"Save your strength trying to escape. You're not getting away, so just cooperate and we'll proceed with the experiment," Satori Hyūga said coldly, his expression cold and indifferent as he stared at Bei Gongcheng.
Without missing a beat, he activated his Byakugan to observe the changes within Bei Gongcheng's body and the flow of chakra.
Stimulated by electricity, Bei Gongcheng's cells had fallen into chaos and begun to break down. His chakra, once stimulated, now surged chaotically.
Like an incredibly precise instrument, the Byakugan revealed every detail—clearly displaying the movement of chakra and the activity of cells deep inside the human body.
As the current steadily increased, instead of stimulating cellular activity, it simply began to "cook" the cells.
Soon, it might be time to serve dinner.
Satori flipped the switch off, ignoring the collagen particles floating in the air, and began recording these changes.
Experiments were always this dull—set a goal, then endlessly speculate and test through trial and error.
With a pen in hand, Satori jotted down notes on a blank sheet of paper, occasionally lifting his eyes to check up on Bei Gongcheng.
This strange behavior deeply unsettled Bei Gongcheng, making his very bones shiver with fear and horror.
He didn't know that Satori was Orochimaru's apprentice—he assumed he was just an ambitious young man from the Hyūga Main House striking out on his own.
Yet the laboratory around him and the experiments being performed on his own body told another story—one that made it clear Satori wasn't a good person.
Then again, how many decent people conduct human experiments?
As his eyes glazed over and he braced himself for death, Satori suddenly said, "Cooperate with my research, and I'll give you a chance to live."
"There's lightning-natured chakra inside you. I'm currently researching Lightning Release cellular activation. If you cooperate, I won't harm you too badly."
The earlier experiment had proven that random electrical shocks alone could never properly stimulate cellular activity.
To activate the cells, like the Kage of Cloud Village had achieved, he needed actual Lightning Release chakra nature transformation.
That was exactly why Satori had made this offer.
Naturally, Satori hoped his test subject would fully cooperate—to maximize the experimental benefits.
And though he promised not to harm Bei Gongcheng during the tests, he certainly never mentioned releasing him afterward.
There were still so many research projects left to conduct; Satori had no intention of letting his test subject go.
Bei Gongcheng wore a conflicted expression, but after some hesitation, finally lowered his head.
"I agree. While I'm helping with your experiments, you can't hurt me. Afterward, you must let me leave."
Since becoming a ninja, Bei Gongcheng had long since left behind a peaceful life, constantly facing danger and difficult situations.
Being a test subject wasn't unthinkable—he believed he could eventually find a way to escape.
For now, his plan was to play along, make Satori believe in his compliance, and wait for the right moment to flee.
Once he escaped, exposing this lab could even fetch a hefty price on the intelligence market.
"Fine. As long as you help me complete the experiment, I'll let you go," Satori readily agreed.
He'd said "experiment," but hadn't specified how many experiments—or how long that might take.
Each concealing their true intentions, the two embarked on a tentative partnership.
Satori Hyūga discarded his previous experiments with chaotic electric currents and turned his focus toward using Lightning Chakra to stimulate cells.
Lightning Release resembled ordinary electricity to some extent, but it involved intrinsic transformations of lightning-natured chakra, capable of directly affecting the muscles.
This concept bore a certain resemblance to his own Feeding-Back Jutsu, though there were differences as well.
The cellular activation through Lightning Release was a secret technique that boosted physical prowess by channeling lightning-natured chakra as its base.
In contrast, Feeding-Back Jutsu utilized undifferentiated chakra. The two techniques produced somewhat similar results but differed in their methods of application.
Satori scribbled sketches and notes onto paper, incorporating methods of stimulating acupoints and meridian circulation into his experiment.
Once his plan was complete, Satori spoke indifferently, "Prepare yourself. We'll begin the second experiment."
He fastened a sealed ninja tool to Bei Gongcheng's body and stimulated several acupoints on his torso.
At once, Bei Gongcheng regained feeling and slowly sensed his ability to refine chakra returning.
With a sudden *Zila* sound, Bei Gongcheng shook like a leaf caught in a storm and involuntarily collapsed to the ground.
"Don't attempt anything reckless. My tools can allow chakra to circulate inside you, but you won't be able to use any Ninjutsu."
"Even if you did try a jutsu, it wouldn't harm me much, but unnecessary noise will irritate me," Satori said calmly, looking at Bei Gongcheng.
Bei Gongcheng hastily nodded. Inside his body, a strange chakra ran wild, burning and itching as if his blood were on fire.
