Senju Chen stared at the "eye-gouging" gesture made by Yahiko for several seconds.
He recalled the discussion he had with teacher Orochimaru and Xie about Rinnegan the day before yesterday.
At that time, there was a blackboard in the center of the room.
Three people were just surrounding it.
Concentric circles are drawn in the middle of the blackboard. The innermost circle is painted black, and the outer six circles are equally spaced, becoming lighter and lighter toward the outside.
Senju Chen held the white pen and said to the two people.
"I'll lay out my conclusion first."
"If we can analyze and copy Rinnegan - even if we only copy one of its functions - our White Zetsu Puppet system, we will jump directly from the 'mass production elite' to the 'mass production god' stage."
Orochimaru wiped his tongue on his lips.
Xie sat aside, looking at the blackboard, without saying a word.
"Little Chen." Orochimaru spoke, "I refute your statement from a technical point of view."
"Teacher, please tell me."
"What you think Rinnegan is is the pupil technique." Orochimaru walked to the blackboard, snatched the pen from Senju Chen's hand, and clicked on the black circle in the innermost circle, "But after our previous research on Nagato's control of the puppet, I found that it is not just as simple as the pupil technique."
"Sharingan is a pupil technique. Byakugan is a pupil technique. Their mechanism is 'eyeball structure + Chakra circuit = special vision and special operation'. Such things can be transplanted, modified, and sewn onto others. Because they are essentially organs."
"But if Rinnegan is transplanted, we find that what he gets is not 'stronger eyes'."
Orochimaru turned around, and the light of the lighting ball was reflected in the snake's pupils.
"What you get is the qualification that you can do things that you couldn't do otherwise."
"It's not an organ. It's a permission."
Senju Chen did not interrupt.
This is what he wants - he already has this judgment in his heart, but he needs to hear it from Orochimaru's mouth once, because Orochimaru has "removed" more eyes than he has ever seen.
"To be more precise," Orochimaru pressed the pen tip on the center of the concentric circles, "It may be the only keyhole left by Sage of Six Paths in this world."
"When Progenitor of Chakra left, he locked all the most dangerous things. Demonic Statue of the Outer Path, Tailed Beast's splitting and sealing formats, etc. These locks only recognize one thing - the eyeballs themselves."
Senju Chen smiled, "Teacher, you seem to be quite sorry."
"It's a pity." Orochimaru didn't hide it at all, "If it knew the bloodline, I would have split it into several parts and soaked it."
"..."
Scorpion finally spoke.
"There is another difficulty."
Xie said, "I have made countless puppet eyes."
"I have copied the vision structure of Byakugan, using chip stacking. I have copied the dynamic capture of Sharingan, using double-layer films. I even stuffed magnetic sensing eyeballs into the puppet of Third Kazekage."
"I can copy the shape. I can copy the Chakra circuit. I can also copy the neural interface."
"But I can't copy this permission 'authentication'."
"What is certification?"
"That is, before opening the lock, it will first ask, 'Who are you?'" Xie raised his head, the expression on his face did not change at all, "I can't answer the question because of my eyes."
The room was quiet for a few seconds.
Senju Chen nodded, walked over, and took the white pen back from Orochimaru's hand.
"So I'm not ready to copy Rinnegan directly now."
Next to the concentric circles, he drew a square box.
"Teacher, Scorpion, I agree with everything you two just said. Eyeballs cannot be copied, and certification cannot be copied."
"Then let's change the angle."
"Summon Demonic Statue of the Outer Path, what does it recognize?"
Orochimaru narrowed his eyes.
"It's those eyeballs."
"No." Senju Chen said, "It's the thing that comes out of those eyeballs."
He wrote two words in the box: Waveform.
"Demonic Statue of the Outer Path has no brain, it is the shell of Ten-Tails. It cannot think, it can only respond." Senju Chen Use the pen tip to connect the square boxes and concentric circles, "Nagato When summons it with Rinnegan, the eyes send out a Chakra vibration. This vibration has a specific frequency, phase, and level sequence - the sixth layer, corresponding to Six Paths."
"Demonic Statue receives this vibration, compares it, passes it, and then moves."
"It doesn't know Nagato. It only knows that wave frequency vibration."
Xie suddenly stood up from the ground because he knew what Senju Chen was talking about.
"You want to copy that unique frequency."
"Yes." Senju Chen said, "We don't copy the key. We just need to record the sound of the lock opening."
Orochimaru's shoulders began to shake.
When he laughed, his voice was very low, rolling out of his throat and getting louder and louder.
"Ha... hahahaha."
"Little Chen, you are such a genius, you are trying to forge the key of God."
"No." Senju Chen put down the pen and turned around, "Teacher, your words are out of context."
"Forging a key means using a fake key to cheat a lock."
"What I want to do is the master."
He stretched out a hand and spread his fingers.
"We can try to completely record each different waveform of Rinnegan, analyze the structure of each layer, and then engrave it into the core of the puppet. Then every White Zetsu that grows from Demonic Statue of the Outer Path will have this waveform when it leaves the factory."
"Sage of Six Paths was just a man who could pick locks. He made the lock, hid the key, and then told everyone who followed for thousands of years: this cannot be touched."
"Why?"
"Is it because he came first?"
Senju Chen Cross out the concentric circles on the blackboard with one stroke.
"Then I'm here now."
"What do you need?" Xia was silent for a long time, but his eyes became more and more fanatical.
"Collection array." Senju Chen replied immediately, "Six layers of nesting, each layer records a phase separately. The core uses the batch of induction crystals we made Soul Conversion Device last time. The outer ring must be completely shielded, and not a trace of Chakra can leak out."
"So strict?"
"Because if this waveform leaks even half a tone," Senju Chen said, "Demonic Statue of the Outer Path may wake up, or even be directly summoned by Nagato. That guy's size cannot be accommodated in our experimental base."
Xie walked directly to the door. "Three days."
"Two days."
"Three days." Xie didn't even look back, "I won't make defective products."
The door is closed.
Orochimaru walked to the blackboard and looked at the crossed out concentric circles for a long time.
"Little Chen."
"Hmm."
"Have you ever thought about a question?" Orochimaru touched his fingers on the blackboard, and the chalk dust rubbed against his fingertips, "Why do those eyes grow on Nagato's body?"
