Ye Lingling's Nine-Hearted Begonia was indeed a "miracle" in medical treatment. Lin Yang understood this better than anyone.
Precisely because of this, he had to make things clear upfront. Once the healing effect of the Nine-Hearted Begonia appeared in the Butterfly House, what would be the consequences?
Those plagued by injuries and illnesses would swarm over like sharks smelling blood! The Butterfly House's reputation would also spread throughout Heaven Dou City overnight.
And then? Then the Butterfly House would gain no benefits. The forcibly inflated fame would only become a burden on the Butterfly House's back.
There were endless patients, and people's hearts were biased. If you used the Nine-Hearted Begonia to save a severely ill patient, of course he would be grateful and want to worship you.
But if you made another patient with a milder condition take medicine and recover slowly, would he feel gratitude? Or resentment?
Of course, Lin Yang wouldn't say these words out loud. But that thorn would remain in the heart, festering, rotting, and eventually turning into one of countless malicious words.
"Unequal distribution causes more resentment than scarcity," "a cup of rice brings gratitude, a bushel brings enmity"—how many times had such things happened throughout history?
As for making money? Hah! Of the people who came here for treatment, eight out of ten were commoners. How much money could they have? Not only would Lin Yang not earn money, he would have to subsidize it.
Only after selling the Blood Coagulation Powder and Antidote did the Butterfly House achieve self-sufficiency.
Moreover, using soul skills for treatment wouldn't help Ye Lingling's own cultivation. This wasn't a cultivation world where healing people accumulated merit. Frequent use of her martial soul would only make the Nine-Hearted Begonia be taken for granted as a tool and might even delay Ye Lingling's training. It would be more loss than gain!
Therefore, Lin Yang did not want Ye Lingling to expose her martial soul. Even if she had to use it, it could only be done privately and must never be discovered by others.
After listening, a strange light flashed in Ye Lingling's eyes. She didn't refute him, only asked, "Then what should I do?"
"For the next few days, follow Catherine. She is already very skilled at handling ordinary injuries."
Lin Yang paused, then added, "I remember the Ye Clan also practices medicine. How is your learning?"
Under her veil, Ye Lingling's face stiffened for a moment, and her earlobes turned slightly red.
After a long silence, she lowered her eyes, her voice as quiet as a mosquito. "I… I don't know how."
She had the Nine-Hearted Begonia. One soul skill could heal someone completely. Why would she learn those other things?
Lin Yang sighed softly. People were inherently lazy. The existence of martial souls had raised the upper limit of this world in every aspect, but it had also created dependence.
Even terminal illnesses could eventually be cured under martial soul treatment if given enough time. In ordinary people's eyes, if even soul masters couldn't do something, then naturally they couldn't either. This had already become a consensus among everyone.
Lin Yang withdrew his thoughts and spoke calmly, "It's fine. If you're willing, you can start learning from the basics in the Butterfly House."
Ye Lingling showed almost no hesitation and nodded. "I'm willing!"
Lin Yang didn't say much more. He introduced her to the other girls working in the Butterfly House one by one and showed her around the entire layout.
Finally, the three of them stopped in front of Lin Yang's laboratory door. This was the largest room in the Butterfly House and its core.
Pushing open the door, the entire room was divided into two areas.
One side was a regular laboratory with various beakers, test tubes, and bottles containing solutions of different colors. It looked no different from an ordinary alchemy workshop.
The other side, however, presented a completely different scene. There stood a huge sealed container, entirely made of metal, with a smooth surface that showed nothing special. Only by getting closer could one notice several hatch-like entrances around the container.
Besides Lin Yang, no one knew what this container was for.
In reality, this mysterious-looking container was only a shell. If it were cut open, the sight inside would make anyone's scalp tingle. Inside was a honeycomb-like support structure formed by densely interwoven flesh and bones. One could even clearly see the vascular network beneath the flesh pulsing slightly.
In addition, there were many small tentacles inside the container, flexibly moving through every corner. These were Lin Yang's own flesh—living flesh!
For convenience, Lin Yang had used his own flesh to create this reaction furnace. He had even differentiated a secondary brain inside it. This brain had no independent consciousness. Without Lin Yang's control, it could only perform the most basic operations.
However, with this secondary brain, even if Lin Yang himself was not in the Butterfly House, the flesh reaction furnace could still perform minimal potion synthesis according to the programs he had preset. This freed Lin Yang from the work.
But as the saying goes, only the family knows its own affairs. This thing was useful, but it was simply too horrifying. It was practically Douluo-style Cthulhu. Therefore, Lin Yang never introduced it in detail.
After the tour of the Butterfly House, Ye Lingling officially joined. Like Lin Yang, she only needed to come to the Butterfly House in the evening for one or two hours each day to help Catherine with miscellaneous tasks. When Lin Yang taught Catherine, she could listen as well. Occasionally, when she didn't understand something, she would ask for guidance afterward.
In special classes, to make things more intuitive, they needed teaching aids—our "general teacher." This "general teacher," which already had some "teaching experience," had long been dissected by Catherine into pieces. Muscles, bones, blood vessels, nerves, etc., were displayed in categories, like an artwork that had been dismantled and carefully arranged.
But not everyone could accept this kind of "artwork."
When Catherine, as usual, calmly brought out the "general teacher," Ye Lingling's expression underwent a dramatic change for the first time. Her eternally calm face first froze, then the color drained away bit by bit. Her eyes widened, pupils contracting. Shock, disgust, and horror alternated repeatedly on her face.
Finally, they converged into an unstoppable wave of nausea. Under the gaze of Lin Yang and Catherine, she turned and ran. She rushed to a corner of the courtyard, leaned against the wall, and vomited.
Lin Yang stood at the doorway, seeing this scene, and the corner of his mouth twitched. "…I forgot to tell her about this."
Catherine poked her head out from inside the room with an innocent face. "Teacher, did I scare Sister Lingling?"
"It's fine," Lin Yang waved his hand. "Everyone is like this the first time. You get used to it after vomiting a few times."
As soon as he finished speaking, an even louder retching sound came from the corner.
Lin Yang and Catherine exchanged a glance, shrugged, and didn't dare speak again.
