Water Release: Mystic River

This is Tenchi Sarutobi's most powerful technique, in which he employs a hundred clones and a teleportation formula in order to create a gigantic water filled pyramid.

Overview
After weaving the hand signs, Tenchi creates a hundred water clones which form the base of pyramid. After the pyramid is created, the clones fill it with water  and move it towards Tenchi's opponent with immense speed. If someone gets caught inside the pyramid, it is teleported via the Reverse Summoning Technique to the bottom of a river or an ocean, to be left there to drown.

Drawbacks
The biggest weakness of this technique is that it can be stopped by having any of the one hundred clones dispelled. However, this should be done before the pyramid starts to move. Also, Tenchi's chakra is left almost depleted after creating the clones.
