Bloodline Drain Technique

First, the user draws blood from his victim's dead body and ingest it. Then, they draw Jashin's symbol on the ground in blood and places the body in the centre. After placing in their hand on the victim's body, the body is then decomposed in a red flash as the symbol glows, draining them of all Kekkei Genkai. The user not only obtains their kekkei genkai, but knowledge of almost every technique the victim used with that particular skill.
