Tamer: I build my home on the back of Xuanwu

The toughness and strength of the evolved spider silk have increased several times.

"Well, only such spider silk can be made into explosion-proof clothing." Mu Liang was satisfied.

He is going back to the studio to process spider silk and make explosion-proof suits.

"Master Mu Liang, Miss You Fei'er, please go over there." Wei Youlan came back from the research institute.

She just brought tea and clean clothes to Yuffier.

The blond girl stayed in the research institute day and night, and the changed clothes would be collected by the little maid at 25.

Wait until it is cleaned and dried before sending it back.

"What's the matter?" Mu Liang paused.

"It seems that the research on pigments has achieved results." Wei Youlan said uncertainly.

"Color-changing paint!" Mu Liang was shocked.

Using his ability, he jumped up lightly, and when he fell again, he was already at the entrance of the research institute.

"Crunch~~"

Pushing open the door, Mu Liang and You Feier looked at each other.

The blond girl blinked her golden eyes, and the original confusion disappeared.

She quickly lowered her head, not daring to keep looking at Mu Liang, her pretty face was blushing.

Mu Liang smiled and asked softly, "Has the paint progressed?"

"Mu Liang, I have researched the color-changing pigment." You Feier raised her head and said excitedly.

She gestured to the workbench behind her. There were five glass jars on it, and the liquids in them were of different colors.

Gold, red, yellow, blue and gray.

"Can it change color?" Mu Liang stepped forward and picked up the glass jar filled with red paint.

Yuffier nodded vigorously: "Yes, the red pigment can turn green under the light of the lantern beetle."

"Try." Mu Liang opened the glass jar.

Yuffier quickly handed over a glass stick for stirring.

Mu Liang dipped some red paint with a glass stick, and placed it under the light of the lantern beetle, the bright red really turned into emerald green.

He tried gold and other colors in turn, and they all turned into other colors under the light.

Gold turns aqua blue in light, blue turns purple, yellow turns green, and gray turns pure black.

"Very good, now we have all the materials for making banknotes." The corners of Mu Liang's lips turned up, excited.

"Are these colors enough?" Yuffier asked softly.

"Well, that's enough for now."

Mu Liang nodded in satisfaction, and praised: "You did a good job."

"I'm very happy to be able to help Mu Liang." You Fei'er looked away, still not daring to meet Mu Liang's eyes.

"It was a great help." Mu Liang smiled brightly.

Yuffier quickly took out the prepared materials, handed them over and said, "Here are the production methods and material ratios of the five color-changing pigments."

"Are the materials for making these paints easy to obtain?" Mu Liang put away the formula of the color-changing paint.

Yuffier said delicately: "Except for the leaves of the Star Tea Tree, the others are all made from common medicinal herbs."

Mu Liang asked again: "Will it be troublesome to mass-produce these kinds of color-changing pigments?"

"It's not troublesome, but it takes a certain amount of time to wait for the drugs to react with each other." Yuffier said delicately.

Mu Liang said gently: "I will set up a new workshop, and then you can teach the staff to learn how to mix color-changing pigments."

It's time to open a banknote workshop. There are ready-made houses, and the only thing is to recruit staff.

All staff need to sign the queen bee contract to ensure that the method of making banknotes will not be leaked.

"No problem." Yuffier nodded her head repeatedly.

"Okay, now you should go to rest for a while." Mu Liang raised his hand and rubbed the blond girl's head.

She looked dazed, as if she was about to fall asleep, and there were dark circles under her eyes.

"I want to sleep for a while." Yuffier's pretty face flushed again, and she couldn't bear to lower her head.

"Okay, I'm leaving first. I'll let Xiaolan call you after the workshop recruits all the staff." Mu Liang said softly.

"All right."

Yu Feier's golden eyes were filled with reluctance, and she waved her small hand to send Mu Liang away.

…………

Mu Liang left the research institute and returned to the studio with the color-changing paint.

He put down the five cans of color-changing paint and found the No. [-] paper sent by the paper workshop.

No. [-] paper is special paper for banknotes made from the leaves of the star tea tree.

Knock Knock~~

There was a knock on the study door.

Li Yue pushed open the door and came in. She had just delivered the soil and fertilizer materials to Yue Qinlan.

"Mu Liang, what are you doing?" She asked in surprise.

"Make banknotes." Mu Liang explained with a smile.

"Do you need help?" Li Yue asked softly.

She knows what paper money means, that is a new transaction currency, replacing the existence of contribution value.

"Not for now." Mu Liang shook his head.

He took out the engraving block that he had made in advance, placed it on the wooden table, brushed the paint evenly on the engraving block, then covered it with No. [-] paper, and pressed it firmly firmly.

Li Yue leaned forward and saw Mu Liang flipping the paper away, and there were red patterns on the off-white paper.

