The Nostrade Family estate.
Inside the infirmary.
With Cheadle's arrival, the infirmary had already been transformed into a top-tier hospital room.
Although a considerable amount of money was spent on this, for the Nostrade Family, these expenses were entirely within an acceptable range.
After all, treating illnesses and training people—who knows if someone in the family might need it in the future?
Especially his daughter.
Now, as long as it concerns his daughter, he will do his utmost.
At this moment, Pairo was not in the infirmary, as his physical condition had been thoroughly examined, and what needed to be done now was to create the appropriate potion.
Cheadle looked at the exquisitely packaged bottles and jars in front of her and nodded with satisfaction.
"These are the materials I could think of that you should be able to use your Nen Ability to create a targeted restorative potion with."
Looking at these drugs, there were some that even Kevin himself could not recognize.
Because many of them were products that had already undergone chemical extraction, fusion, and processing.
The medicinal effects of some of these plants could not even be found in records online or in books; these were all summarized by Cheadle based on her own experience.
Kevin was currently learning on the sly.
For his Nen Ability, the effects of every single material needed to be understood so that a suitable potion could be concocted.
"First, as we discussed earlier, given the potent effects of your potion, we need to create two different potions for the treatment. Although this treatment method is relatively radical, it will definitely be effective quickly and make him feel brand new."
The treatment method Cheadle mentioned was to first use one potion to thoroughly clear out the parts of Pairo's body that still had residual damage.
Because this part had already become deformed and was growing wildly, combined with the residual problems, it made treatment difficult. It was better to simply clear it all away.
Simply put, it was a special kind of poison.
This poison needed to be powerful yet gentle enough, and the standard for the poisoning must be precise and error-free. This had to be accurate down to the nerve level.
After clearing away the residual deformed ailments in his body, another special restorative potion would then be used for repair and regeneration.
『Healing Potion』 might have such an effect, but after Cheadle tried it herself, she stated it wouldn't work.
This potion was certainly useful, but the problem was that it was a comprehensive, rapid treatment. Compared to the current high-precision surgery and treatment operations, it seemed too crude.
Moreover, the potion itself was intended for treating sudden external and internal injuries, where the goal was rapid treatment to save a life. What was needed now was a targeted potion: in this way, Pairo's problem could be solved in a short time.
Of course, he would definitely have to suffer during the treatment process, but this was a price that had to be paid.
Regarding this, before the medicinal materials were even obtained, the two of them had communicated for a long time and finally reached this feasible conclusion.
After all, Cheadle was at the top level in the global medical field; she approved of this treatment method, and the entire treatment plan was mainly planned and designed by her.
This was a tailor-made plan after fully understanding Kevin's Nen Ability. Kevin mainly served as a tool.
"Now, let's try the formula I initially conceived."
Following Cheadle's ideas, the two began to process these medicinal materials.
"Velvet Poison, a poison extracted from the Velvet Poison Herb. It looks gentle but is fatal; it is a dissolving poison. The surface of this plant has tiny thorns that release poison upon piercing the skin, immediately dissolving the body's internal structures. However, if swallowed normally, it will not cause any problems."
Cheadle explained as she worked; some materials, without special channels, would certainly not be easy to acquire.
"Now, use this machine to extract the toxin and concentrate it. From this much medicinal material, we can probably extract about 200 grams."
As the machine ran, soon, about 200 grams of venom were extracted and stored.
Next, other medicinal materials were also subjected to various treatments. Some required keeping fresh, some needed to be dried for storage, and others were processed into powder.
"This is a Honey Poison Sac, which is the honey sac of a large insect, and a poisonous one at that. The specific composition of the substances inside depends mainly on the environment in which this insect lives."
"I have heard of cases where they turned into nutrient bags due to the environment. I think if you want to create some special potions in the future, you can keep an eye on this kind of insect."
"They are relatively easy to raise, they just need a large area of plant environment with the same attributes, which requires some effort to set up."
Cheadle provided advice to Kevin based on her own experience. At this moment, Kevin remained silent, nodding and recording seriously on the side. He thought to himself: "Sis, say more." He was learning on the sly with intensity.
