[57] The Insignificant Entity that Pierces the Wall of Fate

[Your daughter, Melusine Pendragon, has been born.]

[Watching the witch happily nursing your daughter, a complex and peculiar emotion wells up in your heart.]

[It's not about the future breast milk being stolen...]

[But rather... you now have a daughter.]

[Love, compassion, cherish.]

[As if wanting to bestow all the beauty of the world upon her.]

[And a kind of trance, an unreal feeling.]

[Being a father at sixteen, it sounds harsh, indeed very harsh.]

[But your soul has accumulated to forty, even considered a latecomer as a parent.]

[Morgan hands the daughter to you, and you gently receive her.]

[Looking at the small and lively life in the swaddling clothes, a palpitation stirs in your heart.]

[Small...]

[...Yet, full of vitality?]

[Your inspiration suddenly surges.]

[You abruptly realize a remarkable enlightenment, perhaps able to bypass the barriers of the world's will.]

[After replenishing the magical energy for the witch, who slept contentedly, you head to the underground laboratory where you were born.]

[The spiritual aura here is the most abundant and will become your experimental lab for implementing your ideas in the future.]

[You travel to the forest outside under the night sky, returning with a full load in no time.]

[You set down the things you've stored in the shadows... various mushrooms, fungi, and decaying branches and leaves.]

[You grip the Firelink Greatsword, now storing the 'souls' of thousands of humans, the result of your recent efforts to stabilize the kingdom.]

[With the support of the sword, your focus and spirit continue to concentrate... gradually concentrating into the subtle depths.]

[You glimpse the basic cellular structure of living beings, the various invisible bacteria and fungi...]

[Compared to humans, or any visible animals or plants, the volume of these single-celled organisms is minuscule, nearly negligible.]

[At the same time, their 'souls' are also incredibly light.]

[Therefore, if you use the effect of the sword to influence and transform these single-celled organisms, the consumption is almost negligible.]

[Under your intense concentration.]

[You begin to use the special effect of the your sword flame to modify the internal structure of these single-celled organisms, allowing them to grow runes that absorb true ether inside their bodies.]

[The consumption for your magical energy and soul is not significant, but the burden on your spirit is substantial.]

[In this tireless manner, you begin to try and modify various types of bacteria, fungi, and single-celled organisms, gradually, you fall into a drowsy state...]

[You feel that in the darkness, someone gently covers you with a blanket, and you grab her hand, the familiar and soft touch immediately meeting your lips, your inspirations linking with each other.]

[You open your eyes, and before you is the witch with her brilliantly glowing blue eyes.]

[After giving birth, her figure seems to have become more voluptuous, exuding a kind of maternal love, as well as a captivating and mature charm.]

[With a charming blush on her face, she leans down and presses your face against her ample chest, and her silky thin nightgown soon slides down.]

["Hubby, it's time for me to replenish magical energy❤️."]

[Amidst the applause.]

[A dreamless night.]

[Artoria vigorously promoted various political reforms in her kingdom... abolishing nobility, transforming various bureaucratic regions, and shattering titles into a bureaucratic system, striving for the benefit of the common people.]

[Based on the policies you implemented, she also made various optimizations according to the local conditions.]

[Hearing such news, you felt very gratified.]

[The teaching indeed had an effect.]

[King Arthur, wielding the Excalibur, couldn't be defeated by the entire Knight of the Round Table. Who would dare to resist her will among those lords?]

[And wherever she went, the Excalibur floated behind her, undoubtedly a tremendous deterrent.]

[Assets confiscated, territories merged, the nobles and knights who had their family lines overturned were bitter but didn't dare to blame the sacred King Arthur, they feared that Artoria would really destroy their homes.]

[So, the knights blamed all the sins on you, the mastermind behind these reforms!]

["Damn it, it must be Alvin Pendragon!"]

[They accused you of being a disaster, an unknown entity, a terrifying shadow that corrupted the king's mind and tarnished the saintly radiance!]

[You gained a new title: 'The Disaster Son of the White Dragon.']

[The citizens of Saxon laughed in silence, is this the best they can do in cursing? It doesn't feel as impactful as butcher, tyrant, or thoroughly evil.]

[Both countries' machinery roared and operated, continuously accumulating their respective strengths.]

[With spring and autumn passing, there were no wars between the north and south. Two peaceful times passed.]

[Both kingdoms were raising their national power, and the nobility seemed to have become a thing of history. The people on the island lived peacefully, their faces adorned with smiles of happiness and contentment.]

[However... at this moment, this peace is only a temporary respite, both sides are well aware that the true time for a decisive battle will come soon.]

"...Lily, our time is running out.

"We must kill his physical body before the Anchor of the Planet is drawn, or else, when the Age of Gods returns, all will be lost."

The half-incubus magus with piercing eyes floated by the side of the golden-haired girl, sighing and persuading incessantly.

