Cross the collapsing iron and rebuild Yaliluo

Walking through the endless desert, the surrounding scenery is the same.

The sun was shining brightly on the sand, and the heat was steaming, as if it was about to swallow everything.

In this endless golden sand sea, the undulating sand dunes are like waves of the earth.

The vehicle does not drive directly in the desert, but on a patchwork of suspended roads.

Xia Zhihui looked at the lifeless desert and asked subconsciously.

"Why is there nothing in this desert?"

March 7th curiously stuck out his head and looked down.

"There is nothing in the desert. Isn't this normal?"

"Really? In my impression, there are many animals and plants in the desert, such as gerbils, desert foxes, cacti, etc., but I haven't seen anything in this desert."

"Oh? Xia Zhihui, have you been to other worlds and seen deserts?"

Xia Zhihui fell silent for a moment. It was hard for him to say. Desert Desert watched the live broadcast on the Internet in his previous life, right?

But every second he realized that he had indeed seen the desert, but he didn't stay there for long.

"Of course I have seen it. When I was sent to Dimeng Star by Silver Wolf, I fell in the desert. Thanks to Kandor dragging me back, I didn't get tanned."

"Oh, yes, you told me."

Listening to their chat, Aunt Boer said without looking back.

"The Silent Desert is different from the natural deserts you have seen. This is a man-made desert, used to isolate the townspeople from City No. 7."

"When City No. 7 was founded, it harvested the resources of many towns, which triggered riots."

"It was a bloody conflict with far-reaching consequences. Many people died. City No. 7 was able to suppress it with great difficulty. Later, it changed the city planning and reduced communication with the town."

Ok?

This is something Xia Zhihui had never expected. Aunt Boer actually understands history?

Seeing his eyes light up, March 7 smiled in Xing's ear.

"Xia Zhihui has begun investigating the cause of the star core."

"Last time in Luofu, I fought the Demon Yin Body, and then the Secret Medicine King, batch after batch, and finally the Great Lord of Extermination. I was exhausted from the beating."

"This time he is here, we can win again!"

Star also nodded.

It's not like there were no fights when we were at Yaliluo No. 6.

Successively defeated Silver Mane Iron Guard, World Splitting Creation, Swaro, Pella and Cocolia.

But basically it’s all done once, Luofu is endless batch after batch.

After all, the King of Medicine who is prepared to fall into the devil's body is really not afraid of death!

Xia Zhihui didn't pay attention to the two people's muttering, but looked at Aunt Boer who was driving.

"Aunt Boer, have you taken advanced education courses?"

"No, I passed the examination for primary education. The cost of subsequent intermediate and advanced education is too high. I still have to support my family!"

"Then how do you know the history of this man-made desert?"

Aunt Boer casually dialed in the autopilot and simply turned around to chat.

"You kid, you look very smart, why are you asking such a stupid question?"

"This year is the 217th year of the Final Machine Era. The Perfect Era ended just over two hundred years ago, and City No. 7 was founded only about a hundred years ago. That bloody conflict happened when my grandfather was young."

"People in the town tell it from mouth to mouth. I also heard it from my parents, so of course I know it."

Xia Zhihui was embarrassed for a moment and didn't know what to say.

Dan Heng came to the rescue.

"This suspended road seems to be going uphill. Why do I feel like it's getting higher and higher?"

"Of course it will drive higher and higher. We want to enter City No. 7 from above."

Above?

Karl said before that City No. 7 is an almost closed city, and it is even more of a line.

Xia Zhihui frowned.

"If you enter from above, why haven't I seen City No. 7 yet?"

"To be fair, we are already twenty meters above the ground, and there is no obstruction in the desert. Why can't I still see City No. 7?"

Karl was rubbing his shoulders. When he heard these words, he quickly pointed to a black spot in the sky.

"Look there!"

"That's the entrance to City No. 7."

"City No. 7 is a linear city. The exterior walls are made of mirrors made of special materials. They are not only strong and resistant to corrosion and friction, but they can also reflect the sun's rays and ensure a constant temperature inside."

"Actually, City No. 7 is already within our field of vision, but from the car we can only see the reflected desert and us on the suspended road."

On March 7, Dan Heng and Ji Zi just nodded slightly.

They have experienced a lot of the world and have a high degree of acceptance of different civilizations.

Xingxing wanted to jump out of the car eagerly, but March Qi hugged her waist decisively.

Only Xia Zhihui is thinking repeatedly about life. This urban form has completely broken his inherent cognition.

It is not so much a city as it is composed of two parallel skyscrapers, more like a mirror wall surrounded by a glass curtain wall.

But if you think about it carefully, it seems not unreasonable to build such a city in a man-made desert.

The first is safety. If the surrounding towns want to attack City No. 7, they will have to cross the desert, so the people in City No. 7 will be prepared early.

The second is resources. As long as the city is built along the flow of groundwater, it can ensure sufficient water resources in the city, thereby cultivating natural landscapes in the city and building a livable oasis in the desert.

Then there is the maintenance. As long as City No. 7 is perpendicular to the direction of the monsoon, it can ensure that the city's maintenance costs are low in the face of sandstorms with the least contact surface.

Finally, there is urban planning. Ordinary cities are made up of block-shaped areas and are flat cities. City No. 7 is designed for vertical stratification of different classes.

In different civilizations, cities of different shapes are formed. This is the norm.

After thinking about this, Xia Zhihui raised his head, and March Qi asked the last question thoughtfully.

"Why, Karl, when you talked about the guys in City No. 7 before, did you always describe them in terms of a few rings instead of a few layers?"

Carl shook his head.

"I do not know either."

Xia Zhihui slapped his seat, hating that iron could not make steel.

"You're stupid! Because they call it that from City 1 to City 6, they call it that too!"

"Am I right, Aunt Bell?"

Aunt Boer nodded with a smile.

"Indeed."

"I have never been to what other cities are like, but according to my grandfather, they are big towns that are much more advanced than Barlow Town."

"Actually, Barlow Town is very close to City No. 7. Look, we'll be there within a short while of chatting."

The outline of the entrance can already be faintly seen in the sky.

Xia Zhihui looked at Ji Zi who took out a handkerchief to wipe her sweat, and handed over a glass of frozen drink.

Ji Zi took it, took a sip, and handed it to March Qi.

On March 7, it was handed over to Xing.

"I want tea! I want the Immortal Happy Tea from Luofu, with ice."

Xia Zhihui's face froze.

"No, this is not available on the train."

"Don't make trouble. I saw you buying several glasses when I was in Luofu. At worst, I'll share the juice with you."

March 7 indeed stored a lot of juice in Xia Zhihui's backpack.

Xia Zhihui had no choice but to hand her the Immortal Happy Tea with ice and less sugar.
