The aunt had already prepared the meal, the children were eating, and Li Yue sat down with her long hair like a waterfall.

Xiao Qingqing's appetite is particularly good today, holding a small spoon, and his hands are still heavy to send food to his mouth.

Li Lizhen and her younger siblings ate quietly.

Just after tasting it, Li Yue frowned.

Aunt Wang whispered: "Your Royal Highness Princess, is it unappetizing?" ”

Li Yue whispered: "Is there not enough salt at home?" ”

"Is it too bland?"

She nodded slowly, looking at the bowl of porridge with a solemn expression.

Zhang Yang ate happily, "It's just right to be salty." ”

Li Lizhi just finished eating and put down her chopsticks, "Well, Auntie's craftsmanship is getting better and better." ”

"Your imperial sister's taste is getting heavier and heavier these days." Zhang Yang picked up a salted duck egg, peeled the shell and put it in her bowl, "Stir the salted duck egg and eat it." ”

A mouthful of porridge with salted duck eggs in the mouth, Li Yue nodded, "Well, it's much better this way." ”

Compared with the calm Lishan Mountain, in the late autumn season, in Chang'an City, the genius has just opened up, and Suzaku Street is very lively.

Pei Xuanji came to a house in Chang'an City, which was located on a street corner in Tongshanfang, and it was still quiet when he passed through the lively Suzaku Street.

There are also a lot of Buddhist disciples here, since the original Shengguang Temple collapsed in a thunderstorm, many monks have nowhere to go but to stay in the streets and alleys.

Glancing at these monks with annoyance, Pei Xuanji just wanted to marry a girl with five surnames, and then enter the official career and become a member of the Wang family.

When I pushed the door in, I saw Li Zhengzao looking at a book in the courtyard, and the old monk Huikuang was sitting in the house meditating.

The purpose of coming here is to talk about the situation and the current situation.

The current situation is that early this morning, there are several carriages at the entrance of the village of Lishan, and the carriages are full of silver money, and they sent people to inquire before they found out that there are 200,000 yuan, which is the fixed money for the Khan to buy the papermaking technology of Lishan.

"Don't worry, if you want to marry a woman in the clan, the old man can say a word." Li Zhengzao said leisurely.

As for what kind of woman she marries, or whether she is a woman with a child, it is not up to Pei Xuanji to choose.

There are too many people like him, and women with five surnames don't worry about getting married.

"Old gentleman, early this morning, I sent someone to Lishan to inquire about the situation, it is said that it was the money given by the Khan of Tian, and he gave us twice as much."

Hearing this, Li Zhengzao stroked his chest, only feeling a faint pain in his heart, 200,000 yuan, this is not a small number.

Pei Xuanji stood quietly aside, observing the other party's expression.

The monk Huikuang in the house spoke: "It's just 200,000 guan, according to Lishan's meaning, as long as whoever has more money, he will give it to whom." ”

After reciting the Buddha's name again, the monk continued: "Zhang Yang is a mercenary person, he will also destroy himself because of his greed, everyone in this world has weaknesses, he will not be an exception." ”

Li Zhengzao lost the mind to read, listened to the old monk's preaching, and put down the scroll in his hand, "The old man can't take out so much money." ”

Monk Huikuang stood up, closed his eyes with a devout face, and chanted a Buddha name, "As long as the silver money is more than the heavenly khan." ”

Li Zhengzao hesitated: "Tongguan's 100,000 guan is already the old man's entire family. ”

"Buddhism can produce another 200,000 runs, all for the world, and the old monk asked the temples around the country to arrange."

Pei Xuanji looked at the expressions of the two of them, everyone looked like they were separated, each had their own thoughts, and they also had their own plans, and no one was convinced.

Because of papermaking, Li Zhengzao joined forces with Buddhism to take Lishan.

Monk Huikuang walked to the house, and a group of monks outside quickly stood up and showed a pious face.

"It is our duty to eliminate evil in the world, and it is not so difficult to deal with Lishan, especially Zhang Yang's others."

As the old monk spoke, his voice getting farther and farther away.

Pei Xuanji stood in place and whispered, "Why does the old gentleman have to walk with these people. ”

Li Zhengzao bowed his head and said, "Do you think that the old man can't see their intentions?" ”

"I understand that the old gentleman can't help himself, and he is a burden of family history, so he can only make this decision."

Li Zhengzao bowed his head and said: "The old man has always been poor, and they are the most greedy people!" ”

Pei Xuanji nodded slightly.

Lishan, the central figure in this transaction, the only person who can decide who to sell papermaking to is Zhang Yang.