Mu Liang changed another engraving block, and at the same time changed another color, and covered the front and back of No. [-] paper again.

Liyue was amazed to see that Mu Liang changed the engraving blocks for a total of 20 yuan before and after, and used five kinds of pigments repeatedly for many times.

The off-white paper has many colors on the front and back.

"Okay." Mu Liang put down the last engraving block, and lifted the No. [-] paper off it.

He shook the paper lightly, and the paint on it dried quickly without smearing to the outside of the paper.

"The effect is surprisingly good." The corners of Mu Liang's mouth rose.

There are ten banknote patterns printed on the No. [-] paper, which are of a face value of [-] yuan.

Printed with a rock turtle on the front and a star tea tree on the back.

The pattern of rock turtles is mainly gray, supplemented by the other four colors.

The pattern of the star tea tree is based on green and yellow as the main colors, and the other three colors are auxiliary colors.

The number 100 is printed on the lower left and upper right corners of the banknote.

Mu Liang picked up a knife and cut out ten hundred-yuan banknotes. They were the same size, with only slight differences in color shading.

"Look, does it look good?" Mu Liang handed one of them to the white-haired girl.

"It's beautiful, like a work of art."

Liyue's white eyes were shining brightly, carefully observing the patterns and patterns on the banknotes, she couldn't put it down.

She touched the banknote carefully, and found that the pattern on the banknote had a slight concave and convex I feeling.

"Mu Liang, why is the pattern raised?" Li Yue asked curiously.

"It's for anti-counterfeiting." Mu Liang explained.

The raised pattern on the banknote is specially made after ten layers of paint are superimposed on one side.

"So that's the case." Li Yue nodded slowly.

Mu Liang reminded: "You put the banknotes under the light of the lantern beetle before looking at them."

Liyue couldn't help being curious, so she did.

Under the bright light, the hundred-yuan banknote changed, and Mu Liang's head appeared under the original pattern of the rock-shell turtle.

"Huh?" Li Yuemei's eyes widened, and she quickly turned to look at Mu Liang.

"That's the second layer of anti-counterfeiting label." Mu Liang explained with a smile.

This is the characteristic of color-changing pigments. Different pigments are superimposed, and after Mu Liang's layer design, his appearance is finally formed, which can only be seen under the light.

"Good design." Li Yue praised.

There was a trace of curiosity in her heart, how did Mu Liang come up with such a clever plan?

Liyue suppressed her curiosity and continued to look at the hundred yuan notes.

The paper originally had irregular textures, which were formed after the leaves of the Xingchen tea tree were made into paper.

"Do you want to try how to print banknotes?" Mu Liang asked softly.

He wrote down the color used for each stencil to avoid the staff using the wrong color in the banknote workshop.

"Can I do 560?" Li Yue was eager to try.

"Of course, you can try to make banknotes with a face value of 50 yuan." Mu Liang took out another set of glazed engraving plates and placed them on the wooden table.

Liyue picked up the paint brush, which was made of spider silk.

"Mu Liang, what color is the first layer?" She asked nervously.

Mu Liang glanced at the carving and said, "Use yellow."

"Okay." Li Yue replied.

She dipped a little yellow paint with a spider silk brush, and gently brushed on the first engraving, carefully brushing every corner.

Mu Liang watched quietly, and found that this was also a kind of enjoyment.

Liyue's long eyelashes trembled, and she asked softly, "Is this all right?"

Mu Liang said in a clear voice, "Well, put the No. [-] paper on it and press it tightly."

"Okay." Liyue put down the spider silk brush, picked up a new No. [-] paper, and carefully covered it on the engraving block.

She then gently pressed tightly with her hands, not letting go of every corner.

"According to the order, this is the second engraving block, with red paint." Mu Liang signaled.

"Okay." Li Yue put on a pretty face, her expression focused.

The production of 50 yuan banknotes requires a total of 16 yuan engraving on both sides, which is not easy.

After 10 minutes, a set of block printing is completed, and ten banknotes can be obtained, which is not very efficient.

Mu Liang frowned, thinking that he should make a few more sets of engraving blocks and recruit more workers to improve efficiency.

Or design a mold cover, so that you don't have to align the printed lines.

"Mu Liang, how are you?" Li Yue handed over the printed 50 yuan notes as if offering a treasure.

Mu Liang checked carefully, and there was no problem with anti-counterfeiting patterns and watermarked portraits.

He sincerely praised: "Well, very good."

With a smile on her face, Li Yue cut off ten banknotes with a knife.

Mu Liang smiled lightly and asked, "Will you try making 20 yuan banknotes again?"

"Okay." Li Yue nodded enthusiastically, losing some of her usual cold look.

Both of them stayed in the study all morning, researching and making banknotes of different denominations.
