Became The Son Of The Final Boss [EN]: Chapter 240

240.

Though the System is gone, I haven’t lost my ability to grow stronger.

Even without it, I can still use the spirits’ skills.

In fact, I can utilize them in more diverse ways than before.

Ifrit alone is a prime example.

Ifrit is a bird made of flames, and wherever it goes, flames engulf the area.

What’s amazing is my ‘will’.

Spirits are, in their essence, wind, fire, water, and earth.

If I don’t want Ifrit’s flames to cause harm, even if it flies through a crowd, no one will be hurt.

On the other hand, if I send Ifrit into a crowd with the intention to harm, its flames will be like hellfire to everyone.

Even without using ‘skills,’ the mere presence of the spirits can harm enemies.

Naturally, the ways to utilize them have increased.

‘I need to get stronger.’

Of course, the ways to utilize spirits have increased, and I’ve reached a point where I’m looking beyond the peak of the highest tier, but this isn’t the end.

Undine, transformed into a small fairy, spoke.

“The power of spirits is growing stronger in the Middle Realm.”

I tilted my head.

“The power of spirits?”

“Yes. The power of nature is stronger than ever.”

I didn’t quite understand.

The continent is currently experiencing the strongest surge of evil energy in history due to the undead invasion.

The continent is being stained by darkness due to the machinations of the Purifying Flame Order.

The power of nature is directly opposed to the energy of evil.

“It seems to be a reaction to the increasing evil energy.”

Undine said with a hint of regret.

“If I were a queen, I could know more details, but I can only sense the general energy.”

“Are there spirit kings right now?”

“Yes.”

I asked, seeing it as a good opportunity.

“If Undine becomes a spirit queen, what happens to the existing spirit kings?”

“The existing spirit kings return to the pure natural energy that forms the spirit realm.”

“Is the contract with me maintained?”

“The primordial contract is more sacred than anything else. Even if I become queen, the contract will not be broken.”

I nodded, pleased.

“However, you must undergo a test.”

“Test?”

“The power of a king is incomparable to that of a high-level spirit. If a king is summoned to the Middle Realm, the nature of the entire Middle Realm will be affected; it is that powerful.”

Undine’s calm voice continued.

“The Middle Realm is a world of balance. If one side’s power becomes too strong, it will collapse. The world is currently exerting a lot of effort to maintain its balance.”

“Maintain itself?”

“Yes. Those who artificially strengthen the evil energy are continuously drawing the power of the Demon Realm into the Middle Realm. On the other hand, the power of nature is gathered by the world itself. There is a difference in speed.”

I understood Undine’s words.

“The power of artificially strengthening the evil energy is faster than the world’s own efforts to maintain balance. If things continue like this, it will be very dangerous, is that how I should understand it?”

“I believe the reason the Master of the Covenant was born in the Middle Realm is precisely because of this.”

Undine concluded.

“If the king can be summoned to the Middle Realm, the natural power of the Middle Realm will become stronger than ever, and naturally, the evil energy can be repelled.”

In the end, what’s important is for me to become stronger than I am now.

I nodded.

“I can’t break through the wall right away, but I’ve at least found a path to follow.”

What I realized is that the Wind Breathing Technique is the most important.

Even before, the Wind Breathing Technique was the foundation of all my skills.

I have the highest affinity with the wind spirit, and it was the only ‘mana cultivation method’ my mother left me.

I no longer have the System, but I have better companions than the System.

That’s the spirits.

Undine, Ifrit, Noahs, and even Sylphid.

Not only the high-level spirits but also the mid-level and low-level spirits are all helpful in training.

“Your Highness!”

I responded to the voice coming from outside the door.

“Enter.”

It was Gale who opened the door to the office and came in.

“Gale.”

Gale’s expression was serious.

“What’s wrong?”

“Hamilton has returned.”

“Hamilton?”

I rose to my feet, a welcoming expression on my face.

“The entire Kingdom Alliance has become an Undead Kingdom, and countless undead are crossing the border.”

“Summon all the soldiers.”

As I spoke, I ran with Gale towards the Grenian Castle walls.

Already, other commanders had heard the news and were heading towards the Grenian Castle walls as well.

Ken approached me and said.

“Divert the cavalry.”

“The cavalry?”

“Yes. I plan to ambush thirty thousand cavalry and, when the moon is high in the sky, collapse the undead’s formation all at once.”

Ken’s words quickened.

“With Your Highness and Lilian here, there will be no problem with defense. The most important thing is how much we can reduce the damage.”

I nodded.

“Alright.”

“Gale should take command of the cavalry.”

Gale did not refuse.

Our unit has knights from various backgrounds, but Gale is from a traditional knight lineage.

One of the virtues of a traditional knight is horsemanship.

You must be good at riding horses.

Of course, you must not only be good at riding horses but also be good at fighting on horseback.

“I will depart immediately.”

I nodded at Gale’s words.

“Go.”

I headed up to the castle walls.

* * *

The soldiers’ morale was not as bad as I had feared.

