Under Yu'er's control, the entire area of the cave sky increased little by little, and at the edge of the cave space where Yi Xuan and Yu'er were originally standing, the outside of the boundary wall was full of tumbling chaotic clouds and mist, and from time to time there were various scenes of the universe flickering in it.

"The outside is the space mezzanine, if ordinary people go in, it is easy to get lost in it, and our cave is built here, so in this universe world, we can open the entrance to the cave wherever you want." While waiting for the cave to slowly expand, Yu'er and Yi Xuan, who were idle, said.

"So, I can open the entrance on my doorstep, or on any planet where I know the coordinates?" Yi Xuan couldn't believe that there was such a power, in this way, he could say that he could go wherever he wanted, and being an airplane or something would simply become a thing of the past, if the era of interstellar navigation came in the future, then he could directly go to any planet that he discovered.

Thinking that he could appear anywhere in the future, so that those syndicate fanatics could cry out in vain, he was very excited when he thought about it, and saw how he cleaned up these guys in the future, Yi Xuan danced while thinking about it.

Yu'er, who was standing next to her, smiled knowingly when she saw Yi Xuan's appearance, because through the psychic connection, he already knew what Yi Xuan was thinking now, which was simply too normal for a person like him who had mastered such a magical function for the first time.

Just when Yi Xuan was excited, the expansion of the entire Cave Heaven Boundary had come to an end, and the newly generated place still showed the most primitive appearance, if the outside of the boundary wall was chaos, the newly generated place was a stable energy composition.

Yi Xuan also saw this newly generated pure energy space for the first time, and he was a little curious to observe it with his spiritual power, and found that the composition in it was the same as that blood-colored knife, without any substance at all, it was a pure string energy ring, which was the most basic energy composition mode.

Yi Xuan realized that the cultivation civilization represented by Yu'er had evolved to a very high level, so it must be from the most basic structure to construct the world.

Looking at Yi Xuan seriously looking at the newly generated space, Yu'er patiently explained: "That's right, this is similar to what you understand, it is the most basic energy string composition, of course, in our cultivation world, we don't call it that, we call him Earth, Water, Wind and Fire, and the chaos outside is the uncontrolled Earth, Water, Wind and Fire, and these newly generated spaces are the stabilized Earth, Water, Wind and Fire." ”

It saw that Yi Xuan was still a little puzzled, so he continued: "This is the name of the relatively high-level of our cultivation world, ordinary monks can only observe the basic elemental composition, but those are already some basic elements of the acquired state, and they are not pure and basic energy, those elemental particles are as big as your atoms, and they are completely different from the most basic energy strings you see now, so not everyone in the cultivation world can use this most basic element." ”

Hearing Yu'er say this, Yi Xuan realized that what he had seen was already a relatively advanced form of the cultivation world, and he thought that the cultivation world was directly applied from such a small basic energy, if that was the case, the cultivation world would be too advanced in the development of the technology world.

"Is that the end of it? But this is different from the newly generated cave space here? Yi Xuan looked at the new space that was completely different from the other cave spaces, and asked a little strangely.

"Of course not, these are just the most basic energy, didn't your scientists have long proposed that matter and energy can be converted into each other? In fact, we also have similar common sense, of course, these can only be used to a certain extent, so I will transform these pure energy spaces into new cave spaces, which will save you from looking strange. ”

Where Yu'er looked, left and right, and finally turned back to Yi Xuan and said, "It's up to you to decide, as the new master of the cave, what kind of space do you want to set up?" ”

Yi Xuan thought about it, this is an important base for himself in the future, and he is even going to move his important scientific research equipment in the future, after all, there are more and more people peeping outside, and entering here will have an extra layer of protection.

So now it can't be shaped according to the model of the Immortal Family's blessed land, Yi Xuan looked at the temple and said, "Yu'er, can you change these temples that have been built?" Or did he build it by a previous owner? ”

Yu'er didn't expect that Yi Xuan first paid attention to the temple, and said with a helpless smile: "Although that temple doesn't have a name on its face now, it is indeed a separate magic weapon, which was refined by the previous generation of masters to facilitate the disciples of the sect to participate in Zen, this will definitely not be moved, if you think he occupies a place, then we will move him to the side." ”

Yi Xuan heard that it was a magic weapon of the previous generation of masters, a magic weapon of such a huge complex, so he had to give up the plan to demolish the temple, after all, he didn't believe in Buddhism, a temple was placed in the cave, no matter how you looked at it, it felt strange, since it couldn't be demolished, then I had to think of other ways.

