Fans and Air Conditioners

"Good, good, good."

Hearing this, Li Shimin was a little excited.

Electricity was the foundation of everything.

Tonight, the entire city of Chang'an would be illuminated.

This was the beginning of a leap forward in the development of their entire civilization.

When the car drove to the city gate, they saw a tricycle driving over. It was Wang Yousheng.

Qin Ning and the other two got out of the car, and Wang Yousheng quickly came over to greet them. "Young Master Qin."

"Are there enough solar lights?" Qin Ning asked.

"For now, it's enough. Another batch was just transported over from the portal. Today, we'll first install streetlights all over the streets of Chang'an. Tomorrow, we'll run wires into the houses so that every household in Chang'an can have electricity. In addition, we have to get people to popularize basic knowledge about electricity. At the very least, we must let the common people know that electricity has a certain level of danger," Wang Yousheng said.

Qin Ning nodded and glanced at his tricycle. He saw some things loaded in the back. They looked like air conditioners.

"These are being taken to the imperial palace for installation. There are also over a dozen fans in the back. The weather is hot now, so the students can use the fans to cool down during class."

"As for the air conditioners, they are to be installed in the teachers' dormitories. After all, they came from the future and have never suffered like this before. This is countless times harder than poverty alleviation work. Letting them have air conditioning is the best condition we can provide at the moment," Wang Yousheng said.

As he spoke, a voice came from the walkie-talkie at his waist, "Captain Wang, have the fans been brought over? My students here are about to die from the heat."

"Coming, coming, on the way." Wang Yousheng picked up the walkie-talkie and replied, then drove the tricycle all the way towards the imperial palace.

Qin Ning drove his car, following behind with Li Shimin and Empress Zhangsun.

Not far inside the palace gates, a few side rooms had been temporarily cleared out and divided into individual classrooms. The knowledge taught in each classroom was different.

The wires had just been laid out, so now as long as the fans were brought over, they could be used immediately.

In the classrooms, despite the sweltering heat, everyone was very eager to learn.

Seeing Wang Yousheng appear, a teacher wearing glasses on the podium shouted to the students below, "Cheng Chumo, go help move the fans in."

"Yes, teacher."

A tall, dark-skinned young man wearing linen clothes stood up.

This was Cheng Yaojin's son, Cheng Chumo. Now, in the sixth year of the Zhenguan era, he was about twenty years old.

Soon, the fans were moved into the classroom and plugged in. The moment the fans were turned on, everyone felt an unprecedented wave of coolness.

"Is this an electric fan?"

"It spins just by having electricity? This is truly amazing."

Many students gathered around with curious faces. Today they had learned a lot about electricity and understood some of the principles. Now, seeing the electric fan spinning with their own eyes, they also understood the convenience that electricity could bring.

"I also brought air conditioners to install in your dormitories. Call someone to help me," Wang Yousheng said to the teacher on the podium.

"Alright."

The teacher nodded. "Cheng Chumo, you go."

"Yes, teacher!"

Cheng Chumo responded and then excitedly helped Wang Yousheng unload the indoor and outdoor units of several air conditioners from the tricycle.

Out of curiosity, Li Shimin also wanted to follow and take a look.

Inside a dormitory room, Wang Yousheng measured the position, then drilled holes. After setting up the outdoor unit outside, he brought a ladder, preparing to install the indoor unit on the wall inside the room.

Cheng Chumo helped hand over tools the entire time. Then, he lifted the indoor unit high and handed it to Wang Yousheng on the ladder.

Looking at Wang Yousheng, who had been busy for a long time and was already covered in sweat, Cheng Chumo could not help but ask, "Master, what line of work are you in?"

Wang Yousheng turned his head, just glanced at him, and did not speak.

Soon, after the air conditioner was installed, Wang Yousheng picked up the remote control and adjusted the temperature.

Feeling the cool breeze blowing out from the air conditioner, Li Shimin could not help but say, "Say, are there any more of these air conditioners? How about installing one in my sleeping quarters later?"

