Serpiente Cero

Name:
Serpiente Cero
Requirements:
Sie needs to be in his second Ressuricion
Description:
From the mouth of his all eight heads he charges a huge black and red Cero when shot it looks like a snake and can be guided to hit the opponent. As soon as the blast is fired Sie will leave his second released form and revert back to his Arrancar form. Can control this Cero until impact or something breaks his concentration, when his concentration is broke the blast keeps moving in the direction it was heading until it hits something. the blast it self is about 30 feet in length and about 5 feet in width.

so how long do you have control over this serpentine cero, like how long can you manipulate its movement? also i would like a description of HOW huge it is please ^^

done sorry it took so long