"Unless you build a high mountain on the edge of the cave, you don't need any roads, and move the entire temple somewhere, so that it won't affect the future construction plan." Yi Xuan finally thought of a compromise.

"Well, in fact, this temple is a very good magic weapon, if you can't cultivate, if you can continue to cultivate, you can refine this magic weapon, you can transform it into the building you want, the function of this magic weapon is quite good." Yu'er said with some pity, but thinking about the current environment, he didn't say more.

In this way, at the edge of this cave, where a new space has just been formed, a towering mountain rises from the ground, and the top is indeed a large flat land, and the entire temple building has been moved by Yu'er as a whole and sits on it.

Because the area of this temple building is too large, it can be said that it is much larger than ordinary temples, so the area of this mountain is also very huge, so when this mountain is formed, you can see this high mountain in the sky when you look up in any place in the cave.

The most interesting thing is that Yi Xuan didn't pay attention to it originally, but now when the temple is moved up, because the mountain is too high, it is not that the eyesight is very good, and the temple on the mountain is basically not visible, but the temple itself is immeasurably shining with golden light, and the mountain is extraordinarily sacred, and it is the residence of the immortal Buddha at a glance.

Yi Xuan didn't expect to cause such a result, he couldn't cry or laugh for a while, he just wanted to move the building away to make room for the future construction plan, but he didn't expect it to create such an effect, I don't know if the people who come in in the future will definitely suspect that this is the land of immortals and Buddhas, and I don't know how to explain it then.

Because Yi Xuan didn't want to spread the things in the cultivation world widely, after all, it was not good for ordinary people to know this information, if those governments and even syndicates knew, it would really be uneasy, and it would be impossible for him to hide in the cave for the rest of his life, and if he went out, all kinds of troublesome people would find him, so Yi Xuan decided not to tell this secret, just that this was a new scientific research achievement of his own.

As for the problem of Shaolin and those martial arts sects, Yi Xuan didn't feel that in the secular world, his Ark Technology Company needed to be afraid of them making trouble, in front of the state machine, these people would only be treated as a group of neurotics or madmen, I believe that no one would believe what they said, after all, they could no longer find an entrance to witness.

Next, Yi Xuan planned the remaining space, because now Yu'er is already an immortal weapon, so the cave can be further expanded, according to Yu'er's conversion according to the current unit, the total area of the cave in the past was 1,000 square kilometers, and now because Yu'er has become an immortal weapon, the ability has increased greatly, and the entire area of the cave has been expanded to 10,000 square kilometers, which has expanded ten times, so big is already larger than most cities. Even the imperial capital is only 16,500 square kilometers, so the area here is already too large.

But because of the relationship between the owner in the past, there were too many mountains and jungles here, and Yi Xuan had major surgery on them with the help of Yu'er.

Basically, most of the mountains were removed, but a circle of mountains was used to distinguish the boundaries on the very edge of the cave, and most of the rest of the places were basically plains, but a few small hills were not high enough to be used for the construction of various residential villas in the future.

Yi Xuan even made a small river running through the middle, of course, the river water here is crystal clear, but there are no fish and shrimp.

All kinds of jungles were also evenly distributed by Yi Xuan over the vast plain, and the number of these trees was not increased.

At first, Yi Xuan wanted to make these trees disappear, but under Yu'er's persuasion, he gave up, and Yi Xuan didn't understand, these trees are very tall, each one is thousands of years old, and they are all now extinct sandalwood, which is the favorite incense raw material of the Buddhas in the past, so they planted a lot in the cave, but now it is difficult to see outside, and it is such a high age, if it were not for the restrictions of the cave, with such a good environment, all kinds of tree spirits would have evolved a long time ago.

But even so, these sandalwood trees are also growing amazingly, knowing that these trees are precious, Yi Xuan, quickly broke off his original idea, and seriously moved them to the surrounding mountains one after another, only a very small part of them were made to a few small hills as trees to reflect the villa in the future.
