The relevant experimental data was recorded immediately. Being able to revive someone with a single Sharingan came at virtually no cost.
"Orochimaru-sensei, if a human body suffered trauma, especially a fatal wound to the heart, could the injured person be revived?"
Although Obito Uchiha was no longer in the Akatsuki, his wish had always been to revive Rin. Now that the technology existed, they could begin reviving those fallen comrades.
"The heart?"
After hearing the question, Orochimaru finished organizing the experimental data and gently shook his head, stating an unfortunate fact:
"The injection site from earlier still bears needle marks. To a certain extent, Life Reincarnation can heal injuries, but it cannot heal them completely. The heart is the most vital organ in the human body. If it has been damaged, the chances of successful revival are very low."
A corpse without a heart was like a funnel. No matter how much Life Energy was poured into it, it would eventually leak out, unable to produce any healing effect.
"Current cloning technology has already matured. I can cultivate a soulless body from the target's cells and use that method to fill the gap left by the original body's heart."
What Orochimaru proposed was not a theory, but a practice built upon vast amounts of data. The clones he cultivated possessed none of the emotions belonging to humans. They were like blank sheets of paper, and such blank sheets could serve as biological replacement organs.
Both of their ideas were insane, especially Orochimaru's. In his eyes, human bodies were merely experimental materials. As long as he could obtain the corresponding experimental data, he would not feel the slightest regret no matter how many people died.
Such cold and merciless sentiments played out daily in the scientific laboratories of Dawn Hidden Village.
