The villain powerful minister pitted his tech house

Chapter 535

But... this major is not suitable for her, and she is not very good at it.

Song Shushu looked at the old and frail Master Shangshu, who was already full of the vicissitudes of the years, and now he was deeply worried and wrinkled, and nodded reluctantly.

"Okay, I'll try."

##
It is not difficult to make anti-counterfeiting marks, but it is very difficult to make anti-counterfeiting marks that other people can't make at all.

Song Shushu wanted to learn from the technology of anti-counterfeit banknotes in the earth age in the past, and try to make anti-counterfeiting technology.She checked for a long time and found that even the anti-counterfeiting technology of the early earth age is difficult to achieve.

All of them are technological monopolies, and it is quite difficult to replicate them.

Song Shushu searched for a long time before he found a simple watermark and security thread.

Normally, coin watermarking should be done during papermaking, before the pulp is completely solidified, and the density of pulp fibers is changed through a prefabricated copper mesh.This method is very difficult, so I used the counterfeit method, two sheets of paper mixed with a watermarked paper, so that the same effect can be achieved.

The disadvantage of this method is that the banknotes made will be layered, soaked in water and rubbed, and the banknotes will be scrapped.

But it's better than nothing.

Watermark paper has to be made by yourself.

Song Shushu looked at the materials every day, and then sighed deeply, what was all this about.

"Books."

Fu Xuan, who had been honest for more than ten days, made a comeback, holding Song Shushu in his arms, and fumbled dishonestly with his hands.

Song Shushu put down the things in his hands, then looked at Fu Xuan, "Can you make watermark paper?"

Fu Xuan was taken aback, "What paper?"

Song Shushu sighed, and waved his hand at him, "I don't know this at all, this is the consequence of being full of yellow waste in my mind."

Fu Xuan looked at the things in Song Shushu's hands, and quickly understood what she was talking about, "But Liu Kaitai begged you to make an anti-counterfeit mark? He should be responsible for this thing. He is really good at sneaking away. Forget that this bank is Whose is it?"

Song Shushu glanced at Fu Xuan's expression of dissatisfaction and making excuses, "Be sober, the bank is yours, and he is working for you."

Fu Xuanmo paused for a moment, then looked at Song Shushu, "What is this watermark paper used for?"

"This one." Song Shushu stacked the three sheets of paper in order, and through the light, one could clearly see that a pattern was printed on the white paper.

Fu Xuan reached out to take the three blank papers, looked at them separately and then closed them again, "Shushu, how did you do this?"

"That's how it was done." Song Shushu said casually, "I found out that there is a special kind of paper in Fucheng, which can make a watermark effect."

"Then you are still troubled by this?" Fu Xuan asked.

"Because this kind of paper is folk, if someone finds out this secret, they can make paper with the same effect, and it can't play the role of anti-counterfeiting." Song Shushu shrugged casually and said, "So a new technology is needed to achieve Technology monopoly. It would be even more perfect if the watermark could be created directly using the copper mesh.”

"Is it difficult?" Fu Xuan asked.

Song Shushu nodded, "The major is wrong, everything is very difficult."

Fu Xuan looked at the scattered papers on the table, and hugged Song Shushu distressedly, "Thank you for your hard work."

"Since you think I'm working hard, can you take your hands off my ass?" Song Shushu looked at Fu Xuan with salty eyes, "Speak well, why are you rubbing my ass?!"
