The research room is incredibly quiet.

Against a white background.

On the contrary, there is a lot less industrial atmosphere here.

Bai Yu looked around, looking at the sophisticated mechanical instruments around him, and could probably guess what was happening here.

Uzumaki Chiharu came to Bai Yu's side, picked up a sword of Thor, and said with emotion:

"My lord, according to the coordinates specified by the Sand Hidden before you left Konoha, we have discovered the raw materials for the manufacture of the Thor's Sword, which is what you call the Extraterrestrial Meteorite."

Bai Yu was pleasantly surprised: "Yes, as we guessed, the Sand Hidden Desert contains this kind of wealth that no one else can discover. ”

"We searched for them and unearthed them with special instruments." Chiharu Uzumaki said excitedly: "After that, based on the first Thor's sword, we started to create this weapon that can store the energy of the specified chakra, so we succeeded halfway, of course, this is also a success." ”

"Uh, half?" Bai Yu suddenly looked puzzled.

Chiharu Uzumaki was slightly embarrassed, and used her chakra as an introduction to inject the jet-black hilt of the Sword of Thor that she had just picked up.

Instantly.

The Thunder God Sword in her hand was the same as Bai Yu's energy long sword that Bai Yu summoned for the first time, and the sword blade composed of extreme arcs of extreme arcs burned under the hilt.

Zizka –

The Sword of Thor is surrounded by a strong electric current.

But as the chakra injected by Uzumaki Chiharu gradually weakened, the yellow blade of the energy long sword in Bai Yu's eyes that seemed to be sharpened like iron and mud also weakened.

Eventually, something that seemed to be the core in the middle of the hilt of the sword could not withstand the impact of energy and finally cracked.

Chiharu Uzumaki embarrassedly explained:

"Because the Sword of Thor, invented and manufactured by the second generation Hokage, the core is made of a special meteorite that has been tempered."

"If the meteorite ore we excavated is used to make the Sword of Thor, it cannot be refined and reused, so the only materials we have can only take the lead in creating a batch of disposable Thor's Sword."

After hearing this, the corners of Bai Yu's mouth twitched, and he picked up the black and heavy hilt of the Thor Sword from the assembly line, and after weighing it, he smiled softly and bitterly:

"Thor's Sword Youth Mini Edition, the ninjas' first energy weapon?"

Come to think of it.

Bai Yumeng shook his head, and then put the hilt of the Sword of Thor back on the assembly line, looked at the black hilt that was still redundant in the inventory, and asked calmly:

"Elder Chiharu, how many of these disposable weapons do we have now?"

Chiharu Uzumaki came to the front of a machine and explained with a smile, "By the way, my lord, I forgot to tell you that these machines for forging the Sword of Thor were all purchased from the Land of Iron and cost a lot of money. ”

Bai Yu nodded, and did not speak, if science and technology want to progress, burning money is the lowest guarantee.

The forging technology of the Iron Country is indeed one of the best in the ninja world.

Seeing that Bai Yu had no objection to this huge expense, Chiharu Uzumaki pulled out an important scroll from the pile of scrolls next to the machine.

After taking a closer look, she responded:

"My lord, after all these years, we have consumed the extraterrestrial meteorite mines we found in the Sand Hidden Desert, and developed a total of 1,214 one-time Thor's swords, as well as 10 permanent Thor's swords."

Bai Yu raised his eyebrows and asked in surprise, "If you want to create a reusable energy weapon, do you need so much iron meteorite?" ”

Chiharu Uzumaki sighed: "Yes, and many of the iron meteorites we mined from the Great Sand Hidden Desert are unusable, only a few specific ones can be used, and they seem to have a strange connection to Chakra. ”

said.

Chiharu Uzumaki took out a strangely shaped iron meteor from the mechanical equipment.

This metallic hue has a strange dark gold state, as if it has been baptized by some kind of energy.

Bai Yu took the diamond-shaped iron meteor from the hand of Uzumaki Chiharu, and seriously played with the iron meteor that felt cold in his hand, and indeed sensed the chakra energy in his body.

First of all, Bai Yu can confirm with a chakra scan that it does not have any signs of metal or chemical radiation, and it only has a strange metallic cold feel in the palm of his hand.

"This thing does have a connection to Chakra."

Bai Yu sensed that he fell into deep thought, and immediately guessed that there was a possibility.

Bai Yu handed the Iron Fall to Chiharu, and his eyes were projected to the Sword of Thor on the assembly line, and he guessed in his heart, is there a possibility that this is the Iron Fall who has been in contact with the big barrel wood?

When Otsuki arrived in the ninja world from outer space, due to his own gravity, his own chakra baptized a lot of iron meteors, causing strange changes in the internal substance.

Then these iron falls follow the big barrel wood and fall to the ninja world together.

This possibility is not ruled out.

A long time ago, Otsuki descended to the ninja world and planted a sacred tree......

