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

Ryuuji held the ground with his right hand, feeling the pulse of the earth, and clenched his fist to punch the ground into a pit the size of a bowl.

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

"The Ring of Ugo is also perfectly integrated into the foundation, and the Philosopher's Stone forms a perfect closed loop of mutual replenishment with the earth and dragon veins."

Ryuuji nodded in satisfaction and stood up, looking at the liaison on the other side.

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

"There were signs of rioting at first, but soon calm returned."

"It seems that there is no problem with the dragon vein, but I am not sure if it has really stabilized or temporarily......" Ryuji pondered for a moment and continued: "Order, if it is not necessary, let people not go close to the three-kilometer range of the dragon vein tower." ”

"Yes."

Watching the herald leave, Ryuuji bowed slightly.

Although with the huge amount of dragon veins, if there is a real riot, the entire Loulan will not be enough to explode.

However, there is a solid foundation of the Ugo Ring underneath, and there are three major gates made of vibranium and Edelman alloy and various precious metals, even if the dragon vein is blown up, it will not make a big splash.

But just in case, it's better not to let people come near to avoid accidents.

"Ryuji ......" Ebizo walked over with a solemn face and continued: "The movement just now is too big, I'm afraid it will attract the peeps of many forces, and the construction of the organ city can't be hidden." ”

"So what?" The corners of Ryuuji's mouth curled slightly, "Now that the ninja villages in the ninja world are either mired in war, or they have lost their qualifications to compete and are recuperating, even if they know that Sand Yin is building a trap city, they don't have time to pay attention to us." ”

"That being said, it's better to be careful." Ebizo's face was worried, "The ninja villages don't have the energy to send troops to intervene right now, but it's still okay to send elite squads to destroy it." ”

Hearing this, Ryuuji also became solemn.

As the saying goes, there are only a thousand days to be a thief, and there is no thousand days to prevent thieves.

There are 5,000 knight puppets in Loulan, and they are not afraid even if they face any of the five major ninja villages.

But the flaw of the puppet is that it is not as flexible as humans, even if Ryuuji places an artificial soul in their body, but because of the mechanical body, they cannot obtain the real sense of a normal creature, and they do not have normal human emotions.

In addition, they have no biological structures such as brains, and their intelligence is very simple, and they can only follow orders.

If they fight and kill the enemy, they are undoubtedly a terrible weapon of killing.

But if it is used to prevent the infiltration and sabotage of elite masters, it is not enough.

Until now, the third ninja world war has been underway, and each ninja village wants to be the final winner.

If they find out that Sand Hidden Village is building an invincible war fortress, they will definitely do everything they can to stop it.

Not to mention the other four ninja villages, even the masters of those small and medium-sized ninja villages can't guard against it.

If the entire ninja world is aimed at them, it will be really difficult for the city to be built smoothly.

“…… The next step is to complete the flight system first, let the foundation fly, and we will complete the subsequent construction in the sky. ”

After a little contemplation, Ryuuji offered his opinion.

"The Book of Roje El" did not mention that there would be such a big movement after the successful construction of the Ring of Ugo, so this incident also caught him off guard, and he could only think of this method for the time being.

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

As long as the foundation flies, basically no one can disturb them to build the city.

However, in this way, transportation costs will increase, and the optimal construction sequence will be disrupted, and unnecessary materials and processes will be wasted.

According to the size of the Organ City, this loss is almost worth the harvest of this rain country.

"I think it's better for the village to send someone to guard here." Ebizo thought carefully for a while and said, "If you build the flight system first, the wasted money will be enough for the village to win a big battle, and it is better to let the ninjas of the village idle for a year." ”

"But there are risks associated with that." Ryuuji shook his head slightly, "It's good if you can keep the enemy out perfectly, if not, what's the use of defeating the enemy in the end, the damage caused by the battle will still hinder the construction of the city, and the losses will not necessarily be less than I said." ”

Ebizo still feels that it is a bit of a loss to do the flight system first, but after all, the Organ City was designed by Ryuuji, and the other party knows the Organ City better than himself.

Moreover, the ability of the other party is also obvious to all, and their own ideas are not necessarily more correct than the other party.

So, after hesitating for a moment, he still agreed with Ryuuji's point of view.

“…… Then do as you say! ”

"I'll adjust the factory equipment first, make the relevant equipment parts first, and leave the surrounding defense work to you, and let the outside world get the news one day later, and the possibility of the success of the construction of the organ city will be greater."

"I'll do my best."

……

After bidding farewell to Ebizo, Ryuuji went to the Loulan underground factory.

