The barbarian world is no longer free of extraterrestrial demons, and the giant natives have embarked on the road of developing civilization, and the "preaching" of the barbarian world is on the right track. As far as the current situation is concerned, Ye Zan is "idle" to a certain extent, and he doesn't have to compete against anyone in a "race against time".

Of course, this is not to say that Ye Zan has nothing to do now.

While monitoring the development of the giant's natives, Ye Zan spent the next "leisure" time mainly doing the transformation of the mobile fortress with everyone.

From the hands of the Outer Demons, Ye Zan had harvested a total of nearly fifty Mobile Fortresses, and the combined size was already larger than that of the War Fortress.

Fortunately, Ye Zan has a small world, and he can store all the mobile fortresses in the small world, so he doesn't have to pile them all up outside.

The first mobile fortress to be converted is the Hanging Gardens requested by Lilia.

Although, Lilia's request for renovation seems to be quite exaggerated, almost to change the shape of the mobile fortress.

However, whether the transformation is complicated or not, whether it requires more effort is not completely determined by the external shape.

As the deity of this world, Lilia is not as desperate as others for the most important offensive and defensive functions of the Mobile Fortress.

After all, relying solely on the abilities of the gods, Lilia was already equivalent to the Heavenly Supreme in the savage world.

Therefore, for Lilia, the most important function and use of the Hanging Garden transformed by the Mobile Fortress is probably a garden.

So, according to Lilia's request, Ye Zan quickly completed the transformation of the hanging garden.

In her new home, Lilia gave birth to a new group of her own people through the transplanted colorful spiritual flowers and plants.

Little goblins fly around among the flowers, filling this hanging garden with carefree laughter.

"Let's go in search of the most beautiful flowers in the world!"

After giving birth to a group of goblins, Lilia waved her hand proudly and began her journey to find flowers in the savage world.

Lilia left in the Hanging Garden, while Yezan turned around and began to renovate the Moving Fortress for Casaro and the others.

Compared to Lilia's Hanging Garden, Casaro and the others have a lot more to consider when it comes to moving fortresses.

Casaro and the others are looking forward to moving the fortress in the hope that it can be transformed into a cave of their own.

It sounded like Cassalo and the others' request was no different from Lilia's Hanging Garden.

However, Casaro does not have the power of the gods, nor will they stay in this savage world forever.

In fact, for Lilia, this wild world is her cave, and the hanging garden is at most a small flower bed in the cave.

What Casaro and the others need is not an inconsequential plaything, but a real cave where they can live and live.

Therefore, according to the needs of Casaro and the others, the renovation that needs to be done on this mobile fortress is much more troublesome than Lilia's hanging garden.

A cave house is not just for people.

To put it simply, the cave has to provide people with the capital to "attack and retreat" to a certain extent.

Even in the world, mortals know how to put locks on their homes.

If a cave is just beautiful, like Lilia's hanging garden, but it doesn't even have the ability to stop thieves or robbers, then what's the difference between it and "opening the door and robbering"?

Then again, Lilia's Hanging Gardens are not completely undefended.

It's just that the Hanging Gardens rely not on its own defense system, but on the amount of divine power that Lilia has exerted.

Casaro and the others did not accept the gods of the barbarian world, so naturally they did not have the privilege of Lilia, so they naturally had to find a way to move the fortress itself.

Ye Zan was not stingy, and when Casaro and them renovated the mobile fortress, they even took out the remains of the demons outside the sky.

Of course, most of the remains of the True Immortal-level Extraterrestrial Demon that Ye Zan had been assigned at the beginning had already been used in the war fortress.

However, even a few bone meals, mixed with other materials, are enough to greatly improve the properties of that material.

At the very least, the material mixed with the True Immortal-grade Extraterrestrial Demon Bone Powder was many times stronger than the original material of the Mobile Fortress.

In addition to the material, Ye Zan also provided technical applications in the world of science and technology in the transformation of mobile fortresses.

For example, Ye Zan added a central intelligent control system to their mobile fortress, allowing them to easily and even automatically control the mobile fortress.

This kind of intelligent control system, at least for now, is still very useful for Cassalo and others.

After all, Cassalo and the others are now "alone", and whether they want to accept apprentices or use slaves in the future is a matter of two words.

And the mobile fortress, even if it is not comparable to the war fortress, is not something that can be controlled by one person casually.

What attack system, defense system, flight system, etc., the operation and coordination between various systems is still quite a cumbersome matter.

Not to mention Casaro and the others, even if they are cultivators who have cultivated divine thoughts, it is difficult to control everything in the mobile fortress by relying on the power of one person.

With a central intelligent control system, to put it bluntly, with artificial intelligence, then the owner of the mobile fortress only needs to give instructions, and artificial intelligence can replace people to perform various tasks.

For example, on Ye Zan's own side, the biggest "hero" of the reason why he was able to operate the war fortress was the artificial intelligence in the fortress.

With the assistance of artificial intelligence, Ye Zan can not only control the flight of the War Fortress, but also control the attack and defense system of the War Fortress, and later add a large number of suspended turrets.

You know, each of those suspended turrets is like a small flying machine on its own. Control so many floating turrets, perform all sorts of permutations, and even create a cannon array in formation. If this cumbersome operation is really done by manpower, I am afraid it will only be a disaster.

It must be said that although in terms of the development time of civilization, the world of science and technology is only less than 10,000 years. This time, whether compared to the cultivation world or the world of the outer demons, was so short that it could almost be ignored. However, in less than 10,000 years, the world of science and technology has indeed developed advantages that some of the cultivation worlds and the outer demon worlds do not have.

Of course, in the world of cultivation and the world of the demons outside the sky, there are actually existences similar to artificial intelligence, such as the so-called "machine spirits" in the world of cultivation.

