"Don't be crowded! Come one by one and line up. Everyone will be able to get in line today~!"
Lantian County, Yanhuang Bank.
When the people learned that there was no commission for exchanging Tang Yuan at the bank in Lantian County and that they could get interest on deposits, they all flocked there with most of their copper coins. At this time, the sun was rising and the bank had just opened for business. There were already people around, and the servants in the bank quickly came out to maintain order and appease the excited hearts of the people!
After all, each of these people was carrying a large bag of copper coins. If there was a dispute over the queue, money could easily be lost. Considering this situation, Li Ke quickly sent someone to notify the county government officer of Lantian County. Let them come here to maintain law and order here.
But there are still too many people coming to save money, thousands of people! Although the streets in Lantian County are not narrow after reconstruction, they cannot accommodate so many people!
The entire street in front of the bank has been filled up!
“There are so many of us, will the bank stop accepting our money when it’s our turn later?”
"That's right! With so much money, it's impossible for the bank to collect all of it, right?"
Some people at the back couldn't help but look worried at this time.
The boy had obviously been trained before. Hearing this, he said loudly: "Don't worry, folks. Since Mr. Hou dares to say that you can save money to earn interest, our bank will definitely be able to absorb the money everyone saves, and we will definitely be able to guarantee it." Everyone’s deposits are safe! If you have something to do today and can’t wait, go ahead and do your work first, and wait until there are fewer people behind you to deposit money. Our bank will accept it without fail! I guarantee you this!”
The boy's words made the people feel at ease. Those people who were very low in the ranking were ready to go home with their copper money bags. After all, people had a lot of farm work to do at home this season.
But there were still some big players in the team who were worried and questioned: "You promise? You are just a boy, what guarantee can you give? If everyone listens to you and goes back now, what will happen if the bank doesn't accept the money tomorrow? What can you do?" What will compensate us for our losses?”
As soon as he finished speaking, there was a sparse echo from the crowd: "That's right! What guarantee can you give me as a servant? Who will pay for our losses then?"
"That's right! You can't go back! I must deposit all the copper coins in Yanhuang Bank today~!"
"Yes, yes! I'm not leaving!"
After such a fuss, the people who were preparing to go home suddenly stopped.
The boy who shouted just now couldn't help but flushed with anxiety when he saw this scene. But in this case, no matter how much he said, it would be of no use, because he was just a boy at the bank!
"His guarantee is useless, what about mine?"
At this moment, a young man walked out of the bank hall and said expressionlessly.
Although his voice was not loud, it could reach everyone's ears clearly.
"Who is this young man?"
"Shut up! That's His Royal Highness the King of Shu!"
"What? It's His Highness King Wu?"
Soon, someone recognized Li Ke, and the chaotic and turbulent scene calmed down instantly.
"Since all the fellow villagers recognize me, I will explain some things clearly in front of you today!"
Li Ke looked at the crowd and said loudly: "No commission, deposit money to earn interest, this is a preferential policy launched by Yanhuang Bank of Lantian County for all the people in our county. This policy is long-term and will never happen 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 solemn promise, the people suddenly burst into cheers.
After a while, the cheers subsided, and Li Ke continued: "In addition, I need to explain one thing to you in advance, that is, the deposit interest rate of Yanhuang Bank is not permanent. This month it is 1.75%, and it will be 1.75% next month. It may increase to 1.8 or 1.9%, but it may also drop to 1.7%. It may rise or fall.
But I can assure you that even if the deposit interest rate drops, it will not be lower than 1.6%, so you don’t have to rush to the bank to save money today. It will be the same when you have time when you have time! And maybe then the interest will be more and you will get more money! "
"What? Deposit interest rates may still rise?"
"Good boy! Can any of you help me calculate how much interest I can earn by depositing 100 Guan in one year if the interest rate is 1.9?"
"Master, if you save one hundred guans a year, you can get 1,520 fen! That's nearly two guans!"
