Brainwashing Technique (Earth-8361)

"There is no war within the walls. Here we are safe. Here we are free."

- - A Dai Li agent

Brainwashing was an genjutsu developed by Long Feng that incapacitated any of those who opposed his rule. Utilizing the Dai Li to enforce his will during the Conspiracy of Ba Sing Se as a means to keep Ba Sing Se's citizens from speaking about the Third Shinobi World War, this allowed the Dai Li to alter attitudes, beliefs and mold personalities as they pleased.

History
The technique was cast on Jet following his arrest at Ba Sing Se. After after he claimed Jiraiya and Zuko were Konoha shinobi. After killing a downcast Joo Dee for failing in her duties to keep whispers away, Long Feng personally induced Jet into a hypnotic state by reciting a special phrase. Once Team 7 infiltrated the secret Dai Li base hidden underneath Lake Laogai, they saw a room full of women being placed under the technique by Dai Li agents, all carrying the name "Joo Dee".
