In Naruto, why not use ghosts to seal the seal points?

The starting standard comes from the technology of the whirlpool clan, which sacrifices its own soul to die, so it pulls itself and the other person's life into the belly of death, and always hates each other and fights. This technology is forbidden, and not many people learn it well. This is a ... Secondly, the shortcomings of corpse ghost print are also very obvious. First, when Kyubi no Youko sealed it, only half of it was sealed, and when orochimaru sealed it, only two hands were sealed, that is, this technique cannot be sealed by 100%. At that time, people may know that ghosts can't seal the scene, so they died in vain. Many serious ninja books in Naruto didn't happen at the beginning.

For example, the death of ghosts is such a professional skill. Although the actual effect is peerless, this professional skill should only be known to the Vortex family in the active stage of Uchibo Madara, and it will only be moved to Muye Village for protection when the Vortex family is eliminated. Although the Thousand-Handed Clan and the Vortex Clan are distant relatives, only a few warriors can master the uniqueness of ghost prints. So, in fact, the first generation of Huo Ying did not seal such professional skills, so this skill was not applied in the battle of columns and points. Until the back spot is reincarnated with filthy soil and naturally reborn, no warrior will try his best to seal the ghost.

Sarutobi Hiruzen and Boshuimen are in samsara, so it should be impossible to seal them with ghosts. In addition, the working ability of the Sixth Route Reconstruction in the middle and late period is too strong, so it is not easy to spell Uchibo Shoko Asahara easily. Secondly, because of technical reasons, ghosts have been sealed. If you want to use this ninja encyclopedia, you must summon death at the cost of your life. People reincarnated by filth are lifeless. Scientifically speaking, four generations of Huo Ying can't be called death. Before calling death, you must drink some of your own blood. In the case of filth reincarnation, Namikaze Minato has no blood, so Namikaze Minato can't use this ninja encyclopedia. From these perspectives, it is not easy for Namikaze Minato to reincarnate with dirty soil when they are against each other.

The Necromancer Mark is a complete collection of endurance skills of the Vortex Team. However, as a contemporary character, each generation's daughter-in-law is a Whirlpool team member, and Spot is unlikely to know the complete set of this endurance skill, or even know the operation of printing and mediation. It is also a great disadvantage to seal ghosts, and the overall strength should at least be consistent with the enemy. Four generations of Kyubi no Youko's words, only half of Kyubi no Youko died, and three generations of orochimaru sealed orochimaru's hand for a long time, which was a seesaw battle. Referring to the overall strength of Spot, it seems that even Naruto or Sasuke Uchiha may not have played Spot alone.
