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

Chapter 122 Building a City in the Sky

"The ground is very solid, and you can feel the pulse of life."

Ryuji placed his right hand on the ground, feeling the pulse of the earth, and punched a hole the size of a bowl into the ground.

Then, the crater healed at a speed visible to the naked eye.

"The Ring of Ugo is also perfectly integrated into the foundation, and the Philosopher's Stone, the earth, and the dragon veins form a perfect closed loop that mutually replenishes each other."

Long Er nodded in satisfaction, stood up, and looked at the liaison officer on the other side.

"How's the situation on the dragon vein side?"

"There were signs of rioting at first, but it quickly subsided."

"It seems the dragon vein is fine, but it's uncertain whether it's truly stabilized or just temporarily stable..." Long Er pondered for a moment, then continued, "Give the order that unless absolutely necessary, people should not approach the area within three kilometers of the dragon vein tower."

"Yes."

Watching the messenger leave, Long Er nodded slightly.

Even with the sheer size of the dragon vein, if it were to truly erupt, the entire Loulan region wouldn't be enough to withstand the explosion.

However, with the stable foundation of the Ring of Ugo below and the triple gates made of vibranium, adamantium, and various precious metals above, even if the dragon vein were to explode, it wouldn't cause much of a ripple.

However, just to be on the safe side, it's best to keep people away from the area to avoid any accidents.

"Ryuji..." Ebizo walked over with a solemn expression and continued, "The commotion just now was too great. It will probably attract the attention of many forces. The construction of the Mechanized City can no longer be kept secret."

"So what?" Ryuji's lips curled up slightly. "Right now, the various ninja villages in the ninja world are either mired in war or have lost their chance to compete and are recuperating. Even if they know that Sunagakure is building the mechanical castle, they don't have time to pay attention to us."

"That being said, it's still best to be careful." Ebizo looked worried. "Right now, none of the ninja villages have the resources to send troops to intervene, but they can still send elite squads to cause trouble."

Upon hearing this, Long Er also became serious.

As the saying goes, you can only be a thief for a thousand days, but you can't guard against thieves for a thousand days.

Loulan has five thousand knight puppets, so they are not afraid of any of the five great ninja villages.

However, the puppets' weakness is that they are not as flexible and adaptable as humans. Even though Ryuji implanted artificial souls in them, due to their mechanical bodies, they could not obtain the sense of reality of normal living beings, and therefore did not have normal human emotions.

In addition, lacking biological structures such as a brain, their intelligence is also very simple, and they can only follow orders.

If it were a war to kill the enemy, they would undoubtedly be terrifying killing machines.

However, it is not enough to prevent elite experts from infiltrating and sabotaging.

As the Third Shinobi World War progresses, each ninja village wants to be the final winner.

If they discover that Sunagakure is building an invincible war fortress, they will do everything they can to stop it.

Not to mention the other four major ninja villages, even the experts from the smaller ninja villages are hard to defend against.

If the entire ninja world were to target Sunagakure, then the construction of the mechanical castle would be very difficult.

"...The next step is to complete the flight system so that the ground base can take flight, and we can complete the subsequent construction in the air."

After a moment's thought, Ryuji offered his opinion.

The Book of Rozier did not mention that the successful creation of the Ring of Ugo would cause such a great commotion, so this matter caught him off guard, and this was the only solution he could think of for the time being.

Although there are people in the ninja world who can fly, there are only a very small number, in the single digits.

Once the foundation is airborne, virtually no one can disturb their city-building efforts.

However, this would not only increase transportation costs, but also disrupt the optimal construction sequence and waste unnecessary materials and procedures.

Considering the size of the city, this loss is almost equal to the harvest of the Rain Kingdom.

"I think it's better to have the village send people to guard this place," Ebizo said after thinking for a while. "If we build the flight system first, the money wasted would be enough for the village to win a major battle. It's more worthwhile to let the village's ninjas stay idle for a year."

"But there are risks involved." Ryuji shook his head slightly. "If we can perfectly keep the enemy out, that's fine. But if we can't, what's the point of defeating them in the end? The damage caused by the battle will still hinder the city's construction, and the losses might not be less than what I'm saying."

Ebizo still felt it was a waste to develop the flight system first, but after all, the Mechanical Castle was designed by Ryuji, who knew it better than he did.

Moreover, the other party's abilities are obvious to all, and one's own ideas are not necessarily more correct than the other party's.

So, after a moment's hesitation, I agreed with Ryuji's point of view.

"...Then let's do it your way!"

"I'll go adjust the factory equipment first and make the relevant parts. I'll leave the surrounding defenses to you. The longer we wait until the outside world gets the news, the greater the chance of the mechanical city being successfully built."

"I will definitely do my best."

……

After bidding farewell to Ebizo, Ryuji headed to the Loulan underground factory.