Seeing the undead army approaching, shaking the ground as if an earthquake had struck, would have been enough to make them flinch, but the soldiers on the castle walls only swallowed hard, gripping their bows and spears tightly, and strengthened their resolve.

‘The arrogance of the cavalry is definitely effective [referring to the confidence and reputation of the cavalry unit].’

The undead were gradually getting closer.

I quietly began to speak.

“The forces of evil have once again invaded this land.”

The surroundings were silent.

Thump-! Thump-!

The sound of the undead advancing could be heard.

“The Kingdom Alliance has become an Undead Kingdom. Not only the residents but also the nobles and the royal family have all turned into that.”

Ifrit flew into the sky, brightly illuminating the surroundings.

The number of undead visible under Ifrit’s flames was endless.

“If we cannot defend this place, not only we but also our families will not be able to avoid that fate. Even death cannot be an escape. Their hobby is raising corpses.”

There is no place to run, and death is not the end.

The only way out of the war with the undead is victory.

“The Kingdom Alliance has not been able to win against us even before becoming an Undead Kingdom, nor after becoming an Undead Kingdom.”

I calmly concluded.

“And today is no different.”

Ifrit boldly split the undead formation.

Mana rotated, and a considerable amount was drained into Ifrit.

Gooooooo-!

Ifrit’s flames blazed like the sun.

“Kkeueok!”

Kwaaaang-! Kwang-!

Undead were melting in the places Ifrit passed.

Wizards who appeared to be liches [powerful undead spellcasters] and undead attacking from a distance attacked Ifrit, but it was useless.

“Waaaaaaa!”

“Everyone, shoot! Don’t let a single dirty undead set foot on this land!”

With my words, the archers simultaneously drew their bows.

The catapult was activated, and a huge boulder flew towards the undead.

Kwaaaang-! Kwang-!

I also summoned Sylphid.

‘Conserve mana.’

I spoke as if we would win immediately to the soldiers, but I felt that today’s battle would also last until sunrise.

The number of undead was greater than last time, and strong undead were visible everywhere.

Dhuran [likely a type of powerful undead], and Death Knights, of which there was only one last time, were noticeable throughout the undead formation.

And they were commanding their undead.

Just like human knights.

Lilian, as if stimulated by seeing Ifrit, unleashed fire magic.

Huge fire arrows flew into various parts of the undead formation.

Kwaaang-! Kwang-!

“There must be a pretty decent lich.”

Lilian came to my side and said.

“Lich?”

“I was only aiming for liches. But there are quite a few who blocked it.”

A smile spread across Lilian’s face.

“I’ll take care of the liches. It’ll be a headache if those guys use magic on our side.”

“Understood.”

Olivia and Gale approached.

“We will spread out to both sides and defend the castle wall strongholds.”

“Be careful.”

Olivia and I made eye contact.

I could read her thoughts without having to say more.

I believe Olivia also felt my heart.

Soon, the two dispersed to both sides and headed towards the castle walls where the gates were located.

Kwaaaang-! Kwang-!

In the meantime, Sylphid and Ifrit roamed freely through the undead formation.

The undead did not just stand still and were constantly attacking Ifrit and Sylphid.

I de-summoned Ifrit.

At the same time, Noahs emerged from the ground.

‘Create a huge pit in front of the moat.’

Noahs’ voice pierced my mind.

-How deep should it be?

‘Deep enough to bury those guys.’

The ground rumbled as Noahs moved.

“Shoot!”

I once again ordered the archers and poured mana into Sylphid.

Wind Blade.

It is the skill I first became aware of and unlocked as a spiritist.

It could still be said to be a powerful skill.

The System is gone, but the skills can still be used.

Skills are one way to efficiently use the abilities of spirits.

Sylphid unleashed blades of wind in all directions from the center of the undead formation.

At the same time, it sucked out my mana and created a whirlwind.

“Your Highness, send the signal.”

Ken approached and said.

He also held a bow in his hand.

The undead have not yet climbed up the castle walls.

We are blocking them well now, but they will soon reach the vicinity of the castle walls with an overwhelming number.

I am making Noahs install another obstacle in front of the moat to delay that time as much as possible.

But to mobilize the cavalry already?

“Isn’t it too early?”

“No. It’s now.”

I trusted Ken’s judgment.

He was the military advisor of this army, and his judgment has never been wrong.

I re-summoned Ifrit.

Ifrit flew towards the eastern sky.

Raining flames from the sky was the signal.

In an instant, half of the mana hole was emptied.

Kwaaaang-!

The undead melting in the rain of fire screamed.

In an instant, over a thousand undead disappeared without leaving even a corpse.

And,

The ground shook.

The cavalry, who had been lying in ambush, received Ifrit’s signal and charged towards the undead formation.

Ken said to Lilian.

“Magician Lilian.”

Lilian nodded and began casting.

What kind of magic would a magician who has reached the 9th Circle unleash while casting?

Soon, the identity of the magic was revealed.

A pure white sphere, seemingly larger than the moon, fell among the undead.

Kwaaaang-!

The cavalry tore through the undead formation.

“Your Highness!”

I nodded.

“All-out attack!”
