"Don't squeeze! Come one by one, line up, everyone will definitely be able to line up today~! ”

Lantian County, Yanhuang Qianzhuang.

When the people learned that the exchange of Tang Yuan in Lantian County was free of commission, and they could get interest on saving money, they all flocked to the house with most of the copper coins at home, at this time, the sun was rising, the money village had just opened for business, and the front of the door was already full of people, and the small people in the money village hurriedly came out to maintain order and appease the excited hearts of the people!

After all, these people are each carrying a large bag of copper coins, if there is a dispute because of the queuing problem, it is easy to lose money, considering this situation, Li Ke hurriedly asked people to notify the officials of the county government of Lantian County, and asked them to come over to maintain law and order here.

But there are still too many people who come to save money, there are thousands of people! Although the streets of Lantian County are not narrow after renovation, they can't stand so many people!

The whole street in front of the money village has been completely stuffed!

"There are so many of us, will the money bank stop taking our money when it's our turn to be behind?"

"That's right! With so much money, it is impossible for the money bank to collect it all, right? ”

Some of the people who were at the back of the queue couldn't help but say worriedly at this time.

The little guy was obviously trained before, and when he heard this, he said loudly: "Fellow villagers, rest assured, since Master Hou dares to let go and save money to earn interest, our money village will definitely be able to eat the money saved by everyone, and we will definitely be able to ensure the safety of everyone's deposits!" If you have something to do today, you can't wait, just go to work first, and wait until there are fewer people in the back to save money, and our money will be accepted as it is! I promise you! ”

The words of the little maid made the people feel a little at ease, and those people who were very low in the ranking were ready to go home with copper money bags, after all, the people had a lot of farm work to do at home this season.

But there are still some big families in the team who are not at ease, and they questioned: "You promise? You are a little guy, what guarantee do you get? If you listen to you and go back now, what if you don't collect the money tomorrow? What do you use to compensate us for our losses? ”

As soon as the words fell, a sparse echo suddenly sounded in the crowd: "That's right! What guarantee do you have for a little guy? Who will pay for our losses when the time comes? ”

"That's right! Can't go back! Today, the old man must deposit all the copper coins in Yanhuang Qianzhuang~! ”

"Yes, yes, yes! Don't go! ”

After such a commotion, the people who were about to go home suddenly stopped.

The little guy who shouted just now, seeing this scene, couldn't help but blush, but in this case, even if he said more, it would be useless, because he was just a small guy in the money bank!

"His promises are useless, what about mine?"

At this moment, a teenager walked out of the hall of the money village and said with an expressionless face.

His voice wasn't loud, but it was just right to reach everyone's ears clearly.

"Who is this young man?"

"Shut up! That's His Royal Highness the King of Shu! ”

"What? It turned out to be His Royal Highness King Wu? ”

Soon, someone recognized Li Ke, and the chaotic scene calmed down instantly.

"Since all the villagers know this king, then this king will explain some things clearly in front of you today!"

Li Ke looked at everyone and said loudly: "No commission, save money to earn interest, this is a preferential policy launched by Yanhuang Qianzhuang in Lantian County for all the people in our county, this policy is long-term, it will definitely not be there today, it will be gone tomorrow, I promise you in the name of the King of Shu~!" ”

"Your Highness is wise~!"

"Your Highness is mighty~!"

After hearing Li Ke's pledge, the people suddenly burst into cheers.

After a while, the cheers gradually stopped, and Li Ke continued: "In addition, there is one thing that this king needs to explain to you in advance, that is, the deposit interest rate of Yanhuang Qian Zhuang is not permanent, 1.75% this month, it may increase to 1.8 or 1.9% next month, but it may also decrease to 1.7%, it may rise or fall."

