Orochimaru's eyes showed some surprise, "You actually know this secret technique?"
Rengoku smiled awkwardly, "Indeed I do, but the consumption of life force is very large."
"You need roughly a two-to-one consumption."
Orochimaru's expression was astonished, "Then if this secret technique doesn't have the Water of Life, isn't it useless?"
With a two-to-one consumption, one life could only save a child or a small animal.
Truly a garbage ability.
Rengoku helplessly smiled; this Dragon Life Rebirth technique itself is the bloodline limit of the Ryuzetsu. It requires their clan to learn.
Rengoku used the Bond Star to fleece a bit of wool; even with doubled consumption it can only be this way.
"Now that we have the Water of Life, it's still more cost-effective than using the Rinnegan innately."
Just then, Karin poked her head in.
She was deeply favored by Rengoku, so naturally no one stopped her.
"Shishou—"
"What happened to Gaara?"
Karin only saw Gaara lying on the bed with eyes tightly shut, not knowing Gaara had already died.
After all, neither Rengoku nor Orochimaru's faces showed any sadness.
She hadn't thought more about it.
Orochimaru looked at Karin, light shining in his eyes.
He spoke directly, "Gaara is already dead."
"What?", Karin was a bit dazed; just a few days ago the partner had been fine, how could he be dead now?
Before she could react, Rengoku glared at Orochimaru, "It's fine, Karin, I can save him."
Karin's heart, which had just risen, immediately settled down.
"Then Shishou hurry and save him."
Orochimaru smiled, "If you Shishou saves Gaara, you will lose a large amount of life."
"So we need your ability to help."
Rengoku frowned at Orochimaru, "Orochimaru, what are you trying to do?"
Orochimaru pointed at Rengoku's eyes, "Isn't now just the right time?"
Rengoku slightly frowned, "Karin is still too young."
Hearing the two argue, Karin thought Rengoku didn't want to use her ability and hurriedly said, "It's okay Shishou, I can do it."
Knowing Rengoku favored Karin, Orochimaru changed his wording, "Let Karin transform, it can continuously activate her cells; it's only beneficial to her, no harm at all."
"All right then," Since it harms Karin not, Rengoku consented.
Orochimaru hurriedly had Kabuto bring various monitoring kits, fitting both Rengoku and Karin with them.
The Water of Life IV drip was also attached to Karin.
"Begin!"
After all monitoring was in place, Orochimaru said to Rengoku.
He looked impatient.
Gaara's corpse shouldn't be left too long; Rengoku pressed both hands on Gaara's body.
He cast the Dragon Life Rebirth technique!
A vast surge of life force poured into Gaara's body.
Because it was double the life consumption, in just a few seconds Rengoku's hair visibly turned white to the naked eye.
"Ah, Shishou! Hurry!", Karin quickly offered her wrist.
Rengoku glanced at Orochimaru; Orochimaru gave an OK gesture.
Only then did he confidently bite down.
Karin muffled a groan as her body's life force flowed step by step toward Rengoku.
When she was seven, she had healed Rengoku once.
After that time, Karin and her mother were protected.
Later they were taken in by the Uchiha clan, and no one forced Karin and her mother again.
Now three years had passed, and only Rengoku used her ability again.
Only this time the life force drained especially fast; the energy inhaled into his body was huge, and Karin was sucked dizzy.
Kabuto next to them sped up the Water of Life IV drip, and Karin recovered a bit.
Life on one hand drained, on the other hand wildly regenerated.
Karin's body temperature gradually rose, sweat pouring all over.
If not for the Water of Life, Karin would already have been drained to death.
Rengoku had finally input enough life into Gaara's body.
With Gaara's heart beginning to beat, Rengoku withdrew his hands and released Karin's wrist.
Karin sat panting on the nearby bed, her whole body steaming.
That feeling just now was like first taking a cold shower (life force loss), then soaking in a hot bath (Water of Life infusion), and finally running dozens of laps on the playground.
Seeing Karin was okay, Rengoku relaxed.
Kabuto took off Karin's monitoring gear; Karin energetically hopped off the medical bed, bounced on the floor twice, and puzzled said, "I feel like I'm a bit different."
Orochimaru smiled, "Your Uzumaki bloodline cells are now highly activated, so you will be full of energy and your physical fitness will strengthen."
"Hehe! That's awesome!", Karin pumped a small fist, feeling her fist stronger than before, she was ecstatic.
Orochimaru glanced at the monitoring data on the machine, then continued instructing, "You will grow taller in the coming time; this is normal."
"Grow taller? Hahaha! Then I'll be Sasuke's senior sister!"
As a child, she had pride and cared about her height.
Being taller than Sasuke would make Karin even happier.
Then she saw Rengoku's hair and anxiously asked, "Shishou, when will your hair change back?"
Orochimaru explained, "No worries, hair regrowth cycles are slow; your Shishou will take some time to revert."
Karin patted her chest, "Then I'm relieved."
Rengoku saw Karin sweating all over, "Go wash up first, Gaara will recover soon."
Karin wiped the sweat from her forehead; seeing Gaara breathing evenly, she too relaxed.
"I know, Shishou."
Then she dashed out.
Rengoku slapped Orochimaru's shoulder with one hand, "What do you mean Karin will grow taller?"
Orochimaru nodded, "Exactly what you think."
"Won't this affect her future growth?"
Orochimaru chuckled, "How could it? Under abundant life energy, her cells will turn over more. So only the growth time is shortened; now, the problem is yours."
Rengoku was puzzled, "What problem of mine?"
Orochimaru looked at the monitoring machine with a half-smile, "Soon, soon…"
Rengoku slowly felt his body warming, and this heat was spreading throughout.
Finally the same feeling reached his eyes.
"Hiss…", Rengoku's eyes felt some discomfort.
"Yin and Yang unified, the Power of All Things?"
Rengoku clearly perceived his pupil power recovering somewhat, and in total amount there was also some expansion.
Orochimaru's face was full of excitement, "Yes, precisely Yin-Yang unity, the Power of All Things."
"Previously you had me research the First Hokage's cellular solution."
"Inside is extremely strong Yang-release chakra."
"Being able to fuse the First's cells is beneficial for Yin-Yang unity to produce the Power of All Things that enhances the eyes."
"But the First's cellular will is too strong, and easily turns the failed into trees."
"Karin's healing ability still has cell-invading power, but it's safe, and it has already invaded into your body."
"So you will produce a small amount of the Power of All Things."
