I ask why 9 Living things? Wont some chakra crystals would heve been better? As it cld be easily hidden and protected. Its bcos u keep avoiding the fact that chakra need to be generated to maintain, or it will be lost. So sage made sure it wont be lost or go back to Jubi. Plus Biju does not comapre to Mokuton. As Hashi perhaps uses only yang to give life then water and soil to make the plant grow, making them natural trees as their genetic materials and physical forms are gift of nature not Hashi's imagination or yin chakra.
Also where did u read that Jubi's chakra is undestroyable or can not be lost? Minato effectively sealed a good portion away.
BTW Yang chakra is not clan inherited, anyone and everyone can use it if anyone knows how to. hashi just had a greater affinity for it.
Because the Sage raised the Tailed Beasts to be good and helpful... they wasn't evil to begin with. It was the villages who made them turn evil by hunting them down for power.
Like I said a thousand times the sage did the same thing... he used the Yang from the creation of all things Jutsu to give life to the chakra. Hashirama used his Yang chakra to give life to his Mokuton. At the end of the day, it is still chakra.
If the 10 tails chakra could be destroyed he would have done that, instead of sealing it inside himself. This is why he split the chakra up in the first place... Minato sealed the chakra away but it is still alive. It is just trapped for ever.
The Senju clan inherited the Sage's power Yang chakra, which is why they are so proficient in healing etc. The Uchiha clan inherited the Sage's powerful Yin chakra which is why they are so proficient in Genjutsu etc. Why else would they mention this?
Anyway, I really cant be bothered to keep debating this. It seems most people understand where I am coming from anyway.
