"I'm afraid that speed will be difficult to achieve!"

The eldest grandson, the emperor, was not as optimistic as Li Er.

Now that we haven't even studied a single spark, how can we apply it to trains?

"The queen mother is right, if you want to reach more than a thousand miles per hour, you really have to wait for one or two hundred years!"

Zhao Yin pinched his smooth chin and said lightly.

High-speed rail is not a train, it can run with a railroad track, with Datang's current foundation, even if he has the help of the system, he can't build a high-speed rail!

"It's a pity that I won't see this day!"

"Is there any other use for electricity besides trains?"

Princess Changle also came to be interested.

"Of course, with electricity, electric lights can be made, and with electric lights can turn night into day!"

"That's great!"

Princess Changle slapped happily.

"You can also cook rice instead of a stove!"

Later generations of rice cookers were very useful.

"Anything else?"

Princess Changle didn't seem to have heard of it yet, and tilted her head and asked.

"It can also be used for cooling, and it's still cool indoors in the summer!"

The role of air conditioning is also great.

"This is good, this is good!"

Little stars appeared in Princess Changle's eyes.

"It can also be used to keep food fresh and slow down the spoilage of fruits and vegetables!"

Zhao Yin talked eloquently that in later generations, refrigerators are household appliances and indispensable things in people's daily life.

"Really?"

Princess Changle looked at Zhao Yin with suspicion, such a thing could not exist at all.

But thinking about this kid's past style, his words will definitely not be groundless, thinking of this, he suddenly looked at Zhao Yin's gaze even softer.

"After talking for a long time, I just think that the train is a little useful, and I don't want anything else!"

At this time, Li Er was completely like he was forcibly lifting his spirits, if it weren't for this kid talking here and changing to another person, Li Er would let him get out of here.

"Father-in-law, if you think so, then you are very wrong, although these things are daily necessities, but if electricity is placed in the military, it will definitely not be ambiguous."

Zhao Yin was also very helpless, obviously, Li Er didn't take the things he just said to heart.

Of course, this can't be blamed on this old boy, who has never realized the importance of these things without seeing them with his own eyes.

"Oh? And this matter, so you kid are telling me about it? ”

Hearing that it could also be used in the military, Li Er immediately became interested, and the tastelessness just now suddenly disappeared, with an excited look.

"Electricity" is a new term, something that used to be only seen in thunderstorms, and now this kid actually says that this thing can still be used by me.

Although this kid had successfully captured a lightning bolt before, and after being shocked, he had no other thoughts, but he never thought that after such a long time, this kid would put his mind on this.

Before he came to Datang, Datang's living conditions were extremely backward, and they could even reach that kind, communication basically relied on roaring, going out basically by walking, heating basically by cuddles, security basically by dogs, and sex life basically by hands......

"Ahem! Judging from the current situation, the soldiers still use horses to convey news in the army, and the speed is just a flying pigeon. ”

Speaking of this, Zhao Yin couldn't help but slow down his tone, and after his eyes fell on Li Er, who nodded from time to time, he spoke again: "If you switch to electricity, you can reach it instantly!" ”

For fear that Li Er wouldn't understand the terms of later generations, such as telephones, mobile phones, telegrams, etc., he could only explain them simply.

"Is that true?"

Li Er stood up directly on the dragon chair, if he could really reach this speed, then what eight hundred miles of urgency and other things would no longer be on the table, and he would also be able to control everything in the frontier at the first time, which undoubtedly made him very tempted.

As the emperor, every time the army goes out, his heart is always in the air, because these soldiers, once they leave Chang'an, then they are no longer under his control, and he has no way to know the daily information of these soldiers.

Passing the book through Fei Ge and passing it on as fast as possible was too time-consuming, and even sometimes, they didn't even have time to send supplies.

If he can say that to this kid, then what else is he worried about?

Anything he encounters on the march, he can know at the first time!

Moreover, he can also check whether these soldiers have different intentions in time, and only in this way can he sit back and relax.

"These are just the tip of the iceberg of electricity, if you use electricity in industry, father-in-law, you will find that now relying on manpower, Datang's development will be so slow."

After this attack, Zhao Yin's expression was very confident, and he almost patted his chest and told Li Er that what he said was already in his pocket.

"Since electricity is a thing that benefits the country and the people, then I, Datang, will definitely develop it, and you are responsible for this matter, I am waiting for your news."

Zhao Yin's words made Li Er quite moved, so he stopped being verbose at the moment and directly implemented this matter.

Since this matter was brought up by this kid, then this kid is the best person in charge, as for whether he will pick on the kid in the future, that's the kid's problem.

He won't care, he won't monitor, all he wants is a result, a result that satisfies him.

I didn't expect that the things made by this unconscious son would be of such a great use.

"Father-in-law, I don't take you to play like this, this thing seems to be very simple, if you want to make full use of electricity, you need to study a series of machines, otherwise, it is impossible to use it without a carrier......"

The corners of Zhao Yin's mouth kept twitching, if you let yourself be responsible for such a thing, you must not exhaust yourself to death.

Even if he relies on the power in his hands to mobilize the elite to jointly research equipment, it is good to be able to understand his painstaking efforts, but if he doesn't understand, he must not be regarded as a fool, an ordinary man, and he actually talks about studying Tianlei, which is no different from looking for death.

"Didn't I give you a deadline? Take your time, I'm optimistic about you. ”

Seeing Zhao Yin's reluctant expression, Li Er couldn't help laughing, and after waving his hand to him slightly, he said that he didn't force him, all of this was proposed by your kid himself, if you can't get a score for me, you kid is bullying the king.

"Husband, can you develop that refrigeration machine first?"

Princess Changle, who had been listening to the conversation on the side, hurriedly ran over, directly reached out and hugged Zhao Yin's arm, shaking constantly, pouting her little mouth, and being extremely cute.

"Yes."

In response to Princess Changle, there was a big smiling face, and he pinched her pretty face very dotingly.
