The commercial city has just opened, and it has proved its prosperity.

The operating rules of the shop are gradually spreading, and many businesses have begun to register, waiting for the next round of elimination to get ahead!

After having a bus, it also provides a lot of convenience for people's lives!

A penny can not only move in Xianyang City, but also go to the commercial city!

The lottery business is getting better and better day by day, with the total sales every day being around 400,000 gold!

Under careful care, Xiao Yiyi grew fatter and chubby, like a small pink ball.

When the full moon wine was held, all the civil and military officials gave a lot of gifts.

Ying Heng took advantage of the opportunity to drink the full moon wine and asked Ying Feiyu about some things about the speakers and phones!

Ying Feiyu answered one by one and asked him to study it slowly.

And he also reminded that the audio is not very effective, and the focus of research should be on the phone!

After researching the phone, you can call instantly thousands of miles apart.

Whether it is the court conveying orders or the people talking to their families, it can be more convenient!

Ying Heng agreed with a smile.

But according to Ying Feiyu's estimate, this kid will definitely not give up on both sides.

This guy has a sudden force and will not give up until he achieves his goal!

Of course, scientific research also requires such talents!

If you are the kind of person who retreats when encountering difficulties, you will not be able to find anything!

As for Huang Yuan, he left after giving the gift and didn't even eat the banquet in the palace.

It is said that the batch of air conditioners built in advance will be offline soon, so he has to go back and supervise it quickly!

During this period, he was so busy that he hit the back of his head, and he had no free time at all!

As for commercial cities and lottery stations, I don’t have time to pay attention to them!

Only when the bus was officially running, I took the time to observe for a while and confirmed that there was no accident and it was as smooth as the trial run. Then I returned to the factory with peace of mind!

Both types of air conditioners are being produced, and he has many things to be responsible for.

At the same time, there are refrigerated trucks that he needs to study, so he doesn’t care about anything else!

“The air conditioner is about to be built?”

When Ying Zheng learned about this, his eyes lit up.

"Yes! Huang Yuan really said that!"

After Huang Yuan left, Ying Feiyu mentioned to Ying Zheng, and the scumbag immediately became interested.

"It just so happened that the weather was hot, so I turned around and asked him to install Yuxiu Palace quickly! If it was not good to build again, summer would be over!"

Ying Zheng can't wait.

"good!"

Ying Feiyu nodded and agreed.

...

Three days later, Ying Zheng and others sent all the cars to the car factory and asked craftsmen to install air conditioners for their cars.

At the same time, the home air conditioners ordered by veterans have also begun to be installed by craftsmen.

When the installation was done, all the old people in the old mansion came to watch.

Everyone has only heard of this thing that can bring cool breeze, but has never really seen it. They stared at the craftsman's movements with curiosity!

After the craftsman leaves, turn on the electricity immediately and use it according to the method assigned by the craftsman!

After feeling the cold wind blowing from the air conditioner, I was amazed!

The same is true for Lian'er, watching the craftsmen install it in a novel way!

"Let's wait and see. After the installation is completed, power is turned on, the whole room will become refreshing and cool!"

Ying Zheng had seen the air conditioner and was proudly explaining to Lian'er.

“Cooler than ice?”

Lian'er blinked, looked at the strange big box in front of her, and asked suspiciously.

Every winter, the palace will store some ice cubes for summer relief.

With Ying Feiyu's saltpeter ice making method, as soon as the summer sky came, all palaces used ice cubes!

Ice melts and absorbs heat to cool down!

"It's like being on top of ice!"

Ying Zheng described it in no exaggeration.

Air conditioners can adjust the temperature. When the temperature is adjusted to the lowest temperature, it is almost the same as being in ice!

"Can it be so cool?"

Lian'er was quite shocked.

"Yes! I didn't expect it before, and I couldn't believe it until I experienced it myself!"

Ying Zheng opened his mouth and smiled so brightly.

"Your Majesty, the air conditioner has been installed and can be used!"

As soon as he finished speaking, the craftsman began to pack up his tools and report.

"Yeah! OK!"

Ying Zheng nodded slightly and responded.

After the craftsman packed up, he immediately stepped out.

"Close all the doors and windows!"

"Why did Brother Zheng close the doors and windows?"

Lian'er was puzzled by the order issued by Ying Zheng.

In such hot weather, if you don’t open the doors and windows to get some air, you will be suffocated to death!

"This air conditioner will produce cold air. If the doors and windows continue to be open, the cold air will drill out along the doors and windows, and the cooling effect will not be achieved!"

These are all what Ying Feiyu said at the beginning, and Ying Zheng just copied it.

"I see!"

Lian'er nodded in understanding.

After a while, the doors and windows were closed tightly. The eunuch turned on the air conditioner and adjusted the temperature according to the method taught by the craftsman just now!

Immediately afterwards, a gust of cold wind came out of the machine!

"Oh! It's really cool!"

Feeling a hint of coolness, Lian'er couldn't help but exclaim.

"Yes! The air conditioner can not only cool down, but also heat up! When autumn comes, if you feel the room is cool, turn on the air conditioner to keep warm!"

“Can you still keep warm?”

Lian'er was even more surprised.

"Yes! Feiyu's research is really good this time! In addition to household air conditioners, he can also install air conditioners on the car! My car has been sent to the car factory for modification, and it is estimated that it will be completed in no time! When driving in the future, I won't be afraid of heat!"

Thinking of this, Ying Zheng’s smile even more.

"That's great..."

Lian'er smiled like a flower, "It would be great if the people could use the air conditioner!"

Influenced by Ying Zheng and Ying Feiyu, Lian'er will also think of the people when encountering any novel things.

"This...is still a little difficult!"

Ying Zheng shook his head and continued, "Not to mention the price of air conditioners, first of all, people must turn on electricity at home! Air conditioners rely on electricity, and they cannot do without electricity at all!"

Although electricity has been popular for many years and the household entrance fee has been reduced from 5,000 yuan to 1,000 yuan, ordinary people still cannot afford it.

This household registration fee alone stumped them!

The strength of Daqin has not yet reached the point where it can install electricity for every household.

"Yes! Now only those wealthy households can use electricity, but ordinary people cannot do it! My Qin Dynasty still needs to continue to develop!"

Lian'er said with emotion.

"In that kid's words, you can't eat a fat man in one bite. Daqin must fight steadily and develop slowly! Now that foreign enemies have been eliminated, it is a matter of time to develop!"

Ying Zheng was not worried about this.

It would be great to be able to eliminate those foreign enemies and let the people live a stable life!

As for these various machines, they are all assisted in life.

Of course it is better if there is, and it will not affect the normal life of the people!

"Um!"

Lian'er nodded with a smile.

"Come on! Let's continue to arrange hotpot for lunch today!"

"yes!"

The temperature inside the house dropped, Ying Zheng was in a good mood, so he waved his hand and issued an order.

Since the beginning of summer, even if he lies still, he is sweating all over and the food is as light as possible. He hasn't eaten hot pot for a long time!
Chapter completed!
