Delicate Illness Extraction Technique

"Well done! Young man, the youth who uses Thunder Breathing, you must be the Suzuki Mufeng mentioned in the recommendation letter from Kuwajima. To be able to eliminate Lower Rank Six in such a short time, even while heavily injured, you are already a formidable swordsman. Are you certain you don't want to continue refining your Thunder Breathing, but instead choose to practice Flame Breathing?"

"My current Breathing Style does not suit me. I wish to witness more Breathing Styles to create one that is perfect for me! Only then can I further refine myself and one day sever the head of that Demon King, Muzan Kibutsuji!"

"Excellent, such drive, young man! Once the members of the Butterfly Mansion arrive at the village to treat the villagers, we shall return to the Rengoku Family together, and I will teach you Flame Breathing without reservation!"

Kyojuro Rengoku had barely finished speaking before he rushed toward the village. The effects of Kamanue's Blood Demon Art: Corrosion had not yet dissipated, making the situation extremely dangerous. He had to return to stand guard and prevent other demons from taking advantage of the chaos before the Flower Hashira and her team arrived.

Suzuki Mufeng exerted force through his legs, his body following Kyojuro Rengoku like an arrow released from a bow. No matter how much the Flame Hashira increased his speed, Suzuki Mufeng remained right behind him, never falling behind.

Such speed must be the result of grueling effort in Thunder Breathing. If he continues to refine it, he will surely become a Hashira capable of standing on his own in time. Such a gifted youth—I must guide him onto the right path!

The two soon arrived at the village, and the scene before them was unbearable. The plague had ravaged the people, leaving them unrecognizable; small, swollen bumps covered their bodies, punctuated by black spots that looked like honeycombs. Anyone with trypophobia might have been frightened to death at the sight.

This was the plague toxin derived from Kamanue's Blood Demon Art: Corrosion.

This is a method that never appeared in the original story. It must be a change caused by me, a translocator.

"Damnable demon, not even letting people rest in peace after death. Flame Hashira, when exactly will the members of the Butterfly Mansion arrive?"

"Stay calm, young man. All we can do now is wait here; we must not add to the chaos."

Though Kyojuro Rengoku said this, his hands, crossed over his chest, were clenched into tight fists, betraying his inner turmoil.

As a teenager who had once lived in a peaceful era, Suzuki Mufeng could decapitate a demon without hesitation, but facing these villagers wailing in agony, the visual impact was something he could not simply ignore.

The reality is different from what I saw on screen. My conscience is condemning me; I must do something.

Can the bubbles of Soft & Wet strip the virus from their bodies? Or wait—didn't I share memories from the ninja world yesterday? Didn't he mention medical ninjutsu?

In the end, Suzuki Mufeng chose the Delicate Illness Extraction Technique as the safest method. He would save the abilities of Soft & Wet for experimenting on demons.

"Flame Hashira, I possess a form of onmyodo that might be able to treat these villagers. Please, let me try. Do not be surprised by what you see."

"Suzuki, do not push yourself. The best we can do is stand guard here and wait for our companions from the Butterfly Mansion."

Suzuki Mufeng stepped past Kyojuro Rengoku and walked straight toward the village behind him. Kyojuro Rengoku did not stop him, for he saw the burning fighting spirit in Suzuki Mufeng's eyes.

Why not let him try? Perhaps it will truly be effective. As a Hashira, I should trust my companions unconditionally!

"Mommy, my stomach hurts so much, and I can't see anything. Am I going to die?"

"How could that be, Ryota? You just have an upset stomach; you'll be fine if you hold on. The big brother over there has already called for a physician. Promise Mommy you won't fall asleep. Once the physician comes and you take your medicine, Mommy will buy you candy, okay?"

The mother sitting on the ground already had deep black spots on her exposed wrists and chest. Her face was pale, bloodless, and drenched in cold sweat, yet she gritted her teeth and held her child tightly, masking the weakness in her voice to encourage him.

"Mommy, I'm so sleepy."

"Ryota, you can't fall asleep. Pinch yourself, and you'll feel more awake. Ryota, don't fall asleep, please... don't leave Mommy all alone."

Ryota's trembling eyelids were the final straw that could crush this mother at any moment. If the child passed away, the mother's will to live would vanish with him.

Anyone, please, save us.

"The child's condition is critical. Let him in; I have a way."

Suzuki Mufeng used bubbles from Soft & Wet to create a relatively isolated space, only then daring to enter the plague-ridden village.

Suzuki Mufeng's appearance was like a ray of light. The mother did not hesitate to send her child toward this strange man standing inside the bubble; it was the last lifeline she could reach.

Ignoring the risk of infection, Suzuki Mufeng crouched down to examine the boy carefully. Fortunately, during his months in the ninja world, Mufeng Uchiha had been studying medical ninjutsu. He wasn't exactly a scholar, but he knew a thing or two.

"B-rank ninjutsu, Delicate Illness Extraction Technique. Even Hokage Mufeng never used this; whether I succeed or not depends entirely on me."

Unable to use a Chakra Scalpel, Suzuki Mufeng had to make do with what was available. Fortunately, he had prepared cutlery; he could use a small knife, first treating it simply with fire.

Even with the shared memories, the chakra within Suzuki Mufeng's body was far less than that of Mufeng Uchiha. To handle the situation ahead, every step had to be calculated with precision.

He activated his Three-Tomoe Sharingan, sensing the root of the poison. It was all in the arms. This technique of Kamanue's spread through contact, and the point of contact was where the toxin was most concentrated.

He couldn't help but marvel at the bizarre nature of these Blood Demon Arts. The Infinity Castle alone was already absurd enough; that Muzan Kibutsuji could still lose with such a strong hand was a total disaster.

"Focus. Excise the affected area, extract the toxin, and heal the damaged tissue. Mufeng, you can do this."

Taking a deep breath, Suzuki Mufeng began.

Throughout the process, the mother watching from the side didn't dare to breathe, and Kyojuro Rengoku, along with others suffering from the plague, stared intently at them.

Extracting the toxin, healing the injured areas—every step was performed with extreme caution.

Time seemed to lose all meaning until, finally, Suzuki Mufeng closed the incision he had made.

"He is out of danger, but the poison isn't completely cleared. You must wait for my companions to arrive with the antidote. Mother, please endure for a little longer; the child has just been saved and cannot be reinfected."

Suzuki Mufeng prepared to take Ryota out, and fortunately, his mother was reasonable and did not make things difficult.

"Flame Hashira, I need a clean place to house the patients I have treated. When the companions from the Butterfly Mansion arrive, remember to have them check on them, as my treatment is incomplete."

"Leave it to me! Go ahead and do your work, young man! Do not worry about them."

After handing the child to Kyojuro Rengoku, Suzuki Mufeng resolutely returned to continue treating the others.

"Madam, I will treat you next so you can go and look after Ryota."

"Okay, thank you, truly—thank you..."

"Physician, I'm next, I'm the one after her."

"Physician, please look at my father first."

Suzuki Mufeng did not stop his hands until the companions from the Butterfly Mansion arrived. His chakra and physical strength had long been exhausted, and he had been relying solely on his willpower. Only when he saw the Flower Hashira, Kanae Kocho, and the others take over did he finally collapse, losing consciousness.
