Demon Slayer: My breathing technique went awry after Nezuko pushed me down.

"Look what I've done to myself in order to deal with you."

"Even if you're my opponent, shouldn't you feel sorry for me, bleed a little, and help me recover?"

Muzan was shocked. What... what kind of outrageous words were these?!

He committed evil for a thousand years.

People who have been eating for a thousand years.

I have never come up with such shameless words.

What do you mean by "you did this to get back at me"?

What do you mean I should feel sorry for you?

What do you mean by using my blood to replenish you?

Ignoring Muzan's terror, Shirakawa Yu muttered to himself, "One hundred and eighty times, who can withstand that?"

At this moment, his system display showed a base stat bonus of '18020%'.

"Last time, it was only thirty times."

"Does You Guo have so many girls now?"

"Seriously, I almost burst."

As he slowly exhaled, the crimson on his body gradually faded, and his spirits shifted from excitement to a state of lethargy.

That terrifying sense of oppression disappeared.

As a result, Shirakawa Yu himself felt much more relaxed.

He looked at Muzan with a grin.

She even reached out and patted his shoulder, which was covered in red arrows.

"Don't worry, it will be soon."

"After all, leave slips aren't that effective. You won't have to endure it for long before you're free again."

"What...what do you mean...you..."

Bai Chuanyu smiled and shook his head. "Be good, talk less. Look at you, your lips are all white."

As he said this, his eyes were fixed on the two blood-draining filters inserted into Muzan's neck, operating at full power.

And blood gushing out like a fire hydrant.

Below the filter, two round beakers were now covered with a thin layer of blood essence.

Shirakawa Yu's eyes grew increasingly expectant.

These are the foundations of the future vampire clan!

"Kawabata, do me a favor."

Just as Shirakawa Yu was daydreaming about the future, Tamayo reached out and nudged him.

Shirakawa Yu turned around and looked at Tamayo behind her, along with the two large jars of leave slips in her hands, plus two tubing tubes and needles.

What's going on here?

Tamayo had Shirakawa Yu hold the medicine while she connected the needle and tubing to the container.

Then, he silently watched Muzan's wrist.

Bai Chuanyu immediately understood and withdrew some of the Crimson Arrows.

Muzan's two wrists were exposed.

"What are you trying to do?! What are you trying to do again?!"

Amid Muzan's screams, Tamayo slowly pushed the needle into Muzan's vein.

"After thinking about it, I realized that instead of injecting the medicine one injection at a time with varying dosages, it would be better to maintain a consistent dosage."

"We should be able to buy as much time as possible."

Shirakawa Yu looked at everything Tamayo had done, then at the jar in his hand, and his eyes widened instantly.

"Good heavens, an IV drip!"

Tamayo turned around, took the jar, held it high, and winked at Shirakawa Hajime.

"Is it not allowed?"

Bai Chuanyu opened his mouth, then shook his head.

"of course can."

As they spoke, the black stone beneath their feet slowly rose and transformed into two pillars.

There are two grooves in the middle on each side, just enough to hold the jar.

This also saves Tamayo from having to keep putting it off.

"only......"

He glanced at the filter with some concern.

"Won't there be any problems with the essence and blood produced this way?"

Tamayo smiled. "Don't worry, I'll make sure everything you put in your mouth is safe."

"This medicine has a limited shelf life; it will expire on its own soon. Besides, there's a filter, isn't there?"

Upon hearing this, Shirakawa Yu didn't say anything more.

After all, this is the only option left.

Will having blood drawn while receiving medication have any impact?

who cares!

Anyway, Muzan's medicine can't be stopped!

"Let me go!!! Let me go!!! I don't want a shot, I don't want to—waaaaaah!"

Muzan was still howling, but Shirakawa Yu, annoyed, used the Crimson Arrow to gag him again.

He turned sideways and approached the two flasks.

Staring at the filtered blood, dripping down drop by drop.

Time passed by, second by second.

The blood in the bottle kept accumulating.

The filtered waste blood gushing out from both sides was almost forming a river.

Meanwhile, Muzan's struggling whimpers grew fainter and fainter.

The collection of essence blood has almost come to a standstill.

"almost."

Looking at the two large bottles filled with essence blood, Bai Chuanyu reached out and twisted off one of them.

Tamayo quickly took out a new one and placed it underneath to catch the food, thus avoiding waste.

Meanwhile, Shirakawa Yu, carrying a beaker, slowly walked up to Muzan.

He raised his hand and made a toasting gesture towards Muzan.

"As a sign of respect, I'll drink first!"

Without saying a word, he stood under Muzan's almost bulging eyes.

He tilted his head back, poured the beaker in his hand, and drank it all in one gulp!

The next second, a tremendous force exploded within his body!

The system in his mind was flashing red lights frantically.

[Warning! Warning! Host detected absorbing large amounts of unknown essence blood. The system is rapidly scanning.]

[Scanning in progress...]

[Scanning in progress...]

[Scan complete. Blood essence composition and ability identified: Kibutsuji Muzan, cell manipulation.]

[WARNING! This capability exceeds the system's security conversion standards and may cause unforeseen consequences.]

[Host, are you sure you want to absorb this?]

What are you waiting for?!

'absorb!'

[Ability extraction in progress, please wait...]

[10%.......20%.......30%.......40%.......]

The percentage displayed in the system message kept rising.

Just when it seemed like we were almost halfway through, the beaker in my hand was empty.

Without any hesitation, Bai Chuanyu pulled out another bottle and put it to his lips.

【50%.......60%.......70%.......80%.......90%.......91%.......92%.......】

The extraction process was slowing down, but the beaker in Shirakawa Yu's hand was already empty.

Don't stop! Don't stop!

It was so close!!!

However, even though Shirakawa Yu poured all the newly collected drops into his mouth in that short time, leaving none behind.

The number remained at 98 percent...

Don't stop! I'm blanching it!!!

It's so close!!!

[Warning! Extraction terminated. Please continue absorbing, otherwise the extracted ability will be incomplete and unknown changes will occur!]
