The relevant experimental data was recorded immediately. Using a single Sharingan to revive someone 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 was not in Akatsuki, his wish had always been to revive Rin. Now that the technology existed, they could begin reviving those companions who had already died.
"The heart?"
After hearing the question, Orochimaru finished organizing the experimental data and gently shook his head, stating a helpless fact:
"The injection site from earlier still bears needle marks. Life Transfer Reincarnation can heal injuries to a certain extent, but it cannot heal them completely. The heart is the most important organ in the human body. If it is damaged, the chances of revival are very low."
A corpse without a heart was like a funnel. No matter how much life energy was injected into it, it would eventually flow out through the funnel, unable to produce any healing effect.
"The cloning technology is already complete. I can cultivate a soulless body from the person's cells and use this method to fill the gap left by the original heart."
What Orochimaru proposed was not theory, but 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 it was precisely such blank sheets that could serve as replacement organs.
Both of their ideas were insane, especially Orochimaru's. So-called human bodies were merely experimental materials in his eyes. If he could obtain the corresponding experimental data, no matter how many people died, he would not feel any heartache.
Such cold and merciless sentiments played out every day in the scientific laboratory of Dawn Hidden Village. They were all