"My lord, what do you think this weapon should be used in?"

Chiharu Uzumaki asked earnestly.

Bai Yu immediately responded:

"Distribute all of them to the core combat power of Ninja Village, and continue to mine that weird iron meteorite, no matter how much it is mined, all of them will be made into permanent energy weapons, and the production of disposable weapons will be reduced."

Uzumaki Chiharu nodded seriously, and said with a little worry: "I'm worried that the Uchiha Ninja Village doesn't have many of these iron meteorites in the Great Desert of the Sand Hide. ”

Bai Yu suddenly smiled and said:

"Don't worry, Juan and Ye Cang are very familiar with Shayin, they know how many potholes similar to iron meteorites there are in the Shayin Desert, as for Shayin's side, I will find a way to solve it, and I will give you the exact news in the next few days."

"Really?" Uzumaki Chiharu suddenly admired it in her heart, and although she was a little surprised, she quickly nodded.

Again, she felt.

It was an incomparably correct choice to be persuaded by her granddaughter to lead the Uzumaki remnants to join the Uchiha Ninja Village.

From Bai Yu's conversation, Chiharu Uzumaki can be 100% sure.

The boy with short dark red hair in front of him can almost play with the relationship between the five ninja villages in the ninja world at will.

Looking at the ninja world, who can have this kind of courage?

Bai Yu replied with a smile: "Well, oh, by the way, when this time is over, I can try to treat your granddaughter's Xiao Qianna's injury." ”

He has never been useful since he entered lv6 in medical ninjutsu and obtained the "Creation and Regeneration Technique", one of Tsunade-hime's core medical skills.

This ability to regenerate flesh and blood.

Bai Yu if developed properly.

He thought that he should be able to cure Xiao Qianna's vocal cord disease.

Chiharu Uzumaki was suddenly overjoyed and said excitedly: "Thank you, thank you, your lord, if you can cure Qianna...... I...... I ......"

Chiharu Uzumaki was so excited that her voice choked, and she didn't know what words to use to describe her gratitude to Bai Yu at the moment.

Bai Yu shook his head and smiled: "You just need to be in the Uchiha Ninja Village and complete your duties, and also, the black rod I asked Sha Yin to send back before, do you have any research results?" ”

Chiharu Uzumaki shook her head and said, "I don't have a clue at all, those substances don't exist in the ninja world just like the Extraterrestrial Iron Meteor we mined. ”

Bai Yu stretched out his hand and rubbed his chin, nodded and said, "I know, after a while, I will introduce you to a ninja who has achieved something in scientific research." ”

Uzumaki Chiharu's expression froze, and he suddenly asked, "Is it Orochimaru, one of the three ninjas?" ”

The corners of Bai Yu's mouth twitched again, and he said with some embarrassment: "Can you guess this?" ”

"Hahaha!" Chiharu Uzumaki smiled and said, "After all, you sent back a lot of Orochimaru's research projects before, by the way, you come with me again." ”

"Hmm." After Bai Yu bowed his head, following behind Chiharu Uzumaki, he knew that this old man who was temporarily in charge of the Uchiha research project would definitely have a surprise for him.

The two of them walked through the technology research area with a pure white background, and entered a room with an ordinary background that seemed to be full of divine sacrifices.

Bai Yu soon discovered that what seemed to be the sacrificial platform here was filled with dense transparent containers, and the containers contained a pair of writing wheel eyes that had been sealed by the puppet technique.

Bai Yu was surprised: "The remote puppet sealing technique I conceived before...... It worked? ”

Before he left the Uchiha, he had imagined that the core seal of those Uchiha puppet ninjas in the ninja village would be distinguished from the puppets through a special sealing technique, that is, to reach the brain in the tank and remotely control the puppet body.

Even if the puppet is destroyed, as long as the spiritual power of the sealed chakra eye does not disappear, the manipulable puppet can be created again.

Chiharu Uzumaki turns on the lights on this house.

The light shines.

Bai Yu discovered that the platform where the seal writing wheel eye was placed was a traditional Uchiha altar, which had a simple and strange appearance, and seemed to contain mysterious powers.

Chiharu Uzumaki explained, "Yes, based on your previous conjectures, plus the improvement of our Uzumaki Clan's sealing technique, we have developed a sealing technique that distinguishes the core energy seal from the puppet, and applied it to the Uchiha puppet ninja. ”

Bai Yu gasped.

This sealing.

If the scorpion knew about it, the scorpion would definitely pursue it frantically, although it seems that only the ninjas of the Uchiha clan can use it.

"The current group of puppet warriors of the Uchiha clan, with the blessing of various sealing ninjutsu, as long as the chakra stored is enough, and these core seal writing wheel eye containers are not destroyed, they are equivalent to having eternal life."

Chiharu Uzumaki said, with some envy in her voice.

She didn't write the wheel eye herself.

