"Can you fly!?"

Everyone in the room stared wide, looking in disbelief.

The third generation Fengying took a deep breath and asked tentatively: "Do you mean the entire city?"

"That's right."

"This is impossible!"

With a clear answer, Chiyo seemed to hear something ridiculous and shouted: "Do you know how big our Sand Hidden Village is?"

"Since I have made urban design, I will naturally investigate the relevant information." Long Er shrugged, "It's about 3,000 square kilometers!"

What is the concept of more than 3,000 square kilometers?

Almost half a Shanghai area.

Yes, you heard it right.

In terms of scale, Satsuki is only a small ninja village, and it is half as big as Shanghai.

Ninja Village... Although it is named after the village, it is actually a city-level scale regardless of population or area.

The largest Konoha village in the ninja world is several circles larger than the entire Shanghai (including suburban townships).

In such a big city, someone tells you that he can fly.

Do you believe it?

Anyway, Chiyo doesn't believe it.

No, no one here believes it.

"Since you know that the city is so big, how dare you say it can fly?" Chiyo stood up and asked: "Mechanism... To put it bluntly, it is a technique that saves manpower and completes great things with small amounts.

But even in small places, the source of triggering conditions is needed. The larger the thing, the larger the source of the required one.

A windmill needs wind to blow, and a watermill relies on the flow of water... What should your city do to make it fly?

Tailed beast?

I'm afraid it's not enough!"

"No, the chakra of the tailed beast is enough." Long Er sat upright and explained with a smile: "When I designed the government city, I referred to the space science. The city is crater-shaped, and it is distributed from low to high to residential areas, military areas, administrative areas, commercial areas, agricultural areas, industrial areas, garbage disposal areas... Although the overall area has been reduced to more than one thousand square kilometers, people's living space has become larger, and the population will be doubled in the future."

"I don't understand this." The third generation Fengying asked, "It's clear that the total area has shrunk by 2/3, why is the living space even larger? What does this space science mean?"

Hearing this, others also looked over.

Not only did the three generations of Fengying not understand, they were also confused.

Seeing this, Long Er opened his mouth and finally sighed deeply.

"Space study is a realistic rule I have summarized. It is like your room. If you put the furniture randomly, the room will become messy and the area will become smaller. However, if you place it in a regular and neat manner, you will free up a lot of extra space. I call this phenomenon space study."

Ah! That's it?

Everyone was a little confused.

They heard Ryuu Er talk about space learning before, but they thought it was a high-level theoretical knowledge of space ninjutsu.

The result is just a common phenomenon in daily life.

At the same time, they also felt suspicious.

"But no matter how rationally planned it, it would be too exaggerated to make 2/3 of the space. I often clean up my home and have never made such a large amount of space."

"How big is your home? How big is a city? Have you ever used formulas to make the most scientific space allocation?" Long Er rolled his eyes and interrupted Chiyo who wanted to say something, and said, "Anyway, there is no need to question this aspect. Anything you understand, and whatever you don't understand is in vain. The drawings are here. Look carefully and savor it carefully."

Upon hearing this, Chiyo immediately shut up.

The other party said everything to this point, but he was still stubborn. In the end, the people made the things and really said that.

Doesn’t that mean you are ignorant?

"Because the area is reduced, the consumption requirements required are also reduced exponentially. And..." Long Er continued to explain: "Just just windmills can turn, and watermills can run as long as there is flowing water, most of the mechanisms in the city can operate and design by relying on the power of nature, and the actual consumption is much smaller than expected."

Taking nature as the driving force is exactly the bug in the city of Machinery.

According to the records of the Mechanic City in the "Mo Jing", the city was built against the mountains, using steep cliffs and Mechanics as defensive weapons.

By using the wind, water and sunshine of nature to meet all the city's operation needs, it can be self-sustaining for hundreds of years.

But the city of Long Er is different.

The Wind Kingdom has no place suitable for establishing the Mechanism City at all. The supernatural existence of ninja also makes the defense of the Mechanism City less reliable.

It is even worse than the natural barrier of Sand Hidden Village.

If Long Er had completely built the city of the mechanism in the "Mo Jing" records, it would have no meaning at all.

So, he made changes.

Based on the theory of the mechanism city in the "Mo Jing", the alchemy recorded in "Goddes and Dragons" as auxiliary, combined with many machinery and extraordinary techniques from other worlds, the final design plan was designed.

Such a city is completely different from the original government city, and it cannot rely solely on nature as energy consumption.

"In fact, although tailed beasts can be used as energy, I am not ready to use tailed beasts as power source." Long Er continued: "No matter how everyone thinks of tailed beasts, they all have their own consciousness and thinking, and are intelligent creatures equal to humans. I can talk to Shouhe quite well, so how can I bear to use them as batteries?"

"Can't bear it?"

Everyone present couldn't help but want to laugh.

Someone ran to Fengying's office at the age of eight and asked to study the tailed beast chakra, and then went to the prison to find Shohe every now and then (people in the Sand Village called Fenfu Shohe directly, and forgot his real name). The guy who wanted the chakra to store it in the scroll was so embarrassed that he couldn't bear to use the tailed beast as a battery.

They really pointed at Long Er's nose and shouted: I've never seen such a shameless person.

However, when we talk about the serious matter at this time, everyone did not expose this.

The third generation Fengying asked: "But if the last number is not used as energy, then what will your agency city rely on as power?"

"I thought about this when I had the idea of ​​designing a government agency city." Long Er took out two scrolls and spread them on the table.

This is a recording scroll, which contains a lot of information.

"Greer's Stone, an ore containing a huge chakra, according to historical records, ancient people established it and used this ore to build a huge civilization." Long Er pointed to a scroll and said: "I have been conducting investigations for so many years. That ancient city really exists. The city's energy is Greer's Stone, and just at the border between the Kingdom of Wind and the Kingdom of Sichuan, there is still a Greer's Stone vein below the city.

And, I have found people who know the clues.
