"Don't push! Come one by one and line up properly. Everyone will definitely be able to line up today! "
Lantian County, Yanhuang Bank.
When the commoners found out that the Lantian County Bank did not charge any commission and that they could earn interest from saving money, they all brought along most of their copper coins and flocked over. At this moment, the sun had just risen and the bank had just opened for business. The door was already filled with people. The manservants in the bank quickly came out to maintain order and calm the excited hearts of the commoners!
After all, these commoners were all carrying a large bag of copper coins. If there was a dispute because of queuing, it was easy to lose money. Considering this situation, Li Ke hurriedly sent someone to inform the Lantian County's yamen runners to come over and maintain the law and order here.
However, there were still too many people who came to save money. There were more than a thousand people! Although the streets of Lantian County were not narrow after the renovation, it could not accommodate so many people!
The entire street in front of the bank was filled with people!
"There are so many of us. Will the bank not take our money when it's our turn?"
"That's right! There's so much money. The bank can't take it all, right? "
Some of the commoners who were queuing at the back could not help but worry.
The manservant of the bank had clearly been trained. Hearing this, he said loudly, "Don't worry. Since Marquis dares to say that we can save money to earn interest, our bank will definitely be able to take in everyone's money. Furthermore, we will definitely be able to guarantee the safety of everyone's savings! If you have something to do today and cannot wait, go ahead and do it first. Wait until there are fewer people behind you to save money. Our bank will take it all! This, I guarantee you! "
The manservant's words made the commoners feel more at ease. Those who were queuing at the back were prepared to carry their bags of copper coins home. After all, the commoners had a lot of farm work to do during this season.
However, there were still some rich people in the queue who were not at ease. They questioned, "You guarantee? You're just a manservant. What guarantee do you have? If everyone listens to you and goes back now, what if the bank doesn't take the money when they come back tomorrow? What will you use to compensate us for our losses? "
The moment he said that, there were sparse voices of agreement from the crowd, "That's right! You're just a manservant. What guarantee do you have? When the time comes, who will compensate us for our losses? "
"That's right! We can't go back! Today, I must deposit all my copper coins in the Yanhuang Bank ~! "
"Right, right, right! I'm not leaving! "
After such a commotion, the people who were preparing to go home immediately stopped in their tracks.
The manservant who shouted earlier couldn't help but blush when he saw this scene. However, no matter how much he said, it was useless because he was only a manservant of the bank!
"If his promise is useless, then what about mine?"
At this moment, a young man walked out of the bank's hall and said expressionlessly.
Although his voice wasn't loud, it was loud enough to be heard clearly by everyone.
"Who is this young man?"
"Shut up! That's His Highness, King of Shu! "
"What? It's His Highness, the King of Shu? "
Soon, someone recognized Li Ke. The chaotic scene instantly calmed down.
"Since everyone recognizes this Prince, then this Prince will make some things clear in front of all of you today!"
Li Ke looked at the crowd and said in a clear voice, "Waiving commission and saving money to earn interest is a preferential policy that the Yan Huang Bank of Lantian County has introduced to all the people in our county. This policy is long-term and will definitely not be gone tomorrow. I, in the name of the King of Shu, promise all of you ~!"
"Your Highness is wise ~!"
"Your Highness is mighty ~!"
After hearing Li Ke's solemn promise, the people immediately burst into cheers.
After a while, the cheers gradually died down. Li Ke continued, "Also, there is something that this Prince needs to tell all of you in advance. That is, the deposit interest rate of the Yanhuang Bank is not fixed forever. This month, it is 1.75%. Next month, it may increase to 1.8%, 1.9%, or it may decrease to 1.7%. It may increase, and it may decrease.