"Haha! Okay! That five hundred guan is 10 guan interest! Let's go! There are many people today, so we won't compete with everyone to save money!"
"That's right! Don't be in a hurry to save money. I have to go to the mountain to water Bai Diazi today!"
"That's right! Save money when you have free time!"
After listening to what Li Ke said, those people at the back of the line, whether they were large households or ordinary people, turned around and left one by one. The people at the front of the line did not leave much, because although the future deposit interest rate It may go up, but it may also go down at the same time! It’s better to deposit your money in a bank today and have peace of mind!
Seeing that most of the people had finally dispersed, Li Ke couldn't help but breathed a sigh of relief. This couldn't be blamed on the small scale of Yanhuang Bank. The flow of people just now was too huge and scary. Even if the bank's scale expanded again, Even if it were ten times worse, he would still be unable to withstand it!
This is just like modern banks. Any bank branch will be overwhelmed if it welcomes 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 business method for banks. What banks need is a stable and long-term customer source!
"The rest of the people line up, go in one by one and hand the copper coins to the boy who counts money inside, and explain whether it is a survival period or a fixed term. Remember to take your bankbook and put your fingerprint on it~!"
Li Ke looked at
.....................
"Chief, you are here. I have something to ask you~!"
In the afternoon, Li Zexuan had just arrived at the workshop. Not long after, Li Tai found Li Zexuan with a pile of messy drawings.
"Uh...Qingque, have you been awake all night?"
Li Zexuan said in shock.
Because at this time, Li Tai's hair was disheveled and his eye circles were dark, which was very inconsistent with the little fat man's usual clean character. It was obvious that he didn't sleep or didn't sleep well last night!
Li Tai scratched his head, making his already disheveled hair suddenly look more like a chicken coop, "Shan Zhang, I didn't think about something last night, so I read a little more and slept for a while. It’s an hour. Chief Shan, please help me solve a few problems quickly, otherwise I won’t be able to sleep well tonight~!”
It’s over!
Looking at the little fat man's appearance, he is obviously possessed! Just like Wang Ji back then!
"What's the problem? Just tell me~!"
In order to let the little fat man have a good sleep, Li Zexuan took Li Tai to a conference room and said.
Li Tai put down the drawing in his hand, looked at Li Zexuan, and said: "Shan Zhang, I have figured out the working principles and manufacturing processes of this DC motor, battery, and diode, but I heard Professor Mo say yesterday that you mentioned to her before However, there is another electronic device that can amplify current. It seems to be called a triode, which is modified based on the principle of a diode. Can you tell me about it in detail?"
Li Zexuan was slightly surprised and said: "Qingque, why do you suddenly want to hear this?"
Li Tai replied: "Mr. Shan, I think we can do many, many things with the transistor's ability to amplify current. For example, we can use it to increase the transmission power of the telegraph machine. In addition, I believe there are also There are many places where it can be used, and 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 away. He tapped the table lightly with his fingers. After pondering for a moment, he said solemnly:
"You are right, Qingque, the triode is indeed very important! It seems that the academy's second project-killing plan should be launched~!"
"The second trump card project?"
Li Tai screamed in surprise, and suddenly said with excitement: "Chief, is this second trump card project related to the telegraph machine?"
Li Zexuan nodded and said: "That's right! But before I go into details, I have to confirm, Qingque, are you willing to participate in the academy's second trump card project?"
Li Tai replied without thinking: "Yes! Yes! Of course I am willing!"
Li Zexuan said happily: "Okay! Today I will briefly tell you about this second killer project! The main purpose of this project is to improve the existing telegraph machine so that it can achieve ultra-long distance wireless communication. This Ultra-long distance should mean at least a thousand miles!"
"A thousand miles?"
Li Tai opened his mouth in shock and said in horror: "Wouldn't that be able to cover the entire Tang Dynasty?"
