The Forbidden Magic Laws of a Fallen Princess• Chapter 291

That's right, I'm going to use the Royal Sword Technique, which was originally meant to defeat the Black Dragon God, to defeat Duke Harman, who has now become a demon king. Although the battle is against Duke Harman, who has transformed into a demon king, let's just consider it a small test before eliminating the Black Dragon God. Now, I'm truly lucky to be able to unleash my ultimate technique and experience its power, especially since I've transformed into the Demon King Duke Harman.

"I was originally planning to let that little dragon girl try it, but it seems I don't need to.

It's just right for me, hahahahahaha!!!

"At this moment, his voice became even more muffled than before, and he raised his head and laughed wildly, but his voice was much louder than before.

Perhaps he thinks he's invincible now, and that killing me would be as easy as killing an ant.

Ha, how arrogant!

I'll show you that I, Princess, am not so easily bullied.

Even if I become a demon king, I'll still be my defeated foe, someone I can trample under my feet.

Because my familiar, Momoko Miriam, is a true demon king.

However, in the next moment, he suddenly swooped down and rushed directly in front of me, then raised his fist, which was as big as a sandbag and was covered in dark magic, and punched me directly.

However, I have a shield of light formed by the blade of light, so it shouldn't hurt me...

But...

just as I expected, the shield of light couldn't withstand his powerful blow at all, and it collapsed right after that punch.

However, the hardness of the Blade of Light is basically the same as that of my Aurora Blade, so even if it is disintegrated, it will not shatter.

It will just scatter in the air in pieces and will no longer be able to reassemble.

The force of the impact sent me flying several meters through the air.

Luckily, the Wings of Light provided cushioning; otherwise, I would have definitely crashed into the wall and been in excruciating pain.

However, how did he suddenly turn from a mage into a melee mage...?

Seriously, there are so few melee mages in this world.

Although there is only one, the sudden appearance of a fake Demon King, Duke Harman, makes me a little annoyed.

Since he's also using a melee mage's ultimate move, I should respond to him, because I can't lose face as a melee mage!

At this moment, I circled the Aurora Blade in my hand three times in the air, and then with a forceful lift, I retrieved the scattered blades of light.

That's right, we have to get serious when dealing with this guy.

Although he is very strong, he was blinded by what he saw and did not consider that he was actually stronger than him, because I am already a demigod.

In fact, he is roughly equivalent to the White Snow Serpent God, but he is very likely not as good as him.

Therefore, I should overcome my timidity and fight her with my true strength.

At this moment, I took a deep breath, circulated my magic within my body, and condensed the light power on the Aurora Blade, transforming it into a sword that could cut through iron like mud.

Honestly, if I had known earlier that my actual strength wasn't what it seemed, I would have already shattered this cage.

And I still thought I was the same weak character I was before I met my mother, the goddess Shido-nai.

Sigh, how embarrassing!

At this moment, I positioned the Aurora Blade in my hand in a straight line, and then began to run slowly with small, quick steps.

That's right, I'm going to use the Royal Sword Technique, which was originally meant to defeat the Black Dragon God, to defeat Duke Harman, who has now become a demon king.

Indeed, this royal swordsmanship may seem ordinary, but it requires immense inner strength, agility, and powerful magic to control.

The reason it can completely counter the Black Dragon God is perhaps because its ultimate move requires absolute fear and the belief that one is stronger than the enemy, thus creating a unique technique.

Although the battle is against Duke Harman, who has transformed into a demon king, let's just consider it a small test before eliminating the Black Dragon God.

"Heh, what kind of ghost sword technique is this?

Even if the sword technique has changed, so what?

Look how beautiful my body is.

It's not powerful at all, hahahaha.

"At this moment, he opened his arms, and instantly, five black, misty things appeared directly above his head.

Then, the five black mists condensed into one and fired a powerful dark light cannon at me.

However, with my already highly focused concentration and the Eye of the Void God, I was able to predict the location of his attack in advance.

Naturally, the beam of light passed right by me and then missed its target, landing on the ground.

When Duke Harman saw that his Dark Light Cannon had missed, he was initially surprised.

Perhaps he thought it was just a fluke, so without saying a word, he fired another Dark Light Cannon at me.

As before, I stomped my feet and easily dodged it.

Sure enough, this guy was already very arrogant, and now that he saw his special move miss again, he was naturally very angry.

So he started shooting at me faster and with more power than before.

Unfortunately, the result was the same; the shot missed again.

"You brat, who are you?

I've never seen anyone who can predict ultimate moves.

""Heh, Duke Harman, listen up!

I am the daughter of the legendary goddess Chidune, Princess Ivy, the Holy Princess of the Human Kingdom!

"I responded with considerable confidence to Duke Harman, who had transformed into a demon.

