"Xianjing, an ancient feudal dynasty, even if it has a steam engine, how immortal can it be?"

Bai Lian laughed as she walked, Jin Zixuan saw that her expression was full of disbelief, and she said:

"Actually, at that time, I didn't think that Xianjing could surprise me in anything, but when I came to the wall of Xianjing City, I was already stunned!"

"The city walls?

I heard that the ancients liked to build the city wall high, but what is the use of the city wall high now?

Anyway, in front of the plane cannon, the city wall is just an ornament, except for looking interesting, nothing else is of much use, right?"

Jin Zixuan chuckled lightly and sighed:

"Well, normally speaking, the city really doesn't need walls now.

However, in addition to defense, the castle walls of Senkyo have a role that you can never imagine.

After entering the age of steam, a technology appeared in Senkyo in that dynastic world, called 'Cloud Ladder'!

This ladder is so interesting, in my opinion, it is even more comfortable and interesting than the urban traffic of our four countries.

And the city wall is one of the carriers of the ladder!"

Bai Lian'an's eyes widened curiously and asked:

"What is a ladder?"

Jin Zixuan slowly continued to tell her...

......

At that time, when the fool Jin Zixuan and Grandma approached the city wall, they were very surprised!

Along the way, thanks to the beautiful tour guide on the side to lead the way and explain, otherwise, Jin Zixuan would definitely not be able to enter the city.

After leaving this world last time, Zhao Gongming, the God of Wealth who is a replica of Jin Zixuan, has launched countless reforms one after another, such as the establishment of dozens of universities near the capital in the past few decades.

Speaking of these universities, they have cultivated talents for the country, and one of them is particularly famous, which is set up on the main road to the capital, and if you are not a resident of Senkyo, you must be reviewed by the tour guide academy if you want to enter Senkyo.

Only those who pass the examination can enter Senjing under the guidance of a university student guide.

Thanks to Jin Zixuan, he couldn't bear to have no one to take care of this elderly old woman, and took her all the way back to her hometown in the capital. This kind of behavior is seen in the eyes of college students, and instinctively adds a lot of impression points to him, so his review is very fast.

Of course, there is another reason that he has money!

In order to pass the review, and hoping to find a more knowledgeable guide, Jin Zixuan did not spend less silver tickets.

This classical beautiful girl wearing a cheongsam is a high-achieving student invited by Jin Zixuan when he passed by the tour guide academy. Because Jin Zixuan hopes to find someone who can take care of his grandmother, and can also answer and introduce more things he wants to know, so he is very generous.

Jin Zixuan did not tell Bai Lian about the journey of several months.

Regarding money, during the past few months of travel, Jin Zixuan has almost always driven Nianbo to search for gold, and everywhere he went, he exchanged the recently collected gold for silver tickets.

Anyway, there are means of transportation to facilitate transportation, so the total amount of gold sold by Jin Zixuan is very large, and all the months add up to make a small gold mountain.

......

After getting out of the car in the parking lot, the three of them went up the ladder.

The so-called ladder is a kind of escalator on flat ground.

Because it is driven by steam, the escalator always emits a faint water vapor, as if stepping on a cloud to move, so it is named a cloud ladder.

It is very similar to the horizontal escalators in the future airports, subways, and high-speed rail stations.

Compared with the electric escalator of the future, this horizontal escalator is much wider, and can accommodate four to five people side by side at the same time in one direction, and the speed is similar to that of the escalator of the future.

Holding Grandma to the nearest horizontal escalator belt, Grandma, who had never taken a horizontal escalator, was a little nervous, and her hand holding Jin Zixuan's arm tightened.

Helping Grandma to walk a few steps in the direction of the escalator's movement, when the walking speed was about the same as the escalator's speed, the three of them went up the escalator.

The classical beauty of the cheongsam beside her began to introduce gently:

"Each ladder here in the parking lot has a total length of more than 3 kilometers and moves at a speed of less than 1 meter per second, which is about the same as walking. If you take it from the outer edge of the parking lot, it takes you about an hour to get under the city walls. Our car was parked in the middle of the parking lot, so it took about ten minutes to get to the city gate. ”

Jin Zixuan nodded, they set off early today, but they were not in a hurry, and now the sun has just risen.

He walked alone on the spacious ladder, which, once he stood up, was as stable as the ground.

He looked to the other side of the ladder, which was reversed.

The ladder moves in two directions, under the city walls and on the periphery of the parking lot. The two directions are separated by handrails similar to those of the future escalator, and on the outer sides, there are only crutch-like handrails that are far apart, which can help people quickly adapt to the ladder.

You can walk up or down from anywhere in the middle of the entire ladder.

There are also a few horizontal ladders in the cities near Xianjing, but the scale is not as large as Xianjing, and there are no auxiliary crutch handrails on it that are convenient for the elderly to get up and down.

The classical beauty guide continued:

"There are now nearly 100 of these ladder belts on the periphery of Xianjing, extending from the edge of the parking lot to under the city gate, and the entire parking lot overlooks, like lotus leaf veins, cutting the entire circular parking lot into a fan-shaped area.

If you park on the outermost side of the parking lot, walk up to a few hundred meters to walk up a horizontal ladder belt.

However, there are not so many cars in the parking lot of Xianjing, and everyone tries to park in front of the horizontal ladder, so under normal circumstances, you can take the ladder within 100 meters. ”

Jin Zixuan nodded, in the future, he would rarely see such a long and convenient horizontal escalator.