After these few days of communication with Cheadle, Kevin felt that his knowledge in pharmacology had improved by leaps and bounds.
He couldn't wait to create more practical new potions, but he suppressed this excitement, telling himself that he still needed to continue learning.
Soon, the various processed materials were neatly arranged in front of them according to their categories.
Cheadle took out a small container containing a small piece of skin and flesh. This was taken from Pairo. This piece of human material would be used for the 『Fusion Agent』.
Kevin had never thought that such material could be used as a Fusion Agent, but Cheadle just had such bold ideas.
She even believed that if Kevin were to offer customized services in the future, such a Fusion Agent would be essential. Everyone's physical constitution is different; using flesh and blood as a Fusion Agent, or even as a part of the auxiliary materials, might make the potion more compatible with the user's body.
This was mainly considering the needs of customization; customization is often aimed at a specific aspect, and since people's constitutions differ, various problems can easily arise. Regarding the deep medical knowledge in this area, it still required continuous learning to gain a deep understanding.
Kevin took a deep breath and materialized the Pharmaceutical Table. He placed the appropriate materials on the Pharmaceutical Table and checked the description of the result provided by the Pharmaceutical Table.
『Biological Dissolution: Capable of dissolving necrotic parts hidden within a specific target's body, but will also cause dissolving damage to some non-necrotic targets.』
"This won't do." Seeing this description, Cheadle shook her head. This certainly wouldn't work. This was internal dissolution; if it accidentally dissolved important parts, it might cause Pairo to become paralyzed directly. With even worse luck, he might even die on the spot. Such a risk was too high; it was simply not something Kevin was willing to let Pairo endure.
The two readjusted the materials. At least the goal was correct, and the description already indicated that it could indeed internally dissolve necrotic parts; they now only needed to eliminate the problem of random damage. The materials themselves should be fine; the key lay in the dosage of the materials and whether the fusion method was correct.
After many adjustments, a perfect formula was finally obtained.
『Gold Scale: Velvet Poison (Extract - 15g)』 『Silver Scale: Honey Insect Poison Sac (Powdered - 115g)』 『Copper Scale: Biological Sample (Whole Piece - 3g)』 『Finished Product: Targeted at special biological individuals, dissolves deformed necrotic parts within their bodies; requires target guidance.』
This was exactly the finished product they wanted. Soon, the potion began to fuse and produce, and Kevin finished making it in just a few minutes.
"Next is the repair and growth part, which is relatively easier." Cheadle said with a sigh of relief.
This was indeed the case; the dissolution part had high risk, so the difficulty was high and required repeated adjustments. On the other hand, restorative treatment was relatively simple; even if there was an overflow of effects, it didn't matter, as long as the parts that needed repair could be successfully repaired.
Moreover, Kevin already had several potions with healing effects for different scenarios in his hands. He had sufficient experience in this area; after all, whenever he thought of potions, the first thing that came to mind was definitely the healing aspect. He had initially learned and developed in this direction.
Relying on Cheadle's understanding of drugs, it didn't take much time at all, and after consuming some relatively precious materials, a potion that somewhat exceeded their expectations was born. The effect clearly exceeded their estimates.
『Result: Consumes physical strength and nutrients to repair a living organism.』
"Repair? Isn't this description too general?" Cheadle asked, frowning in confusion. This statement was too vague; what did it mean to repair a living organism? What aspects of repair could it perform? And how should this kind of repair be defined?
After all, Cheadle was a top medical expert and also a top legal scholar; she could not accept such an ambiguous definition. She needed a precise and clear explanation. If they couldn't figure it out, this potion that had already been conceived would be abandoned, and the two of them would have to spend quite a lot of time rethinking and constructing it.
"You cannot completely view Nen Ability products using medical thinking, especially this Nen Ability of mine. The way it has usage conditions that lean towards realistic scientific principles makes you forget its essence." Kevin reminded her.
Hearing this, Cheadle realized and nodded: "You are right, I was thinking too scientifically and too meticulously just now."
