Actually, it doesn't matter what the name of the pupil is, anyway, for Roy, everything is a definition.

Even if necessary, Roy can do it by firing dynamic light waves with a writing wheel eye......

And if you want to see through illusion and not be affected by it, you must have the function of insight and be able to distinguish between reality and fiction.

Then, using blood-red floodlight lines, he drew a five-pointed star pattern in the pupil to distinguish the difference between using the pupil technique and not using the pupil technique.

Demons, of course, are more vivid represented by pentagrams......

Roy named his pupil technique [Nightmare Eye]!

【Nightmare Eyes】

Definition 1: Insight, which can decipher the effects of illusion and distinguish between the real and the unreal.

Definition 2: Fear, the enemy who looks directly into these eyes will have inexplicable fear from the bottom of his heart.

Worried that the soul would not be enough, Roy only made two definitions of this nightmare eye for the time being, definition 1 is naturally set to deal with illusions, but definition 2 is inspired by nightmare demons.

During the time that Roy stayed in the middle abyss, he came into contact with several nightmare demons, this kind of mid-rank demons with demonic horns on their heads, burning flames all over their bodies, and shaped like horses, although they are often used as mounts by some high-ranking demons, but it would be wrong to underestimate them because of this, because these nightmare demons are relatively powerful mid-rank demons in the mid-abyss world.

Through observation, Roy found that the magic growth rate of nightmare demons is generally relatively fast, this is because the demons who write nightmare bloodlines, their magic circuits, will form a special magic that makes people feel fearful, when they use magic to kill enemies, the soul obtained will be larger than usual in size!

Roy had seen the Nightmare Demon Hunt, and compared the souls they harvested with his own, if it was only one or two, it could only be described as a coincidence, but after comparing many times, Roy found that when they hunted the same monsters, the souls they got were indeed larger.

At that time, in order to verify his conjecture, Roy also specially found a nightmare demon as an opponent and fought one, but that one, Roy really didn't win, he found that the longer he fought with the nightmare demon, the more he would retreat in his heart, and he would feel that the nightmare demon in front of him was very powerful and terrifying!

And afterwards, Roy reacted that this fear effect with a strong suggestive effect may be something worth learning from, this fear effect can allow him to gain more negative emotions in the future hunt!

This thought made Roy understand why Alania would chatter and intimidate him with words when he first encountered Alania the Spider Queen, it seems that Alania at that time just wanted to get a better and more fearful soul from him.

And this kind of intimidation is actually not only used by Alania, many demons like to roar loudly at their opponents when fighting, showing their fangs and claws, which is itself an act of intimidation.

The effect of simply using words to intimidate the enemy does not seem to be good, because if you want to use words to make the opponent fearful, you must keep repeating it to have a suggestive effect, and talking too much can sometimes lead to the villain dying from talking too much! The Nightmare Demon's fear effect is much better, silently influencing opponents in battle.

Therefore, when Roy felt that he could borrow the ability of the Nightmare Demon, in fact, the first thing he thought of was to allow himself to obtain a fear force field, which is commonly known as the fear aura, so that as long as he stood there, he could affect the opponent, not to mention, and he could also act on multiple objects at the same time!

But again, the soul currently held may not be enough, such a fear aura effect must be set to the kind of effect that is emitted all the time, and a stop in the crowd can make people feel terrifying and frightened, and the radiation range is small, plus this time Roy still needs to deal with illusions, so in the end, he can only temporarily dispel this idea, and change the range-type aura effect to a one-on-one pupil effect to use it first.

When you have accumulated a sufficient number of souls in the future, it is not too late to make changes.

Of course, the generation of fear is often accompanied by some cranky thoughts, in a sense, this is also a kind of illusion, but he can't create and guide the opponent to imagine what kind of terrifying situation, he can only be cranky by the opponent himself, and then produce a kind of psychology that scares himself.

Roy temporarily defined his pupil nightmare eye into these two attributes, and later when his soul was enough, he would continue to add more powerful abilities.

For example, the ability to see the opponent's magic circuit node, or directly see the opponent's weaknesses, etc., or even like the eye of death, see the opponent's death line, and then cut off the death line, and directly kill the opponent's ability, these abilities, of course, Roy coveted, but in the same way, the more souls are consumed by powerful abilities, so for the time being, they can only be used as goals to work on.

After the setting was completed, Roy thought about it and added a light and shadow effect to the nightmare eyes, so that when Roy used the pupil technique, his eyes would glow with obvious blood-red light, which would make him look more terrifying, thus exacerbating the opponent's fear.

