Tamer: I build my home on the back of Xuanwu

Only when ten layers are printed on one side can a complete pattern be formed, which reduces the chance of being counterfeited.

"Ten engraving blocks form a group, and the production speed can be accelerated." Mu Liang said to himself.

The glass is condensed in the hand, and the same engraving block is copied ten times, connected to each other to form a large engraving block, which can print ten banknotes at a time.

In less than 1 minute, all the 20 yuan engraving blocks were made into a whole set of engraving blocks.

"The next step is to make engravings with a face value of 50 yuan, which can reduce two layers of engravings." After thinking about it, Mu Liang decided to reduce two processes.

The smaller the denomination of banknotes, the fewer processes will be required.

He continued to pick up a pen and draw on the paper, designing patterns of 50 yuan, 20 yuan, ten yuan and one yuan banknotes.

After more than an hour, Mu Liang put down his pen and finished drawing all the patterns of banknotes with different values.

On the 50 yuan banknote, the obverse pattern is a sketch of the highland, and the reverse side is the pattern of the highland palace. The engraving on the front and back is 16 yuan in total.

The 20 yuan banknote has a sketch of a commercial street on the front and a three-color lizard pattern on the back. A total of 12 yuan is engraved on the front and back.

The ten-yuan banknote has a simplified picture of Shanhaiguan on the front and a pattern of the "Xuanwu" Fire Feather Eagle on the back. There are a total of eight engravings on the front and back.

One yuan banknote, the obverse is a sketch of the Hanging Pavilion, and the reverse is a sketch of the Tianmen Tower. There are four engravings on the front and back.

Mu Liang made ten identical blocks out of all the engraving blocks and connected them into a group.

"Let's do this for now, wait until the color-changing pigment is produced, and then try to print a complete set of effects."

Mu Liang sprayed out spider silk from his hand, and bundled the glazed blocks of the same face value.

"A banknote workshop should be established, but it needs a lot of people." He sighed inwardly.

Printing banknotes requires two workers for each process, one is responsible for laying the paper, and the other is responsible for painting paint and adjusting the angle of the paper.

"The exchange rate of the contribution value should be linked to the banknotes." Mu Liang had various ideas in his mind, waiting to be realized.

"Mu Liang."

The study door was pushed open from the outside.

Yue Qinlan walked in with graceful steps.

"What's the matter?" Mu Liang raised his eyes and asked softly.

"Shouldn't ID cards be promoted throughout the city?" Yue Qinlan glanced at the glass engraving next to the wooden table, her eyes revealing curiosity.

"Well, it can be extended to the whole city, and the first census will be completed just before arriving in Wan Yao City." Mu Liang nodded in response.

The census is very important and is beneficial to the management and planning of Xuanwu City.

"Census?" Yue Qinlan blinked her blue eyes.

Mu Liang explained in easy-to-understand words: "It's just counting the number of people."

"I understand." Yue Qinlan suddenly understood.

She decided to arrange for people to come to the door later, and to count everyone's image characteristics, age, etc.

Yue Qinlan pointed to the piles of glass engravings and asked curiously, "Mu Liang, what is this?"

"Master block engraving of banknotes." Mu Liang explained casually.

These engravings will come in handy when the banknote workshop opens.

"Paper money, is the currency you mentioned before, used to replace the contribution value?" Yue Qinlan asked in amazement.

She had heard Mu Liang mention banknotes before, and knew that the contribution value was just a product of excessive effects.

"Yes." The corners of Mu Liang's mouth rose.

"It's finished so quickly." Yueqin Lanhong's lips parted slightly.

The contribution value system has only been perfected soon, and paper money to replace it will be available.

"It's not too soon, it's time for currency reform." Mu Liang said gently.

Although the current 'contribution value system' is perfect, some aspects are still troublesome.

Every time you increase or decrease the contribution value, you need to go to the exchange or a specific place to do it.

Not to mention that it is time-consuming and labor-intensive to go back and forth, and it is not convenient.

The most important thing is that the contribution value is only a number on paper, not a real object, which will reduce the residents' sense of belonging and is easy to be tampered with.

"I don't know as much about these things as you do."

Yue Qinlan spread her hands and said elegantly, "I just need to do my job well."

"Go." Mu Liang laughed dumbly, with tenderness in his black eyes.

Yue Qinlan raised her right hand, shook her slender fingers, and left with graceful steps with a smile on her face.

......

In the research institute, Yuffier is researching color-changing pigments of different colors.

"Mu Liang also wants gold, red, yellow..." She muttered to herself.

In the vessel made of glazed glass in front of her, there is a light golden liquid, which is the color-changing pigment she reconstituted.

"What color can it be this time?"

Yuffier took out a piece of waste paper, dipped a wooden stick in some golden paint, and spread it evenly on the paper.

