You waited for you sensei in as you were instructed to do. The day was very young in the forest of the unnamed land which you were present.
"You, what is your name?" you heard the voice of a man speak from behind, addressing you.
You'd turn to see a man wearing a long black robe with a large collar and black cloves. He had black hair tied back into a ponytail and the back of his robe, though not visible to you, possessed the Uchiha insignia on it. His eyes were crimson baring the Sharingan in an intimidating scowl looking directly at you.
Genjutsu is a type of fighting while capturing a opponent in a illusion making him thinking a lot of things, the user captures a opponent in a Genjutsu by channeling chakra to him, making his chakra flow irregularly and affecting him mentally and in some Genjutsus physically, also there are some Genjutsus that damage the 5 senses of a opponent, there are types of Genjutsu that scare the opponent with his greatest fear, change the terrain, capture/crush/immobilize/constrict/restrict the opponent and there is a type that makes the other things living and those things attack the opponent.Ieyasu stares for a moment at you before walking past you toward a tree and leaning against it. As he passed you he spoke
"Tell me what you know about genjutsu..." Ieyasu asked plainly
You asked me how to release a Genjutsu, rite ?"Hmm, you seem to have a general grasp of the idea but I didn't hear you say anything about how to fight genjutsu. Tell me what you know about combating against the illusion arts?"
Ohh yeah, your comrade can channel his chakra to you to help break free from the Genjutsu"You're missing one, tell me how having a comrade by your side can help you in releasing a genjutsu."
Okay i got it Sensei, i'm ready now"The chakra insertion method only needs to be chakra that's used externally that forces out the foreign chakra causing the genjutsu. It doesn't matter if it's yours from a clone or anything else. As long as it's separate from the chakra being affected by the genjutsu it doesn't matter. So it would make sense for clones to be able to be able to release you from an illusion."
"Good one last thing about breaking.
Natural Energy
Curse Seal of Heaven/Earth
Bijuu Chakra
Absorption Jutsu
How are all of these areas similar in their ability to break genjutsu and what method do they fall under. If you're unsure, just take an estimated guess, these aren't conventional methods that juts anybody can use so it's uncommon knowledge. Nevertheless as a shinobi you need to be prepared and be intuitive if you are to succeed."
