It snowed heavily in Guanzhong for three days, and the sky was overcast on this day, and there were three more pandas in the house.

This short-tailed creature is very fond of Xiao Qingqing.

Before going to the class, she told Xiong Er and Xiong San not to bully the new three red pandas.

The ancients called this kind of creature a lot, and the Book of Poetry has a white saying, and I don't know if this white creature refers to them.

There are many records of pandas in the classics of the Central Plains, and their traces span the changes of various dynasties throughout the Central Plains.

They are not like the brown bears at home who can eat soup and rice, Zhang Yang feeds them with melons, fruits or vegetable leaves in the greenhouse, and they eat deliciously.

There are also bamboos in Guanzhong, and there is a small bamboo forest to the south of Lishan.

The daughter had already sat down on the bear's back, and Zhang Yang took her down the mountain, "Let's plant a bamboo forest in Lishan in the future." ”

"Do you want to give the three new bears bamboo to eat?"

"Well, you can't always keep them at home, you have to let them adapt to the environment."

Xiao Qingqing also learned to shake her hands like her father, and before she knew it, she also had this habit, there is a way that parents are like, and children are also like.

The appearance of the father and daughter going down the mountain together is very interesting.

Although Xiao Qingqing was brought up by this bear, he became more and more like his father and mother in words and deeds.

Walking down the mountain, Xiao Qingqing shrank his neck in the cold wind and said with his hands in his hands: "Daddy, I don't want to learn medical skills." ”

"You don't need to be proficient in medical skills, you can just learn some common sense of medicine."

"I don't like Doctor Sun either."

The daughter is a little stubborn.

Zhang Yang said patiently: "Recently, Doctor Sun has been very busy, and he has not had the leisure to teach you medical skills, so he doesn't need to learn these two days." ”

When she arrived at the door of Li Jing's house, Xiao Qingqing sensibly went to practice her fists and feet with the Red Whisk Girl, her little short legs followed the movements of the Red Whisk Girl to practice kicking, and the Red Whisk Girl asked her to rest her legs on the wooden frame to stretch her muscles and bones, a bit like learning ballet leg presses.

The weather was cold, and General Li Jing also put on Lishan's unique cotton clothes.

His eyes also looked at one big and one small practicing his fists and feet, and when he spoke, his mouth kept spitting out white mist in the cold air.

"Can the firearms be cast?"

Zhang Yang heard the general's question, leaned his back against the wall and looked at his daughter and replied: "It will take some time, the general doesn't need to worry." ”

Li Jing also watched Xiao Qingqing's movements, "This little doll's talent is good, but women don't need to learn martial arts." ”

Zhang Yang smiled: "Let's let her learn, her mother gave her a lot of expectations, if she learns well, she can use it in the future to fight, and it can also be used for self-defense, and if she doesn't learn well, it will be regarded as a talent." ”

"Well, you're very tolerant of your own children."

"Her mother is very strict with her, I need to give her some tolerance."

After sitting at General Li Jing's house for an hour, Xiao Qingqing's class here also ended.

Zhang Yang asked his daughter to say goodbye to Li Jing and his wife, and then took her to Mr. Ouyang Xun's house to learn calligraphy.

"Dad, I want to eat barbecue."

"No, I've already eaten it this month."

As soon as the words fell, she looked unhappy, and Zhang Yang said in a low voice: "That's it, I'll ask your Uncle Wei Wang to send it." ”

"Good!"

"Don't let your mother know."

"Hmm!"

sent his daughter to Ouyang Xun's house, asked her to learn calligraphy with this calligrapher, and asked Li Tai's guards to pass the word.

Not long after, Li Tai brought two skewers of mutton to her little niece.

Zhang Yang first finished eating one of the bunches and left one bunch for his daughter, "If your imperial sister knows, she will be punished." ”

Li Tai scratched his head and said in distress: "The imperial sister is too harsh on Xiao Qingqing. ”

Xiao Qingqing has been deeply favored by the emperor since she was born, and then she has a lot of property, the best care, and the most favored identity, and her teacher is a first-class figure in various fields, and the future of this doll is limitless.

Zhang Yang looked at Li Tai's expression again, and he didn't know if he had been negligent before, but he always felt that after this fat man got married, his complexion was better.

The weight loss effect is still not obvious as always, verbally insisting on weight loss, and behaving as gluttonously.

Li Tai whispered, "Brother-in-law, have you heard?" ”

"Well, what did you hear?"

"This year, Yu Shinan resigned again, and his father agreed."

"Really?" Zhang Yang bowed his head and said: "I remember that this is not the first time that Mr. Yu Shinan is about to resign." ”

Li Tai glanced around and whispered, "It's just that there have been some other voices in the court recently. ”

"Mr. Yu Shinan is so old, is there anything wrong with him resigning?"

