Everything was set and Kirito was just waiting for the enemies to come under the range of his trap.
"Alright, I guess that's pretty close enough." Kirito thought and decided to activate his trap.
This particular trap is 1 of the 3 traps he set up in the field. That was all he was able to do before the army came here.
Honestly, less than a week's time was not enough and he was glad that he was even able to plot 3 different ways to kill the enemies by that time.
The trap was simple. He planned to use the same Genjutsu technique which Mito taught him. " The Dark Eclipse".
Once set up, it starts to mess up with others' minds and makes their movements restricted. Now to be honest. doing something like this can give him an advantage but it's not an offensive technique.
And being able to perform his technique on this big of an army is virtually impossible.
Or is it. ?
There was a sly smile on Kirito's face.
"Uzumaki Style, Large Scale Barrier" Kirito shouted and with that said. A huge barrier which he already planned to erect.
At each point of the barrier was standing a clone to maintain the barrier. Honestly performing this big of a barrier on this large scale is not possible. Even for someone like Hashirama. This is impractical.
But Kirito had a plan.
Uzumaki barrier style which he learned from Mito is not that power consuming and only consumes a lot of chakra when holding back powerful force. In easier terms, it only consumes enough chakra it needed to block any kind of thing going pass through it. Even air.
When only stopping something as weak as air blow. It consumes very little chakra while if someone were to attack the barrier with let's say rasengan or Chidori then the chakra consumption would go higher.
Kirito was not planning to stop the movement of the army with this anyway. That would be foolish to do. What he was stopping was air.
The moment the huge barrier was erected it almost looked like someone erected a huge wall around Uzu to keep out the Titans.
The real fun started. All the enemy shinobi started to notice a sudden shift in their chakra. Like something was disturbing its flow.
But there was no Genjutsu yet.
What was happening was that they were inhaling the special Chakra Malfunctioning Gas by Kirito. In his free time, he ended up making a much stronger variation of this gas by condensing the amount of chakra he infuses in the gas. He then made many small gas-release seals and shattered them around the place.
The Gas is still harmless but it acts much faster. The Barrier perfectly stopped any gas from leaking outside and any air from outside from interfering.
Become of the colourless and odourless nature of the gas, no one can understand what was really going on. But everyone started to face trouble controlling their chakra.
And what happens when someone's chakra control is not good? They are prone to Genjutsu attacks.
Kirito after seeing that phase one of the attack is completed. He smirked and then directly went for phase 2.
"Uzumaki Style, Dark Eclipse" Kirito from his place from hand seals and activated the seal he placed in the barrier.
Usually putting multiple people in Genjutsu like this is hard. Putting a whole army under a Genjutsu is downright impossible even for someone like Itachi Uchiha and Yakumo Kurama.
But that is because the caster has to fight all those people's will and disturbs their Chakra control.
Here though, their chakra control is already at rock bottom.
The trick worked like a charm and the entire army really fell under Kirito's Genjutsu.
At first, they were only facing problems in breathing and controlling their chakra. Because of the concentrated nature of the gas. They were also suffering from severe headaches as well. But Now they could not even see anything. Their bodies were not under their control.
All of them looked like tadpoles jumping from one place to another because they were not able to control their movement.
"Phase two complete," Kirito said and there was a smile on his face.
"Now time for the final phase," Kirito thought.
Although the combination of the technique is good it's still not lethal. Kirito had to add a little more to actually kill them all.
This little something is fire. Usually, a normal fire attack is not going to work. But here, when these shinobi can't even move the way they want to. There is no way they can escape fire or try a water-style jutsu to stop the fire.
But it will take a huge amount of chakra to make a fire strong enough to affect them right. Well yes, but he had that cover.
He already rigs the place with oil. The kind which catches fire quickly. The land of Whirlpool is a natural deposit of oil. It was not hard for Kirito to get it. All he needs is to light it up.
So with that, he formed hand signs.
The seal placed by him caught fire. No exploding either. Just caught fire. A small fire which an in-built feature of a seal when the user wants to terminate its use.
He hid oil in the ground, Kirito was very sneaky in hiding it with a wide range earth style techniques. Mostly a thin layer of dust which does not let others know that they are walking on top of an oiled spread land. Quickly caught fire and started burning.
It started small but later it was like someone summon the lava from beneath the surface of the earth. A true hell on earth.
