Kirito realized that the ability of his eyes was thanks to Lucia. Because when Kirito was experimenting, Lucia suddenly rushed over and let Kirito know the result.
At that time, Kirito was concentrating on the front. He thought that the hidden ability of his eyes was also an offensive ability.
That's why he kept staring at the target, hoping to cause damage, but there was no result.
Lucia saw him standing there motionless from a distance, so she naturally wanted to go forward to see the situation.
However, as soon as she saw Kirito's eyes, her body was completely taken over by Kirito.
Then her mind was also controlled by Kirito. Fortunately, Kirito didn't have any killing intent, so Lucia was only lost in the illusion.
Kirito also noticed Lucia's abnormality and guessed that his ability should be related to Genjutsu.
After all, Kirito had once received a scroll as a reward in the Armory System, so he knew a thing or two about it.
Lucia's current situation is that of a Genjutsu, and from the looks of it, it may be a high-level Genjutsu.
After all, it's a Genjutsu released through the Mangekyou Sharingan, so how can its level be low? The most important thing is that Kirito can also control the illusion at will.
After Lucia was controlled, he also closed his eyes and entered the illusion together with her.
The scene here is exactly the same as Soul Garden, but the difference is that there is no one here.
Except for Lucia who just entered here, and Kirito who came in later, there are only the two of them in this environment.
Lucia didn't understand what was going on, but suddenly her body couldn't move, and then everyone else disappeared.
This kind of thing is still a bit scary for a little girl, but fortunately, Kirito also came in, otherwise, Lucia would panic.
Lucia's first reaction when she saw Kirito was not to go forward, but to hurriedly retreat, keeping a distance and being very vigilant.
Kirito was also taken aback when he saw this, but he immediately smiled. It seems that his sister has grown up, and is no longer the silly child from before.
Kirito was afraid that Lucia would do something extreme, so he directly removed this environment.
The consciousness of the two returned to reality again. After Lucia's consciousness recovered, the first thing she did was to immediately look around.
But the scene this time was the same as before, everyone was still there, and Kirito was standing in front of her.
"Brother Kirito, I think I was controlled by someone just now." Lucia knew that what she just experienced was definitely not an illusion.
And in front of her was Kirito, whom she relied on the most, so she naturally had to tell Kirito first when something like this happened, so that Kirito could be on guard.
But after hearing Lucia's words, Kirito's face was full of smiles, which made Lucia a bit angry.
It was clearly a dangerous moment, but she didn't expect Kirito to be so unreliable. Not only did he not immediately become vigilant, but he also smiled at her.
Kirito saw the expression in Lucia's eyes, so he smiled and said to Lucia, "The one who controlled you just now was me."
"You?
Why are you scaring me? "Lucia said and raised her small fist to hit Kirito.
Kirito didn't dodge, but he just let Lucia hit his chest. It didn't hurt anyway, and Lucia could vent her anger.
In the end, Lucia couldn't really use her strength. After all, Kirito was like Sister Makoto Hikari, caring for her in every possible way.
Seeing that her small fist didn't have any effect, Lucia could only roll her eyes at Kirito and then turn her head away.
She used this method to express her dissatisfaction, and Kirito only smiled even more because Lucia was really cute.
Kirito patted Lucia's head from behind and said to her, "You really can't blame me just now. You came over on your own."
Lucia was unhappy when she heard Kirito's words. She turned her head again and pushed Kirito's hand away.
"Hmph!"
Lucia wanted to say something, but when she thought about it, she did come over on her own, so she didn't say anything.
Kirito continued to explain, "I was training my skills, and you just happened to come over, so I affected you."
"I wanted to talk to you in the illusion space I created, but I saw that you were quite scared, so I canceled the illusion space."
Lucia heard and said loudly, "You know that I'm scared? Is there a brother like you who teases his sister like this?"
Kirito couldn't refute Lucia's words, so he could only look at Lucia with a dry smile.
"I'm sorry, it's your brother's fault." Kirito put his hand on Lucia's head again and rubbed her hair.
"That's more like it. If you do something wrong, you have to take the initiative to admit it." Lucia showed a satisfied smile and then strode away.
She originally had something to do, but when she saw Tonto standing there, she wanted to come over and take a look.
Fortunately, Rukia came over to check on him. Otherwise, Kirito wouldn't have known what he was capable of.
Now that he knows that Mangekyou Sharingan has the ability to create an environment, it's easy to do. Kirito wants to study in depth in this direction.
However, he naturally can't choose to experiment on other people, so he chose to experiment on some small animals, which is safer.
Even if he can't control the illusion space well and causes damage to the brain of the target, there's not much risk.
The experimental target is the small white rabbit Kirito caught from the mountain. The rabbit's words are quite obedient, so it's convenient for Kirito to experiment.
Therefore, there is a situation of red eyes against red eyes. Kirito's Mangekyou Sharingan is red, and the rabbit's eyes are red.
After repeated experiments, Kirito came to a conclusion that his Mangekyou Sharingan can not only bring creatures into the environment, but also control the minds of some weak creatures.
For example, Kirito can completely control the behavior of these rabbits by using Kirito's Tsukuyomi.
In order to be more sure of the accuracy of this level of Tsukuyomi, Kirito decided to find some stronger animals as his experimental targets.
Because of Kirito's move, the nearest hill to Nightmare Soul Society suffered. All kinds of animals were tested by Kirito.
First, he started with rabbits, then a bigger fox, then a bigger wild boar, then a deer, a tiger, and all the animals here became Kirito's experimental targets.