It's just that even if they may have many advantages compared with artificial intelligence in the technology world, they are not something that can be obtained casually.

Let's just say that now, Ye Zan is transforming mobile fortresses for Casaro and others, and each mobile fortress needs to have an intelligent control center, how can it be possible to get so many "machine spirits".

And artificial intelligence, to put it bluntly, is a program that can be copied infinitely, and it can almost be said that it can be copied as much as it wants.

Although, compared to the existence of machine spirits or other intelligences, artificial intelligence in the technological world has no "free will" and appears to be somewhat rigid and lacking in creativity. However, the ability of artificial intelligence is sufficient simply to assist in the control of mobile fortresses, as long as it can strictly follow the instructions given by the master.

In the transformation of the mobile fortress, in addition to increasing artificial intelligence as an intelligent control center, other aspects of supporting it naturally cannot be left behind.

From the attack and defense system, to the power system of the fortress, to the seemingly useless life system, these are all connected to the intelligent control center in order to make artificial intelligence play a role.

On a good note, the technology that Ye Zan uses on the intelligent control center is not exactly a copy of everything in the technological world. Just like the Thousand Miles of God and the like, in order to adapt to the various aspects of this transcendent world, he has also made corresponding improvements to those techniques.

This also means that Ye Zan does not need to replace everything with the product of the technological world when it comes to transforming the mobile fortress.

In addition, regarding the exterior shape of the mobile fortress, it was said before that it cannot be changed at will, but this does not mean that it cannot be changed at all. The main thing is that when doing the renovation design, there needs to be a lot of calculations to simulate to avoid the backfire of the transformation.

And in terms of calculation, Ye Zan naturally has no difficulty here.

As a result, it took about four months for the eight mobile fortresses to finally complete the complete transformation.

Casaro and the other six people of the mobile fortress, basically there is nothing more to say. Although none of them can be compared to the war fortress, they are enough to serve as a cave mansion for a law-level powerhouse.

As for the mobile fortress of the Lin family sisters and brothers, compared with the mobile fortress of Casaro, in addition to being more elaborate on the materials, the important thing is that it also has the function of docking with the war fortress. In other words, the mobile fortress of the siblings can be "combined" with the war fortress, although it will not provide much bonus for the war fortress, but at least they can be dragged together.

After all, even if it wasn't forever, the Lin family sisters and brothers still had to help Ye Zan sit in the fortress of war for a long time. Therefore, even though the siblings had their own mobile fortresses, the main place of life was still on the war fortress of Yezan.

And Casaro and the others, although they don't have a small world like Ye Zan and don't know the "Law Aspect World" of cultivators. However, after all, they are all powerhouses at the peak of the law phase level, and they still have the ability to refine the mobile fortress in a way that is large and small.

After refining it in a way that is as good as it gets, Casaro and the others can completely shrink the mobile fortress to the point that it can be carried around.

After all, the "smallness" of the mobile fortress was only relative to the much larger fortress of war. Since the mobile fortress can be regarded as a cave, it naturally can't really be that small. If you can't put it away and carry it around, then the huge size of the fortress is also quite troublesome when you don't need to move it.

"Brother Ye, this mobile fortress has also been transformed, isn't it time to go to the Inner World next? Lin Mumu asked very eagerly.

In the past four months, although Lin Mumu has also been busy with the renovation project of the mobile fortress, he has not forgotten the inner world in his heart. Basically, during this time, he went to read the information sent back by those probes whenever he had time, and he also learned a lot about the situation in the inner world.

"Well, I've already told Lilia to come back, just wait for her to come back, and I'll be able to open the passage to Inner Earth. "Ye Zan also has a lot of interest in the inner world, otherwise he wouldn't have informed Lilia that she was back early.

After Lilia renovated the Hanging Garden, she went around the world to collect flowers and plants. And Ye Zan also counted the good days when all the work was coming to an end, and told Lilia to come back as soon as possible.

"Alas, that little thing, in terms of exotic flowers and plants, has really learned the greed of human beings thoroughly. Hearing that Lilia would not be able to come back in a few days, Lin Mumu couldn't help but complain helplessly.

After a few days of waiting, Lilia finally returned in the Hanging Garden.

After spending so much time outside, Lilia had collected all the strange flowers and plants of the Savage World, and transplanted them all into her own hanging garden. So much so, when she returned, the appearance of the hanging garden was almost as if it had been completely changed compared to when she set off.

In addition, in addition to collecting a large number of exotic flowers and plants, Lilia also gave birth to a group of her own clansmen in the process. Although there are many goblins among them, they are all bred in the flowers and plants of the savage world, but their body shape has not been affected much, and they still maintain the size of their fingers.

Lilia, who had returned to the war fortress, swung her staff into the air outside the fortress at Yezan's request.

With Lilia's movements, a black spatial passage slowly opened up in mid-air until it expanded enough for a person to pass through.

With the size of Ye Zan and the others, such a large space passage certainly seemed a little narrow. But with Lilia's finger-sized size, this space passage is already quite spacious.

Fortunately, Ye Zan can bring the War Fortress into the small world, otherwise I am afraid that the War Fortress will have to be left here.

"Lilia, you are also a god, why did you open a passage so small! I think that when the demons from outside the sky summoned that octopus monster, they opened a passage the size of a war fortress. Lin Mumu complained quite dissatisfied when he saw the small space passage.

"It's okay to be able to go over, it's very tiring to open such a large space passage!" Lilia replied with an innocent face.

"Alright, I'll put away the war fortress, and we'll have no problem just passing like this. "Ye Zan has already determined that there is no danger on the other side of the passage through the probe that he has placed before, so he doesn't care too much about how to get there.
