Because he will cooperate with Konoha in the future, Ryuuji is also cautious when extracting materials, for fear of leaving any traces on the other party.

also did a physical examination, blood draw, and laboratory tests while the two were still unconscious, to see how their physique was different from ordinary people.

But after some inspection, I found that it was no different from ordinary people, and I lost interest.

It's just a simple matter of putting away the materials for the two of them, in case they need it in the future, but they don't.

After all this was done, it was already dark.

Ryuuji chatted with Sara, who came to discuss, for a while, and after clarifying his doubts and explaining for a while, he went to rest.

……

Following.

Ryuuji drilled into the production plant early in the morning to modify the production equipment and the dragon vein channel.

He had to make the preparations for the construction of the Organ City before going to Konoha, and when he went to Konoha himself, the people sent by the three generations of Kazekage could continue to do it.

The first is to build an additional equipment for the production of workers' puppets, and secondly, to change the equipment for the production of knight puppets to the equipment for the production of parts and smelting materials for the city.

Due to financial problems, the construction period was much slower than expected, and Ryuuji did not expand the production equipment much.

The main thing is to increase the dragon vein channel.

Ryuuji divides the dragon vein into two large regions, transporting them to equipment needs and golem needs on the other.

Then, according to the area patrolled by the puppets, he divided the area of the future construction of the Organ City into one hundred and thirty waterways.

This is still temporary, and when the city is built, it will be changed, and it will be redistributed through the urban area.

Finally, about the safety of the dragon vein...... In order to prevent the construction of the Organ City, an enemy or spy lurks in the dragon vein to cause chaos, causing the dragon vein to run wild.

Ryuuji designed three spiral levels called "Door of Life and Death" above the dragon vein.

It is a Taiji Gate made of an alloy of secondary Edelman alloy, vibranium and chakra metal and made of helical gear.

It is structured as a two-way door, and it is shaped like a disc that protrudes a little upward, like an enlarged round shield.

The dragon vein chakra can be passed through a filter in the middle of the door that closes automatically.

In addition, each gate has an artificial soul as a recognizer, which will identify itself by itself, and only a puppet containing the soul consciousness of Ryuji can bring people in and out.

Ryuuji is going to dismantle the spiral staircase in and out, and then specialize in producing puppets that can fly and are responsible for picking people in and out.

In this way, hundreds of kilometers in the air is another level.

If the enemy wants to come to the gate of life and death, he must prepare for airborne preparations, and then he can also destroy the three gates by brutal means.

However, the gate, which is made of Edelman metal and vibranium, is a structure based on the shield of Captain America...... At present, no one in the ninja world can break the door violently.

However, before this defense system can be made, a control system must be made to control the output of the dragon vein.

Otherwise, if you run here as soon as there is a problem, it will be easy to create an opportunity for the enemy to sneak in.

Of course, this is also a big project, and one person can't complete it in a short time.

Therefore, Ryuuji prioritizes the equipment for the puppets of production workers.

At that time, use the dragon vein chakra to start work, and create a worker puppet to start work together, which is undoubtedly the most time-saving.

……

Time passed.

At nine o'clock in the evening of the first day, Ryuuji made a production line of the workers' puppets.

The next day, hundreds of worker puppets were produced.

These puppets can fold their bodies 180 degrees, rotate their upper and lower bodies, heads, arms and other joints at 360 degrees, and their forearms and palms can be retracted and replaced with screwdrivers, hammers, and saws...... and other tools.

At the same time, the back also followed the thrusters and could fly.

It can be operated in any environment except underwater.

On the third day, Ryuuji completed the transformation and expansion of production equipment.

On the fourth day, the construction team sent by the three generations of Wind Shadow arrived.

There are more than 300 people in total, including more than 50 puppeteers, and the remaining 250 are also skilled craftsmen in the village.

Leading the team was Ebizo.

As the younger brother of Chiyo's mother-in-law, Ebizo is also a puppet master, proficient in mechanical arts and architecture.

In fact, because of the field of mechanical arts, every puppeteer has attained some level of attainment in architecture.

Perhaps the vision is limited by the times, but the level is by no means worse than that of the professional engineers in the previous life.

After explaining the construction period and construction plan to Ebizo, Ryuuji began to improve the dragon vein channel.

During this time, Ebizo began to communicate with Sara and held a banquet in the evening to celebrate the merger of the people of Loulan into the sand.

During the banquet, I don't know if it was arranged in advance by Ebizo, or if the villagers of Shayin really didn't mind the unexpected visitors joining, and the men at the banquet bottled wine and ate meat with each other, and even single men and women invited each other to dance around the bonfire.

All in all, the atmosphere was harmonious.

Originally, the relationship between the two parties, who could still clearly feel the estrangement, was much closer.

On the fifth day, Ebizo arranged for trusted people to go to other cities and countries to buy materials, while he led the construction team and puppet workers to prepare for the door of life and death.

Sara offered to bring a group of young adults to help.

Participating in the construction together helped the people of Loulan to better integrate into Shayin, and Ryuuji did not refuse, arranged some jobs that they were capable of, and calculated the salary.

On the sixth day, the workers' puppets produced 1,300, but the materials left behind by An Lushan had run out.

Considering the construction period, Ryuuji did not continue to purchase materials for production.

And Ryuuji himself continued to modify the Dragon Vein Channel.

It's a technical job, and it's a bit time-consuming.

On the eleventh day, Ryuuji completed the modification of the Dragon Vein Channel.

One hundred and thirty fairways were aligned with the working machines to be laid out in the future.

On the twelfth day, Ryuuji took the lead in building the Gate of Life and Death.

On the fifteenth day, the men who had gone out to buy materials returned, bringing back large quantities of ore of all kinds.

The renovated metal melting furnace officially started.

On the 17th, the second batch of logistics teams from Shayin Village arrived, bringing a large number of modern construction machines.

Like hanging towers, excavators, and the like.

These things are all Ryuuji asked Red to use a 3D printer to make parts, and then take them outside through scrolls to assemble, and then load them into scrolls for the logistics team to bring over.

With the help of these machines, the construction progress was accelerated several times.

The foundation of the door of life and death has been laid.

Ryuuji asked Ebizo to start digging the foundations with men and machines and a thousand worker puppets in preparation for the official construction of the city.

At the same time, the factory began to produce the first part of the city, the Ring of Ugo.

This is an artifact from the alchemy chapter of the Book of Roger, a parallel Arabian mythological world.

Burying it in the earth can solidify the earth's leylines, so that the earth's qi will never leak out and will be immortal forever.

The effect is to maintain the vitality of the earth, and to maintain its thick and strong characteristics, which will never dry up and break.

Of course, the so-called never leaked, eternal immortality is just a modifier on the book, and how long it can really last depends on the material.

And the material prepared by Ryuuji is the "Philosopher's Stone".
