"This is a patent application for the lithograph method...... Jiang Tian thought about the old man Song according to the process, and submitted the application: "I don't know if the imperial court is willing to pay for this method?" ”

Song Yingxing raised his eyelids and stared at Jiang Tian, thinking that your kid wouldn't be so short of money: "Whether you buy it or not depends on the meaning of the imperial court, but I heard that there are people there who you don't want to leave the country?" ”

"You're well-informed." He also did not shy away from this topic: "It's not easy to feed a large family, so I can't find a way to earn some pocket money." ”

Thinking of the situation that night, Jiang Tian's head couldn't stop hurting, in addition to the quiet sisters, there were also several older prostitutes and some subordinates who didn't know how to live independently, all of them volunteered to stay. Maybe in their opinion, changing from a slut to a subordinate is already a great improvement, and as for things like living a civilian life, they really don't dare to expect extravagance. Or maybe they've adapted to their current life and don't know how to live independently. So they chose the path that didn't change much from their existing lives. Jiang Tian didn't directly agree to their request, but just said that he would think about it, and then secretly asked Xinyue to inquire about the real thoughts of these people before making a decision.

"Sir, sir!" After the morning class, Zhang Huan ran over again: "I heard that you want to apply for a patent for the lithographic printing method, but I wonder if it is a book printing in the future, how much will you ask for?" ”

It stands to reason that having such a diligent and inquisitive student is something that every teacher looks forward to, but every time Jiang Tian sees him, he feels a little weak, for fear that this kid will have nothing to ask some strange questions. Fortunately, there was no Jiang Tian's class this morning, but I still couldn't avoid this follower.

"I have this plan, but if no one buys this law, if ordinary people print books, I will only charge a penny for each copy!"

Patent fees are a newly established rule in the imperial court, and the main purpose is to promote the effective use of various technologies scattered among the people, and some of the more peculiar things in the province are eventually lost. However, in this era, it is difficult to ensure the normal collection of fees, even if you find out that someone is infringing, you can only sue the government to deal with it, this process is no different from later generations, but the problem is limited by the obstruction of communication and transportation, and it will be difficult to be held accountable for infringement cases beyond a certain range. As for Jiang Tian's statement that he would charge a penny, he mainly focused on the major booksellers in the capital, and the books they printed were more than 10,000 copies, as long as these people were still doing business on the ground in the capital, it was impossible not to give Jiang Tian patent fees.

After hearing the specific price, Zhang Huan couldn't help but be overjoyed: "In this way, Mr. is really generous, the student will pay a tael of silver in advance here, and I can use this method to print books in the future." ”

A tael of silver? Jiang Tian took a small silver horn and looked at it, and said in his heart Do you have a thousand books to print? Even if you have what you are going to print: "What is the content of the book that Huan'er printed?" ”

On the contrary, Zhang Huan was a little embarrassed by this question: "When the students were at home, they heard the myths and stories of Tessie told by overseas people, so I wanted to compile them into a book. ”

Western mythology does sound fresh enough, he can think that printing into Chinese can also be regarded as promoting exchanges between China and the West, but in China today, will anyone be interested in this kind of book? Jiang Tian is not sure that he can succeed, anyway, the young master of this kind of rich and noble family is not short of these two money, and those local wealth in the countryside still like to hold a poetry party or something in a vassal style, his behavior is at least worthy of praise.

"In that case, you're the first guest to pay, so I'll give you another trick."

Jiang Tian took a piece of mulberry paper used for official documents, wrote a few words casually on it, picked up a knife and cut the words on the paper neatly. This results in a hollowed-out piece of paper, and then as long as it is used as a template to cover the slate backwards, you can get a perfect inverted book, even if you can't write an inverted book, you can typeset and print it at will.

"Thank you, sir, for your teachings!" Zhang Huan, who was excited, hugged the paper and turned around and was about to run back to test, but he was careless and happened to bump into Xiyun, who was delivering food, and the two of them almost fell to the ground unsteadily. This time, Xi Yun was the only one who came, and she was carrying a basket in her hand, as if she was dressed as a country villager, so Zhang Huan was stunned and recognized her, and quickly bowed down to apologize.

