Demon Slayer: The Journey That Began When I Became Yoriichi's Sister

Chapter 223 You should have a deep understanding of this.



Chapter 223 You should have a deep understanding of this.

Seeing Ikuko looking at her, Shinobu Kocho waved her hand: "No... I only helped out a little. The main work of making the medicine was done by Ms. Tamayo."

Tamayo smiled and said, "Miss Shinobu is too modest. Miss Shinobu contributed a lot to the successful completion of the potion."

The two of them pushed each other back and forth, looking quite amicable.

Yuko didn't care about their polite refusals, and her crimson eyes lit up slightly.

Tamayo has been researching drugs that weaken Muzan for hundreds of years.

It's safe to say that no one understands Muzan better than her.

Yu Zi crossed her arms and said with a sigh, "You two really did something big behind the scenes."

Yuko is so cute with her arms crossed over her chest.

Noticing Shinobu's strange expression again, Yuko blushed, her face twitched twice, and her body returned to normal at a visible speed.

Tamayo interrupted her, making her forget her current state.

"Phew... this is still the most comfortable." Yuko straightened her collar and sleeves.

A hint of regret and pity flashed in Shinobu's eyes.

Yuko stretched her body and asked Asama Sei, "Let's talk about the effects of the medicine first?"

Tamayo parted her lips slightly: "The first function is to humanize the demons."

Yuko tilted her head: "I don't think it would be enough to turn Muzan back into a human, right?"

Even though Muzan is also called a demon, he is the progenitor of demons. If an enemy can be defeated with a drug, then there is no need for them to put in any effort.

“Yes, the stronger the demon, the better it is at breaking down toxins.” Tamayo nodded slightly. “It’s impossible to turn Muzan back into a human using this kind of medicine.”

"However, during the period when the drug is in effect, it can significantly weaken Muzan's regenerative ability."

"Next up is the aging agent..."

Yuko blinked: "Wait, do ghosts age too?"

“While demons are immortal beings, they need to have enough flesh and blood to feed on.” Tamayo said, her purple eyes fixed intently on Ikuko. “I think Ikuko understands this very well.”

"..." Yuko realized that Tamayo was teasing her again, opened her mouth, and defended herself, "I... I didn't feel anything."

Really!

Just like when you're hungry and don't eat, the hunger will subside after a while.

When Yuko first started weaning from blood, she did experience intense hunger that made her feel unwell and want to eat something, but it wasn't unbearable.

“e=(′o`*))) Sigh.” Tamayo sighed softly, her purple eyes filled with helplessness.

That's how the condition worsened.

Tamayo really wanted to say, "If you feel hungry, eat," and "If you feel unwell, see a doctor," instead of enduring it like an idiot.

Ikuko: "..."

Tamayo seemed to have run out of things to say to Ikuko on this topic.

He continued, "In short, the aging agent can significantly weaken Muzan's combat abilities, both in terms of strength and speed."

"Furthermore, based on my preliminary assessment of the effects of this drug through tests on malignant cells, it should be able to achieve the effect of aging fifty years in one minute."

This is a bit extreme; she hasn't eaten for two hundred years, yet Tamayo says she'll be dead soon.

If Muzan were to actually take that hit, he'd probably split open on the spot.

"Then it acts as a deterrent to division."

"..."

Tamayo said that it couldn't crack even a little bit.

Having personally witnessed Muzan's escape from Yoriichi, Tamayo understood one thing.

That is, in order to kill Muzan, Muzan's ability to split must be rendered ineffective.

They could no longer exert absolute dominance over Muzan like Yoriichi could.

If the only option is to stall, then Muzan's ability to split must be suppressed.

Otherwise, it would have been difficult for them to hold out until dawn.

Muzan is not some straightforward person who doesn't know how to back down; he's a rat in the gutter, and he will run away without hesitation whenever there is danger he can't handle.

Don't think of Muzan as the kind of enemy who would fight you honorably to the very end.

"Finally, the cell-destroying drug will take effect after the first three effects are broken down by Muzan, further weakening Muzan's power."

Yuko looked a little dazed, as if she hadn't understood what Tamayo was saying.

It was like someone bringing you a pillow when you're sleepy. Before coming here, she was thinking about how to hold off Muzan in the final battle.

After arriving.

Tamayo said, "I will help you."

She really is helping!

Just hearing about the effects of this medicine sent chills down Yu Zi's spine—it could cause her to become human again, age, and have her cells destroyed.

That's incredible! Tamayo!!

Yuko's eyes lit up: "Then I'll create the opportunity and inject the drug into Muzan..."

Before she could finish speaking, Tamayo calmly interrupted, "Ikuko..."

"Ok?"

Tamayo's gaze remained calm: "I don't think you're that naive, are you?"

Yu Zi's pupils contracted slightly, and the look of joy on her face instantly froze.

Tamayo said calmly, "Muzan won't give us the chance to inject the four kinds of medicine."

These four effects cannot all be achieved with a single drug. One time is fine, but after being hit by it once, Wuzan will be more cautious.

Ideally, all four potions should be delivered into Muzan's body in an instant, and the best way to do this is to make Muzan absorb the four potions without his knowledge.

However, this means that the holder of the potion would face the risk of directly confronting Muzan.

And the only ones who can take this risk without affecting the subsequent battles are...

Yuko's eyes narrowed slightly: "Tamayo...you wouldn't be thinking of..."

Tamayo did not respond, her eyelids drooping slightly.

Yuko wasn't stupid; she quickly figured out Tamayo's plan.

After a moment of silence, Yu Zi nodded slightly: "I understand, I will create opportunities for you."

An opportunity to get close to Muzan.

Upon hearing this, a smile reappeared on Tamayo's stern face.

Ikuko...

"But... after you inject the drug into Muzan's body, I will find a way to send you off the battlefield."

Tamayo was taken aback, and before she could say anything, Ikuko spoke again.

"Don't think that doing that is atonement. If we can kill Muzan and create these drugs, you will have already atoneed for your past sins."

“Yuko…” Tamayo’s eyes widened slightly.

Just as Tamayo understood Ikuko, Ikuko also understood Tamayo.

She didn't believe that killing one person and then saving another would erase her past sins.

However, I don't think that someone who saved tens of thousands of lives should be subjected to severe punishment without any leeway.

The calamity brought about by Muzan, known as the demons, has claimed the lives of countless people.

Moreover, she is actually quite selfish.

Even though Kokushibo has harmed too many innocent people, she will still feel a trace of kinship towards him, rather than righteously severing ties with him.

Not to mention Tamayo, who was deceived by Muzan.

No, or rather, when something like this happens to one's own relatives or friends, no one can remain indifferent.