She was not just a simple top medical expert; she was also a top Nen User. Things like Nen Abilities, more or less, all carry some difficult-to-understand fantastical colors. After all, it is a product jointly determined by a person's experiences, will, and body. It often conforms to some realistic scientific theorems, but in some aspects, it transcends common sense. For example, the classic Specialization系 and Conjuration.
Specialization系 often produces things that are completely impossible to explain with modern science; attempting to explain them is nothing short of whimsical.
The characteristics of Conjuration system are more obvious; items created through Conjuration often have extreme enhancements in a certain aspect, and may even bring about certain "rules."
Just like conjuring an ordinary rope; as long as the conditions are met, it will definitely be able to bind the target.
Even if the opponent's strength is far above one's own, they will be unable to break free.
"Then what do you think the 'repair' in your potion means?"
Regarding Cheadle's question, Kevin had actually been thinking about it from the very beginning.
"There are two possibilities. The first is also the most exaggerated possibility: comprehensive repair of the body, which can even be understood as limb regeneration."
"But this possibility is a bit unrealistic, though to some extent it does count as repair."
"However, a repair like limb regeneration looks more like recovering something lost."
Cheadle nodded: "So-called repair must surely involve damage, and there must be parts that can be repaired. I understand."
Kevin continued: "That's right. The second possibility is a situation where a certain part of the body is severed or damaged."
"For example, if an arm is severed, reattaching the arm is equivalent to finding the part for repair. Drinking the potion would allow the arm to be reattached."
"This should be considered more scientific and more in line with the original meaning of repair."
"From the perspective of modern science, wanting to perfectly reattach an arm is simply impossible; it would result in various problems and sequelae."
"But if it's a Nen Ability, there are many different abilities that could potentially achieve perfect repair. Do you think your potion can achieve this effect?"
Cheadle asked; this was the experience she had gained from working in this field.
A smile appeared on Kevin's face, and he said: "Whether it works is actually easy to judge. The materials we used this time are undoubtedly all C-grade."
Kevin felt a certain longing from these three materials, and the Fusion Agent used for the Healing Potion was the Gold-Bottom Petal.
It was those obtained previously.
Kevin had named the ordinary ones obtained previously 'Gold-Bottom Petals' because their base was golden.
Those of higher quality were called 'Gold-Vein Petals'.
"Now it depends on how long it takes me to make this potion, and how much Nen Volume it consumes."
His current Nen Volume had already reached 21,000. Even if it were the top-tier potion among C-grades, he would have the ability to create it.
Unless it was a B-grade potion, and it had to be a high-end one at that.
If it required that much Nen and time, then undoubtedly, this potion could achieve limb regeneration.
After speaking, he no longer hesitated and began the production directly.
Nen instantly poured into the Pharmaceutical Table.
Kevin sat in place and closed his eyes.
His Nen was being consumed continuously.
In the end, it actually took a full forty minutes. It had been a long time since Kevin had spent so long making a single potion.
This indicated that this potion had reached the top-tier level of C-grade.
"How is it?" Cheadle, who had been waiting on the side, asked.
Kevin took out the potion.
"It should be the second possibility we discussed."
Cheadle nodded; this was still within the scope of her understanding: "Then the demand for this potion must be huge."
She knew about Kevin's plan to set up a shop to sell potions.
Just thinking about it, one could tell that every client would definitely want to carry one on their person.
『This is a potion that can perform repairs when a limb is severed. Although there are many Nen Users with limb repair abilities, most of the time they might not be able to arrive in time or cannot be contacted.』
『This is a very logical and highly probable accidental situation.』
In such a situation, a big problem would arise.
If one had this potion on them at that time, wouldn't the problem be perfectly solved?
Regarding this kind of potion, Cheadle didn't have any special thoughts; after all, she had the ability to perform similar repair operations herself.
Kevin looked at the potion and nodded with satisfaction.
Finally, there was a high-quality potion that could be shown off.
This was truly an unexpected joy.
Now that both potions had been successfully made, it was time to perform the body repair for Pairo.