"Yes, they are continuously being sent over from the portal. Later, when I run the wires over to install the electric lights for you, I'll install an air conditioner for you along the way," Wang Yousheng said.

"Good, good, good."

Li Shimin laughed heartily. In this era, being able to use electric lights and enjoy air conditioning was already an incredible thing.

Soon, Wang Yousheng held the walkie-talkie and spoke to the people in the base outside the city, asking them to transport more light fixtures and air conditioners to the imperial palace using the tricycles.

Empress Zhangsun, on the other hand, ordered people to prepare food, intending to properly entertain Qin Ning, Wang Yousheng, and these teachers from the future later.

Before long, officials like Cheng Yaojin and Changsun Wuji also arrived, watching Wang Yousheng install the air conditioners and electric lights the entire time.

It was not until sunset, after all the lights in the palace were installed, that Yuchi Gong finally could not help but ask, "Your Majesty, what are these things used for?"

"You will know later."

Li Shimin laughed heartily and did not explain the air conditioners to them, saving himself the trouble of these old fellows wanting to install one in their own manors later.

It was not a problem of not having enough air conditioners, but rather that there was not enough electricity at present. Relying solely on solar photovoltaic panels could at most support the lighting of Chang'an City.

He would let them consider these things after the wind and hydroelectric power facilities were built in the future.

In the palace, next to the Lingyan Pavilion, at the top floor of a tower.

This was the highest building in the palace. Looking down from here, one could clearly see the entire imperial palace and the full view of Chang'an City, taking in everything at a glance.

Li Shimin had people set up a banquet here. In addition to officials like Cheng Yaojin, Qin Ning, Wang Yousheng, and those teachers from the future were all invited over.

"I'll have someone send some liquor over."

Just as Wang Yousheng sat down, he smelled the liquor in the jug and felt it was lacking.

Coming to the Tang Dynasty this time could be considered a kind of vacation for him. Since he was going to drink, he naturally had to drink the good stuff.

Saying that, he took out the walkie-talkie on him and asked the people in the base outside the city to help send over a box of Maotai.

"This walkie-talkie is really convenient. You can directly contact people outside the city from right here. I wouldn't have even dared to imagine this in the past," Changsun Wuji could not help but say.

Cheng Yaojin said, "Indeed. In the past, when we fought wars, we had to rely on scouts traveling back and forth to deliver messages. Now with walkie-talkies, it's incredibly convenient."

Fang Xuanling said, "Your Majesty, there must have been at least a thousand of those walkie-talkies yesterday, I wonder..."

Li Shimin naturally knew his thoughts and shook his head. "I understand that all of you beloved officials want a walkie-talkie, but this gadget must currently be used primarily on the battlefield to exert its greatest effect. Later, when we have more walkie-talkies, I will consider allocating one to each of you."

"Good, good, good. If that's the case, does that mean we won't have to attend court in the future? When the time comes, I, Old Cheng, can just sit at home drinking liquor and directly discuss state affairs using the walkie-talkie."

Hearing this, Wei Zheng immediately started scolding, "State affairs are not child's play, how can you act like this? Your Majesty, Duke of Lu..."

"Hold it right there. Just save your breath for today," Li Shimin interrupted directly.

At this moment, Wang Yousheng spoke up. "They are just walkie-talkies. You can have as many as you want. I will have someone deliver another thousand units to you tomorrow. Furthermore, the communication base stations around Chang'an City are scheduled to begin construction in the coming days. By the time they are finished, you will even be able to discuss state affairs through video calls. Walkie-talkies are nothing in comparison."

"Video calls? What might those be?" the assembly of ministers asked, their curiosity piqued.

Following that, Wang Yousheng gave them a brief explanation of some technologies from the future.

Although the crowd could hardly understand a word, feeling as though they were listening to an incomprehensible heavenly script, they were still profoundly shaken to their cores.

Soon, the liquor was brought over. It was a massive, brimming box of Maotai. Wang Yousheng handed out a bottle to every person present.

"This, this... this is actually made of precious glass?"

The crowd picked up the liquor bottles and examined them closely, looks of sheer astonishment plastered across their faces.
