Gu Qingfeng turned and left the Eye Demon’s prison.

However, he did not go to the next cell immediately, but started to study pupil techniques and hallucinations first.

I just used it briefly and don't know the specific details yet.

So he carefully felt the information about the hallucinations in his mind.

After a stick of incense, a hint of surprise flashed across Gu Qingfeng's eyes.

This pupil technique and hallucination is really a powerful skill!

It actually has two functions: controlling and creating illusions.

Control means that the caster can control the personal actions of the person being cast. Just like when Gu Qingfeng asked the Eye Demon to kneel down just now, the Eye Demon's body knelt down without any control.

Creating an illusion means that the caster can make the person being cast fall into any illusion according to his or her wishes. What the illusion looks like depends entirely on how the caster constructs it.

However, the disadvantage of Vision is that it can only be activated when the person is looking at you.

And the opponent's soul power cannot be higher than yours, otherwise the effect will be greatly reduced or even ineffective.

In other words, the strength of the illusion depends on how big the gap is between the soul power of the caster and the soul power of the victim. The bigger the gap, the stronger the effect of the illusion.

Although there are obvious flaws, Gu Qingfeng is still very satisfied.

After all, this is a growth skill. It is different from Copper Skin and Iron Bones. Copper Skin and Iron Bones do not have growth potential. The defense power is what it should be and will not increase with the increase of one's own strength.

But hallucination is indeed a skill that increases with the user's soul power!

Gu Qingfeng roughly estimated that with his current soul power, he should have no problem using it to activate illusions against warriors in the Qi Gathering Realm, but it is hard to say whether he can fight against warriors in the Inner Qi Realm.

After all, Gu Qingfeng is only a warrior at the third level of the Qi Gathering Realm now, and it is still a long way to go before he can be promoted to the Inner Qi Realm. Naturally, he cannot estimate how strong a warrior in the Inner Qi Realm is.

As far as Gu Qingfeng knows, martial arts are divided into five major realms: Qi Gathering Realm, Internal Qi Realm, True Qi Realm, Gang Qi Realm, and Innate Realm (Grandmaster)!

These five realms correspond to the five levels of demon exorcists in the Demon Suppression Bureau: apprentice demon exorcist, yellow-level demon exorcist, black-level demon exorcist, earth-level demon exorcist, and heaven-level demon exorcist.

Each major realm of martial arts is divided into nine minor realms.

That is, from one to the ninth heaven, with nine being the extreme. Only after reaching the ninth heaven of the current realm can one break through and advance to the next realm.

Gu Qingfeng is currently at the third level of the Qi Gathering Realm, and is still four, five, six, seven, eight, or nine levels away from the Inner Qi Realm.

The Qi Gathering Realm, as the name suggests, is to condense the vital energy of heaven and earth within the body. If the human body is compared to a sponge, the vital energy of heaven and earth is the water vapor in the air. The sponge absorbs water vapor and becomes wet little by little. When the sponge is completely wet, it means that the body is full of vital energy. At this time, it can be considered the peak of the Qi Gathering Realm.

Although Gu Qingfeng's realm is low, when it comes to combat power, he dares to say that even a warrior at the ninth level of Qi Gathering is not his opponent.

First of all, the copper skin, iron bones and the enlarged iron cloth shirt cannot be broken by the Qi Gathering Realm. There is no magic in this stage of Qi Gathering Realm, it just continuously accumulates the vitality of heaven and earth, passively strengthens the body, increases strength, endurance and so on.

But no matter how strong you are or how healthy you are, you are still a mortal. Can one punch break steel?

Obviously not.

Therefore, just based on this point, Gu Qingfeng is already invincible.

Secondly, there is the powerful weapon Vision, needless to say.

Of course, these are secondary, the most important thing is the system!

It has only been two days and Gu Qingfeng, a loser at the third level of Qi Gathering Realm, has become invincible among his peers. What if a few more days pass?

What if Gu Qingfeng cleared the entire third level of the Demon Suppression Prison?

At that time, even if he faced a heavenly demon slayer, the outcome would be uncertain.

The future is promising!

Gu Qingfeng walked towards the next cell with a vision for the future.

He stopped and raised his hand to knock on the door politely.

However, before he could knock on the door, an old voice suddenly came from the prison.

"Young man, come here."

"Oh, so proactive?"

Gu Qingfeng grinned and opened the small window. This time he was mentally prepared in case something suddenly appeared in the small window and startled him.

However, nothing scary happened.

When Gu Qingfeng looked over, he saw an old, white-haired, and kind-hearted man imprisoned in the cell.

When the old man saw Gu Qingfeng, he smiled kindly.

"Young man, are you here to get materials for the talisman as well?"

The materials for the talisman! ?

Gu Qingfeng was slightly stunned, not understanding what it meant.

The old man continued slowly, "It seems that your Demon Suppression Division has been a bit tight on the war recently. I remember the last time I came to get materials was half a month ago. I didn't expect that they would run out so quickly."

After the old man finished speaking, he reached into the wide robe and seemed to pull it very hard. A hint of pain flashed across his kind face.

"Here you go, young man."

The old man took out a black object from his robe and was about to throw it out of the small window.

Gu Qingfeng was still confused at this time. What was going on? Giving gifts as soon as they met?

However, he was very skilled and courageous, so he immediately reached his hand through the small window to receive the gift.

The old man was stunned when he saw his rash behavior.

???

Is this person new here? A greenhorn?

The old man had lived for hundreds of years and considered himself knowledgeable, but he had never seen such a green-headed demon slayer.

Reach your hand into the prison where demons are held?

This feeling is like going to the zoo and feeding the tiger through the cage. It would be fine if you didn't just throw the food in, but you actually reached into the cage with the food in your hand to feed the tiger.

This is because they are afraid that the tiger will not have enough food!
