The matter of circumnavigating the world is settled, and all that remains is to wait, but Li Tai suddenly thought of the matter of friction and electricity, and couldn't help but feel a little depressed.

He took the silk and glass rods back and studied them for a long time, and experimented with other substances, but no good progress was made.

"I wonder how this electricity can be produced?"

Li Tai asked suspiciously.

This matter has bothered him for many days, and today he finally has a chance to catch this kid, so he must ask to understand!

"Friction can only produce some small load of electricity, if you want more electricity, you can use wind, hydropower, thermal power to generate electricity, power generation is not very difficult, the difficulty is how to stabilize the voltage and store electricity!"

Zhao Yin briefly explained to him, so as not to make it difficult for this kid to sleep.

If he just held a glass rod and a piece of silk, he would never have been able to study electricity!

"So how do you solve the problems you mentioned?"

However, after listening to Zhao Yin's words, the curious Li Tai not only did not mean to leave, but stared at him with great interest.

"This matter will not be clear for a while, and I will compile it into a book in the future, and then show it to you!"

Zhao Yin didn't want to continue this topic here, otherwise this kid would be finished.

"It's ......!"

Li Tai understood that he was giving an eviction order, but he was still unwilling, "Then you have to hurry!" ”

After sending Li Tai away, Zhao Yin hurriedly ran to find the three beautiful wives and concubines in the inner house!

"When did you come back, husband?"

Hou Qingli happily ran to Zhao Yin's side.

"Are the ships of the Navy already out to sea?"

Princess Changle and eldest grandson Yujia, who were playing, also put down their rackets and walked towards him.

The navy going to sea is a big deal for Datang, but they are just a class of women, and they just want to live their own small life, and they don't want to care so much!

The reason why I asked this is because Zhao Yin promised them that after he was busy with the affairs of the navy, he would take them out to play!

The last time I went out was too short, and I hurried back to Chang'an City before I could enjoy the scenery outside!

"I'm gone, but I still have some things to tidy up, so I'll take you out to play in a few days!"

In his previous life, Zhao Yin liked to travel in the mountains and rivers, but because he was just a dick, he had no money to travel, so he had to give up.

Now that he has crossed over, and there is still a beautiful wife and concubine beside him, he must go more to make up for the regrets left in his previous life!

"Are we still going to Luoyang?"

The eldest grandson Yujia tilted his little head and asked with a wink.

Luoyang is the ancestral home of the eldest grandson Yujia, but last time he was in a hurry and didn't have time to worship his ancestors, and because of this, he was counted down by his father!

If she goes again this time, she will definitely have to take Zhao Yin to worship her ancestors together!

"Luoyang has already been there last time, this time there is a rare opportunity, why don't we go to Jiangnan?"

Hou Qingli shook her head and didn't want to go to Luoyang again.

After an ancient woman got married, three obedience and four virtues were the most basic, and it was impossible to travel at will, so she didn't want to waste this opportunity on Luoyang.

Besides, even if Zhao Yin allowed them to play around, he was too busy to accompany them, so what was the point?

"Jiangnan is good, they all say that Jiangnan is picturesque, should we go to Jiangnan?"

This proposal resonated with Princess Changle.

In the past, when she was in the palace, she often heard her father mention Jiangnan, saying that he must go to Jiangnan if he had the opportunity, but his father was too busy and never had time to spare.

If she goes to Jiangnan this time, she can also go back to the palace to tell her father about the beautiful scenery of Jiangnan!

"Okay, two to one, Jiangnan wins, let's go to Jiangnan this time!"

Zhao Yin immediately made a decision.

"It's good!"

The eldest grandson, Yujia, also nodded.

She just asked casually, if there was a better place, she wanted to go too!

"Great, we're going to Gangnam!"

Princess Changle had already jumped up happily at this time.

They have only imagined the scenery of Jiangnan through poetry, and they never thought that one day they would really be able to go over to see it, and they were extremely excited at the moment!

In the Tang Dynasty, where the transportation is extremely inconvenient, traveling far away is something that the people almost will not do, but after the train opened, many nobles in the DPRK and China went to Luoyang to have a round.

It is said that he is inspecting the train, but in fact, it is for his own curiosity.

But Li Er, who has been working hard, didn't be able to go over to take a look once, for fear of being caught by those old guys in the Yushitai!

After learning the news that they were going to travel to Jiangnan in a few days, the girls immediately began to pack their bags, for fear that they would not bring enough things!

Zhao Yin, on the other hand, concentrated on collecting knowledge about electricity on the universal search, and recorded them and handed them over to Li Tai.

"Pony, since you have such a good idea, why don't you hurry up and implement it?"

Because of the excitement, one of Li Tai's faces was already slightly distorted, and he wanted to rush over and knock him down immediately.

"These are all theoretical, and whether they can succeed or not will only be known after your experiments!"

Zhao Yin looked at the goods in front of him with some vigilance, because of the problem of knowledge, he wouldn't even change his orientation, right?

"Don't you care about the colt? Something like this kind of precedent must not be without you! ”

Li Tai had already seen that Zhao Yin wanted to be the shopkeeper, so he began to persuade immediately.

"Datang is full of talents, where is it so serious as you say? Besides, the horse has promised the princess that she wants to take them to Jiangnan for a visit, if you have leisure, you might as well go together? ”

Zhao Yin directly shook his head like a rattle, and did not directly choose to refuse, but chose a reason that no one could refute.

"Since ancient times, heroes have been sad to pass the beauty pass, and the foolish brother really can't bear you to fall like this!"

Li Tai hated iron and looked at Zhao Yin, obviously full of economy and talent, but he liked to soak in the pile of women.

is obviously a great talent, but he is unwilling to contribute to the country!

"Ahem......! That's not what the words say! ”

After Zhao Yin coughed lightly twice, he kept glaring at him.

"What? Isn't what this king said right? A colt really shouldn't give up the opportunity to play for the country for the sake of a few women! ”

Li Tai was a little unhappy.

This is for his own good, why is this kid so unenlightened at this time?

"Fourth brother, I don't know what you think?"

At this moment, Princess Changle's somewhat angry voice came.

"Huh? Why are you ...... here? ”

Hearing this voice, Li Tai was startled, and when he turned his head, he saw Princess Changle's eyes that wanted to kill.

"That...... That one...... The fourth brother suddenly remembered that he still had important things in his hands, so he took his leave first. ”

Li Tai hurriedly immersed himself, raised his right hand and patted his forehead, and after finding a reason to be awkward, he flashed directly.

"Humph! I didn't expect the fourth brother to be so bad, he actually let my husband stay away from our sisters, and my husband will stay away from him in the future! ”

Looking at Li Tai's back, Princess Changle's face was very ugly.

"I think King Yue's proposal is good, but I don't know if my husband can endure loneliness, so that our sisters can live in peace for a while."

The eldest grandson Yujia covered his mouth and chuckled, turned his head to look at Zhao Yin on the side, and couldn't help but tease.

"Hmph, it's just that I want to be a monk, but I still want to call my husband, I'm really angry!"

Princess Changle crossed her hands on her hips and looked out of the door angrily.

Although I know that such a thing cannot happen at all, as a woman, hearing someone say bad things about them with my own ears, even if it is a loved one, I am afraid that it will not feel good in the bottom of my heart.
