"Princess Changle, Empress Zhangsun, let me teach you how to use the things in the house."

Su Xingwan walked to one side of the living room and pointed to a switch on the wall. "This is the light switch. Press it once and it turns on, press it again and it turns off."

"I never imagined that future generations would have it so convenient. And this electric light is so bright, making the whole room as bright as day. It is truly magical," Empress Zhangsun marveled.

"And this is the television."

Su Xingwan led them to the coffee table in the living room, picked up the remote control, and pressed a button while pointing it at the TV. "This is the power button, this adjusts the volume, and this changes the channel."

"Sister Su, why are there people inside this television?" Li Lizhi couldn't help but ask.

Empress Zhangsun added, "Indeed, it looks as if there are real people inside."

Su Xingwan smiled. "It's a bit complicated to explain. Just think of it as a shadow puppet play."

Saying this, she pointed towards the kitchen. "That's the kitchen over there. You don't need to cook your own food; you can just eat at our place from now on. The fire in the kitchen uses gas, which is a bit dangerous, so it's best not to go in there unless necessary. If you are really curious, I can come over and teach you how to use it when I have some free time."

"Come, let's go check out the rooms," Qin Fei said, leading the way.

Soon, the group arrived at a room on the second floor of the villa.

"Wow, it's so pretty here! Sizi wants to live here," the little princess in Gu Siyu's arms said excitedly.

While they were eating earlier, Xia Fei and the others had specially arranged for someone to come over and decorate. This room was prepared exactly for Little Sizi, filled with lots of toys and plushies.

"This is Sizi's room," Gu Siyu said with a smile, gently pinching her cheek.

Jiang Yanran spoke up, "Changle, why don't you sleep in this room too? Little Sizi is still young and needs someone to watch over her."

"Alright." Li Lizhi nodded. She was also very pleased and satisfied with the layout of this room.

Su Xingwan said, "Every room has its own independent bathroom, complete with a bathtub."

Saying that, she led Empress Zhangsun and Li Lizhi into the bathroom. "Twist this and water comes out. To the left is cold water, to the right is hot water, and the temperature can be adjusted."

"This is too convenient. Just a twist and water flows, and you can even adjust the temperature. Life in the future is simply too wonderful."

Ever since following Qin Ning here, they suddenly realized that their life in the Great Tang's imperial palace was actually quite terrible.

"Empress Zhangsun, this is the room for you and His Majesty." Jiang Yanran led them to another room next door. This was the master bedroom; it was much larger, and the overall layout appeared far more luxurious.

"When His Majesty returns later, he will surely love it too."

Empress Zhangsun nodded in great satisfaction, then looked at Qin Fei and the others. "Thank you all for going to so much trouble."

"You're welcome."

Everyone replied with a smile, feeling that everything happening today was quite a novel experience.

Yang Xin added, "It's only a little past eight o'clock. Why don't we go out for a stroll?"

"It's already dark. Sister Yang, do you not have a curfew here?" Li Lizhi asked curiously.

"Of course not."

Yang Xin laughed, "Besides, things only start getting lively here at night. Do you want to go take a look?"

Hearing this, Empress Zhangsun and Li Lizhi exchanged a glance, then nodded. "Since we have the opportunity to visit the future, we naturally must go and see it."

If it were before, she might have just gone to rest. After all, Empress Zhangsun had always been in poor health and was not suited for overexertion.

But ever since Qin Ning helped treat her, Empress Zhangsun now felt an unprecedented sense of relief. After a whole day, she didn't feel tired in the slightest.

"Then Weiyang and I will go get the cars," Su Xingwan said.

Because there were quite a few people, one car wouldn't be enough, so they had to take two cars out.

Soon, the group arrived outside the villa. Seeing two vehicles parked in front of them, Li Lizhi was surprised again. "Are these the carriages of the future? Why are there no horses?"

"These are called cars. They consume gas and can run on their own without needing horses to pull them."

Qin Fei explained, then pointed to the other vehicle behind it. "This is also a car, or rather an electric vehicle. It runs on electricity. Electricity and gasoline are both forms of energy. If your Great Tang wants to develop technology in the future, oil and electricity will be absolutely essential resources."

Soon, after everyone got in, Cheng Weiyang's car took the lead, carrying Empress Zhangsun, Princess Changle, and Little Sizi, along with Qin Fei. The rest, including Yang Xin and Jiang Yanran, rode in the second car behind them.

The cars drove out of the villa district and onto the bustling main streets.

The brightly lit streets and towering skyscrapers everywhere once again left Li Lizhi and Empress Zhangsun in endless amazement.

"We couldn't see it from the house earlier. I didn't expect the outside to be so prosperous. Sister Qin, are all those lit buildings inhabited by people?" Li Lizhi couldn't help but ask.

Qin Fei smiled and nodded. "Yes, they are. However, some of them are office areas, which are places where people go to work, so no one lives there."

...

Meanwhile, inside the villa.

Qin Ning had already returned to his room, leaving Li Shimin, Xia Fei, Wang Er, and the others still drinking there.

"Brother, stop bragging. It's not like our Great Tang doesn't have spears. When I was conquering the world back in the day, I wielded one countless times. How could a spear be as exaggerated as you say?" Li Shimin laughed heartily.

Xia Fei replied, "The spears of your Great Tang and the guns we have here are not the same thing. The ones we have here are all firearms. From hundreds of meters away, they can just shoot you down."

"How far is a few hundred meters?" Li Shimin asked curiously.

"You can understand it as a few hundred paces, roughly half a mile."

Xia Fei chuckled and continued, "Besides, a few hundred meters is actually just average. Sniper rifles are the truly long-range ones. If I remember correctly, the world's longest confirmed sniper kill is over 3,500 meters, which is about seven li."

"Brother Li, just imagine. If I were holding such a gun, standing seven li away, I could shoot you dead in an instant. Aren't you afraid?"

Hearing this, Li Shimin couldn't help but shudder, sweat breaking out on his forehead. He then said, "I remember before coming here, Young Master Qin told me that you have something called an inter-something missile. Its range can reach thirty thousand li, and its power is so astonishing that it can instantly level a city with a population of a million to the ground?"

"That's called an intercontinental ballistic missile. It's a true pillar of the nation's military power, launched from land bases. It's not the same thing as a gun."

Zhou Ping'an felt that explaining it like this was somewhat troublesome, so he simply took out his phone, found an educational video about modern weapons online, and showed it to Li Shimin.
