The Eagle Rig that had been saved for two months was sold out in one afternoon, but most of it was on credit. A set of the most ordinary sets of golf equipment also costs more than 20 runs, and who will run around the street with 20 strings of copper coins. Fortunately, the personal credit in this era is still reliable, as long as you sign it, let alone twenty times, and you are not afraid to add a zero later.

"When I have money and other officials, I will get a bank and issue credit cards and mortgages. Don't look at how happy they are now, they will all have to be honest as Kanu and house slaves when the time comes! ”

When he went home at night and saw the string of signatures on the account book, Hong Tao had the urge to immediately bring someone to the door to ask for the account. Remembering a bunch of pit things in his mind, he threw away the account book, and reached out to hold the princess in his arms. Aren't the ancients cloudy, full of warm thoughts**. I just made a small amount of money, so it's warm.

Similar to Hong Tao's estimate, the buying boom of flying eagle equipment only lasted for three or four days, and then it stabilized, and two or three sets could be sold every day, and the largest sales volume was still balls. This thing looks inconspicuous, but the production technology is more difficult than that of a badminton racket, and the stability of the copycat imitation is not enough in a short period of time.

Obviously, it is unlikely, at least not yet, to make a lot of money selling sporting goods. The most popular places for badminton are the backyards of the imperial palace and the official palace, and I don't know how the Song people figured it out, they were more keen on expanding the court and then playing three-on-three matches. This makes it more lively and more ornamental.

The Song people did not plan to pay too much attention to the improvement of badminton, and after more than half a month of hard work, the six royal gold and silver masters finally gathered more than 600 copper molds of commonly used words. The test of casting lead characters was done when the first batch of copper molds were manufactured, and the effect was ...... Neither good nor bad.

This means that the hardness of the lead alloy is not suitable, and the cast lead characters are still slightly adhered to in very small parts. But after the later restoration of the craftsmen's skillful hands, most of them can still be used.

Therefore, Hong Tao does not plan to improve the proportion of lead alloy for the time being, so he will use these lead characters for printing first. After completing the first orders for Hoedo, the craftsmen will slowly explore it.

Not only the proportion of lead alloys, but also the improvement of the printing press. They are only responsible for guiding the way, and at most they will take it forward for a while, and they will have to complete the road on their own.

"Officials are really miraculous skills, they, they ......" When page after page of the imperial court newspaper was taken down from the printing plate and hung in the Feiyu Hall to dry, the first person who couldn't help it was Xu Donglai.

He attended a literacy class in the Salesian Bureau, but he did not participate in the scientific examination, not because he didn't want to, but he couldn't, and he didn't have so much money to buy books to read. And his background is destined to be unable to find a scholar friend to borrow, and he can't even get a manuscript.

The scientific examinations of the ancients are similar to those of modern times, requiring a lot of reading and exercises, without textbooks and exercise sets, and wanting to do well in the exam is tantamount to a dream.

These two not very clever presses gave him hope, according to the horse, no matter what they printed, this machine had only two advantages, one of which was low cost, and the more you printed, the lower the cost.

Regardless of the wear and tear of that character, the plate should not be scrapped, just cut out the lead and replace it with a new one. Without the cost of printing plates, ink, labor and paper alone are really not worth a few dollars.

The second is fast and flexible, because the printing plate is composed of hundreds of lead characters, theoretically speaking, a book of hundreds of pages can be printed by hundreds of printing plates at the same time, all that is needed is enough lead words and enough printing presses, and the printing content can be adjusted at any time.

In this way, whether you print 10,000 copies or 100 copies, it can become a reality, or for that reason, there is no need to be stereotyped separately.

And what is the structure of the printing press invented by Hong Tao? If the printing craftsmen of the Jinhe Empire were to see that the printing press made by the emperor was such an unlucky virtue, they would definitely wonder if the emperor was a fake.

It is called a printing press, but it is actually a long wooden table with a track, one end is used to hold the printing plate, and the other end is a simple press.

