Renault regrets it now. The shaking phone is just a toy that he is bored and wants to reflect his own value. Yes, it is just a toy.

Because Renault knew very well that with current technological level, the phone he made was not much more skillful than the earpieces his children played with.

Do you know the earpiece? A very simple little thing, two paper cups, drill holes at the bottom, connect them with a metal wire, and then you can speak to each other and hear the other person's voice. Of course, the distance cannot be too far, such as twenty meters, or closer.

The effect of a shaker phone is naturally much better than that of a receiver. After all, it uses electrical energy and resistance to convert sound waves into electric shocks, and then converts them from electric shocks to sound waves. The loss in this process will also be very large, so its noise and alternating sound will be so loud that it is unbearable.

Renault thought so, but others didn't think so. Bai Jing and Fire arrived half an hour later, and there was nothing about Renault next. Renault felt that the two excited secret masters needed the most now, and if they continued to be so excited, it would easily cause heart problems.

The excitement was not only the two secret masters, but also the students Renault had brought to play with, but also turned into science madmen, following behind the two secret masters, and they had to try it if they had the chance.

Usually, the two secret masters could drive them all out of the temple, but this is Renault's Temple of Divine Works, so they tried their best to restrain their dissatisfaction and occupy two phones as much as possible.

Mo Zi was anxious to scratch his head, but he had the lowest status here and didn't even have a chance to get close. Murphy was very calm and never approached. He looked at him from a distance, and his eyes were envious.

This thin boy had a delicate heart. Seeing that he didn't have the chance to get started, he put his ideas on the box in Zhangtan, which had a lot of parts in it.

Mozi ran back and forth, looked at the phone with the open internal structure, then went back and forth to see the parts in the box, and ran back and forth for more than a dozen times to confirm that he had basically understood.

But this is not enough. The things belong to you. He is just a cat and a dog adopted by you. Even he himself thinks that the animals in the Temple of God are more noble than him. For example, the purple shadow who is crazy about people, and two big birds who have begun to practice flying.

Renault had long seen that Mozi was pretty good, a very smart young man, just like a little bit cramped: "I want to try it?"

Anyway, Reno sat in a corner of the study and asked softly, drinking tea.

"Your Excellency...I..." Mo Zi was at a loss and didn't know how to answer. In his more than ten years of life experience, the first thing he learned was the high and low.

"Then try it." Renault didn't care about these things. If the people around him were like him in the future, they would be as timid as he did, and could not even say a complete sentence. It would be too boring.

"I...can I?" Mo Zi's courage was even smaller than Renault imagined.

"Go to do it boldly. It's nothing. You should know that these things are all created by Zhangtan. Even if they are broken, they can still be created." Renault said with a smile. Cultivation games are usually quite fun.

But, it seems a bit wrong. People are all working on luoli, but why did they become the master of their own?

Renault admitted that Mozi's name was too deceptive, which made him involuntarily want to cultivate fake Mozi with real Mozi.

In fact, he knew that this was impossible. Mo Zi on Earth could be worshipped for thousands of years, not what he knew, but what he invented when no one could.

Even if Mozi can learn everything he knows and carry forward it, he is just an excellent student and cannot be compared with Mozi in history.

Mo Zi stretched out his trembling little hand and took out the parts from the box, assembling them while recalling them. Renault fell into deep thought again.

The names of the people of Da Chu are so interesting.

Luo Yi, a hero in the late Sui Dynasty and early Tang Dynasty, had a strong army called the Eighteen Cavalry of Yanyun.

Renault's history is very average and has a popular level. The names of people he can remember are very famous in history.

Zhu Chongjiu, this name is even more interesting. If you remember correctly, Zhu Yuanzhang, the founding emperor of the Ming Dynasty, was nicknamed Zhu Chongba. Is this Lao Zhu's younger brother?

Li Si, the prime minister of the Qin Dynasty, although he is a little transparent in the Shengong Hall, he is actually a serious master of 800 people. Such people have only more than 30 people in the Saint-Jingluo City, a population of more than one million.

Finally, it’s Mozi, this name is Giant Niu.

In fact, besides these people, Renault was most curious about the names of the two secret masters, Bai Jing and Fire, which sounded ordinary, but he felt that these two surnames seemed to have some connection, and Renault had not figured it out yet.

Mozi had a pair of flexible hands and a smart head. It took him half an hour to assemble two shaking phones.

Two copper wires were connected to the phone, and two copper wires were connected from the phone, connected to the hand-crank generator, and ran back and forth twice. I confirmed that I was not wrong, but I dared not start the experiment.

