Zhu Youzhen waved his hand and asked Fu Xiaojian to step back, he saw an old man who was a little rickety, came to the inside of the gate, and blocked the gate, "This old man, why did you speak to prevent me from entering the school?" ”

"You don't look like you're from the academy," the old man glanced at everyone, and then his gaze stayed on Zhu Youzhen's body, "They are from the academy, of course they can go out freely." ”

"That old man is ......"

"I'm the gatekeeper of the academy," the old man straightened up, trying to stand up straight, "Any outsider who wants to enter the academy must first reveal his identity. ”

Zhang Yixian rushed up, and was about to drink a few words, when he saw Zhu Youzhen waving his hand, he had to point to his eunuch hat, and the old man was suddenly frightened like earth, "poof", and fell to the ground, "Grass people should be damned......"

Zhu Youzhen stepped forward with a smile and helped the old man up, "Uncle, there is nothing wrong with your loyalty to your duties, don't worry, I'll come to your dean." ”

"Dean?" The old man came to his senses from his daze, "Dean Xu is not in good health and is recuperating at home. ”

"Is Dean Xu's family hospitalized?"

"In the courtyard, since a few people are from the palace, what ...... Please come with me! The old man was in front and led Zhu Youzhen and the others into a gray-white hut, "This is Dean Xu's home, he is not in good health, he should be at home." ”

"Thank you, sir." Zhu Youzhen bowed to the old man.

The old man returned the salute, "No, Dean Xu is not in good health, you have to leave early." ”

A guard reported first, and after a while, he came back, "Your Majesty, Dean Xu is invited." ”

This Xu Guangqi, so he didn't come out to greet him? But Zhu Youzhen never cared about etiquette, so he didn't think much about it, and under the guidance of the guard, he entered Xu Guangqi's inner house.

"Your Majesty......" Xu Guangqi was trembling up from the bed, and an old woman was holding Xu Guangqi's arm.

"It's not good to be in good shape, so you don't need to be polite!" Zhu Youzhen took two steps and pressed Xu Guangqi on the bed.

"Then ......" Xu Guangqi leaned on the quilt and kicked his breath, "Your Majesty ......"

"How's Guangqi's body?" Zhu Youzhen found that Xu Guangqi's body was extremely bad, otherwise it would be impossible for him not to greet him.

"Your Majesty, grass people...... The grass people are fine, the old problem is ...... Guilty of ......"

Seeing Xu Guangqi so seriously ill, Zhu Youzhen couldn't bear it, but his academy was his last hope, he bowed to Zhang Yixian, and Zhang Yixian took out the chime bell and drawings from his arms.

"Guangqi, this is the chiming bell I got from the Westerners by accident, and there are production drawings, can the Academy of Sciences copy it?"

Xu Guangqi stretched out his rugged right arm, took the chiming bell, fiddled left and right, then put it at the head of the bed, took the drawings again, and glanced at it quickly, "Your Majesty, grass people...... Not proficient in these things, but John Tang of the Academy of Sciences ...... Proficient in machinery, Your Majesty is here for the time being, grass people...... Let John Tong ...... Try it, maybe you can make it. ”

"John Tang?" Zhu Youzhen muttered, this name is so familiar, but he can't remember who it is for a while. “

"Your Majesty, John Tong...... is sacred...... Roman Empire ......"

Zhu Youzhen understood, another missionary, a well-known missionary, "Guangqi's body is not good, take care of his illness first, and then talk about this later." ”

"Your Majesty, rest assured, grass people...... It's okay......"

"I will go back to the palace first, it is important for Guangqi to recuperate, and the matter of ringing the bell is not in a hurry." Zhu Youzhen left Xu Guangqi's home, left the Academy of Sciences, and returned to the Qianqing Palace.

Cai'er told Zhu Youzhen that Liu Qianzhi had come to him early in the morning.

"This Miss Liu is really impatient, let her come over in the afternoon!" Zhu Youzhen said to Zhang Yixian: "Let people go to the market to buy back 100 catties of cooked cotton, and then buy one of each kind of spinning wheels, well, and buy some wood and tools to make spinning wheels." ”

"Yes, Your Majesty." Zhang Yixian led the order and left.

"Your Majesty, are you really renovating the spinning wheel in this Qianqing Palace?" Cai'er raised her little face, looking puzzled.

"Well, just let Miss Liu fiddle in the warm pavilion, I have to give me some pointers at any time, it's more convenient."

Zhu Youzhen hurriedly had lunch under the service of Zell, and hurried to sleep for a while, and when he got up, it was already the end of noon.

Cai'er has been staying by Zhu Youzhen's side, and when she saw Zhu Youzhen open her eyes, she was blessed, "Your Majesty, Gonggong Zhang bought back the spinning wheel and other utensils, and sent them to Miss Liu." ”

"Oh, go check it out." Zhu Youzhen was served by Cai'er, dressed up, washed his face with cold water, and then came to the warm pavilion where Liu Qianzhi temporarily lived, accompanied by Cai'er.

Liu Qianzhi was fiddling on a spinning wheel, her head was covered with snow-white cotton wool, Cai'er wanted to say something to remind, Zhu Youzhen stretched out her hand to stop her, but she still couldn't help laughing out loud.

"The people's daughter knocks to see Your Majesty!" Liu Qianzhi looked up and saw Zhu Youzhen, hurriedly put down the cotton ball in her hand, leaned down and bowed down in front of Zhu Youzhen, "The people don't know that Your Majesty has arrived ......"

