Otaku Engineer in Great Tang Dynasty

? Create an era, stay in history!

At this time, Li Ke realized that what Li Zexuan said to him was not bragging, but something that could happen!

But, can he really make all the people of Datang use the transaction vouchers he created?

Li Ke couldn't help but have a trace of doubt in his heart!

Seeing Li Ke's expression of suspicion, Li Zexuan patted his shoulder and said, "Xiao Ke, don't think about it so much. Right now, your first task is to convince everyone in the college to believe in your transaction voucher, and make sure that you are this transaction voucher. It will not be imitated by others! As for all the people in Datang willing to use our transaction voucher, it is still early, we still have a long way to go!"

"Then Shanchang, what should I do so that the transaction voucher cannot be imitated?"

Li Ke asked with bright eyes.

Li Zexuan smiled mysteriously and said: "Three days later, you go down the mountain and go to the workshop. Fu Bo will give you a transaction voucher printed by the workshop. Then you will know that there are indeed some things in this world that are difficult to remember. Imitation!"

Li Ke was pleasantly surprised: "Shanchang, you already have a solution~?"

"Haha! Be it! Three days later, I'll see it!"

Li Ke saw that Li Zexuan didn’t want to go into details, so he didn’t continue to ask. At this moment, he felt that something was still missing. After thinking for a while, he said: "Shan Chang, the students feel that we have to give this transaction certificate a name and design it. It's easy to make a different one, so it's easy to use in the future!"

Li Zexuan nodded. Without Li Ke's words, he would also name the banknote, but what name should it be? Renminbi or silver bills? Forget it, this is a bit different from the Tang Dynasty!

After thinking for a long time, Li Zexuan finally spoke:

"Let’s call it Tang Yuan! One Tang Yuan is equal to the consistent money, and there are Tang horns under Tang Yuan, and one Tang horn is equal to one penny! As for the face value of the voucher, there can be one Tang horn, five Tang horns, ten Tang horns, and fifty Tang horns. Jiao, one hundred Tang Jiao, and one Tang Yuan, Five Tang Yuan, Ten Tang Yuan, Fifty Tang Yuan, One Hundred Tang Yuan! When trading, regardless of the value of the item, it can be combined with glutinous rice **** of different denominations. The corresponding amount of money is convenient and time-saving!"

"Tang Yuan? This name sounds good!"

Li Ke's eyes lit up, he admired and said, "Shan Chang, what is the name of the department that specializes in depositing and withdrawing Tang yuan from students or merchants?"

I have to say that this child is quite thoughtful about the question.

"Let's call it Yanhuang Bank! The Zhuangzi who specializes in managing the copper coins of Yanhuang Academy!"

Banks are too far away from this era. If you put it up rashly, it's probably hard to be accepted. After thinking about it, there is only the term bank, which makes it easier for people to understand!

"The bank! Good! Then Ke will go to prepare the bank!"

Li Ke got up excitedly and said goodbye.

"Heh! At last there is no waiting in vain, the era of paper money is finally coming!"

After Li Ke left, Li Zexuan's mouth turned into a smile and said to himself.

……………………………

"Hey? No! How do I feel that Shan Chang has already thought of this price method?"

On the way back to the classroom, Li Ke suddenly stopped, beat his head with some annoyance, and whispered in a low voice.

How he doubted it was not without reason.

Just now Li Zexuan, after hearing about his transaction voucher method, seemed to have a perfect anti-counterfeiting plan in his mind. The reason why he said so much was probably just testing him.

However, since Li Zexuan had thought of this method for a long time, why didn't he act until he pushed it?

"Forget it! Don't care about him! The head of the mountain must have his reason!"

After thinking about it for a long time, Li Ke didn't want to understand the meaning of Li Zexuan's doing this, so he shook his head, and simply stopped thinking about it. Right now he still has a lot of things to do!

………………………

"Master Liu, look at this seal, can it be engraved!"

In the afternoon, Li Zexuan took a drawing and came to the workshop to find the Heavenly Sword-Liu Dingyi, who was the housekeeper Liu Yidao, the predecessor of the Qiqu Pavilion, Tiangong Pavilion, with one hand carving technique that is unique in Chang'an, Li Zexuan After buying the Tiangong Pavilion and establishing the Qiqu Pavilion, Liu Yidao was also hired to the workshop for preferential treatment.

At the time when the workshop promoted movable type printing, most of the characters were carved by Liu Yidao,

"Yo~! Hou Yerong takes a look first!"

Liu Yidao didn't dare to neglect, and quickly took the drawing in Li Zexuan's hands with both hands, and began to look at it carefully. After a while, he raised his head and asked: "Hou Ye wants to engrave all these more than one hundred characters on the seal. on?"

"Yes! I don't know where there are difficulties~?"

Li Zexuan nodded and responded.

Mini carving, this craft has a long history, and many skilled craftsmen in the Spring and Autumn Period can do it.

Li Zexuan asked Liu Yidao to make this kind of seal, the main purpose of which was to prevent counterfeiting of banknotes.

In the Song Dynasty, silver tickets appeared in our country. Not only did silver tickets appear, but also many anti-counterfeiting technologies. After all, there were no advanced black technologies such as currency detectors and scan code payments in ancient times. Some of the anti-counterfeiting technologies used are equally good, and Li Zexuan now plans to use one of them, namely the anti-counterfeiting seal!

Previously, Li Ke said that the coin should be stamped with his private seal for anti-counterfeiting, but Li Zexuan felt that it was unreliable because it was too easy to fake a private seal.

This is a kind of anti-counterfeiting method that Shanxi merchants came up with during the Ming and Qing Dynasties. They specially designed a micro-engraved chapter. The content of the micro-engraved chapter is a poem of hundreds of words. Yes, even if it can be made, it will take a lot of material resources and a high level of carving is required to make it.

In addition, during the engraving process, a few words are usually deliberately engraved. Even the original engraver can no longer engrave the same micro-engraving chapter, so the counterfeiter simply gave up making fake tickets.

"Master Hou! This kind of fine carving work, if left a few years ago, Lao Liu, I would still be able to do it, but now my Lao Liu's eyes are very ugly to see small things~www.ltnovel.com ~Your seal, I'm afraid I won't be able to engrave it!"

Old Liu frowned, embarrassed.

When Li Zexuan heard this, he thought: Isn't this just presbyopia? Easy to handle!

"Haha! Master Liu must not rush to refuse, Benhou has a way to let you see the very small things clearly! Wait for a while, and I will send you something tomorrow. Put it on and you can see clearly Everything!"

Li Zexuan said with a smile.

Just kidding, he has built astronomical telescopes, how can he not get a pair of reading glasses? Even if the reading glasses can't be found in a short time, it is always okay to get a magnifying glass first?
