Became The Son Of The Final Boss [EN]: Chapter 253

253.

“Advance!”

The moment I spotted the Undead, I gave the order to advance.

The great advantage of cavalry lies in their mobility and the sheer breakthrough power to scatter enemies instantly.

I intended to exploit that advantage to its fullest.

I positioned the highest-grade spirits on the flanks of the cavalry, and a wind spirit at the vanguard.

KWAH-!

The battle commenced immediately.

‘I don’t sense Olivia’s presence.’

Something must have occurred, because Olivia was nowhere to be seen among the Undead guarding the altar.

‘Nor is the High Priest…’

I used my skills in rapid succession, searching among the Undead for Olivia.

‘She has to be somewhere.’

I scanned the surroundings intently.

The battle raged fiercely, but thanks to the spirits, the cavalry wasn’t taking excessive damage.

Having completely shattered the Undead’s formation, we were gaining a clear advantage in the fight.

‘Is that…?’

I noticed a small hill near the altar.

It was ideally situated for scouting, and logically the first place a battle would erupt if the enemy spotted us.

I immediately spurred my horse onward.

“Your Highness!”

“Take command here. The highest-grade spirits will continue to aid in the battle. I’m going to find Olivia.”

“Yes, Your Highness!”

The adjutant’s energetic reply was brimming with confidence.

I carved a path through the Undead blocking my way, using intermediate-grade spirits.

KWAH-!

Hundreds of wind blades sliced through the bodies of the Undead.

It was clear that the Undead near the altar were different from those I’d encountered so far.

Even Ghouls weren’t easily felled by the wind blades.

Even though these were intermediate-grade spirits, the power of the wind blades naturally grew stronger as I did.

It was quite shocking that such a skill couldn’t take down a Ghoul in a single blow.

‘We’ve gained an advantage in the battle with mobility and breakthrough power, but we’ll be pushed back as time passes.’

I needed to find and rescue Olivia as quickly as possible, then return to the main battle.

I had left the highest-grade spirits behind, but a Spirit King was ultimately needed.

Fortunately, the hill wasn’t far, and I arrived quickly.

A thick aura of darkness enveloped me.

‘I’m glad I came alone.’

Even the knights would have difficulty enduring this aura.

I surmised that the High Priest was here, or perhaps an Undead creature receiving the brunt of the dark power flowing from the altar.

‘Space is distorted.’

I immediately summoned Sylphid.

Losing one of the highest-grade spirits in battle would be a significant loss, but the only way to break through this barrier right now was with a highest-grade spirit.

There was too much battle left to summon the Spirit King right away.

The blades of wind scratched at the wall of the barrier.

TSZ-!

The barrier cracked, and the inside slowly became visible.

“Olivia!”

I immediately felt Olivia’s presence through the gap.

I poured more mana into the highest-grade spirit.

The power of the wind blades intensified.

KWAH-!

The barrier shattered completely, and I immediately entered.

Suddenly, countless black spheres rained down on me.

Sylphid blocked my path and unleashed blades of wind at the black spheres.

KWAH-!

“Y-Your Highness!”

It was Olivia’s voice.

“Olivia!”

“Oh, am I a little late?”

And I heard an old man’s voice.

The old man, revealed through the black spheres, waved his staff while wearing a black robe.

“Since the source of evil has come to my land of its own accord, I must welcome it, right?”

I immediately summoned the Spirit King.

Wind Spirit King ‘Aquilus.’

That was the newly bestowed name of the Wind Spirit King.

Aquilus responded to my call and slowly materialized.

GOOOOOOO-!

Everything in the vicinity of Aquilus’s summoning began to dissipate.

The High Priest’s face hardened.

‘He probably doesn’t know. He must have heard that I can summon the Spirit King, but he must have been certain that the Spirit King could never be summoned to the middle realm with his full power.’

I also tried to maintain a calm expression.

The amount of mana being drawn into Aquilus was far greater than I anticipated.

‘I can’t even dream of summoning two Spirit Kings at the same time.’

Even the highest-grade spirits automatically returned to the spirit realm.

This was partly due to the sheer amount of mana consumed by Aquilus, but also because the other spirits couldn’t withstand Aquilus’s presence.

It seemed that Aquilus’s subordinate spirits were greatly affected because this wasn’t the spirit realm but the middle realm [the mortal realm, between the spirit world and the celestial planes].

KWAHHHH-!

When Aquilus revealed his complete form, I felt a shock that nearly stopped my breath.

‘Indeed, a form befitting the name Storm.’

It was a word I had encountered in ancient literature, and I felt I had named the Wind Spirit King well.

The High Priest’s face contorted rapidly, and he hurled hundreds of black spheres at Aquilus.

The black spheres literally vanished without a trace in the wind generated by Aquilus.

Not just the black spheres.

The dark energy that had been thickly spread around the space was completely disappearing in the wind.

-The spirit’s energy is the antithesis of the dark energy and the demon’s energy.

I nodded at Aquilus’s words.

“That one must be killed.”

Aquilus raised his hand.

Aquilus’s appearance in human form was full of dignity.

The High Priest’s appearance began to blur.

“Truly, you are the source of all evil.”

“Looking at it, it seems like I am purifying evil right now?”

The High Priest completely disappeared at my words.

But his answer was clearly heard.

“Soon, God will punish you.”

I rushed to Olivia.

“Are you okay?”

“Yes, Your Highness.”

“Aquilus, take care of the Undead.”

Aquilus’s form transformed into wind.

I supported Olivia while watching Aquilus’s form.

Aquilus, who had instantly appeared in the midst of the Undead, was drawing everything in.

