This puppeteer is a bit... well...

Chapter 23 Grell's Stone

"It can fly!?"

Everyone in the room stared wide-eyed, looking incredulous.

The Third Kazekage took a deep breath and tentatively asked, "When you say you can fly, do you mean the entire city?"

"That's right."

"That's impossible!"

Upon receiving a clear answer, Chiyo exclaimed as if she had heard something utterly absurd, "Do you know how big our Sunagakure is?"

"Since I've designed the city, I'll naturally investigate the relevant data," Ryuji shrugged. "It's probably over three thousand square kilometers!"

What does 30 square kilometers mean?

It's about half the size of Shanghai.

Yes, you heard that right.

Sunagakure, though only a small ninja village in terms of size, is actually about half the size of Shanghai.

The Ninja Village... Although it is named after a village, it is actually the size of a city in terms of both population and land area.

The largest village in the ninja world, Konoha, is almost as big as Shanghai. In such a large city, someone might tell you they can fly.

Do you believe it?

Chiyo, anyway, didn't believe it.

No, none of you here believe that.

"Since you know the city is so big, how dare you say it can fly?" Chiyo stood up and questioned, "Mechanical engineering... to put it bluntly, it's just a technology that saves manpower and accomplishes great things with small tools."

But even the smallest things need a source to trigger them; the bigger the thing, the larger the source it needs to be.

Windmills need wind to blow, waterwheels rely on the flow of water... What are you trying to do to make your city fly?

Tailed beasts?

That probably isn't enough!

"No, the tailed beasts' chakra is more than enough." Ryuji sat up straight and explained with a smile, "When I designed the mechanical city, I took spatial science into account. The city is shaped like a ring of mountains, and it is divided into residential areas, military areas, administrative areas, commercial areas, agricultural areas, industrial areas, garbage disposal areas, etc., from low to high. Although the overall area has shrunk by more than a thousand square kilometers, the living space for people has actually increased. It will be enough even if the population doubles in the future."

"This... I don't quite understand," the Third Kazekage asked doubtfully. "The total area has shrunk by two-thirds, so why is the living space larger? What does this spatial science mean?"

Upon hearing this, the others also looked over.

Not only did the Third Kazekage not understand, but they were also completely confused.

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

"Spatial science is a set of real-world laws that I have summarized. Just like your room, if you put furniture randomly, the room will become messy and take up less space. But if it is arranged in a regular and orderly manner, it will free up a lot of extra space. I call this phenomenon spatial science."

Ah! That's it?

Everyone was a little confused.

They had previously heard Ryuji talk about spatial science and assumed it was some kind of high-level theoretical knowledge, like spatial ninjutsu.

The result is simply a common phenomenon in daily life.

At the same time, they also had doubts.

"Even with the most reasonable planning, freeing up two-thirds of the space is too much. I often tidy up my house, but I've never had so much free space before."

"How big is your house? How big is a city? Have you ever used a formula to make the most scientific space allocation?" Ryuji rolled his eyes and interrupted Chiyo, who was about to say something, with a hint of annoyance. He said, "In short, there is no need to question this. Those who know, know. Those who don't, it's a waste of time to say anything. The blueprints are all here. Take a closer look and savor them."

Upon hearing this, Chiyo immediately shut her mouth.

Even after the other party had put it so clearly, I still argued back. In the end, they actually made the product, and it really was exactly as they had described.

Wouldn't that just show that I'm ignorant?

"Because the area is smaller, the required energy consumption is also reduced by a factor of two. And..." Ryuji continued to explain, "Just like a windmill only needs wind to turn and a waterwheel only needs flowing water to operate, most of the mechanisms in the city are designed to operate using natural forces, so the actual energy consumption is much less than you might imagine."

The fact that nature is the driving force behind the mechanical city is precisely its bug.

According to the records of the Mechanical City in the Mo Jing, this city was built against the mountain and used steep cliffs and mechanical devices as defensive weapons.

By utilizing the wind, water, and sunlight of nature to meet all the city's operational needs, it can remain self-sufficient for hundreds of years.

But Long Er's mechanical city is different.

The Land of Wind simply doesn't have a suitable place to build a mechanical castle. The supernatural existence of ninjas also makes the defenses of a mechanical castle less reliable.

It's not even as good as the natural barrier of Sunagakure.

If Long Er were to build the mechanical city exactly as described in the Mo Jing, it would be meaningless.

So he made changes.

Based on the theory of mechanical cities in the Mo Jing, and aided by the alchemy recorded in Golems and Dragons, and combined with many otherworldly machines and extraordinary technologies, the final design was created.

This kind of city is completely different from the original city of government offices, and it cannot rely solely on nature as its energy source.

"In fact, while the Tailed Beasts are perfectly adequate as an energy source, I haven't planned to use them as a power source," Ryuji continued. "Regardless of how people view the Tailed Beasts, they have their own consciousness and thoughts; they are intelligent beings equal to humans. I get along quite well with Shukaku, so how could I bear to use them as batteries?"

"Can't bear to?"

Everyone present couldn't help but laugh.

This guy, who ran to the Kazekage's office at the age of eight to request research on the Tailed Beasts' chakra, and then went to the prison every few days to ask Shukaku (the people of Sunagakure just call him Bunpuku Shukaku, forgetting his real name) for chakra to store in a scroll, actually has the nerve to say here that he can't bear to use the Tailed Beasts as batteries.

They really pointed at Ryuji's nose and shouted: "I've never seen such a shameless person!"

However, when the conversation turned to serious matters, no one exposed this fact.

The Third Kazekage asked, "But if you don't use the last digit as an energy source, what will power your mechanical castle?"

"I thought about this problem when I first had the idea of ​​designing the mechanical city." Ryuji took out two scrolls and spread them out on the table.

This is a record scroll, densely covered with a lot of information.

"Grell Stone, a mineral containing a vast amount of chakra. According to historical records, ancient people used this mineral to build a great civilization." Ryuji pointed to a scroll and said, "I have been investigating for many years. That ancient city really exists. The city's energy source is Grell Stone, and it is located on the border between the Land of Wind and the Land of Rivers. There is also a Grell Stone vein beneath the city."

Furthermore, I have found someone who knows the relevant clues.

If we find that guy, we might find a mineral vein.

Thank you Tian Shang 'Dream' for the generous donation, thank you very much.

Also, the next chapter will be added tomorrow.

After two consecutive all-nighters, I couldn't take it anymore and went to sleep.
