I am doing meritorious deeds in Liaozhai

There is nothing wrong with Yang Shi.

On the other side of the underworld, news has been sent in the previous letter.

On the Yinshi side of Linjiang County, there are monks collecting ghost coins, and ghosts have already traded the ghost coins in their hands.

It is said that other people's paper-wrapped incense candles are sold cheaper than in bookstores. One or two ghost coins can buy a bundle of incense candles.

There is no need to think too much about who is collecting the ghost coins. It is definitely Qing Yutang who has not escaped.

Qingyutang's ghost coins can't be used as silver coins after they are collected. They can only be left there to look at. They can only move with the help of infuriating energy.

This is collecting ghost coins at a loss, what else is it for?
But she hasn’t given up on how to make ghost coins yet. If she doesn’t teach them, people will just find ways to imitate them themselves.

When she first designed the ghost coins, she was just getting started with the paper-tying technique. It was probably only a matter of time before Qing Yutang succeeded in counterfeiting them.

Maybe it has been successfully counterfeited now, but it is not that easy to mass-produce ghost coins in a short period of time.

After all, the surface texture of ghost coins is quite complicated, and she only has a bookshop to print in large quantities.

But there was no telling when they would come up with the idea of ​​cooperating with the book printing house.

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

After much deliberation, only the special magic weapons that appear in the Jade Seal Space may be the safest.

She often looks through the Jade Seal Space these days to see if there is any magic weapon that can solve this problem.

Jade Seal Space has always been dedicated to helping her solve her needs, but this time, Jade Seal Space didn't respond at all.

Song Yushan had no choice but to give up.

If there is no Jade Seal Space, then there is only one possibility. She does not need a magic weapon, she has the ability to do this on her own.

If you don't use a magic weapon, you can only find a way through the paper binding technique.

There are still many restrictions in the upper world, but in the underworld, you can make anything that may only exist in your imagination by relying only on your true intentions and the rough paper shape.

In the underworld, paper-tying can be said to be an existence that can create all things.

Therefore, the paper-tying technique can definitely make anti-counterfeiting marks, but what she can do, if others know the paper-tying technique and are willing to imitate it, they can also do it.

That's why she hesitated before.

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

Song Yushan thought about Qing Yutang's method of collecting ghost coins, and suddenly came up with a plan.

If you want to imitate, you must get a sample. Even with the paper-tying technique, you can't make something you haven't seen before and have no concept of.

Is there something that only she has seen, and that other monks who know how to paper tie have never seen, and cannot easily come into contact with from other channels in the future?
That was naturally a special item from her past life memory.

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

For a moment, I felt that my idea was great. If it came true, I could fully upgrade the Yinshi Bookstore.

Although she didn't know much about the structure and principles of electronic devices such as bank cards and mobile phones, it was impossible to restore them through imagination.

But she can rely on the characteristics of the beginner-level paper-making skills to give special functions to the paper-making products, and fabricate the corresponding effects by herself!
For example, she can use a piece of white paper to make a paper tie and give it a similar function to an electronic screen.

It works.

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

This is undoubtedly a test of the paper-tying skills, and the difficulty is also extremely high.

It's completely different from ghost coins.She only needs to wait for the printing of the ghost coins to be completed in the bookstore, and then use the paper binding technique to unify and give the true meaning, which basically does not consume much time and energy.

If something like this had to be done by someone else, then she wouldn't have to do anything else, just make this hellish version of the mobile phone every day.

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

But this attempt also gave her new ideas.

She can't give birth to the underworld version of the mobile phone, but the underworld version of the banknote detector can!

Just equip each bank with a currency detector.

Other monks may be able to use incense candles and paper to get samples of ghost coins to imitate, but few monks know how to paper-tie. At the same time, they have also practiced the celestial eye to the Great Perfection, and dare to go to the bank in the underworld to observe and experience it up close. Money machine.

If there is no chance of contact, naturally it cannot be imitated.

This is easy, you just need to stick something randomly and give it the function of testing a certain mark in the underworld.

There is almost no difficulty. Each Yinshi Bookstore only needs to put one in the place where the money is collected, and she can make it easily.

With the banknote detector sitting in the underworld, she only needs to add an anti-counterfeit mark to the ghost coins that is invisible to the naked eye and can only be verified by the banknote detector.

Adhering to the purpose of simplifying complexity, Song Yushan also wondered whether he could make something specifically to imprint ghost coins.

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

It doesn't matter if you add more work to the ghosts, they have plenty of time to do nothing anyway.

Any paper tie she makes cannot replace her true meaning.

But the ghost coins themselves are paper money. There is no material difference between the Yin world and the Yang world. They are not like paper houses or paper clothes. There are changes in material. In fact, it does not necessarily require the true meaning.

This is just not as beautiful as the ghost coin that she personally gave the true meaning to.

What's the use of looking good?Compared with the degree of exquisiteness, the most important thing is low cost, easy to make but difficult to copy.

Song Yushan immediately took out two test specimens.

One is a counter paper stamp with currency verification function, and the other is a rectangular seal that can automatically produce colored ink and is engraved with coin patterns.

She sent a letter to the blind scholar and burned the counter paper overnight at the Yinshi Bookstore in the county town, replacing the original cashier counter in the bookstore lobby.

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

Finally, the seal was burned.

Then Song Yushan himself went from the Yinshi entrance of the valley to the Yinshi 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 one or two face value ghost coins.

At the same time, these patterns and words emit dazzling lights on the counter with the currency verification function.

When you pick up this ghost coin from the counter, the colored light disappears, leaving only the colored lines.

In this way, the monks in the Yang world would be unable to imitate a real ghost coin from a piece of yellow paper that is just the most ordinary thing in itself.

It's just that this new version of ghost coins still feels like yellow paper, which is far worse than the high-end texture given by the true meaning of the previous ghost coins.

But the colorful textures fit the ghost’s aesthetic perfectly.
