Fang Xuanling and others discussed for a long time that Datang Bank began to speed up its operation as Li Su brought people back to Chang'an City.

A steam-powered printing press is ready in a newly built workshop to be used as a prison.

Some workers in the workshop were transporting stacks of special paper to the printing press under the command of Li Su.

Yan Lide took someone to carefully inspect the printing machine again, and confirmed that there would be no problems with every part.

When everything was ready, Li Su came to Li Shimin and said, "Please ask my father to order the printing to begin." ”

After Li Shimin heard Li Su's words, his eyes moved away from the huge printing press and looked at Fang Xuanling and the others who followed.

At this time, everyone's eyes still revealed a look of shock.

It was the first time they had witnessed such an advanced automaton.

The boiler of the steam engine was spewing puffs of white smoke.

This is the water vapor formed when the cup of water inside is boiled.

It is released from the vent hole in order to maintain a fixed pressure.

The parts used in the entire machine are made of steel, polished and painted.

At this time, everyone did not know how the behemoth in front of them was going to operate.

Therefore, seeing Li Shimin's gaze, it seemed that he immediately showed a look of excitement and anticipation.

Seeing this, Li Shimin said to Li Su: "Then let's start." ”

After Li Su heard this, he immediately waved his hand to Yan Lide.

I saw Yan Lide personally open the valve to release steam.

With a "bang" sound, the huge gearing began to kick in slowly.

Then the speed of rotation gradually increased, and after only a few breaths, the template moved up and down.

Li asked the worker to bring an ordinary piece of white paper and put it on a short conveyor belt in front of the template.

As the rubber belt rolled forward, the white sheet of paper was quickly sent underneath the template.

As the template fell and was quickly lifted, the white paper was printed with exquisite patterns.

Next, the baffle in front of the template is lowered, and the paper is moved towards the other template under the drive of the rollers.

Two workers carefully turn the paper over, and the press repeats the same action.

After all the two sides were printed, Li Su came to the paper and examined it carefully.

He examined it very carefully, and in addition to his normal visual vision, he touched the pattern with his hand.

Then Li Su took out a magnifying glass and took a closer look.

After a while, Li Yu exhaled softly, and then nodded happily at Yan Lide.

After Yan Lide received the message, he immediately asked someone to bring a real banknote paper and repeated the operation just now.

But this time, after reading it, Li Su put the paper on the conveyor belt again.

There are two more cutting processes in the back.

After everything was over, the banknotes were quickly sorted out and sent to Li Shimin and others.

Li Shimin reached out and picked up one and looked at it carefully.

The banknote is about six inches long and more than two inches wide.

Some of the front to the right is the head of the Emperor Li Yuan, and the whole head is vividly depicted.

In the portrait, Li Yuan looks straight into the distance with a smile on his face, and the beard under his chin seems to be fluttering in the wind.

The banknote is printed with the word "One Hundred Yuan", and the pattern is reflected at the bottom of the font.

The upper edge is printed with the words Datang Bank, and there are two Arabic numerals around the ring, and the word 100 is written in Arabic numerals.

There are also a variety of light and dark patterns and a string of numeric numbers.

The reverse side is printed with the shape of the Jinluan Hall of the Tang Dynasty, with various hundred yuan characters on all sides, and several other common foreign characters.

The overall color of the banknote is slightly golden, with some other colors interspersed to set it off.

An engraving craftsman stood next to Li Shimin and whispered several anti-counterfeiting traces on the banknote.

Li Shimin tried to grope with his fingers, and immediately showed a satisfied look on his face.

While Li Shimin was inspecting the note, workers were also changing stencils and cartridges to print the next denomination.

Li Shimin said with emotion while motioning to take the banknotes to Fang Xuanling and others for circulation: "I can't imagine that my Datang Technology has reached such a height. ”

Fang Xuanling said while groping for the banknotes in his hand: "With such an exquisite process, I'm afraid that no other country can master it except Datang." ”

The eldest grandson Wuji said: "With this artifact in hand, the imperial court no longer needs to worry about the difficulty of minting copper coins. ”

Wang Qi said: "With paper money, Datang can completely end the barter transaction, so that Datang's commercial development will become more and more prosperous." ”

The second type of banknote was also printed.

The denomination of this one is fifty yuan, the front is a pattern of five scholars, and the reverse side is the Yangtze River, the largest water source in the Tang Dynasty, and the face color is purple.

Except that the size of the ticket is slightly smaller, there is no difference in the process.

Soon all other denominations were printed.

The face value of ten yuan, the front pattern is ten farmers, and the reverse pattern is the Yellow River, the largest river in the Tang Dynasty, and the face color is light cyan.

One yuan denomination, the front pattern rice, millet, millet and other staple grains, the reverse pattern is a piece of farmland, the face color of the ticket is green.

Five corners, the front pattern is a team of sergeants, the reverse pattern is Chang'an City, and the face color is earthy yellow.

The remaining two faces are two corners and one corner.

The obverse motifs used are the armillary sphere and the Taiji hall, respectively.

The reverse side depicts two different landscape paintings.

In addition to printing banknotes, it is also responsible for printing bankbooks.

The passbook is made of the same paper as the bookbook, but after printing, it also has an additional security mark.

After looking at all the banknote samples, everyone left the prison with excitement.

The place will then be heavily guarded, and everyone who enters or leaves here will be subject to the strictest checks.

Construction of a huge single-story building in the east market of Chang'an City has been completed.

After the first batch of banknotes is printed, it will be ready for business.

The various business operations of the bank have been printed on the notices, and the street envoys under the jurisdiction of the left and right Jin Wuwei have personally posted them on the main streets of Chang'an City.

Li Zhe of Jingzhao Mansion specially arranged for people to stand next to the notice to answer the people's questions.

As the publicity work continued, the people of Chang'an City began to take an interest in this new industry.

Especially when people hear that they can still charge interest every year when they keep the surplus money in their hands in the bank, they can't help but be amazed.

They only knew that they had to pay interest on borrowing money, but it was the first time they had heard that they would pay interest on keeping money for others.

However, when the people heard that the coins issued were actually made of paper, they were all shocked and puzzled.

It was shocking that the imperial court could actually think of using paper to make coins.

The question is how paper is so fragile and can it be used for a long time.
