When leaving Land of Iron, Amado only brought two boxes.
One contains his most important research materials, and the other contains his messy experimental equipment.
As for the others?
"Those scraps of scrap metal, just throw them away." Amado pushed up his goggles, with a hint of relief in his tone, "Anyway, they are just decorations in that damn place."
Look at this scientist's rare relaxed expression.
Senju Chen thought to himself that this guy is really a pure pragmatist. But yes, for people like Amado, the real value is always the knowledge in their heads, not tools that can be copied at any time.
The two of them headed south, passing through snow-capped mountains and forests, and finally entered the territory of Land of Fire three days later.
"The air here... is much more comfortable than Land of Iron." Amado took a deep breath and made a rare comment.
"That's natural." Senju Chen smiled, "Land of Fire is the richest place in Shinobi World. However, the place we are going to is not a scenic spot."
"Oh?" Amado raised his eyebrows, "Where are you taking me?"
"Go and meet someone." Senju Chen's mouth curved in a playful way, "A guy who is just like you, not normal."
Land of Fire, a secret underground base somewhere.
This place is located deep in a dense forest outside Konoha. The entrance is hidden in a huge ancient tree Root. If Senju Chen hadn't led the way, even a perceptive ninja would have had a hard time detecting anything unusual here.
"This is..." Amado looked at the deep passage in front of him, with a flash of interest in his eyes.
"My teacher Orochimaru's private laboratory." Senju Chen explained as he walked, "He is one of Sannin's Sannin's from Konoha, and he is also my teacher. However, his research direction... well, how should I put it, is a bit similar to yours."
"Kind of like?" Amado captured this word keenly, "You mean, he is also doing human body modification?"
"It's not just human body modification." Senju Chen's voice echoed in the dark passage, "Cell transplantation, soul reincarnation, development of forbidden arts... As long as it is research that can make people stronger, he is interested."
Amado's eyes lit up instantly.
"Sounds like... an interesting guy."
The two of them went deep along the spiral downward passage.
On the wall of the passage, a faint green light will light up at regular intervals, illuminating the road ahead. The air is filled with a faint smell of formalin, mixed with some unexplainable fishy smell.
Amado not only did not frown, but took a deep breath with a satisfied expression on his face.
"This smell... is a mixture of culture fluid and preservatives. It seems that Mr. Orochimaru is indeed doing some interesting research."
Senju Chen The corners of his mouth twitched.
These two guys are really the same thing.
Finally, the two came to the end of the passage.
In front of you is a thick metal door. The door is engraved with complex magic patterns, and you can vaguely feel a powerful Chakra wave.
Senju Chen stepped forward, pressed his palm on the door, and injected a stream of Chakra with a specific frequency.
"Click--"
Accompanied by the sound of mechanical gears turning, the thick metal door slowly opened.
A stronger potion smell hit his face.
Behind the door is a huge underground space.
Around the space, there are countless huge glass culture tanks. In the tanks, there are various "experimental subjects" soaked - some are human-shaped, some are animal-shaped, and some... the original form cannot be seen at all.
The dark green culture medium glowed with a strange luster under the illumination of the light.
And in the center of this "forest", a figure wearing a white robe was facing away from them, concentrating on operating something in front of an experimental table.
"Teacher." Senju Chen said.
The figure paused for a moment, then slowly turned around.
Pale skin, narrow golden vertical pupils, and a playful smile at the corner of his mouth.
"Hehehe...Little Chen, long time no see." Orochimaru's voice is hoarse and magnetic, with an indescribable allure.
His eyes fell on Amado behind Senju Chen.
Those golden vertical pupils narrowed instantly.
"Oh? This is..."
"Amado." Senju Chen simply introduced, "A scientist specializing in human body modification and Scientific Ninja Tool development."
"Scientist?" Orochimaru's smile deepened, "The one you mentioned last time?"
He stepped forward and looked at Amado with a trace of doubt in his eyes.
"You... don't have Chakra's fluctuations." Orochimaru suddenly said, "Are you not a ninja?"
"I don't need Chakra." Amado replied expressionlessly, "That kind of unstable power is just a research object for me, not a tool to rely on."
Orochimaru's eyes flashed with a hint of surprise.
Then he laughed.
Smiling happily.
"Hahahaha... interesting, so interesting!" Orochimaru's laughter echoed in the empty underground space, "Little Chen, the people you brought this time are really to my liking."
He turned around and looked at Senju Chen.
"Tell me, what do you want me to do?"
"It's very simple." Senju Chen shrugged, "Provide him with a laboratory and... necessary resource support."
"That's it?" Orochimaru raised his eyebrows, "You are not a person who makes losses."
"Of course not." Senju Chen smiled, "In exchange, we can share his research results. And..."
He paused and said meaningfully, "I think you two should have a lot in common."
Orochimaru and Amado looked at each other.
There seemed to be something quietly fermenting in the air.
"A common language?" Orochimaru licked his lips, "Then we should have a good chat."
He walked to the experimental table nearby and picked up a test tube containing a light green liquid.
"This is what I have been studying recently - Tailed Beast's cell culture fluid." Orochimaru shook the test tube, "It has amazing vitality and regeneration capabilities, but at the same time, it is also extremely corrosive. The body of an ordinary person simply cannot withstand its power."
Amado took the test tube and looked at it carefully.
"Energy overload at the cellular level..." he murmured to himself, "If we could find a way to output this energy stably instead of letting it explode randomly..."
"That's right." Orochimaru's eyes flashed with excitement, "I have tried many methods, but the success rate is extremely low. Most of the experimental subjects were devoured by cells within a few days after transplantation, and there is only one successful case so far."
"That's because your method is too rough." Amado pushed up his goggles, "Direct transplantation will of course cause rejection. What you need is a buffer layer - a medium that can isolate cell energy while allowing the host to gradually adapt."
Orochimaru was stunned for a moment.
Immediately, his smile became even brighter.
"Interesting... go on."
