There is a stone door in the small stone cave, and on the stone door, there is a pattern of 8864 hexagrams that is slowly rotating regularly.

Hua Lanting tried to pull the door knocker with his hand, but the stone door opened with a touch, and the two walked in.

There's a cave inside, it's a tiny world.

The environment is lush trees, birds singing and flowers, animals in the mountains, swallows in the forest, and stone tables, stone benches, stone beds and other daily necessities.

The two of them came here from the boring and monotonous array, and they suddenly felt refreshed, like entering a fairyland.

There wasn't much space, and they walked around it after a short time, and they didn't find any exercises or secret magic weapons or anything like that, but the two of them didn't care.

Because, they found that the refreshment was not just due to the environment, but that the aura here was unprecedentedly rich, and the breath was comfortable from the inside out, and the spiritual power in the body seemed to be a little stronger.

This is simply a blessed place that cultivators dream of.

There is only one strange thing, there is no sky like the outside world here, not far overhead, there is a crystal bright cyan light curtain that cannot be seen through, although there are light and dark changes, there is no sun, moon and stars.

Upon closer inspection, the two were stunned.

There seem to be water ripples on the light curtain, and there are many translucent water droplets hanging, which occasionally fall but do not fall, but disappear halfway.

Oh my God. That's a liquid aura!

The spirit stones of each grade in Xianzhou are only the difference in size and density concentration, although there is a division in quantity caused by the compression ratio, but the spiritual energy in them is all gaseous, and there is not much difference in nature.

This liquid form, which I have never heard of before, not only does every drop contain a huge amount of aura, but the quality of the aura is extremely pure, and it is a great supplement for the cultivation of holy products.

Faced with this scene, Hua Lanting was not calm, and wanted to go up and touch it every inch of a thousand miles.

But the cyan canopy is obviously not high, and there is no obstruction in the middle, but it is unreachable no matter what.

After trying many times, the two swallowed their saliva unwillingly, so they had to dispel their thoughts first.

That's okay, the aura on the ground is abundant enough. The machine spirit clone no longer appeared, and the two of them were happy to be quiet and greedily cultivated on the spot.

There are mountains and rivers, birds and beasts here, and their eating and drinking are no longer a problem, and after making sure that there are no other outlets, Hua Lanting and Yue Guanghan meditate and breathe with peace of mind.

This is a long, long time.

According to the change in the sky, it is estimated that it will take nearly two years.

The two of them had nothing to do, cultivating day and night, and their cultivation improved by leaps and bounds.

As the days go by, I always think about the outside world, and my mentality becomes impetuous.

During this period, they also looked for a way out and called for the machine spirit many times, but to no avail, and the sound transmission technique was as ineffective as in the big array, could it be that it was to wait until a time limit, or break through to a certain realm to be completed?

Now, Hua Lanting and Yue Guanghan have reached the peak stage of the Five Qi Dynasty Yuan and the Four Elephants Yin and Yang Realm respectively, and the two of them keep in mind the teachings of the sect, and before breaking through to the next great realm, they would rather accumulate the limit than improve easily, waiting for the last moment that cannot be suppressed.

Moreover, when the two were learning the technique, Hua Lanting accidentally found that he could actually recite Yue Guanghan's spell to launch the Great Piercing Technique, which was an unexpected gain.

In between cultivation, the two of them were reluctant to let the aura here go to waste, and used their means to create a large number of artificial spirit stones, which they could use when they went out one day.

On this day, I was really depressed in one place for a long time, and I always had to find something new to do, so Hua Lanting began to think about the way to touch the liquid aura from heaven again.

Suddenly, finally, the voice of the long-disappeared machine spirit clone reappeared: "It's useless, the spatial dimension above is different from this. ”

Hua Lanting and Yue Guanghan had already spoken nothing between them, often not saying a word for a few days, and when they heard the sound of the machine spirit, they just asked someone to chat, so Hua Lanting asked: "How can you not see or touch it when you are in the same place?"

"I've heard that space is multi-dimensional, and in addition to the three dimensions of length, width and height, there is also a fourth-dimensional time, is it because there is an invisible barrier and the speed of time is different, so I can't go up?

