After finishing his cultivation in the early morning of the next day, Zilin took out the remaining three mobile phones, and he kept the No. 2 machine for his own use, and the No. 3 and No. 4 for dismantling and research.

The biggest problem affecting mass production is that the degree of integration of the mobile phone motherboard is too high, and it can be made if it is consistent with the level of refining equipment, but the whole country plus him himself has only six people who can refine the weapon, and the production capacity of six people is facing a market of tens of millions, and the population of Qinglong City in Beijing alone is more than 8 million, which is completely negligible.

Hua Zeguo has a population of nearly 60 million, plus a total of more than 400 million people in other continents, if you want to produce an epoch-making product, you must mass produce it, otherwise it will not affect an era.

To mass production, one must have someone who can produce the motherboard in large quantities, and the other is that there must be a large number of workers who install the motherboard, these people must understand the basic knowledge of the components on the motherboard, as long as one component position is moved, it will cause the whole machine to strike.

The biggest problem of people in this world is that the basic knowledge of communication is zero, and the solution to this problem can only start from the intelligent installation of the motherboard, that is, to create a machine that can produce the motherboard and a robot that replaces the manual assembly of the motherboard.

Therefore, Xia Wan said that he may start the era of communication, which seems to be a simple sentence, but it is actually a huge system project.

He has to build this system from the basics, once the human vision can reach the molecular level, it is simple to make macroscopic things, he only needs to know the principle or deduce the principle to make it, but everything needs time to explore.

He knows very well that this is not a great cause that can be completed by one person, if the conditions allow, he is willing to share the knowledge he has mastered, but he must be a person who loves this knowledge, what he can do at this stage is to build a few more mobile phones, so that interested people can work with him.

Based on the experience he has had, he sketches out specific drawings in his mind and then records them on paper for later people to learn and use.

Then he made a mobile phone, this is the meeting gift he is going to give to Professor Yu, and it is also the key to open the topic of refining, he can't talk about his refining knowledge endlessly when they meet for the first time, that is too superficial, it is better to take a refining achievement that he is most proud of, it is easier to promote the in-depth topic.

After dawn, he sent Xia Wan to morning class, and then left under the envious eyes of his classmates and came to Professor Yu's office.

Professor Yu's office is an independent two-story building, which looks antique on the outside, and when you enter it, you find that there are neat refining materials and stacks of drawings in the two rooms on the first floor.

He met Professor Yu on the second floor, and the two didn't need to be introduced, because he was also a popular figure in the Taoist Academy during this time, and Professor Yu was a well-known beauty refining master in the Taoist Academy.

"Zilin, can you tell us why you chose me as your tutor? It's the first time I've done this kind of work, so I'm curious. Professor Yu asked kindly.

"I'll give you a gift that I made myself, and you'll know why I chose you to be my teacher. As he spoke, he took out his newly made mobile phone and handed it to Professor Yu.

Professor Yu was very surprised, as a one-on-one tutor, he could not accept gifts from students, so he politely refused: "Zilin, the Taoist Academy stipulates that you cannot accept gifts and gifts from students. ”

Zilin didn't expect the Daoist Academy to have this rule, so he thought about it and said, "This is the first homework I have handed in, do you think it's okay?"

Professor Yu didn't reply, took the phone with a smile, and thought to himself, isn't it just a brass block, what kind of gift is this, and it won't be good if the Taoist Academy knows about it.

The shell of this mobile phone is made of brass by Zilin, the motherboard is a jade plate inlaid with spirit stones, and the display screen is a reinforced ordinary crystal, and the appearance is mediocre.

Professor Yu used his divine sense to probe his mobile phone and asked, "Is this a magic weapon?" Look at the formation, it should be a primary magic weapon, although you have arranged hundreds of primary formations in a square inch is very powerful, but it has no attack power, and it is not a threat to ordinary people, what the hell is this? Oh by the way, how can you refine weapons?"

Zilin wanted to laugh, but he couldn't help it, an object beyond the cognitive level of this world can indeed blind the refining master, strictly speaking, the mobile phone is indeed a magic weapon, it is not for attacking, but a machine that transmits and receives signals.

He couldn't help but smile and said, "Professor Yu, this is not a magic weapon, this is a long-distance dialogue instrument that I refined, let me show you how to use it, and you will know the beauty of this instrument." ”

So after explaining the operation process of the mobile phone in detail, Zilin came to the first floor, and then dialed the No. 5 machine in Professor Yu's hand.

