percent of their medicinal power would definitely be wasted.

However, the two Star Spirit Gathering Spirit Pills had been kept warm in the white-skinned pill gourd for nearly 10,000 years, and their medicinal properties had already become extremely mild.

Or it can be said that the pill that has not been warmed is like a spoonful of honey, although it is sweet when eaten, but it is only sweet for a while. And the elixir that has been warmed, in addition to being removed from a lot of impurities, is like a hard candy made of honey, and it can't be bitten at all. Just because you can't bite it, you can only use saliva to melt it, and little by little to get the sweet taste from it, it will prolong the time to taste the sweetness.

In other words, these two Star Spirit Gathering Spirit Pills, after such a long period of recuperation, are no longer suitable for supplementing mana. Although, with the cultivation of the Tongtian Supreme, after taking such an elixir, he could also urge the mana to forcibly crush the elixir, but after all, it was still better to dissolve it directly.

The Lin family sisters and brothers returned to the fortress, each entered the quiet room, and then took the Star Spirit Gathering Spirit Pill, which was like holding a hard candy cube that could not be bitten. A trace of aura was "melted down" from the elixir, and with the mana they operated, it continued to gather into the dantian and poured into the body of Yuan Ying.

Of course, this "trace" aura is only relative to the huge aura contained in the elixir itself, and for the Lin family sisters and brothers who are only in the Yuanying realm, they are still as turbulent as a torrent in the meridians. It's just that this turbulence is something they can bear, or even control, and they don't have to worry about causing any damage to the meridians at all.

Besides, on Ye Zan's side, after the Lin family sisters and brothers left, he also returned to the place where Xuanyuan Daozu "retreated", the square in front of the former Yuqing Palace. He didn't take care of the repair work of Tongtian Peak anymore, anyway, those engineering robots and Yuanshen mechanical warriors would automatically act according to the set plan.

Ye Zan chose a place not to be disturbed, and took out the Ice Yuan Crystal Essence that Gou Chen Supreme had gifted.

This Ice Yuan Crystal Essence is a fist-sized blue crystal, and there are bursts of cold air on it, but it is not very cold and piercing in the hand. However, if you don't take the cold of this thing in your eyes because of this, then I'm afraid you will suffer a big loss.

The cold air of this Ice Yuan Crystal Essence is a bit like the so-called "moisturizing things silently", when you really feel the threat of the cold, it is impossible to throw it out. Whether it is your physical body or your primordial spirit, they have been frozen by this cold at this time, and they can no longer do anything, they can only wait for themselves to turn into an ice sculpture from the inside out.

After the Ice Yuan Crystal Essence was taken out, it was almost a blink of an eye, and the area where Ye Zan was was already covered with a layer of frost. Fortunately, Ye Zan had already learned everything about this thing from Gou Chen Supreme, so when he took it, he had already wrapped his palm with wishful thinking.

You must know that the core material used by Ye Zan's wishful thinking is a demonic pearl from the monarch-level yin, which contains the yang qi born from the cathode. Although this Yang Qi may not be comparable to the cold Qi of the Ice Yuan Crystal Marrow, it is still no problem to protect Ye Zan himself from being attacked by the cold Qi.

When he accepted this Ice Yuan Crystal Essence, Ye Zan already had a plan in his heart, how to use the power of this Ice Yuan Crystal Essence, that is, to refine it into the Wishful Change. Perhaps, the reason why Gou Chen Supreme chose to give him this Ice Yuan Crystal Essence was precisely because he had seen him use a magic weapon like Ruyi Change.

Ye Zan let go of his hand at this time, and the Bing Yuan Crystal Essence did not fall to the ground, but floated in the air in front of him, surrounded by a white mist condensed by cold air, as if it was soaring clouds and mist. Of course, this Ice Yuan Crystal Essence has no will, so it is naturally impossible for it to soar through the clouds and mist on its own, so it is just because of Ye Zan's gravity control methods.

Ye Zan, who had freed his hand, pinched the magic trick with both hands, and wishful thinking flew out of his body, hovering around the Ice Yuan Crystal Essence like two silver dragons. In the middle of the circle, some particles that were almost invisible to the naked eye flew out of the bodies of the two silver dragons and landed on the Ice Yuan Crystal Essence. These particles, like nanoworms, began to work on the surface of the ice element pith, just like those engineering robots.

Don't look at the surface of this Ice Yuan Crystal Essence, it looks as smooth as a mirror, but if you change the perspective to the microscopic perspective at the nano level, the smooth surface becomes a pothole. And those wishful nanoworms, in these pits, constantly divide the nano-level particles of the ice element crystal pith, and then integrate them into their own structure.

Originally, Ye Zan's wishful thinking was varied, with the monarch-level evil bead as the core, and due to the power of the sun, it could be called a magic weapon of the sun. Therefore, when using wishful changes and changing other magic weapons, if it is a magic weapon that changes the yin attributes, it does not mean that it cannot be changed, but the power must be affected.

And now, Ye Zan's plan is to add the particles of the Ice Yuan Crystal Essence to the ever-changing particle structure, and form a yin and yang balance with the power of the supreme yang of the Evil Bead.