When he was far away, Xi Yun came back to his senses and walked to Jiang Tian's side: "Brother, what's wrong with him?" ”

Jiang Tian can understand this, a child who is very interested in science has discovered a new toy, for the sake of the fake prince's face, he didn't say so: "Child, it's inevitable that he is not very stable." But you are disobedient, didn't I say don't travel so far to deliver food? ”

Xi Yun grinned, and regardless of Jiang Tian's complaints, she hugged the basket over, and there were two flatbreads and a few pickles in it: "Brother doesn't know, it's very strange at home now, and I'm so uncomfortable staying there." ”

The strange thing she said was that those who planned to stay began to treat Xiyun as the eldest lady in the house, no matter how much they looked down on this little girl before, now they have to do their best to flatter, and serving this aunt and grandmother is more effective than settling with Master Jiang. Of course, those who had bullied Xiyun did not dare to stay.

Listening to her words, Jiang Tian shook his head, you are too unconscious, whether you want to or not, you will be the eldest lady of this Jiang Mansion, those people must obey you, if you can't stand it now, when you find a good in-law in the future, how can you be a good young grandmother?

Thinking of this, Jiang Tian asked again: "I forgot to ask you too, do you remember your original name and surname?" ”

As soon as this topic was mentioned, the girl who was still elated just now fell silent for a moment, but when she saw Jiang Tian's inquiring expression, she didn't know how to answer him: "I...... I...... I only remember that my name was Yifang before! ”

Yifang? Is there a surname? Jiang Tian didn't turn the corner for a while, but it didn't matter: "Okay, do you want to change back to your previous surname, or follow my surname Jiang?" ”

The little girl was embarrassed again, she didn't find the weird atmosphere in the house in the past two days, Jiang Tian's promise made the people in the mansion unstable, she didn't care who left and who was leaving, just observed the expression of Xinyue during this time, she also understood that for a woman who can't control her own destiny, it's just a code name for who she belongs to, and whoever she sells to has to follow whose surname, although her brother is kind enough to let everyone change back to his original name, But not following his surname Jiang itself represents a feeling of not being accepted.

"I ...... Let's follow my brother's surname! In this way, Xi Yun has become Jiang Yifang, in this era, no one cares about such an insignificant matter, and they don't even need to go to the government to report, anyway, the new household registration system has not been formulated, you can call it whatever you like.

While the two of them were eating, Song Yi hurriedly ran over: "Sir, sir, someone in the palace has come to pass the word, let you go immediately." ”

"Gotcha! Eating is not pleasant. Jiang Tian followed Song Yi with a grumbling stomach, leaving the little girl alone in a daze.

When he came to Old Man Song's room, a person who looked like a eunuch was sitting on the side chatting with Song Yingxing, and after seeing Jiang Tian walk in, he didn't need to ask to know that everyone had arrived, after all, there were few people in the entire Academy of Sciences who could wear a red official uniform.

"Slave, I brought an edict today, asking how the two lead characters are going?"

The two of them glanced at each other, and then it was Old Man Song who spoke first: "Back to the top, the lead type is still under development, but Jiang Shaobao has recently studied a printing technique today......

Before he could finish speaking, he was interrupted by the eunuch with a smile: "Don't worry, Lord Song, your majesty already knows about the new law, and I came here this time to ask if there is anything wrong with studying lead movable type?" ”

Song Yingxing was speechless for a while, Zhang Huan and Wu Yuan were both there when the lithographic method was demonstrated that day, they must have gone back to talk to His Majesty about this matter, but when it came to lead type, this matter had always been handled by Jiang Tian, and he couldn't say what the specific difficulties were.

Jiang Tian understood what was going on at a glance, but he didn't expect Zhang Huan to be the prince, in his opinion, a water purifier was reported by someone at the beginning, and such a novel printing technique would naturally not be missed: "Although this method of lead printing is exquisite, how can the lead character not be used, and it needs to be mixed and smelted with other metals to form, but what kind of metal is smelted with it, and what is the proportion of it, there is no clue at this time." ”

The eunuch seemed to be a knowledgeable person, and after thinking about it secretly, he said: "So why don't you go to the book and show the secret." ”

Jiang Tian was right to think about it, instead of thinking about it himself, it was better to use the power of the state to conduct a large-scale alloy test to find out some metals that might be useful in the future.

