Renault now regrets that the crank phone is nothing more than a toy for him to be idle and bored, and wants to show his self-worth, yes, it is a toy.

Because Renault knows very well that with the current level of technology, the phone he makes is not much better than the earpieces that children play with.

A very simple little thing, two paper cups, drilled at the bottom, connected by a metal wire, after which you can talk to each other and hear each other's voices. Of course, the distance should not be too far, say twenty meters, or closer.

After all, it uses electrical energy and resistance to convert sound waves into electric shock, and then from electric shock to sound waves, the loss of this process will also be very large, so its noise and communication sound will be unbearable.

Renault thought so, but others didn't, Bai Jing and Flame arrived in half an hour later, and then there was nothing to do with Renault. Renault felt that the two secret masters who were so excited that they needed doctors the most now, and if they continued to be so excited, it would easily cause heart problems.

It was not only the two secret masters who were excited, but also the group of students that Renault had brought to play with before had also turned into science maniacs, following behind the butts of the two secret masters, and they had to try it when they had the chance.

In normal times, the two secret masters could drive them all out of the temple, but this was Renault's shrine, so they tried their best to restrain the dissatisfaction in their hearts and occupy the two phones as much as possible.

Mozi scratched his ears and cheeks anxiously, but his status here was the lowest, and he didn't even have a chance to get close. Murphy was very calm, never approaching, looking from afar, with envy in his eyes.

This thin boy, but he has a delicate heart, and seeing that he didn't have a chance to get started, he hit the idea on the box in the Zhang Tan, which still has a lot of parts.

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

But this is not enough, the things belong to Your Excellency, he is just a cat and a dog adopted by Your Excellency, and even he himself thinks that the animals in the Temple of Divine Work are more noble than him. For example, the purple shadow who is crazy, and the two big birds that have begun to practice flying.

Renault had already seen that Mozi was very good, a very smart young man, but he looked like a little stumbling: "Want to try?"

Anyway, being squeezed out, Renault sat in the corner of the study and drank tea, and asked softly.

"Your Excellency...... I ...... "Mozi was at a loss, he didn't know how to answer, in his more than ten years of life experience, the first thing he learned was to be humble and lowly.

"Then go for it. "Renaud doesn't care about this, if the people around him are like him in the future, they are so timid, they can't even say a complete sentence, it's too boring.

"I ...... Is it okay?" Mozi's guts were even smaller than Renault had imagined.

"Go ahead and do it boldly, it's nothing, you should know, these things are all created by Zhang Tan, even if you play badly, you can let him build it again. Renault said with a smile that development games are usually quite fun.

It's just,It seems a little wrong.,People play all Lori cultivation.,How did you get to yourself.,Become a Zhengtai cultivation?

Renault admitted that Mozi's name was too deceptive, so he couldn't help but want to cultivate the fake Mozi with the real Mozi.

In fact, he knew that it was impossible, Mozi on the earth could be worshiped by people for thousands of years, not because he knew anything, but when no one knew what he could invent.

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

Mozi stretched out her trembling little hand and took out the parts from the box, reminiscing and assembling them. And Renault fell back into deep thought.

The name of the Da Chu people is so interesting.

Luo Yi, a heroic figure in the late Sui and early Tang Dynasties, had a strong army called Yanyun Eighteen Cavalry under his command.

Renault's history is very average, the public level, and the names of people who can be remembered by him are famous in history.

Zhu Chongjiu, this name is more interesting, if I remember correctly, Zhu Yuanzhang, the founding emperor of the Ming Dynasty, was nicknamed Zhu Chongba, this is Lao Zhu's younger brother?

Li Si, Prime Minister of Great Qin, don't look at him as a small transparent person in the Shengong Palace, in fact, he is a serious master of eight hundred, such a person, in Shengjing Luocheng, with a population of more than one million, there are only more than 30 people.

Finally, there is Mozi, a giant bull with this name.

In fact, in addition to these people, Renault is most curious about the names of the two secret masters, Bai Jing, Flame, which sounds ordinary, but he feels that these two surnames seem to be related, and Renault has not figured it out for the time being.

Mozi has a pair of nimble little hands and a smart head, and it took half an hour to assemble two crank phones.

Two copper wires, connected to the telephone, and from the phone, two copper wires were connected, connected to the hand-cranked generator, and ran back and forth twice, confirming that there was no mistake, but I didn't dare to experiment.

"Try it. Renault said.