"Hoohoo~~"

The blond girl puffed her mouth to dry the paint on the paper, and took it under the care of the lantern beetle.

Under the light of the lantern beetle, the golden pigment on the paper changes from gold to aqua blue.

"Ah, it's a success." Yuffier's face showed joy.

The blond girl took the paper away from the light of the lantern beetle, and the water blue turned back to pale gold.

"Very good, keep working hard and make several more colors at once." Yuffier became excited.

She picked up a pen and wrote down the ingredients and production method of the golden color-changing pigment to avoid forgetting.

"Red pigment, I'm thinking about how to make it..." Yuffier blinked her golden eyes and looked around at the various materials in the research institute.

"Try it with tomatoes?"

"No, those are green vegetables, not herbs, so there should be no reaction."

The blond girl walked around the research institute, picked and picked four or five kinds of herbs, and decided to try them slowly.

Time passed slowly, an hour later.

"Bang~~"

There was a muffled sound in the research institute, and thick smoke drifted out.

"Huh? Miss Yuffie?"

Xiaomi who came to deliver the tea was shocked.

She hastily put down the tray in her hand and knocked hard on the door of the institute.

"Knock, knock, knock~~"

"Miss Yuffier, are you alright?" Xiaomi shouted, with an anxious expression on her pretty face.

"Cough cough~~"

In the research institute, Yuffier's face was covered with ashes, and he coughed a few times with difficulty.

She hurriedly shouted: "I'm fine, don't come in."

She was just experimenting with red color-changing pigments, but she didn't expect that she made a mistake and almost blew up the research institute.

Fortunately, the weight used in the experiment is very small, and the power of the explosion is limited.

In addition, the glass vessel is hard enough to suppress most of the explosive power and prevent it from spreading.

Xiaomi froze when she pushed the door, recalling what Wei Youlan said.

Every time before entering the research institute, you must ask Yu Feier for instructions, and don't rush in through the door.

Otherwise, if you inhale some unknown gas, you may die miserably.

"Do you need someone to help?" Xiaomi asked hastily.

"No, you can come in after the smell dissipates." Yuffier responded.

She clapped her hands, dropped the stirring stick that was half blown away, and turned around to open the ventilation window to let the gas produced by the explosion out of the institute.

"¨〃 I have to tell the Lord City Master." Xiaomi kept it in mind.

After more than ten minutes, all the gas in the research institute was exhausted.

The star tea tree automatically evolves and decomposes the toxic substances in the air without wind.

crunch~~

The door was pushed open, and Xiaomi walked into the institute covering her mouth and nose.

When she saw the blond girl covered in ashes, she felt a little embarrassed.

"It's okay, you don't need to cover your mouth." Yuffier raised her hand and wiped her face, leaving five finger marks.

"Really?" Xiaomi was still worried.

"Really." Yuffier said indifferently.

She reached out to pick up the teacup, filled the cup of tea in one breath, and refreshed her mind.

"Let me tidy up the institute for you." Xiaomi said as she was about to put down the tray.

Yu Feier waved her hand, Jiaohan refused, "No, some of it is poison, you'd better not touch it."

"...Okay." Xiaomi withdrew her hand, feeling terrified in her heart, the research institute is really too dangerous.

"Okay, you go back, I'm going to continue my research." Yuffie put down the teacup.

After drinking the star tea, she suddenly had a new idea, and once again put herself into the experiment in high spirits.

"Then I'll go first." Xiaomi took away the teacup and the lunch box delivered at noon.

She closed the door of the research institute, left quickly, and walked to the high ground.

Five or six minutes later, Xiaomi returned to the palace, put down the tray and lunch box, and came to the door of the study.

"Xiao Mi, what's the matter?" Buff, who was guarding the study door, asked suspiciously.

"I want to find the Lord City Master." Xiaomi said seriously with a small face.

Buff didn't ask much, and turned sideways.

knock knock knock

"My lord." Xiaomi knocked on the study door.

"Come in." A voice answered from the room.

"My lord." Xiaomi pushed open the door of the study and entered.

When she saw Mu Liang, she subconsciously stepped lightly, stood one meter in front of the desk, lowered her eyes and saluted respectfully.

"What's the matter?" Mu Liang raised his eyes and asked calmly.

"I just went to deliver tea to Miss Yuffier..." Xiaomi described the process one by one.

She said with a worried face: "I'm a little worried, so I told the Lord City Lord."

"Is she okay?" Mu Liang frowned.

Xiaomi hesitated for a moment, then responded: "It looks fine, before I left, Miss Uffier was still doing research."

"I see." Mu Liang nodded slowly.

Yuffier can continue to do experiments, which means there is no serious problem.

It's just that experimental accidents don't happen just once, they have to be prevented.

With a plan in mind, he raised his eyes and praised: "You did a good job."
