Professor Gu Luo Tu hadn't laughed for a long time, but when he saw a banknote made by Jian Xun Lou, he couldn't help laughing, because it was a banknote of one or two denominations, Professor Gu Luo Tu had never seen such a unit of measurement, and he had never seen such a counting unit, and the front of the key banknote was still a photo of Jian Xun Lou himself.

"Do you want to be emperor?" Professor Gu Luotu has some understanding of the history of the Ming Dynasty, and this is the first time he has said a digression to Jian Xunlou in the past few months.

Chongzhen Emperor Zhu Youzhen saw Professor Gu Luo Tu smiling, but he didn't laugh, he felt Professor Gu Luo Tu's hostility towards him, Professor Gu Luo Tu was afraid that he would take Yan Ting to the underworld, but he had officially entered the underworld! And it's also the core layer of the underworld! The real yàn room where he is now is the highest-level real yàn room that the underworld characters in the world can master!

"I don't want to be an emperor, if there is one person in the world who doesn't want to be an emperor, then this person can only be me! I'm just using my own avatar to practice my skills, and this avatar was taken when I used to have fun. Chongzhen Emperor Zhu Youzhen said lightly. In fact, this photo of the yellow robe was taken when he was in the Ming Dynasty, and he had long been preparing for coming to the modern zuò money printing machine!

Professor Gu Luotu nodded, and looked at it with a set of banknotes made by the inspection of Xun Building! "Yes, I can tell you that this is already the most advanced banknote in this era, and you have used all of the more than 20 anti-counterfeiting technologies! Good! It's not in vain that I put my mind to it, in the future, if you imitate any kind of banknote, you will be able to confuse the real thing! ”

Chongzhen Emperor Zhu Youzhen's face was still expressionless, he didn't know how long he had been here! This real yàn room of his. It is equivalent to already being part of his Daming Central Bank! The Central Bank of Daming issued the first set of Daming coins. There are 10 cents and 50 cents. 100 cents, 1 tael of silver, 5 taels of silver, 10 taels of silver, 100 taels of silver, 1,000 taels of silver, a total of 9 denominations, of which 1 cent, 10 cents, and 50 taels have two kinds of banknotes and coins. Stainless steel, steel white in color.

The first set of Da Ming coins inherited the traditional experience of Chinese printing technology, borrowed from the advanced technology of foreign banknote design, and greatly improved the anti-counterfeiting performance and adaptation to the modernization of currency processing. The front of each denomination currency adopts the head of Chongzhen Emperor Zhu Youzhen when he ascended the throne, the bottom lining adopts the famous Chinese flower pattern, and the main scene pattern on the back is selected Wumen and Jiangxi Lushan respectively. Guilin landscape, Chengtianmen, Mount Tai, Hangzhou West Lake. Tongguò selects representative patterns with national characteristics, which fully expresses the long history and magnificent mountains and rivers of our great motherland, and promotes the great national culture.

2. Safety line: The first set of Daming coins (except for one yuan) has a safety line on the left side of the front of the coupon face.

3. Photovariable ink: The denomination numbers on the lower left of the front of the first set of Daming coupons of 100 yuan and 50 yuan coupons are printed with photovariable ink. When tilting the face of the ticket vertically to a certain angle, the denomination number of the 100 yuan coupon will change from green to blue; The denomination of the $50 coupon will change from gold to green.

4. Yin and Yang Complementary Printing Pattern: The first set of Yin and Yang complementary printing patterns of Daming banknotes are used in 100 yuan, 50 yuan, 10 yuan and 05 version of 20 yuan coupons. The three tickets are printed with a circular local pattern on the lower left of the front and the bottom right of the back. In the light perspective, the two patterns are accurately docked and combined into a complete ancient coin pattern.

5. Observe the face of the ticket with a magnifying glass of more than 5 times to see whether the pattern lines and microtext are clear and clean. The first set of Daming banknotes are offset printed on the front of each coupon. Microtext is printed in many places.

6. White watermark: The first set of Daming coins is located below the horizontal number on the obverse, which is visible to the light. You can see the denomination watermark with strong light transmission.

7. Invisible denomination number: There is a decorative pattern in the upper right corner of the front, which is placed in a position close to parallel to the eye, and tilts up and down in the face of the light source, and the denomination number can be seen.

Touch the portrait, braille dots, the name of the central bank of the Ming Dynasty, etc.

Gravure feel line: On the right side of the main scene pattern on the front of the first set of Daming coins of each denomination, there is a group of lines arranged regularly from top to bottom, which is printed by engraving gravure printing process, and touches it with your fingers, with a strong sense of concave and convex.

That is, the banknote is shaken to make a sound, and the authenticity of the Ming coin is distinguished according to the sound. The paper of the Daming coin has the characteristics of crispness, folding resistance, and not easy to tear. Shake the banknote vigorously, flick your fingers, or pull gently and symmetrically with both hands, and you can hear a crisp and loud sound.

That is, with the help of some simple tools and special instruments to distinguish the authenticity of the Ming coin. For example, with the help of a magnifying glass, you can observe the clarity of the lines on the ticket, glue, gravure microtext, etc.; By irradiating the face of the bill with ultraviolet light, the fluorescent reflection of the banknote paper and ink can be observed; The magnetic detector can be used to detect the magnetism of black horizontal numbers.

This set of Daming banknotes, paid a lot of effort by Emperor Zhu Youzhen, from every part, from every idea, he completed it independently, in fact, there is no machinery that can stump him! If there is time, Emperor Chongzhen Zhu Youzhen can copy all the simple machinery of modern times to the Ming Dynasty!

"Am I qualified for the technology of the money printing machine?" Chongzhen Emperor Zhu Youzhen asked.

Professor Gu Luo Tu nodded, "It's qualified, and it's even surpassed me!" You are very talented! Making zuò powder, you also learn, you can produce the highest purity powder! You have all the technology to create bomber high-explosive bombs, but all this equipment is in the jungles of Mexico! I don't have a complete set of equipment here for you to produce large-scale! The eighteen bomber high-explosive bombs you made are all qualified! You can go out and rest for a while today, and you've completed the first phase of your course. ”

Listening to Professor Gu Luotu's talk about these underworld techniques as if they were in a university, Chongzhen Emperor Zhu Youzhen didn't know what his feelings were, and nodded, "How long have I been here?" ”

It is a constant temperature here, and there is no contact with the outside world, and Emperor Zhu Youzhen of Chongzhen does not know how long it has been.

Professor Gu Luotu calculated, "It's been a whole year and three months. (To be continued......)
