"Then... Miss Jing'er, there is something happening recently. It requires a lot of manpower and money. I wonder if the girl is interested." Zhang Xuan had already realized that he was not concerned about calling a girl Jing'er's intimate nickname, but his father was standing there.

Jing'er, with the word "girl", seems less ambiguous.

"You said." It's not a waterwheel, not the paper he said, there's anything else?

"Some day ago... I found something interesting..." Zhang Xuan began to hesitate again. Iron, a powerful weapon of the country, is also an important strategic material for the country even if it is placed in his previous life. In the history of his previous life, most of the time, salt and iron were controlled by the state.

Let’s not talk about it, iron must be made, iron pot, iron spoon, hoe, sickle...

If you want a smooth life, you must not have any iron. Look at the situation in Lan County, let alone the son of the county magistrate, there are very few resources to call. Even if he is the county magistrate of Lan County, he cannot play with it.

There are more than 18,000 people in Lan County, and most of them need to be busy every day for a meal. Even if Zhang Xuan is full of ideas to make a fortune, facing such a weak foundation, even a small county town with no foundation at all is helpless.

Through three things: water wheel, papermaking, and copper casting, Zhang Xuan understood that the plot of time-travel novels is quite nonsense. Without a foundation, anyone who comes will be useless.

When Zhang Xuan attended a meeting in his previous life, he discussed this issue with an expert in metal machinery. How long does a modern person travel to ancient times can make a useful machine tool? It doesn’t need good ones, just the most primitive ones.

The result is very bad. In the eyes of people in the past, a simple machine tool can make people suffer a lot of trouble and collapse. It is not a good idea to understand metallurgy, so you need to start with a more basic refractory brick. Next, you will find that without relevant equipment, you cannot distinguish the carbon content with the naked eye. Whether the smelted pig iron or cooked iron can only rely on experience, let alone steel and more complex alloys.

Machine tools can’t be made by making a pile of unstable iron. Think about the tool steel used by machine tools, then it’s not something that can be played by one person.

During the days when he was recovering, Zhang Xuan had thought that he would borrow the knowledge of his previous life to change his living environment as soon as possible. If it was easy to fight for dominance in the world, or could he have fun?

Having seen Lanxian and the basics, the pace of life of people in Dazhou, and the legendary professions in his memory, he gave up directly. With that skill, it would be better to think about how to get the toilet paper out as soon as possible.

"My brother has something to say, please speak out." Seeing his hesitation, Yao Jing made it clear that she didn't like the twists and turns. Her father was exiled to five thousand miles by himself. She applauded and praised the officials in the court, but none of them spoke happily and felt upset when they looked at it.

"Yeah, I'm just thinking about how to explain it to you to understand." Zhang Xuan found a crappy excuse.

Yao Jing doesn't like to listen to these words, what does she mean that she can't understand...

I glanced at the water truck and thought about the paper that Zhang Xuan said. It seemed like this. The ray of anger that had just risen dissipated and I quietly waited for Zhang Xuan to explain.

Yao Qian was even more surprised to read. Outsiders didn't know that he was a father too clearly. He named his daughter Jing because she was very impatient after she was born and could not tolerate any delay. As she grew up and learned, there were no books she could find before. In the end, even the words, words, and words in the court were read.

When it comes to studying, he, a great scholar, dare not say that he read more than his daughter. If he read more, his knowledge will naturally be higher. Someone actually said in front of her that she didn't understand, so she could bear it?

"Does Miss Jing'er know metal?" I learned about the misunderstanding of paper last time and found that it was really necessary to explain it carefully.

"Copper, lead, zinc, tin, black vanadium, red vanadium, cave gold, sky fall, earth fall..." Jing'er looked calm and reported more than ten kinds of metals in one breath. Yao Qian had never heard of several of them.

After asking more questions, Zhang Xuan had only heard of the first four types, and the ones behind him, and I don’t know if they are the things he understands. It’s easy to say that meteorites are like black vanadium, cave gold, and are they the same as vanadium and gold that he understands?

Zhang Xuan naturally knew about the metal of vanadium. Humans only discovered it for more than two hundred years, and most of it were companion metals in metal ores. With the original smelting technology of the Great Zhou Dynasty, it was impossible to purify it. Not to mention vanadium, even gold and silver, the temperature of firewood is too low.

Of course, there are natural gold nuggets in nature that do not require smelting. It is said that the people of the Great Zhou Dynasty know that gold is understandable, and it is unlikely to refine it in large quantities.

"I discovered a new metal. I have never heard of it before. Maybe someone knows it..." Zhang Xuan said a little confusedly, and Yao Jing understood it.

"Yeah, you said." The message transmission of Dazhou was very slow. It may take a month to pass on a thousand miles of letters, or half a year, or you will never receive a letter. After all, using the Flying Horoscope of Wanli, even the third-rank scholar of the dynasty would be painful.