Each printing press is operated by two people, one of whom holds two huge puffs in his hand and dips them in the appropriate amount of ink to apply to the printing plate; The other person puts the paddled white paper on the printing plate, pushes the backing plate under the printing plate, sends the printing plate to the press, moves the handle, and uses the lever principle to apply pressure to the printing plate, so that the paper is fully in contact with the printing plate.

And then...... And it's done. Remove the paper and clamp it to the rope like drying clothes, and dry the ink, and then you can print on the reverse side.

It is not objective to say that there is no technology at all, the amount of ink applied and the amount of pressure need to be found by the craftsmen themselves, and the temperature change also has an impact on the fluidity of the ink.

But these questions are not critical, let alone a craftsman with a clever mind, even after Hong Tao himself tried it a few times, he also had a lot of experience. This thing is not difficult, three words, familiar with it.

As for the cost of the printing press, Hong Tao was embarrassed to brag. A few broken wooden boards, a few ropes for fixing. Not to mention the lever pressure device, Peng Da said, this thing is not as complicated as the device for pressing dried tofu in his hometown. And repeatedly hinted that don't use his name to name the printing press, it's too embarrassing, and the reputation of this life will be ruined.

"Don't make noise, don't shed tears when the big man is fine. I've got a mantra here for you to take and recite with the children. When the printing press is free, print some and give one to each child. I will slowly help you make up for the books you haven't read, not only can you serve the country through the imperial examination, follow me well, sooner or later your name will be written in the history books. Don't worry, I always count. ”

Xu Donglai was thinking in his heart, what Hong Tao could guess, compared with later generations, the ancients had a greater thirst for knowledge. It's not that they're studious, it's that they have too few opportunities to access knowledge, and they love what they lack, which is the truth.

But it's not enough to just provide them with knowledge, Hong Tao also has to play some political commissar tricks to buy people's hearts! Xu Donglai is different from Gao Cuifeng, Wasp, and Zhu Bajin, relatively speaking, he is relatively pure and needs to invest more emotionally.

"The grace of the big officials dare not forget...... is so foolish, a broken book knelt down.

If Xu Donglai knew the content of the history books that the horse said, it is estimated that he would be able to turn his face immediately. The history books are really not even, but it is very likely that it is not a positive character, but a big traitor, and it is not a luxury to leave a stench for 10,000 years.

"If an official wants to publish a book and say that it is a big deal, it is better to set up a banquet in the palace and invite guests to make a preface and inscription for this book, if the official family is willing to come, it is not impossible to ......."

Seeing that Xu Donglai was about to go to the history books, Gao Cuifeng felt a little uncomfortable. In terms of learning, he didn't dare to say that he was taller than a horse, and that was also incomparable to other people in the house. It should be his turn first, it seems that the work of assistance is still not at home, and the critical moment can't let the colt think of himself, so hurry up and work hard.

"This book is for Mengtong to learn, and there is no need to bother the officials. But your idea is very good, don't worry, I have a lot of goods in my stomach, and when I have time to write it, there will be several copies. When the time comes, please help me proofread the words and sentences, which can be regarded as co-authored by you and me, and after they are printed, they will be specially studied by those professors and doctors in arithmetic and Taixue. ”

It's a good thing for his subordinates to compete for performance, and even if they don't plan to cultivate, they have to be kind and give some hope. This time it's not timeless, it's changed to educate the world, and the pie is not small.

"The students didn't dare to ...... Since he thought that Mr. wanted to ......, "yes, I don't know what the content of the book is, Gao Cuifeng thinks of himself as a student, and Mr. calls it a smooth mouth."

You must know that in this era, the title of the master is not as powerful as that of the gentleman. Didn't the ancients say that being a teacher for one day and a father for life is almost equivalent to recognizing a godfather.

"It's not enough to just think about it, in the future, Bao Huitang will be presided over by Xia Shu, can you?" When the sweet dates are given, the burden has to be carried.

"Students will live up to the trust of Mr. ......" Although Gao Cuifeng did not kneel, this bow is similar to the meaning of kneeling, and it is obviously more likely and realistic to write a book and speak than in a history book.
