As everyone left one by one, Kevin's life returned to an orderly state.
Drawing from ideas that sprouted during his collaboration with Cheadle and combining them with the various knowledge he had acquired, he set out to create new potions.
Kevin already had many concepts in mind, but turning these ideas into actual potions required time to carefully formulate the right herbs and dosages before they could be produced.
This was a gradual process; it could not be rushed.
Furthermore, this process allowed Kevin to understand every ingredient, gaining a deeper knowledge of their properties, so that he could produce the desired potions more quickly in the future.
In addition to this, Kevin maintained his habit of eating large amounts of food, then using potions to assist his training and promote his own growth.
The facts proved that this path of growth was feasible.
When Cheadle came over, Kevin specifically asked her to perform a comprehensive physical examination on him.
After all, he had been relying on the 『Digestion Potion』 to rapidly digest and absorb energy, which in turn allowed him to train frantically.
In terms of pure physical fitness, his growth rate was extremely fast.
Although he hadn't discovered any aftereffects during his previous self-examinations, if there were any oversight, the consequences would be unimaginable.
Moreover, he had been training this way for over half a year; even if problems were deeply hidden, they should have manifested by now.
Fortunately, after Cheadle's meticulous examination, the conclusion was that no hidden issues were found.
Kevin's physical condition was incredibly healthy.
This meant that as long as his body could handle it and he didn't force excessive use of the "potion," this training method was harmless.
At this stage, Kevin's physical condition allowed him to conduct this type of training every two days.
However, as time went on, the effectiveness of this training method gradually diminished.
First, the energy that food could provide was limited; even if Kevin only consumed high-calorie foods, there was an upper limit to his intake.
He couldn't actually eat until his stomach burst, and even when using the Digestion Potion, no matter how fast he ate, there was a limit.
These energies were digested and stored for frantic training, but there was also a limit to training intensity.
Because Kevin was training his physical body, not his Nen Ability, the energy provided by the 『Digestion Potion』 was only digested by his body, not by his Nen Ability.
Even if Kevin trained without stopping, he could not break through this limit.
Although his physical strength hadn't reached a perfect state, it seemed to be gradually approaching a limit, falling into a bottleneck.
It was a pure physical bottleneck.
Regarding this situation, Biscuit, who had considerable experience in training, pointed out the underlying reason.
This made Kevin recall his conversation with Biscuit a few days ago.
"The human body is not an existence capable of infinite growth; otherwise, humans would no longer be human. Training can indeed improve one's physique, but there is inevitably a limit."
"Moreover, although humans possess powerful adaptability, this adaptive change occurs on a timescale of thousands or tens of thousands of years."
"Although you have frantically enhanced your physique with the help of potions without side effects, the inherent limits of the human body are not easily broken."
In this world, people's physical fitness was much stronger than in the world Kevin lived in during his previous life, and they also possessed a special ability called Nen.
This greatly strengthened their upper limits.
But in essence, they were still human, not monsters.
From Biscuit's perspective, Kevin's current physical fitness was already approaching a certain limit.
Regarding pure physical strength, Biscuit was quite confident in her judgment.
From then on, even if he continued to train, or even used potions, his growth rate would gradually slow down until every step forward became exceptionally difficult.
Eventually, he would reach a state of limit where no matter how he trained, his physical fitness could not improve.
This was the human body, the limit of the vessel itself.
At the time, Kevin asked: "In other words, is this limit impossible to break? Has anyone ever reached such a boundary?"
As soon as the words left his mouth, Kevin felt he had asked a stupid question; after all, if no one had reached it, where would such experiential knowledge come from?
At that time, Biscuit just gazed at Kevin quietly, then pointed a finger at herself.
To be honest, it wasn't that Kevin didn't trust Biscuit.
It was just that in his cognition, the results of physical training must be reflected in one's appearance.
A strong and resilient body usually displays perfect muscle lines and a burly physique.
Although Nen Abilities existed in this world, it had not escaped basic physical rules.
Therefore, given Biscuit's current appearance and figure like a little girl, it was truly hard for Kevin to believe that she had reached her physical limit.
Although Biscuit's proportions were perfect and there were traces of training, no matter how he looked at it, she didn't look like someone who had reached the limit.