"Alright, get up!" Zhu Youzhen waved his hand, and he also laughed in his heart, "This, Miss Liu, do you have eyebrows?" ”

"No," Liu Qianzhi got up from the ground and shook her head slowly, her big eyes full of despair, "Your Majesty, don't say eight spindles, not even two." ”

"Ao, does Miss Liu know how to spin?" Zhu Youzhen looked at Liu Qianzhi's white fluff, like spores on tofu, not like she could spin at all.

"Your Majesty, the maiden has been spinning since she was eight years old." After Liu Qianzhi finished speaking, she was also waiting for Zhu Youzhen to answer, and sat down in front of the spinning wheel, and spun cotton in style, but there was only one spindle on the spinning wheel.

"It turns out that Miss Liu really knows how to spin." Zhu Youzhen saw that Miss Liu's hands and feet were still dexterous, and he no longer doubted her skills, so he set his eyes on a few spinning wheels.

There are a total of four spinning wheels, each with different structures, both the most old-fashioned frame wheel, and the latest spinning wheel, Zhu Youzhen can't even name it, this is like a rectangular frame, in the lower part of the center of the frame, is a horizontally placed spindle.

"Miss Liu, you've already tried, what's the problem?"

"Your Majesty, the folk girl tried to add two spindles, but every time she spindle, either the yarn was mixed together, or the thread was broken, which was slower than one spindle." Liu Qianzhi threw her eyes for help to Zhu Youzhen.

Zhu Youzhen followed Liu Qianzhi's gaze and found that Liu Qianzhi was a little depressed.

On the tender little face, there is some reddish in the paleness, and the green flower pleated skirt on the body is soaked with sweat and wrapped around the body, fully exposing the graceful curves of the upper body.

Zhu Youzhen's gaze stayed for a moment in the place where she shouldn't be looking, not wanting to be discovered by Liu Qianzhi, she glared fiercely, and Zhu Youzhen had to withdraw her gaze, "Miss Liu, you can spin two more spindles." ”

"Yes, Your Majesty." Miss Liu quickly wiped away the anger on her face, and sat down on the small square stool, which had already been added by her to a spinning machine.

The two spindles are connected to the cooked cotton in a flat-bottomed wooden box, and there is no baffle on the side of the wooden box facing the spindle.

Liu Qianzhi only spun a sip of tea when a cotton yarn broke, she stopped what she was doing and looked at Zhu Youzhen with a blank eye, "Your Majesty, these are only two spindles, and the folk girl has been watching for a long time, it can't hold eight spindles anyway, let alone fifteen." ”

Such a speed is obviously not possible, and there are only two spindles.

Zhu Youzhen walked around the four spinning machines, and his mind was quickly looking for information about Jenny's spinning machine, and he suddenly remembered the story of Jenny's spinning machine.

The story is as interesting as why the apple fell on his head, so he still remembers it clearly.

The inventor of Jenny's spinning machine is a man, his wife is a spinning lady, because he accidentally knocked over his wife's spinning machine, he hurried to help, but he was surprised to find that the spinning wheel had overturned, but the spindle was still rotating, it turned out that the spindle was placed horizontally, and now the spinning wheel has turned over, and the spindle has become vertical.

He was pleasantly surprised to find that if the spindles were placed upright, the number of spindles could be increased! As soon as he said it, he modified a spinning machine that could hold eight spindles overnight, and named the spinning machine after his daughter's name "Jenny".

Here's the answer.

Zhu Youzhen suppressed the secret joy in his heart, he circled around the four spinning machines again, and finally stopped in front of the latest spinning machine.

This spinning machine with a rectangular frame structure only has one spindle in the center, which looks empty, "Miss Liu, install a fixed rungs in the middle of this spinning machine, and then fix eight iron buttons from left to side on the rungs, and one spindle can be placed on each iron button. ”

"Vertically?" Liu Qianzhi scratched the "white hair" on her head with her hand, "Your Majesty is saying that the yarn spindle should be placed vertically?" ”

"Yes, put it vertically, otherwise there will be no way to place so many spindles, and," Zhu Youzhen squatted down and gestured at the place where the spinning wheel was in neutral, "After being placed vertically, these cotton yarns will not be mixed together." ”

"Huh? The folk girl understands, it's really damned, why can't I think of it? Liu Qianzhi patted her head, ignoring Cai'er's mocking gaze, lowered her head and began to modify the spinning machine.

"Miss Liu, you fiddle slowly, I still have to go out of the palace." Zhu Youzhen only provided ideas, knowing that if he continued along this line of thought, there would definitely be results, but specific modification and operation were not his forte, just like the relationship between science and technology.

Besides, he doesn't have so much time, he has to do everything himself, so he will be so busy that he can't take care of eating, so let the lovely Miss Liu find a sense of existence.

"Your Majesty will be busy first, and the folk girl will modify this spinning wheel first," Liu Qianzhi put down the work in her hand, she had already regarded Zhu Youzhen as a mentor, "If the modification can't be successful, can the folk girl go to His Majesty for help?" ”

"Of course you can, as long as I am in the Qianqing Palace, Miss Liu can come to me for help at any time," Zhu Youzhen looked at Cai'er beside him, "Remember, unless it is to meet with important ministers in the court, Miss Liu will come over in the future and report immediately." ”

"Yes, Your Majesty." Cai'er wondered in her heart, this Miss Liu, just a people's daughter, with a wealthy family, how could she get His Majesty's favor so much? Where did she know about Zhu Youjian's "Industrial Revolution #Life" plan.

Liu Qianzhi smiled gratefully, looked at Zhu Youzhen with blank eyes, and didn't know what she thought, she suddenly blushed, pursed her mouth, twisted her neck, lowered her head and quickly fiddled with the spinning machine.

Zhu Youzhen asked Cai'er to leave two palace maids to assist Liu Qianzhi, and then dialed two little eunuchs to help with the purchase, and then left.
