After all, mimeographing technology is not very easy to use even in later generations, let alone in ancient times three hundred years ago. It only took two days for the Academy of Sciences to come up with a new printing press designed by Jiang Tian, but after actually using it, everyone shook their heads.

If other onlookers didn't dare to question Jiang Tian, Zhang Huan, who was joining in the fun, didn't have this scruples: "Sir, listening to your explanation, the students have already understood the truth, but looking at the things printed, they can't make a book!" ”

Jiang Tian picked up a finished product and looked at it, not to mention that he ignored a problem, that is, there was no wax paper that could be used to make plates in this era, and the alternative method of the Academy of Sciences was to smear oil on mulberry paper, then use a knife to carve out the text, and finally print it one by one. But in this way, not only the cost is greatly increased, but the ink effect on rice paper is not very good.

"The theory is possible, it's just that the material limits the play, but I don't expect this thing to replace movable type printing." Jiang Tian, the initiator, had no choice but to conclude that the newly born mimeograph printing press was: "Before the breakthrough in papermaking technology, the printing press is useless." ”

Everyone thought to themselves that you are not joking us, in fact, it is not that there is no special paper for ink, and many of the Bibles brought by those missionaries were made by European movable type printing presses, but our country lacks copper, otherwise there is no need to study any lead movable type.

Jiang Tian looked at them one by one as if he was a little depressed, but he didn't dare to laugh at himself openly, and his lost expression looked very funny: "Don't be discouraged, at least I have already explained to you the truth that oil and water are incompatible, so you can use this principle to invent a printing technology, who of you can use the knowledge you have learned to imagine the general outline of this printing technology?" ”

The people in the courtyard who watched the excitement were not only the students of the Imperial Academy, but also many researchers from the Academy of Sciences, and when they heard him say this, they knew that this prince Shaobao really had a hidden hand, but the reason was very simple, and it was a little difficult for them to imagine using such a simple principle to invent something. Seeing that the sun was rising, Jiang Tian was not in a hurry to reveal the answer, but took the printing press to explain some common physics knowledge, which was counted as today's lesson. It wasn't until someone reported that someone from the Jiang Mansion had sent lunch.

When it was time for the end of class, Jiang Tian came to the spirit: "Don't be in a hurry to leave, but someone has come up with what the new printing technique looks like?" ”

Jiang Tian's words aroused everyone's curiosity again, but curiosity is curiosity, and he just can't think of how to solve this problem. At this time, Jiang Tian didn't sell it anymore, and took the food box handed by Xi Yun, but took out two stones from inside, these two stones looked blue-gray, cut into the size of a book, and the surface was smooth and flat. Then Jiang Tian found a brush dipped in the remaining ink of the failed work, wrote a "medium" character on the slate, and when the ink dried slightly, he poured a bowl of water on the slate, and the water stains quickly seeped into the stone, and after repeating it several times, until the surface of the stone was slightly damp, but not so wet that the paper, he picked up the pen and continued to depict it along the original handwriting, and then picked up a piece of paper and pressed it on it, and took it off and printed an upside-down "in" character. The only thing to pay attention to is to keep the stone moist, otherwise it is easy to destroy the original handwriting when copying again.

In the whole courtyard, even the students and researchers were dumbfounded by this unbelievable printing method, no wonder people reminded them at the beginning of how to use the incompatible characteristics of oil and water. But why can't I think of such an ingenious method? What's even more incomprehensible is that the effect of this method is higher than that of the mimeograph machine, and the cost is even lower than the price of a stone, but people are unwilling to sue the Academy of Sciences, and they have to let everyone turn a corner to know.

