Caster, the Witch-Medea!!!

Yu Xian looked at the three choices and fell into thought.

Sun Breathing was powerful, but the Phoenix Fruit and Medea were both more tempting.

"Either I can fly through the sky and burrow through the earth without fearing water, or I get an obedient, living witch servant?"

"No, wait. Is Medea obedient?"

Yu Xian muttered to himself, his five fingers curling unconsciously.

[Host, Medea carries a risk of backlash. Please choose carefully.]

"Medea from Fate was a ruthless character. She would stop at nothing to obtain the one she loved."

He thought of Medea's formidable magecraft system and her strength within the Fate setting—

—high-level magecraft, a magical workshop, instant casting, control over meteor streams, and even Noble Phantasms capable of breaking magic.

Wasn't she an unconventional Scarlet Witch?

It went without saying how useful that would be in the Marvel world!

"A witch can bring more surprises than a Fruit."

"Besides, I have the Idle System."

"What she needs is someone who won't betray her, someone loyal to her and capable of giving her a sense of self-worth."

"Looking at it that way, I still have a chance."

Besides, he already had Hyorinmaru and Ryūjin Jakka in hand,

with Star Platinum protecting him and Wolverine's regeneration,

such a powerful combination was enough to handle unexpected situations.

Even if he got stabbed in the back, he would not die on the spot.

As long as he did not die, he would have a chance to turn things around.

And besides, the process of interacting with Medea should be quite enjoyable, right?

"System, I choose Servant Contract: Caster, Medea."

[Warning: Once the contract begins, it cannot be revoked. Medea will be bound to the host through a magical contract.]

[The contract requires a great deal of magical power. Please confirm.]

"Confirmed. Begin the contract."

In the depths of the sea, a golden magic circle slowly unfolded before Yu Xian.

Its intricate patterns radiated a mysterious glow.

Ancient Greek letters flowed around the edge of the circle, giving off solemn magical ripples.

At the center of the magic circle,

purple light surged forth, and a cloud of mist slowly condensed into a human figure.

First came a pair of slender legs, then a slim waist, followed by graceful arms and shoulders,

and finally, a beautiful face touched with a trace of coldness.

She was a tall woman.

Her long purple hair draped over her shoulders, and she wore a Greek-style robe. Her eyes shone like amethysts,

while a golden necklace set with a ruby hung around her neck.

Caster, Medea, as a Servant, let her gaze travel over the man before her, the corners of her lips curving slightly.

"Are you the one who summoned me?"

"How interesting. I can sense more than one kind of power flowing through you."

"Caster-class, true name Medea. I have answered your summons."

"Tell me, Master, why did you summon me?"

Her voice was like a clear spring, elegant and noble.

Yu Xian narrowed his eyes. He could feel the mental energy within him being constantly drawn away, as though an invisible thread connected the two of them.

It seemed that because the world's rules were different, mental power had replaced magical power as the supply.

But judging by the current rate of consumption, he could easily sustain her daily needs.

Yu Xian chuckled, seemingly thinking of something as he teased her.

"Why?"

"My reason, of course, is to slack off better."

Medea frowned, a hint of confusion flashing through her eyes.

"Slack... off?"

"What kind of ideal is that?"

"Simply put, you'll help lessen my workload so I can live more freely and comfortably."

"So that's it. You want to use my power to fight for you."

"Very well. As long as you can provide sufficient magical power, I will fulfill my duties under the contract."

"Let me introduce myself. My name is Yu Xian!"

"Starting today, I'm your master!"

Yu Xian could vaguely sense that this witch was not as gentle and docile as she appeared.

Who knew what she was thinking about?

Yu Xian ignored Medea's gaze and took out the Second Origin, an item from the Fairy Tail series.

Looking at the glowing sphere in his hand, about the size of a longan, he swallowed it without hesitation.

The sphere burned as it slid down his throat, and in an instant, it felt as though lava was coursing through his veins.

The energy fluctuations around him surged sharply. His clothes billowed slightly as the seawater began forming a ring-shaped vortex around him.

The mental power within Yu Xian began increasing dramatically.

His original mental space was forcibly expanded to twice its former size.

His body began to glow, as though a hidden galaxy were flowing beneath his skin.

Medea watched coldly from the side.

What was this guy doing?

That energy fluctuation... it was actually this powerful. Just who was he?

As a mage from the Age of Gods, she was exceptionally sensitive to magical power. The changes in this "Master" before her left her in disbelief.

"That's impossible..."

"In just a few seconds, his magical reserves have doubled..."

Even in the Age of Gods, when the gods walked upon the earth,

such a massive increase in magical reserves within so short a time was unheard of.

"This master really is mysterious!"

"And..."

Medea examined the abilities she could wield within herself and discovered that some of her more powerful abilities could not be used, as though they had been sealed away.

Medea licked her red lips, her beautiful eyes fixed tightly on the cultivating Yu Xian. Perhaps he could answer her doubts.

Boom!

A sound erupted from within Yu Xian, and the disorderly power swirling around him was completely drawn back in. The seabed returned to calm.

Yu Xian slowly opened his eyes, and his calm gaze finally fell upon Medea's alluring figure—her lively, magnificent chest, her full, rounded backside, her long legs!

Ahem, no, no. How could he be such a beast?

Forcing down the temptation, he grabbed the floating Hyorinmaru and lightly swung his arm toward the seafloor.

Crack! Crack! Crack!

A hundred-meter-long fissure of ice instantly formed. Well, it was a hundred meters long, but wasn't this thing a little too thin? Other people made hundred-meter chasms wide enough for someone to enter. Why was his the kind that could not even fit his precious thing? Was being well-endowed a crime too?

Yu Xian grumbled inwardly as he silently watched the ice created by Hyorinmaru slowly sink to the seafloor and disappear.

"Damn, this is bad!"

Yu Xian suddenly remembered how he had gone berserk at the press conference. He had no idea whether anyone had captured it on camera.

Hopefully Catalina would help clean up after him.

He did not want to become famous. Otherwise, people would recognize him whenever he went out or picked up girls.

Hiss~ Hiss~

Hmm???

What was that sound???

Yu Xian lifted his confused eyes and looked toward its source.

He saw that the wall of flame created by Ryūjin Jakka had vanished as the energy erupting from his body ran out.

Yu Xian's lips twitched slightly as he remembered that he was still three hundred meters below the surface.

The joy from his greatly increased strength instantly faded by more than half.

The little that remained only improved slightly when he saw that Medea beside him wore an equally unpleasant expression.

Medea suddenly said to Yu Xian,

"Master, since there is nothing else, send me back."

"I have only just descended here and still need time to familiarize myself with this world's rules."

Yu Xian looked at Medea with a chuckle.

As a Servant, she should share both hardship and fortune with her Master.

How could she only think about enjoying herself?

Bang~

The only source of light on the seafloor was completely extinguished.

In the darkness, Medea's cold, disdainful voice faintly rang out.

"It seems that you still need much more practice controlling your magical power, Master."
