How did Naruto call Shikamaru and the others during Obito's fight? Alert: This post contains spoilers. If you are not up-to-date to Naruto's manga, don't read it.

At chapter 651 of Naruto's manga, during the fight against Obito, Naruto called Shikamaru, Lee, Ino, Kiba and the others to join the fight and help him:



But what kind of jutsu did Naruto use to call them? Is he using the abilities of Yamanaka's clan or his own Kyuubi's chakra has this kind of power too?
I think the answer can be the combination of the two:


Mind Body Transmission Technique from Yamanaka
And Naruto's Chakra present to them.


My theory is that Ino consistently connecting them using her Mind Body Transmission Technique from the start. And since they have Naruto's chakra, they even share the feeling not just the picture (or the message) they want to convey to everyone. Also I remember on Chapter 645, Naruto is in combined Sage and Kyubbi mode. Naruto's Biju mode is so powerful that he can sense the "dark feeling/hatred" from something or someone.
