Thunder, wind, water, fire, earth - five Chakra attributes are complete.
Every heart is taken from the "high-end goods" in the culture tank.
The quality is really nothing to say.
But the problem is...
This fucking process is so tortured!
"By the way." Senju Chen suddenly remembered something, "The teacher said, how is the fusion experiment of your Earth Grudge Fear and Tailed Beast cells going?"
Kakuzu's face turned green again.
"... still in testing phase."
His voice was trembling a little.
Tailed Beast cells...
That thing is a nightmare.
Orochimaru and Amado injected those cells into his black lines and observed the reaction.
At first, Kakuzu thought it was no big deal.
Result...
Those Tailed Beast cells were like living creatures and began to devour his Chakra crazily.
The whole process was like countless ants crawling in his veins.
That pain...
Kakuzu has lived for more than ninety years and has never experienced this before.
"But the effect is really good." He took a deep breath and stretched out his right hand.
Black lines extended from his arms, twisting in the air.
But the difference from before is...
The surface of these lines has a faint dark red sheen.
"This is..." Senju Chen's eyes lit up.
"Characteristics of Tailed Beast Chakra." Kakuzu said with a hint of complexity, "After those cells were fused with my Earth Grudge Fear, they not only enhanced the toughness of the lines, but also gave them a certain ability to 'regenerate'."
He clenched his fists.
Those black lines instantly retracted from the body.
"And..." Kakuzu paused, "Chakra's recovery speed has also been improved a lot."
Senju Chen nodded with satisfaction.
It seems that Orochimaru and Amado really made something famous this time.
"Very good." He patted Kakuzu on the shoulder, "Come to me when you have fully adapted to the new power."
"... I know."
He has no choice now.
There are marks left by Senju Chen on his body, and he cannot escape even if he wants to.
And...
After these few days of "transformation", his strength has indeed improved a lot.
I am no longer so resistant to "working" for Senju Chen in the future.
"That's right." Senju Chen suddenly remembered something, "I've already asked someone to collect your bounty on the black market."
"What?!" Kakuzu's voice suddenly rose.
"Don't get excited." Senju Chen waved his hand, "You are mine now, and your bounty is naturally mine as well."
"And..." He smiled, "I spent a lot of money to replace your heart and make modifications. I have to make this money back from you, right?"
Kakuzu's face turned completely black.
So...
Not only did he have to work for Senju Chen, but his own bounty was swallowed up by this kid?
"You..."
"What's wrong with me?" Senju Chen looked innocent, "Old man, you don't think that I will help you in vain, do you?"
Kakuzu took a deep breath, turned around and left.
Now he just wants to find a place to be quiet.
Don't be pissed off by this Senju Clan brat anymore.
Three days later.
Laboratory operating room.
Rin Nohara was lying on the operating table, with more instruments connected to his body.
Those cables were so densely packed that they almost covered her entire body.
Orochimaru and Amado stood on both sides of the operating table, holding various surgical instruments in their hands.
"Are you ready?" Orochimaru looked at Amado.
"You can start at any time." Amado pushed up his goggles.
"Then let's get started."
Orochimaru picked up the scalpel and made an incision on Lin's chest.
Blood gushed out instantly.
But soon, those Scientific Ninja Tool came into play.
A transparent device was placed on the wound and began to temporarily take over Lin's heart function.
"The first step is completed." Amado's voice was very calm, "Start cutting off the connection between the charm and the heart."
Orochimaru's hand is as steady as Boulder.
The scalpel moved around Lin's heart, cutting off the runic lines bit by bit.
Each time one is cut off, the data on the screen will jump once.
"Be careful." Amado suddenly said, "Chakra of Three-Tails is starting to fluctuate."
"I know." Orochimaru licked his lips and "activated the 'false signal' device."
Amado Press a button.
A special Chakra wave is released from the device, simulating the frequency of the spell.
The Chakra fluctuations of Three-Tails gradually stabilized.
"Successful." Amado breathed a sigh of relief.
"It's not over yet." Orochimaru continued cutting, "The last one..."
"Click--"
The last rune line is cut off.
Lin's body twitched violently.
"Hold on!" Amado quickly adjusted the parameters of the device.
After a few seconds, Lin's body gradually calmed down.
"Successful." Orochimaru put down the scalpel with a satisfied smile on his face, "Carry out the final peeling work."
Amado's fingers moved quickly on the operating table.
On the screen, the complex spell pattern was peeling off Rin Nohara's heart tissue bit by bit.
Each time a layer is peeled off, the data will jump.
"Pay attention to the Chakra fluctuations of Three-Tails." Orochimaru's voice was very calm, and the scalpel moved accurately in Lin's chest, "The frequency of the false signal device must remain stable."
"Understood." Amado stared at the screen, beads of sweat dripping from his forehead.
There is no room for error in this kind of surgery.
Once Three-Tails realizes that the talisman has been destroyed, a rampage is inevitable. At that time, not only Rin Nohara will die, but the entire laboratory will be buried with him.
"The last layer." Orochimaru licked his lips.
The tip of the scalpel touched the core of the spell.
It was a rune crystal the size of a thumb, deeply embedded in the left ventricular wall of Lin's heart.
"Prepare Sealing Jutsu."
Amado picked up a special container from the side, which was filled with some kind of transparent liquid.
Orochimaru Take a deep breath.
The scalpel jerked.
"Chi--"
The rune crystal was completely peeled off.
Lin's body twitched violently.
"Hold on!" Amado quickly threw the crystal into the container and at the same time increased the output power of the false signal device.
A few seconds of silence.
The data on the screen gradually stabilized.
"Successful." Orochimaru put down the scalpel with a satisfied smile on his face.
Amado also breathed a sigh of relief and pushed up his goggles.
"The next step is suturing and repair work." He looked at Orochimaru, "Do you need that?"
"Yeah." Orochimaru nodded, "Hashirama Cells's diluent, use the lowest concentration."
Amado took out a reagent from the refrigerator and carefully injected it into Lin's heart tissue.
The parts eroded by the spell began to heal at a speed visible to the naked eye.
"It's such a convenient thing." Amado sighed, "No wonder First Hokage can be called 'God of Shinobi'."
"Haha..." Orochimaru smiled and did not answer.
His eyes fell on Rin Nohara.
This girl's physique was even more special than he imagined.
Not only can it withstand Three-Tails's Chakra, but it can also endure the torture of the spell for such a long time.
If it weren't for Senju Chen opening...
Forget it, there are a lot of experimental subjects.
