Even if Zhao Yin has a large amount of information in his hands, he is willing to share these valuable information.

But with the current Datang, it is impossible to make all the amazing machines in later generations.

However, he firmly believes that he will plant a seed in Datang, as long as he continues to take root and sprout, and continue to thrive, one day, Datang will become a towering tree.

Electricity is a good thing to solve, and through many mediums, he can produce electricity.

But to get the most out of that power, it would take too much equipment.

Even if it is a refrigerator requested by Princess Changle, even if the drawings are given to those craftsmen, with the current technology, it will not be able to produce it at all.

A single part of a refrigerator, an air compressor, is not something that these craftsmen can solve.

In order to solve these problems, he must study the theoretical knowledge, and if he does not succeed in convincing the craftsmen, then the craftsmen will not approve of these things at all.

Even if he had already researched so many things against the sky, it would not work.

There is no way, people in this period are too conservative in their thinking, and they have no innovative thinking at all.

As the old saying goes, "Learn mathematics, physics and chemistry well, and you will not be afraid to go all over the world." ”

Although Zhao Yin is not a high-achieving student, and he doesn't know a lot of things, but he is carrying this plug-in on his body, which is absolutely unmatched in Datang, and he can also pretend to be forced here.

He has already sketched out a beautiful blueprint for Datang, and as for when it will be realized, only God will know.

"That's a good proposal for Tyre! Once the research of electricity is successful, our Datang will be better than before. ”

Li Er muttered to himself, as the emperor of a country, his eyes will look far, far away, and he must not focus on the immediate interests, because that is the work of mediocrity.

"It seems that the physical problem is going to be deepened."

Zhao Yin kept pondering, and the mechanics of the past were not involved in electricity at all, so he could only open new topics.

At the beginning, the textbooks he compiled were all used for relatively high practicality, but now that I think about it, the original decision was too arbitrary, and I blame myself for being too lazy.

Li Er has been familiar with sages since he was a child, and it can be said that he is well-read, such a person is definitely a rare existence in the entire Tang Dynasty.

is such a person who thinks he is full of wealth, after seeing modern knowledge such as unreasonableness, chemistry, mathematics, etc., he is also confused, he is simply a layman, and he doesn't know where to start.

"Why haven't you come to see your mother for so long, what have you been busy with lately?"

The eldest grandson Wujian was very helpless to pull his daughter over, this is all married, how can he still act casually like a child, what kind of system is this.

"Playing chess, reading, writing and other things, there is nothing to do all day, if it weren't for the fourth brother's business, maybe we would have gone out to play."

Speaking of this, Princess Changle couldn't help pouting, going out to play was the happiest thing for her.

Living in the palace since she was a child, she is full of too much curiosity about the outside world, and every time she goes out, she will have a lot of fun.

"Out playing?"

The eldest grandson's face was a little ugly, as a princess and a daughter, it was really ...... to show up outside

"Uh-huh! Mother, you don't know, it's really fun to go out and play! ”

Speaking of this, Princess Changle's eyes couldn't help but light up with excitement, and she almost jumped up directly.

"That is, Yin'er is used to you!"

The eldest grandson glared at his daughter, and then said helplessly.

"Changle's temperament is simple, and it's normal to love to play!"

Zhao Yin hurriedly opened his mouth to explain that in his eyes, there was no such concept that a woman would not go out of the door and would not step out of the second door, so he didn't mind taking Changle out to play.

"Hey! I don't know how long I haven't been out for a walk, a few years ago I had the opportunity to go out and walk around, but now it's good, those old people don't agree to go out for fear of hurting me. ”

When Li Er mentioned this, he couldn't help but feel bored for a while, and even looked at Zhao Yin's gaze with some resentment.

It seems that after this kid arrived in Chang'an, his chances to go out became less and less, saying that this kid was the culprit, and it didn't seem to be a big problem.

"Father-in-law, why don't we go hunting?"

Zhao Yin also knew that Li Er's current prestige was at its peak, and even those old brothers in the past would feel a little unnatural when they saw him, let alone others.

"If you do too much work, you will feel bored!"

Hunting is the only thing Li Er can do for fun now, and Datang has always maintained a martial spirit, so he didn't leave this behind.

Even if it is such a unique project, he has been impeached by those imperial historians, because he did this, not to mention the cost of the people and money, for the entire court, there is no benefit at all.

Later, because of Zhao Yin's appearance, a large number of hot weapons were placed in front of him, and he found that the martial spirit was useless in front of these iron bumps.

If you hunt with a hot weapon, it's a hand-to-hand thing, and it doesn't make any sense at all, which can't help but make him bored.

"That's right, there are too few entertainment projects in Datang."

Zhao Yin nodded approvingly, in this backward society, after dark, there is no entertainment at all, and the only pastime is to go to the Qinglou.

"Do you have any ideas, boy? Can you have some fun? ”

Hearing Zhao Yin's murmur, Li Er's eyes couldn't help but fall on Zhao Yin's body.

He is in the palace, and he is almost idle, and if he doesn't have a good time, he is afraid that he will go crazy.

"Let my son-in-law think about it!"

Zhao Yin did not refuse, and the people should indeed add some entertainment items to enrich the spiritual civilization of the people.

"It's okay to have fun, but you must not delay the business, especially the electricity thing, it's really reassuring for Tai'er to study it, Yin'er, you have to pay attention to it at all times."

The eldest grandson Wujian was originally quite moved by the content of the conversation between the two, but he never expected that when the two were talking, the content between the words would change taste.

"The queen can rest assured, I still know Tai'er, since Yin'er has provided him with a method of friction and electricity, presumably he will immerse his mind on this in the near future, and there will be no chaos."

Li Er said very confidently that his son himself knew that with this kid's character, he would never have the courage to try something too dangerous.

It's like Yin'er's whimsical idea at the beginning, using iron chains to not catch thunder and lightning, such a whimsy, Li Tai would never have imagined, even if he thought of it, he would not be as bold as Zhao Yin.

Zhao Yin did not open his mouth to persuade, but nodded very approvingly, worthy of being a father, and his understanding of his son must definitely surpass others.

As for the friction and electricity generation, he deliberately made it up, Li Tai, this kid is good at everything, but he likes to specialize in the horns too much, and everything must be studied thoroughly.

So he can only give this kid an introduction first, and as for when he can study the principle in it, it will have to wait until later.

After chatting casually for a while, Zhao Yin and Princess Changle got up and left.
