The Space–Time Path is negative space that can swallow everything around it. It can only be summoned by a member of the royal family in the chamber where the Book of Gelel describes, by offering a small amount of the member's blood, in order to destroy the Vein of Gelel, but the summoner will also die, as nothing that has been sucked into the void has ever come back out alive. Temujin summoned the Space–Time Path to seal the Vein of Gelel when Haido's defeat accidentally destroyed the key and causing the vein to go out of control. He was ready to accept his death, but Naruto saved him from being sucked in as well by using a chain of shadow clones.