"Try it." Renault said.

Seeing that Shuang had two more phone calls, Mo Xiang and Huya immediately ran over to grab the position. After all, there were two secret masters there, and they rarely had the chance to get started.

When Renault got up the next day, only Chu Rui was still guarding him and serving to wash, even Mo Xiang ran to play.

I heard from Chu Rui that everyone didn’t sleep last night and was still playing until now. Zhangtan’s thread squeezer never stopped, and he squeezed out several hundred meters of copper wire, which was continuously lengthened under the command of two secret masters.

The people around Renault were surprised by the function of the phone, but the secret masters were different. They looked farther and wanted to know more.

It doesn't matter, let them play. This simple shaking phone can reach five hundred meters in a call distance, so Renault is thankful. In fact, it is difficult to hear the sounds on the opposite side clearly from two hundred meters away. It is not that it cannot be transmitted so far, but that it cannot effectively reduce noise. While the signal is exhausted, the noise will increase.

There is also a hand-crank generator, which has too small power, is far away, is unstable, and the current becomes weak, exceeding five hundred meters, and is insufficient in power, and can't hear anything except noise.

In fact, with resistors, convex films, and hand-crank generators, Renault can make more practical things. For example, electric speakers and tweeters are definitely not possible. For ordinary electric speakers, it is not a problem to expand the sound ten times or even dozens of times. The difference is just the size of the speaker, and the principle is the same.

A sound group consisting of two speakers, the sounds emitted can be heard hundreds of meters away, which is much better than a manual telephone.

Renault was thinking, Bai Jing, and Fire came over and sat beside him, looking at the messy study room, frowned. The old secret master was very law-abiding and looked down on Renault's style, but this place was not their temple after all. Renault was a secret master like them, and even surpassed them in the research of secret techniques, which was difficult to scold, so at most I would just advise him.

"Renault, your place is too messy. The study room should be a forbidden area. Except for designated personnel, those who enter without permission will die." Bai Jing said.

"Those who are stubborn die? There is no need." Renault was shocked. Da Chu did not pay attention to human rights and did not take human lives seriously, but you are secret masters. Is this okay?

"Yes, rules must be established, otherwise, you will soon find that apart from solving these trivial matters, you will not have time to study secret techniques. The time of the secret master is very precious." Bai Jing said affirmatively.

"Not everyone can become a secret master at your age." Fire said. It was not easy for him to speak, and he really couldn't stand it anymore.

Renault naturally didn't know that if he had the chance, he would usually become an apprentice waiter around the secret master at the age of seven to ten, and if he was accepted by the secret master within ten years and became a true disciple, it would be very fast. It would be great to spend twenty to thirty years to inherit the teacher's legacy and become a true secret master.

In other words, becoming a secret master at the age of forty is the best result. However, the time for a secret master is spent on learning and research, and rarely spending time on martial arts practice. It is even rarer to become a master.

The lifespan of ordinary people is not long. The living conditions of secret masters are far more fun. Ordinary people usually live beyond 60 years old, and there are still not many who may live beyond 70 years old.

After counting this, after becoming a secret master, the time for only 20 or 30 years to truly study independently. During this period, you still have to get rid of rest and accept apprentices and other chores. The secret master's time is really not enough.

In fact, the inheritance of the secret master is much more complicated. The previous ones refer to the most ideal state. Where can there be such good things in the world? The secret master will also get sick and may die early.

If you calculate it again, you will know that a forty-year-old secret master will recruit ten-year-old children as apprentices. Everything will go smoothly. Only when the secret master is seventy years old can his students become a real secret master.

You will understand by counting this way. In fact, most students are unlikely to become secret teachers throughout their lives. During their learning process, the teacher is already dead.

"Thank you for your advice, I will pay attention in the future." Renault didn't care at all. He didn't think about studying anything. He just wanted to play with some small inventions. What he really cared about was when Cui Qing could burn out the toilet.

Of course, there is also porcelain. Shengong Hall was originally a palace family, so naturally there is no shortage of porcelain, but Renault really doesn't like those porcelains. No supermarket is willing to take over porcelain of this quality.

"Senior, I think there seems to be some connection between your surnames." Renault couldn't figure it out, so he simply asked directly.

Bai Jing, Fire Flame looked at each other, full of helplessness. What did this kid's family teach him? Why didn't he even know these common sense?

Besides, it’s great to study more mobile phones when you have time. What’s your last name? It’s nonsense.
