From Becoming the Master of Monsters

What Yuuto threw to Ubuya Shiki Yōya was actually the low-quality demon power crystal he exchanged at the prestige store.

The function of this thing itself is to increase the monster power. Of course, for a monster of Yuto's level, the increase in monster power is almost negligible, so he has always used it as a recovery item.

But for ordinary people or low-level monsters, the increase in monster power from inferior monster power crystals is still considerable.

Yuto's idea was also very simple. He could feel that there was another force in Ubuyashiki Yōya's body that was destroying his body and consuming his vitality.

When ordinary people take low-quality demon power crystals, their bodies will also be eroded by demon power. In other words, if Ubuya Shiki Yaoya takes demon power crystals, a wave of demon power will enter his body.

And Yuto felt that Ubuya Shiki Yaoya's body was already eroded by the curse. If the evil power was added at this time, it might be possible to fight poison with poison.

Both forces want to erode Uyashiki Yoshiya's body, so the collision is bound to cancel out.

Of course, when throwing the demon power crystal to Uyashiki Yoshiya, Yuto also said that another situation might occur.

That is because the two forces collided too fiercely, causing Uyashiki Yōya to die faster!

This is my return gift for the Nichirin Knife. Of course, it's up to you whether you want to eat it or not.

In fact, Yuuto didn't even need to come up with inferior demon power crystals at the beginning. After all, Ubuyashiki Yōya had already agreed to his request before.

It's just that the courage and open-mindedness shown by Ubuyashiki Yōya before really made Yuto feel good about him, so he gave him the so-called return gift at this time.

My lord, you can't eat this randomly. We can think of other ways to deal with your physical problems.

But if anything goes wrong, the entire Demon Slayer Squad will be completely destroyed...

Jiuzhu looked at the purple crystal held by Uyashiki Yōya with a nervous expression on his face, strongly hoping that his lord would think twice.

As for Ubuyashiki Yaoya, who was holding the purple crystal in his hand, his eyes were shining with a light he had never seen before.

In response to Jiuzhu's persuasion, Ubuyashiki Yaoya could only show a wry smile.

Looking for other options? If their clan's problems could be solved, he wouldn't have to work so hard.

The Ubuyashiki clan is a cursed clan. Ubuyashiki Yaoya has been frail and sick since he was a child. This is not his problem alone, but the same is true for his entire clan.

The Uyashiki clan actually has a blood relationship with Onibatsuji Muzan, and after Onibatsuji Muzan became the first evil spirit thousands of years ago, their family's bloodline was also cursed.

All children born in the family will be born weak and sickly, and most of them will even die immediately after birth.

The reason why Ubuyashiki Yoshiya is confident in the offset method proposed by Yuto is because the Ubuyashiki clan uses very similar coping methods to avoid severing their bloodline.

In order to prevent the bloodline from being cut off, the Uyashiki clan in the past generations would marry girls from the Priest clan to resist the curse with the power of light.

As for the Uyashiki clan who did this, their lives are indeed longer than before, but even so, there are almost no people among the Uyashiki clan who can live beyond the age of thirty.

Ubuyashiki Yoshiya is 23 years old this year. He can also feel that his body is indeed getting weaker and weaker. He has had enough of this life where he can't even swing a knife, so when he learned that there was a way to get rid of the current situation, he The mood is naturally exciting.

At the same time, he didn't feel that Yuuto meant to harm him. Just as the other party said, Ubuyashiki Yōya also knew that he was about to die soon.

Therefore, there is absolutely no need for Yuuto to do anything unnecessary, as this will only make him the Pillar of the Demon Killing Team.

Holding the purple crystal in his hand, Ubuyashiki Yoshiya finally showed a firm expression and said to the nine pillars in front of him: If I die, my position will be succeeded by my son Ubuyashiki Teriya.

And no one of you is allowed to make things difficult for Tianshangyuan Yudou, because this is my own choice.

After saying this, Ubuyashiki Yaoya decisively swallowed the purple crystal in his hand.

Just like the courage he showed before, this seemingly weak man didn't even hesitate when faced with a choice.

As soon as the purple crystal entered his mouth, Uyashiki Yaoya found a stream of heat pouring into his body instantly, and the intense pain instantly made him clenched his fists.

The face that was originally disfigured due to some reasons has now become more ferocious, but Hashira in the Demon Slayer Squad does not have the slightest dislike. At this time, he is worriedly paying attention to the changes in his lord.

What are the chances that the purple crystal you gave to my lord will successfully solve my lord's physical problems?

At this time, Tomioka Giyu's expression could no longer maintain his previous cold attitude, but he looked at Yuto anxiously and asked.

About 50%. If it were me, I would probably take a gamble. After all, with his physical condition, he can only live for another year or two at most. But I didn't expect him to swallow it so decisively. It seems that he also hates himself from the bottom of his heart for being unable to do anything.

One more thing I want to correct is that the demon power crystal can only temporarily offset the effects of the curse, but cannot completely eradicate it.

Because the energy contained in the crystal is limited and is rootless, the curse will also break out again over time.

And just as Yuuto was explaining to Tomioka Giyu, Ubuyashiki Yōya finally came to his senses.

At this time, Ubuyashiki Yoshiya felt that his body was in better shape than ever before. When the other Hashira were supposed to help him, he actually stood up alone.

Then he squeezed his fist and punched the wooden door next to him. The powerful force actually penetrated the wooden door several centimeters thick!

Ubuyashiki Yōya's behavior also frightened the nine pillars beside him, but then their faces quickly showed ecstasy.

Breaking through a wooden door may not be a big deal for them, and even an ordinary person with a little training can do it.

But the person who did this was their lord Uyashiki Yōya, which surprised them.

Because even if Ubuyashiki Yoshiya was in good physical condition before, he could only swing the sword a few times, but now Ubuyashiki Yoshiya's physical fitness is obviously better than that of ordinary people.

It seems that I made the right bet. The crystal just now not only offset the curse on my body, but also caused me to undergo a transformation!

Ubuyashiki Yoshiya was in an unprecedented mood at this time, and even now he wanted to pick up his own sword and swing it happily.
