Reciting a magic spell, the man with a sharp mouth and monkey cheeks grinned, showing a desperate and crazy smile.

"boom--!"

A deafening roar came from the dim space, and the entire cave was shaking violently. The stalactites on the roof of the cave were shattered and fell to the ground like raindrops.

With his long icy blue hair dancing in the wind, Willett stepped back sharply, raised his hand, and a white ice flower condensed from ice elements appeared in front of him.

The diameter of the ice flower is about six meters, and it withstood the strong shock wave caused by the explosion in a short time.

The ice covering the ground was shattered one after another, making a crashing sound, and evaporated into pieces of white water vapor in the high temperature of the explosion...

"call--"

Willett raised one hand and waved forward gently, and a strong wind mixed with hundreds of snowflakes suddenly blew away the black and green smoke that filled the air after the explosion.

The figure in the smoke reveals its true form.

What appeared in Willet's sight was no longer the thin potion appraiser with a pointed mouth and monkey cheeks. Instead, he was a complete monster.

The monster's body is covered with black scales, with a pair of horns emitting red light on its head, and around its blood-red eyes are twisted black stripes like poisonous snakes.

Purple blood vessels appeared on the surface of the skin, squirming and covering the monster's entire face.

Dark green fishy mucus stretched out long threads from the sharp fangs, and the ferocious black claws reflected a cold and hard luster like metal.

Like a demon from hell.

The potion appraiser laughed three times in a hoarse and harsh voice: "Hahaha! I am the real monster... fear me!"

"Ugly."

The girl with the strange eyes had a face as cold as frost. She stretched out the index finger of her left hand and gently tapped it forward. Hundreds of ice arrows with a cold light appeared out of thin air.

The moment Villit retracted his fingers, they all shot out, piercing the air, making a dense and harsh scream, falling on the red-horned monster like a heavy rain and wind.

Hundreds of sharp ice arrows collided with the monster's pitch-black scales, and a large area of ​​golden sparks was created!

When the tip of each ice arrow comes into contact with the black scales, it will emit a scalp-numbing roar.

In the dark cave, there were hundreds of explosions.

The red-horned monster stretched out its claws to block its face, and used its black scales to defend itself against all ice arrow attacks. Then it suddenly stepped forward, its blood-red eyes shooting out a sharp and ruthless gaze.

The appraiser who turned into a monster laughed heartily: "Hahaha, so what if you're prettier than me? You're still going to die in my hands!"

Before he finished speaking, the red-horned monster took another step, and a deep pit was dug out of the ground made of hard rock by its ferocious feet carrying huge power!

The monster's speed suddenly increased, like an exploding cannonball, rushing towards the petite ice girl in front!

Because he has released half of his control over his body, Willett now shares the same body with the Seven-Xuan Ice Phoenix Bird.

"He has lost all humanity and has become a lowly and ugly scum. If you don't kill him now, we will be the ones who die!"

The voice in my head is strange and cold, and the monster in my body is trying to gain more control over my body.

Willett wanted to avoid the frontal attack from the red-horned monster, but the Seven-Xuan Ice Phoenix Bird refused to dodge.

As the king of the demon clan, Qixuan Ice Phoenix Bird felt that his demon character was insulted by hiding in front of a nondescript monster.

"Give me all control of your body, and I can kill him easily!" The voice in his head was full of desire, trying to overwhelm Willet's will.

Due to the influence of the monster inside him, it was too late to dodge now.

Willett raised her bloodless left hand and made a gesture of holding it forward. A ray of ice-blue light shot out from the palm of her hand and instantly turned into a blue shadow with a diameter of dozens of meters.

The blue phantom sprinted forward, and at a speed faster than a cannonball, she grabbed the red-horned monster that was charging towards her. Violet's white fingers were slightly bent, making an action like throwing away garbage.

The red-horned monster, controlled by the blue shadow, involuntarily left the ground and was instantly thrown hundreds of meters away, slamming into the hard stone wall of the cave.

"Rumble...!"

The ground shook violently, and the stone wall could not withstand the huge momentum. It shattered into hundreds of large rocks with a bang, falling to the ground, revealing the space on the other side of the wall.

Slowly getting up from the ground, the red-horned monster shook its dizzy head.

He has always been very confident in his demonic poison, not to mention that the demonic poison planted in his body this time is a demonic poison seed containing demonic blood... Could it be that the ice and snow demon is stronger than himself with demonic blood?

How is this possible!

"You are too weak." At this moment, a cold and ruthless voice suddenly sounded in the appraiser's mind, "If you really want to defeat her... how about making a deal?"

