Tang Dynasty: Beyond Time and Space, My Best Friend, Princess Jinyang!

It's all in hand, and Li Lizhi will seem hypocritical if she refuses.

"Thank you, young man!" Li Lizhi thought silently in her heart, and she had to add two more boxes!

"Sister~ look at the duck~"

The little princess was more anxious than Li Lizhi.

"Okay!"

Li Lizhi was also looking forward to what gift Xiao Ran would give.

Carefully opened the gift box, and saw the neatly arranged wind-breaking duck inside, which was still different.

Li Lizhi smiled when she saw the wind-breaking duck. Li Lizhi didn't expect Xiao Ran to give this.

Li Lizhi liked the wind-breaking duck but didn't say it, but Xiao Ran found out.

This is the most rare thing. Saying that you will give it and not saying that you will give it are two different things.

Li Lizhi was happy in her heart, and her thoughts were discovered.

"Wow~ so many little ducks~"

The little princess picked up one and looked at her helmet not far away.

Suddenly felt that her helmet was not so good.

It's different that I only have one, and my sister has a box.

"So many!" Li Lizhi looked at Xiao Ran, not knowing what to say for a moment.

"I didn't know what kind my wife liked, so I bought a few different ones."

"I like them all, they are all very cute!" Li Lizhi was telling the truth.

"Sister~" The little princess pulled Li Lizhi's arm, "Can you give me a duck~"

"Okay, okay, Sizi, pick one!"

With Li Lizhi's permission, the little princess picked a wind-breaking duck with a chain and happily took it aside to play.

Li Lizhi looked at the thermos next to her.

"My dear, what is this?"

"This is called a thermos. Pour the boiled water into it to keep it warm, so that my wife and Sizi can drink hot water conveniently."

Li Lizhi pointed to the thermos, "How long can it keep warm?"

"Pour it in tonight, and it will definitely be hot tomorrow morning."

Li Lizhi also felt that it was much more convenient to drink hot water this way. It was okay to drink cold water in summer and autumn, but it was a bit uncomfortable to drink cold water in winter. It was better to drink hot water.

"What a good thing! Is this thermos pot expensive?"

Li Lizhi thought that if it was cheap, she would prepare one for Empress Changsun and others.

"This one is not expensive. You can buy it for a few dozen yuan."

Li Lizhi was delighted. The price was much lower than expected.

If it was convenient to buy, Li Lizhi thought she could prepare a few more.

"It is indeed not expensive! I saw a copper thermos pot in a book before. It also has a heat preservation effect, but it is much worse. It can't be compared with the thermos pot of the young master."

"Copper thermos pot? What era is this thing?"

Li Lizhi smiled and said, "This is an artifact that existed from the Warring States Period to the Han Dynasty. It has the characteristics of a thin neck, a large belly, a round bottom, and a small mouth."

"Some of these copper thermos pots also have the characteristics of a long neck, a tilted head, or a bird-shaped head decoration."

Xiao Ran shook his head, "I haven't heard of it."

Things similar to thermos pots appeared more and more after the Song Dynasty, and the heat preservation effect became better and better.

Before the Song Dynasty, the heat preservation effect of this kind of thing was a bit touching.

In the Song Dynasty, a two-inch thick air layer was used to keep warm, and the knowledge of heat transfer and the conditions and methods of heat preservation were correctly understood.

In the Yuan Dynasty, a double-layer container made of copper appeared, with hot water in the interlayer, which was used to keep the teapot warm.

This design uses the principle of water vapor to maintain the water temperature.

In the Qing Dynasty, the thermos bottle evolved into a teapot barrel made of wood. The principle is to stuff cotton or goose feathers with heat preservation effect between the teapot and the tea barrel to keep the temperature of the tea.

Simple thermos can also be made in the Tang Dynasty, but the effect is not satisfactory.

Xiao Ran, a modern man, must not look down on it.

"Little Langjun, I have to trouble you. I need a few such thermos." Li Lizhi pointed.

"Yes, it's not difficult. My lady, this is a fragile item. You have to be careful with it, otherwise it will break easily."

Li Lizhi pointed at the thermos, "It looks very sturdy, right?"

"It keeps warm because the inner liner is special. The inner liner is not sturdy and it will break easily with a slight collision, so you have to be careful."

"Okay, I remember!"

The little princess walked over with the wind-breaking duck and rubbed her eyes.

Xiao Ran knew that the little princess was sleepy and it was time to go to bed.

"Little sac~ I'm sleepy~" The little princess didn't look for Li Lizhi, but threw herself into Xiao Ran's arms.

Li Lizhi was a little surprised.

At this time, the little princess was instinctive and didn't think much.

"Okay, go to bed!" Xiao Ran picked up the little princess.

"Qinglan and Yushu should be back soon. Prepare some hot water to wash up before going to bed." Li Lizhi stretched out her hand, "Give it to me, young man!"

