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

Jiang Chuan said, "The subway!"

"Yay! We're going to take the subway!" Zhu Jingjing exclaimed excitedly. To her, this modern world was full of surprises.

Feeling the strange looks from passersby, Jiang Chuan was a little embarrassed. "Do you even know what a subway is?"

Zhu Jingjing shook her head slightly. She was new to the area and naturally couldn't know anything about the subway.

"I don't know what you're so excited about!" Jiang Chuan pouted. From a modern perspective, Zhu Jingjing was already a middle school student. It was really embarrassing to make such a fuss over taking the subway.

After walking along the road for a few minutes, the two finally arrived at the subway station entrance.

"Where is this down there?" Zhu Jingjing asked in surprise. In her mind, the only facilities built underground were storage cellars and tombs.

"Subway, subway, of course it's underground." Seeing her standing still, Jiang Chuan took her hand. "Don't shout when we go in, understand?"

He had a feeling that Zhu Jingjing would scream loudly when she saw the subway, so it was better to warn her in advance.

It's a small matter if she loses face, but it would be troublesome if the staff became suspicious and questioned her identity.

Zhu Jingjing nodded slightly in agreement, but when she saw the escalator, she completely forgot Jiang Chuan's instructions. "Wow! What is this? How come it's moving by itself!"

Jiang Chuan gave a wry smile, knowing she couldn't resist. "This is called an escalator, want to try it?"

Zhu Jingjing nodded repeatedly, broke free from Jiang Chuan's hand, and ran up the escalator.

Seeing this, Jiang Chuan quickly reminded him, "Don't move around, hold on tight, be careful not to fall!"

"Okay, okay, you're so nagging!"

Seeing the lively Zhu Jingjing, Jiang Chuan quickly followed, keeping a close eye on her to prevent her from encountering any danger.

Is this what it feels like to be an older brother?

He was an only child, and his several cousins ​​were all older than him, so this was the first time he had ever felt like an older brother.

"Come on, take a step." After getting off the escalator, Jiang Chuan was about to take her to buy tickets and enter the station, but unexpectedly, Zhu Jingjing turned around and walked up the escalator.

Although it was a bit childish, Jiang Chuan could understand it. He had done the same thing when he first saw an escalator as a child.

"Jingjing, stop playing. Aren't you supposed to go to the amusement park?" Jiang Chuan glanced at the time and reminded her, "We still need to look at furniture. If we take too long, the amusement park will close."

Upon hearing this, Zhu Jingjing, who was in high spirits, calmed down and started running down the escalator as if it were a staircase.

"Hey! No playing around on the escalator!" This scene was witnessed by a uniformed staff member, who stepped forward to stop them.

"Jingjing, stop right now. Wait until we get to the top before taking the escalator down!" After giving the instructions, Jiang Chuan quickly turned around and apologized, "I'm so sorry, my sister just came from the countryside and it's her first time seeing an escalator, she's a little too excited."

"It's fine to be a little excited, but we can't cause trouble for others." After saying that, the staff member turned and left.

Jiang Chuan breathed a sigh of relief, and after Zhu Jingjing came down again, he reprimanded her sternly: "From now on, tell me in advance what you're going to do, and don't act on your own anymore!"

Zhu Jingjing pouted, clearly unconvinced. After all, she was the little princess of the Ming Dynasty, and apart from her father and mother, who would dare not coax her properly?

"Why are you being so fierce! I was just being a little playful, is it really that big of a deal?"

Seeing her aggrieved expression, Jiang Chuan felt a little sorry for her, but he also knew that some things could not be compromised!

In modern times, Zhu Jingjing is no longer the spoiled little princess she once was. If we indulge her too much, it will only harm her.

"If you can't do it, then let's go home now! I won't take you out again until you're willing to listen!"

Zhu Jingjing sniffed, feeling wronged, but the amusement park was clearly more appealing.

She slowly lowered her head and gently tugged at Jiang Chuan's sleeve. "I'll do whatever you say..."

Jiang Chuan nodded in satisfaction and gently patted her head as a gesture of comfort.

The Great Tang Dynasty, Taiji Palace.

"What an amazing thing! People can move on their own just by standing on it. Wouldn't it be much more convenient if more of these were built in the palace?" Li Shimin was very impressed with the convenience of escalators and had even imagined what it would be like to use this technology in the palace.

"Father, this looks so interesting! I want to play too!" Compared to convenience, young Si Zi values ​​fun more.

Seeing that Zhu Jingjing was having fun, she naturally wanted to try it too.

"Issue my order: summon all the skilled craftsmen in the palace immediately!" As a pragmatist, Li Shimin immediately gathered the craftsmen in the palace, preparing to order them to study and replicate the work.

Three Kingdoms, new fields.

"Strategist, do you think this can be used to transport grain and supplies?" Liu Bei pondered. To him, the escalator was convenient but not essential. However, if it could be used to transport grain and supplies, it would be a completely different story.

Zhuge Liang pondered for a while before replying, "In my opinion, a stepped layout is not suitable for transporting goods. If it could be made horizontal, transporting grain and supplies would be a piece of cake!"

Liu Bei nodded repeatedly. Kongming truly deserves to be called a genius of his time; his words hit the nail on the head!

Liu Bei then asked, "Strategist, how does this compare to your wooden ox and flowing horse designs?"

Zhuge Liang smiled wryly and said, "The wooden ox and flowing horse are ultimately inanimate objects; they must be controlled by human power to move forward. How can they be compared to these?"

The Great Ming Dynasty, Fengtian Hall.

"That arrogant brat dared to yell at Jing'er!" Zhu Yuanzhang slammed his fist on the table, pointing angrily at the river in the sky, "If he makes Jing'er cry, I will punish him!"

Empress Ma chimed in from the side, "Chongba, in my opinion, it wouldn't be a bad thing to let him discipline Jing'er more! Jing'er has been spoiled since childhood, and we've really spoiled her rotten."

Zhu Yuanzhang put on a stern face and remained silent. He knew that what Empress Ma said made sense, but he couldn't help feeling unhappy that his daughter had been scolded by others.

Meanwhile, in modern times.

Jiang Chuan led Zhu Jingjing into the subway station. Although they were underground, the surroundings were brightly lit, which amazed Zhu Jingjing.

"Why are so many people gathered here when it's supposed to be underground?" Looking at the bustling crowd, Zhu Jingjing clung tightly to Jiang Chuan's arm, clearly a little nervous.

"In many cities, the subway has become the preferred mode of transportation for people, so naturally many people ride it," Jiang Chuan explained quietly as he held her close.

Zhu Jingjing seemed to be deep in thought, and asked, "What exactly is a subway? Can so many people fit on it?"

Jiang Chuan chuckled, "Don't worry, even if it doubled, it wouldn't be a problem at all!"

The morning rush hour had already passed, and in his opinion, there weren't many people at all.
