The Underworld Transfer Jutsu

is episode 304 of the Naruto: Shippūden anime.

Summary
As Neji, Shikamaru, Chōji, Kiba, and Akamaru regroup to assess their situation, on the other side their friends frantically try to figure out what is wrong with them. Realising that they were all still alive but left in a form of suspended animation with weak pulses and lethargic chakra flow, Shino and Ino do what they can to keep their comrades' chakra flowing, while requesting a word be sent to HQ about the situation. Meanwhile within the barrier erected by the Sound Four, the Konoha-nin battle it out once again for their lives. News soon reached Ino and Shino from Inoichi that their comrades were in something that he likened to a genjutsu-like state and that the only way to save them was if they were able to locate and recall their souls somehow as not even the sensory barrier at HQ was able to locate their souls. Elsewhere as Naruto rushes towards his friends' location, he encounters a group of shinobi, and takes out a transformed White Zetsu Army clone. After affirming that there were no more enemies in the group, Naruto moves on as there were no shinobi from the Communications Team there. Despite the fact, however, that the Konoha-nin seem to have the upper hand in their battle against the Sound Four, their enemies regroup and tell them that their efforts were futile against immortals and then informs them that even if somehow they were defeated, there was no escaping from the barrier; leaving the Konoha-nin with two options: die by their hands or have their bodies in the real world eventually give out, and die.

Trivia
