Why do four generations of Naruto use ghosts to seal it? Is there no other way?

Namikaze Minato, the fourth generation of Naruto, is very popular. It is also very touching that he used his life to show the ghost that sealed Kyubi no Youko. But with the continuous development of the plot, even the powerful Kyubi no Youko has become the plaything of many ninjas. Therefore, according to Huo Ying's early setting, many people have to rely on some special means to suppress it, but Namikaze Minato can only use sealing, and macro strategic considerations (plot needs) leave Namikaze Minato with no choice, as follows.

As we all know, at that time, Kyubi no Youko was controlled by Saringen and fell into a state of violence. If it cannot be solved in the shortest time, it will inevitably bring irreparable losses to Konoha. Therefore, four generations of Huo Ying are desperate to solve it in the shortest time, which is his trademark skill. In addition, there should be other ninja skills, such as seal ninja, ghost seal four red Yang array, Long Mai seal and contract seal.

Kyubi no Youko has a Bijyudama, Watergate has a spiral pill, and movie-level fighting looks cool. The price is the lives of civilians. Without defense, civilians in chakra are the victims, and the fighting is getting fiercer and fiercer, even some ninjas are not spared. A protracted war against bijuu and Kyubi no Youko. Judging from Jiusinai's life experience, she belongs to the kind of orphan of Konoha. No one can seal Kyubi no Youko's seal except her. Besides, she was too weak to print with a seal. These are the objective conditions for four generations to use the ghost seal.

Four generations of Muye Hermit Village are so fierce. Why do you want to seal it with ghosts? Is it really because there is no other way to defeat Kyubi no Youko? "Day One" didn't think so. Four generations of chakra had many other ideas. In addition, before the formal war with Kyubi no Youko, Namikaze Minato used Raytheon to remove the bijuu bomb in Kyubi no Youko. You can imagine how much chakra was consumed. So facing Kyubi no Youko, you may be a little tired.