When Roy chose to save the manifestation, he found that the number of souls he currently held was not enough to consume, and he could only complete 75% of the total, so he had no choice but to take the fat tiger to the living area of the flame lizard again to hunt, and after killing more than 200 flame lizards, he finally embodied these nightmare eyes.

There are more than a thousand flame lizard souls, which is almost equivalent to three hundred low-level souls of normal level, but I didn't expect this pupil technique to be quite expensive......

When Roy injected magic into his eyes, a bright pentagram pattern appeared in the depths of his pupils, and at the same time, Roy's demonic eyes also glowed with a terrifying blood-red light!

The fat tiger tilted his head and was looking at his master, but he was startled by Roy's sudden change! Whimpered.

Roy lowered his head and stared closely at the fat tiger in front of him, and the three heads of the fat tiger also looked at Roy's eyes, and after a while, the fat tiger's tail stopped swinging, and subconsciously clamped between his hind legs.

Not only that, but among the three heads of the fat tiger at this time, different pictures appeared.

And these pictures all have a common theme, that is, hunger and cold!

In this self-fantasy dominated by fear, the fat tiger "dreamed" that he was walking in a cold and snowy environment, and the owner was gone, an inexplicable sense of fear invaded the fat tiger, so it spread its legs and ran, trying to find the traces of the owner, it felt that only by staying by the master's side could it relieve its uneasiness...... But it didn't get anything, it didn't encounter any living creatures, not even any plants, it was surrounded by a white expanse!

Time passed, but the surrounding scenery did not change at all, and the fat tiger gradually could not run, and his stomach had long since deflated, and he became skinny, because he had not eaten any food for a whole week, and the owner was still nowhere to be found.

Thinking about it, Fat Tiger suddenly felt so aggrieved, and couldn't help but look up to the sky and shout!

"Whew! (Master you)"

"Woo! (Don't)"

"Wang? (Fat Tiger?) ）”

Roy didn't know what kind of picture appeared in Fat Tiger's mind, he just stared at Fat Tiger for a while, only to find that Fat Tiger first became very uneasy and frightened, and then suddenly, Fat Tiger leaned back on his three heads and wailed with tears in his eyes.

"! What the hell did this kid see? Roy was also taken aback, and quickly withdrew his magic power and woke up Fat Tiger.

The fat tiger came back to his senses and found that the icy environment around him had disappeared and his owner had reappeared in front of him, so he whined and pounced on Roy, licking Roy with three tongues.

"Hey, what's the matter!?" Roy quickly pushed it away, only to find that Fat Tiger had become extremely clingy at this time!

I don't know what it just saw, why it turned out like this......

For a while, Roy also regretted taking the fat tiger for an experiment......

Over the next few days, Roy changed his test subjects, experimenting with the Eye of Nightmares with a Flame Lizard and some of the Median Demons he encountered.

He found that the less intelligent the creatures, the worse the Nightmare Eye's fear effect was, because the more innocent creatures imagined fear, the more simple the imagination of fear, and the Flame Lizard did not even need Roy's Nightmare Eye to exert fear on them, they would run away when they felt the threat of life and death in the face of powerful enemies.

And for creatures with high intelligence, the fear effect of the Nightmare Eye has room to play.

Because after using the pupil technique, Roy's eyes will glow with a blood-colored vision, especially when the head is swung, and there will be a faint trace of light in the air, so it will make the opponent unconsciously look into his eyes, and under this look, it will be affected by the fear effect.

They will passively flash some things that are difficult for them to accept and feel terrible, and for demons, the most terrible thing is nothing more than encountering a powerful opponent, so they will feel that Roy looks terrifying, his strength is very strong, and when he fights, it will inevitably shrink his hands and feet, resulting in the inability to play his strength normally, making Roy even more handy in fighting.

Of course, there are also some demons with high willpower who are difficult to be affected by this fear effect......

Overall, Roy was quite satisfied with the fear effect, because he had verified that the souls, size, and soul power of enemies affected by fear had indeed increased after killing!

This means that in the future, when Roy hunts souls, he can get this fear bonus, so that the soul that originally had 1 soul power becomes 1.1 or even 1.2! In this way, you can slowly accumulate a lot of sand, and when you have enough souls, you can change this fear effect into a range-type aura radiation, and even further strengthen this fear effect.

And as soon as he thought of this, Roy couldn't help but think of a question, in the future, he won't become a fear demon king, right? ?

Well, no, it's hard to say about the Fear Demon King or something, but I'm afraid I'm more like Zeratul and like a star spirit, right......
