Zabuza thought this place was incredible, many things were completely different from the Kiri Ninja Village.

Following the other party's guidance, after entering a room, the grass ninja said: "Zabuza-sama, there is a button here. If you have any questions or travel, just press here."

"I will come over as soon as possible, and I am in the room next to yours. If you have any questions, feel free to call."

Zabuza nodded slightly, and the latter left the room respectfully, closing the door thoughtfully.

Zabuza frowned slightly as he looked at the situation in the room. The room was basically made of wood.

Open the partition and you will find the bathroom and bathroom inside, both with obvious signs and words.

Zabuza just confidently checked the room and found that there was nothing wrong with it, so he sat directly on the bed.

The soft bouncing feeling touched his heart slightly. He slowly closed his eyes and felt the changes in his body.

Under the flow of chakra, he could feel that the root system growing from the seed in his abdomen had spread throughout his body, as if it had become a second chakra system.

The chakra that his body was constantly producing was poured into the seed, and the chakra transformed into it circulated in the root system, seeming to continue to strengthen.

Is this what they call reinforcement?

A trace of doubt arose in Zabuza's heart, and he tried to mobilize the chakra. With just a movement in his heart, the chakra appeared on the palm of his hand without any barrier.

The characteristics of red chakra were clear to him as soon as he used it, and it turned out to be actual chakra.

The image of the battle with Deidara came to mind, and the spear formed by the red chakra made him very embarrassed, and he almost confessed there.

And finally, when he saw the water dragon under the Water Dragon Bullet Technique, he saw the opponent's whole body covered in a red chakra coat.

Did the explosive guy rely on this power to avoid the impact of the water dragon bomb?

Clenching his arms slightly, Zabuza's eyes were gloomy. The more powerful the opponent showed, the deeper the worry in his heart became.

Mist Ninja, can you resist it?

Just oneself can be strengthened in this way. If the other party lets go and strengthens all grass ninjas, what a powerful force is this?

Zabuza silently felt confused about the future for a moment.

…

At this moment, Shengshu was in a laboratory, holding a beheading knife and placing it in front of him.

His eyes were slightly focused, staring at the subtle lines on it, and he stretched out his fingers to cover the chakra.

Click!

Under the strange force, the beheading sword instantly shattered and broke into several pieces.

He used a tray to remove the blade fragments and looked at the remaining half of the beheading sword.

"It absorbs the iron element in the blood to achieve the effect of recovery. It seems that the more blood it drinks, the stronger it becomes. I don't know if it is true or not. It is really an interesting weapon."

The black pupils in his eyes turned into three Magatama Sharingan eyes. Staring at it, you can see the subtle chakra flowing on the surface, finally reaching the symbol on the hilt of the knife.

Those are the runes of necromancy, and the seven ninja swords are all the collections of the Oniden clan.

One of the Mizukage is a member of the Oniden clan, and he uses the Seven Ninja Swords in his clan to form his own personal guard, which is dedicated to taking orders from the Mizukage and handling some difficult tasks.

However, now that the beheading sword has recognized Zabuza as its master, even if the psychic scroll is in the Oniden clan, it cannot be recalled unless Zabuza dies.

Raising his hand, a vine came out, and he threw the decapitating knife into a jar of blood. The red cracks on his forehead slowly opened, and nearby veins popped out.

Roll your eyes, open!

The white chakra vision expanded, watching the beheading sword continue to absorb blood, slowly growing and recovering.

His eyes fell on the fragments again, and he found that as the chakra gradually decreased, the blade fragments were moving towards ordinary metal.

This slightly made Shengshu think deeply. It seemed that the characteristics of the beheading sword did not lie in the blade, but in the handle.

Otherwise, if a few pieces were broken off and used to suck blood, wouldn't there be beheading swords everywhere?

"Interesting secret technique. It seems that the Ghost Lantern clan still has some secrets. They also have the secret technique of transforming into water, but they have not become blood successors."

There are only two blood successor families in the Mist Ninja Village, namely the Minazuki clan and the Taketori (Kaguya) clan.

It is also interesting that the Ghost Lantern clan, as a secret arts clan, can suppress these two clans.

It is obvious that the Ice Release Blood Successor of the Minazuki clan can restrain the Oniden clan, but the Taketori (Kaguya) clan can restrain the Ice Release, forming a mutual restraint.

After discovering that the decapitating sword could not be reproduced, Shen Shu lost interest in it. Looking at the blade that was constantly recovering in the blood tank, he could not understand its principle.

"I wonder if the teacher can figure out the secret of this kind of knife."

I'm afraid Orochimaru is not very interested in the black technology of the ninja world, and it is not as useful as the Kusanagi swords he collected.

Thinking of this, Shengshu finally gave up, and the beheading sword was useless after all.

…

Leaving the laboratory, it was already dark outside.

The rope tree came to an open space outside the building. This was a remote corner of the Grass Ninja Village and had already been cleared away.

Quan Bian also came over and said in a deep voice: "Master Shengshu, a barrier has been set up nearby so that no sound can be transmitted."

"Furthermore, according to research and development, the mirage barrier has been completed, and if it is also deployed, this place will also become a restricted area."

"From the outside, this is just a forest, and you won't notice anything unusual."

Nao Shu nodded slightly. He explained many things about the Grass Ninja Village. Inspired by creation, these Grass Ninjas also worked hard on research and development.

Regardless of whether it is useful or not, as long as it is new, he will give different levels of rewards. This is very simple for him.

"Then...let's begin!"

As Quan retreated, Naoshu raised his hands to form seals and pressed them toward the ground.

"Wood Release: House Tree!"

The earth is normal, and countless giant trees rise from the ground, constantly intermingling and integrating into one, turning into a huge tree.

It covers an area of ​​thousands of square meters, with large trees growing continuously. There are passages, stairs, windows, rooms, and even various furniture inside the entire place.

"drawing!"

"yes!"

With a shout from Naoki, Izumi quickly unfolded the design drawings, and the three Magatama Sharingan quickly scanned it to confirm that there were no errors in the layout and structure.

A large amount of chakra poured out, and sweat slowly dripped down the rope tree's forehead, and at the same time he closed his eyes again.

The details of the drawings have been engraved in my heart, the main body exposed above has been constructed, and the rest is the underground part.

Underground, the entire Cao Ninja Village will be transformed, with an area of ​​tens of thousands of square meters.

As a base, Kusanoin Village cannot change much on the surface because it is too close to Konoha and has trade exchanges.

Many times, Naoki and others do their work at the Ninjutsu Technology Development Bureau.

Now, all he has to do is to actually build a base and start researching what he needs.
Chapter completed!
