Awaken the Sharingan, kill Muzan and open your Mangekyō!

"Mina, find me the headquarters of the Demon Slayer Corps!"

"Next time, I will go out myself."With his teeth almost broken, Muzan Kibutsuji roared and gave orders to Naruto.

At this moment when there are only a few upper-rank demons left, he plans to take the risk and go out himself.

So what if it's the Sun Breathing?

He just doesn't believe that Uchiha Isha will be the next Tsugikoku Yoriichi!

Muzan Kibutsuji"hypnotized" himself in his heart.

"Yes, yes!"

After receiving the order from her immediate superior, Muzan Kibutsuji, the girl in the Infinite Castle was once again trembling with fear.

Judging from the tone of Muzan just now, if she couldn't find the whereabouts of the Demon Slayer Corps in a short time, she felt that she might be the only upper-rank demon who would die at the hands of her immediate superior, Muzan. No matter how valuable she was, she would be killed by the enraged Muzan Kibutsuji.

"Why would the blood demon art of the dead Douma appear on the battlefield where Hantengu and Gyokutsuchi are?"

"Could it be that the Swordsman of the Sun-Breathing was also there at that time? Was this the power of the eyes of the Swordsman of the Sun-Breathing?"

"Or……"

After giving the order to Naruto, Muzan Kibutsuji calmed down a little and thought about the anomaly he had discovered.

Since Douma's blood demon art appeared, there must be only two reasons.

Either Douma's blood demon art was obtained by Uchiha Isha in some way, or Douma was not dead yet and betrayed himself. Of these two possibilities, the latter is very unlikely.

Even if Uchiha Isha's eyes were powerful, it should be impossible for him to"deceive" himself so perfectly and let himself see the illusion of Douma's death. He even helped Douma escape from his control and betrayed himself.

On the contrary, the former seems more likely!

"What is the origin of those eyes?"

Thinking of the former, Muzan Kibutsuji frowned and pondered this unsolved mystery again.

If he fights with Uchiha Isha in the future, Uchiha Isha's eyes will definitely be the key point.

……

Demon Slayer Corps Headquarters!

This is more than a month after the battle of the Swordsmith Village.

In this month, everything is very peaceful.

Not to mention the upper-rank demons, even ordinary demons have rarely appeared everywhere.

This also made the nine pillars of the Demon Slayer Corps and other swordsmen unusually idle.

And in the eyes of Uchiha Isaka and Ubuyashiki Yoya and others, it was more like the death of Hantengu and Gamatsubo triggered the vigilance of Muzan Kibutsuji.

The eve of the final war may be coming.

Therefore, more than half a month ago.

Ubuyashiki Yoya simply ordered the swordsmen of the Demon Slayer Corps to gather and held an intensive training.

The purpose is to let the nine pillars continue to hone each other, strive for all members to master the transparent world, and let them drive the strength of ordinary swordsmen to grow.

Therefore, Uchiha Isaka also became one of the"instructors" to help train the swordsmen of the Demon Slayer Corps.

He felt a little troublesome about this.

He simply used the pupil technique of Hantengu to differentiate an avatar to help guide the ordinary swordsmen of the Demon Slayer Corps.

As for himself, he was slacking off in the Butterfly House.

It can't be said that he was lazy. At least

, he was guiding Kanao.

He even guided Tanjiro, who had just returned from his hometown, Okutama Kumodoriyama.

Under his guidance, Kanao and Tanjiro are now able to open the transparent world, which is a step further.

Speaking of Tanjiro, we have to mention the blue spider lily.

Maybe it was a coincidence, or it was a blessing from heaven.

Tanjiro, who returned to Okutama Kumodoriyama with his sister Nezuko, found the blue spider lily near his hometown under Nezuko's guidance.

And it was a blue spider lily that was in full bloom and had not yet withered.

With this surprise, Tanjiro didn't even have time to clean his house.

He directly transplanted a few blue spider lilies into flower pots, and then rushed back to the Butterfly House.

Although the change of the growth place made the blue spider lily somewhat sluggish, fortunately, when it was sent to Tamayo and Kocho Shinobu, the blue spider lily had not withered after all.

This also gave Shinobu Kocho and Tamayo the opportunity to study the blue red spider lily.

Tamayo was also able to research the drug that could turn ghosts into humans.

Also because of the existence of the blue red spider lily.

In the end, Tamayo, Yushiro, and even Nezuko, who was already developing in the direction of a"perfect ghost", overcame the weakness of sunlight and became"perfect ghosts".

However, their"perfect ghost" status is somewhat different from Uchiha Isha's"perfect ghost".

Even though they no longer need to replenish their needs by taking a small amount of blood or sleeping, they can eat ordinary food like ordinary people to meet their needs.

But their looks and appearance still retain some characteristics of ghosts.

Fortunately, these are harmless.

Tamayo and the others don't care about it.

The same is true for Tanjiro.

In comparison, he is happier about his sister Nezuko's"recovery".

……

A few days later

, Uchiha Isha, who was enjoying the moon in the Butterfly House, was summoned by Ubuyashiki Yoya.

It wasn't just him.

The other nine pillars were also summoned by Ubuyashiki Yoya.

"Ladies and gentlemen, please forgive me for calling you in so late at night."

"But it seems that our chance has come!"

In the living room, Ubuyashiki Yoya said to Uchiha Isha and his party in front of him.

During this period, Ubuyashiki Yoya has also undergone significant changes.

He was originally suffering from illness and could hardly get out of bed, but his condition has improved.

The most direct evidence is that the purple scars on his face have not only not spread further to the whole body, but have also subsided.

The half of his face that was previously covered by scars has now subsided above the forehead.

Therefore, Ubuyashiki Yoya's eyes, which were originally blind, can see again.

And the reason for Ubuyashiki Yoya's improvement?

Among them, there are both Tamayo's credit and Uchiha Isha's credit.

Through the blue red spider lily, Tamayo has developed a method to help Ubuyashiki Yoya slightly Recovery medicine.

As for Uchiha Isha, he used the eye technique Mei to exert his vigorous vitality on Ubuyashiki Yoya.

This also helped Ubuyashiki Yoya to get better.

With the two of them, it would be difficult for Ubuyashiki Yoya not to recover.

However, this is only temporary.

As long as Muzan Kibutsuji is not eliminated, Ubuyashiki Yoya's condition will continue to become more serious until he is deprived of his life.

However, it is worth being happy that Ubuyashiki Yoya has more time left.

He may be able to see the day when Muzan Kibutsuji is destroyed by the Demon Slayer Corps.

This also made Ubuyashiki Amane and Ubuyashiki Yoya's children extremely excited and excited.

At the same time, they are also very grateful to Uchiha Isha and Tamayo.