And this man with absolute power is busy in his own greenhouse.

Li Yue helped plant the radish seedlings, and the husband each planted the next vegetable seedling, and watered it with a kettle.

Zhang Yang's craftsmanship has always been very good, this kettle is made chic, the kettle has a long spout, and a clay bowl is installed at the water outlet of the spout.

The husband sewed the clay bowl and made some small holes, and the water poured out was a slender stream, which was very beautiful.

Holding this kettle to water vegetable seedlings is also a pleasant thing.

Finally changed the original flower seedling field to a vegetable seedling field, Zhang Yang stood up and wiped the sweat on his forehead, "There are fresh vegetables to eat in winter." ”

Hearing this, Li Yue looked up at Tianri, "This winter is late, so you can have a lot of varieties." ”

The couple stood in the huge greenhouse, looking at the lush vegetable seedlings in front of them, very satisfied.

"Sister Huang! Brother-in-law! Oh no. Li Zhi hurriedly came, "Xiao Qingqing is going to burn all the drawings in his brother-in-law's study." ”

"What?" Li Yue left quickly when he heard this.

The couple came to their study, and their daughter's pair of small sheets were sorting out the papers.

Seeing that her father and mother were coming, she grinned and said, "Mother, my daughter wants to roast duck to eat." ”

Li Yue stretched out his hand to pick her up, "Eat ducks every day, and you will become ducks." ”

The daughter looked at her little chubby hands, because she touched the ink on the paper, it was a little dirty, "When my mother was a child, I had delicious food with my father every day, and my daughter wanted to eat too." ”

"Let Auntie do it for you." Li Yue hugged her, and reached out and pinched her fat face, "Continue to learn to hold a pen and write today, and you will not be allowed to enter your father's study in the future." ”

She looked at the study reluctantly, "So much paper can be used to make a fire." ”

Li Yue said again: "There is no shortage of paper at home, and you can't move the paper in the study." ”

Washing her daughter's hands, her expression became a little more stern, Xiao Qingqing drooped her face, and had to continue writing resignedly.

Zhang Yang walked into his study, opened the drawer on his desk, and took out some small parts.

The firing mechanism of the flintlock pistol has not yet been completed, and there are many small parts that need to be polished, and this delicate work can only be done by yourself.

After assembling the previous parts, Zhang Yang pulled a pull ring above the device, and when he pulled the pull ring, he would also press the internal spring, and then pull the trigger and loosen the buckle of the spring, and the upper striking iron would hit down because of the force of the spring.

There was only a crisp sound, and the flints collided together, knocking out some sparks.

At present, the frame of the flintlock pistol is basically completed, and the next step is to adjust the ratio of gunpowder.

Because the amount of explosive force generated in the barrel determines the range and accuracy.

It seems that we will continue to experiment and adjust the ratio.

The inside of the barrel must also be kept tightly sealed, and it must be able to withstand the force of the explosion, otherwise it will explode.

There are many technical difficulties, and it can be nerve-wracking just from the idea to the drawing.

Re-putting the parts in the drawer was able to determine the two previous conditions, which involved two foundations, one was the specific ratio of gunpowder, and the other was the construction of the barrel.

It's all the foundation of the foundation, Zhang Yang scolded his mother: "your saint, you are the biggest obstacle to the development of the technical foundation, you are all harmed by you, and Lao Tzu has to build it from scratch." ”

The sages and sages are all harmful, and the one who also has this consensus is Li Tai who is in Lishan.

Now Li Tai is still racking his brains for the trachea of the pressure cooker, and the calcined copper pipes have to bend them, because the copper pipes that have just been baked still carry the temperature, which is the best time to plastic the copper pipes.

Young people's preferences may be cars and engines, but for Zhang Yang, it is a different matter, since he was a child, he has experienced the hardware skills of his parents.

I still remember that my father used the remnants of iron and parts to build a small steam engine locomotive for himself.

The locomotive was small enough to fit on a table.

It was the first toy my father had made for me since I was sensible, and it was a locomotive with real wheels that could move.

This is all the influence given by my father, and when I was a child, I liked to watch the little locomotive run when I had nothing to do.

I also developed an obsession with the more primitive power, like an old train, a tractor, or a steam turbine.

Sometimes think about it, the reason why many men like machinery and equipment in middle age is like the father of the family who retires, he will also leave his own small workshop and make some things on weekdays.

His familiarity and mastery of metals cannot be surpassed even by his current self, because in his previous life, he grew up with a major that could change the lives of poverty.

