Looking at the effects presented by the potion in front of him, Kevin naturally intended to brew it.
This was almost the most balanced effect possible after the fusion of these materials, and it met his expected standards.
The effects presented previously had been much more ambiguous; the key to judging whether a potion's effect is powerful lies in how clearly it is described.
Although the description of this effect still seemed abstract and vague, it was already quite clear compared to the expressions of other potions of this type.
Regardless, once the potion is brewed, taking a sip to experience it will reveal whether it is powerful or not.
If it doesn't meet his requirements, he can simply record it as a preparation method, which also counts as experience.
In fact, such instances of waste are quite common.
The potions Kevin has brewed during this period have had many strange effects, and many of them have been useless.
For example, potions that make you fart continuously, cause skin redness, or result in harmless allergic symptoms—all sorts of strange and useless potions.
He just records them as experience.
Kevin adjusted his state, closed his eyes, took a deep breath, and then placed both hands on the base of the Pharmaceutical Table.
His body instantly entered the state of "Zetsu," and Nen poured continuously into the Pharmaceutical Table.
The Pharmaceutical Table began to spin rapidly, and the time required for production continued to increase.
Sweat trickled down Kevin's face, something he hadn't experienced in a long time.
He hadn't encountered this situation while brewing potions for a long time; it only happened back when his potential Nen Volume was insufficient.
The production process lasted for about forty minutes before Kevin felt the speed at which the Pharmaceutical Table absorbed Nen gradually slow down until it stopped.
The Pharmaceutical Table stopped, the materials on the tray had completely disappeared, and a test tube appeared in the hole of the base.
Kevin pulled out the test tube. The liquid inside had distinct colors, with egg-white and pitch-black hues blending together in a Spiral.
"B-rank, it is undoubtedly B-rank."
Kevin made his judgment based on the Nen Volume he had consumed.
According to Kevin's criteria, potions requiring less than 10,000 Nen Volume to brew are classified as C-rank.
potions requiring between 10,000 and 100,000 Nen Volume, he considers to be B-rank.
After training during this period, his potential Nen Volume was approximately 23,000 to 24,000.
This time, he had consumed about half of the energy in his body, meaning this potion had cost him over 10,000 Nen Volume, just reaching the minimum standard for B-rank.
Therefore, this was undoubtedly a B-rank potion.
"What exactly will this potion do?" Kevin couldn't help but ponder.
He had previously brewed a potion using similar materials.
However, last time he used the molted horn of a Double-Headed Wolf, which was just a residual empty shell, and the Golden-Bottom Petals used were of the most common variety, not the higher-quality Golden-Veined Petals he used today.
The auxiliary materials were also common ones he had purchased, and they were stone materials, which inherently had compatibility issues.
Although he didn't consume the potion he made last time, he witnessed the effect of the Essence Sensing Potion.
Even in such an angry situation, Mito remained calm, controlling his emotions to the extreme.
From his fiery red eyes, one could see that anger still existed, but his emotions were firmly controlled, presenting a very peculiar state.
From this, Kevin inferred that the potion in his hand was also highly likely to be closely related to emotions and willpower.
However, to know the exact effect, he would have to consume it himself.
There was no need to be too frugal this time.
After all, both the Double-Headed Wolf horn and the petals in his hand were in sufficient supply.
The wolf horn was as big as a palm and solid; once ground into powder, it could be divided into many portions.
The next day.
Early in the morning, Kevin arrived at the training ground.
At this time, Pairo and Kurapika had actually arrived earlier than him and were already training independently on the training ground.
"Damn it, Pairo! Stop messing with what I see." Kurapika complained loudly while running.
Because as he ran, he would suddenly flicker for no reason, or make a sharp turn and circle around, or even be startled into stopping abruptly, while Pairo was following him with his eyes closed, running crookedly while laughing.
He was also trying to move with his eyes closed.
"I am training you. Since I possess the ability to construct hallucinations, there is no guarantee that others won't."
"Moreover, my hallucinations are only visual; they merely cause your eyes to have illusions. You cannot rely solely on your eyes to observe."
Pairo was exercising his body while also training his Nen Ability.
His Nen Ability was extremely easy to break; it could be broken with "En" almost instantly.
Therefore, he had to resolve the battle the moment he first altered the enemy's hallucinations, before they were detected. Thus, he had to make his modifications precise enough, subtle and silent.
Of course, this made things difficult for Kurapika, who had to endure the interference while persisting in his physical training; it could be considered a unique way of training.
"Uncle Kevin!" Kurapika waved to greet Kevin when he saw him.
Pairo also opened his eyes and waved.
Kevin smiled and waved back, signaling them to continue, then walked to the center of the training ground, closed his eyes, and meditated silently.
This was a deep learning method he had explored for himself.
By first performing a meditation to clear his mind of distractions, he could effectively enhance his perception of the potion's effects afterward.
To some extent, this was strengthening his sensory abilities and reinforcing his subconscious judgment.
Put simply, it was strengthening his intuition.
This was a realization he had gained from long-term practical use of potions.