Jiang Tian threw down his pen and pointed to another intact stone slab and said to the false prince, "Sicheng, you come here to draw a dead tree." ”

Wu Yuan was still immersed in shock, but after hearing the task assigned by Jiang Tian, he woke up like a dream, and sighed with a high-five: "Wonderful, Mr. is really a god!" ”

Many people have seen that the biggest highlight of lithographic technology is that it has broken through the limitations of traditional movable type printing, and can be typeset and written at will, without the size of the movable type itself, of course, the font must be reversed. What's more, it can be painted and rubbed out at will, which saves the complex process of traditional engraving printing. Wu Yuan is also not polite, although ink painting is not as casual as ink, but his foundation is solid, and it is not difficult to draw a withered pine, and then he does not need Jiang Tian's instructions, he will operate according to the process he just saw, until a printed "Dry Pine Map" is presented in front of people's eyes. If there were still people who doubted Jiang Tian's ability, but now when people saw with their own eyes that he could casually come up with two novel printing methods, especially the impressive simplicity of lithographic technology, if anyone dared to question his ability, these people in the courtyard would be the first to refuse.

Song Yi, who was still excited, completely forgot about the elders and children, and pulled Jiang Tian and asked eagerly: "What Mr. thinks, the students are less than one, but how did you come up with such a print?" ”

Jiang Tian smiled, he didn't dare to say that this unique skill was plagiarized from the university art club: "In the past two days, there have always been stonemasons who come here to repair, and the thing they use to build joints is the lime, and the lime is this blue-gray stone before it is fired into white, because of its loose texture, it can absorb water, and then think of the relationship between oil and water, this method is naturally derived." It's all because I know more physics than you do, so I can come up with a whim. ”

No one dared to refute Jiang Tian's boasting, the facts in front of him were here, the stonemason was knocking around him every day, who noticed the materials used by the other party? I had heard the truth that oil and water are incompatible two days ago, but who would have thought of such an exquisite design? No wonder the saint didn't say a word and gave himself a prince and a young guard, it turned out that his own junior brother knew better, I am afraid that if it was not difficult to convince the public, some people would have a bad heart, and no matter how high the official position was, it would be given together. Tian Xuhai, who was standing in the crowd, could only sigh in his heart, if such a simple and easy method was popularized, all the readers in the world would have the ability to publish their own works. It is said that this is the gospel of Confucianism, but he thought of another problem, the reason why the original scholars are superior is nothing more than to occupy the righteousness of the scientific examination, the convenience of books, if anyone can print books by themselves, then the Confucian classics will inevitably be drowned in the various whims of the mountain villagers, coupled with the uncertain factors of the scientific examination, if Confucianism wants to use the great righteousness and the small words, the public mouth to determine the good and the evil and the inferior...... But it's not that easy!

Naturally, the new printing technology was reported to the Son of Heaven by the Academy of Sciences, and Jiang Tian, who had completed a day's work, ignored the students who were immersed in novelties, but let them toss casually. Anyway, there are only a few stone slabs prepared, and they will stop when they are broken, and the price of limestone is very low, but it needs to be carefully polished by stonemasons before they can be used, so there is no need to worry about them being too addicted. When Jiang Tian was in school, his enlightenment teacher once said: Students who can't play are mediocre, students who can only play are stupid, and people who can find fun in learning and learn knowledge in games are geniuses who can be met but not sought. So his old man's education principle is: when it's time to play, be happy, when it's time to learn, take it seriously, no one expects you to be a genius, but at least you can't be stupid and mediocre. Later, I heard that this engineer of the human soul was suppressed by his peers and parents, and he had to leave his teaching position in disgrace. After recalling the mentor in his heart, Jiang Tian once again retreated to his home for no reason. However, he didn't have time to enjoy the relaxation of getting off work, because after a few days of ideological struggle, someone had officially proposed to leave Jiang's Mansion and start a new life.

"Now that you've all thought about it, I won't say anything more, and according to the previous promise, I will give you a settling-in fee." Jiang Tian didn't mean to keep much, he always felt that there were too many people in the house, and the more people who wanted to leave, the better.

