Awaken the Sharingan, kill Muzan and open your Mangekyō!

Really good!

Uchiha Ixia was very satisfied with the research progress of Tamayo and Kocho.

This was much faster than she had imagined.

In the original history, Tamayo and Kocho had worked together for at least several months.

It seemed that getting the blood of the upper-rank demon in advance had brought Tamayo a big breakthrough.

This also made her and Kocho's progress even more rapid when they started to work together.

"As for the first kind of poison, I might be able to provide some help."

After thinking of something, Uchiha Isha said to Tamayo

"Oh?"

Tamayo was very surprised when she heard that.

Could it be that Uchiha Isha is also an expert in medicine?

But this first drug that can turn a demon into a human cannot be researched out by superb technology and rich experience.

She was able to find the clues thanks to Tanjiro's sister Nezuko.

The other party's physique is very special.

Not only can she get rid of Muzan Kibutsuji's control on her own, but she also does not need to maintain her own needs by eating a small amount of blood like she and Yushiro.

The most important thing is that Nezuko's blood is still changing all the time.

Judging from the current changes.

She even thinks that Nezuko may be able to overcome the weakness of sunlight in the near future and become the"perfect demon" that Muzan Kibutsuji has been thinking about.

If Nezuko really does this, perhaps she can also research drugs that turn demons into humans based on Nezuko's blood.

And at that time, Nezuko may also be an important bait to attract Muzan Kibutsuji.

Muzan Kibutsuji will not miss a demon who can overcome sunlight. He will do everything possible to find Nezuko and eat her, so that he can also overcome sunlight.

"Nezuko's physique is very special, and the reason for her special physique is that she is the descendant of a user of Sun Breathing."

"And...she once took blue Higanbana."

Uchiha Ixia revealed this secret.

The original work did not mention that Nezuko had eaten blue Higanbana.

But in some comic book cover pages, there are scenes of Nezuko's childhood.

And near Nezuko, there are what appear to be blue Higanbana.

It is very likely that Okutama Kumotori Mountain where Tanjiro's family lives is a suitable place for the growth of blue Higanbana.

As for Nezuko, she may have eaten Higanbana as a wild vegetable because of her family background.

This may also be one of the key factors that enabled Nezuko to overcome the sunlight.

It can be said that this is not only because Nezuko is the descendant of a Sun Breathing user.

Unless she practices Sun Breathing like Tanjiro, it is possible to quickly overcome the weakness of sunlight.

""Blue Blossom of the Other Shore!"

Upon hearing this name, Tamayo was deeply moved.

Even her body was shaken violently.

Having been with Muzan Kibutsuji for so many years, she knew what Muzan Kibutsuji wanted and needed the most.

It was the blue Blossom of the Other Shore.

The blue Blossom of the Other Shore is the"holy object" that allows demons to overcome the sun.

But no one has ever seen the blue Blossom of the Other Shore, and the conditions for its growth are unknown.

This is why Muzan Kibutsuji has never discovered the existence of the blue Blossom of the Other Shore after thousands of years.

"Yes, blue Higanbana!"

Uchiha Isha nodded.

The reason why Tamayo was able to research a drug that turns ghosts into humans may be because Nezuko, who had eaten the blue Higanbana, overcame the sunlight and her blood changed.

It was this critical change that allowed Tamayo to discover the possibility of a drug that turns ghosts into humans.

Otherwise, Tamayo could only restore consciousness to the people who were turned into ghosts and survive by eating a small amount of blood.

"Okutama Untorii Mountain, where Tanjiro's family lives, seems to be a suitable place for blue spider lilies to grow"

"The blue spider lily blooms only for two or three days a year and then quickly withers."

"If it were Tanjiro, maybe he would know the whereabouts and blooming time of the blue spider lily"

""With the blue Higanbana, it should be able to help your drug research."

Uchiha Ixia said.

That being said, there is actually a more efficient way.

That is, he directly uses the power of the Sharingan to get it from Nezuko's mind.

But there is nothing to do anyway, Tanjiro has finished his special training and continues to carry out the mission.

Taking Nezuko back to her hometown to have a look is also a good thing for them.

"I didn't expect such an amazing coincidence.……"

Tamayo opened her mouth slightly, her face showing even more shock.

The place where the blue spider lily grows is actually in Tanjiro's hometown

"It only grows during the day, and only for two or three days. No wonder……"

Tamayo smiled bitterly.

Now, she understood why she and Muzan Kibutsuji could not find the blue spider lily.

During the day, that is a time when demons cannot appear at all.

Not to mention, the time when the blue spider lily appears is so short.

If Muzan Kibutsuji wants to get the blue spider lily, he may have to cooperate with humans.

And this is impossible for Muzan Kibutsuji.

Not to mention that he regards humans as blood food and looks down on them.

He also doesn't want his existence to be known to too many humans, so as to avoid the appearance of someone like Yoriichi Tsugakuni who puts him in danger.

"Then I'll ask Tanjiro later!"

Tamayo nodded after adjusting her mood.

If she could really get the blue spider lily, it would definitely be a blessing for her.

It was one thing for her and Yushiro to overcome the sunlight, but the key was to research a drug that could turn Muzan Kibutsuji into a human.

Even if they were unlucky and couldn't get the blue spider lily, the roots, stems, leaves, etc. of the blue spider lily might be able to work. If it really didn't work, they could wait for the day when Nezuko, who had eaten the blue spider lily, overcame the sunlight.

That day shouldn't be far away.

"correct!"

"You can also study my blood, maybe it can also help."

Uchiha Isha suddenly said to Tamayo.

This was also something he suddenly thought of.

As a user of the Sun Breathing who has activated the stripes, his blood should also be able to play a significant role.

Not to mention, he has obtained the energy of the ghost and is evolving towards the direction of the"perfect ghost".

His blood can help Tamayo research the drug that can turn ghosts into humans.

"Is it okay?"

Jade was a little moved when she heard this.

Speaking of which, she really hadn't studied the blood of the Sun Breathing user.

Perhaps, this could be used as a substitute for the blue Higanbana.’

"Of course!"

Uchiha Isha said affirmatively.

After saying that, he rolled up his sleeves and motioned Tamayo to draw blood.

Seeing Uchiha Isha like this, Tamayo was no longer polite.

She took out a small syringe and drew a small tube of blood from Uchiha Isha.

Although it was a little less, it was enough for research.

Moreover, she was embarrassed to draw too much blood from Uchiha Isha, fearing that it would affect Uchiha Isha.

After all, Uchiha Isha is not a ghost.

Even if the impact of losing some blood is beneficial to the human body, it will take quite a while to recuperate.

The battle with the upper-rank ghosts is still going on, but it is not time to rest.

Seeing that Tamayo only drew so much blood, Uchiha Isha naturally guessed the reason.

He did not take the opportunity to tell Tamayo about the abnormality of his physique, so as to let Tamayo continue to draw.

Anyway, it is just for research, and it will not be too late to let Tamayo draw some more when it really works.
