Trainer: I Build My Home on the Back of Xuanwu

The evolved spider silk has increased its toughness and strength several times.

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

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

"Ms. Muliang, Miss Yuffie, please come over." Wei Youlan came back from the research institute.

She had just brought tea and laundry to Yuffie.

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

Return it after cleaning and drying.

"What's the matter?" Mu Liang's footsteps stopped.

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

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

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

"crunch~~"

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

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

She hurriedly lowered her head, not daring to continue to look at Mu Liang, her pretty face flushed crimson.

Mu Liang smiled and asked softly, "Is the paint progressing?"

"Mu Liang, I have researched the color-changing paint." Yuffie raised her head and said excitedly.

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

Gold, red, yellow, blue and grey.

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

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

"Try it." Mu Liang opened the glass jar.

Yuffie hurriedly handed over a small glass rod for stirring.

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

He tried gold and other colors in turn, and under the light, he could turn into other colors.

Gold turns aqua blue in the light, blue turns violet, yellow turns green, and grey turns pure black.

"Very good, the materials for making banknotes are complete now." The corners of Mu Liang's mouth rose, his spirits excited.

"Are these colors enough?" Yuffie 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." Yuffie's eyes dodged, but she still didn't dare to look at Mu Liang.

"It's been a big help." Mu Liang smiled brightly.

Yuffie hurriedly took out the sorted documents, handed them over and said, "This is the production method and material ratio of the five color-changing pigments."

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

Yuffie said coquettishly, "Except for the leaves of the star tea tree, the others are also prepared with common medicinal herbs."

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

"It's not troublesome, it just takes a certain amount of time for the drugs to react with each other." Yuffie said coquettishly.

Mu Liang said mildly: "I will set up a new workshop. When the time comes, you can teach the staff and let them learn how to mix color-changing paints."

The banknote workshop should be opened, the house is ready, and the staff is only needed.

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

"No problem." Yuffie nodded again and again.

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

She looked confused, as if she was about to fall asleep, with dark circles under her eyes.

"I'm going to sleep." Yuffie's pretty face flushed again, and she couldn't hold back her head.

"Okay, I'll go first, and when the workshop recruits all the staff, I'll ask Xiaolan to call you." Mu Liang said warmly.

"All right."

With reluctance in Yuffie's golden eyes, she waved her little hand to send Mu Liang away.

…………

Mu Liang left the 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. 3 paper sent by the paper factory.

No. 3 paper is a special paper for banknotes made from the leaves of the star tea tree.

Section 254

There was a knock on the study door.

Liyue pushed open the door and came in. She had just finished delivering the soil and fertilizer materials to Yue Qinlan.

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

"Make paper money." Mu Liang explained with a smile.

"Need help?" Li Yue asked softly.

She knew what paper money meant, the new currency of exchange that replaced the contribution of value.

"No need for now." Mu Liang shook his head.

He took out the pre-made engraving plate, placed it on the wooden table, brushed the paint evenly on the engraving plate, and then covered it with No. 3 paper, pressing it gently and firmly.

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

Mu Liang changed another piece of engraving plate, and at the same time changed a color, and covered the front and back of the No. 3 paper again.

Li Yue was surprised to see that Mu Liang changed a total of 20 engraving plates, and used the five kinds of paints many times.

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

"Okay." Mu Liang put down the last engraving plate and lifted the number three paper from it.

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

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

There are ten banknotes printed on the No. 3 paper, with a face value of one hundred yuan.

The pattern of rock turtles is printed on the front, and the star tea tree is printed on the back.

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

The pattern of the star tea tree is mainly green and yellow I color, and the other three colors are auxiliary colors.

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

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

"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 shone brightly, carefully observing the patterns and patterns on the banknotes, and she couldn't put it down.

She caressed the banknotes carefully, and found that the pattern on the banknotes had a slight concave and convex feeling.

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

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

The raised pattern on the banknote is specially made by superimposing ten layers of paint on one side.

"So it is." Li Yue nodded slowly.

Mu Liang reminded: "You can look at the banknotes under the light of the lantern beetle."

Li Yue couldn't help being curious and did as she did.

Under the bright light, the 100-yuan banknote changed, and Mu Liang's head appeared under the original rock turtle pattern.

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

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

This is the characteristic of color-changing pigments. The superposition of different pigments, and then through Mu Liang's layer design, finally formed his appearance, which can only be seen under the light.

"Very good design." Liyue exclaimed.

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

Li Yue suppressed her curiosity and continued to look at the hundred-yuan bills.

Originally, there were irregular textures on the paper, which were formed after the leaves of the star tea tree were made into paper.

"Do you want to try printing paper money?" Mu Liang asked softly.

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

"Can I have a 560?" Li Yue was a little eager to try.

"Of course, you can try making fifty-yuan banknotes." Mu Liang took out another set of glazed engraving plates and placed them on the wooden table.

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

"Mu Liang, what color should I use for the first floor?" she asked nervously.

Mu Liang glanced at the carving and said, "Let's use yellow I color."

"Okay." Li Yue responded.

She used a spider silk brush to dip a little yellow I color paint, and brushed it gently on the first engraving plate, carefully brushing every corner.

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

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

Mu Liang said in a clear voice, "Well, just cover the number three paper and press it tightly."

"Okay." Li Yue put down the spider silk brush, picked up a new No. 3 paper, and carefully covered it on the engraving plate.

She pressed it firmly with her hands again, not letting go of every corner.

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

"Okay." Li Yue had a pretty face and a focused expression.

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

Ten minutes later, a set of engraving printing is finished, and ten banknotes can be obtained, which is not very efficient.

Mu Liang frowned, feeling that he should make more sets of engraving plates and recruit more workers to improve efficiency.

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

"Mu Liang, how's it going?" Liyue handed over the printed fifty-yuan banknotes as if offering a treasure.

Muliang checked it carefully, and there was no problem with anti-counterfeiting of patterns and watermarked portraits.

He sincerely praised: "Well, very good."

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

Mu Liang smiled indifferently and asked, "Will you try making a 20-yuan note again?"

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

The two stayed in the study all morning, studying and making banknotes of different denominations.