However, these nearly 100 3-kilometer-long escalators are too wasteful of resources, right?

In the future, even if it is electric, it will not be built so unscrupulously...

With questions, Jin Zixuan continued to observe.

......

There is an endless stream of people coming and going to Xianjing, and there are also many people who go out of the city to find a car on the reverse ladder, and the closer you get to the city wall, the more people there are. Jin Zixuan looked at the opposite person, this oncoming feeling was even stranger than taking an escalator in the future... When we arrived at a position more than ten meters away from the city wall, the conveyor-belt-like ladder came to an end.

The tail end of the ladder is a turn, and if you don't get off the escalator, it will automatically turn half a circle and move in the opposite direction. Jin Zixuan helped his grandmother, walked a few steps in reverse under the guidance of the beautiful guide, and when the ground was almost relatively still, he easily went down the ladder.

Grandma breathed a sigh of relief, and Jin Zixuan also patted her on the back, and then looked up at the endless city wall of Xianjing.

The city wall is nearly ten meters high, and in addition to the soldiers patrolling on it, there are also many people who are visiting and watching.

Can the people go up to the city wall at will?

Waiting in line to enter the city for inspection, Jin Zixuan was a little entangled.

Xianjing is now a large city, I heard that the length of each direction is more than 20 kilometers, there are no cars and bicycles, and it should take six to seven hours to cross by normal walking!

It's too inconvenient, isn't it?

Regarding the fact that you can't drive, the beautiful guide's explanation is that there are ladders everywhere in the entire Xianjing, and people are like the gods in the clouds, almost don't walk much, and fly away at one stop on the ladder conveyor belt, and they don't need to drive at all.

When Jin Zixuan heard this, he felt even more unreliable... He asked rhetorically:

"The ladder is so slow, even if it can reach 1 meter per second, if we stand all the way from the east of the city to the west of the city, wouldn't it take nearly seven hours? Just now we took the ladder to walk less than two kilometers, and it would take more than ten minutes. This speed can't be compared to driving, huh?"

The beautiful guide smiled and said:

"It's your first time coming to Senkyo, so it's normal not to know.

In Xianjing, a lot of 'high-speed ladders' have been built, and you will know when we finish lining up and get on the 'ladders around the city'!"

Jin Zixuan blinked and said strangely:

"What are you talking about?

Hearing these escalators, Jin Zixuan wrapped his left arm around it, and held his chin up with his right hand and pondered.

The reason why cars are not allowed to enter Senkyo is probably because it is impossible to build an underground parking lot. He understands that today's people are not technologically adequate, and it is difficult to build underground parking lots without electricity and high-tech equipment. No matter how big the capital is, it can't accommodate so many vehicles across the country.

Even the small cities on the border have almost every car, so the capital must not be crowded with cars?

But what does the ladder mean in the whole capital?

The escalator in the parking lot outside the city has already made him speechless, could it be that these nearly 100 cloud ladders actually have ulterior motives?

How much fuel is wasted?

The energy utilization rate of steam-driven escalators is definitely much lower than that of electricity, not to mention that there are not many electric escalators in the future...

When it comes to electricity, Jin Zixuan is even more depressed!

I thought that after the steam engine was popularized by the whole people, someone should soon be able to develop electricity.

But unexpectedly, in 40 years, the steam engine has been carried forward, but the electricity has not yet been developed, and there is not even an electric light at night...

......

Thinking like this, the team finally lined up in front of Jin Zixuan and the others.

The line looked quite long, but it was actually only a few minutes.

As soon as the beautiful guide showed the information that Jin Zixuan had confirmed in the tour guide academy, the officers and soldiers defending the city quickly let him go.

The three of them walked a few steps into the city gate, and Jin Zixuan found that it was more than ten meters away under the city gate!

Is it necessary to build such a thick city wall?

It is estimated that even if you use a cannon to bomb a place outside, you won't be able to blow up dozens of cannons...

Seven or eight meters into the doorway, Jin Zixuan saw a large door open on the wall of the doorway, and inside the door was the appearance of a stairwell, and many people went in or out from here.

Jin Zixuan asked the guide curiously:

"This is the entrance to the upper wall, right?

The city walls and city walls of our Xianjing, the common people can actually go up casually?"

In the past, Jin Zixuan had also been to some ancient cities, and only the officials and soldiers in charge of city defense could go up to those city walls.

The guide smiled politely, made a gesture of please, and said:

Jin Gongzi said with a smile, come, we are just about to walk here, let's talk as we go.

Grandma come, I'll help you up the escalator, hey~ Be careful.

Jin Gongzi didn't seem to know that this city wall was originally built for the people.

Because, the 'Ring City Ladder' is built on the city wall!

This gate is Gate 271, and if we want to enter the Senkyo 2 Ring Road this time, we normally have to take the Ring Road Ladder to Gate 260, and then transfer to the 'high-speed Cloud Ladder' in Senkyo City. ”

Jin Zixuan frowned, what the hell are the ladders around the city and the high-speed ladders?

Talking about these two unfamiliar terms, Jin Zixuan bit his lip and didn't ask any more.

The three of them took the escalator up and down and slowly came to the top of the city wall from under the city wall.

It was like returning to the ground from a subway station, the sun was shining, and Jin Zixuan looked around curiously.