The flight system of the mechanical city was originally a combination of two technologies.

However, since obtaining the "Golden Fairy Technique," it has become three types.

The first type is based on the ninjutsu imprints of the Ultra-Lightweight Rock Technique and the Ultra-Heavyweight Rock Technique, creating a gravity system that can freely adjust the density of a city.

The second type is a planetary engine created by combining the alchemy of "Golems and Dragons" with the mechanical punk technology of "Steam Age".

Ahem, this thing is a black technology created by Ryuji by combining two different systems, so its power is naturally not enough to propel a planet.

It's not even feasible to promote it in mainland China or smaller cities.

After all, neither the worlds of "Golems and Dragons" nor "Steam Age" are worlds with overpowered power systems, and the things created by combining their technologies are unlikely to be overpowered either.

However, when combined with a ninja technology system that alters the density and weight of objects, the city can be made to fly.

However, this poses a significant problem for energy consumption. Without the infinite energy source of the Dragon Vein, it would be difficult to keep flying in the sky.

The third type is the floating island technology recorded in the "Book of the Golden Fairy".

It is a floating system manufactured using anti-gravity technology as its core.

It is possible to make the continent float with minimal energy consumption.

Since obtaining the book, Ryuji hasn't had time to learn much about it, but he has already become familiar with a great deal of knowledge about other worlds.

Although most of them come from different worlds, the power systems in many of these worlds are the same.

Especially magical technology that uses magic as its energy source.

Because the nature of magic is similar to that of chakra, apart from a few worlds like Type-Moon where the magic originates from a mysterious source, most magical worlds derive their magic from life and spirit.

What magic can do, chakra can do almost too, only the formulas are different.

Therefore, although I don't have a deep understanding of "The Book of the Golden Fairy", I have a basic understanding of the principles and methods of making the anti-gravity system recorded in the book.

"First, produce the parts and materials for the first two flight systems. Use a 3D printer for parts that can't be made with regular equipment. Also, take the opportunity to learn more about the floating island system and convert its formula into a chakra-based system." Ryuji made plans while rapidly modifying the factory equipment.

He still has too many research projects to do and all sorts of mundane matters to attend to. He must finish his work here as soon as possible and then get all the backlogged stuff sorted out.

With the help of the working puppets, the speed is many times faster than during the first modification.

He completed the equipment modification in just six hours and then put the work puppets into production.

He then plunged into his portable studio.

The data for the material density system (the system that changes the density of a material) and the planetary engine have already been prepared, and all kinds of materials and equipment have been ready. So all we have to do is input the data into the 3D printer, put in the corresponding materials, and then patiently wait for the manufacturing to be completed.

Both of these are huge...

The material density system... to meet the power requirements of covering an area of ​​fifty square kilometers, it must be built to cover an area of ​​at least 1.5 square kilometers.

The planetary engine is composed of countless jet devices, with one installed almost every kilometer below the ground.

Even if most of the parts can be produced using ordinary machinery, it is still not a small project.

During the manufacturing of the parts, experiments on the formula conversion of the anti-gravity levitation device began.

……

Time passes little by little.

That night, various equipment parts were produced in an orderly manner.

Day two.

After Ryuji came out and directed the work puppets to assemble the produced parts, he returned to the workshop to continue his research.

Day three.

A group of wandering ninjas from the Land of Flowers came to the vicinity to investigate the situation, but were killed by Ebizo, who was prepared.

Long Er, on the other hand, did the same thing as yesterday.

The fourth day, the fifth day, the sixth day...

Spy envoys from various ninja villages arrived in Loulan one after another.

Most of them were killed by Ebizo's men who were prepared, but some skilled in stealth and infiltration remained undetected, while others with excellent escape techniques managed to get away.

Among these spies are some formidable experts, some of whom are so skilled that even Ebizo has some trouble dealing with them.

But as the densely packed, ever-regenerating puppet army surged forth, even the most skilled warriors were eventually overwhelmed by it.

Ryuji continued living the same life as he had the previous few days.

The seventh day, the eighth day, the ninth day, the tenth day...

More and more teams came to gather intelligence, and Ebizo failed more and more often. Gradually, more and more forces learned what Sunagakure was secretly building.

but.

Although they didn't know exactly what Sunagakure was building, such a secretive and massive project was definitely not a good thing for them.

Now that the Ninja World War has progressed to this point, everyone wants to be the final winner.

Seeing that Sunagakure was secretly plotting something big, they naturally didn't want it to succeed.

As a result, thanks to the deliberate actions of some people, the news spread wider and wider, and all sorts of rumors began to circulate.

The most widespread and numerous rumors are that Sunagakure is secretly manufacturing weapons to dominate the ninja world.

Ebizo and everyone in Sunagakure Village are deeply worried about this.

But Long Er ignored all of this and continued to work his daily routine.