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

When Renault got up the next day, only Chu Rui was still by his side, waiting for freshening, and even Moxiang ran to play.

I heard Chu Rui say that last night, everyone didn't sleep, and until now, they are still playing. Zhang Tan's wire extruder did not stop, and hundreds of meters of copper wire were squeezed out, and under the command of the two secret masters, it was constantly lengthened.

These people around Renault were purely for fun and were amazed by the function of the phone, but the secret master was different, they looked farther and wanted to know more.

It doesn't matter, let them play, this simple crank phone, the talking distance can reach 500 meters, Renault is thankful, in fact, 200 meters away, it is difficult to hear the voice of the other side. It's not that it can't travel that far, but it can't effectively reduce noise, and when the signal fails, the noise will expand.

There is also a hand-cranked generator, the power is too small, the distance is far, the voltage is unstable, the current becomes weaker, more than 500 meters, the power is insufficient, except for noise, nothing can be heard.

In fact, with resistors, resonance sheets, and hand-cranked generators, Renault can make more practical things, such as electric horns, tweeters are definitely not possible, ordinary electric horns, it is not a problem to expand the sound tenfold, or even dozens of times, the difference is only the size of the horn, and the principle is the same.

A set of two speakers composed of a sound group, the sound can be heard hundreds of meters away, which is much better than a hand-cranked telephone.

As Renault was thinking, Bai Jing and Flame came over and sat beside him, looking at the somewhat messy study, his brow furrowed. The old secret master is very well-behaved, and he doesn't look down on Renault's style, but this is not their temple after all, Renault is a secret master like them, and even surpasses them in the study of secret arts, but it is not easy to reprimand, at most a few words of persuasion.

"Renault, you're too messy here, the study should be a forbidden place, except for designated personnel, trespassers die. Bai Jing said.

"Trespassers die, there's no need. "Renault was taken aback, Da Chu doesn't pay attention to human rights, and he doesn't take human life seriously, but you are a secret master, is this good?

"Yes, the rules still have to be established, otherwise, you will soon find out that you will not have time to study the secret arts except for solving these trivial things. The time of the Mystic is very precious. Bai Jing said affirmatively.

"Not everyone can become a secret master at your age. Flame said, it was not easy for him to speak, it was really unbearable.

Renault naturally didn't know that if he had the opportunity, usually at the age of seven to ten, he would become an apprentice attendant beside the secret master, and if he was accepted by the secret master within ten years and became a true disciple, this would already be very fast, and it would take another twenty to thirty years to inherit the mantle of the teacher and become a real secret master, which would be excellent.

In other words, at the age of forty, becoming a secret master is the best outcome. But the time of the secret master is spent on study and research, and he rarely spends time on martial arts practice, and it is even more rare to become a grandmaster.

The lifespan of ordinary people is not long, and the living conditions of secret masters are far more fun than ordinary people, usually they can live past the age of sixty, and those who may live past seventy are still not much.

In this way, after becoming a secret master, the time to really be able to study independently is only twenty or thirty years, and during this time, you have to remove miscellaneous things such as resting and accepting apprentices, and the time of the secret master is really not enough.

In fact, the inheritance of the secret master is far more complicated, and the previous ones refer to the most ideal state. Where in the world there is such a good thing, the secret master will also get sick and may die early.

If you go back and calculate it, you will know that the forty-year-old secret master takes a ten-year-old child as an apprentice, and everything goes well, and when the secret master is seventy years old, his students can become teachers and become real secret masters.

In fact, the vast majority of students are unlikely to become secret masters throughout their lives. In the process of their learning, the teacher is already dead.

"Thanks for the pointers, I'll pay attention to it later. Renault didn't care at all, he didn't think about what to study, play with some small inventions or something, just play, what he really cared about was Cui Qing's side, when he could burn the flush toilet.

Of course, there is also porcelain, the Shengong Hall was originally a palace family, so naturally there is no shortage of porcelain, but those porcelain, Renault really can't look down on it. No supermarket is willing to take over porcelain of this quality.

"Senior, I think there seems to be some kind of connection between the surnames of the two of you. Renault really couldn't figure it out, so he simply asked directly.

Bai Jing and Flame glanced at each other, full of helplessness, what did this kid's family teach him? Why don't you even know these common sense?

Besides, how good it is for you to study the hand-cranked phone in your spare time, what is your surname, and what is the relationship with fart.

"Of course there is a connection, they are all from the Xuan tribe. Bai Jing said.
