Why is Killer Bee still alive?


I just want to ask, in Naruto Shipuden when Madara extracted all the Tailed
Beast by using the [Gedo
Statue](http://naruto.wikia.com/wiki/Demonic_Statue_of_the_Outer_Path). It is
said that when the tailed beast is removed from a Jinjuriki the Jinjuriki will
die.

I just want to ask, why was killer bee not dead and was able to have a dream
under the infinite tsukoyumi. How is it possible?




According to this [link](http://naruto.wikia.com/wiki/Gy%C5%ABki)

> Madara then proceeded to chain them up and prepared to remove Yang-Kurama

> letting B survive through the chakra within it.**

So in short he was having chakra worth of one tentacle which was cut off from
Gyūki and just because of this he was able to survive.
