Seeing that the content he saw was less than one-tenth, Yi Xuan suddenly felt as if he had eaten enough, and nothing in his mind could be engraved with more content for the time being.

The rest of the content was like through hard glass, and Yi Xuan couldn't see it no matter what.

"Okay, don't bother, the rest of the content is now based on your knowledge, if you rashly see it, it will easily cause the collapse of your worldview, which is not conducive to your continued cultivation, so this memory space automatically blocks these contents, and when you cultivate in the future, you will naturally be able to see it." Yu'er saw Yi Xuan's unrelenting appearance, and hurriedly persuaded him.

"Are you saying that I will be able to see it when I come up in the future? Isn't it like the rules of the world just now that won't let me see it? Yi Xuan was a little skeptical and said, the matter of the "Mixed Yuan Heart Sutra" just now hit him quite hard.

But if you think about it carefully, it's not right, because doesn't it mean that you can't cultivate? If you can't cultivate, how can you improve your cultivation, then don't you still see these contents?

Faced with Yi Xuan's question, Yu'er was helpless for a while, and told Yi Xuan that you can continue to watch the content just now, which has a way to explain how to continue walking.

It turned out that Yi Xuan had only seen a part, and in that huge Taiji circle, there were words like notes explaining different locations.

Yi Xuan hurriedly found a note in the Yin Side part, and only looked at the development of the Yin World that was written on it.

It turns out that the underworld universe is not like the end that everyone understands, only waiting for destruction, and the life inside it can find a new way out through its own evolution.

There is also a branch here, which is the connection of the composition of world civilizations, which has a more detailed explanation of the evolution of life, Yi Xuan carefully examined it step by step, and finally let him know how to save his world.

It turns out that the evolution of life in the world is generally divided into micro-evolution and macro-evolution, of course, these are all interpreted according to Yi Xuan's own knowledge, because the text annotations formed here are actually formed according to Yi Xuan's knowledge, so Yi Xuan feels that these annotations are not very accurate.

For example, this microscopic civilization is a bit similar to the current direction of civilization progress on the earth, which is to develop how to understand the world through the application of the basic physical properties of matter, establish many disciplines based on this, develop systematically, and finally gradually understand the world from the perspective of gradually understanding these microscopic particles, and then transform the world by using these microscopic particles.

And now the vast majority of the scientific and technological progress of the civilization on the earth is actually continuing to develop in the microscopic direction, and the most representative of them is the theoretical physics that Yi Xuan is very good at.

At present, human beings on the earth have even advanced theoretical physics to a very difficult point, so that many physical theories cannot be verified by existing scientific experiments, and can only exist in hypotheses.

Not long ago, before Yi Xuan came to participate in the Bon Festival, he also heard that the United States had proved an important property of gravitons through scientific experiments: the existence of gravitational waves, and since then, mankind has begun to explore the development of gravitational applications on a larger scale.

At that time, the life individuals of the microcosm civilization will further evolve from the outside to the inside, the life form will be sublimated, and finally it will evolve into an existence like immortals, so that the universe in which they are located can naturally be saved, but if the means of external cognition of the world cannot be developed to the point of using or even creating, then basically the world will also enter a bottleneck, or even destruction.

In Yu'er's memory space, the microcosm civilization is gradually developing in this direction, but the development of the microcosm civilization is similar to the current development of earth science and technology, and the development of the macroscopic civilization of another civilization is very similar to the cultivation development that should appear on the earth in ancient times as Yi Xuan understood.

Macro civilization is generally born in the period when the rules of the world are very perfect, basically this civilization is born in the yang side of the world in the Taiji circle, so it is easier for the life in it to feel the existence of the rules of the world, and it is also very easy to use these rules to promote the progress of civilization.

And this kind of progress is more from the direction of individual evolution, so macro civilization is also known as individual civilization, because in the genes of life, the pursuit of eternity is deep in the bones, since the individual life can explore the rules of the world to strengthen itself, basically these lives will not develop like the micro civilization of the systematic study of foreign objects to develop.

However, because this kind of individual civilization is extremely dependent on the natural environment, when the world gradually enters the yin side of Taiji, basically if it cannot be transformed into a microscopic civilization in time, the world will generally go to extinction.

Through these, Yi Xuan gradually understood that according to some ancient legends, to the current development of civilization, the cosmic world in which the earth is located is undergoing the transformation from a macro civilization to a micro civilization.

