Is Orochimaru in "Naruto" really immortal?

Haha, this is an interesting question. What is the difference between the immortal bodies of Orochimaru and Hidan in Naruto? Personally, I think there are obvious differences in implementation means and specific effects. I will explain them in detail below. Orochimaru's so-called immortality is not that he has strong resistance to physical output, but that he can extend his life through technical means.

As a technological expert in Naruto, Orochimaru has done a lot of research on how to obtain immortality and has achieved certain results. Compared with Hidan, Orochimaru's so-called immortality is not based on strengthening the body's resistance to physical output, but relying on technical means to allow Orochimaru to transfer his soul or use a carrier to resurrect. Orochimaru will also be injured in battle and even the physical functions that carry his soul will be exhausted. However, he can use the special effects of immortal reincarnation and curse seals to transfer his soul in different carrier containers to achieve the effect of immortality. . Orochimaru's steps to achieve immortality are quite cumbersome and difficult. There may be backlash in the process of seizing other people's souls. Of course, even if Orochimaru's soul goes wrong, he has a curse seal as a backup. Therefore, objectively speaking, I personally think that the first difference between Hidan's immortality and Hidan's immortality is the ability to resist physical output, and the second is that the means and paths to achieve immortality are different.

Orochimaru's immortality is achieved by using technological means to allow his soul to reside in other carriers, or to recreate his body to achieve the effect of immortality. Compared with Hidan, the technical difficulty is higher and the risk is not low, but the effect of dealing with complex and changeable situations is better than Hidan. Hidan's immortality is achieved by relying on a specially modified body. The body's ability to resist physical output is strong, but its scalability is average.

In the plot, Hidan is a member of the Evil God Cult. Through special means, his body has been specially modified to have strong immunity to physical output. However, friends who are familiar with Hidan's abilities know that even if Hidan is against The ability to withstand pain and conventional physical injuries is far beyond that of ordinary people, but it still cannot get rid of the need to absorb nutrients from the outside world to maintain normal physiological activities. Therefore, to a certain extent, Hidan's immortal body is not perfect and cannot achieve an effect similar to that of Kaguya Otsutsuki, who can survive without eating or drinking. Compared with Orochimaru, the advantage of Hidan's immortal body lies in its strong resistance to physical output. At the same time, because the skill activation process is not complicated, there are no various risks faced by Orochimaru in the process of realizing soul transfer. However, the disadvantage lies in Hidan's so-called His immortal body has poor expansibility and cannot transfer his soul. Once there is no supply of external nutrients, Hidan's immortality cannot be maintained.

Hidan’s immortality is due to his specially modified body that has a good ability to resist conventional physical output. It is unknown whether his lifespan can be extended by this method, and the so-called immortality is abolished. The body must rely on constant eating to maintain a large amount of energy in the body. Once there is a problem with nutritional maintenance, Hidan will also die.

Finally, to summarize, objectively speaking, I personally think that neither Orochimaru nor Hidan are immortal in the complete sense. They are just methods of extending their lifespan through technical means. The difference between the two lies in their realization. I have different methods of avoiding external harm. Please forgive me for the imperfect analysis. If you have other ideas, please leave a message for discussion.