After sending the eunuch away, Jiang Tian took out the periodic table that had been altered that day, and then handed it to Old Man Song: "Many of these are common metals and substances, but according to my analysis, there are more than 100 kinds of things that we have not discovered. ”

Song Yingxing watched it for a long time, he really couldn't understand why Jiang Tian would assert that there were still hundreds of things that he hadn't discovered, but he didn't dwell on this question: "In that case, you might as well write a playbook, and I'll help you polish one or two joint performances, as for whether it will be successful or not, it depends on God's will and your sincerity!" ”

Coming out of the old man Song, Jiang Tian just wanted to understand why the last song still depends on his sincerity, the world already knows that Jiang Tian is the emperor's junior brother, so he, a freshly baked and steaming junior brother, wants to engage in a large-scale scientific research activity, even if some civil officials want to refute the cost of labor and money, they must also consider the emperor's face, in ancient times, to carry out this unprecedented alloy research and development experiment, the resources required are far from comparable to later generations, so that those Taoist gentlemen understand what basic science and materials science are tantamount to playing the piano to the cow, Therefore, this matter depends entirely on the emperor's intentions, and if it is submitted to the cabinet for discussion, it will be rejected nine times out of ten. When he returned to his office, he saw that Xi Yun had not left yet, but fell asleep on his desk, and he did not disturb the girl's good dreams, but picked up the pen and began to ponder how to write the chapter in a simple and understandable way, so that the layman could understand the importance of metallurgical testing at a glance.

Jiang Tian had never written a cantata, and he didn't know what format to use, but he knew how to replace complex scientific terms with simple and easy-to-understand language, so he could only make a fuss around this angle, anyway, in the end, it had to be polished by Old Man Song, and as for those things that didn't conform to the format, please ask him to revise them. Writing freely, Jiang Tian, who had completely entered the state, didn't even notice that Xiyun had already woken up, until he threw down his pen and shook his wrist, looked at his masterpiece and nodded with satisfaction, only then did he find that a pair of eyes were staring at him motionlessly.

He reached out and patted Xi Yun's head: "What are you looking at?" ”

"Brother, it seems like a different person when you wrote just now!" The little girl seemed to be still immersed in the feeling just now: "Now he has become my brother again." ”

As for what she said about changing people, Jiang Tian didn't pay attention to it. When a person is mentally concentrated, it is inevitable that he will be different from usual: "Don't think about it, let's go home and eat quickly." ”

After handing over his work to Old Man Song, he didn't bother with follow-up questions, because the old guy knew better than Jiang Tian about the rules of how to read the book, and what to do was left to the experts to solve. Just said that Jiang Tian turned back to the door of his house, and heard that the situation was a little wrong with Boss Zhao on the other side. Turning his head, he saw that his students were standing behind a table and were at a loss for what to do, and the tea guests were coaxing in groups, completely ignoring the red face of Zhao Zhixiao on the stage. Jiang Tian, who didn't know why, didn't go home, but stood in a corner to observe the situation at the scene. I saw that Zhao Zhi still insisted on saying a word there, and he was about to cry when he looked at his expression. But the tea guests completely ignored him, chatting and chatting, drinking tea and drinking tea, and there were many people who blindly coaxed him to step down. Jiang Tian listened carefully, this kid was talking about his famous paragraph "Wax Cutting", and the performance at this time was completely out of shape, if it weren't for his thick skin and he could continue to talk step by step, I'm afraid he would have found a crack in the ground a long time ago. In fact, Jiang Tian understood as soon as he saw this situation, there are no certain rules for cross talk performances, and the same burden may not be able to shake if one person says it, and it all depends on the solid Cheng dù of the basic skills of the usual one. Besides, I haven't had a new joke for a while, and I always say that "old work" is easy to make the audience tired.

Finally finished today's performance, Zhao Zhizheng, whose face was flushed, was about to bow down and get off the stage, but he found that the teahouse that was still booing just now suddenly quieted down, and when he looked up, his master's eye-catching red official robe came into view, and now he was even more dumbfounded, such a humiliating thing made his old man look at it squarely, but how could he be worthy of the master's teaching?