That is to say, the earth has undergone a process of shifting from the yang side of Tai Chi to the yin side of Tai Chi, and now there are basically no traces of cultivation on the earth, even if the martial arts cultivation of Yi Xuan and others is more like a way to strengthen themselves, it has not risen to the level of cultivation, and even sometimes Yi Xuan feels that the cultivation of martial arts should be more scientific and systematic.

Since the earth is already on the road of micro-civilization evolution of scientific and technological development, but it is about to face the end of the world as Yu'er and others say, so it is too late to say that the transformation of the earth's civilization evolution mode has come? Is there no remedy?

Although Yi Xuan saw this, he knew why the earth had entered the end of the world, but it seemed that there was not much time left, could this cosmic world really be hopeless?

"Do you think this universe exists on Earth? Just before the cave was closed, I knew that in this cosmic world, there are countless different kinds of civilizations, so many years have passed, there must be civilizations that are ahead of the evolution of microscopic civilizations, and the earth is only an inconspicuous one among countless civilizations, but until I wake up again, I still haven't seen the slightest change from the rules of the world, and this cosmic world is still moving towards the road of the end of the world. Yu'er said regretfully to Yi Xuan.

"This is strange, since you said that there are so many advanced civilizations, why can't we earthlings find these alien civilizations until now?" Yi Xuan asked strangely: "Wait, it's not that I can't find it, but there is already a civilization among us." ”

"Oh? There are other civilizations that have come to your earth, so you just said you couldn't find them? Yu'er asked, although Yu'er could see Yi Xuan's thoughts, it was impossible for him to see Yi Xuan's entire memory.

Yi Xuan finally explained to him that the syndicate organization he had encountered after gaining spiritual power was already the black cat, which meant that they were an alien civilization that had never appeared in everyone's field of vision.

When Yu'er heard Yi Xuan say this, her expression suddenly became difficult, and she said to Yi Xuan: "It seems that if we want to break through the last tribulation, it is really very difficult!" ”

Hearing Yu'er say this, Yi Xuan was puzzled, how could he hear himself talk about the situation of the syndicate, he would say this.

"You have to be mentally prepared, it seems that the cosmic world where the earth is located has been targeted by the demon world, according to what you said, there must be a lord of the demon world who is laying out this cosmic world, and the syndicate organization you encountered may only be the tip of the iceberg." Yu'er's words were very heavy, at first he wanted to see how to help Yi Xuan achieve a short-term leap in the level of civilization on the earth, but he didn't expect that the cosmic world in which the earth was located had begun to be in danger.

"The Demon Realm? Are you talking about the Demon Realm where the Demon Emperor you suppressed is located? Yi Xuan asked strangely, because according to what he had always understood, the Syndicate might be a colonist of an alien civilization since ancient times, and those so-called Egyptian gods were the code names of that alien civilization, but he didn't expect it to be connected to the Demon Realm.

"I ask you, has this syndicate never made an official appearance in your world, but is bent on controlling the most powerful empires in every time period, and they will continue to carry out some assassination activities?" Yu'er asked, and these were exactly the things that Yi Xuan learned about the syndicate through Li Junjie.

"That's it, how do you know?" Yi Xuan asked strangely.

"This is not surprising, because the Demon Realm is a world dedicated to destroying the world and obtaining resources from it, so all the Yin Worlds that are going to be destroyed will generally have their existence." Yu'er explained.

"Isn't the Demon Realm the world on the Taiji Circle?" Yi Xuan didn't expect this demon realm to be so special.

"Of course, according to your knowledge, the demon world is the world in another dimension, that dimension is completely different from the dimension of the Taiji Yuan you are in, and they are indeed the public enemies of all worlds, because the meaning of their existence is to destroy, and to make progress from destruction, so those demons will use various means, such as the temptation or charm of various desires that point directly to the heart of life, the catharsis of fear, the amplification of despair, and the termination is to let the world go to destruction." The more Yu'er spoke, the more serious she became.

"The syndicate?" Yi Xuan asked.

"That's right, the syndicate should be an organization sent by an advanced alien civilization controlled by the demon world, and their ultimate task is to prevent or interfere with other civilizations from developing something that changes the world, because this method of preferring to kill by mistake and never let go may completely cut off the world's self-salvation, and finally achieve the result that those demons want."

Hearing Yu'er say this, she suddenly remembered her experience after gaining spiritual power, no wonder it was like this.
