The journey of dragon transformation starting from Demon Slayer

......

It has been some time since Zouken returned to Fuyuki City. After preparing the holy relics, he returned to Fuyuki City and continued to train the master of the Matou family, Matou Kariya.

Under Zōken's careful training, his son Matou Kariya finally showed some signs of being a magician.

His current magic skills are probably above that of a third-rate magician, and his magic circuits are definitely at the level of a first-rate magician.

There is nothing much to say about the level of magic. The most important thing for an Insect Manipulator is the precise control of his familiars and the tactical planning in his mind.

Even if there won't be a head-on confrontation, it's okay to just be the sixth in command in secret, right?

Zouken did not have high expectations for Kariya in terms of magic. Apart from magic battles, what he tested most was his grasp of the surrounding environment, as well as his own hiding and escape skills.

As for the magic circuits that were at the level of a first-rate magician, it was all thanks to the contribution of Kariya's elder brother, Matou Tsuruno.

Thanks to the blood relationship between Kariya and Tsuruno, and Tsuruno's magic circuits that had been cultivated for many years, and with the blessing of "Blood Relatives Buff", Zōken skillfully used his insect arts to deprive and devour Tsuruno's circuits, and then transferred them to Kariya's body, completing the complementation of magic circuits.

Because Tsuruno's magic circuits were intact, Zōken showed no mercy when torturing him, treating him like a disposable tool, and quickly robbed Tsuruno of his vitality.

Although Tsuruno's body is not as healthy as that of a normal man, since he is a magician, the magic power he feeds back is actually more than that of devouring an adult.

After devouring Tsuruno's flesh and blood and magic circuits, Zōken's seal worm grew very quickly, and within two months it had grown into a special familiar that could be used as a pseudo-circuit.

Later, Zōken implanted all of these crest worms into Kariya's body. But since the human body is so small, he naturally had to make room for the crest worms.

Under Zōken's control, these cresting worms not only devoured Kariya's brother Matou Tsuruno, but also ate a portion of Kariya's flesh and blood. As a result, the cresting worms and Kariya adapted to each other very quickly, and they calmed down in just a few days.

It must be said that Zōken's behavior is truly unprecedented. It is estimated that only he who uses the "insect manipulation magic" can accomplish such a feat.

After a period of adaptation that was nothing short of torture, Kariya's body was almost replaced by insects, and the number of magic circuits in his body had also reached a considerable level.

If viewed from Zōken’s perspective, Kariya’s current growth has exceeded the result of 1+1 being greater than 2, and a bright red “stigma” has appeared on the back of his hand.

"Haha, as expected, the appearance of the Command Seal was within my expectations."

"Being chosen by the Holy Grail means that you have been recognized as a magician of sufficient level!"

“Let me praise you for now, Kariya…hahaha.”

The old voice echoed in the dark room, sounding a little weird and eerie.

Hearing this voice, Kariya, who was lying in the middle of the room, opened his eyes.

He lifted himself up from the ground with his arms and slowly pulled himself up into a sitting position.

At this time, Kariya had purple hair and was wearing gray casual clothes that were convenient for him to move around in. There were thick dark circles around his eyes, as if he would die suddenly in the next second.

The reason why he moved his body so slowly was not because he was deliberately delaying time, but because he was now in a special period - the adaptation period.

Just like a patient who has just undergone surgery, Kariya needs to gradually regain control of his body, but the problems he faces are more complicated than those of ordinary patients.

Not only does he need to take over control of his body, he must also establish a connection with the imprinting worms within it.

This process is not easy, because if he cannot control the dormant imprinted worms in his body, once these worms wake up for some reason, he will soon die in the mouths of the worms and become food for the worms to fill their stomachs.

Seeing Yanye's complicated expression, Zang Yan asked happily.

"How are you adjusting, Kariya?"

"After all, it's a rare day off. Let alone showing a smile to me, at least you should make your expression a little more relaxed..."

Zōken, leaning on his cane, moved slowly towards Kariya's side under the dim light.

Seeing Zōken approaching, Kariya narrowed his eyes and revealed an unhappy expression.

