Of course, Shi Yiwen is not clear about what others think. Besides, as soon as he returned to the capital, he was busy.

First of all, we have to go to the library to print the book, although the book "Pressurized Water Well Method" has already been written, but it is still necessary to add some patterns.

After a busy day's work, after drawing out the drawings that need to be added, Shi Yiwen came to the book building and watched the workers shake the lithograph to print the pages, with the rotation of the printing machine, one by one the pages were printed, and the ink on the slightly yellowed paper was very clear.

There is a faint fragrance of ink in the printing workshop, the reason why lithographs are very popular in modern China is not only because he is similar to traditional printing, easy to make plates, but also because as a kind of lithographic printing, it can directly use cheap domestic ink, and the life of corroded slate is extremely long, and it can be printed tens of thousands or even hundreds of thousands of times.

Such advantages have made the lithograph machine popular in China, and as for the replacement of lithographs by lead printing, it will also wait until after liberation, with the development of metallurgical and chemical industries.

"This seal is so clear......"

Looking at the printed book, Shi Yiwen couldn't help but sigh.

"Childe, if our ink is mixed with two percent of water, this handwriting will not be as light as it is now, and the cost can be reduced."

As the shopkeeper of the "Qizhi Library", Sun Fengshan once again put forward his suggestions on the cost.

"Shopkeeper Sun, business is not like this, even if you add two percent more water, how much can you save? Just 15,000 copies of the Pressurized Water Well Method, how much can be saved? Is it a hundred taels? Or how much? ”

Shaking his head, Shi Yiwen looked at Sun Fengshan and said.

"If you want to reduce costs, you can find a way to produce paper and ink, and you don't have to cut corners.

Diverting the topic, Shi Yiwen asked another thing.

"Boss, I was looking for you, please move upstairs."

In the upstairs cubicle, Sun Fengshan took out a yellowed piece of paper and said.

"Boss, look, this is the mulberry paper that our paper mill has tried to produce under your orders."

Taking the pale yellow paper, Shi Yiwen deliberately felt its feel, the paper was tough and shiny, and the sound was crisp. It doesn't seem to be much different from the banknote paper of later generations, just thicker.

"Owner, this paper took two months before and after to make, its practical knot incense to make paper, is not rare, more common in the south, knot incense leather paper is very good ink resistance, with its writing ink does not seep or soak, it is more delicate and soft than ordinary mulberry paper, the paper is more delicate and even, flat and smooth. However, now that cotton and linen have been added, it is much tougher and stiffer......"

Looking at the owner, Sun Fengshan tried to say.

"It's just that I really don't know, why does the owner make this paper at the expense of work?"

Facing Sun Fengshan's incomprehension, Shi Yiwen smiled.

"Print a silver ticket!"

Smiling slightly, Shi Yiwen picked it up again, looked at the light, and could see the watermark between the papers, watermark technology is not a new technology, and now many paper mills will add watermarks to the corners of the paper to indicate the "brand".

Sure enough, as mentioned in the information - the biggest feature of the three-tree paper is that the watermark is very clear. The so-called "three-bark paper", which is unique to Japan, is actually Chinese leather paper, and the incense called "three-bark wood" in Japan is just one of the raw materials of mulberry paper, which should be the best "banknote paper" that can be found in this era.

"With it, we can print counterfeit silver tickets."

Contains cotton flax paper, ink、...... These are all means of ensuring the counterfeiting of silver tickets, of course, it would be better if there were gravure or even anti-counterfeiting color-changing inks.

Of course, all this is now in preparation for the future, after all, the use of silver tickets is not widespread now, mainly for one person, only occasionally for some people. But you always have to prepare for everything.

Thinking of the silver ticket, Shi Yiwen naturally thought of his partner, who hadn't seen him for a while, and didn't know what he was busy with.

But after thinking about it, Shi Yiwen could also guess that he would definitely not be more comfortable than himself, after all, there was such a "strong minister" resting there. Thinking of that "strong appearance", Shi Yiwen's brows frowned slightly.

Zhang Juzheng!

Now that he is really in his eyes, it seems that contact with him in the future is inevitable, but under what circumstances will he see himself?

I am also a book and a mold.

It stands to reason that at this time, Zhang Juzheng should summon himself.

Could it be that he is waiting for him to take the initiative to meet him?

Wouldn't it be too reckless to come to see him like this?

Do you need to ask Ma Ziqiang first, in contrast, these pavilion elders seem to owe Ma Ziqiang a favor to him. As for Lu Tiaoyang...... People are in Guangxi.

Just when Shi Yiwen was thinking in his heart if he didn't want to see Zhang Juzheng, Zhang Juzheng's sedan chair over there returned to the gate of Zhang's mansion in Wusha Hutong, and it would be dark. The four lanterns hanging under the eaves of the gate glow softly. As soon as Zhang Juzheng got off the sedan chair, the servant hurriedly stepped forward to report.

"Master, Qi Dashuai has arrived."

"Oh, where is he? Why didn't anyone notify me? ”

"It was the lower officials who told them not to disturb Shoufu who was busy with business."

At the same time as the words sounded, Qi Jiguang had already strode out of the gatehouse, waving his hands to salute, as usual, Qi Jiguang, who was the chief soldier of Jizhen, came to Zhang's mansion to meet Zhang Juzheng as soon as he returned to the capital. Although Shoufu was not in the house, he was still waiting at the gatehouse, and deliberately told his subordinates not to disturb Zhang Juzheng. While explaining, Qi Jiguang waved his hands at first sight.

"See Shousuke for the lower officials."

Seeing Qi Jiguang, Zhang Juzheng knew that he must not have eaten yet, and the porter would not prepare meals for visitors, so he smiled and ordered his subordinates to prepare rice and tea, and then said to Qi Jiguang.

"Yuan Jing, how long have you been here?"

"It's just an hour."

Qi Jiguang said respectfully.

"When Xia Guan looked for a few days ago, he hunted a tiger, this thing is the best for the body, Xia Guan thought about the first assistant to work all day long on state affairs, it is inevitable that he will hurt his body. He brought it to the first assistant to replenish the body. ”

Every two or three months, Qi Jiguang will find an excuse to go to Beijing to meet Zhang Juzheng, the relationship between the two can be said to be very close, and every time Qi Jiguang comes, he will bring some game and specialties, Zhang Juzheng has long been accustomed to this, so naturally he did not refuse.

"That is, you, you are talking about me all day long, this time you come to Beijing, just stay here for a few days."

Zhang Juzheng said with a smile, and then walked to the study with Qi Jiguang.
