Trainer: I Build My Home on the Back of Xuanwu

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

"As a group of ten engravings, the production speed can be faster." Mu Liang muttered to himself.

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

In less than a minute, the twenty engraving plates were all made into a whole set of engraving plates.

"The next step is to make an engraving plate with a face value of fifty yuan, which can reduce two layers of engraving plates." After thinking, Mu Liang decided to reduce two processes.

The smaller the denomination of the banknotes, the less work there will be.

He continued to pick up the pen and draw on the paper, designing the denominations of fifty-, twenty-, ten-, and one-dollar bills.

More than an hour later, Mu Liang put down his pen and finished drawing all the banknotes with different values.

The 50-yuan banknote has a sketch of the Highland on the front and the palace of the Highland on the reverse. There are sixteen pieces of engraving on the front and back.

The 20-yuan banknote has a sketch of a commercial street on the front and a tri-colored lizard on the reverse. There are twelve engravings on the front and back.

The ten-yuan banknote has a sketch of Shanhaiguan on the front and a pattern of the 'Xuanwu' Fire Feather Eagle on the reverse. There are eight engravings on the front and back.

The one-yuan banknote has a sketch of Hanging Pavilion on the front and a sketch of Tianmen Tower on the reverse. There are four engravings on the front and back.

Mu Liang copied all the engraving blocks out of the same ten pieces and connected them into a group.

"Let's do this for now, wait for the color-changing paint to be made, and then try to print a whole set of effects."

Mu Liang sprayed spider silk from his hand, and bundled the glass engraving plates of the same denomination into groups.

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

To print banknotes, two workers are required for each process, one is responsible for laying the paper, and the other is responsible for painting the paint and adjusting the angle of the paper.

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

"Is the ID card supposed to be promoted in the whole city?" Yue Qinlan glanced at the glass engraving beside the wooden table with curiosity.

"Well, it can be extended to the whole city. Just before arriving at Ten Thousand Demons City, the first population census will be completed." 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 was stunned.

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

Yue Qinlan pointed at the piles of glass engraving plates and asked curiously, "Mu Liang, what is this?"

"The master engraving of the banknotes." Mu Liang explained casually.

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

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

She had heard Mu Liang mention paper money before, and knew that the contribution value was just a product of overuse.

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

"It's done so soon." Yueqin's blue and red lips parted slightly.

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

"Sorry, it's time for currency reform." Mu Liang said mildly.

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.

This is time-consuming, laborious, and inconvenient.

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

"I don't know as much as you do."

Yue Qinlan spread her hands and said elegantly, "I just need to do my share of work."

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

Yue Qinlan raised her right hand, shook her slender fingers, smiled and left with graceful steps.

......

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

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

In the vessel made of colored glass in front of her, there was a pale golden liquid, which was the color-changing paint she re-mixed.

"What color can it be this time?"

Yuffie took out a piece of waste paper, dipped a wooden stick with some golden paint, and evenly smeared it on the paper.

Section 250

"Hoohoo~~"

The blond girl puffed out her mouth to dry the paint on the paper, before taking it under the lantern beetle to look after it.

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

"Ah, it's successful." Yuffie's face beamed with joy.

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

"Very good, keep working hard and make several other colors in one breath." Yuffie became excited.

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

"Red paint, I think about how to make it..." Yuffie blinked her golden eyes and looked around the various materials in the research institute.

"Try it with tomatoes?"

"No, those are green vegetables, not herbs, so they shouldn't react."

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

Time passed slowly, an hour later.

"Bang~~"

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

"Huh? Miss Yuffie?"

Xiaomi, who came to deliver tea, was taken aback.

She quickly put down the tray in her hand and knocked on the door of the research institute.

"Knock knock knock ~"

"Miss Yuffie, are you alright?" Xiaomi shouted loudly, with an anxious look on her pretty face.

"cough cough~~"

In the research institute, Yuffie's face was gray, and she coughed a few times.

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

She was just experimenting with red color-changing pigments, but she didn't expect an operation error that almost blew up the institute.

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

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

Xiaomi's movement of pushing the door froze, recalling what Wei Youlan said.

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

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

"Need someone to help?" Xiaomi asked hurriedly.

"No, wait until the smell dissipates before you come in." Yuffie responded.

She clapped her hands, dropped the half-blown stirring stick, turned to open the ventilation window, and let the gas from the explosion escape the institute.

"¨〃You have to talk to the Lord of the City." Xiaomi took it to heart.

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 research institute with her mouth and nose covered.

At a glance, she saw the blonde girl covered in gray, a little embarrassed.

"It's alright, don't cover your mouth." Yuffie raised her hand and wiped her face, leaving five finger marks.

"Really?" Xiaomi was still worried.

"Really." Yuffie said indifferently.

She reached out and picked up the teacup, suffocating the whole cup of tea in one breath, refreshing her mind.

"Let me organize the research institute for you." Xiaomi said, and was about to put down the tray.

Yuffie waved her hand, but Jiaohan refused: "No, there are some poisons in it, you'd better stay still."

"...Okay." Xiaomi shrank her hands, she was terrified, the research institute was too dangerous.

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

After drinking Xingchen tea, she suddenly had a new idea, and she went into the experiment again 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.

"Xiaomi, what's the matter?" Buff, who was standing at the door of the study, asked suspiciously.

"I'm looking for Lord City Lord." Xiaomi said seriously with a small face.

Buff didn't ask much, and turned sideways.

knock knock knock

"Lord City Lord." Xiaomi knocked on the study door.

"Come in." A voice of agreement came from the room.

"Lord City Lord." Xiaomi pushed open the door of the study and entered.

When she saw Mu Liang, she subconsciously stepped down, 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 Yuffie..." Xiaomi described the process in 1510.

She said with a worried face: "I'm a little worried, so let's talk to the Lord of the City."

"Is she okay?" Mu Liang frowned.

Xiaomi hesitated for a while, then responded: "It looks fine. Before I left, Miss Yuffie was still doing her research."

"I see." Mu Liang nodded slowly.

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

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

He had a plan in his heart, raised his eyes and praised: "You did a good job."
