Senju Chen led Rin Nohara to find Orochimaru who was busy.
"Teacher." Senju Chen nodded, "This is what I told you Rin Nohara."
Orochimaru's eyes fell on Lin.
At that moment, Lin felt like she was being stared at by something cold and sticky.
"Three-Tails Jinchūriki..." Orochimaru licked his lips, "Interesting."
He stepped forward and circled around Lin.
"The location of the charm is near the heart?"
"Yes." Senju Chen replied.
"Well..." Orochimaru nodded, "Let's do a comprehensive inspection first. Amado, prepare."
"Understood."
Amado stood up from behind the experimental table and pushed up his goggles.
"Little girl, come with me."
Rin Nohara glanced at Senju Chen.
Senju Chen nodded towards her.
Rin Nohara took a deep breath and followed Amado towards the depths of the laboratory.
Senju Chen stood there, looking at her back, with a trace of complicated emotions flashing in his eyes.
"Little Chen." Orochimaru suddenly said, "Are you... very concerned about this girl?"
"That's right." Senju Chen did not deny it. "She is Kakashi's companion, and maybe she will be Kakashi's future wife."
"Haha..." Orochimaru laughed
He knows what Orochimaru is thinking.
In the eyes of Orochimaru, human life is just experimental material. But Senju Chen is different. He has his own bottom line.
At least, he will try his best to protect those who are worthy of protection.
"By the way, teacher." Senju Chen suddenly remembered something, "Kakuzu over there..."
"Oh, that old guy." Orochimaru's smile deepened, "The first stage of transformation has been completed. Now he is adapting to the new heart."
"How's the effect?"
"Very good." Orochimaru licked his lips, his eyes flashing with excitement, "His Earth Grudge Fear is more valuable for research than I thought. The structure of those black lines, the person who invented this Ninjutsu is simply a genius."
"And..." He paused, "Amado and I have found a way to combine Tailed Beast cells with Earth Grudge Fear. If successful..."
Senju Chen's eyes lit up.
"If it succeeds..." Orochimaru's smile became even weirder, "That old guy's strength will make a qualitative leap."
Deep in the laboratory, there is an independent examination room.
Rin Nohara was lying on a cold metal table, with various instruments connected to her body. Those cables were wrapped around her body like a spider web, and each one shone with a faint blue light.
Amado stood aside, moving his fingers quickly on the console, and a string of data scrolled on the screen.
"My heart rate is too fast, I'm short of breath..." He pushed up his goggles, "Little girl, relax. I'm just doing a routine check-up."
Lin bit her lip and said nothing.
She looked past Amado and looked outside the examination room.
Through the glass window, she could see Senju Chen standing there, nodding towards her.
That gentle smile made her tense nerves relax a little.
"Found it." Amado suddenly said, tapping a certain position on the screen with his finger.
On the screen, a complex rune pattern appeared.
Those lines are densely packed and layered, like a precise mechanical device.
"This is the core of the spell." Amado's tone became serious, "It is located near the left ventricle of the heart and is closely connected to the aorta."
He enlarged the image.
Rin Nohara could clearly see that those runes were like parasites, deeply rooted in her heart tissue.
It's just that the outer layer is wrapped by a golden chain.
"How is it?" Orochimaru's voice came from the door.
He walked into the examination room and stared at the image on the screen with his golden vertical pupils.
"It's more troublesome than expected." Amado frowned, "The charm is not only connected to the heart, but also forms a resonance circuit with Three-Tails's Chakra."
"Resonant circuit?"
"Yes." Amado called up another set of data, "Look here, the spell will release a weak Chakra fluctuation every three seconds, and the Chakra of Three-Tails will react simultaneously."
"This resonance is like a lock and key." Orochimaru licked his lips, "Once the spell is destroyed, Three-Tails will go berserk."
Rin Nohara's face became even paler.
"But..." Amado changed the subject, "This also gives us a breakthrough."
"Oh?" Orochimaru became interested.
"Since it is resonance, we can use the reverse frequency to interfere." Amado called up a waveform on the console, "We can create a 'false signal' to make Three-Tails mistakenly think that the spell is still there, thus avoiding the rampage."
"Then take advantage of this time gap to cut off the connection between the charm and the heart." Orochimaru took over the conversation, with a flash of excitement in his eyes, "Wonderful."
The two looked at each other and saw the same madness in each other's eyes.
Rin Nohara was lying on the metal table, listening to these two madmen discussing how to "disassemble" her body. She felt like a machine waiting for repair.
"Well..." she said carefully, "How long will it take?"
"The preparation will take about three days." Amado replied, "The operation itself... if it goes well, it will take two hours."
"What if it doesn't go well?"
"Then..." Amado pushed up his goggles, "It may take four hours."
"..." Rin Nohara.
This horse riding is not the point at all, right?
"Don't worry." Orochimaru patted her shoulder, "Amado and I have teamed up and we haven't failed yet."
Rin Nohara would like to ask: Are those "experimental subjects" in the culture tanks your "successful cases"?
But she swallowed the words in the end.
Outside the laboratory.
Senju Chen looked at the scene inside the glass window with a playful smile on his lips.
"It seems that Lin-san is a little nervous."
"Nonsense." A hoarse voice came from the side, "If you were lying there, you would be nervous too."
Senju Chen turned his head.
Kakuzu is leaning against the wall, his face still that sickly green color.
But compared to before, his complexion was obviously much better.
At least... he no longer looks like he is about to die at any moment.
"Hey, old guy, you're recovering well." Senju Chen walked over with a smile, "Are you still getting used to the new heart?"
Kakuzu's face twitched.
"... not bad."
There was a hint of unspeakable frustration in his tone.
In the past few days, he has finally seen what "the power of science" is.
The two madmen, Orochimaru and Amado, studied his body from the inside out.
What blood samples, tissue sections, Chakra fluctuation analysis...
He felt like a dissected frog.
And the most damning thing is...
These two lunatics actually replaced five of his hearts, even his own.
