As the cavern formed, Zhoom was quick to react, making an opening to keep sight of the opponent. As it opens, there was no sign of the man's presences. Zhoom assumed that the man had gone underground. He then moves back to mid-range (since you moved to short then i moved to long so its mid o_o). He then perform a single hand seal as a hole appears within the ground as the man is sucked underground, due to already being in the earth. Zhoom cancels the technique as the hole closes, causing the man to be stuck underneath forever.
(Doton: Arijigoku no Jutsu) - Earth Release: Antlion Technique
Rank: B
Type: Offense
Range: Mid/Long
Chakra Cost: 20
Damage Points: 40
Description: The user performs the Ram hand seal and causes causes the ground and everything on and around it to be sucked in towards the middle of a large pit, much like the method an antlion uses to catch prey. Upon being dragged to the centre, the victim will then be sucked underground. There the victim, depending on how deep the user makes them sink, will be trapped and/or suffocated. The range of the pit is determined by how much chakra is put into the technique.