If you want to say that you should find the boss to react quickly, don't look at him just now he didn't say a word, but now he squinted his eyes and scolded Zhao Zhi: "Zhi'er!" What are you doing standing stupidly? Why don't you serve tea to Mr. yet! ”

Zhao Zhi was so frightened that he hurriedly trotted all the way to serve tea, Jiang Tian was not polite, handed over the official hat to Xi Yun, and then sat behind the table under the gaze of everyone. The guests in the room looked at him stupidly, he was so faceless just now, and ridiculed his apprentice as worthless, now the master is here, and the public clothes are red and piercing, these small people in the market see a seven-grade imperial history are all bowed three times and four kowtows, this is the emperor's junior brother when the dynasty is a celebrity, the second-grade prince Shaobao, and the "Tianyuan Tea Society" plaque given by the emperor is earned by the old man Zhao...... He can't protect his calves, right?

Not to mention, even if Jiang Tian was still smiling, he just sat down like that and made the audience silent, and an invisible official authority enveloped the audience. In fact, it is not that Jiang Tian has any official authority, but that the awe of ordinary people for officials is just at work. Zhao Zhi's hands and feet were sharp, and he trotted over a teacup, respectfully placed it in Jiang Tian's hand, and then stood behind him with a teacup that he didn't dare to breathe. Jiang Tian didn't pay attention to Zhao Zhi's trembling hand, but aimed at the waking wood on the table to grab it.

At this time, it was Old Man Zhao who spoke first: "Lord Jiang has been doing business for a day, presumably he is tired, Zhi'er, don't you wait for your husband to change clothes?" ”

Old man Zhao called Jiang Tian Zhao Zhi's husband, this is already a customary rule, although everyone thinks that Zhao Zhi is his apprentice, but I don't know why, Jiang Tian is unwilling to accept the apprenticeship, so he still calls him Mr. to the outside world. Jiang Tian also reacted at this time, he was still wearing work clothes, how could he dress like this to perform, and he was not singing. So he stood up again and hugged his fists into the audience.

"Wait a while for the rank of official, and the official will come when he goes!" As he spoke, he walked towards his own house on the other side.

He's gone, and the tea guests are all stupid, what does that mean? Could it be that Master Jiang still has to say something? Everyone thinks that he is now a very good minister, how can he still come here to do such a cheap thing. But look at today's meaning to find a field for his apprentice, the people who originally wanted to take the opportunity to slip away can't walk at this time, Jiang Tian used to be a poor show to eat this bowl of open rice for a living, and now what is the identity of the person, even if you want to be troubled today, you have to stay, and a court official will give you the opportunity to say cross talk, which is difficult to find in the world. Mr. Liu, who was going to appear to tell the story, didn't dare to come out, and he also wanted to hear what new jokes he had. Jiang Tian changed his clothes very quickly, and returned to the teahouse in a robe without a crown, and then stood behind the desk with the appearance of the young scholar.

"The horse is thin and has long hooves and fat hooves, and the son is not a thief when he steals his father. The blind uncle married a blind grandmother, and the two of them have lived most of their lives, and no one has ever seen anyone! With a soft laugh, Jiang Tian picked up the Xingmu and patted it gently: "Smack!" Let me tell you a final poem first, why do you say this, this is to cage your ears, so that you can all listen to me cross talk......"

His opening statement was obviously plagiarizing Mr. Liu Baorui, but fortunately, the main owner was not born yet, and no one sued him for infringement. Besides, this also has the element of educating Zhao Zhi, in fact, as long as he goes to this station, not to mention that he doesn't need to recite poetry, or he doesn't even have to shoot Xingmu, the audience will naturally focus all their energy on him. Even those subordinates in Jiang Mansion also ran out at this time and listened with their ears far away, and their master said cross talk again, how could he miss this opportunity.

“…… Is this limerick poem in front of me a joke or not? It's not like a blind uncle marrying a blind grandmother, but no one has ever seen anyone! But that's not the most cola, I know that......"
