Because the comment section feels that Zhu is too powerful after his resurrection, which may make the character too invincible and the plot collapse too quickly, so I will explain it here.
First of all, not all pillars have the ability to penetrate the world.
With this kind of pillar who can directly see ninjutsu at the ninjutsu level and has the ability to learn ninjutsu without any obstacles, he will not be resurrected too soon.
The three breathing methods of Wind (Xia Pillar), Thunder (Snake Pillar), and Earth (Rock Pillar) are relatively difficult to master in the Konoha Ninja School, so they will be resurrected later.
However, those who do not have this kind of penetrating ability (Die Lianyan) must learn to extract chakra and control it from scratch like ninjas. Moreover, because they do not have micro-manipulation ability, they cannot combine breathing methods to absorb nature at the beginning. Energy, that is, senjutsu chakra cannot be extracted, so its strength is limited. You must learn to be transparent.
They only stand out in some aspects of their physical fitness, their affinity for certain attributes is naturally high, and they have rich combat experience. This is what they will definitely have as soon as they are resurrected.
Personally I don't think it's too exaggerated.
Secondly, Giyu selected their genes not based on blood inheritance limits, but on similarity in appearance, so as to retain their original appearance as much as possible, so not everyone will have Naruto's physique like Purgatory.
Third, there is Yiyong himself. He has a very high affinity for the water attribute, which means he is greatly affected by the environment.
His full blow in the sea is powerful enough to destroy the Hokage Building, but in a normal environment the power is only one-third, and it will be even lower in a waterless environment. In short, his strength will fluctuate greatly.
At present, Giyuu's biggest problem is that he can learn ninjutsu without any obstacles, and except for specialized taijutsu experts like Kai, jounin-level taijutsu basically cannot hurt him (because of the dual dynamic vision of transparency + sharingan).
But if he wants to use the breathing method to enter the sage mode, he needs to have much more chakra than he does now (without turning on the kaleidoscope to increase the chakra dramatically), so the growth cycle is not short. I know how big the distance is between a jounin and a kage.
Above, I wish you all happy reading.