As the meditation deepened, the "Ten" on his body, without conscious control, tightly wrapped around him, forming an object like an eggshell that was airtight and motionless.
This meditation lasted for half an hour.
By this time, Pairo and Kurapika were already sitting in the rest area, drinking water quietly and observing Kevin's state.
"He has reached a realm we cannot understand."
Kurapika muttered to himself.
Pairo nodded in agreement from the side.
Suddenly, Kevin opened his eyes. A syringe appeared in his hand; he inserted the potion into the syringe and then injected it directly into his thigh.
The effect of the potion spread throughout his body instantly.
With the reinforcing effect of the syringe, this perception became very obvious.
After meditating and maintaining a state of clear willpower and sharp intuition, this perception became even stronger.
He could feel the power of the potion instantly spread throughout his entire body, permeating every corner.
Subsequently, most of the power converged and surged into his brain.
This indicated that this potion primarily acted on the brain.
Under this perception, Kevin closed his eyes again.
It was pitch black before his eyes, but it seemed somewhat unusual.
With the help of the potion's power, he sensed light spots in the distance; those were the sources of other people's emotions and willpower.
Undoubtedly, they were Pairo and Kurapika, and Kevin had not used "En" to scan.
He could even judge Pairo and Kurapika's emotions of good and evil through this perception.
These emotions of good and evil were not what they were projecting toward others, but rather those directed at Kevin.
The obvious goodwill made the two stand out particularly in Kevin's emotional perception after closing his eyes.
Kevin also sensed the situation further away.
However, the further the distance, the more blurred the perception; he could only detect another light spot radiating goodwill approaching them.
At this time... is it Rosanna?
As the light spot got closer and closer, the door was pushed open, and indeed, Rosanna walked in.
She saw the situation on the training ground and saw her son make a hush gesture from afar.
Rosanna nodded in understanding and tiptoed over to sit beside the two.
This sensing distance was no longer short, and unlike "En," it did not use Nen to scan.
In other words, enemies could not detect this "scanning"-like behavior, allowing him to discover their location without alerting them.
Especially when an enemy harbors malice toward him, this willpower perception does not shift according to the enemy's subjective thoughts.
Even if the enemy is just observing simply, without any other actions, they will radiate emotions of good or evil.
This was very good.
Kevin's intuition was getting stronger with training, but intuition is just intuition; he couldn't know the specific location of enemies without using "En."
And once he used "En," it was equivalent to telling the enemy that he had discovered them.
This would alert the enemy, bring things out into the open, and cause him to miss the advantage of shifting from the enemy being in the dark and him in the light, to the enemy being in the light and him in the dark.
"But the sensing distance is still not far enough."
Kevin thought to himself.
Suddenly, he seemed to have thought of something and readjusted his "En," letting it spread outward like a normal "En."
Under normal circumstances, his "En" would stop after extending 20 meters outward.
But through this 20-meter extension, his range of will perception instantly expanded countless times, forming a massive sphere of will perception that directly enveloped the manor buildings in the distance.
Within this range, everyone was radiating goodwill toward him; this was merely a manifestation of his own perception of good and evil.
Those emotional perception signals from unknown identities moved about within Kevin's perception.
Kevin retracted his perception and opened his eyes.
He felt that the function of this potion should not stop there; there must be other effects.
Because he did not feel that this potion had any control over his own emotions—in other words, it did not possess the ability to control one's own emotions like the 『Essence Sensing Potion』.
However, that emotional reconnaissance function just now did indeed exist.
He had once seen Mito use a potion with similar effects, which was the reason why Mito was still able to fight enemies accurately after gouging out his eyes while the potion was still in effect.
Recalling the description of the potion: 『Nen will provide feedback on and change the good and evil will of others and oneself.』
How should this sentence be understood?
Kevin looked toward the rest area and waved.
Kurapika and Pairo both pointed at themselves, asking if he was calling them, and Kevin nodded.
The two walked over.
"Uncle, is there something you need?" Pairo asked with confusion.
Kevin nodded and said, "I need the two of you to be test subjects for once and help me test my new ability."
Although the two were a bit confused, they still nodded.
Kevin extended his Nen toward the two of them.
His Nen received feedback.
"Hmm?"
Kevin couldn't help but exclaim in surprise. So this is the kind of feedback it gives?
This type of feedback was very peculiar, but combined with the legend of the Double-Headed Wolf, it was understandable why such strange feedback would appear.
Simply put, after Kevin's Nen surged into their bodies, the feedback he received was actually their sense of good and evil.
In layman's terms, Kevin could gain insight into the other party's values through this method.
The closer the other party's values were to his own, the more obvious the feedback, and his Nen would become gentler. The opposite was also true.
Could this be the ability used by the Double-Headed Wolf to distinguish whether a human is benevolent?
From the feedback, it was clear that Pairo's values were similar to Kevin's, while Kurapika's values were even more "upright" than Kevin's.
You have to realize, these values were reshaped after they experienced the genocide of their clan.
Pairo being similar to him meant that he was once even kinder than himself, while Kurapika was now even kinder and had stronger moral boundaries than himself.
Truly worthy of being youths living in seclusion, untouched by the pollution of the world.
