Chibaku Tensei (chapter)

Summary
Over Konan's objections, Nagato uses Chibaku Tensei through the Deva Path, further weakening his already frail body. Naruto, in a six-tailed form, is caught in a giant sphere of debris. He enters an eight-tailed form to escape, but even then he has difficulty. Frustrated, Naruto, within his subconscious, cries out for help. The demon fox offers to destroy Naruto's enemies if he lets it go. Naruto prepares to remove the seal keeping the demon fox contained, but is stopped by the Fourth Hokage, who thanks the fox and its bad influence for giving him a chance to see his son.
