Chapter 49: Disease Detection

Upon hearing Shinobu Kocho's instructions, Kanao nodded gently, her soft black hair swaying slightly with the movement.

Under her skillful hands, a room was quickly transformed, becoming tidy and comfortable.

Shinobu turned to Lin Yi and said, "Mr. Lin, please wait here for a moment. I will go check on the patients first."

With that, Shinobu left the room, leaving behind only a faint fragrance.

Lin Yi sat in the room waiting, his gaze slowly sweeping across his surroundings.

Although the Butterfly Mansion was not large in scale, every detail exuded comfort and warmth.

The furniture was arranged simply and elegantly without losing its grace; every placement was just right, creating a sense of home.

A short while later, Kanao returned. Standing at the doorway, she spoke in a soft voice, "Mr. Lin, the guest room has been prepared for you."

After thanking her, Lin Yi followed Kanao to the guest room.

"Mr. Lin, please see if there is anything else you need," Kanao asked softly once more.

"No need, this is already very good."

After waiting for a moment and seeing that Shinobu had not yet returned, Lin Yi decided to get up and check on the wards.

Walking through the corridor, Lin Yi gently pushed open the door to a patient's room.

The room was filled with a faint medicinal scent, interlaced with the fresh air drifting in from the window.

Lin Yi's gaze fell upon Shinobu, who was standing by a hospital bed, fully concentrated on examining the injuries of a Demon Slayer member.

She gently turned the member's wound, carefully inspecting every detail, fearing she might miss any sign that could lead to a worsening condition.

Hearing the sound of the door opening, Shinobu finally looked up.

Upon seeing it was Lin Yi, she gave a slight nod of greeting.

Lin Yi's eyes fell upon the young Demon Slayer lying on the bed.

The boy's left arm was gone, the empty sleeve swaying gently in the breeze, and his right eye was tightly wrapped in thick bandages, making his youthful face look heartbreaking.

Despite suffering such severe injuries, the boy appeared exceptionally composed.

He did not let out any moans of pain or complaints; instead, he lay there quietly, even wearing a smile on his face.

In his mind, Lin Yi silently activated *Disease Detection*.

In the next second, the physical condition of the young member on the bed gradually emerged in Lin Yi's vision, with all data presented clearly before his eyes.

【Left arm missing, right eyeball missing, third and fifth ribs fractured, moderate concussion】—the series of information caused Lin Yi's brow to furrow. Such injuries were by no means easy to heal.

The severity of this young member's injuries far exceeded his expectations.

"What is your name?" Lin Yi asked softly, his tone carrying a hint of gentleness and concern.

"Hideki Sato," the Demon Slayer before him said timidly. His voice was weak, yet it sounded exceptionally clear in the quiet ward.

Lin Yi nodded slightly to indicate he had heard the name.

He turned to Shinobu to request Hideki Sato's medical records and began to flip through them carefully.

A moment later, Lin Yi put the records away and said softly, "It's quite comprehensive, but one thing is missing. Have him eat more carrots; it will help with his concussion recovery."

As he finished speaking, Lin Yi gave a gentle wave of his hand, and a soft light from a healing spell instantly enveloped Hideki Sato's body.

Hideki Sato felt a warm power slowly flowing into his body, dispelling the gloom and pain within him.

His expression relaxed instantly, and his furrowed brow smoothed out.

"Thank you."

Hideki Sato was not an ignorant person and naturally understood what had happened.

【Successfully treated Hideki Sato. Talent 'Redeemer' activated. Permanently increased HP by 10 and Abyss Power by 5. Current HP: 217, Current Abyss Power: 178.】

【Gained 200 Demon Slayer Corps contribution points.】

"A concussion? What kind of ailment is that?" Shinobu looked at Lin Yi in confusion; she had never heard of such a condition in the world of *Demon Slayer*.

In the medical knowledge she had studied, similar conditions were often simply categorized as brief memory loss or headaches following head trauma, without a clear definition or classification.

Lin Yi realized then that the understanding of concussions in this world was still very limited.

"A concussion is a brain injury caused by an external impact or violent shaking of the head," Lin Yi began to explain patiently. "It can lead to symptoms such as headaches, dizziness, nausea, vomiting, and memory loss. In severe cases, it can even cause consciousness disorders or coma."

He further pointed out that treating a concussion requires a comprehensive consideration of the patient's symptoms, age, physical condition, and other factors to formulate a personalized treatment plan.

Listening to Lin Yi's explanation, Shinobu nodded in understanding while taking diligent notes.

She found that, compared to the vague descriptions in previous books, Lin Yi's words were more accurate and specific, allowing for a deeper understanding of the condition.

"I see. Mr. Lin, where did you learn so much? Why have I never heard of a concussion before?" Shinobu asked curiously.

She was quite knowledgeable regarding medical texts, but this was the first time she had heard such detailed knowledge about a concussion, which sparked a strong interest in Lin Yi's medical background.

"This condition has only recently been studied and defined in detail. I read about it in foreign medical journals; it is normal that you haven't heard of it before."

After hearing Lin Yi's explanation, Shinobu nodded, indicating she would ask someone to purchase several foreign medical journals for her to study upon her return.

Though the Butterfly Mansion did not look large from the outside, the number of wards inside was quite substantial.

In just two short hours, Lin Yi and Shinobu had jointly consulted on over thirty patients, and the injuries of every single patient could be described as harrowing.

There was never any reconciliation in the battles between the Demon Slayer Corps and the demons; every fight was a struggle between life and death.

Therefore, whenever the two sides encountered each other, fierce battles would break out until one side was completely defeated.

Just like the member Lin Yi had checked on earlier—their squad originally had eight people, but now only he remained, and his legs were also severely injured.

For the members of the Demon Slayer Corps, as long as they could slay a demon, it was the greatest victory.

They wrote a magnificent war song with their lives and blood; every battle was a brush with death.

"Alright, let's call it a day for now." Lin Yi glanced at his remaining Abyss Power, which had dropped to single digits.

Despite being somewhat exhausted, he was satisfied with today's results.

Through a day of tireless effort, Lin Yi had finally succeeded in maxing out the *Redeemer* talent and the *Life Essence of the White Rose*, while his Demon Slayer Corps contribution points had soared to over 6,000.
