Crossover Anime: I Became Invincible Starting as an Ajin

However, it is unclear whether it is due to the severe deterioration of the bloodline or some other reason.

In any case, Shinji Matou has never had any children.

Shinji believed that Matou Ryogen was only mate with Sakura because he wanted her to get pregnant with the next generation of the Matou family bloodline.

(P.S.: The ethics of magician families are different from those of ordinary people. In their eyes, passing on the magic imprint is the most important thing, and everything else is secondary.)

However, years of overexertion have rendered his combat strength incomparable to that of his peers, so he has no choice but to beat Sakura so that his soft-spoken Shinji can mate with her.

However, the fact that his sister never conceived despite working tirelessly for the Matou family every night for so many years suggests that his reproductive ability has been lost, or it is possible that Sakura's body was damaged by the Crest Worms.

There is also a theory that Shinji had no idea that his grandfather didn't need him to have any offspring, because Sakura's modification was only for the Holy Grail.

It's possible that Matou Ryogen might have his grandson Shinji act as food to replenish the magical energy of Insect and Sakura, contributing a small part to his grandfather's ambitions.

(P.S.: In the Type-Moon universe, there is a concept of replenishing mana, which is that the exchange of bodily fluids can replenish mana, such as sweat, tears, blood, etc., especially the secretions from mating.)

Shinji Matou did not inherit the aptitude of a magician, nor was he able to have children.

In the magician family, they are practically worthless, less than maggots.

Shinji, even though he cared about the glory and revival of the Matou family, was a complete tragedy from birth to death, being deceived, abandoned, and never even given any hope of growth.

Under prolonged pressure, he went from being a good brother who initially protected Sakura to becoming a crazy and cruel person later on.

It's worth noting that Shinji was initially an excellent student and had a great reputation in normal society; otherwise, he wouldn't have become friends with someone like Emiya Shirou.

The stark contrast between the before and after shows that the death of Jian Tongzhan is not a pity.

"Little friend, where's that old hag in your house?"

Wang Bai asked Matou Shinji directly.

Shinji Matou was still a child, and instinctively retorted, "Where did you come from? Why are you insulting my grandfather?"

Wang Bai had no interest in arguing with a child, so he slapped him on the bottom.

Matou Shin and his companion were both dumbfounded. After all, as one of the three founding families of Fuyuki City, no one had ever dared to hit him so directly, let alone so severely.

By the third slap, Shinji Matou finally snapped out of his daze, ignoring the excruciating pain in his buttocks, and cried out, "Grandpa took the new little sister to the basement! Stop hitting me, it hurts too much!"

Wang Bai's expression changed. Damn it, Matou Ryouken is really fast. He's about to make a move?

"Lead the way! I'll stop hitting you once I get you there!"

After saying that, he gave Matou Shinji's butt a hard slap.

Shinji Matou quickly gave directions, hoping the other person would find his grandfather and have him rescued.

Soon, Wang Bai arrived at the basement.

As soon as I entered, I saw Matou Sakura lying in a magic circle under the light.

An old man, neither human nor ghost, stood to the side, the magic loop in his hand emitting a faint halo.

"You son of a bitch!"

Wang Bai hurled Matou Shinji at Matou Tsurugi.

Matou Ryogen had already sensed the other party through the insects, but the other party arrived too quickly, and Matou Shinji, that grandson, was also quite fast in pointing the way.

It's important to know that the larger the magic trick, the more difficult it is to interrupt or pause it.

Just as Matou Ryogen paused his magic performance, his grandson smashed a weapon down on his head.

He cannot avoid it; if he does, the Matou family bloodline will have no way to continue.

Although he believed that with Matou Sakura, there was no need for other bloodlines, magicians always have a few extra preparations for their own inheritance, which made Matou Ryogen unable to avoid it and become Matou Shinji's human cushion.

Taking advantage of the opportunity, Wang Bai quickly jumped from the doorway to the next basement level and came to Matou Sakura's side.

After a quick check, Wang Bai breathed a sigh of relief. Matou Sakura had no wounds, which proved that she had not undergone any magical modifications.

"Who are you? Why have you broken into the Matou family's house?"

The other party must be an ordinary person, otherwise the surrounding barrier and the Matou family's arrangements would have blocked them.

However, it is not easy for an ordinary person to break into this place.

And their target was clearly the young girl who had just been adopted by the Matou family.

"Could it be that the Tohsaka family has changed their minds and wants to take Sakura Tohsaka back?"

"I asked tentatively," Matou Tsurugen asked.

At the same time, he made up his mind that even if the Tohsaka family wanted to bring Sakura back, he would never agree.

It's likely that he won't find such a good body again before his current body reaches the end of its lifespan.

As the magic world gradually declines, magic families within the Dayuan ecosystem will naturally be eliminated over time.

Most of the families that have survived to this day are in a similar situation to the Matou family.

So there's a reason why Tokiomi Tohsaka is so arrogant; the Tohsaka family is considered one of the most successful families in the entire magic world.

However, for Matou Ryogen, his own family was gradually declining due to his parasitic relationship with the family, and it was difficult to find a suitable candidate with the required magical qualifications from the outside world.

Naturally, Sakura Tohsaka is a resource that absolutely cannot be let go.

Wang Bai shook his head: "No, my coming here has nothing to do with the Tohsaka family."

Matou Ryouken secretly prepared a magic trick using his magical powers, while continuing to stall for time by saying, "Then why did you come here, and why did you kidnap our family's junior?"

"Junior?" Wang Bai had truly underestimated Matou Ryuken's shamelessness: "Letting a young child be eaten by insects in an insect cave? And then subjected to perverted humiliation every day? Is this how you treat your juniors?"

Matou Ryogen didn't know how the other person knew these things, since he had only made a plan and hadn't even had a chance to do it yet.

"How did you know that? Who are you?"

However, Wang Bai was too lazy to say another word to this old bug.

Matou Ryouken felt he couldn't get anything out of this young man, but it didn't matter. Once he was in their hands, he would cry and beg for death.

The magic trick had already been completed; multiple magic bullets severed Wang Bai's limbs.

To be fair, Matou Ryogen has lived for so many years, and his mastery of the basic magic of the Magic Bullet is unparalleled.

But the next second, something pierced through Wang Bai's brain, and his life force vanished instantly.

Matou Ryuken immediately realized that there was something else around him.
