Li Si didn't get any useful news here, so the monkey paid attention, and he didn't find anything, after all, finding a person in the capital so many times is tantamount to looking for a needle in a haystack, and later Zhang San reminded him to start with the families of these people, and gradually found out some clues.

There are more people poaching corners in papermaking and printing, and Zhang San thinks the same, all people who have a certain sales volume of newspapers have some ideas about Zhang San's business, but most people feel that they try it secretly, but there are also unscrupulous, such as Rulin Daily, Bianliang Daily, Bachelor's Daily, Calligraphy and Painting Newspaper, etc., which are obviously with official backgrounds.

For example, there seems to be Gao Yu standing behind the Rulin Daily, Zeng Gong supports the Bianliang Daily, the Bachelor's Daily is made by a group of people from Taixue, and the Calligraphy and Painting Newspaper is supported by Cai Jing and others.

The easiest thing is to kill them directly, but some people are still useful, and some people are still doing a good job of security, but Zhang San is easy to attract attention for breaking the rules of the game.

But fortunately, for the time being, they don't dare to be too blatant, Zhang San doesn't value their earning ability for these two businesses, and besides, even with the same technology, Zhang San still feels that he can easily defeat them.

As for stealing the wine-making technology, it is those peers who are in the same door, and the famous restaurants in the capital all know that Zhang San has a kind of spirit, but they only think that this is just a kind of wine, so some people poach but no one does their best.

At this time, they didn't know that this wine could be used to make perfume and disinfect wounds, otherwise there would be more people who coveted it, and Zhang San felt that in addition to strengthening his secrecy work and doing a good job in screening these personnel, it was time to set up an assassination and sabotage organization.

For this kind of people who eat inside and outside, Zhang San thinks it's time to teach them some lessons, otherwise they still think that Zhang San is a good bully, Zhang San may not be able to stop others from poaching, but if you dare to dig my people, I will dare to kill, set your workshop on fire, or add something to your products.

In addition to these things this time, Zhang San also asked Li Si to select a few experienced paper-making craftsmen, and Zhang San wanted to make a special kind of paper, that is, silver ticket paper, which was intended to be produced in the Ryukyus.

Since Zhang San established the bank, Zhang San has always wanted to issue silver bills, but the development speed of Yixing Hutchison has not been very fast, and Zhang San's funds are limited and cannot meet the exchange requirements, so it has been delayed again and again.

But now with the funds of the Zhang family, the development of Yixing Hutchison has spread rapidly, although it cannot be said that every city has it, but it has also achieved that several capitals passing through the dart road have a Yixing Hutchison, or plan to build a Yixing Hutchison.

So Zhang San felt that it was time to launch his own silver ticket, the most important thing in the silver ticket is anti-counterfeiting, the first step of anti-counterfeiting is special paper, Zhang San naturally has a lot of banknote paper in his mind, and finally Zhang San still chose the paper of the Taiwan dollar as the blueprint, because there is a plant in it that is a specialty of the Ryukyus.

This is a vine plant, which is generally mixed together to grow, like a twist flower, so Zhang San named it Twist Vine, which sounds kind and a very valuable feeling.

After adding this vine, the silver ticket paper is difficult to be imitated, in addition to the paper, the color printing process is also an anti-counterfeiting means, the complex group has special colors and ink printing can not be easily imitated.

After that, there are two trump cards, one is watermark technology and one is color-changing ink technology, the watermark is very simple, Zhang San uses the layered pulping method, the first step is to pour a layer of pulp in the sand frame, and then glue a layer of special fibers with the watermark plate to print on the semi-dry pulp, and after the pulp is fixed, a layer of pulp is gently poured on it.

As long as the technology is in place, the thickness of the paper will not increase much, but the watermark is made, of course, this is just the simplest watermark, I am afraid that the clarity of later generations cannot be compared, but it is difficult to imitate, and it is not three or two people can complete the imitation.

As for the color-changing ink marking, this is definitely a unique technology, with these three anti-counterfeiting methods in addition to a series of special algorithm composed of numbers, it is enough to issue silver tickets, and Zhang San has high hopes for this kind of silver tickets.

Silver tickets are divided into two kinds, one is an anonymous small amount of silver tickets, that is, consistent, two, five, ten four denominations of silver tickets, to put it bluntly, is to replace the function of a part of the pen and paper, originally Zhang San also planned to issue a small denomination of 100 and 200 silver.

But Zhang San doesn't have that kind of credibility now, and he doesn't want to take too big a step, and he will face troubled times soon, and the country will have no credibility at all, not to mention that Zhang San is just a businessman.

The production process of this kind of banknote is complex, the production cost is higher, and only the large denomination of more than ten yuan can be made to make money, and the large-scale popularization can not replace the status of copper coins.

There is also the frequent occurrence of wars, there are often state capitals that are breached, and the more types of face value there are, the more money that needs to be reserved in order to prevent runs, and Zhang San can't afford to spread such a big stall.

There are also more than 100 registered silver tickets, which use the method of secret deposit and password, and this kind of silver ticket is generally directional, that is, the person who saves the money will specify the place of use, such as taking it in Hangzhou, or it is limited to Tokyo.

This is equivalent to a large amount of transfers, after all, the secret deposit and password must be known by fewer people, the better, if someone saves money, he will send his verification method to the whole country, which is not only a waste of human resources but also increases the risk of leakage.

For this era, Zhang San's way is advanced enough, especially bearer silver tickets, at the beginning Zhang San will be issued in a one-to-one ratio, and then can be exchanged at any time, as long as the credibility is there, then many people will carry silver tickets to other places to withdraw money, or even directly use silver tickets to trade.

Zhang San planned to first introduce three small banknotes of 10 Wen, 20 Wen, and 100 Wen in the Ryukyus to be used with copper coins, and then Zhang San's influence would expand wherever this kind of paper money would be promoted, and other places would use this large amount to see what would happen later.

Zhang San also has no outstanding economic talent, I don't know what kind of reserve ratio is the most scientific, and Zhang San must be ready to turn his face with the imperial court at any time, so Zhang San intends to use a one-to-one reserve ratio, it is okay not to make money, but it cannot be without credibility. Otherwise, it will be difficult to pick it up.
