Chapter 1118 Cold Alley Effect

Li Zheng nodded and said, "I understand, is there anything else?"

Li Junxian seemed to think for a while and said again: "It's nothing more, I'll leave first."

After Li Junxian left, Li Zheng and Li Tai stood up from the river.

The two of them put on their clothes to change and finally felt much more comfortable.

Li Tai went to the academy again.

There was nothing he could do when he went to the academy, so he would take a nap in the academy at most.

When she returned home, Li Lizhi was still busy at home.

Wu Mei and Gao Yang were in and out, and they had already traveled back and forth several times in just half an hour.

In the account room, Li Lizhi was still looking back and forth on the account books, seeing that there was already sweat between her forehead and hair.

The summer in Guanzhong is really not a joke.

Fortunately, there is a lot of ice at home.

Since the creation of saltpeter ice, there is not no cure.

Li Lizhi was busy and saw Li Zheng taking a basket of ice crystals.

Put the ice crystals in the window, Li Zheng closed the window, leaving a gap about the size of his arm.

Then, the rear windows do the same.

Li Lizhi looked at Li Zheng's every move and couldn't understand it for a moment, so she simply stopped the movements in her hand.

After finishing his work, Li Lizhi said curiously: "What are you doing?"

The account room with the window closed was a little dim.

But after lighting the oil lamp, it's fine.

After half an hour, Li Li felt a gust of cool breeze blowing from the gap. Because there was ice on the side of the windowsill, the wind brought the temperature of ice.

After another half an hour, the account room finally became cold.

Li Lizhi said curiously: "How did this be done."

Li Zheng explained: "Do you know the cold alley?"

“Cold alley?”

After thinking for a while, Li Lizhi shook her head again, and she had never heard of the title Lengxiang.

Cold alleys are products that have been found since the Song Dynasty.

At this time, the Tang Dynasty did not have a large area of ​​brick houses.

However, people just don’t know the name Leng Lane and don’t understand the reason.

Li Zheng sat down and shook his fan and said, "Some houses are very close to each other, and there is a path between the houses. Because the height of the house is not exposed to sunlight for a long time, and because of the air flow, this kind of alley is very suitable for summer vacations."

This was also when people in the village often went to the alleys to escape the summer heat when they were young.

It will be cooler there.

Li Lizhi thought and said, "I understand a little when you say that."

Li Zheng said: "I use the principle of cold alleys, because your account space is narrow, but it is also very narrow and long. Because of the ventilation in the front and back, this brings the basic conditions for cold alleys."

Li Lizhi nodded slightly.

Li Zheng continued: "I used ice again. When the wind blows, after passing through the ice, the ice will absorb heat as the ice melts, which will also cause the room to become colder."

Looking at Li Zheng's expression, Li Lizhi said: "We have known each other for so many years, and I really can't figure out where you learned so many strange knowledge."

Li Zheng smiled awkwardly and said intermittently: "I..."

"Will an old Taoist priest really pass by your doorstep and teach you this knowledge?"

Li Zheng smiled and didn't plan to answer again. He turned around and walked out of Li Lizhi's account.

Mortals cannot understand.

It is very laborious to make fans in this era.

It is difficult to achieve the effect of the fan without electricity.

Hydraulic power is definitely not good, and human power is even more thankless.

Making a generator?

The era of making motors alone is simply impossible.

Sure enough, I still have to read more.

Only scientific knowledge can bring us a better life.

Li Lizhi is no longer surprised by these strange things about Li Zheng.

I simply don't think about some things that I can't figure out.

Li Lizhi continued to focus on dealing with her account book.

Xu Hui held the watermelon and said, "Chang'an Order, this is a frozen watermelon."

Li Zheng looked at Xu Hui while eating the watermelon, and her eyes immediately dodged to the side.

Recently, she has always been dodging herself when facing herself.

Li Zheng looked at her and said, "Have you had any worries recently?"

"Things to worry?"

Xu Hui came back to her senses and looked around and said, "I haven't had much worries recently."

Li Zheng nodded suspiciously.

Seeing that Li Zheng stopped asking questions, Xu Hui sighed. In fact, the biggest grudge in her heart was that Li Zheng is now a calm man.

I didn’t think it was because when I first met Li Zheng, he was just a fourteen-year-old child.

After so many years, Li Zheng is over twenty years old.

Xu Hui is already in her twenties.

After being together for so many years, the relationship has long been no longer the same feeling as when we first met.

The relationship between master and servant is pressed on Xu Hui's heart.

I am a master-servant relationship between myself and Li Zheng. I am the maid of Chang'an Linghe Princess, so I shouldn't have any other ideas.

Xu Hui kept reminding herself in her heart.

Li Zheng spit out the watermelon seeds and said, "By the way, Your Majesty is coming to our Jingyang to escape the summer heat tomorrow. Please let the people in the village prepare."

Xu Hui said in surprise: "Will you come tomorrow?"

Li Zheng nodded, "I'm quite anxious."

Xu Hui hurriedly said, "Your Majesty's villa needs to be cleaned up early."

In the evening, Li Lizhi also learned that Li Shimin was coming to Chang'an to escape the summer heat.

At the dinner table, the whole family was having a meal.

Li Lizhi said: "This time my father came very suddenly."

Li Zheng ate millet rice and said, "Chang'an City is very hot at this time. Maybe your father couldn't stand in Jingyang to escape the heat at the beginning. He really couldn't stay in Chang'an and then came to Jingyang and didn't care about his face."

Hearing this, Little Vine almost laughed out loud while eating.

Li Lizhi glared at Li Zheng pretty and thought to herself that it would be fine if she said this in private, but she said this to her father in front of so many people.

Your Majesty is coming to Jingyang tomorrow.

It was in a hurry, and Li Zheng didn't want to let the whole village prepare overnight at this time.

Just clean up Li Shimin's villa in the village.

In Li Lizhi's account room, Li Zheng saw Li Lizhi's plan.

A new workshop was built on Bashang to make pulp.

The original papermaking workshop staff could use the printing process.

The key technology for papermaking is still in Jingyang, and the most important printing technology naturally cannot be spread.

Li Shimin must have eyes on these things, and he must have known it in his heart.

But paper is not a threat.

Because the external printing technology is still in woodblock printing.

Jingyang's movable type printing and assembly line technology are still exclusive, so Jingyang's printing technology is invincible.

Just as he looked at the map in front of him, Li Jiangshan's voice came from behind.

"The army of the Eastern Expedition is still three days away from Chang'an."

Hearing the sound, Li Zheng looked back at Li Jiangshan. Seeing that Li Jiangshan's clothes were soaked with sweat, Li Zheng handed her a piece of watermelon, "It's so hot."
