Nice. Actually, the purpose of this technique lies in the ability to merge back with the earth and become simply a chakra construct again. With this ability, it can leap through the air, land on something, and then as it merges with the earth it crushes something on a scale which can no longer be called crushing; if you crush something, you imply that there is space there where it is being crushed. What this technique does is push anything caught in its way into a single point in space, completely unmeasurable, in which they will exist, or cease to exist if you look at it that way, in their entirety. The strangest part is, once the serpent has gone all the way underground, there will be nothing left of whatever was underneath it. In addition, if damaged but not destroyed, the snake will re-enter the earth, and then rise again at a different location comprised of new earth. Meaning it is, once again, A-rank (unless the chakra itself in the technique is damaged). Finally, this technique can be used continually as you wish for 3 turns with other techniques performed as you use it, making it VERY versatile overall.
Now, any questions before we move on?
