Alas, Xiao Ke! You said that this copper coin is really troublesome to use, how to eat a lunch has to be one or two, and every time you eat, you have to take a few copper coins, if only the cafeteria of the academy could use gold beans, it will save more trouble! ”

Cheng Chumo held a copper coin box and couldn't help but say.

The Cheng family has made a lot of profits due to the relationship between the Cheng family and Li Zexuan to open a wine shop, and Cheng Chumo now has more pocket money, and he can be regarded as a rich man, otherwise he would not have said such a thing!

Li Ke was stunned for a moment, and then smiled: "Ugly cow, if you take the golden beans to the canteen to eat, you dare to give it, and people don't dare to accept it, because you have to return the money for half a day!" ”

"Hey, hey! Xiao Ke, what you said also makes sense! ”

Cheng Chu thought for a moment and smiled embarrassedly.

Li Ke's face was silent, but his heart fell into contemplation, last year in the Nuan Tang Foundation "internship", he once mentioned to Li Zexuan the inconvenience of copper coins, at that time Li Zexuan encouraged him to say that the people of Yanhuang Academy, when they encounter problems, they must solve problems, if he can successfully solve the problem of copper coins are inconvenient to carry, then he will create an era, and his name will go down in history!

Since then, he has been pondering this question in his heart, and today's silent words brought him a hint of inspiration, maybe it can be like this......

…………………………

In the next few days, Li Ke seemed to follow the devil, in addition to class every day, he wrote and painted in a small book, even on weekends, students can often see him in the classroom, for this, everyone is not very strange, because they all think that Li Ke is studying hard! After all, Li Ke entered the top three for the first time in the final exam last time, beating Li Tai by the head, if you want to stabilize this result, then you have to work harder!

But the truth is not at all what everyone thinks!

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

"Mountain Chief, I have something to look for you!"

Li Ke knocked on the door, looked at Li Zexuan and said.

"Hmmm! Sit down and talk! ”

Li Zexuan glanced at Li Ke, especially the booklet that the child was holding, then pointed to the sofa opposite, and said with a smile.

"Thank you, Chief!"

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

Sitting on the sofa with half of his buttocks, Li Ke organized some language in his heart and then spoke: "Mountain Chief, I have thought of a way to solve the problem that copper coins are not easy to carry!" ”

"Huh? Come and hear it! ”

Li Zexuan glanced at Li Ke in surprise, and hurriedly put down a book in his hand and put on a deaf look.

Li Ke was a little nervous in his heart, but he still mustered up the courage to say: "Chief Shan, I think that if you want to solve the problem of inconvenience in carrying, you can set up a special department in the academy to provide students with copper coin exchange services, that is, students can take copper coins and exchange them for paper vouchers of corresponding value in the academy, with this voucher, students can go to the cafeteria to eat, or go to the Gu family's small shop to buy things, and wherever copper coins are used in the academy, they can use this voucher instead."

And every once in a while, like the Gu family's shop, you can take the voucher you received and come to the academy to exchange it for copper coins, so that everyone will not lose money, and the transaction process will be much easier! Mountain...... Yamana, what do you think of this method? ”

But it was Li Ke who said for a long time, and he didn't see Li Zexuan responding, so he suddenly asked a little weakly.

"Haha! Good! Very good! ”

Li Zexuan suddenly stood up, stroked his palms and laughed, at this moment he just wanted to say, show! Tianxiu! What Li Ke just said, aren't they the prototype of silver tickets or banknotes?

"Xiao Ke, it's very gratifying that you can think of this, but there are also some problems in this, you need to think about it in advance!"

Li Zexuan first affirmed Li Ke's thoughts, and then pulled Li Ke back to reality from the clouds.

"Mountain Chief, 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 first have to find a way to make the students believe in your voucher, and be willing to exchange copper coins for it, after all, others have never seen your voucher before, why are people willing to exchange their money for a piece of paper with you?"

Second, when the students believe in you and are willing to exchange copper coins for vouchers, you also have to find a way to make the person who collects the vouchers believe that you can exchange this voucher for copper coins, because the ultimate goal of businessmen is to make money, and if they only earn a few pieces of paper in the end, then who will be willing to do it? You don't have to worry about the cafeteria, but on Gu Xiaomao's side, it is impossible for the teacher to force him, you have to do it yourself;

Thirdly, and most importantly, you have to think about whether someone will copy your credential in the future and use it for profit! Our Yanhuang Academy is not big, but it is not small, if someone forges the certificate, then the loss we suffer should not be underestimated! ”

While listening, Li Ke wrote down all the questions Li Zexuan said in the booklet, and after Li Zexuan said it, he got up silently for a while and said:

"Thank you for your teachings! Regarding the first and second points, the students will try their best to make the merchants of their own colleges believe in this certificate, and as for the third point, the students think that they can stamp the pattern on this certificate, the complex points of the drawing, and then stamp the private seal of the mountain chief, others are afraid that it is not easy to imitate, right? ”

Li Zexuan shook his head and said, "Who said that seals can't be imitated?" However, if you only use this voucher in the college, it is not impossible to do so! But I hope that this kind of transaction voucher can be promoted to the private sector in the future! So, Xiao Ke, you either don't do it, if you want to do it, then do it impeccable! It is difficult for people all over the world to imitate it! ”

Li Ke's eyes widened, and he said incredulously: "Mountain Chief, you...... Do you want ordinary people and businessmen to use this kind of voucher to trade? ”

He would never have thought that Li Zexuan would play so big, if the people could also use his certificate, then wouldn't he create a new type of currency?

Thinking of this, Li Ke's breathing became a little short.

Seeing Li Ke's reaction, Li Zexuan smiled faintly: "Why not?" Remember what I told you two months ago? If you can successfully solve the problem of inconvenient copper coins, then you will create an era and go down in history! If you don't let everyone in the world use this kind of certificate, how can you go down in history? ”