After Zilin explained to her, Professor Yu stared intently at the mobile phone screen, and when she heard the sound of "Di Di", she saw the screen light up, showing a line of words "Hello Professor Yu, please connect the mobile phone", she stared at her beautiful eyes in surprise, completely destroying her usual mature and stable image.

With a trembling hand, he pressed the answer button, and Zilin's voice came clearly: "Hello Professor Yu, can you hear me?"

As soon as she was excited, she forgot the method that Zilin taught her, she should put the mobile phone on her ear, she was Jindan in the later stage of the ear hearing is very good, and when she heard Zilin's question, she replied directly to the mobile phone: "I heard it, I heard it, how did you do it?"

"I'll go up and explain it to you in detail. Zilin hung up the phone and went upstairs.

This explanation opened the conversation box between the two people, and Professor Yu asked all the principles and manufacturing processes of the mobile phone like a curious baby, and then the two discussed the application of the formation in real life.

At the end of the conversation, the topic returned to the question of the teacher's inheritance, Zilin just said that the master had ascended without talking about who taught it, Professor Yu pointed to the formation of a Tiangongfang in his mobile phone and said: "Our refining method is likely to come from the same place, Tiangongfang, I am a family heirloom refining method, and someone on my ancestors is a refiner of Tiangongfang, so it has been passed down." ”

"Then we should carry forward the refining method of the Heavenly Workshop. Zilin answered.

"Zilin, do you know why there are so few people in the world who can refine weapons? Why doesn't the Taoist Academy teach the method of refining weapons? It has to be very troublesome to transport the magic weapons that have been refined from heaven to the earth, isn't it more convenient for us to refine them ourselves?" Professor Yu asked several questions in a row.

And these questions are also things that Zilin usually can't figure out, so he shook his head.

"This is the result of the research of several of our professors together, the content involves Heavenly Court, you are my student, I believe you will not spread it, this is because Heavenly Court has set a strategy since five hundred years ago, but it is just a secret, you must ask Heavenly Court why it did this, destroying other people's inheritance, it is because Heavenly Court wants to let the monks of the world have no distractions in their cultivation. ”

Zilin also thought about this answer, but he still couldn't solve the puzzle.

Professor Yu continued: "Take the three members of the royal family who are visiting Zhuo Xing today, their country is the largest country in Zhuo Xing, but they were unable to resist when they resisted the invasion of the Heavenly Demon thirty years ago, and they still have to come to our Blue Star for help, because they do not have a unified command organization on the entire planet, Heavenly Court. ”

"We guess that Heavenly Court should have known that the Heavenly Demons were going to invade five hundred years ago, so it cut off the human Dao system and unified the cultivation of the Nine Realms Chaos Technique, just to form a joint force to defeat the invasion of the Heavenly Demons. ”

"Our enemy is the Heavenly Demon, and now although the Heavenly Demon has retreated, no one is sure when they will make a comeback, so the monks must always work hard to cultivate and not slack off, so there is no room for refining weapons, because refining weapons is a very time-consuming thing, that is to say, everything that can affect cultivation is not supported by Heavenly Court. ”

"I'm telling you this, just to persuade you not to focus on refining weapons, you should focus on cultivation, you are fortunate to be under my door today, and I myself like refining weapons, if you talk to other professors about this topic, they will definitely scold you. ”

Zilin originally thought that he could get her praise and then cooperate in the development of mobile phones, but he didn't expect that she made a big turn in order to persuade him to cultivate.

"Professor Yu, I think people need these convenient things, and they can't just choke on food just because of cultivation. ”

"The mainstream ideology has been formed, so even if people like you and me who know how to refine weapons want to develop this career, it will be extremely difficult, if you insist on going your own way, the result will be that your cultivation will be affected, and the refining career will also be difficult, are you still willing to persevere?"

Zilin replied firmly: "As long as it is helpful to people's lives, and I have the ability, I will definitely persevere, even if the process is very difficult, I will not give up, and my refining does not hinder cultivation, my refining tools have increased my cultivation in the past few days." ”

"By explaining the production process of the mobile phone just now, I know that you are a person with a strong mind, since you are willing to persevere, I will not stop you, but I will urge you in cultivation, otherwise I am afraid of misleading people's children. ”

Although he did not have the support of Professor Yu, he would not give up.