Lady of the lake, Vivian, has already set out to stop Vortigern.

However, the arrogance of the demonic dragon is overwhelming, he is the embodiment of the will of Britain, and there is no one with a stronger spirit on this land.

The radiance of the shining tower has already been half-devoured by Vortigern. If he breaks free from the thirteen restraints and projects the image of Anchor of the Planet...

...The consequences are simply unimaginable.

These are facts that anyone can understand.

However, Artoria completely ignored the words of the half-incubus.

She stood on the high tower of the castle, somewhat absent-minded, looking at the people living happily in the city under the sunlight.

With her eyes, she could clearly see the smiles on people's faces... their faces had never shown such happy smiles before.

She couldn't bear to break this peaceful serenity.

"Lily!"

Merlin was almost as anxious as an ant on a hot pan.

Although he is a fun person, he is also a candidate for the Grand Caster class, and protecting the human order is his duty.

Triggering certain events, even if he is the embodiment of an incubus, will cause his death, and the planet will fall into utter despair with no one able to escape.

"...Merlin, I no longer believe any of your words. You're not worth believing."

Artoria's tone was calm.

"I'm not worth believing, what about this world? I know you want to save Alvin. But if you want to save him, live with him, you must kill Vortigern!"

The deep green lake rippled slightly.

"Don't be stubborn, Lily. I'm doing this for your own good."

Swish...

The figure of the magus was suddenly cut through by the sharp edge of the Excalibur, bisecting him at the waist, turning into a pool of dazzling petals.

"Worthless."

Artoria casually tossed aside the Excalibur, and the sword floated gloomily by her side again.

"Merlin, talking to you in your illusion is a waste of time. I just find it amusing."

"If I were in my real body, you would have killed me long ago. I can't withstand the Excalibur, and I know how much you hate me."

The Merlin's silhouette reappeared.

With a worried expression, the magus of flowers sighed softly.

"This time, I'm really not lying to you, Lily. Vivian has set out to stop Vortigern. Now there is a great opportunity..."

"If you start a war, attract Alvin to the front lines, we can create an opportunity for you... Vivian will divert Morgan, and you can change into Morgan's appearance to sneak into Londinium!"

"All you have to do is destroy Vortigern's physical body, and his spirit will wither and die. The Age of Gods will lose all hope."

"This way, you can live peacefully and happily with Alvin!"

"Moreover, no one will know it's you! Everything will happen silently, and Alvin won't be able to hate you."

"And... how could he hate you?"

"If he really hates you, he wouldn't have taught you how to govern the country step by step!"

"You should understand, right?"

The half-incubus's body appeared again.

With a tone that seemed resentful but helpless,

"He has always been expressing... his love for you."

"Although he is ultimately Vortigern's son, he wants to uphold his father's will. But when a person dies, how can he not accept you if everything becomes irreversible?"

"Whether he will soften his heart, what kind of person he is... you know better than I do."

"And, are you really seeing these people in front of your eyes?"

"..."

Artoria tightened her fists.

Facing the dazzling sunlight, her expression seemed trance-like and stagnant.

The golden-haired girl slowly raised her hand.

As if... attempting to touch the sun.

...

"This is... hubby, have you succeeded?"

"It should be the closest to success this time."

Looking at the experimental results in front of him, Alvin seemed a bit dazed.

For the past two years, he had been engrossed in research, neglecting sleep and food.

Repeated modifications, failures, screening, and optimizations.

Finally... he saw the dawn of success.

"What is this... is it a plant?"

The witch looked at the pot of dark green water in front of her, unable to figure out what it was.

"This is... microalgae."

"What...?"

"A type of algae, perhaps one of the earliest life forms on this planet, easily found in freshwater."

"Oh." The witch suddenly realized, "Is it the reason why the lakes are sometimes green?"

"Yes, it has all the advantages I want... widespread distribution, easy cultivation, growth relying on light, and extremely fast reproduction."

Alvin caressed the witch's silver hair and said with a smile.

"Most importantly... it's edible."

The witch's expression froze.

She looked at the pot of dark green water.

For someone who tasted Alvin's cooking every day, drinking this green water... she would rather go hungry.

"In times of scarcity, as long as it keeps people alive, any food is good, not to mention the high nutritional value of this thing."

Alvin sighed.

Yes, this was a perfect food to overcome the decline of the age of gods.

Thriving possibilities.

It was imbued with the color of hope.

"I modified the structure of this pot of microalgae. While they reproduce, they can also absorb true ether from the air."

"It has almost no soul, and even Gaia cannot let it wither naturally."

"As descendants of the age of gods, the Celts can eat it. Perhaps it can barely help them survive and adapt to the environment after the decline of the age of gods."

"And even on the most barren land, it can reproduce and grow freely."

All of this... for these unremarkable algae?

Surprisingly possessing such magical effects.