Perhaps she had only reached the limit that could be presented in the form of a little girl.
It was more likely that she used her own Nen Ability to disguise herself.
If that were the case, Biscuit's original appearance... he shouldn't think about it, he shouldn't think about it.
Facing Kevin's suspicion and confusion, Biscuit clearly had no intention of explaining, and even forbade Kevin from continuing to ask.
Wing was also present at the time and maintained absolute silence on the matter.
However, Kevin didn't care too much; he was more concerned about another question.
Regarding this question, Biscuit gave an answer: "Relying solely on one's own training, this limit is indeed difficult to break. But this world is vast and boundless; relying only on one's own strength is certainly not enough, but if one utilizes external forces, it is possible to break through."
"Take your potions for example; if you can obtain the top-tier materials, I believe you have the ability to create potions that break through limits."
Hearing this, Kevin nodded in deep agreement, but the problem was that he currently had no such materials at all.
Afterwards, Kevin seemed to understand something and silently glanced at Biscuit; the two shared a tacit understanding and stopped discussing this topic further.
As expected, a veteran like Biscuit could not possibly be unaware of the existence of the 『Dark Continent』.
Since Biscuit was so certain that the Dark Continent possessed materials to break through limits, could it be that the Hunter Association had relevant records?
Or had the Hunter Association actually been to the Dark Continent?
Regarding this, Kevin couldn't give an answer; after all, he knew very little about this aspect, only knowing a few fragments of information from Ging.
But regardless, Biscuit formulated a training plan for Kevin.
"Although you cannot further enhance your physical fitness with the help of potions and training, your physical fitness is already approaching the limit, which undoubtedly lays an extremely solid foundation for you."
Kevin indicated he understood these words.
"So now, you should shift your focus to other aspects, such as improving speed, agility, and flexibility. These cannot be achieved simply through physical fitness training."
"In addition, you need to dig deeper into your potential; your Nen Volume is severely mismatched with your physical fitness. With your current physical fitness, increasing your Nen Volume by several times or even tenfold would not be a problem."
"Nen Volume and physical fitness are closely linked; although they don't perfectly match, the two influence each other deeply."
Simply put, Kevin had built a vessel with his body that was approaching the human limit, but inside the vessel, the liquid called "Nen" only occupied a thin layer; he needed to fill it with more Nen.
Ultimately, the plan Biscuit gave Kevin was that at this stage, it was best to use potions for training every five days, or even once a week.
His physical fitness no longer needed excessive enhancement; the foundation was already solid. What needed to be done now was to let this body, which was approaching its limit, bloom with results in other areas.
Otherwise, no matter how impressive your physical fitness is, if your Nen Volume is insufficient, you won't be able to withstand it when someone lands a punch.
At most, you would just be more resistant to getting beaten up than others.
Currently, Kevin only had two potions that were effective for training.
The 『Digestion Potion』 could improve physical fitness through large amounts of eating and frantic training, but it was limited to that.
This potion had no effect on improving agility, flexibility, speed, or the Nen Volume within his body.
But without a doubt, this potion could bring about an incomprehensible rate of improvement in physical fitness.
When he officially opened for business, he would separate this potion, creating a standard version and an enhanced version.
His current knowledge of potions allowed him to do this.
The profiteer mindset in Kevin's mind began to activate.
The other one, 『Strength Potion』, when combined with high-intensity training during use, could slightly increase "Manifest" and "Potential Nen Volume."
Of course, such an improvement was limited to Kevin, because his 『Blank Meteor』 could achieve this.
In the nearly year and a half since Kevin transmigrated, he was able to recover his original strength and increase his Nen Volume to 21,000; this potion deserved much of the credit.
However, this was also built on the foundation of a strong body.
This was also why Kevithat n chose physical fitness training, even though he knew Nen Volume was more important.
Because the rate of improvement in physical fitness was too fast, so fast that its returns far exceeded everything else.
Moreover, he could use the 『Strength Potion』 to train during the cooldown period of the 『Digestion Potion』.
Alternating between the two actually did not conflict.
However, gradually, the improvement effect of this potion began to fall behind Kevin's expectations.
Marginal utility existed for the improvement of anything, and the 『Strength Potion』 was no exception.
