The Blackroot Technique is an incredibly deadly technique utilized by Jinwei Senju. After building Wood Release chakra in his hand and preforming the Ram hand seal, Jinwei will proceed to jab the target piercing their body. In doing so black root-like manifestations will appear spreading throughout the target's body. The black roots that are created immediately merge with the target's body and can be seen through their skin as clear as day.
The roots themselves are incredibly deadly as they are very poisonous and thorned. As they move through the target's body they feel a great deal of unimaginable pain because of the thorns tearing their insides up as they move throughout their body. Not only that, but the roots are incredibly poisonous and infect the target's bloodstream with a deadly toxin that causes immediate paralysis upon entering the target's body and aggravates the nerve endings drastically increasing the pain that the target undergoes. While all this happening the roots also quickly drain the target of their chakra and channel it to the user.
Death by this technique usually results either from the poison eventually paralyzing the target's ability to breath which takes about five minutes, the target dying from the excruciating pain of the thorns ripping their way through their body which may cut up an major artery, or their chakra being completely sapped. Either way this technique is one that none have survived.
