Time passed quickly, and it was about to come to Li Shimin's jet lag printing factory, and fifty printing presses had been rushed out by craftsmen and sent to the paper mill. Changsun Chong also experimented with each machine the day before to ensure normal use.

And Li Shimin took the ministers out of Chang'an and visited the paper mill before he went to the early dynasty.

After entering the paper mill, everyone can see the difference inside the paper mill. The paper mill was divided into two halves by Changsun Chong, one side was the paper mill that he had been to before, and the other side was built by Changsun Chong and built a lot of houses, which became the current printing department.

The eldest grandson Chong took Li Shimin and the ministers to the printing department, and when he entered the house, he saw the printing press placed in the house and the three people who operated the machine, and the cut paper was neatly placed next to it.

"Your Majesty, everything is ready, the main book to be printed today is the Analects, and please give Your Majesty the order to begin." The eldest grandson Chong said to Li Shimin.

"Don't worry, I'll take a look at this machine first!" Li Shimin took his ministers to look at the printing press, the whole printing press was made of some wood and iron, wood accounted for 90 percent, and the workmanship was very skillful.

"Your Majesty, Qin Feng said that the service life of this printing press is about one year, because the wood is easy to deform after a long time, and it will be inaccurate after a long time. Therefore, Qin Feng suggested that the printing press should be replaced regularly every year. The eldest grandson Chong said to Li Shimin on the side.

"Can such a good machine last for a year? Is there a way to extend the day? Fang Xuanling said after hearing this.

"I don't know about this, I have to ask Qin Feng!" The eldest grandson said to a few people.

"Qin Feng, this kid really has a hand in the way of things! By the way, what about Qin Feng's kid? Li Shimin looked at it and asked the eldest grandson.

"Qin Feng didn't come over, Qin Feng said that he is now a grass farmer, and it is not appropriate to come here on this occasion." Changsun Chong said.

"Ridiculous, this kid, he can't come, who explains this machine to me, go, send someone to call Qin Feng to me." Li Shimin said to the eldest grandson Wuji.

"Your Majesty!" The eldest grandson called the guards happily and instructed the guards, it seems that Li Shimin has not given up on Qin Feng.

"Tut-tut, this machine sits so delicately, the old man can't do it even if he wants to break his head." Fang Xuanling touched his beard and said to everyone.

"Don't talk about you, even I, the secretary of the Ministry of Industry, have never seen such a delicate machine, I'm afraid that those craftsmen in the entire Ministry of Industry can't think of it, you see, so exquisite, who can think of this?" Zhang Liang, the secretary of the Ministry of Industry, also said with a smile.

Those people from the family were shocked when they saw these machines, but they still didn't stop them, looking at the situation, Qin Feng had already made printing machines before he was imprisoned, and it was useless to be anxious now.

"Chong'er, let them start." Li Shimin said to the eldest grandson.

"Your Majesty!" After Changsun Chong finished speaking, he walked to a place by the wall, there was a rope on the side of the wall, and when Changsun Chong pulled it, the bell sounded in the entire housing area in the printing area, which was also designed by Qin Feng, in order to give an order to the same family, each housing square used a rope to wear this bell, as long as the house was pulled, the bell of each room would ring, which was also the signal of the beginning.

"Click!"

"Click!"

In an instant, there was a clicking sound in the factory area of the entire printing plant, Li Shimin and others watched from a blank paper in, embossed it, the person in the middle turned it over and put it on the other side, printed it again, and a piece of white paper was printed, and it was put in a frame and put it in order.

Then I saw the workers working at a very fast pace, and in less than three breaths, a blank sheet of paper was printed.

"So fast!" Rao is eldest grandson Chong informed Li Shimin in advance, and Li Shimin was still shocked by such a speed.

"This is printed?" Fang Xuanling picked up the printed paper and looked at it quickly.

"This speed is so fast, how much can be printed in a day?" A Wenchen said with his mouth wide open. But no one paid attention to him at this time, and in the eyes of others, this printing press was much, much faster than hand-copying.

"Chong'er, what about this discontinuity? Is it a typo? Fang Xuanling, who was watching, asked the eldest grandson.

"Uncle Fang, this should be seen together, you see, this is the first page, and the reverse side is the second page. The content of these two pages is sequential. Changsun Chong said as he flipped through the paper and explained to everyone.

"Ah, how amazing is it? So, these two times are 286 pages printed? Li Shimin also picked up the paper and saw it.

"Yes, Your Majesty! If there are enough 100 copies printed here, someone will come and pick them up, and then cut and bind them to the size of a normal book. The eldest grandson Chong explained to everyone.

This speed was so fast that it didn't take long for a hundred sheets of paper to be left next to the press, and then someone came to take the printed paper to the side and cut it. The cut paper is arranged in pages, and a worker takes one sheet of each page in order, then puts it on the hole press to punch holes, and then ties it with hemp rope and puts it on the shelf in front, and a finished book has been bound.

The eldest grandson Chong took a few bound books and returned to hand them to Li Shimin, Fang Xuanling and others.

Li Shimin and others took the book and began to look through it, wanting to see if there were any errors or omissions in it.

"Your Majesty, uncles, don't look for it, there is nothing wrong in it, and the typesetting before printing must be checked three times to ensure that each book is not printed and there are no errors. This was also requested by Qin Feng. The eldest grandson said to everyone, not forgetting to give Qin Feng the credit.

"It's good, it's good! You just have to be serious. Well done. Li Shimin said with a smile.

Li Shimin smiled happily, but the people of the family were all green, and after a while, hundreds of copies were printed. If you want this printing house to continue printing, I am afraid that it will not take a year, and the entire Datang will not be short of books, and those bamboo slips can be used to print paper.

At this time, the guards came to report, and Qin Feng brought it, just outside.

"Bring it in!" Li Shimin commanded.

A moment later, Qin Feng was taken to the printing workshop by the guards and saw Li Shimin.

"Grass people Qin Feng greets Your Majesty!" Qin Feng bowed and saluted, he had just gotten up today, and he was just about to go to Qinling to build a cave after dinner, but he didn't expect to be stopped by the guards as soon as he left Qinzhuang, saying that Li Shimin wanted to see him. I had no choice but to follow to the paper mill.

"Get up!" As soon as Li Shimin opened his mouth, he fell towards Qin Fengshu.

"I don't know what His Majesty called the grass people!" Qin Feng asked.

"Chong'er said that these machines can only be used for one year, can you extend it for a while?" Li Shimin asked at Qin Feng.