"If it's just Mr. Yu Shinan who wants to resign, then that's it, it's just because there was another incident before the resignation this time, the Xu family in Jiangnan Dongdao has already sent a piece of music to the DPRK and the central government."

"So this time, some people are also talking about whether Mr. Yu Shinan's resignation is related to the tea dispute of the Jiangnan Wang family."

Mr. Yu Shinan is also a branch of the Jiangnan Wang clan, and if he is used by someone with a heart, he really can't tell.

Zhang Yang glanced at the courtyard, Xiao Qingqing was writing with a pen, learning the way Mr. Ouyang Xun moved the pen, writing one stroke at a time.

This is the best calligraphy teacher, I don't expect my daughter to learn how well, she just needs to learn to write beautiful and neat handwriting.

Zhang Yang felt that his retirement life was approaching him, took his daughter to class, and was busy with the affairs of Taifu Temple in his spare time.

When her daughter's half-hour calligraphy class is over, it's time to go home for lunch, and the afternoon time is her own, and her daughter is still young, so she doesn't have to put too much pressure on her.

Zhang Yang handed her the kebab in his hand, "This is from your Uncle Wei Wang." ”

Xiao Qingqing happily took the lamb skewer and chewed it in his mouth.

Zhang Yang said in a low voice: "After eating, go back to the mountain." ”

Xiao Qingqing couldn't help nodding, and ate this string of mutton in three or two bites.

I only left her a bunch to leave some stomach to eat at home.

She cleverly wiped her mouth clean and let the bear carry her up the mountain.

At this moment on the mountain, Xiao Wu and Xiao Hui, as well as Li Lizhen, are still practicing riding and archery.

I heard Aunt Yang say that when they pulled the bow, their arms did not have so much strength, which limited the accuracy and range.

Zhang Yang thought of the current structure of the Tang Dynasty's bow and arrow, and after lunch, he looked at the bow and arrow when they practiced riding and archery.

After trying to pull the bow and arrow away, Zhang Yang nodded slightly, and there was a direction of improvement in his heart.

In addition to taking his daughter to school, Zhang Yang is busy in the workshop these days.

Today is the winter solstice, Li Yue sat by the Huaqing Pond and waited for noon, as soon as noon arrived, he recorded the sunshine angle, and then calculated the calendar according to the stars at night.

The studies of the younger brothers and sisters on Lishan were also handed over to Xiaohui and Xiaowu, and the husband and wife were busy with their own affairs.

Zhang Yang took half a month to make two bearings, because of the relationship between manufacturing accuracy, Lishan's bearing style is based on his own improvement.

The internal rolling element is not a steel ball, but a cylinder made of fine iron, and some tung oil can be used.

Three bearings of different sizes are the key to connecting the steam engine to the lathe.

In fact, the casting of bearings is not difficult, and it is rare to polish the roundness of the rolling elements inside the flywheel ring.

"Is this also the key to Lishan's production?"

Zhang Yang nodded and said, "Don't look at this thing, it's not complicated, I spent a lot of iron for this component." ”

Zhang Yang put the five bearings of different sizes on the table and looked at the drawings.

In a certain sense, Li Tai's understanding of the transmission device is good, but he mostly uses straight line rotation, according to the transmission principle, with the lengthening of the lever, the force on the rear end will be greater.

If you only lengthen the lever to improve the operating efficiency, according to the law of conservation, the force will not increase for no reason, and the force will be halved when the force reaches the rear lathe.

This is the same as the principle of the flywheel lathe used by themselves, every time the coil is stepped on and rotates a circle, but the flywheel only rotates half a circle, and the repeated pedaling effect makes the flywheel rotate faster, so as to do work under the inertia of centrifugal force to achieve the speed you want, and do some cutting and grinding work.

When another heavy snow fell on the winter solstice, there was a cheer from the factory, the steam engine was connected to the lathe, and the semi-automatic mechanization of the entire factory took a big step.

And on this day, Li Tai invited Yan Liben to come and observe.

As Li Tai's father-in-law and a potential partner of Lishan in the future, Li Tai explained to him many of the principles used in the factory.

Yan Liben looked at the assembly line in front of him, and manually wound the cotton thread on the lathe line and put it into the lathe, and the steam engine roared and rotated the connecting rod to drive the lathe to rotate.

For this old craftsman, it was the first time he had seen such a complex assembly line, all kinds of rivets, springs, and newly made bearings, all of which were processes he had never seen.

Yan Liben found the oldest craftsman here.

