In fact, after the contract was concluded, Medea was able to clearly sense the enormous life force within Otosaka Souji's body.

After Medea learned that Otosaka Souji was not an ordinary person, she no longer felt the guilt she had felt before for dragging down ordinary people.

Because the stronger the vitality, the more it reflects the strength of an individual, and the vitality and magic power within Otosaka Souji's body are already comparable to the fantasy species of the Age of Gods.

After Medea formed a contract with Otosaka Souji, the immense magical power and life force within Otosaka Souji allowed Medea's wounds to heal rapidly.

………………

As dawn broke, Medea, having recovered from a night's rest, got up to prepare for setting up the magic workshop.

For a caster, having a magic workshop and not having a magic workshop are two different things.

In the Magic Workshop, the caster's combat power will be greatly enhanced.

Even against the strongest Sader class, they might not necessarily be at a disadvantage.

As a magician from the Age of Gods, Medea's magic workshop was certainly not to be underestimated.

Medea plans to set up a magic workshop directly throughout the entire Ryudong Temple.

First, a barrier was created to surround the entire Ryudong Temple, leaving only one entrance and exit, which is the temple's main gate.

Then, the cannon fodder Dragon Fang soldiers are also indispensable.

Various traps, attack spells, and defense spells were all set up.

Medea laid a trap for the entire Ryudong Temple.

The magical power that sustains the barrier, various traps, and magic comes from the Great Holy Grail inside the Great Hollow Cave of Ryudouji Temple.

Medea used magic to extract a portion of the Greater Grail's magic power to maintain the barrier and traps.

Furthermore, Medea also deciphered a portion of the Holy Grail through magic.

After analyzing the Greater Grail, Medea finally discovered the truth.

That means the Holy Grail has been corrupted, contaminated by the black mud, which is the evil of this world.

Using it to make wishes will only cause greater damage, and the way wishes are fulfilled will also be distorted by it.

Here's a simple example.

For example, someone might make a wish upon the Great Grail, which is tainted by the evils of this world, and grant a fortune that they could never use up in a lifetime.

The Greater Grail, corrupted by the evils of this world, might achieve this wish by killing everyone.

Because if you are the only person left in the world, then all the wealth in the world will be yours.

In this way, you will have wealth that you can never use up in your lifetime.

The Greater Grail, tainted by the evil of this world, will ultimately fulfill its wish in the most wicked, twisted, and painful way.

Knowing this, Medea no longer had any attachment to the Greater Grail.

Medea was eager to tell Otosaka Souji about her discovery as soon as possible.

But right now, Otosaka Souji is still fast asleep, snoring away.

Otosaka Souji, who loves to sleep in, hates being woken up from his sweet dreams.

Although Medea was unaware of this, it did not stop her from caring about Otosaka Souji.

Therefore, Medea couldn't bear to disturb Otosaka Souji, who was truly fast asleep.

Otosaka Souji seemed to be dreaming about Caster while he was sleeping.

Otosaka Souji had a lewd, perverted grin on his face, and drool was practically dripping from the corners of his mouth.

He unconsciously muttered something under his breath.

"Hehehe~ *^O^*, Mommy C is mine now~~."

Medea didn't understand what C-mother meant, but she couldn't help but laugh when she saw Otosaka Souji's expression.

However, Medea did not laugh loudly; instead, she covered her mouth with her hand and chuckled softly.

Medea is very satisfied with her current life. Her gaze towards Otosaka Souji is deep and gentle, and her smile contains endless warmth, which is very touching.

"If only things could stay like this forever!"

Medea was lost in thought, considering many things, but the strongest thought among them was...

"I want to maintain my current life and stay by Otosaka Souji's side forever."

Soon, the midday sun shone in through the window.

The winter sun is warm, not hot at all.

Otosaka Souji woke up quickly after feeling the warm sensation on her face.

Medea, who had been sitting cross-legged to the side watching Otosaka Souji, had also been waiting for a long time.

Medea waited for Otosaka Souji to calm down and sit up before speaking in her mature, older sister-like voice.

"Master, I have set up a magic workshop throughout the entire Ryudong Temple and protected the entire temple with a barrier, leaving only one entrance and exit, which is the mountain gate of Ryudong Temple."

"Furthermore, I also discovered the Greater Grail in the large hollow beneath Ryudong Temple. Through my analysis, I discovered... the Greater Grail..."

Otosaka Souji yawned and looked at Medea, who seemed hesitant to speak.

"Don't hesitate any longer, just say it all."

"Yes, Master."

After Otosaka Souji said that, Medea told him all her discoveries.

"Through analysis, I discovered that the Greater Grail has been corrupted and no longer has the ability to grant wishes. Moreover, I found a strong malevolent intent within it."

"Yes, I understand, Medea. Actually, I don't have any wishes to make."

Otosaka Souji already knew what Medea was talking about.

Otosaka Souji only wanted to use Medea's magical skills to analyze the Greater Grail and Grail Ritual created by the three starter families, so as to learn how to control the Third Law and materialize the soul.

Otosaka Souji smiled and continued speaking to Medea.

"Medea, please continue analyzing the Greater Grail. After all, only you have the ability to do so."

"No problem, the Greater Grail is yours to handle, my little master."

Medea was quite pleased with Otosaka Souji's praise.

Medea felt incredibly happy that her abilities were recognized by Otosaka Souji.

Medea is full of energy right now.

Furthermore, Medea was very confident in her magical abilities.

Although analyzing the Greater Grail is a massive undertaking, Medea stated that aside from taking a little time, nothing else is a problem.

In fact, after the contract was signed yesterday, Otosaka Souji told Medea about his goals and thoughts.

Medea also expressed that she was extremely happy to do so.

Otosaka Souji felt that he was a very incompetent master.

Even though he is the Master, he doesn't have to do anything; he leaves everything to the Caster.

With nothing else to do, Otosaka Souji decided to start sensing the difference between magical power and magical essence within his body.

After sensing it, Otosaka Souji discovered that there was no essential difference between magic power and magic essence; both were transformed from life force.

The only difference might be that magic essence can be passively enhanced, while magic power requires active enhancement.

As he gained a deeper understanding, Otosaka Souji discovered that magic essence is more active than magic power, while magic power is more inert than magic essence.