Li Zexuan nodded and said: "Yes! Although this sounds a bit exaggerated, from a technical perspective, it is not impossible! With diodes and triodes, we can increase the transmission power of telegraph machines on the one hand, and on the other hand, we can manufacture Detectors can be used to enhance the ability of telegraph machines to identify useful information in electromagnetic waves. In addition, we can also establish telegraph relay stations in major states and counties to receive and transmit electromagnetic waves. With this three-pronged approach, it is absolutely impossible to realize communication over thousands of miles. Any difficulty~!”
Although Li Zexuan's words have simplified the description as much as possible, they still contain a lot of professional terms. Li Tai listened with half-understanding, "Chief, if the improved telegraph can really do what you said, , realizing communication over thousands of miles, then our Datang Dynasty is likely to be majestic all over the world in the future!"
Li Zexuan smiled and said:
"It's not very possible, but it's for sure! The Tang Dynasty will definitely become stronger and stronger and invincible in the world! In fact, this second trump card project has another purpose, that is, through this improvement of the telegraph machine, Yanhuang Academy will Datang laid a certain foundation for the future electronics industry!
Like the electronic diodes before, as well as the electronic triodes, resistors, capacitors, inductors, etc. that will be made later, we have to find a way to produce some basic electronic components. Only in this way will we be able to make telegraph machines later. A more advanced and convenient communication tool~! "
Li Tai listened with fascination. Hearing this, he couldn't help but said with excitement: "Student Li Tai, I am willing to help the mountain!"
Although he gave up his desire to fight for the throne, he was still a Tang man after all. He hoped that the Tang Dynasty would become stronger, especially after he learned "Geography" in the academy and learned that the family was so big and there were so many countries. His desire to make Datang invincible in the world became even stronger!
The pride and national honor of the Tang people are difficult for others to understand.
Li Zexuan smiled and said: "You are talented and like to delve into research. Of course you are indispensable for this second trump card project! I just hope you won't complain about being tired when the time comes!!"
Li Tai shook his head and said: "Don't worry, Commander, I have survived the military training. There is nothing in this world that I, Li Tai, can't overcome! Please teach me how to make a triode!"
Otherwise, military training is the most tempering thing. After experiencing military training, the little fat man was full of courage to overcome all difficulties, because he already felt that nothing in the world was more difficult than military training!
Li Zexuan nodded. He picked up the drawing in Li Tai's hand and began to write and draw: "To say that this triode is based on the transformation of a diode is not wrong at all, because compared to the diode, the triode just has one more Grid. The so-called grid is a mesh-like or spiral electrode composed of metal filaments. It controls the intensity of the electric field on the surface of the cathode to change the electrons emitted by the cathode or capture the secondary emitted electrons. You can make it like this... …”
Half a quarter of an hour later, Li Tai finally understood the working principle and production method of the electronic triode. After digesting it for a while, the little fat man frowned and said:
"Mr. Shan, after the transistor is made, how can I be sure that it can indeed amplify the current? Do I have to connect a light behind it and judge the strength of the current based on the brightness of the light?"
This question can be regarded as stopping Li Zexuan.
After a long silence, 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. Firstly, it's inaccurate, and secondly, it's too troublesome. So, I think it's time to start Yanhuang Academy's third trump card project!"
Hearing this, Li Tai almost somersaulted off the chair. After he calmed down, he said with some surprise: "The third trump card project? Chief, is this a bit too fast?"
I haven’t even started the second one yet!
Li Zexuan shook his head and said: "It is indeed a bit too fast, but this is also a helpless move. The academy's technology is developing too fast, and many basic equipment cannot keep up, so we can only carry out multiple killer projects together!"
Li Tai thought for a while and felt that what Li Zexuan said made sense. He sighed helplessly and said, "Chief, what is the third trump card project?"
Li Zexuan said slowly: "Ammeters, voltmeters, and other basic instruments! The academy should take this opportunity to establish its own standards committee!"