I rarely go to my father's workshop, recalling that time, it is a pity that there is no son to inherit his father's business, and my father has always regretted that he will talk if he drinks too much.

So much so that now he has to pick up the original craftsmanship from scratch, Zhang Yang feels extremely difficult.

Machinery can bring a sense of strength to men, and hands-on ability to bring a sense of achievement, after the father retired, idle in his own workshop, a busy day is a day.

The workshop is the romance of men.

This is the memory of Zhang Yang's last life.

At this moment, Li Tai finally broke a few copper pipes, and there were still a few flattening places in the bends, ignoring these details, he first connected them into the pressure cooker.

After a while, many places in the copper pipe began to leak, and Li Tai was so angry that he stomped his feet, "Why is this like this!" ! ”

Angry, Li Tai walked to Lishan, but saw his brother-in-law sitting on the mountainside, looking at the blacksmith's workshop.

"Brother-in-law, that copper pipe always leaks."

Zhang Yang took out a copper coin, "I found a problem that has been neglected all along. ”

Using his wide sleeves to sweep away the dust on the stone steps, Li Tai said in annoyance: "What's the problem?" ”

Zhang Yang observed the copper coin in his hand and whispered: "Whether it is the five baht of Kaihuang or the current Tongbao copper coin, when they mint copper coins, in order to better shape, they often add some other things. ”

"As for what has been added, it is not clear yet, and we don't need to care about this when we also mint coins in Lishan."

Li Tai's expression was solemn, "What does my brother-in-law mean that these copper coins are impure in the first place?" ”

Zhang Yang nodded, "The gas leakage problem that has not been solved for a long time is because there are other components in the copper coin, the melting point of the metal is different, and the impurities in it have not been removed. ”

Hearing this, Li Tai looked entangled again, "How to remove this impurity." ”

Zhang Yang put away his copper coin, "Copper is a softer metal, and it is difficult to remove impurities from this metal because they are die-cast together, which is why there are so many small invisible holes in the copper pipes that have been formed." ”

"When burning with a stove, you should always pay attention to the changes in the copper coin, to see if you can precipitate the impurities in it, the temperature is too high or too low, you can try to mix it with pulverized coal, if you can, go to your father to ask for some refined copper."

Li Taiyi wrote down his brother-in-law's instructions one by one, and after a year of specialized research, His Royal Highness the King of Wei can be a competent blacksmith, and his understanding of ironware is no less than that of ordinary blacksmiths.

Master Jiang stood outside the blacksmith's workshop, seeing that the thing that His Royal Highness King Wei wanted to cast had failed again, and shook his head in discouragement.

"Master, isn't that Zhang Yang?" A blacksmith pointed to the mountainside.

Master Jiang looked at the mountainside of Lishan Mountain in the distance, His Royal Highness King Wei was talking to a man in a low voice, and when he looked closely, it was indeed him.

He was instructed to leave King Wei at the beginning.

Master Jiang wiped the sweat from his forehead and continued to be busy, the last time it was Liuli, and after creating this strange thing this time, he must let him leave King Wei.

The two were still chatting on the mountainside, and the guards came quickly, "His Royal Highness King Wei, that Pei Xuanji is here again." ”

Li Tai was not interested, and directly shook his hand and said, "No." ”

"He said he was here to negotiate with His Royal Highness the King of Wei about the price of the fixed money."

Only then did Li Tai stand up, "You might as well go and meet." ”

"I'm tired of His Royal Highness the King of Wei."

Hearing his brother-in-law say this, Li Tai shook his head and sighed, "It's okay, just don't let this king continue to do bad things in the future." ”

A cold autumn wind blew, Zhang Yang tightened his clothes, and walked all the way to the mountain, it seemed that it was about to enter winter.

Another day passed, Li Tai and Pei Xuanji chatted happily, and the other party promised to pay 300,000 yuan to pay for the papermaking subscription.

This money will not be available until the beginning of the next year, after all, it is such a huge amount, not to mention that it will take some time to be transported.

After a frost falls, the wind in the Central Plains gets colder and colder, and some frost falls in the greenhouse, but this does not prevent the hot springs from providing underfloor heating for the vegetable seedlings to thrive.

This time the greenhouse was built very successfully, leaving from here, Zhang Yang walked into the library pavilion, and as soon as he walked into the library pavilion, he was greeted by huge bookshelves.

There are still many bookshelves that are empty, but it won't be long before the shelves are full of books.

Zhang Yang walked up to the second floor of the library pavilion, Li Yue was on the second floor here, where three large wooden boards were hung, and dense formulas were written on the wooden boards.