"I don't need you to worry about me yet, vampire!"

"I think no one knows the situation of insects better than you, right?"

Kariya's answer caused Zōken to let out a sinister laugh.

"Haha, it seems that gentle means are still very useful! Seeing that you can still keep your sanity means that my efforts are not in vain!"

"Speaking of this, I have to thank your elder brother. If it weren't for Tsuruno..."

“Enough!” Kariya suddenly shouted, stopping Zang Yan from saying the next thing.

Then, Kariya looked at the cold ground and murmured, "Since he's already dead, why bother mentioning him..."

Kariya had known about Tsuruno's experience for a long time. It would be more accurate to say that Zōken couldn't wait to tell him about it after returning home. It was as if he wanted to show off to him.

Kariya had long known that this strange old man had a bad character, but he didn't expect it to be this bad.

This was the first time that Kariya saw Zōken killing one of his own people. In the past, Kariya would not care about what this old magician did, but the fact that he attacked his own people made him extremely fearful.

In the past, Kariya had thought that the worst outcome would be having his body taken over, but he had not expected that even if he was far away from Matou, this vampire would still have a way of controlling the fate of others.

Although Kariya had no feelings for his elder brother whom he had not seen for a long time, he still found it difficult to accept his elder brother's death.

Since the eldest brother came first, will he be the next?

After learning this news, Kariya would often ponder silently while transforming his body.

"Why is that...?"

"Why is human life so fragile?!"

Seeing that his example of killing a chicken to scare the monkey had a very good effect, Zang Yan couldn't help but curl up the corners of his mouth.

“Haha, do you hate your brother so much? Kariya…”

Zang Yan paused for a few seconds, then spoke thoughtfully.

"Yes, maybe to you, your close tribesmen are not as good as the women outside..."

At this moment, a trace of anger flashed in Kariya's eyes, and he suddenly interrupted, "Let's get to the point! Vampires!"

"You must have something to do here, right?!"

Kariya showed an impatient expression on his face, and urged the old man in front of him, "Whether you want to transform your body or learn magic, just come on!"

Zang Yan narrowed his eyes and grinned.

"Hehe, young people are indeed impatient..."

After a pause of a few seconds, Zang Yan's expression suddenly changed.

He looked serious and spoke in a straightforward tone.

"You guessed right. I came here to tell you something!"

"The Holy Grail War has now entered its final countdown stage. If all seven Servants have been summoned, the signal for war may be lit the next day."

"However, if the Seven Heroic Spirits are not gathered, the date of the Holy Grail War will be delayed for a while..."

Looking at Kariya who had fallen into silence, Zōken spoke confidently.

"It will probably take a day or two. I need you to adapt to your new body as quickly as possible during these few days!"

"Although I'm being forced to do this, I believe this amount of time is enough for you..."

As he spoke, Zōken poked Kariya’s body with his cane, causing Kariya to groan a few times.

"As a reward for your hard work, I have prepared a suitable relic for you. Please do not let your 'father' down, Kariya..."

Although he said the word "care", Zōken's voice was full of coldness.

In this gloomy basement, the cold air made Kariya's body tremble uncontrollably.

Kariya knew that if his performance did not meet Zang Yan's standards, then this old guy would definitely take this opportunity to make a big fuss.

I guess the torture would be light at that time. If it is more serious, it might even deprive him of his life and hard-earned strength.

He knew that if he could achieve his long-cherished wish, Zang Yan would not cherish anything, even the lives of his family members would be no different from dust in his eyes.

I have been learning magic for about a year now.

From disgust at the beginning to gradual acceptance, Kariya felt that he had changed a lot, but he didn't know whether this change was good or bad.

Perhaps the only thing that will not change is the hatred towards the magicians - Matou Zouken and Tōsaka Tokiomi.

But then again, now he has not only delved deeply into the way of magic and experienced the power of magic, but he also feels the wonderful feeling of holding the power in his hands.

If he were the current him, it would be a piece of cake for him to defeat his former self.