Although Kevin didn't consider himself a great person, he believed he lived up to his parents' teachings and did not fail the guidance of society and his teachers.
With this ability, he could judge whether the two were heading toward extremes.
"Not bad at all," Kevin thought. "Although this ability is a bit strange, having more skills is never a burden, and this is essentially a functional ability that doesn't require extra energy to train or strengthen."
Having understood the feedback of others' good and evil, how should his own good and evil feedback be manifested?
Kevin clenched his fist, infused it with Nen, and then looked at the two people in front of him.
This look made the two subconsciously take half a step back.
"Stand still and let me punch you."
The two pursed their lips and widened their eyes.
Although they knew Kevin wouldn't actually hit them hard, they still couldn't help but feel a little nervous.
But Kevin wouldn't give them time to react.
Suddenly.
His fist flashed.
Before they could react, it had already landed on their stomachs.
"Ugh—hm?"
After taking the punch, the two instinctively shuddered, then scratched their heads in confusion.
"I don't feel anything?" Kurapika was puzzled.
He could feel that Kevin had used a certain amount of strength in that punch, but there was no pain from being struck.
"Huh? My… my stamina has recovered, just as if I hadn't just been training." Pairo said in surprise.
Hearing this, Kurapika quickly checked himself and realized he had the same change.
At this moment, Kevin clenched his fist, realization dawning on him: So that's it.
The punch he had just thrown carried no malice whatsoever and was purely out of goodwill.
His Nen responded to this goodwill, enveloping the Nen and striking into the other party's body, restoring their stamina.
After throwing this punch, Kevin understood the effect it could bring.
Although this punch couldn't be called a "Healer Punch," it could definitely be called a "Mana Punch."
Based on his goodwill, the Nen would provide corresponding feedback, and after entering the other party's body, it could restore their stamina and even alleviate their mental fatigue.
"What kind of ability is this?" Kurapika asked curiously.
Kevin didn't explain much and threw another punch.
This time, Kurapika took the punch squarely, but only stepped back a few paces and still felt no pain.
"See if you can feel any changes?"
Kurapika nodded, hopped in place a couple of times, and swung his fist.
"Hmm… my punches feel more powerful?" he said uncertainly.
Pairo simply walked up to him and let him punch him.
The two often sparred, so Kurapika threw a punch straight at him.
"It's heavier than before." Pairo judged.
Alright, now it was confirmed.
Kevin thus determined how this ability of his functioned.
Essentially, this is an Enhancer ability. A punch carrying goodwill allows his Nen to incorporate an enhancement trait and integrate into the other party's body, strengthening a certain aspect of them.
This enhancement is based on Kevin's own judgment, and one punch can only provide one type of enhancement.
The degree of enhancement won't be overly exaggerated, but rather referenced against Kevin's own standards.
Enhancer Nen, even without utilizing a specific Nen Ability, will strengthen all aspects of the body.
Otherwise, the Enhancer category wouldn't be called the category with the strongest offensive capabilities.
This punch carrying goodwill could well be called an "Enhancement Punch."
"Pretty interesting." Kevin smiled, looking at his fist with greatly increased interest.
Although the enhancement effect is not very obvious at the moment, and using his Nen to enhance a new Nen User like Kurapika is extremely limited, it is very interesting.
And it can be foreseen that as his strength increases, the enhancement effect will also get better and better.
Especially when there is a larger gap in strength between the two sides, the effect might be more significant.
"What if I throw a punch with malice? Could it be that based on the characteristics of the Enhancer category, adding malice would make the attack more destructive?" Kevin thought.
Inferring from the opposite of the "Enhancement Punch," it should be like this.
If it carries malice, perhaps it could enhance the piercing power, destructive power, or impact of this punch?
Kevin walked to the other side where the sandbags were placed.
He threw a punch at the sandbag with malice.
Although he couldn't completely control his emotions, he could consciously instill goodwill or malice.
"Bang!"
With one punch, a piercing hole was punched into the center of the sandbag, and sand flowed out from the hole.
The sandbag didn't explode entirely; this punch enhanced piercing, and the fist carrying malice increased the piercing capability.
"Impressive." Kevin couldn't help but exclaim.
The description of this potion seems abstract, but its actual effect is very unique.
There is somewhat of a possibility that it varies from person to person.
Essentially, it uses the will of good and evil to envelop one's Nen, thereby achieving various effects.
Most importantly, this ability fits him very well, and he doesn't need to be distracted by extra training or study.
As his strength continues to increase, the effects he can achieve will become better and better, whether it's the "Goodwill Punch" to enhance others or the "Malice Punch" to attack others.
Moreover... Kevin looked ahead, charged his arm, and Nen exploded. The Nen formed dense hexagons in front of his fist, and the malice enhanced the impact of this punch.
"Ha!"
He shouted.
"Boom!"
With an air explosion, the air was visibly compressed into a circle and then spread out. The sandbag was directly knocked away and exploded in mid-air.
Sand fell like raindrops.
Behind Kevin, Kurapika and Pairo stood in place, mouths wide open, staring blankly at this scene.