Most of these turtle slaves and servant women had married in private, and according to the rules of the past, even if they gave birth to illegitimate children, they would become untouchables for the rest of their lives and repeat the fate of their ancestors. Now that they can be free, how can they not think about future generations, take advantage of the fact that the old man has not changed his mind, first get the legal identity, and then go away and fly away, even if the old man regrets it, he will not be able to catch himself back in the future.

Xinyue, who seemed to have become the big housekeeper of the Jiang Mansion, did not express her opinion, and Jiang Tian handed her a sum of silver taels two days ago, which was to deal with the current situation. In Jiang Tian's words, he will have to work in the two yamen in the future, and he has no time to manage the affairs in the mansion, and he does not know as much about the original personnel of Yihong Mansion as she does, so he handed over this important task to someone who is familiar with the inside story. There is an indescribable taste for this trust Xinyue, don't look at the fact that she has revealed her name to Jiang Tian, but that guy still habitually calls her Xinyue, instead of Feng Wanxiang, who represents more meaning.

In addition, there is an episode, there were many girls who needed to pick up customers, how many of them were so good, and some people have asked if they can redeem people in the past few days, it may be that Liu Baokai and Tian Xuhai have returned and made many people retreat, so these people didn't dare to trouble Jiang Tian, but just asked the people in the house in private. After Feng Wanxiang learned about this matter, she had an idea, and let people let out the wind, as long as it is not the girl that the master likes, she can naturally redeem it, but this can be regarded as Jiang Fu marrying the girl out, even if there is no three media and six hires, there must be a bride price, and the amount will be symbolically charged one hundred taels. This price is just five times the settling-in fee given by Jiang Tian, and it is definitely not a high price for those who can patronize Yihong Mansion. Even if someone really can't afford this price, if the girl is willing, it won't hinder other people's good deeds, but the settling-in fee will be gone. This not only saves a lot of money, but also makes a surplus!

"Does that make you think of that?" After a simple dinner, Jiang Tian really felt like he couldn't cry or laugh when he heard Xinyue report to him: "How can you be sure that they will be happy if they marry those people?" ”

Asked this question, Xin Yue, who originally wanted to hear praise, frowned: "Of course the concubine body can't be sure, even if we marry those men who treat us sincerely, it is difficult to guarantee that we will not be despised by the world, unless the master is willing to give a name, who can say for sure that he will not look away?" ”

Xinyue is talking about the essence of the problem, as the saying goes, "@ son is ruthless", but in this society that doesn't treat them as people at all, why do you ask people to be affectionate and righteous? If you don't take advantage of the fact that you are still old to find a home for yourself, do you have to wait until you are old and yellow to find a place to live? As for falling in love, love is just a means of making a living, if any girl moves her true feelings, it will be a catastrophe.

Jiang Tian didn't know how to refute, looking at her with a slight excitement, he knew that he seemed to have touched the other party's mind: "Miss Feng, don't be angry, I was negligent, but it's not that I dislike my sisters, but I don't even know how to support myself, it's really not good to drag you down." ”

In desperation, Jiang Tian had no choice but to reveal his true thoughts, and when he heard Miss Feng's title of the more angry Xinyue, he instantly turned his anger into laughter: "Mr. is really a strange person in the world, he actually worships the second grade but can't support the people in the house, and in the end, I am afraid that only Lord Hai Rui can compare." ”

Jiang Tian thought to himself what was so funny about this, it's not that I don't want to be greedy @dirt @ ask for @ bribes, it's just that the one in the Jinluan Palace definitely can't tolerate himself doing this, so it's better to be restrained in order to survive. And the reason why he developed lithographic technology alone was to apply for patents to make a little money.

