After a war between the two ancestors, the valley became a mess, including the other four residences, and all buildings had collapsed. It seems that the small pool in the valley has not been affected at all. It must be the prohibition of the secret place.

    Although the disciples of Yuqing didn''t make much effort, they all looked tired after such a stimulating night, especially disturbed by the fierce ghost. However, in their eyes, they still show the color of yearning, yearning for a higher realm and stronger power.

    As for the left behind disciples of Sizong, you don''t have to look at them. Maybe they were killed by those dark shadows when the ghost owl Taoist first arrived. But in this way, this is not the business of yuqingzong family. After all, there are foundation building disciples among the disciples left behind by each sect.

    Mo Ru swept his mind and knew that no one had survived the four sects, so he took out four paper cranes, wrote information and threw it into the air. The four paper cranes, like living beings, turned in mid air, flapped their wings and flew in all directions, and soon disappeared.

    Seeing this scene, ye Zan couldn''t help touching his chin. Although the paper crane looks very magical, it may be much less practical than the communication technology of science and technology.

    There are many ways of communication in this world, but just like the communication technology in the world of science and technology, there is really no such convenient and fast.

    In the secular world, we still use the way of express horse in the post station. At most, we can make a flying pigeon to deliver books. Both efficiency and security are appalling. Although the practice world is better than the secular world. There are paper cranes, flying swords and jade talismans, they also have their own problems.

    Paper cranes are commonly used by practitioners. Although they are not slow, they can not reach instant messaging. Moreover, if you want to talk more, you can only fold paper cranes back and forth by two people. To pass a book by flying sword, to put it bluntly, is to deliver the book by flying sword, which is often used by acquaintances. If the relationship is not very good, the flying sword will have the meaning of provocative demonstration.

    As for the jade talisman of communication, the speed of communication is the fastest, but it is also the least used by practitioners. The reason is very simple. When you send a message, you have to crush a set of jade symbols. You have to agree in advance what message to send. For example, when it is agreed that the jade talisman will be crushed there, when it is found that its own jade talisman is broken, it will know that the situation in the agreement has occurred there.

    In the view of people in the world of science and technology, although the principle may be mysterious, the effect is like a joke.

    However, does the communication technology in the world of science and technology crush these communication methods?

    In fact, it can not be said to be so absolute. If only from the effect, it may be that scientific and technological communication is instant and efficient. However, it is not so easy for sci-tech communication to do this. For users, the communication parties simply press a few keys, but behind this, they need a lot of cost investment to realize this simplicity.

    Not to mention the wisdom of predecessors, countless people have paid these, just in the process of communication. The relay station required for signal transmission, whether it is a satellite in the sky or a base station network on the ground, does not need a lot of cost investment to build. With the development of the world of science and technology to the interstellar era, the information transmission between star regions requires more construction and maintenance costs.

    In this world, not to mention the primitive means of communication in the secular world, let''s say these three common ways in the spiritual world. Regardless of the effect and the difficulty of use, at least this is the business of the two communicators. There are costs that the communicators pay, such as mana.

    Therefore, the problem comes. If ye Zan wants to promote scientific and technological communication in the world, one problem he can''t get around is signal transfer.

    When they were in the secret territory, the communicator used by Yuqing disciples was limited by transmission distance. However, the secret place is so large that the area set aside for Yuqing sect is smaller. It is impossible for Yuqing disciples to leave each other too far.

    What about the so-called Shenhua realm? Its area is unimaginable, and its vertical and horizontal length is more than ten thousand miles, which can almost be compared with the solar system in the world of science and technology. In such a huge world, it is impossible for communication to go through transit.

    There are two ways of signal transfer, transmitting satellites or building ground base stations. It seems that the cost of launching a satellite is lower, but it is directly lost by Ye Zan. The sky in this world is much more terrible than the sky in the world of science and technology.

    The sky outside the world is called endless void, but although it is void, it does not mean there is really nothing. It is said that in the endless void, there is a void storm at three or five o''clock. All kinds of Gangsha Qi are mixed together, and the earth immortals will lose half their lives if they fall inside. Still want to launch a satellite? I''m afraid it will be blown away in less than a day.

    Therefore, the ground base station is more reliable.

    Ye Zan is not whimsical, but really wants to make it happen. In a small way, yuqingzong has convenient communication with each other, and in a large way, he may be able to establish a communication company that monopolizes the world. Of course, the communication company will consider it for a long time. Even now, it can''t be held by the strength of yuqingzong.

    In this regard, ye Zan has learned a lesson. In the world of science and technology, if the family were not so eager for quick success and instant benefits, it might not be the result of introducing heterogeneous storage technology early.

    Ye Zan was thinking about the plan and seemed a little silent for a moment. Seeing this, Mo Ru thought that the supreme martial uncle was frightened. After all, ye Zan''s seniority is no matter how old he is. Not everyone can be indifferent after such an experience.

    "Younger martial brother," Mo Rushi came to Ye Zan and cried out with some worry.

    "Ah?" yezan returns to his senses and turns to look aside.

    "Your Majesty, it''s all our negligence that surprised your majesty." Mo rushes to apologize in a voice that only Ye Zan can hear.

    Ye Zan doesn''t get used to it for a while. Usually, Lao Mo shouts, and doesn''t regard Mo Ru as an elder than himself. But at this moment, seeing Mo Ru''s worry on his face, ye Zan thought of his father, even though it was dog blood.

    When I came to this world alone, the families and blood relatives on the other side of the technology world were gone. Don''t think just because you don''t dare to think, but can you really put aside everything and live in this world heartlessly?

    "Too superior?" Mo Ru shouted again.

    Ye Zan shook his head and seemed to want to throw out what he had just thought. Then he smiled and said, "it''s all right. I''m not good! Lao Mo, you''re really good at that skill just now. Don''t tell me about the magic weapon. What skill does your move emit a lot of light? When can I learn it?"