The machine spirit said, "I don't know very well about this. Regarding the spatial dimension, ancient and modern figures are still inconclusive after exploration, and each has its own theory. The old ancestor of this space created it when he was in his prime, and I think he will have a new understanding later, but even so, this secret realm is not something I can speculate about. ”

"The zero dimension is a point, the one dimension is a line, the two dimensions are a surface, the three dimensions are a body, the fourth dimension has a time axis, the five dimensions of a time plane, the six dimensions of a time body, and I don't know more than seven dimensions. ”

"A two-dimensional space is an arrangement of straight lines, a collection of countless one-dimensional spaces. Three-dimensional space is the arrangement of countless two-dimensional space faces. By analogy, the four-dimensional space should be an infinite number of three-dimensional spaces arranged in the dimension of time, and it is unimaginable that there are more than five dimensions. ”

"There is a saying that if you are in the five-dimensional space, you can see all the things that happen in the one-two-three-four dimensions, such as all your countless past, present, and future reincarnations, including the process from birth to death, whether you are a human, an animal, or some other form. ”

"But you don't have the right to change it directly, because any parallel two, four-dimensional, three-dimensional space is difficult to traverse, unless it's extremely fast or you can break through the barrier between the two. ”

"According to my current understanding, time may exist in the fourth dimension, the fifth dimension, or any kind of dimension, and it is not within the conventional dimension, but it does not exist, and it is an abstract concept that is not real. ”

"When we look at the length and width of the two-dimensional world, the two-dimensional world is stationary, and we are in motion. From this inference, the creatures in the four-dimensional space see us as stationary, while people are in motion. ”

"The lower planes of the same dimension can be traversed, but if they cross dimensions, it is unknown what each extra dimension is. Even if it is only one dimension, it is a world that we cannot imagine and reach. ”

Hua Lanting was indeed puzzled, and frowned: "Some people say that the universe is born of yin and yang, its big is not outside, its small is not inside, all dimensions of space are in it, including all things and things in the past, present and future, and any space plane will collide, and the energy generated will affect each other, cross and overlap, and have a reversible ******* Ling thought for a while: "Maybe what you said makes sense, but this influence and the secret of reversibility have not yet been fully grasped." In my guess, since the art of prediction can foresee the future, it must be connected to the time dimension that runs through all the space-time interfaces. And this kind of common method, from the known, may be hidden in the easy to learn. ”

Hua Lanting would not let go of any opportunity to learn, and asked, "About Yi, have you taught me anything?"

Ji Ling said: "You can discuss one or two, easy to learn and profound, I will teach a little, and the rest depends on you to explore slowly." ”

"When you entered, there were sixty-four hexagrams on the door, do you know the origin?"

Hua Lanting said while pondering: "To put it simply, the four elephants of yin and yang form eight trigrams, the earliest ones are Tianqian, Dikun, Shuikan, Huoli, Lei Zhen, Fengxun, Shangen, and Zedui, each of which corresponds to a three-painting hexagram. ”

"The three painting hexagrams, there is heaven above, there is earth below, and all things are born in the middle, among which people are the spirits of all things, and the three painting hexagrams are the three talents of heaven, earth and man. One is yang, two is yin, and three is change. ”

"After that, heaven, earth and people have yin and yang, so the three painting hexagrams become six painting hexagrams, and six is two threes, so it is called a double hexagram. From this, it continued to evolve into the image of the sixty-four hexagrams. ”

"Good. The spirit continued: "Each hexagram is six paintings. Thousands of tall buildings rise from the ground, the earth is one and two, the sky is five and six, and the people represent three and four. ”

"The sky has yin and yang, the earth has rigidity and softness, and people have benevolence and righteousness. Therefore, between heaven and earth, only people will be unkind and unjust. ”

"Huh?" Hua Lanting and Yue Guang said coldly, so that's the case?

"Haha, just kidding, knock you guys. Your knowledge and skill are constantly improving, but without righteousness, it will be very terrible and dangerous. ”

The machine spirit turned to say: "The three painting hexagrams represent the three talents of heaven, earth and man. Among them, the sky is changing, and the celestial phenomena are changing all the time; the earth is not easy, the earth does not change often, and a change is an earthquake and tsunami; and people are transactions, also known as simplicity or simplicity. These are the three meanings of Yi. ”

"First of all, as the name suggests, simple is simple. ”

"It's like the chopsticks you eat on the stone table over there. Two chopsticks, one yin and one yang, together are Tai Chi. So that the chopsticks are often one does not move and the other moves, the two are matched, and the food reaches the mouth. ”

"Simple, right. If you can clamp it, you can clamp it, if you can't clamp it, you can dial it, and all problems are solved, how can it be so complicated. I heard that other continents used knives and forks to eat, and they occupied their hands, which was both complicated and inefficient. ”

"For example, a soft brush, you can write thicker, you can write thinner, you can write, you can paint, the structure is very simple, but the function of change is infinite. ”

"This is simple, but next, what about the changes and difficulties of heaven and earth? To put it bluntly, it is change and change. ”

"The Book of Changes was first called the Book of Changes. The way of yin and yang, there must be change and permanence, yang is change, yin is constant, combined together, relative and inseparable. ”

