Otaku Engineer in Great Tang Dynasty

? Alas, Xiao Ke! You said that this copper coin is really troublesome to use. You have to pay for a lunch or two. You have to take a few pennies every time you eat. It would be great if the canteen of the college could use golden beans. It saves trouble! "

Cheng Chu silently hugged a coin box and couldn't help saying.

The Cheng family has made a lot of profits due to the cooperation with Li Zexuan to open a wine shop. Cheng Chumo has more pocket money now, and he is considered a rich man, otherwise he would not say such a thing!

Li Ke was taken aback, and then smiled: "Ugly cow, if you go to the cafeteria to eat with golden beans, if you dare to give it, others dare not accept it, because you will have to refund the money for a long time!"

"Hey! Xiaoke, what you said makes sense!"

Cheng Chu thought for a while, and smiled embarrassedly.

Li Ke was silent on his face, but he was lost in thought. During his "internship" at the Nuantang Foundation last year, he once mentioned to Li Zexuan that copper coins were not portable. At that time, Li Zexuan encouraged him to say that people from Yanhuang Academy , If he encounters a problem, he must solve the problem. If he can smoothly solve the problem of the inconvenience of copper coins, then he will create an era and stay in history!

Since then, he has been thinking about this issue in his heart. Today Cheng Chu is silent for a moment, but it has brought him a hint of inspiration, maybe it can be like this...

…………………………

In the next few days, Li Ke seemed to be like a demon. In addition to class every day, he was writing and drawing on a small book. Even on weekends, students would often see him in the classroom. Everyone is not so surprised, because they all think that Li Ke is studying hard! After all, in the last final exam, Li Ke entered the top three for the first time and beat Li Tai. If you want to stabilize this score, you have to work harder!

But the truth is not what everyone thinks!

On this day, Li Ke came to Li Zexuan's office.

"Shanchang, I have something to look for you!"

Li Ke knocked on the door and said to Li Zexuan.

"Yeah! Sit down and talk!"

Li Zexuan glanced at Li Ke, especially focusing on the booklet the child was holding, then pointed to the sofa opposite and smiled.

"Thank you Shan Chang!"

Li Ke thanked him, and sat on the sofa opposite, saying that now in the entire Datang, only Li Zexuan can enjoy such a soft sofa.

Sitting on the sofa with half of his hips, Li Ke organized some words in his heart and then said: "Shanchang, I have thought of a way to solve the inconvenience of carrying copper coins!"

"Huh? Come and listen!"

Li Zexuan glanced at Li Ke in surprise, and quickly put down a book in his hand to show a respectful look.

Li Ke was a little nervous, but he still plucked up the courage to say: "Shan Chang, I think if you want to solve the problem of inportability, you can set up a department in the college to provide students with copper money exchange services. In other words, students can Take the copper coin and exchange it for a paper voucher of corresponding value in the college. With this voucher, students can go to the cafeteria to eat, or go to Gu's small shop to buy things. The coin can be used anywhere in the college. This certificate replaces.

And every once in a while, in a small shop like Gu’s, you can take the received voucher and come to the academy to exchange it for copper. In this way, everyone will not lose money, and the transaction process will be much more convenient! Shan... Shan Chang, what do you think of this method? "

However, Li Ke said it for a long time, and he didn't see Li Zexuan responding, he suddenly asked with some falsehood.

"Haha! Good! Very good!"

Li Zexuan stood up suddenly, rubbed his palms and laughed. At this moment, he just wanted to say, Xiu! Tianxiu! Are the things that Li Ke just said are the prototypes of bank notes or paper money?

"Xiao Ke, you can think of this, it is very gratifying to be a teacher, but there are some problems in this, you need to think about it in advance!"

Li Zexuan first affirmed Li Ke's thoughts, and then brought Li Ke back from the cloud to bring it back to reality.

"Shanchang, what's the problem?"

Li Ke stared at Li Zexuan without blinking, and asked.

Li Zexuan smiled, stretched out a finger, and said: "First, first, you have to find a way to make students believe in your voucher and be willing to exchange it with copper coins. After all, no one has ever seen your voucher before. , Why are people willing to exchange their money into a piece of paper with you?

Second, when the students believe in you and are willing to exchange copper coins for vouchers, you have to find a way to get the voucher to believe that you can exchange the vouchers for copper coins, because the ultimate goal of merchants doing business is to make money. If only a few sheets of paper were earned in the end, who would be willing to do it? You don’t need to worry about the canteen, but Gu Xiaomao’s teacher cannot force him, you have to do it yourself;

The third and most important point is that you have to consider whether someone will imitate your voucher in the future and use it to make huge profits! Our Yanhuang Academy said that it is not big, but it is not too small. If someone forges the certificate, then the loss we have suffered should definitely not be underestimated! "

As Li Ke listened, he wrote down all the points mentioned by Li Zexuan in the pamphlet. After Li Zexuan said it, he stood up and arched his hands in silence for a while:

"Thank you for his teaching! Regarding the first and second points, the students will try their best to convince the students in their own colleges to believe this voucher. As for the third point, students want to be able to draw the patterns on the voucher to be complicated Click on it and put Shan Chang's personal seal on it. People are afraid that it is not easy to imitate, right?"

Li Zexuan shook his head and said, "Who said that the seal can't be copied? But if your voucher is only used in academies, it would be OK to do it! But I hope that this kind of transaction voucher can be promoted to the private sector in the future! So, Either you don't do it, Xiaoke, then do it flawlessly! It's hard for everyone in the world to imitate it!"

Li Ke's eyes widened~www.readwn.com~ incredible: "Shanchang, you... do you want the civilians and merchants to use this kind of voucher to trade?"

He would never have thought that Li Zexuan would play such a big game. If the people could also use his certificate, wouldn't he have created a new type of currency?

When he thought of this, Li Ke's breathing became a little quick.

Seeing Li Ke's reaction, Li Zexuan smiled lightly: "What's wrong? Do you remember what I told you two months ago? If you can smoothly solve the problem of inconvenient copper coins, then you will create an era. , And stay in the history! If you don't allow everyone in the world to use this certificate, how can you stay in the history?"