After all, it was just a common C-Rank potion.
Although it could still slightly increase Kevin's Nen Volume, compared to the total amount he aimed to reach, this improvement had become negligible.
However, adhering to the principle of "there is no alternative, and even a mosquito is meat no matter how small," Kevin continued to use this potion for a long time.
It was just that the speed of his Nen Volume growth had indeed slowed down significantly.
Regarding this situation, Biscuit offered a rather interesting piece of advice.
"If you were not an Enhancer Nen User, I would definitely suggest you focus on training other aspects rather than blindly pursuing an increase in basic Nen Volume.
"But it just so happens that you are an Enhancer, and you are training towards the most extreme direction of enhancement.
"Then you only need to focus on increasing your Nen Volume. Thinking about how to release more Nen, and how to make the Nen gather more effectively—this is your key task right now."
This was Biscuit's view on the matter.
That is how Enhancer Nen Users are: simple and direct, constantly throwing punches, throwing hard punches, throwing super hard punches.
As long as the power of the punch is great enough and the Nen is abundant enough, many seemingly complex problems can be broken through with sheer force.
In the world of martial arts, nothing is unbreakable, except for speed.
Furthermore, Kevin possessed Nen control ability beyond the average person, as well as a Nen Ability that could fix the effects of potions.
In particular, the "Burst" and "Iron Wall" techniques, which were clearly derived from the potion effects, were perfectly adapted to Kevin's current Nen Ability combat style.
With an Iron Wall punch unleashed beyond one's limits, just go ahead and hit; every hit lands without a whimper.
Obviously, Kevin had thought deeply about this aspect and had a clear plan for his goals.
Precisely because of this, Biscuit was very reassured about Kevin's self-training, firmly believing that he would definitely grow to a height that others could hardly reach.
And Kevin also roughly understood the advice Biscuit had provided.
The low-level potion cheat had reached its limit; before the higher-level potion cheat arrived, he would just honestly train in the traditional way during this interim period.
Although the speed of improvement was not as exaggerated as when using potions, it was not far off from Kevin's current ability.
At this moment, Kevin was thinking about these matters while planning his upcoming tasks.
This was a habit he had cultivated for a long time; whenever he completed a phase of tasks, he would list the items for the next phase, and then complete or prepare to complete them one by one.
And after Biscuit's analysis earlier, Kevin decided to initiate the three members of the Kurta Clan into Nen.
Secondly, he would build a shopping website and solve the logistics problem for goods.
Red Stone Pharmaceuticals—no, he didn't need to worry too much about this aspect. He had learned a little about it before, and the project had been steadily advancing.
Light was very attentive to his career, and coupled with some potions provided by Kevin, he was rapidly building a network of connections; he had extremely high talent in this area.
Especially now that Kevin was acting as his backing, he was full of confidence.
He also saw Kevin's "connections," those strange characters who looked powerful.
Then, there was the enhancement of 『 Moments Dream 』, as well as materializing additional tools.
He already had initial ideas for these two routes and was steadily advancing them.
Then there was the production of new potions. This could not be rushed; he already had ideas in his mind, and the relevant operations had been started.
Now that the materials were sufficient, it was natural to produce a batch of new potions to further strengthen his power.
Thinking of this, Kevin rubbed his head and got up to walk out of the room.
He instructed the servant nearby to notify the three of Kurapika to wait for him in the indoor training room.
Not long after, in an indoor training ground that had just been completed within the manor, the group gathered there.
Kevin looked at the three members of the Kurta Clan in front of him and said: "After thinking about it for this period of time, I have decided to initiate you into Nen."
Hearing this, Kurapika and Pairo became excited instantly; they had long been impatient.
Even Rosanna could not help but reveal an expression intertwined with curiosity and nervousness; after all, under Kevin's teaching and demonstrations, she was also full of curiosity about Nen Ability.
However, at this moment, Kevin's expression became serious, and he looked at Kurapika and Pairo with a serious gaze.
"You two, let's make a pact."
Upon hearing this, the two put away their excitement and nodded with serious expressions.
They didn't even ask what kind of pact it was.
"I will initiate you into Nen and teach you the relevant techniques in depth. However, the construction of your Nen Ability must take place after one year.