"...Who are you? What deal?!" The red-horned monster looked around in panic. Except for him and Willet, there was no sign of anyone in the cave.

"who I am?"

As if hearing a big joke, the mysterious voice sneered and asked, "You used my blood to make a potion, and you asked me who I am? Haven't you always longed to have power like me?"

As if realizing something, the red-horned monster's blood-red eyes widened, and its whole body trembled uncontrollably.

"You...you, you are-"

The cold voice sneered and replied in a low tone: "I am the son of the devil, and I am in your body now~ How about it? Do you want me to help you kill her?"

"The price...what's the price?" the red-horned monster asked the voice in his head. He was excited and frightened.

The Son of the Devil is a real devil, but he was killed by a righteous wizard hundreds of years ago.

He tried every means to get the blood of the devil's son, but he didn't expect that the real devil would be resurrected in his body...

Thinking of the arrogant "Ice and Snow Demon" being trampled under his feet and begging for mercy.

The heart of the red-horned monster is about to stir.

"Give your soul to me and become my food. How about that?"

The son of the devil continued to induce, and his tone changed from cold to cordial, "Anyway, you can't defeat her with your current ability. You might as well let me help you solve this trouble."

"Or are you so cowardly that you are willing to be killed?" The voice of the son of the devil was cruel and cold, and he broke the reality with a few words, "You have become a monster, and you can no longer become a human being."

In the magical world, there is a theory of reincarnation, and the soul body can indeed maintain a clear consciousness after leaving the body.

If you sell your soul to the devil, it will be very painful, whether your soul is swallowed by the devil or you remain a slave to the devil.

The potion appraiser turned into a monster, but he still retained the last trace of sanity in his heart.

The nature of the appraiser is to be afraid of death, very afraid of death.

When he was in the gap world, even though he knew that Alice and the others were fighting the white suit puppets, he had no intention of interfering and chose to leave Opslet without hesitation.

Originally, he wanted to set up a scheme to turn both Willet and Alice into monsters and imprison them in the underground caves of the Forbidden Land forever.

When the magic poison in the academy breaks out, he can take advantage of the chaos to escape from Credo.

But the plan failed to keep up with the change, and the secretive magic guild leader turned out to be an ice demon.

Even if he makes the antidote, he is still a murderer who killed the factory director.

This is an inescapable fact.

Even if he manages to escape Credo, the Magic Alliance will send people all over the world to hunt him down.

He is not willing to let the two brats who ruined his good deeds succeed!

After all, exchanging one person's life for the lives of so many people is very cost-effective no matter how you think about it.

But the plan couldn't keep up with the changes. Even though I became stronger through the magic poison, I couldn't defeat the terrible ice and snow demon.

It will just be thrown around like garbage...

The frustration was like a raging tide. While it depressed him, it also aroused unwillingness and anger in his heart.

The opportunity is right in front of him now, even if the consequences are serious, but he has hurt so many people with the magic poison, and he is already full of sins.

The last trace of reason in his heart was destroyed by the strong wave of resentment, and darkness swept over him. He heard himself spit out three words in a dry and trembling voice:

"...I do."

The next moment these three words were spoken, the cold voice of the Son of the Devil slowly sounded:

"Start now, the transaction takes effect!"

"Ahhhhhh!"

Intense pain swept through the whole body, and the red-horned monster opened its mouth uncontrollably and screamed.

The blood flowing in every blood vessel in the body was like volcanic lava, causing it to convulse all over.

The body of the red-horned monster has become stronger at a speed visible to the naked eye. Through a layer of black scales, you can clearly see the outline of the bulging muscles, the exaggerated biceps, and the blood-red eyes that seem to be burning.

The dark and ferocious claws turned dark red, dazzling red light shot out from the gaps in the scales, and blood-red flames burned on the red horns on the head.

The temperature inside the cave increased rapidly. The ice on the stalactites on the roof of the cave melted into water and dripped downward. When it was about to come into contact with the pair of burning blood-red horns, it was instantly evaporated into white steam...

The facial skin of the red-horned monster turned completely black, and the raised blood vessels glowed faintly with a dark red light.

A pair of demon wings came out from the back, and when the bones were squeezed, they made a "clucking" friction sound, which made people feel numb.

A terrifying and evil aura emanates from the body of the red-horned monster!

The painful monster stretched out its hands, the red wings on its back vibrated, and the corners of its mouth raised, revealing its scarlet teeth. The monster turned around and looked at the magic president with fluttering blue hair. Pure evil and darkness filled its blood-red eyes:

"Now...this body belongs to me, please call me Son of the Devil!"

This is an evil thing from hell. The guy standing in front of her no longer looks like a nondescript monster, but a real devil.
To be continued...