"I understand what Mr. means, the concubine will definitely handle this matter." Xinyue had unconsciously changed her title back to Mr.: "But how did Mr. forget, since most of the students in the Imperial Academy have difficulty understanding your new learning, why don't you teach them separately in the mansion, so that it will not conflict with the government school, and you can collect some restraints at your discretion, presumably they will definitely rush to it." ”

Run a cram school in private! That's a good idea! This is a shortcut to the end of the income for future generations of teachers, and even if the students are willing to pay a lot of filial piety for it. In the final analysis, when high-quality educational resources are only concentrated in the hands of a few people, this kind of situation under the guise of education is actually just a disguised accumulation of wealth, and it will never be eradicated. In today's situation, there are few people in the whole country or even the whole world who can compare with Jiang Tian's knowledge level, so whether it is to tie up with the powerful or want to learn something real, there will be a large number of students who are eager for their cram schools.

After discussing this matter, Jiang Tian remembered another thing: "Miss Feng, it seems a little inappropriate to ask you now, but I have to say that except for those sisters who already have a home, I don't know what you and Linglong have planned?" ”

Originally, there were just two Qing people in the Red Mansion, and of course they were also celebrities in the capital. After the two gentlemen were rejected, there were already rumors in the market that Jiang Tian would not let go. But everyone in the house knows that this old man Jiang has never touched any girl except for the quiet sisters who have prostituted, and everyone he sees is polite and does not have a little master's shelf. However, the appearance of these two girls is diametrically opposed, Xinyue was very popular before, and after becoming the housekeeper in the house in disguise, no one has any resistance to this. Na Linglong locked herself in the room, and she hadn't seen her show up a few times during this time, except for the occasional burst of music that could be heard from her room, there was no movement. So whether these two people will be accepted by Jiang Tian or not, no one has a definite answer to this,

Xin Yue, who had just improved a little better, closed her mouth again, stared at Jiang Tian a few times and then lowered her head: "I...... There is nowhere to go for the concubine. ”

Jiang Tian didn't think much about it and said: "In that case, let's still live here, if there is a chance in the future, I will find a good family for you......"

Before he finished his words, he saw Xinyue bite her lip tightly and turn around and leave without saying a word. Only Jiang Tian, who didn't know why, was stunned there, not knowing what he said was wrong and offended her again. In fact, Jiang Tian is not really incomprehensible, there is such a big beauty serving left and right, and he has secretly enjoyed it a few times, but according to his thoughts, before he is sure that the emperor can really tolerate himself, he will not show any feelings lightly, because he doesn't want to drag anyone down, even Xiyun, who has already recognized him as a godsister, has to find a chance to marry, so as not to be unlucky with him one day. But there is one thing he doesn't know, a green building like the Red Mansion was originally a hierarchical place, don't look at everyone as untouchables, but there is still an insurmountable gap between the popular girl and the miscellaneous turtle slave. Suddenly, someone announced that from now on, these people would be the servants of an official master, and the original rank collapsed instantly, and the contradiction in it was invisibly magnified into the biggest unstable factor. What kind of eyes will those turtle slaves and servants who usually look down on even prostitutes look at the girls who have lost their jobs? Especially Linglong's guy who shrinks in the room and looks at the shadow and pities himself, do you still think that you are a popular person sought after by thousands of people? During this period of time, it was Xinyue who relied on her personal prestige to barely maintain the situation, plus the fool could see her thoughts about Jiang Tian, and in the spirit of not offending the future hostess, many people also accepted the existence of this official family. As time passed, Jiang Tian had no intention of closing the house at all, which made Xinyue's position shaken by Yan Zòng, how could she not be worried.

Although Xinyue walked out, the other two people walked over, and Jiang Tian suddenly felt a little big when he saw it, because the person who came was the quiet sister who had a skin-to-skin relationship with him.

"Two girls came to visit late at night, I don't know what happened?"

Different from her sister Youlan's slightly complaining eyes, her sister looked at Jiang Tian calmly: "The two of us want to ask the master something for some sisters this time." ”

Jiang Tian seemed to have guessed what the problem would be next: "Please speak!" ”

"I wonder if what the master said about self-determination is true?"

"Seriously!"

"Well, the two of us have discussed with some sisters, and we are willing to sell ourselves as slaves in the Jiang Mansion!"