However, this Prince can promise all of you that even if the deposit interest rate decreases, it will not be lower than 1.5%. Therefore, there is no need for everyone to rush to the bank to deposit money today. It will be the same when you have time to deposit money! Moreover, the interest rate might be higher by then! "
"What? The deposit interest rate can still increase? "
"Good! Can any of you calculate for me? If the interest rate increases to 1.9%, how much interest would a hundred strings of cash earn in a year? "
"Old Master, a hundred strings of cash earn 1520 copper coins in a year! That's close to two strings of cash! "
"Haha! Good! Then five hundred strings of cash will be ten strings of cash! Let's go! There are so many people today. Let's not fight with everyone to save money! "
"That's right! There's no rush to save money. I still have to go up the mountain to water the white stack today! "
"Yes, yes! I'll save money when I have time! "
Hearing Li Ke's words, those at the back of the line, whether they were rich or ordinary people, all turned and left. Those at the front of the line did not leave. Although the deposit interest rate could increase in the future, it could also decrease at the same time! They might as well save their money in the bank today and be at ease!
Seeing that most of the people had left, Li Ke could not help but heave a sigh of relief. This could not be blamed on the small scale of the Yanhuang Bank. It was just that the flow of people just now was too huge and too scary. Even if the bank's scale was ten times bigger, it would not be able to handle it!
This was just like a modern bank. If a bank received thousands of depositors at the same time, it would not be able to handle it. Moreover, this sudden surge of customers was not a healthy and long-term way for the bank to operate. What the bank needed was a stable and long-term source of customers!
"The rest of the people, line up and go in one by one. Pass the copper coins to the servant who is counting the money. Also, tell him whether you want to deposit it for a current or fixed period. Remember to take your passbook and put your fingerprint on it!"
Li Ke looked at the remaining commoners and ordered loudly.
…
"Yamachō, you're here. I have something to ask you!"
In the afternoon, Li Zexuan had just arrived at the workshop. Not long after, Li Tai came to Li Zexuan with a messy stack of blueprints.
"Er … Qingque, you didn't sleep last night?"
Li Zexuan was stunned.
This was because Li Tai's hair was messy and there were dark circles under his eyes. This did not match the little fatty's usual clean image. It was obvious that he did not sleep last night or did not sleep well!
Li Tai scratched his head, causing his already messy hair to look even more like a chicken's nest. "Yamachō, there were some things that I couldn't figure out last night, so I read a little more. However, I still slept for a few hours. Yamachō, quickly help me solve a few problems. Otherwise, I won't be able to sleep well tonight! "
It's over!
Looking at the little fatty's appearance, it was obvious that he was possessed! Just like Wang Jiyi back then!
"What problems? Tell me ~! "
In order to let the little fatty have a good night's sleep, Li Zexuan brought Li Tai to a meeting room and said.
Li Tai put down the blueprints in his hand and looked at Li Zexuan. "Yamachō, I've already figured out the working principle and manufacturing process of the DC motor, battery, and diode. However, I heard from Professor Mo yesterday that you mentioned to her that there's an electronic device that can amplify current. I think it's called a transistor. It's based on the principle of the diode. Can you tell me more about it?"
Li Zexuan was slightly surprised. "Qingque, why do you suddenly want to hear this?"
Li Tai replied, "Yamachō, I think that with the transistor's ability to amplify current, we can do a lot of things. For example, we can use it to increase the transmission power of the telegraph. Other than that, I believe that it can be used in many other places. It's very important, so we should build it as soon as possible ~!"
Hearing this, Li Zexuan's eyes flashed with surprise. He tapped the table lightly with his finger. After a moment of silence, he spoke with a serious expression.
"Qingque, you're right. The transistor is indeed very important! It seems that the Academy's second killer project is about to start ~! "
"The second killer project?"
Li Tai exclaimed in surprise. Suddenly, he said excitedly, "Yamachō, does the second killer project have something to do with the telegraph?"
Li Zexuan nodded. "That's right! But before we talk about it, I have to confirm if you're willing to participate in the Academy's second killer project! "
Li Tai didn't even think before replying, "I'm willing! Yes! Of course I'm willing! "
Li Zexuan was gratified. "That's good! Today, I'll briefly explain the second killer project to you! The main purpose of this project is to improve the existing telegraph so that it can achieve ultra-long distance wireless communication. This ultra-long distance should be at least a thousand miles! "
"A thousand miles?"
