After Kyubi no Youko of Konoha Village was stripped from Uzumaki Kushina, it was controlled by Uchiha Obito, and Uchiha Obito controlled Kyubi no Youko to push Konoha. Kyubi no Youko, which has been controlled, is raging in Muye Village. Konoha village is facing destruction, Konoha villagers are in danger, and ninjas will suffer a lot of casualties. As the fourth generation of Huo Ying, he must protect Konoha Village, even at the cost of his life.
Uzumaki Kushina, who wants to go with Uzumaki Kushina, has been evacuated from bijuu, and time is running out. Maybe Namikaze Minato, who can't win Uzumaki Kushina alive, wants to go with the old Sinai. After all, he is deeply in love with Jiu Si Nye.
With the strength of four generations of Naruto, Kyubi no Youko's four generations of Naruto impressed the audience most with his space endurance, but these are still used to deal with ninjas, but bijuu, who is huge, obviously can't work hard. The only fatal trick is the spiral pill, which won't last long in front of Kyubi no Youko's huge Chakara. Even if Kyubi no Youko is killed, bijuu will be born again, and the original three tails will be born again. When Kyubi no Youko comes back to life, Konoha should still be there.
The blockade of Kyubi no Youko is not only to prevent Kyubi no Youko from causing more damage to Konoha. From a strategic point of view, Konoha, as a powerful endurance village, cannot be justified without the reserve of human strength. Moreover, sealing half of Kyubi no Youko's chakra to Naruto can be used by Naruto in the future, and even taken care of in the village as a human force. In any case, this is the right direction. Only after Kyubi no Youko was sealed to Naruto, the villagers regarded Naruto as an alien.
In order to give Naruto a trump card in every village, Kyubi no Youko Fox is the trump card of Konoha Village, and Vortex Nine can no longer live as a human pillar. Now only Naruto can become a pillar, and there is no other way. Naruto can only seal half of Kyubi no Youko in his body.
In fact, bijuu can't be killed, and bijuu is the aggregation of evil energy. Even the God of Endurance and Senju Hashirama can't be killed, so bijuu can only be sealed, so four generations of Huo Ying can't kill Kyubi no Youko.
Kishimoto Masashi set this on purpose. After all, the plot needs to start from the high wind, and Naruto's strength is also rapidly improving. Although there is a protagonist aura, it is too monotonous to rely on the protagonist aura all the time. Kyubi no Youko has played a very good role in paving the way, which will make people feel more acceptable.