The insects that were once frightening to him were now controlled at will by him, and the extraordinary power he felt over ordinary people made him feel reluctant to leave.

Although he still has a certain degree of fear of magic, Kariya is no longer the same person he used to be.

Perhaps it was because of the surrounding environment and Zōken's 'gentle treatment' that Kariya became more and more courageous.

If it was Kariya from the past, he would definitely feel very strange after seeing his current self!

"Summoning a Heroic Spirit?... Humph, I can do it without you telling me!!"

A confident smile appeared on Kariya's face. He looked just like a young Tōsaka Tokiomi.

"Rather, I have been waiting for this moment for a long time..."

Kariya lowered his voice and responded in a hoarse voice.

Now Kariya can't wait to test his own strength.

Although his control level is not as good as that of the experienced Matou Zouken, he can still fight him back and forth in the magic competition.

Now that he has obtained his eldest brother's magic circuit, the quality of his own circuit has also improved.

If he is given time and practices for a longer period of time, it is not impossible for him to surpass Matou Zouken.

He is still young and has unlimited potential.

If he had the chance, he would definitely twist off Zangyan's head with his own hands!

and...

Now that he has become so powerful, can he kill Tōsaka Tokiomi head-on and keep Aoi by his side openly?

The thought of being able to suppress Tokiomi in the area where he excelled filled Kariya's heart with joy.

He has always been inferior to Tokiomi since their school days, and now he finally has the chance to take revenge on him. How can Kariya endure this?

Yes, he wanted to take away everything from Tōsaka Tokiomi, just like what he did to himself...

And not only Aoi, he also wants to take back Sakura and Rin! Let Tokiomi experience the feeling of loss!

Thinking of this, the corners of Yanye's mouth curled up slightly, and he squinted his eyes and revealed a proud smile.

The dark emotion of revenge took root in Kariya's heart, quietly burning like a spark that ignites a prairie fire.

--------

A wealthy family and a very high status.

It can be said that the prodigy of El Melloi never worries about material things like money. His extraordinary talent allows him to easily achieve achievements that other magicians cannot achieve.

As for this Holy Grail War, Kenneth is determined to win.

Although he had no idea about the so-called Holy Grail, he was still very interested in the title of the winner of this ceremony. After all, this was a magic competition related to the "Holy Grail", and this would become another glorious achievement in the name of Lord El-Melloi.

Of course, Kenneth is also very interested in the Holy Grail's 'Heroic Spirit Summoning System'.

After all, Heroic Spirits are the strongest of all familiars. They are replicas of Heroic Spirits who have left their names in human history. It can also be said that Heroic Spirits are mysterious incarnations.

Now, as a lecturer in the Department of Spiritual Summoning, he can actually experience the feeling of summoning heroic spirits firsthand.

As a scholar proficient in séance and summoning, he would naturally be interested in this project.

After acquiring suitable relics, Kenneth prepared the best spiritual land for summoning heroic spirits, while using El-Melloi's financial resources to ask Solau to help prepare suitable materials imbued with magic.

With sufficient materials, Kenneth began to make a large number of magic costumes.

With such exaggerated preparations, it would be more accurate to say that he was truly preparing to go to the battlefield rather than participating in a magic competition.

......

In the private office of Lord El-Melloi, Kayneth looked at the red-haired beauty who appeared before him, and a hint of tenderness that ordinary people could not detect flashed in his eyes.

She is still as beautiful today, like a burning flame, using her arrogant aura to keep people away.

Solaw had no idea what Kenneth was thinking, but the expression on her face was as cold as ever.

"You called me here at this time. Did you find something?"

Solaw crossed his arms across his chest, his words full of disdain for Kenneth.

As Kenneth's fiancée, she has done a lot for Kenneth recently.

She traveled all over the Spiritualism Department, Summoning Department, and Mineral Department, met with the deans of each subject, and collected (acquired) the important materials that Kenneth needed.

In magic rituals, the quality of the material has a great impact on the magic itself.

Especially when making magic costumes, the concentration and "mystery" of the magic power emanating from the materials are of paramount importance.
