[Kotadama illusion arts (rank E): (Progress:60%)
1)Control receptors related to smell and taste through illusion using sound. Sound source: snap of chakra-covered fingers.
2)Control receptors related to hearing through illusion using sound. Sound source: snap of chakra-covered fingers.
Chakra cost is related to power, chakra control, and genjutsu mastery of the enemy.
illusion can be cast on yourself also to enhance your senses or shut them down. Bust the chakra cost is double than when used on the enemy of the same rank.]
Orochimaru came to know that kotadama illusion art deals with the control of receptors for the function of senses.
He read about controlling chemoreceptors and other receptors for controlling senses of smell and touch.
It has many uses like enhancing your nose to smell, changing the taste of an object.
Although it seems useless in combat, it is important. Controlling it will increase the reality of genjutsu by many folds.
When Orochimaru upgraded the KIA to E level the knowledge to control receptors for hearing was introduced. KIA needs a lot of biological knowledge related to receptors and then controlling them according to the method specified in KIA.
Orochimaru can see that the technique is going to take the route to control all senses.
One of the receptors for hearing also is responsible for the balance.
Although he has not progressed in the KIA enough to control receptor for balance fully he has enough mastery to disturb the sense of balance of the enemy.
Orochimaru beheaded the Jashinist who were not able to control their body and were falling forward due to disturbance in their sense of balance
Orochimaru stumbled a little after cutting their heads as this consumed lot of his mental energy.
But he still stood and checked if they were dead or not. After he checked the leader body he was surprised to find that the leader still had life left. So, he inserted kunai in his heart which ended his life.
After checking that they were dead Orochimaru was ready to dispose of the bodies.
As for why not take it to the village.
Although he may get some reward Orochimaru did not want to show that he can defeat chunnin and he has used KIA on them, so it's impossible for him to submit their heads as the Yamanaka can find out about the fight.
Although in anime it was hard but not a big deal for defeating a chunnin at genin level, in this world, every rank has major changes thus it is almost impossible to kill a person with chunnin level physical qualities.
As he took out kunai from the leader's heart he not surprisingly got system messages.
[Reward for killing 2 genins 200]
[Reward for killing 3 chunnin 1500 points, 1500 points bonus for killing higher level enemy]
This was expected by Orochimaru but he never expected the next messages
[Ding! Object necessary for completing a hidden condition is found]
[Do host want to absorb it
Yes. No.]
Orochimaru of course clicked yes.
[Essence of Jashin is absorbed]
[Hidden condition 'Absorb the essence of existence having compatible talent with poison body' has been completed]
[Poison body has changed to cursed poison body]
[Cursed poison body(intermediate)

Poison body:
immunity to poison and if enemy poison you, depending on the intensity of poison the respective healing will take effect
Poison blood(NEW)
Your blood will act as a poison. The intensity of poison depends upon the poisons you have ingested till now.
2)Curse series:
Curse of retribution(NEW)
After activating this skill 20% of damage received by the user in the next 5 second is transferred to the attacker
(essences collected:20%)]
Orochimaru didn't expect that he was able to fulfill the hidden condition for one bloodline talent so early.
Orochimaru also checked other jashinists and the progress bar did only increased by 1%. But he was still happy.
Moreover, the curse of retribution is a pretty strong skill if used properly.
Orochimaru always thought that Jashin was made up of these lunatics. But it seems that he exists.
He really would've started finding and killing jashin and janishists if he was not still a genin.
But Orochimaru didn't contemplate much and maxed chakra controller as he has got enough talent points from this kill.
[Chakra controller (max) :
Chakra controller(lvl max): increase chakra control practice speed and proficiency by 100%.
[New evolutionary paths generating
2 talent jades-
Fuinjutsu controller:(locked)
Medical controller:(locked)
Chakra saver: when performing a jutsu the chakra cost is decreased.]
He immediately bought the chakra saver. Although he only has spin, chakra burst, illusion, and body flicker jutsu now he still felt that chakra is very essential.
Although he will still have more fighting power than all ninjas without chakra his power still faces a decrease without chakra.
[Chakra saver(lvl 1): decrease chakra cost of jutsu by 1%]
Although it seems quite low it's still a thing that many ninjas will kill for. Moreover,r this skill still is lvl 1.