But I can assure you that even if the deposit rate falls, it will not fall below 1.6%, so you don't have to rush to deposit money today, and when you have time, you can save money again! And maybe there will be more interest and more money you will get! ”

"What? Is deposit rates likely to rise? ”

"Good boy! Can any of you help you calculate how much interest you can earn in a year if the interest rate is 1.9? ”

"Master, a hundred can have fifteen or twenty wen a year! It's almost two dollars! ”

"Haha! Good! That's 500 yuan is 10 percent interest! Walk! There are a lot of people today, so let's not rush to save money with everyone! ”

"That's right! I'm not in a hurry to save money, I'm going to the mountains to water Bai Diezi today! ”

"Yes, yes! Save money when you're free! ”

Hearing Li Ke say this, those people at the back of the line, whether they were big households or ordinary people, turned around and left one by one, and the people at the front of the line didn't go much, because although the deposit interest rate may rise in the future, it may also fall! It's better to save your money in the bank today!

Seeing that a large part of the people had finally dispersed, Li Ke couldn't help but breathe a sigh of relief, this can't be blamed for the small scale of Yanhuang Qianzhuang, it is really that the flow of people just now is too large and too scary, even if the scale of Qianzhuang expands tenfold, it will not be able to withstand it!

This is just like a modern bank, any bank branch will be overwhelmed by thousands of depositors who want to deposit money at the same time. Moreover, this sudden surge in customers is not a healthy and long-term way of operation for Qianzhuang, what Qianzhuang needs is a stable and long-term source of customers!

"The rest of the people lined up, went in one by one and handed over the copper coins to the little guy who counted the money inside, and explained whether it was a survival period or a regular period, remember to take your passbook and press your handprints on it~!"

Li Ke watched

....................

"Mountain Chief, you're here, I just have something to ask you~!"

In the afternoon, Li Zexuan just came to the workshop, and not long after that, Li Tai found Li Zexuan with a mess of drawings.

"Uh... Qingque, you haven't slept all night? ”

Li Zexuan was stunned.

Because Li Tai's hair is messy and his eye circles are black at this time, this is very inconsistent with the little fat man's always clean character, obviously he didn't sleep last night or didn't sleep well!

Li Tai scratched his head, making his already unkempt hair suddenly become more like a chicken coop, "Mountain Chief, I didn't figure out some things last night, so I read a book for a while, and I still slept for a few hours." Chief, help me solve a few problems, otherwise I won't be able to sleep well tonight~! ”

Finished!

Looking at the appearance of the little fat man, he is obviously obsessed! It's the same as the original Wang Jidime!

"What's the problem? You say~! ”

In order to let the little fat man get a good night's sleep, Li Zexuan took Li Tai to a conference room and said.

Li Tai put down the drawings in his hand, looked at Li Zexuan, and said: "Chief Shan, I have figured out the working principle and manufacturing process of this DC motor, battery, and diode, but I heard Professor Mo say yesterday that you mentioned to her before that there is also an electronic device that can amplify the current, which seems to be called a triode, which is transformed according to the principle of the diode, can you tell me in detail?" ”

Li Zexuan was slightly surprised: "Qingque, why do you suddenly want to hear this?" ”

Li Tai replied: "Shan Chang, I think that with the ability of the triode to amplify the current, we can do a lot of things, for example, we can use it to increase the transmission power of the telegraph, in addition, I believe that there are many places where it can be used, it is very important, so I think we should build it as soon as possible~!" ”

Hearing this, the surprise in Li Zexuan's eyes flashed for a moment, he gently knocked on the table with his fingers, and after a moment of silence, he said solemnly:

"Qingque, you are right, the triode is indeed very important! It seems that the Academy's second killing project plan should be launched~! ”

"The second killer project?"

Li Tai was shocked, and suddenly said with an excited face: "Mountain Chief, could it be that this second killer project is related to the telegraph?" ”

Li Zexuan nodded and said, "That's right! But before I go into details, I have to confirm whether you are willing to participate in the second killer project of the academy! ”

Li Tai replied without thinking: "Yes!" Willing! Of course I do! ”

Li Zexuan was pleased: "That's good! Today, I'll tell you a little bit about this second killer project! The main purpose of this project is to improve the existing telegraph so that it can achieve ultra-long-distance wireless communication, which should mean at least 1,000 miles! ”

"A thousand miles?"

