With Ye Zan''s cultivation, it''s a dream to refine magic tools by yourself. Moreover, even if he could practice, he didn''t want to spend his time on such things. So he decided to find a "OEM", and Qi Qianjun is undoubtedly suitable for this role.

    What Qi Qianjun refined can''t be regarded as a magic weapon. Simple materials and simple runes have almost no attack and defense power. No one will know what those things are for until they are finally assembled.

    Qi Qianjun is indeed a responsible "OEM" and has no slightest neglect of what ye Zan has explained. It took two days and two nights to refine everything Ye Zan needed.

    In yezan''s plan, the future communication network will be spread to the whole Shenhua domain. At that time, the required communicators and information transmission base stations will be a very large number. With Qi Qianjun''s refining efficiency, of course, this demand can not be met. Finally, we have to rely on industrial production.

    However, now everything is still in the experimental stage. We can''t start industrial production until various specifications are determined. Moreover, when ye Zan did these experiments, the brain had actually started the research of industrial production.

    To refine magic tools, you need to use mana to depict runes. This carving is not carved with a carving knife, but affects the molecular arrangement on the surface of the material through mana, makes it form runes, and resonates with some force in the world. If we want to complete this process with industrialization, many problems need to be solved, but they are not insoluble.

    After ye Zan got those parts, he immediately began to assemble them, just like a jigsaw puzzle. Because of their particularity, these parts should be called modules, and each module has its unique function.

    Soon, an information transmission base station was assembled by Ye Zan. The base station is not very big. At the top is a circular signal transceiver, and at the bottom is a cylindrical shape. The interior is the core of information processing. The signal receiving and forwarding range of this base station is only 50 km radius, which is more than a little worse than scientific and technological equipment, which has reached the performance of some original base station in the earth era.

    Then, it is the so-called "mobile phone".

    Considering the difficulty of Qi Qianjun''s refining, the modules of mobile phones are relatively large, so that when combined, they are like the original "big brother" in the history of mobile phones. However, after all, it is used for experiment. Beauty is not considered, as long as it can be used.

    Moreover, the main function of the mobile phone is to dial up and send and receive messages, without redundant functions such as photo games. What ye Zan needs now is to solve the communication problem first. As for turning this into a portable intelligent device, it will be in the future.

    Ye Zan assembled three mobile phones, immediately went to Wu Changsheng and Jin Dasheng, and sent one to each of them.

    "Your Majesty, what is this?" Wu Changsheng took a brick like mobile phone and looked over and over again, but he still couldn''t understand the use of this thing. It seems that it should be a magic weapon, but it''s not suitable. It looks like fragments of magic weapons.

    "Alas, I''ve said it many times. Even if there is no outsider, don''t always call me that. It''s strange for you, an old man, to call me this young talent." Ye Zan joked, then raised his mobile phone and introduced them: "You can call this thing a thousand miles away. Although it can''t be that far now, it''s still OK within three or four hundred miles."

    "Thousands of the miles?" Jin Dasheng took it and listened in his ear, but he didn''t hear anything.

    "That''s wrong. Do you see the number button on the top? My number for thousands of miles is six one. Press the green one after you press it." Ye Zan seems to teach children how to use mobile phones.

    Jin Dasheng pressed the "one" key six times in a row on his mobile phone, and then pressed the green button. In less than a second, a strange sound of music came from the mobile phone in Ye Zan''s hand.

    Ye Zan connected the phone and stopped Wu Jin''s follow while walking outside the hall.

    Jin Dasheng imitated Ye Zan''s appearance and put his mobile phone next to his face. Sure enough, he heard Ye Zan''s clear voice in the "thousands of miles of sound".

    The voice was not small. Wu Changsheng nearby could hear it. But when he raised his mobile phone, he didn''t hear anything. When he learned from Jin Dasheng and pressed the green button after dialing on his mobile phone, he heard a female voice "sorry, the number you dialed is in the middle of a call, please redial later."

    Looking at Jin Dasheng, who is chatting with Ye Zan on his mobile phone, Wu Changsheng really feels a little scratched. He simply stepped forward, took Jin Dasheng''s mobile phone and said to Ye Zan, who can''t see: "martial uncle, I''m Wu Changsheng. Why did I just do like younger martial brother Jin, but a woman talk to me?"

    "Because I''m talking to Lao Jin now. Now there''s no function of multi person communication. I can only talk one-to-one. Wait a minute. I''ll hang up here and you can dial again."

    Ye Zan''s voice came from his mobile phone, and as he finished speaking, a beep came.

    "Eh, why not, martial uncle? Martial uncle?" Jin Dasheng shouted to his mobile phone, looked up at Wu Changsheng and asked, "what does it mean to hang up?"

    After some experiments, Wu Changsheng and Jin Dasheng both knew how to use mobile phones and their usefulness. It''s really convenient. You don''t need to send someone to find it or send a book with a flying sword. You can talk to people hundreds of miles away by dialing a few numbers here.

    Of course, they also know that this communication is still limited, at least for now. For example, the current signal can not be completely covered by the whole yuqingzong. To solve this problem, either improve the "base station" or increase the number of "base stations". If you leave yuqingzong, this thing will lose its function, unless at any time the whole Shenhua domain is full of things called "base stations".

    "In fact, you don''t have to worry about this. If people know the convenience of using it, they will naturally ask us to build a base station in their home." Ye Zan is full of confidence in the promotion of mobile phones.

    "However, in my current position as jade emperor qingzong, I''m afraid..." Wu Changsheng said with some worry. Although the words didn''t finish, everyone could understand, just afraid of being robbed by others.

    Indeed, if the mobile phone is popularized in Shenhua domain and welcomed by countless people, it will also become an extremely attractive huge cake. A third rate sect like yuqingzong holds such a huge wealth. It is like a child walking in a busy market with money, but it may lead to disaster.