Morgan only half-understood Alvin's words, but that didn't hinder her from realizing how shocking this research was.

This was a product of defying fate.

"Hubby! You're the best in the world!"

The witch pounced on the silver-haired youth, and her full chest instinctively pressed against his face.

Since having a daughter, she had become more and more fond of... being affectionately touched like this.

"Thanks to you, my dear. It's you who saved Britain."

"...Eh."

Listening to her husband's words, the witch tilted her head.

Alvin hugged her, and their figures melted into the shadows, appearing in the bedroom in an instant.

Looking down from the high balcony, you could see the lively princess running around in the garden, her silver hair fluttering, delicate fingertips holding flowers but reluctant to pick them, her face showing innocence and charm.

Only two years.

She had grown into an exquisite little girl.

"...Or should I say, it's our daughter who provided me with inspiration."

"When she was born, she was really cute, so small, sucking her thumb curled up in the swaddle."

"Small, yet full of vitality."

The silver-haired youth's gaze seemed a bit absent.

"As long as you give me ten years, let me gradually transform the ecological environment of this island, even if the age of gods doesn't return, I have confidence in solving Britain's future famine and ensuring that the majority of people survive."

"Ten years..."

Hearing this number, Morgan suddenly felt a bit worried.

"Do we still have ten years, hubby? Vortigern can awaken the Anchor of the Planet in at most two or three years. At that time, we will face a choice."

"I don't know, but at least, now we have a new hope."

[The sprouting of hope, seemingly causing this island to start blooming.]

[However, at this moment, an unexpected message comes from the front lines.]

[Sensing that the time is approaching, Artoria leads her army in a fierce counterattack, the sharpness of the Excalibur in her hand almost sweeping away the Anglo-Saxon troops on the front lines.]

[Except for you and Morgan, there is no one here to stop her. Looking at the frontline reports, this defeat will only take three months to reach Londinium.]

[You instruct Morgan to guard Vortigern's physical body, put on your armor, appear on the battlefield, and in an instant, darkness envelops the entire sky. The Celtic army is disheartened, defeated, and returns under your overwhelming victory.]

[However, Artoria always avoids you on the battlefield, and you understand her complex emotions. On the front lines, the situation gradually stabilizes.]

...

In the castle of Londinium.

On the dark throne, a sudden crisp sound echoed.

Crack.

A crack suddenly appeared on the blood-red crystal that covered half of Vortigern's body, reflecting an image of a lake. Morgan, alert, quickly understood the situation and immediately guessed the origin of the trouble.

"Vivian?"

An angry expression appeared on her face, and her figure abruptly disappeared into the shadows.

"This time, I'll settle the score."

...

In the chaotic-colored space.

The towering anchor of the planet, connecting the inner and outer sides of the world, had its radiance dimmed by half.

A sturdy old man stood before this anchor, seemingly meditating with his eyes closed. He raised his hand, and the light continuously gathered in his palm, gradually forming the phantom of a long spear.

Suddenly...

A silent lake spread from somewhere, flooding his lower body.

Crackle.

Countless heavy chains extended from the surface of the lake, abruptly restraining Vortigern's hands and feet, interrupting the progress of his light devouring.

"Vivian? You can't stop me. The lake water you spent so much effort to bring here can only delay me for three to five days at most."

"Being able to stop you for one day is enough."

Vortigern's robust figure was completely immobilized on the lake surface covered with chains, unable to move at all.

However, his ash-gray eyes remained deep and steady as a quiet pond, showing no ripples.

Cracks silently spread on the chains.

...

"Artoria, this is your best chance. Infiltrate Londinium, destroy Vortigern's physical body, and no one will know it was you..."

Ignoring the half-incubus's advice.

The voluptuous golden-haired woman lowered her eyes slightly as she looked at the full-length mirror in front of her.

Relying on the restoration effect of Avalon's sheath, she had unleashed the suppressed growth that had been held back by the Excalibur, and her body instantly became plump and full.

Her face required no adjustments.

Whether it was her figure or appearance.

At this moment, she almost... looked exactly like that witch.

No need for any illusions.

Her hands gently brushed through her smooth long hair, letting it fall freely.

The brilliant golden hair instantly dyed with a slight blueish-silver color.

"Alvin..."

Adjusting her crown properly,

She silently draped over the enchanting and mysterious veil that had always belonged to the witch.

...

[You returned to the front lines' castle. In the past few days, you have stabilized the situation on the battlefield, and with intense magical consumption, you were ready to take a brief rest.]

[However, unexpectedly, when you opened the bedroom door, Morgan had already been waiting inside. You were somewhat surprised as to why she didn't guard Londinium and came here.]

[But seeing those eyes with a shimmering blue-silver color, everything became clear without words.]

["Is this how much you missed me after just a few days, my dear."]

[You smiling.]

[Then, she passionately sealed your lips and directly pressed you onto the bed...]