Everyone rushed over after learning the news.
Seeing so many people, Cheadle's face darkened: "Everyone out! When treatment is happening, family members should wait outside!"
Everyone silently retreated, and only Pairo was left in the hospital room.
At this moment, Pairo's youthful face revealed a hint of nervousness.
Cheadle showed a gentle smile and softly comforted him: "It's not as scary as you imagine. With the help of your uncle's potion, the treatment process will be very safe, and the results should be better than we expected, so you don't need to worry."
As she spoke, she gently patted Pairo's shoulder and led him to the hospital bed.
Afterwards, she relaxed and chatted about some things, soothing his emotions.
For someone who is both a lawyer and a doctor, the combination of the two made her skills in comforting people very powerful.
Pairo took a deep breath, trying to alleviate his inner nervousness.
Fortunately, under the training of practicing the control of the Scarlet Eyes, his ability to control his emotions was getting better and better.
He took off his clothes, leaving only a pair of specially made shorts.
After lying on the hospital bed, the medical equipment began to perform a detailed scan on his body.
Cheadle operated the instruments, and Kevin could see her infusing Nen into these devices.
After the anesthetic was injected, Pairo's eyes closed in less than two seconds.
Under Cheadle's operation, one needle was inserted into Pairo's lower limbs, and another was inserted into his eye socket.
The insertion points were all the lesion locations identified by the previous scan.
A subtle amount of Nen slowly flowed in.
Soon, a target was left at the site of the ailment.
This was the key to guiding the medication to the designated location for dissolution.
"Give him the medicine."
Kevin immediately acted, injecting the potion directly into Pairo's esophagus through a specially made syringe.
The potion was quickly absorbed.
"This potion is really strange; you can't actually see the process of it running and taking effect inside the body."
Cheadle still had the thought of observing the medication's effect.
After all, when the Nen Ability was generated, it used real existing materials, not purely Nen Ability. Logically, there should be a process of liquid evaporation; that should be the case.
As it turned out, there wasn't. It seems this potion can achieve a special effect of taking effect immediately after entering the body, skipping the process of taking effect.
Fifteen minutes after drinking it, that was the period during which the potion's effect was perfectly exerted.
It really fits the characteristics of a Nen Ability.
Guided by the target, the necrotic parts were instantly dissolved.
"If he weren't anesthetized, he would probably be screaming in pain by now," Cheadle muttered to herself.
After all, these parts aren't just necrotic; there are also parts that grew crooked or grew randomly. These are all parts of the body, and dissolving them is excruciatingly painful.
That feeling is truly like flesh being pierced; there's nothing one can do about it.
After a while, she continued: "Alright, it's time to use the Healing Potion."
Another potion entered Pairo's body through the syringe, and the repair effect immediately became apparent.
At this moment, Pairo had two wounds on his body.
One was a cut, and the other was the wound left from removing the flesh earlier.
Under the two's gaze, the cut gradually healed. It wasn't the process of blood scabbing and healing, but a process where the edges of the wound touched and disappeared.
But the wound from removing the flesh didn't change at all.
"It seems, just as you said, it's the second possibility," Cheadle concluded.
This phenomenon just further proved it.
The treatment was over.
Although Pairo was still in a coma, after a meticulous re-scan, it was discovered that Pairo had now recovered into a healthy child.
The problems with his eyes and legs had been solved, but the newly repaired parts still needed some time to recover.
As the anesthetic effect gradually wore off, Pairo sat up in a daze.
"I—I, hmm?"
He wanted to say something, but suddenly froze.
He reached out his hand and waved it in front of his eyes.
"My eyes."
Previously, as he grew older, his vision had become increasingly blurry, and seeing things was very exhausting. The symptoms were not quite the same as nearsightedness.
But now it was different.
Everything before his eyes was incredibly clear, as if the whole world had become clearer and brighter.
It felt like a monitor had been upgraded.
"I'm better? I'm really better?!" His voice was full of excitement.
Only he himself knew how painful and unbearable the process of slowly becoming disabled was.
Kevin rushed forward to help him up.
When