Li Tai opened his mouth in shock. "Then wouldn't it be able to cover the entire Tang Empire?"
Li Zexuan nodded. "That's right! Although this sounds a little exaggerated, it's not impossible from a technical point of view! With the transistor and the diode, we can increase the transmission power of the telegraph. On the other hand, we can create detectors to enhance the telegraph's ability to identify useful information in electromagnetic waves. In addition, we can set up telegraph relay stations in the various provinces and counties to receive and transmit electromagnetic waves. With this three-pronged approach, it won't be difficult to achieve ultra-long distance communication ~! "
Although Li Zexuan's explanation was simplified as much as possible, there were still many technical terms in it. Li Tai only understood half of it. "Yamachō, if the improved telegraph can really achieve ultra-long distance communication as you said, then our Tang Empire will very likely dominate the world in the future!"
Li Zexuan smiled.
"It's not just very likely, it's definitely! Tang Empire will definitely become stronger and stronger, and become invincible in the world! In fact, the second trump card project has another purpose, and that is to use the improved telegraph to lay a certain foundation for Tang Empire's electronic industry in the future!
For example, the electronic diode, the transistor, the resistor, the capacitor, the inductor, and so on. We have to find a way to produce some basic electronic components. Only then will we be able to produce more advanced and convenient communication tools than the telegraph! "
Li Tai listened attentively. Hearing this, he couldn't help but excitedly clasp his hands and say, "Student Li Tai is willing to help Yamachō!"
Although he had given up on fighting for the throne, he was still a Tang Empire citizen. He hoped that Tang Empire could become stronger, especially after he learned Geography at the Academy. After he understood how big the aristocratic families were and how many countries there were, his desire to make Tang Empire invincible in the world became even stronger!
The pride and national honor of the Tang Empire was incomprehensible to others.
Li Zexuan smiled and said, "You are talented and smart, and you like to study. Of course, this second trump card project can't be done without you! I just hope that you won't complain about being tired when the time comes! "
Li Tai shook his head and said, "Yamachō, don't worry. I've survived the military training. There's no obstacle in this world that I, Li Tai, can't overcome! Quickly teach me how to make the transistor! "
That was why it was said that military training was the best way to train people. After going through the military training, the little fatty was filled with the courage to overcome all difficulties, because he already felt that there was nothing more difficult than military training in this world!
Li Zexuan nodded. He picked up the blueprint in Li Tai's hand and began to write and draw. "It's not wrong to say that the transistor is based on the diode, because compared to the diode, the transistor only has an additional grid. The so-called grid is a mesh or spiral electrode made of metal filaments. It controls the electric field on the surface of the cathode, thus changing the cathode's emission of electrons or capturing the secondary emission of electrons. Qingque, you can make it like this … "
After Li Zexuan's explanation and step-by-step teaching, Li Tai finally understood the workings of the transistor and how to make it. After digesting it for a while, the little fatty frowned and said,
"Yamachō, after the transistor is made, how can I be sure that it can really amplify the current? Do I have to connect an electric lamp at the back and judge the strength of the current based on the brightness of the lamp? "
This question stumped Li Zexuan.
After a long silence, just as Li Tai was about to lose his patience, Li Zexuan finally spoke. He looked at Li Tai with some sympathy and said,
"Of course we can't use this method. Firstly, it's not accurate, and secondly, it's too troublesome. Therefore, I think it's time to start Yanhuang College's third trump card project!"
Hearing this, Li Tai almost fell off his chair. After calming down, he said with some surprise, "The third trump card project? Yamachō, isn't this a bit too fast? "
The second project hasn't even started, and you're already starting the third?!
Li Zexuan shook his head and said, "It's a bit too fast, but we have no choice. The Academy's technology is developing too fast, and many of the basic facilities can't keep up. We can only carry out the trump card projects together!"
Li Tai thought for a while and felt that Li Zexuan's words made sense. He sighed helplessly and said, "Yamachō, what's the third trump card project?"
Li Zexuan said slowly, "The ammeter, the voltmeter, and some other basic instruments! The Academy wants to take this opportunity to set up its own standards committee! "
