On Yangshi's side, there is nothing.

On the other side of the netherworld, news has already come from the previous letter.

On this side of the Yin World in Linjiang County, there are monks who are collecting ghost coins, and there are already ghost coins in their hands that have been traded.

It is said that other people's paper incense candles are sold cheaper than bookstores, and one or two ghost coins can buy a bundle of incense candles.

There is no need to think much about who is collecting ghost coins, it is definitely Qingyutang who has not run away.

The ghost coin Qingyutang can't be used as a silver flower, and it can only be placed there to see, and it can only be moved with the help of true qi.

This is collecting ghost coins at a loss, what else can it be for?

It's just that she hasn't given up on the production method of ghost coins, and she doesn't teach her here, so people want to imitate it themselves.

When she first designed the ghost coin, she was also introduced to paper binding techniques, and it was only a matter of time before Qingyutang succeeded in counterfeiting.

Maybe it's been successfully counterfeited now, but in a short period of time, it's not so easy to make ghost coins in batches.

After all, the texture of the surface of the ghost coin is still quite complicated, and she has a bookstore to print it in large quantities.

But I don't know when, they will think of a way to cooperate with the printing house.

Therefore, the anti-counterfeiting mark of ghost coins is imminent.

Thinking about it, only the special magic weapon that appeared in the jade seal space may be the safest.

She often looked through the Jade Seal Space these days, wanting to see if there were any magic weapons that could solve this problem.

The Jade Seal Space has always been very dedicated to helping her solve her needs, but this time, the Jade Seal Space did not react at all.

Song Yushan had no choice but to give up.

If the Jade Seal Space doesn't have it, then there is only one possibility, she doesn't need a magic weapon, and she has the ability to do this.

If you don't use magic weapons, then you can only find a way to do paper tying.

There are still many restrictions in the yang world, but in the yin world, only by relying on true intentions, supplemented by the general shape of the paper tie, can make everything that may only exist in the imagination.

In the underworld, it can be said that it is an existence that can create all things.

Therefore, there is no doubt that paper binding can make anti-counterfeiting marks, but what she can do, if others know how to make paper binding and imitate it, they will definitely be able to make it.

That's why she hesitated before.

Now there is no other way but to make this anti-counterfeiting mark as difficult to imitate as possible.

Song Yushan thought about Qingyutang's practice of collecting ghost coins, and suddenly had a plan.

If you want to imitate, you must get a sample, even if it is a paper tie, you can't make something that you haven't seen and have no concept at all.

Is there anything that only she has seen, and that other monks who know how to do paper-binding have definitely not seen, and that they can't easily access from other channels in the future?

It was a special item from her memories of her past life.

Song Yushan thought of bank cards, and even thought of mobile phones and online accounts from bank cards.

For a while, I felt that my idea was great, and if it was done, I could fully upgrade the Yin World Bookstore.

Although she does not know much about the structure and principle of electronic devices such as bank cards and mobile phones, it is impossible to restore them through imagination.

But she can rely on the characteristics of the special function given to the paper products by the small adult paper binding technique, and fabricate the corresponding effect by herself!

For example, she can use a blank piece of paper to make a paper tie and give it a similar function as an electronic screen.

It's doable.

But to achieve the effect she wants, she has to add many kinds of effects, layer by layer, to make it possible.

This is undoubtedly a great test of the ability of paper tie-making, and the difficulty is also extremely high.

It's not the same thing as a ghost coin at all.

She only needs to wait for the printing of ghost coins in the bookstore to be completed, and then use paper binding to give the true meaning uniformly, which basically does not consume much time and energy.

If she has a copy of this kind of thing, then she won't have to do anything in the future, just make this netherworld version of the mobile phone every day.

The idea was tempting, but after actually trying, Song Yushan gave up.

But this attempt also gave her a new idea.

She can't produce the netherworld version of the mobile phone, but the netherworld version of the money detector can!

Just equip each bank with a money detector.

Other monks may be able to use incense candle paper to get a sample of the ghost coin to imitate, but few monks know how to make paper at the same time, and the Heavenly Eye Technique has been practiced to the Great Perfection, and dare to go to the money bank in the netherworld to observe the money detector up close.

If there is no opportunity to contact, it will naturally not be imitated.

This is easy, just just prick something random and give it the function of testing some kind of mark in the netherworld.

There is almost no difficulty, and each Netherworld Bookstore only needs to put one in the place where the money is collected, and she can make it at will.

With the money detector in the netherworld, she only needs to add an anti-counterfeiting mark that is invisible to the naked eye and can be verified by the money detector.

Adhering to the purpose of simplifying the complex, Song Yushan pondered whether he could make something and mark the ghost coin.

Or simply make something and put it in the underworld for the final processing of the ghost coins printed in the bookstore.

It doesn't matter if you add to the work for the ghosts, they have a lot of time to do nothing.

Any paper bundle she makes can't replace her with true meaning.

But the ghost coin itself is paper money, in the yin world and in the yang world, there is no material difference, not like a paper house, paper clothes, there are changes in the material, in fact, it is not necessary to have true intentions.

It's just not as beautiful as the ghost coin that she personally gave the true meaning to.

What's the use of looking good? The most important thing is that the cost is low compared to the degree of exquisiteness, and the difficulty of making but the difficulty of imitation is the most important.

Song Yushan immediately pricked out two test pieces.

One is a counter paper tie with a currency detection function, and the other is a rectangular stamp that can automatically produce colored ink and engrave a coin pattern.

She sent a letter to the blind scholar, and burned the counter paper to the Yin Shi Bookstore in the county town overnight, replacing the cash register counter in the original bookstore hall.

Then he casually cut a rectangular piece of yellow paper and burned it to the blind scholar waiting in front of the counter.

Finally, the seal was burned.

Later, Song Yushan himself also went from the entrance of the netherworld in the valley to the netherworld bookstore in the county town.

When she arrived, the blind scholar took the seal and pressed it lightly on the yellow paper.

Colorful patterns and words appeared on the yellow paper.

This is the new version of the one- or two-dollar ghost coin.

At the same time, these patterns and characters emit dazzling colors on the counter with the function of checking money.

Pick up the ghost coin from the counter, and the colored light disappears, leaving only the colored lines.

In this way, the monks of the Yang World could not imitate the real ghost coin in front of a piece of yellow paper that was only the most ordinary existence.

It's just that this new version of the ghost coin still feels like a yellow paper, which is more than a step worse than the high-end texture given by the sincerity of the previous ghost coin.

But the colored lines are very much in line with the aesthetics of ghosts.