Even the Vortex people don't have this kind of item that can be crafted into a special energy core, so they can't experience the feeling of having eternal life.

Of course, this kind of eternal life is the most painful torture for those who do not want to live forever.

It doesn't have any tactile sensations.

It's like a free consciousness in captivity.

You can only rely on the puppet to act, and if you get out of the puppet, you are just a pair of eyes that have the consciousness of the host, which is not miserable.

Bai Yu was pleased: "This is the reward they deserve, and if this development continues, the ninja world will usher in a new pattern in the future." ”

Thinking about it, the corners of Bai Yu's mouth rose slightly, Kaguya created Bai Jue through the Divine Tree to protect himself and resist external risks, and he Bai Yu can now use the Uchiha clan to turn the ninjas who died in battle into puppets with the same combat power as before he was alive.

The more time passes.

In the future, the Uchiha will have an army of immortal puppets, and at that time, as long as he has enough chakra energy, the Uchiha will be able to easily complete the hope of dominating the ninja world.

When Bai Yu thought of this, he couldn't help but sigh that Madara's long-cherished wish would actually come true in his own hands.

I don't know how Madara, who betrayed each other with the Uchiha at the beginning, will feel when he sees this Uchiha and become the only overlord in the ninja world.

Could it be the same as Tuanzang who didn't kill Bai Yu when Bai Yu was weak, and now he can only plant the seeds of regret in his heart.

In addition, the immortality pursued by the big barrel wood also appeared in such a branch bloodline family.

Seeing that her adult was deep in thought, Uzumaki Chiharu didn't bother him deliberately.

If it weren't for this genius boy.

Give her Chiharu Uzumaki a hundred brains, and she can't think of such a project, let alone try to study it.

Of course.

Bai Yu also made a mistake and opened up such a strange path for the Uchiha.

He was looking forward to the scene in the future when the Uchiha's immortal puppet army, which was numerous, would go to war with the white army, which was mainly based on numbers.

"Elder Chiharu Uzumaki, I have recently tried to cooperate with the Sand Hide, and a group of skilled Sand Hide puppet makers will come back, and at that time, please make sure to make a puppet body suitable for Uchiha puppet ninja warriors."

Bai Yu said, immediately thought about it, and said seriously:

"Of course, I will also find a way to find a strong person who designs an outstanding puppet body, and design the best puppet body for the puppet ninja of Uchiha Ninja Village."

Uzumaki Chiharu's eyes also contained expectations, if the Sword of Thor could only temporarily enhance the combat power of the Uchiha Ninja Village, then these immortal Uchiha puppet ninjas were the core strength of Uchiha's future invincible position in the ninja world.

Next.

Led by Chiharu Uzumaki, Bai Yu visited the progress of the rest of the research projects.

Tonight can be described as full of surprises, and the several research projects that Bai Yu is optimistic about getting from Orochimaru have made good substantial progress.

The most surprising thing.

It was still the Uchiha puppet ninja who broke through the distinction between the puppet and the core seal, but Uzumaki Chiharu also explained the disadvantage of the current Uchiha puppet, that is, the scope of the spiritual seal to control the puppet has strict control.

Chakra enough case.

A puppet ninja's core seal, which can control a puppet body and move within a radius of 1 km.

As for the chakra energy, it can be absorbed by Bai Yu according to the technology left by the scorpion and the special items he invented to store chakra, which is equivalent to a battery.

1 km, it is not far away, and it is not close to it.

But in terms of the ninja's foot strength.

It's only a few minutes away.

On the way home, Bai Yu added the problem of puppet ninja endurance to the list of problems to be solved in the future, but what needs to be solved now is the problem left over from the aftermath of this war.

It was overcast.

The air is humid.

The war that has just ended has made many people feel depressed.

Bai Yu walked on the main Uchiha road, looking up at the sky, he didn't intend to use the Rain Tiger Freedom Technique to disperse the rain clouds around him.

The Uchiha, who has just experienced a great war, needs a heavy rain to wash away the entire ninja village, wash away misfortune and bad luck, and welcome the sunny days in the near future.

Bai Yu's thoughts were chaotic, he looked at the brightly lit neighborhood, and began to sort out his thoughts.

I've been caught......

This has become the confidence to fulfill the promise he just made to Elder Chiharu, and the information scroll of the sand is a clear signal for help.

Now that Sand Hide is in the entire ninja world, it is estimated that he can only be cheeky to rescue Yu Uchiha Ninja Village.

After all, not long ago, Bai Yu deliberately asked Ye Cang to contact Sha Yin again to negotiate the mining of iron meteorite.

"I'm Ailuo, I'm definitely going to save it."

Bai Yu whispered:

"Otherwise, the Xiao organization's side has already collected 3 tailed beasts, and it is absolutely impossible to let Obito and Nagato collect tailed beasts, collecting them so easily, even if they have successfully captured my Airo now."
