I'm implying the area which is turned into a fluid like substance no longer effect Kisame.If there's no force how could it trap the Juubi for some time
And either way we don't know if he can use that on other people's chakra and if the transformation is instatanious
No implications it woulnd't. The sandwich itself isn't instantaneous, so Kisame can just stand in its near proximity while in contact with it to turn it into fluid. Anyways, it seems obvious that when Kisame is literally swimming through the ground like its fluid the ground that is on his 'road' is instantly being turned to liquid.
