Heroic Spirit: I, Shinji, have tried my best.

When Medea woke up again, he saw an unfamiliar ceiling and a purple-haired boy sitting next to him flipping through a magic book.

"You finally woke up, otherwise I would have left you behind."

Medea ignored what the boy said, but looked quietly at the three Command Spells on the back of his hand. She could feel an ambiguous connection with them.

"You actually took advantage of the fact that someone couldn't resist and forced them to sign the contract. You are such a scumbag, brother!"

Obviously, Mother C still remembers what happened at that time and has a lot of complaints. After all, this textbook example of taking advantage of someone's misfortune is rare.

Shinji was also amused when he heard the term "scumbag".

"You are the first woman to call me like this, and I saved your life. You are taunting the witch by speaking ill of her like this! "

Obviously her pain point was touched, and Medea's face instantly turned gloomy.

''Who gave you permission to call me that? ''

"Are you angry already? You are as easy to understand as a child."

''What do you mean?''

"What I mean is, I have no intention of forcing you. I saved you only as a bargaining chip for our cooperation."

After saying that, the magic book in his hand suddenly ignited with purple magic flames. When the book was completely burned, Medea could feel that the vague connection was gone...

"This kind of contract signed with props is still too limited. You can't get much of my magic power, so..."

Shinji raised the hand with the Command Seal and clenched his fist towards Medea.

“Now we will formally sign the contract:

1. Party A needs to provide magic power to Party B, and Party B should provide combat support to Party A;

2. Party A cannot force Party B to do anything that violates its principles or goes beyond its bottom line. Apart from this, Party B must act according to Party A’s orders;

3. If no order is received, Party B can act independently. If Party B is dissatisfied with Party A's behavior, Party B can decide to leave or stay independently.

4. During the Holy Grail War, neither party may disclose the other party's information, nor may they launch malicious attacks against the other party.

If both parties agree to the above conditions, the contract will be concluded with the Holy Grail as an oath. "

"…Is this just a promise between children? What's the point of empty words?"

Apart from the established rules of the Holy Grail War, almost all the rest are beneficial to her as a Servant. But why should she believe in something that has no enforcement power?

"No, this is my promise as a man."

"…I remember you knew about me."

"That's why I'm saying this."

The air suddenly became quiet. Medea lowered her head, her black cloak covering her head, making it impossible to see the expression on her face.

"I hope you won't regret it... Caster Medea, please answer the call!"

The strange connection appeared again, but suddenly Medea's eyes widened and she looked at Shinji in disbelief.

"What kind of weird magical power is this!"

Shinji just smiled and said nothing.

……

At 2 a.m., in Ryudo Temple

"Why did you choose this place?" Shinji walked behind Medea and asked knowingly.

"The magical aura here is very strong. I can use the power of the earth veins to build a magic workshop here. I should also be able to exploit the loophole of the Holy Grail and summon a servant!"

"Wow, that's amazing! I really don't know how your previous master thought of abandoning you." Shinji praised him generously, but his attitude was a little perfunctory.

Medea didn't want to pay attention to the hidden meaning in the second half of the sentence. Although objectively speaking, she was very satisfied with her Master, but for some reason she just wanted to beat him up...

Shinji took a look at the surroundings, jumped to the top of the temple in a few steps, and looked at the Matou residence on the edge of Fuyuki City.

"Ten years have passed in the blink of an eye! It's time to finally get to know each other, Zang Yan!"

A flash of light behind me

"...Assassin Sasaki Kojiro, come on!"

"Oh! You're quick, Caster!"

"Didn't you say that I was in a hurry? I didn't even prepare the ritual properly, and I only managed to summon this thing. Fortunately, you have enough magic power, otherwise it would be even worse."

Kojiro: ...Are you polite?

"Oh, now that all the actors are here, let's go and say goodbye to my dear grandpa without further delay!"

……

"Hello? Nissan, you finally called! Where have you been these days? Why didn't you even answer the phone..."

"There's no time for this, Sakura. Pack up your important things. We're moving."

"Hey! You said..."

After hanging up the phone and putting it in his pocket, Shinji stood outside the Matou family's door, next to him stood a long-haired beauty wearing a purple nightgown and an eye mask.

"I remember that I should have deliberately concealed my presence, but how come you still detected it?"

The long-haired beauty replied calmly: "My perception magic did not detect you, but my hearing is very sensitive..."

"Is that so... I didn't expect much effect, so change your clothes and prepare for battle, Assassin."

Shinji pushed open the door of his house and entered the place where he had lived for seventeen years. Ignoring Sakura who was rummaging through the drawers in the bedroom, he walked through the inner courtyard and entered the dark basement again.

Walking down the dim stairs, I saw the familiar dim light, the familiar study... and the familiar old man.

"You're here! It looks like you've been through a lot in the past few years, Shinji!"

"Yes, thanks to you, Grandpa."

Shinji took several deep breaths before coming, hoping to ease his violently beating heart and slightly trembling body. After all, his wish that he had kept for more than ten years was about to come true, so he was naturally very excited.

But when the target really appeared in front of him, he became extremely calm...

"I've heard that...when a person is about to die, all the sins he has committed in his life will appear before his eyes. I just don't know if it's true."

Shinji cast a cold gaze at Matou Zouken, but the other person's face did not show much surprise, instead he smiled happily...

"Although I did find that you were somewhat special before, if you had behaved like a good kid, you would not only have survived safely, but you might even have inherited my legacy. But you chose to challenge me here without knowing whether to live or die."

"If your purpose is to convince me to stop, then there is no need to waste your words. Some things are destined from the beginning."

"Hey, it seems that you are very dissatisfied with me. I remember that I was pretty good to you! Is it because of your sense of justice? Are you coveting those magic? Or is it because... Sakura..."

Before he finished speaking, Shinji suddenly jumped up, drew out the Kusanagi sword behind him, and lightning flashed on the snow-white blade. Shinji turned into a flash of lightning and disappeared on the spot. The next second he appeared in front of Matou Zouken.

"Chidori Blade!"

Just like the sound of thousands of birds chirping echoing in this basement, the blade with arcs of lightning instantly cut the old man in half, who seemed to have not yet reacted!

In such a short time, ordinary magicians would not have time to chant, nor would they be able to resist this slash. Unfortunately, Matou Zouken is not an ordinary magician.

The body that was cut into two pieces gradually became dry, and countless flying insects crawled out of the body, flying around the room in a black mass. As a monster that has lived for hundreds of years, he had long since left the fragile human body and achieved false immortality.

But this can only save his life, but cannot restore him to his former strength, so he needs the help of the Holy Grail to achieve true immortality!