* * *

With a tremendous earthquake, the altar collapsed.

The dark energy that had been spreading near the altar had completely dissipated.

“Will people be able to live here again?”

I nodded at Olivia’s words.

“The spirits are coming back.”

Immediately, the lower-grade earth spirits appeared.

They were diligently roaming the ground, purifying the land that had been tainted by the dark energy.

It wasn’t as dramatic a purification as the Spirit King’s, but it was purifying little by little.

And the earth spirits didn’t rest.

Perhaps, over time, this land would return to a place where people could live as before.

“Spirits are beings that circulate the power of nature to balance the world. Now that the altar has collapsed, this land will be restored by the power of the spirits.”

Olivia said carefully.

“I think it’s fate.”

“Fate?”

“Yes. The Purifying Flame Order, a demon-worshipping group, has appeared, and they have been influencing various countries from behind for a long time.”

“That’s right.”

“They were the ones who assassinated the Empress and tried to destroy the Empire.”

I nodded.

While pretending not to listen, the adjutants and knights perked up their ears at Olivia’s voice.

They seemed curious about the mystery of the word fate and where Olivia’s story would lead.

“They are building such altars to summon the Demon King and are actually increasing the possibility. But what they didn’t think about was Your Highness’s existence.”

Olivia’s words continued calmly.

“Your Highness has grown rapidly, and as if waiting for Your Highness’s growth, the Purifying Flame Order has risen to the surface.”

“Are you saying that I was born with the fate to stop them?”

Olivia nodded.

“Your Highness is now not just summoning spirits, but has become a being who can summon the Spirit King himself to the middle realm. You have become able to use the spirit’s energy, which is the antithesis of the demon’s energy and that dark energy, in the strongest way.”

Even I found it quite persuasive.

‘Is that really it?’

I don’t believe in fate, but it started with my mother leaving the spirit book for me.

I became stronger through the system, and Karen’s existence appeared, and according to the will of the being who sent me here, I became the Crown Prince of the Calpheon Empire.

And I became even stronger, broke through the limits of the system, and became a spiritist who summons the Spirit King.

“Yes. Maybe it can be called fate.”

What is certain is that I am the antithesis of the Purifying Flame Order.

It is common sense that divine power is the antithesis of dark energy, but the number of priests is extremely small.

And they are much better at healing than fighting.

The number of holy knights is too limited, and none of them in the Empire can use Aura with divine power.

On the other hand, I am different.

Spiritists are as few as priests, but I can even summon the Spirit King, and fighting is my specialty.

“It’s real fate.”

Olivia agreed with my words.

“Yes. Heaven sent Your Highness to the Empire.”

The knights nodded.

Perhaps the conversation I had with Olivia today would spread like wildfire as a rumor.

Recently, the people of the Empire had become less confident due to repeated defeats.

The series of defeats was a huge shock to those who had always won with my father.

Naturally, the morale of the soldiers dropped, and deserters, who had rarely existed before, also increased.

Olivia took all of those things into account and brought up the theory of fate.

Now there were four altars left.

Leaving the theory of fate aside for a moment, we had to hurry to destroy the remaining altars.

“Today, we will set up camp nearby and rest. And send a messenger to deliver the news to Grenian.”

In Grenian, Ken was the main figure, and Lilian was also there.

“Yes.”

I added one more thing to the adjutant’s answer.

“While you’re there, find out about the situation in the west and south.”

I had thought this place was the enemy’s homeland and attacked without hesitation, but the Empire’s homeland was also like a lamp before the wind [in a precarious situation].

The west had already been almost pushed back, and the south wasn’t much different.

‘We must not be pushed back to the capital.’

I trusted Duke James.

Gale was there, and most of all, my father was also recovering.

We would not be helplessly defeated.

Soon, soldiers began to set up camp in a suitable open space.

Olivia came to my side and said.

“I told them to tell Ken about the story of fate separately.”

“Are you planning to spread rumors intentionally?”

As expected, Olivia didn’t bring up the theory of fate because she deeply believed in it.

It was one of the political moves.

“Yes. We need to raise the morale of the people of the Empire. His Majesty’s defeat is a very big shock, so we need a rumor that can offset it. And Your Highness’s theory of fate is a material that will be well received.”

I chuckled.

“Amazing.”

“I guessed that Ken would have come up with the theory of fate if he had seen Aquilus. The presence of the Spirit King… was enormous.”

“A presence that even a Sword Master would shudder at!”

Olivia gave her opinion at my words.

“It felt like seeing a higher being. I wonder if it would feel like that if an angel or demon manifested directly on this earth….”

Olivia asked one thing.

“The beings they summon, the Demon Kings, can’t exert all their power in the middle realm, so they are making various preparations, right?”

“That’s right.”

“Your Highness summons the Spirit King so that he can use his full power, so wouldn’t it be possible to stop the Demon King even if he is summoned?”

I shook my head.

“I am summoning the Spirit King, but they are causing the Demon King to descend. The difference will be very big.”

“Summoning and descent….”

“The difference in power may not exist. But descent means that the Demon King will continue to stay in the middle realm. Just the altar alone turned people into Undead. What if the Demon King descends and spreads such dark energy throughout the world?”

Olivia’s expression hardened.

Just imagining it was a terrible thing.

I said firmly.

“We must stop the Demon King’s descent itself. That’s what we have to do.”

I didn’t bother to say what was on my mind to Olivia.

‘Maybe it really is the fate given to me.’

It’s not too late to think about what to do after stopping the Demon King’s descent.

To create a better Empire to live in.

That is what we must do after preventing the risk of destroying the world.

And I was determined to do it.