Li Tai's mouth opened wide in shock, and he said in shock: "Wouldn't that cover the entire Tang Dynasty?" ”

Li Zexuan nodded and said, "That's right!" This may sound like an exaggeration, but technically, it's not impossible! With diodes and transistors, on the one hand, we can increase the transmission power of the telegraph, on the other hand, we can manufacture geophones to enhance the ability of the telegraph to identify useful information in the electromagnetic waves, in addition, we can also establish telegraph relay stations in major states and counties to do electromagnetic wave reception, transmission relay, so that the three-pronged approach, there is no difficulty in realizing thousands of miles of communication~! ”

Although Li Zexuan's words have simplified a lot of descriptions as much as possible, they still contain a lot of professional terms, and Li Tai listened to them with half understanding, "Shan Chang, if the improved telegraph can really achieve thousands of miles of communication as you said, then it is very likely that our Datang will be majestic all over the world in the future!" ”

Li Zexuan smiled:

"Not very likely, for sure! Datang can definitely become stronger and stronger and invincible in the world! In fact, this second killer project has another purpose, that is, through the improvement of the telegraph machine this time, Yanhuang Academy will lay a certain foundation for the future electronics industry of Datang!

Like the previous electronic diode, as well as the electronic transistor, resistor, capacitor, inductor, etc., some basic electronic components, we have to find a way to produce them, only in this way, we can make it possible to manufacture more advanced and more convenient communication tools than the telegraph~! ”

Li Tai was fascinated when he heard it, and when he heard the words, he couldn't help but say excitedly: "Student Li Tai, I am willing to help the mountain grower!" ”

Although he gave up the heart of competing for the crown, he is still a Tang man after all, and he hopes that Datang can become stronger, especially after he learned "Geography" in the academy, after learning that the family is so big and there are so many countries, his desire to make Datang invincible in the world is even stronger!

The pride and national honor of the Tang people are incomprehensible to others.

Li Zexuan smiled and said, "You are talented and intelligent, and you like to study, this second killer project, of course, is indispensable to you!" I just hope that you don't complain about being tired when the time comes!! ”

Li Tai shook his head and said: "Don't worry, the mountain chief, I have survived the military training, and there is no hurdle in this world that I Li Tai can't pass!" Teach me how to make a transistor! ”

How else to say that military training is the best way to hone people, after experiencing military training, the little fat man is full of courage to overcome all difficulties, because he already feels that there is nothing more difficult in this world than military training!

Li Zexuan nodded, he picked up the drawings in Li Tai's hand, and began to write and draw: "If you want to say that this transistor is based on a diode, it is not wrong at all, because compared to the diode, the triode is just one more gate." The so-called gate is a screen-shaped or spiral-shaped electrode composed of metal filaments, which controls the electric field strength on the surface of the cathode to change the electrons emitted by the cathode or capture the secondary radioactive electrons......

Half an hour later, Li Tai finally understood the working principle and production method of the electronic transistor, and after digesting it for a while, the little fat man frowned and said:

"Yamaga, after the triode is made, how can I be sure that it can indeed amplify the current? Is it necessary to judge the strength of the current by connecting an electric lamp to the back and judging the intensity of the electric lamp? ”

This question can be regarded as stopping Li Zexuan.

After being silent for a long time, just when Li Tai was about to lose his patience, Li Zexuan finally spoke, he looked at Li Tai with some sympathy, and said:

"Of course you can't use this method, it's inaccurate, and it's too troublesome, so I think it's time to start the third killer project of Yanhuang Academy!"

Hearing this, Li Tai almost came down from the chair with a heel, and after a while, he was a little stunned and said, "The third killer project? Isn't this a little too fast? ”

The second one hasn't even started yet!

Li Zexuan shook his head and said: "It's indeed a bit too fast, but this is also a helpless move, the technology of the academy is developing too fast, and many basic equipment can't keep up, so it can only be carried out together with multiple killer projects!" ”

Li Tai thought about it and felt that what Li Zexuan said was also reasonable, he sighed helplessly and said, "Mountain Chief, what is the third killer project?" ”

Li Zexuan said slowly: "Ammeter, voltmeter, and some other basic instruments!" The College would like to take this opportunity to set up its own Standards Committee! ”