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

But since obtaining the "Golden Elf Technique", it has become three.

The first is based on the ninjutsu engraving of the ultra-light and heavy rock technique and the super heavy rock technique, creating a proportional system that can freely adjust the density of the city.

The second is a planetary engine created by combining the alchemy of Golem and Dragon with the technopunk technology of Age of Steam.

Ahem, this thing is a black technology created by combining two different systems of Dragon Er, and the power naturally cannot reach the point of pushing the planet.

Not even pushing the mainland or even small cities.

After all, the worlds of "Golem and Dragon" and "Steam Age" are not worlds with power systems against the sky, and it is impossible to combine their technology to transform things against the sky.

But with a ninjutsu technology system that changes the density of objects, the city can fly.

But this is a big problem for energy consumption, and without the infinite energy of the dragon vein, it is difficult to fly in the sky all the time.

The third is the floating island technology recorded in the Book of Golden Elves.

It was a floating system made with anti-gravity technology as the core.

Continents can be floated with tiny energy consumption.

Ryuuji hadn't had time to learn much about this book since he got it, but he had already read too much about the Otherworld.

Although most of them come from different worlds, many worlds have the same power system.

In particular, magic technology that uses magic as an energy source.

Because the nature of magic is similar to that of chakra, the magic of most magical worlds comes from life and spirit, except for a few worlds with mysterious roots such as the Moon-like Moon.

And what magic can do, Chakra can almost do, but the formula is different.

Therefore, although I don't have much in-depth understanding of the "Book of Golden Fairies", I basically understand the principles and methods of making the anti-gravity system recorded in this book.

"First make the parts and materials of the first two flight systems, and use 3D printers to do what ordinary equipment can't do, and by the way, learn more about the floating island system, and transform its formula model into a chakra method." Ryuuji was making plans while quickly transforming the factory equipment.

He still has so many research projects on his hands that he has all sorts of mundane things to do, and he has to get the work done here as soon as possible and get all the stuff done.

With the help of a working golem, the speed is countless times faster than when it was first transformed.

It took him only six hours to rebuild the equipment and then let the working puppets do the production.

And he himself went headfirst into the studio of the portable space.

The materials for the specific gravity system (a system that changes the density of matter) and the planetary engine have long been prepared, and all kinds of materials and equipment have been prepared for a long time, so it is enough to enter the data into the 3D printer, put the corresponding materials into it, and then wait patiently for the manufacturing to be completed.

Both of these things are big guys......

Substance Specific Gravity System...... To meet the power of covering an area of 50 square kilometers, it is necessary to build at least an area of 1.5 square kilometers.

The planetary engine, on the other hand, consists of numerous jets, one of which is installed almost every kilometer under the foundation.

Even if most of the parts can be produced by ordinary machinery and equipment, it is not a small project.

During the manufacture of the parts, the formula conversion experiments of the anti-gravity levitation device were carried out.

……

Little by little, time passed.

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

Day 2.

Ryuuji came out to direct the working puppet to assemble the produced parts, and then continued to return to the studio to study.

Day 3.

A team of wandering ninjas from the country of flowers came to the neighborhood to investigate the situation, and were killed by Ebizo, who had been prepared for a long time.

And Ryuuji is the same as yesterday.

Fourth, fifth, and sixth days......

The spies from the various ninja villages came to Loulan one after another.

Most of them were killed by the prepared Ebizo people, but there are still guys who are good at hiding and infiltrating that haven't been discovered, and there are guys who have escaped with good escape methods.

There are also powerful masters among these spies, and some of them are awesome, and even Ebizo is a little difficult to deal with.

But after the dense puppet army that could continue to be reborn rushed out, no matter how powerful the master was, he was finally submerged under the puppet army.

And Ryuuji is still living the days he had a few days ago.

Day 7, Day 8, Day 9, Day 10......

There are more and more teams that come to inquire about intelligence, and the number of misses in Ebizo is also increasing, and gradually, more and more forces know what Sand is secretly building.

But.

Although they didn't know exactly what Sha Yin was building, such a secret and huge project would definitely not be good for them.

At the time of the Ninja World War, everyone wanted to be the final winner.

At this time, seeing Sha Yin secretly making big moves, he naturally didn't want him to succeed.

So, with the intentions of some people, the news was spread more and more widely, and all kinds of rumors flew up.

Among them, the most widely rumored and most widely rumored is that Sand Hidden is secretly making weapons to dominate the ninja world.

Both Ebizo and Sagakure are worried.

But Ryuuji turned a blind eye to all of this and worked as usual every day.