"Okay!" Xiao Ran handed the little princess to Li Lizhi, "My lady, it's getting late. I'll go back first!"

"Okay!"

Li Lizhi carried the little princess out of the inner hall.

Li LiZhi didn't say too many polite words, because being polite is just being distant and distant.

Xiao Ran didn't leave in a hurry, but prepared the medicine that Li Lizhi was going to take and put it on the table.

He ran to the dressing table, reached out to take out the A4 paper and a marker, and wrote on the paper: Wife, remember to take medicine before going to bed!

Xiao Ran also drew a cute Q-version smiley face.

He habitually folded the A4 paper into a paper airplane.

Then he left the inner hall.

Li Lizhi took the little princess to wash up, and then returned to the inner hall.

The little princess fell asleep in Li Lizhi's arms.

Put the little princess on the bed and cover her with the quilt.

Qinglan brought two hot water bottles over, "Your Highness!"

Li Lizhi took the hot water bottles, one for the little princess and one for herself.

"Clean up the table!" Li Lizhi pointed.

Qinglan walked over and saw the paper airplane folded from A4 paper, and knew that it was Xiao Ran for Li Lizhi.

"Your Highness, this is what the young master left behind."

Seeing the paper airplane, Li Lizhi was also full of joy, "Give it here!"

Take the paper airplane and open it, and see the words on it, Li Lizhi's heart is warm.

This feeling is good, it's hard to explain, but Li Lizhi likes it very much.

Looking at the table, Xiao Ran has prepared the medicine.

"Yushu, pour hot water!"

"Qinglan, this is a thermos, boil water and pour it in, it keeps warm, just pour it when you want to drink hot water."

"Yes, Your Highness!" Qinglan took the thermos.

"Be careful with this, don't bump it, it's easy to break." Li Lizhi didn't forget to remind him.

This made Qinglan nervous all of a sudden, for fear of breaking it.

The things Xiao Ran brought can't be bought in the Tang Dynasty.

It can be said to be priceless. If Xiao Ran doesn't give it to you, you can't buy it no matter how much money you have.

"Yes, Your Highness, I'll remember that!"

Taking the hot water brought by Yu Shu, Li Lizhi swallowed all the medicine.

Perhaps it was a psychological effect, making Li Lizhi feel much better after taking the medicine given by Xiao Ran.

"You guys go down and rest too!" Li Lizhi also had to sleep, she was still not feeling well now, and wanted to lie down early.

"Yes, Your Highness! I'll change your clothes for you!"

"I can do it myself, you guys go down!" Li Lizhi walked to the bed and sat down, the little princess was sleeping soundly.

The dog was lying next to the bed, and the cat was also on the bed guarding the little princess.

Li Lizhi was about to change her clothes, and saw a paper plane flying over the screen and landing on the ground in front of her.

Li Lizhi didn't expect there was a paper plane, so she quickly picked it up and opened it.

'Good night, my lady! See you tomorrow morning! '

Xiao Ran mainly told Li Lizhi that he would come in the morning, so as not to scare Li Lizhi too abruptly.

Saying good night was just a matter of convenience.

Li Lizhi raised her lips slightly and held the A4 paper in her arms.

She was very happy.

Li Lizhi got up and found a pen and ink.

She wrote on the paper: Little Langjun, good dreams, see you tomorrow morning!

After writing, Li Lizhi folded it into a paper airplane and put it on the dressing table.

It felt inappropriate to put it in other places, so it was better to put it here.

The best way was to give it to the little princess, but the little princess had fallen asleep, and she couldn't wake her up.

Li Lizhi put down the paper airplane, and then she was satisfied and went back to the screen to change clothes and go to bed.

Holding the hot water bottle, she gently hugged the little princess.

What she was thinking about was Xiao Ran.

Xiao Ran also reached out to the dressing table, picked up the paper airplane and opened it.

Seeing the content inside, Xiao Ran wanted to reply to Li Lizhi again.

But considering that Li Lizhi had fallen asleep and it was troublesome to get up, Xiao Ran didn't throw the paper airplane again.

Take out the rosewood box you got for the first time, open it, and put the paper airplane in.

Li Lizhi was not the only one who kept the paper airplanes. Xiao Ran also kept all of them.

Xiao Ran put all the notes and letters with Li Lizhi's handwriting in the rosewood box.

Rosewood is expensive, but these letters are also of great significance!

Xiao Ran felt that it was just right to put them in there.

After putting the box away, Xiao Ran also prepared to go to bed.

This time is indeed early for people in the 21st century, but in order to get up early tomorrow, he still wants to lie down early.

Just lying down is not enough. It's too exciting. I toss and turn and can't fall asleep.

It's not just Xiao Ran who can't fall asleep. Li Lizhi is also the same.