Master Jiang said: "The county marquis of Lishan is Xiao Zhang, as early as seven years ago, the old man found the clue when he first saw his craftsmanship, maybe others will not seek to improve if they have higher skills, but Xiao Zhang is bent on creating these." ”

Rather than listening to Li Tai's introduction, Yan Liben was more willing to listen to this Master Jiang's narration, "This elder, with all due respect, the fabrics made by such an assembly line are all the same, which goes against the purpose of craftsmanship. ”

Master Jiang said with a smile: "Don't you talented people often say that they are different and do not conspire with each other? ”

"Old man, I haven't read any books, but I also know what the people need, what Lishan wants to make is only cloth, these cloths are cheap but can be supplied to thousands of households, and the old man also heard that the army wanted to buy it several times but was refused, because the productivity of Lishan is not enough."

"How much cloth can one person weave with one needle? Excellence is the ideal of craftsmanship, but is it really correct to blindly pursue the level of craftsmanship in workmanship and weaving, without seeking flexibility? For many years, since Lu Ban's defeat, it is difficult to see any more ingenuity in the world. ”

"If more people are willing to buy Lishan cloth, then it also deserves to be rich, this is the choice of the world, isn't it? Lishan was not cast to please the emperor, not for the selfishness of the powerful, he used all his manpower and material resources for the production of Lishan and for the needs of the people. ”

Yan Liben frowned and glanced at the assembly line again, and there were all kinds of thoughts in his heart, a kind of loneliness and helplessness.

By feeding coal and stone to the steam engine, these silk threads can be woven into cloth, and a roll of smooth wool cloth is produced, and the wool cloth is very thick and rough, but it is also suitable for heating.

It is not as silky as silk, nor is it as light and thin as silk, and thick cloth is inexpensive and can keep warm.

Li Tai held a roll of cloth and said with a smile: "The assembly line designed by my brother-in-law before was remade on the basis of the current appearance, and when our factory is more spacious, we can make more cloth." ”

Facing his father-in-law, Li Tai spoke enthusiastically about everything here, and even talked about his perception of electromagnetic aspects these days.

Yan Liben knew nothing about it, as one of the top craftsmen in the Tang Dynasty, but there were also things in Lishan that he couldn't understand and couldn't understand.

Master Jiang said in a low voice: "According to the experience of the predecessors, how long has the craftsman been standing still, if he can accept the experience of Lishan casting, the old man thinks that it is another world." ”

These words echoed in Yan Liben's mind, whether the road to Lishan was the right way, Yan Liben still had doubts in his heart.

He followed King Wei to see his daughter and asked many things before he left Lishan with confidence and returned to Chang'an to continue to supervise the construction of Taiye Pool

On the other side of Lishan, there was an explosion.

I was very curious about these small artillery battles before, but now Li Jing is playing with these bamboo cannon battles, watching them explode and the gravel blow up in all directions.

I was surprised by this scene before, but now I feel bored after watching it too much.

He looked at Zhang Yang, who was lighting the fuse bomber, and said the words that he had asked countless times in Lishan, and said in a low voice: "When will the old man see the real firearms." ”

Zhang Yang covered his ears, and the artillery exploded again.

The Red Whisk Girl and Li Yue watched this scene not far away, Xiao Qingqing didn't have too much surprise when she looked at the artillery battle, she sat on the bear's back and covered the bear's ears, and there were three pandas on the bear's back.

The two families took a walk by the bamboo forest in Lishan, and by the way, they took General Li Jing to get acquainted with Lishan.

Li Jing and other firearms have been waiting for two months, entering Lishan in late autumn, and then in the cold winter now.

"Please wait a little longer, General."

Li Jing lit a cannon battle in his hand and threw it into the distance to watch it explode, "Wouldn't it be better for you to make a bigger artillery battle?" ”

"There are a lot of small creatures hibernating on this mountain, so it's not good to disturb them."

Li Jing looked sideways at the bear, which was so strong and big that it was half a human's height when lying on the ground.

Zhang Yang explained: "My daughter didn't let this bear hibernate, and it was dragged out of the house, and it has already accepted its fate. ”

Li Jing wanted to speak and stopped, but sat down and drank tea, there was still some snow on the mountain, and the scenery here was very beautiful.

The emperor did not come to Lishan for the winter, so Lishan had a very easy time in this winter.

"The old man heard that after Goguryeo was defeated, there was a lot of controversy between the DPRK and China about governance."

"Please also ask the general not to talk about the affairs of the court, I am now the Taifu Siqing, but ask these major events, isn't it good to live our retirement life?"

Zhang Yang put the artillery in his hand into Li Jing's hand, and said excitedly: "Come on!" Then fry it, how much fun. ”
