Proof

The Matou family planned the command spell system, the Tohsaka family provided land (Ley Lines—spiritual vein) support, and the Einzbern family was responsible for constructing the Holy Grail system.

These three founding families of the Holy Grail War each have a slot to participate.

Out of the seven slots, three are taken up by these families while the remaining are chosen by the Grail itself.

Now, Matou Zouken still held the Matou family's quota to participate in the war, which meant that Matou Shinji was the master selected by the Holy Grail system.

After all he was one of the founders of the Holy Grail War, so he understood its meaning better than anyone else.

So this command seal meant that the system believed that Shinji met the minimum requirements to be a Master, acknowledging him as a mage capable of controlling a Servant.

A six-year-old Master, who was just an ordinary child without magic circuits a year ago...

Absurd!

Matou Zouken, who had lived for five hundred years, couldn't help but cursed in his heart.

He was the creator of the command Seal system so he could easily identify the authenticity of the command curses.

The unique magic power fluctuations and the huge magic power reaction of the Command Seal recited by Matou Shinji could not be a forgery.

This situation was not what he expected.

"hehe."

He let out a cold laugh and looked at his grandson who felt strange to him: "Shinji, do you want to commit suicide? Although I don't know why you have changed so much in one year, but you are just a six-year-old child.

It's a ridiculous joke for children to participate in the Holy Grail War."

"If your goal is the Holy Grail War, and now that I am qualified to participate, does that mean I am qualified to inherit the Matou family's secrets?"

Matou Zouken shook his head, "It's too early to draw a conclusion now. Tell me, Shinji, what do you want?"

"I promised the eldest daughter of the Matou family to protect Sakura, and this is also my responsibility as her brother."

"Ah, how touching. So, to you, a girl who became your sister less than two months ago is more important than the Matou family?"

"That's not the case. I think I am more suitable to inherit the Matou family's secret magecraft."

Matou Zouken stared at Matou Shinji for a long time, and said slowly: "Okay, if you perform well in the Holy Grail War a year later, I won't be able to consider letting you inherit the Matou family. However, the transformation of Sakura needs to be continued."

Hearing this, Matou Shinji's face darkened: "Can't you give me even one year? I will win the Holy Grail War, proving that I am the most suitable person to inherit the secrets of the Matou family.

Sakura has no need to accept transformation."

The latter sneered disdainfully and said: "Haha, you are really calm.

A little kid who has never even killed anyone wants to win the war. Don't you think it is a bit arrogant? No, it doesn't matter.

Now Sakura's age is just well, the younger she is, the more suitable she is for transformation.

So she is a very good material. There is no reason to waste the best period of teasing and teaching her just because of your arrogance."

Matou Shinji frowned when he heard this, and cursed this old immortal bug in his heart.

This bug was more stubborn than he thought.

Even the command spell couldn't convince him.

But if he continued, sooner or later the conversation would break down.

Both of them could not give in on whether Sakura should use the Marking Insect to transform her magical properties.

In the final analysis, he could not prove that he had value over Matou Sakura.

In the original work, Matou Kariya agreed on the condition of continuing to transform Sakura's body, but in the end he failed to save her..

Now Shinji did not want to see her repeat her tragic fate.

'Am I going to start a war with this old bug here?'

This was the scene that he least wanted to see.

Matou's house was Matou Zouken's lair, and every corner was filled with the insects he raised.

Even if he went all out, he didn't think he could defeat this old bug and save Sakura, in the end they both would die and he would get a zero score, and get erased permanently.

So he definitely could not fight him now.

But then again, he also couldn't give up Sakura...that was even worse than him dying so he needed to negotiate.

To continue negotiating, he must have a sense of proportion.

Firstly, he must show his unyielding determination, and secondly, he must prove that he is worthy of waiting for a year.

Matou Shinji took a deep breath, his mind changed quickly as he stood up in front of Sakura, raised his head and stared at Matou Zouken on the stairs and said firmly: "I'm sorry, I can't take a step back from my current position. "

"Hmph, Shinji, do you want to resist me?"

"It's not resistance, it's proof."

"Haha, your personality is very similar to Kariya, but he was not so bold as to rebel against my orders when he was just a little kid.

Such a promising grandson is quite endearing.

Shinji, I will give you a way to prove yourself.

Chances are, if you can escape from the basement to the surface, I will recognize your ability and postpone Matou Sakura's date of transformation until after the Fourth Holy Grail War. How about that?"

Matou Shinji agreed without hesitation: "I accept."

"This is the breeding ground for insects in the Matou family. They are not honest enough to give up hunting after their master leaves. Don't die here, Shinji."

The old buy sneered and left from the door.

Looking at his back Shinji breathed a sigh of relief.

This was the character of this lonely and disgusting old bug.

From a Magus' point of view, he was kind to his family, but in the eyes of ordinary people, he was a complete cold-blooded monster.

What he meant just now was...

If something unexpected happened to him, he would definitely stand by and watch with a smile as Matou Shinji was tortured to death by insects.

After the owner left, the bugs in the nest became restless, with a few bugs escaping into the shadows and more pouring out from all directions.

There was the buzzing sound of a large number of bees flapping their wings, the tearing sound of carapace collision, and the weird sound of squirming insects.

In the blink of an eye, Shinji and Sakura, who were staying in the basement, were surrounded by a large number of different types of insects.

Mosquitoes around the size of fists swarmed over the basement, their thin needles glowing with metallic light.

Hundreds of arm-thick black and red centipedes emerged from the cracks in the bricks.

There were also disgusting-looking mosquitoes that hissed at Matou Sakura.

"Brother...Brother!" the little girl nervously pulled on his sleeves, her face shrouded in a cloud of uneasiness and fear.

Matou Shinji looked around in disgust, and suddenly had an idea in his mind: "This is a basement created for cultivating bugs. It is quite humid, so it is just right."

He clapped his hands, and activated the refining formation constructed using simulated circuits under his skin as a faint blue light burst out from his palms.

Matou Zouken didn't take action, and it wouldn't be a big concern if his opponents were just these insects.

A qualified alchemist's combat ability is much stronger than that of regular magis in this world.

A national alchemist level can basically match that of ordinary servants.

The immortal alchemist Schuler was the best among the national alchemists.

He was good at body alchemy and was proficient in all major alchemy arts.

So he activated the Alchemy with a ritual that suited this world.

The magical energy integrated with the origin of Matou Shinji's own flow attributes, maximizing the power of alchemy and controlling the flow of heat.

This was the alchemy that Isaac McDougal, the frozen alchemist, excelled at.

Shinji opened his hands, and white bolts formed by the condensation of water vapor gathered together.

The temperature of the humid basement dropped sharply, and the moisture contained in the atmosphere and underground soil quickly froze, condensing into layers of white frost.

"Although I can't reach the level of Isaac, with the magical energy stored in my body now and being in a place with abundant water vapor, it is more than enough to freeze this basement!"

"I would like to see if the bugs cultivated using Magecraft can be immune to the effects of ultra-low temperature."
