Sky Curtain: With a vermilion mirror, Jing travels through the modern world, shaking all dynasties.

"Jingjing, how are you feeling?" Jiang Chuan asked, holding Zhu Jingjing's hand as they walked out of the subway station. "Isn't traveling in this era much more convenient than in your Ming Dynasty?"

Zhu Jingjing bit her lip lightly and said, "Before I met you, I had never even left the palace. How would I know?"

Jiang Chuan was taken aback. Although Zhu Jingjing was a princess living a life of luxury, she could not escape the constraints of the palace and was firmly trapped in the Forbidden City.

"From now on, I will take you to travel all over the beautiful land of our Dragon Kingdom. Get ready to have your eyes opened!" Jiang Chuan comforted him softly.

Zhu Jingjing nodded, her heart filled with anticipation, eager to follow Jiang Chuan to see the sights she had never seen before.

"Let's go, we've arrived at the commercial district. Let's go buy you a bed first," Jiang Chuan said.

Zhu Jingjing then looked up and began to examine the commercial district.

Seeing the towering skyscrapers all around her, her eyes were filled with awe. "Brother, how tall are these buildings? Are they even taller than the Tengwang Pavilion?"

Jiang Chuan chuckled. Although Tengwang Pavilion is tall, its highest point is only sixty meters. How can it compare to modern skyscrapers that are often hundreds of meters tall?

"Jingjing, look over there!" Jiang Chuan pointed to a towering building that seemed to pierce the clouds in the distance, saying, "That's the tallest building in Yanjing, probably as tall as ten Tengwang Pavilions combined!"

"Really? What's it used for? Could it be for catching clouds?" Zhu Jingjing was very excited. She had been very curious about the clouds in the sky since she was a child. "I really want to touch it. I wonder if it will be as soft and fluffy as I imagine."

Jiang Chuan smiled wryly and explained, "Clouds are actually aggregates of a large number of water droplets and ice crystals suspended in the air, so they certainly won't be soft. That skyscraper is actually a building that integrates a series of services such as offices, conference facilities, commerce, and tourism. Its greatest significance should be to alleviate land scarcity, occupying the least amount of land and providing the most jobs."

Zhu Jingjing looked confused. As a princess who grew up in the deep palace, she had little understanding of the importance of land.

"Jingjing, do you know how many people there are in our Dragon Kingdom right now?" Jiang Chuan patted her head and asked.

Zhu Jingjing pondered for a moment and replied, "I've heard my father mention that the Ming Dynasty has about 60 million people. Now that I think about it, that's about right, isn't it?"

Jiang Chuan's expression was slightly serious as he gently shook his head. "Not at all! Our Dragon Kingdom has a population of 1.4 billion!"

"Fourteen billion... billion!" Zhu Jingjing exclaimed in shock. "The Ming Dynasty has a population of sixty million, and even Father Emperor worries about feeding the people. How are we going to feed fourteen billion people?"

Jiang Chuan asked with a smile, "Now you should understand how important land is, right?"

Zhu Jingjing nodded thoughtfully. She realized once again how amazing this modern society is. How can a population of 1.4 billion not only be fed, but also fed well?

As they spoke, the two arrived in front of the furniture store.

"Jingjing, let's go in quickly. Just pick a bed you like." As a military industry genius of the Dragon Kingdom, Jiang Chuan still has a lot of savings, so buying a bed that the little princess likes is no problem for him.

"I remember the third floor sells beds. We don't have much time today, so let's not look at anything else and just take the elevator up." With that, he led Zhu Jingjing to the elevator.

"Elevator?" Looking at the tightly closed iron door in front of her, Zhu Jingjing pointed to the constantly changing numbers beside her and asked, "What's going on with these numbers? Why are they getting smaller and smaller?"

Seeing that the elevator was about to reach the first floor, Jiang Chuan was in no hurry to explain and let her experience it first.

As the elevator doors opened, Zhu Jingjing watched the passengers leave with a suspicious look before asking, "Brother, did those people make a mistake?"

Jiang Chuan was taken aback. What was this all about? How did it relate to making a mistake?

He asked with a smile, "Jingjing, how do you know they made a mistake?"

Upon hearing this, Zhu Jingjing replied, "If they haven't done anything wrong, why lock them in such a small room?"

Jiang Chuan chuckled, "That's right, it's our turn now. Let's go in!"

Zhu Jingjing shook her head repeatedly, clinging to Jiang Chuan's arm and refusing to let go. "No, Jingjing did nothing wrong, I don't want to be locked up!"

"You have no choice in this!" Jiang Chuan said without waiting for a reply, picking her up by the waist and carrying her into the elevator.

After he pressed the button for the third floor, the elevator doors closed again, and Zhu Jingjing was finally put down.

"Brother, Jingjing..."

Before she could finish speaking, the elevator suddenly shook, and Zhu Jingjing instantly turned pale.

"Brother, I know I was wrong, please forgive Jingjing!" Experiencing the gravitational pull of an elevator for the first time filled Zhu Jingjing with inexplicable fear. "I'll never tell Godmother again, please forgive me!"

"Don't be afraid, Jingjing, this is the elevator. We'll be out soon," Jiang Chuan quickly reassured her. Otherwise, if she kept shouting like that, she would attract the security guards sooner or later.

"Really?" Zhu Jingjing had barely finished speaking when the feeling of weightlessness from the elevator slowing down made her stumble. If Jiang Chuan hadn't caught her quickly, she would have fallen.

When the elevator doors opened again, Zhu Jingjing rushed out as if fleeing.

"This is..." She was utterly shocked. She had come out of the same door, yet the scene outside was completely different from before...

The Qin Dynasty, Xianyang Palace.

"Could this be some kind of magic?" Ying Zheng's eyes widened in disbelief. "We've arrived at another place in the blink of an eye! Is this the legendary 'shrinking the earth to an inch' technique?"

The alchemist Lu Sheng, standing nearby, was so astonished that he bowed down in worship, but instead of worshipping the First Emperor, he bowed to the celestial dome above.

Three Kingdoms, new fields.

"Strategist, what is this?" Liu Bei was equally shocked. "What's so special about that small room that it allows for instantaneous teleportation?"

After pondering for a while, Zhuge Liang shook his feather fan again and said, "My lord, in my opinion, this might be similar to the escalator!"

Liu Bei suddenly realized and sighed, "What the strategist said is very true. If the strategist had not pointed it out, I am afraid I would have spent my whole life without understanding why."

Zhuge Liang sighed and said, "My lord's words have made me feel ashamed! I compare myself to Guan Zhong and Yue Yi, but I can only see the surface and cannot see the underlying principles."

Upon hearing this, Zhao Yun stepped forward with his hands clasped, "Strategist, please don't say that. Such an ingenious mechanism would probably be impossible for even Guan Zhong and Yue Yi to see through."

Modern furniture market.

"Brother, I understand!" After witnessing the various technologies of modern times firsthand, Zhu Jingjing finally got it. "Just now in that small room, I felt like I was rising. It wasn't teleportation; we just went from the first floor to the third floor, right?"

Jiang Chuan nodded in surprise. This little princess was quite clever; she actually figured it out on her own this time.

"Jingjing, this third floor is all beds. Pick whichever one you like!"