What's more, Wanli Feihong is just an exaggerated name, who doesn't name a nice and domineering name?

The means of flying horoscopes in the thousands of miles is not uncommon, but the materials are relatively precious. In fact, the transmission distance is 100 miles per grade. Even a first-class scholar can only teleport nine hundred miles, which is several times different from ten thousand miles.

If you don’t know the general position of the other party and communicate in advance, even if you use it, the other party will not be able to receive it. There are many tricks in this method and it is difficult to understand this mysterious method without nurturing good spirit.

"I call it iron. This word is written in this way. There are many raw materials for iron. You can smel it out with some means. During the smelting process, you can use some means to make the iron soft or hard, and study it slowly according to needs..." Zhang Xuan explained iron when no one knew what iron was, and it was really a bit difficult.

Items can be drawn directly, like water wheels. Even if they do not exist, as long as they are drawn and thinking with their brains, it is easy to draw correct conclusions. After all, the nature of wood after changing its shape and the power of river water can be imagined by anyone with a little knowledge.

Iron is just a metal element. It is really embarrassing to just say it without physical objects. Even materials experts have taught students in several fields, but have never considered explaining the basic issues of iron to students.

It’s still the basics. Even if I explain iron to a child in my previous life, I just need to take a piece of iron for him to show it. There is no physical teaching. This seems to be a major in the film school.

Yao Jing listened very seriously. Even if Zhang Xuan had some words repeatedly and repeatedly, she did not interrupt. Until Zhang Xuan said nothing, she asked, "How about Bi Tong?"

Before Zhang Xuan could speak, Yao Qian suddenly asked, "Who is your teacher?"

"Master Feng..." Almost subconsciously, Zhang Xuan blurted out the Feng monk. During this period, as long as he had the chance, he would mention the Feng Master Feng who had no impression of him in front of his father, and was also instilling himself with his subconscious mind that Master Feng was his teacher.

"Monk?"

"Well, this..." Zhang Xuan hesitated and did not deny it or admit it.

"Have you cultivated magical powers?" Yao Qian didn't give him a chance to think, and asked a question, but was not anxious. The voice seemed to have strange magic power, which made people unable to reject his questions.

"How do you know?" He blurted out subconsciously again, and Zhang Xuan burst into a cold sweat. Hell, he seemed to be unable to control his brain and mouth.

Fortunately, that Master Feng really exists. As for the so-called magical power, Zhang Xuan can understand it magically by just listening to these two words. Don’t be surprised why the word magic is used to describe it. Zhang Xuan has long discovered that it is not ordinary to explain the details to the people of the Great Zhou Dynasty. In one sentence, there may be several words that have ambiguity.

"You're sneak attacking?" The next moment, Zhang Xuan reacted, with a hint of anger, and glared at Yao Qian. The old guy must have given him some tricks just now. After all, he lived for nearly fifty years in his previous life, and Zhang Xuan's self-control ability is still quite strong.

"Don't blame me, Yao was rude." A starlight flashed in Yao Qian's eyes. Such a young monk was no worse than his daughter's talent, or even better.

"I don't know where the monk Feng is, can I send a message? Yao is willing to drink with him." A young monk who has just started is just a little color. What really makes him care about is Zhang Xuan's teacher.

At this moment, Zhang Mo and Zhang Xuan's status and status were no longer important. He had cultivated supernatural powers at the age of twenty. With such talent, even if Zhang Xuan lacked arms and legs, there were many monks who were willing to put down their figure and accept him as his disciple.

"Master Feng passed by Lan County six years ago. The boy was unlucky and only listened to the teachings for a few months." Fortunately, Master Feng left some impression on his ex-boy Zhang Xuan. Even if he couldn't remember his appearance, he would not have made any mistakes in the time he stayed in Lan County.

"Oh..." Yao Qian's eyes were dawn, and the stars were intertwined. In his black eyes, it was as if a universe was in the beginning and end.

Six years ago, just a few months...

Two keywords allow Yao Qiannao to make up for other information. Six years ago, a great monk named Mr. Feng passed by here and saw at a glance that this son was extremely talented. He had an urgent matter, but he stayed for this son for several months and left.

If there were no accidents, Mr. Feng should have had an accident, otherwise he would not have been able to go there for six years without returning.

This son, based on Mr. Feng's teaching for several months, has been deeply comprehensible. He will not be wrong after six years of cultivation of supernatural powers. He should have been like this. Yao Qian believes that Zhang Xuan's cultivation of supernatural powers should be extremely short, and it will never exceed half a year.

No matter where a true monk is placed, it takes half a year to illuminate the world. If you haven’t heard of it, it can only prove that he has recently cultivated supernatural powers. This is not difficult to calculate.

Only those who have great righteousness can become great Confucians.

Only those who have supernatural powers can become monks.
