"I have a mission to complete right now. Follow my Shadow Clone first; he'll make arrangements for you."
Gojo Yoru teleported with Konan into a hollow inside a large tree in the Land of Fire. He then created a Shadow Clone, took out a kunai, placed it in Konan's hand, and instructed her, "You must keep this kunai on you at all times.

The teleportation principle of this technique was somewhat similar to the Summoning Technique.
As long as one could sense the Flying Thunder God Seal, regardless of distance, the consumption was fixed—as long as they were not teleporting someone else or transferring an object of astonishing size and mass.
If the consumption had been calculated by distance, then forget Gojo Yoru's tiny amount of Space-Time Chakra—even if all his ordinary Chakra were added together, it would have been drained before he even left the Land of Fire.