"Tao Te Ching" has a cloud at the beginning: Tao can be Tao, very Tao. There is an unspeakable common way in the world, and what can be said is an extraordinary way. ”

"What does not change is the ontology, substance, and principle, and what changes is the phenomenon, appearance, and illusion. ”

"What does not change is the cosmic avenue, which represents the state of absolute perfection, freedom, equality, and light. Everything is changing, and the universe is always that universe. But to be born as a human being and to be a living being can only attain relative perfection, freedom, equality, and light, because all living beings have desires and destructiveness. ”

"Change and immutability are inseparable. If there is no change, where will there be no change? If everything does not change, there can be no change. ”

"Have you changed? You said that you haven't changed now, but your qi and blood are flowing, your physical body is being renewed, and you can't live if you don't change. ”

"Is time changing? But can your childhood be changed? Can your ancestral home be changed? If you can't change, the past will be gone. The future is unpredictable, but what about the present?

"The biggest test in life is now. Because: some change, some do not change. Variable can be unchanging, and it can be unchanging. There is change in the unchanged, and there is no change in the variant. Change is also dead, and change is also dead. ”

"Things are not people, but the country is still the same. The world is like chess, but at this moment, you have food at noon, a bed to sleep in at night, and the sun rises in the east and sets in the west, and you can't change it. ”

"So, when you think of change, you must think of change. When you think of change, you have to think of change. ”

"When the moon is full, we know it's about to start to die. When people seek perfection, they actually can't get along with themselves, but they must live to be perfect. ”

"Confucius said that the method is from the top to the middle. It means that people must have ideals, not give up, do their best to do it, and then listen to the destiny of God. ”

"Good and evil are also like yin and yang, but pure good can't tolerate yourself, pure evil others can't tolerate you, and it will also change. ”

Hua Lanting was confused when he heard this, and interjected: "You don't say that I understand a little, but I am confused when you say this." How do you grasp that?"

The machine spirit said, "It's rare to be confused. What is confused is the surface, and what is understood is the heart. ”

"We must change from an unchanged standpoint, so that we will not change randomly. ”、

"The principle is that the right does not deviate from the scriptures, and the right does not use much. ”

"Power is a change, and it is a regular rule, a rule that will not change often. Principled change is called strain, and unprincipled change is called chaotic change. Sticking to principles is annoying if you don't know how to be flexible, and changing around without principles is equally annoying. It is important to become reasonable and in line with the situation at the time. ”

"The principles can also change, but if they change often, the original rules are problematic and immature. ”

"There are exceptions to everything, but it is not right that there are more exceptions, and it is reasonable to do this often and occasionally like that. ”

"Lao Ziyun: I don't know the usual, I act recklessly, I don't know the routine, I blindly change randomly, I lose my roots, and I am fierce. ”

"Alright, it's time for you to leave, goodbye. ”

Hua Lanting and Yue Guanghan were still experiencing the aftertaste, and the words of the machine spirit clone stopped abruptly, and they immediately issued an eviction order, and no matter how much they shouted, there was no response.

The two were dumbfounded, and Hua Lanting thought about it: "He won't come to the old man for no reason." Since it is about change and immutability, it is necessary to leave, and the unchanging routine should be to walk out of the door in a serious manner. ”

Yue Guanghan said, "We've tried." The hob meat is the same, it can't be pushed away, it can't be broken, and it can't be broken when it hits. ”

The two came to the stone gate again, and Yue Guanghan tried again to no avail.

Hua Lanting was distracted for a moment, and said to himself: "Change and change, what does not change is to go to the door, and what changes is ......"

Stretching out his hand, there was no knocker on this side, and he gently clasped the crack in the door and pulled it.

The door opened.

Is this simplicity?

When they came in, the door was open to the outside, so they subconsciously always agreed that if they wanted to go out, they had to push the door open outward, and who knew that it would become......

The two were speechless.

Yue Guanghan was anxious, and when he took one step, he exclaimed, his person disappeared, and the stone door immediately closed automatically with a clang.

Hua Lanting was stunned, hurriedly opened the door again, and took a look.

Below is a cliff of 100 zhang, the mountain wind is howling, and the stone cave when it does not return.

Moreover, the scenery outside is very different from that of Shuxuan Immortal Continent!

What is this place?

As far as the eye could see, there was no figure of Yue Guanghan, it was impossible for a big living person to disappear so completely so quickly.

Turning around, the stone gate could no longer be opened.

The voice of the machine spirit appeared again: "He has another chance, and he will return to the Vientiane Gate safely." This journey, you can go on your own. ”

The cliff couldn't overwhelm Hua Lanting, so he pulled the vines and vines, and slipped off the cliff and fell to the ground.
