The Key to Defeat Vortigern

"Hey, where did this sword come from? I've never seen you use it before."

Nidhogg's voice resounded inside his mind as she asked with a puzzled expression.

"Fallen from the sky."

Arkhan replied casually, reaching out to grasp the hilt of the Xuanyuan Sword.

The golden sword suddenly emitted a faint, ethereal glow. After a moment, the light dissipated, replaced by a crimson gold spear.

The spear looked nearly identical to Gae Bolg in terms of length and shape, except for the addition of some stylish golden patterns on the shaft and a gold-colored spearhead that gave it a touch of luxury, making it quite stunning.

"Is this like a premium skin?" Arkhan mumbled to himself, then casually swung the spear. To his surprise, it felt even better in his hand than Gae Bolg.

This was the unique characteristic of the Tenth Divine Key—it automatically transformed into the most suitable form for its host, whether it was a sword, a spear, or even a missile.

Arkhan infused magical energy into the crimson gold spear, causing the shaft to erupt in blazing flames, so intense that it distorted the air.

After a while, the flames gradually subsided, replaced by wisps of icy blue frost emanating from the spear, rapidly covering the ground beneath Arkhan with a layer of chilling frost.

This was the second ability of the Divine Key, the power to control elements like flames, frost, thunder, or wind. It could rival even some of the Divine Keys in its mastery of elemental powers.

If divided into the level of Noble Phantasms, this Tenth Divine Key would be somewhere between 'B+' to 'A+'. However, it all depended on the harmony between the host and the Divine Key. The higher the harmony, the greater the potential.

As the main host, Arkhan had the highest level of harmony with the Divine Key.

Furthermore, he noticed that despite the name 'Xuanyuan Sword', it didn't receive any mythological correction from this world. It remained just a Divine Key.

It was clear that this Xuanyuan Sword was not the same as the famous one from legends.

"Is this all it can do?" Nidhogg scoffed. "I thought a shape-shifting weapon would be more impressive... is this it?"

She had witnessed Arkhan's use of the Abyss Flower and compared to the lance with the power of life and death, this weapon seemed merely decorative.

"Don't jump to conclusions so quickly..." Arkhan said, a slight smile curving his lips. "The real miracle is yet to come."

He held the Divine Key with both hands and slowly pulled it apart. In a hazy, faint light, he ended up with two identical crimson gold spears in his hands.

Nidhogg was left dumbfounded, unable to utter a word.

Arkhan experimented once again, confirming that the power of these two Divine Keys was identical and not weakened compared to the single spear he had before.

"Exactly as I thought!" Arkhan couldn't contain his smile.

This was the third ability of the Divine Key—infinite replication!

Due to being forged from the core of the Herrscher of Legion, the Divine Key possessed the ability to infinitely replicate itself, with each copy possessing the same power.

This was the primary reason he valued this Divine Key so much.

One A-rank Noble Phantasm might not be fearsome, but what about thousands of them?

With this Divine Key, he could truly build an invincible army!

And this army would be the key to defeating Vortigern and unifying Britain!

Looking at the door in front of him, Arkhan's face revealed a hint of hesitation and conflict. After a moment, he finally raised his hand and gently knocked.

*Knock! Knock!*

Moments later, the door slowly opened inward, and a tall figure in a black dress stood behind it. Upon seeing the visitor, a faint trace of panic appeared in her pale golden eyes.

"You... Why are you here?" Her voice was soft and timid, leaving no doubt that the person standing in front of Arkhan was not Morgan, but Guinevere.

Morgan and Guinevere were different personalities of the same soul. What one experienced, the other could clearly feel. Therefore, Guinevere knew all about what had happened last night.

Recalling Morgan's words 'I want you to have a baby with me', Guinevere was feeling so embarrassed that she wished she could just disappear on the spot.

"Aren't you going to invite me in?" Arkhan smiled lightly and gently as if nothing had happened at all.

"O-Oh, I'm sorry, please come in..."

Guinevere stepped aside to make way, and Arkhan walked in.

The room was simple in its decoration, with hardly any extravagant items to be seen.

On the table were various alchemical apparatuses and magic books filled with symbols. The air was thick with magical energy, and one could faintly sense the fluctuations of magic circles.

It was evident that Morgan had transformed this room into a magic workshop. Although it appeared calm on the surface, who knew how much terrifying magecraft was hidden behind the scenes?

'But... what's the deal with that pink bed and the large teddy bear on it?'

Noticing Arkhan's peculiar gaze, Guinevere followed his gaze, her face turning bright red in an instant, from her delicate cheeks to her crystal-clear earlobes and slender neck.

She quickly stood in front of him, her expression flustered.

"Th-This, it's not what you think, I... I..."

Guinevere's eyes were spinning, her head seemed to be emitting steam, and her speech was incoherent and increasingly anxious. Finally, she bit her lip and closed her eyes.

Suddenly, her aura changed, and as her pale golden eyes slowly opened, they were filled with the elegance and haughtiness of a queen.

Arkhan watched this scene in silence, completely unprepared for Guinevere to be so shy that she hid away.

Morgan, who felt she had been betrayed by Guinevere, was trembling with anger and wanted nothing more than to drag Guinevere out and give her a good spanking.

She took a deep breath, gradually regaining her composure.

"You should understand that these things have nothing to do with me."

"Of course, I know." Arkhan nodded slightly. "But weren't you sleeping in this bed last night?"

*Buzz!*

Several magic circles suddenly lit up on the walls, and a terrifying surge of magical energy caused the air to tremble slightly, giving off a highly dangerous aura.

Morgan's face revealed a hint of a friendly smile.

"I'm sorry, I didn't quite catch what you said earlier. Could you please repeat it?"

A few drops of cold sweat rolled down Arkhan's forehead as he forced a smile.

"It's nothing, I just thought your magic workshop here is impressive. I wanted to ask if you have the time to teach me some magecraft knowledge."

"Hmph, I don't think I'm qualified to instruct someone who can master Primordial Rune."

Morgan snorted and waved her hand, gradually restoring the room to its calm state.

"I'm not kidding, really..."

Arkhan shook his head helplessly.

"I came to find you because I wanted to learn more about magecraft from you."