"During this one year, you can only perform basic Nen Ability training and meditation."
This was Biscuit's teaching experience, and Wing had said the same.
For geniuses, it is very necessary to build a good foundation before constructing their ability.
For those who are not as gifted, they can construct their Nen Ability once they are proficient in using the Four Major Principles.
As a Gem Hunter, Biscuit had always believed in "teaching students in accordance with their aptitude."
With only a few people in front of him, Kevin could also achieve this.
Kurapika and Pairo looked at each other, then turned their heads and nodded vigorously at Kevin.
Under Kevin's teaching during this period, they knew what it meant to proceed step by step and build a good foundation; even for revenge, one cannot be impatient or reckless.
Kevin smiled and extended his fist.
"Then it's a deal."
"Yeah!" The two responded in unison.
The three fists tapped together gently.
Beside them, Rosanna smiled, watching this scene with gratification.
"Then may I ask, do I also need to perform basic training and only construct my Nen Ability after a year?" Rosanna asked.
Hearing Rosanna's question, Kevin smiled and shook his head: "No, you don't need to."
Unlike Kurapika and Pairo, although Rosanna was a simple woman with little contact with the outside world, she was an adult after all, and both her psychological resilience and various conditions had met the requirements.
Moreover, judging from the training situation during this period, Rosanna's talent was clearly not comparable to Kurapika and Pairo.
Although she actively participated in combat training, the progress of her combat ability could only be described as average.
In terms of physical training, the results she achieved were not bad, but there was still a certain gap compared to Kurapika and Pairo.
But it didn't matter; the 『 Digestion Potion 』 would do the trick.
However, Rosanna learned knowledge extremely fast. She was already following Light to learn about management, and was even self-studying finance and knowledge in other fields.
Except for training, she spent most of her time around Light, learning from experience.
She was a clever woman who keenly sensed the team's needs and proactively filled this gap.
The reason she worked hard to Train and longed to learn Nen Ability was not for the purpose of revenge.
Although Kevin did not know the specific reason, he knew that the hatred in Rosanna's heart was far less intense than that of Kurapika and Pairo.
It was more out of a desire to protect; she understood that her son and Pairo, whom she treated as her foster son, would inevitably embark on a path of revenge.
She would not stop them, nor did she have the power to stop them.
But she did not want to become a burden to others as she had been in the past, becoming an object that needed to be protected.
She hoped that she could provide help and protection, rather than the opposite.
Therefore, for her, mastering Nen Ability was very necessary.
She would even go all out in this aspect, hoping that one day she could provide assistance to Kurapika and the others.
"Alright, I believe you are already clear about and familiar with how to control your own Nen.
"Now, I will awaken your Aura Nodes, and at that time, the Nen within your bodies will gush out uncontrollably.
"Follow the training method from before, control the Nen, wrap it around your body, and complete the most basic Nen initiation."
Hearing Kevin's words, the three nodded. They had long known this process by heart, but now it was time to put it into practice.
Kevin directly extended both hands.
Kurapika and Pairo placed their hands on Kevin's left hand, and Rosanna placed her hands on Kevin's right hand.
The three closed their eyes at the same time.
Kevin manipulated his own Nen, and relying on his excellent control ability over Nen, easily invaded the three people's bodies and instantly activated their Aura Nodes in the gentlest way.
The three's Nen erupted instantly. At this moment, they still kept their eyes closed, concentrating on meditation, and trying hard to control their Nen.
Kevin took a step back.
He had to admit that he seemed to have underestimated Kurapika and Pairo; the Nen erupted from both of them clearly exceeded the average standard.
He immediately began to guide them verbally.
Although the three already understood the whole process, Kevin's voice at this moment could strengthen their thinking and control, helping them better master their Nen.
Not long after, Kurapika and Pairo completed the "Ten" state.
Shortly after the two completed it, Rosanna also successfully reached this step.
This was not only due to their own talent but also inseparable from the effectiveness of the intensive training during this period.
In any case, the three perfectly reached the expected standard.
They even completed it more easily than Mito did at the time.
"You should have felt it by now, right? That thing wrapped around your body that you cannot see or touch."
The three nodded one after another, having genuinely felt this wondrous state.
"Then now, let's begin the teaching on the basics."
