At the moment when he had just taken a step, Lin Xuan inadvertently separated himself from Don Na - he was inside the worm 'hole' and Don Na was outside the worm 'hole', separated by the transparent air, but it was no longer possible to converge.

"Lin Xuan! Lin Xuan! Donna shouted.

Lin Xuan lowered his head and looked at Don Na's forearm. Under the squeeze of an invisible force, the muscle 'flesh' on the forearm is being tightened. If it continues, the power will surely squeeze Donna's forearm off.

"Okay." Lin Xuan sighed and let go gently, and Don Na's arm 'twitched' back helplessly.

Suddenly, Lin Xuan's ears quieted down, although he saw Tang Na calling with his own eyes, he couldn't hear any sound.

He read the other party's 'lip' language, and then replied in 'lip' language: "Don't worry, wait for the worm 'hole' to open again."

That being said, the appearance of the worm 'hole' has a great 'nature', and the worm 'hole' they encounter at this time is obviously different from the previous and future ones, and the place to reach the other side of the worm 'hole' is also uncertain. Therefore, the worm 'hole' that opens again will not send the two to the same place, but will go in opposite directions.

Donna replied in a 'lip' voice: "Wait for me, wait for me, don't go far!"

Out of the corner of Lin Xuan's eye, he caught a glimpse that the tumbling 'waves' had stopped moving, and it seemed that the worm 'hole' was disappearing.

"Lin Xuan, live well, live well at any time, we will be able to meet." Donna told him in the 'lip' language.

Lin Xuan's heart sank, he had heard too many words like this, and they had become the standard signal of life and death.

There is a layer of colorless transparent barrier between the two, which is extremely thin, but extremely hard, and cannot be broken or penetrated.

Lin Xuan looked behind Tang Na, and the world suddenly became strange.

It is true that he and Don Na all the way were on the flat land of that world, and the specific location was almost 10,000 meters from the top of Mount Everest in the Himalayas. He is familiar with that world, because human beings are born in that world. But this time, he found that the world was becoming stranger.

Maybe the qiē he sees in his eyes has not changed, but in his consciousness, it seems to be a vague world that is not real, and it is fundamentally different from the world in his memory and impression.

It was a strange feeling, and it scared him: "Is that the world I've lived in?" Why is it so strange and doesn't have any intimacy?"

It is clearly stated in the philosophical texts that the free world, that is, the natural world, is the objective natural basis of human practical activities. It includes the natural world before the creation of man, that is, the natural world that has not yet penetrated into the world and the activities of the descendants of human beings, that is, the natural world that has not yet been humanized. The human world, also known as the human world, refers to the unity of nature and human society that man has transformed.

People transform the world according to their own ideology, and in some inaccessible places, the world still retains its original appearance, and the difference is like the second-hand house in the real estate market and the 'rough' house.

The free world and the human world are opposites and unified, and practice is the basis for the differentiation and unity of the free world and the human world. This argument includes three levels of relations: first, the world of freedom and the world of human beings are interactive. In the practical activities of man, the world of freedom is constantly transformed into the human world. The process of "humanization" of nature is also the process of the formation and development of human society. Second, in the practical activities of human beings, the human world is constantly changing the free world, making natural nature become humanized nature, and the free world and the human world are differentiated and unified on the basis of practice. Third, nature and society in the human world are mutually restrictive and interpenetrate, becoming the nature of society and the natural society. Nature in the human world is the nature that has been branded by society, and it is the nature of society. Society, on the other hand, is a natural society in which people themselves practice the process of material exchange and energy conversion with nature.

There are generally two erroneous tendencies in human beings in understanding the relationship between the world of freedom and the world of human beings: one is that people do nothing in the face of the powerful world of freedom; The second is the excessive humanization of nature, which has changed various natural processes and caused ecological differences. Both of these mistakes will have serious consequences for the development of human society.

Lin Xuan's retelling of this astringent and esoteric theory was to force himself to regain his senses, to stay sober, and not to be angry and resentful of Heaven and nature because he was separated from Don Na.

At this moment, in his opinion, the space in which Donna is located is like a primitive world that has not been destroyed by human social behavior, and it is completely different from the earth in the 21st century. This is very strange, because humans have been present on the earth for thousands of years, and more than seventy percent of the land has left traces of human transformation. A person's blood must flow with the special factor of hometown, no matter how long it takes, no matter how far it goes, there is a deep imprint on the body, and eternal life cannot be changed.

If a person feels unfamiliar with their hometown and has doubts, it can only prove that it is not their hometown.

"Not hometown? And where?" Lin Xuan smiled bitterly.

He stared at Donna's back for a long time, and every inch of land became strange and strange as far as the eye could see. In the end, he even felt that Donna was not the beautiful Russian 'girl' he had met by the ghost lake before, but a completely different person.

"Donna, you-" He spoke, but his lips stopped halfway through, for he had no idea what he was about to say, what he could say.

"Let's go." Donna said in a 'lip' language.

"Wait until I'll get back." Lin Xuan replied in the 'lip' language.

He immediately smiled bitterly and said to himself: "Can I still go back?" If it's not my hometown, why should I go back?"

When he lowered his head and pondered, Donna couldn't see his 'lips', and the two couldn't use ''lips'. [,！ ] slang "'crossed' flowed.

A study by Baylor College of Medicine in Houston and City College of New York in the United States has shown that visual information can help people recognize more language words they hear, especially at certain noise levels, which can be up to six times higher. With the help of vision, the human brain can obtain certain visual information from the movement of the speaker's face and lips, which can help the listener better identify the content of the speech, and the movement information of the face and the lips can help the listener improve the recognition rate of about 10 to 60 under different noise levels.

The two of them couldn't 'communicate' with their eyes, and the effect of the 'lip' language was greatly reduced.

Lin Xuan couldn't understand what this layer of transparent glass separating the two of them was, it shouldn't be something produced by the humans of the earth.

From a physical point of view, glass is neither crystalline, nor amorphous, nor polycrystalline, nor is it a 'mixed' state. The theoretical name is glassy. The characteristics of the glass state at room temperature are: short-range ordering, that is, in the range of several or dozens of atoms, the atoms are arranged in an orderly manner, showing crystal characteristics; Long-range disorder, that is, after increasing the number of atoms, it becomes a disordered arrangement, and its 'mixed' and 'chaotic' processes are similar to liquids. On a macroscopic level, glass is again a solid substance.

So, who made this glassy thing?--42041+dsuaahh+25541747-&&