Chapter 114 The Second Stage of Royal Swordsmanship: Lightning Annihilation StrikeI feel quite proud when I mention my mother's name.

Because no matter what, I am the child of a goddess.

Although she has made mistakes, she is not inherently evil.

Moreover, she loves me so much that she didn't hesitate to use her own divine bones to protect me.

Although she didn't raise me, I am still very moved by everything she has done for me.

So, I naturally and proudly called out my mother's name.

"It's actually the goddess's child, hehehe, so what?

Even the goddess can't stop it.

"He said that a black, unidentified object suddenly appeared in his hands, which kept condensing and mixing like a worm.

However, its main problem was that it kept moving around, which was really disgusting to me.

Then he seemed to be rapidly chanting an ancient incantation; yes, it was a rapid chant.

Surprisingly, this guy can chant very quickly...

Goodness, this guy who has absolutely no magic power is using rapid chanting; this really overturns my understanding.

"Here you go, you brat, Darkness Devour!

"In an instant, the disgusting object, which had rapidly condensed, was thrown into the sky.

Then, the unidentified objects came crashing down on me in a massive, overwhelming manner.

Good heavens, what kind of ultimate move is this?

Although I can sense that it contains very powerful magic, I have absolutely no idea how it will affect me.

Moreover, the area is so large that even if I could teleport, there's no way I could escape.

In an instant, I, who had been calm all along, began to panic again.

"Hahaha, you brat, you're doomed to eternal darkness.

"The moment the demon-transformed Duke Harman finished speaking, the black, unidentified object pounced on me.

In an instant, everything went black, and then I seemed to lose consciousness.

However, this moment was extremely fast, it seemed to be just a blink of an eye, and suddenly a golden light appeared in front of me.

Then, I regained consciousness.

"You're kidding me...

My Dark Devouring technique had no effect on you?!

"Duke Harman, who had been quite arrogant, widened his eyes in disbelief, as if he couldn't believe that his special move had no effect on me at all.

The monsters beside me, perhaps affected by the darkness, had turned into a puddle of mud, with no chance of survival.

Oh right, don't I have the Eye of the Illusory God?

The Eye of the Illusion is immune to all illusions and all magic that controls the mind.

The reason I lost consciousness the instant after being swallowed by the darkness was that the Eye of the Void God opened a way out for me in an instant and removed all the negative effects, which is why I woke up again in the blink of an eye.

Ah, it's so wonderful to have this Divine Eye!

I suddenly feel like I'm in love.

Hehe (#^.

^#).

Since the Demon King-transformed Duke Harman has already unleashed a rather significant counterattack, I'm certain he can't unleash any other significant ultimate move.

In that case, it's my turn now.

At that moment, I felt the time was ripe, so I took a small, quick step forward and thrust my foot towards Duke Harman, who had transformed into a demon king.

Upon seeing my attack, his face instantly showed an expression of extreme terror.

However, although his body had grown larger, he was still very agile, so my attack still failed to hit him.

However, this is only the first strike.

The subsequent attacks will become stronger and faster.

Whether he can withstand them depends on his own strength and fortune.

At this moment, a faint smile appeared on my face, because I felt that victory was absolutely in my grasp this time.

To be honest, Duke Harman, who has turned into a demon king, is far inferior to the Black Dragon God.

Since he has the ultimate move that can defeat the Black Dragon God, it is a piece of cake to defeat him.

Gradually, my attacks did become faster and faster, and Duke Harman, now in his demon form, found it increasingly difficult to dodge.

I pierced his solid muscles with countless gashes, and he sustained more and more wounds.

Since that's the case, I feel like I've almost finished accumulating energy.

That's right, that was the first stage of the Royal Sword Technique, just a way to build up power for the second and third stages.

Naturally, the third paragraph is definitely not enough, but the second paragraph is almost sufficient.

Just as he was about to lose his grip, I quickly stepped back a short distance.

The lightning on the Aurora Blade in my hand made a piercing sound like a thousand birds.

Then I bent down and leaned forward.

In the next second, lightning power gathered directly under my feet.

That's right, this is the method of using the split magic that the Snow Serpent God taught me.

Actually, this is equivalent to me using fusion magic...

But no, it wasn't that.

It was just that I normally cast light magic, and then I gathered lightning power in my feet to charge forward, while the sword blade was also wrapped in light magic with lightning power.

Light magic and lightning magic are inherently easy to combine, so this doesn't really qualify as mixed magic.

If you call it mixed magic, then it really is...

In short, they amplify each other's effects.

Actually, I've never actually combined the two, because I've succeeded before, but...

it consumes a lot of magic and stamina.

At most, I can only unleash four second-stage attacks and two third-stage attacks.

Therefore, this special move page became my ultimate weapon.

Now, I'm truly lucky to be able to unleash my ultimate technique and experience its power, especially since I've transformed into the Demon King Duke Harman.
