Hunter x Hunter: Infinite Growth.

Kevin has discovered that the way to identify unorthodox methods is to check if the other person's Nen skills are solid.

Nen users who have received instruction don't seem to be in a hurry to develop their Nen abilities. Instead, they wait until they have thoroughly mastered the basic techniques before considering it.

"Okay, fine. When I reach the 200th floor, I'll fight you first. Are you going to develop your own Nen ability? If you don't, you might not be able to beat me."

To everyone's surprise, Kate shook her head: "No, I plan to pass my teacher's test and become his disciple before I think about these things."

"Really?" Kevin asked with some regret, then added, "So you're planning to leave?"

The last fight he watched a few days ago was Kate's last one. Kate had almost reached her limit, and all she needed was time to train and turn her gains into strength.

Continuing to participate in battles above the 200th floor is not very meaningful.

“Hmm.” Kate nodded.

"I will continue to work hard, pass the teacher's test, and prepare for the next Hunter Exam, which will be held in January next year."

This piqued Kevin's interest, and he leaned closer to ask, "The Hunter Exam? You've taken it before?"

Kate nodded: "I participated in the exam earlier this year. At the end of the exam, I encountered another Nen user who was also a candidate. At that time, I was not good at fighting between Nen abilities, so I lost."

"Oh, I see." Kevin now understood why the other party had come here; he had been participating in battles above the 200th floor.

"Shall we go together then? To be honest, I'm quite interested in hunters, and I'll be ready by then too."

"Of course, we can do it together." It would be great to have a companion to take the exam with.

Kevin stood up, smiled, and patted the other person on the back: "Then you'd better do your best, or you'll fail again like before when you meet me."

"Heh, just you wait and see. I'll beat you to a pulp." Kate retorted defiantly.

"Haha, then I'll wait and see."

"Ha ha ha ha."

The two people, who were the same age, looked at each other and laughed.

Chapter Twenty-Two: Use of Potions X

Not far from Sky Arena, at Kevin's home.

In the basement, which had been converted into a warehouse and a pharmaceutical processing room, Kevin was conducting his daily routine of research.

"Isn't this too much?" Kevin asked, looking at the information displayed on the base of the pharmaceutical workbench.

Corrosive

This is clearly a poison.

At this moment, different items are placed on the three scale pans.

On the silver scale was a piece of special protein mineral the size of a thumb. This was an extremely expensive medicinal mineral, and this small piece cost Kevin one million.

If the items on the silver scale are so expensive, then the items on the gold scale must be even more valuable.

The shed horn that the two-headed wolf gave Kevin on the day he first transmigrated here is on the table.

This is a rare item with a market value of up to 50 million, and its quantity is extremely limited, with the price increasing year by year.

Most importantly, Kevin only has this one shed horn.

Now he fully understands why he felt a faint longing when he held that shed horn in his hand.

It turns out that he desires certain powerful and extremely precious pharmaceutical materials, and the more precious and powerful the materials are, the stronger this desire becomes.

However, it's not only expensive materials that evoke this feeling. Take the opal in front of him, for example; it's worth a million dollars, and Kevin felt a surge of desire when he touched it.

Kevin also has a precious material that he acquired at an online auction for over six million dollars, which was recently delivered to him by private jet.

But strangely, this material did not arouse any desire in him.

Currently, the materials displayed on the gold and silver scales are the only two things that can arouse his desire.

The copper plate contained a fusion agent. Based on his knowledge and recent studies, Kevin had experimented with several fusion agents capable of fusing the properties of these two materials.

However, there is a problem: no fusion agent can achieve the desired effect.

The base indicates that the best-performing result so far is: [Subtle detection of malice].

At first glance, this effect seems miraculous. But for Kevin now, even without the drug, he can react to targets with malicious intent.

Of course, the specific level of detail is unknown.

The reason why the horns on the two-headed wolf's head are so expensive is because of this legend.

Two-headed wolves have always been a rare species, struggling to reproduce. Over the long course of their evolution, they have learned to distinguish emotions and differentiate between good and evil.

The source of this ability is said to be the horns on their heads.

People believe that medicine made from their heads and horns can alleviate mental health problems. It is indeed effective, which is why it remains expensive.

This is also why the two-headed wolf is on the verge of extinction.

The special opal that Kevin felt a slight longing for also possessed the effect of sharpening the mind and agile thinking. The two materials were compatible in nature, but they were missing a suitable fusion agent.

Another failure led Kevin to cross out the effects of the new material in his notebook.

"There aren't many suitable fusion agents left to think of..." Kevin muttered to himself, looking at the notes in his notebook.

He shook his head helplessly: "Forget it, let's continue the experiment tomorrow. Let's first turn the new materials that arrived today into a potion."

Kevin processed the materials that had been airlifted in that day and then began making the medicine.

Based roughly on his memory, previous research records, and the research results of the past few months, Kevin categorized the drugs he had created.

Grade D medicine: Made from ordinary materials, it works similarly to medicines sold in ordinary pharmacies, but with better efficacy and faster results; treatment can be completed within the duration of one dose.

It can treat common ailments like fever, colds, flu, and various allergies. There are many such formulas, most of which are recorded in the original owner's experimental logs.

Grade C drugs: Made from relatively expensive and difficult-to-obtain materials. Their effects are equivalent to high-end medications, or even a surgical procedure, and they are no longer limited to simple therapeutic effects. This grade of drug is what Kevin currently keeps on hand.

Two of them were made by the original owner, two were made by Kevin after the original owner only left behind a possible formula due to insufficient strength, and the other was made by Kevin through independent research in the past few months.

Truth serum: As the name suggests, it is used by those with weak willpower; after taking it, they will answer any question asked.

[Bone-setting agents: As the name suggests, after the fracture site is immobilized, one dose of this medication can heal most fractures within its duration.]

The original owner mainly made money through these two types of potions.

[Strength Potion: Increases muscle strength and visible energy, but accelerates the depletion of stamina and energy.]

[Healing Potion: Accelerates the healing of internal and external wounds, but consumes stamina and energy.]

These two medications were developed based on formulas recorded in experimental records, combined with memories in the mind, and after certain adjustments. They can be seen as the result of the joint efforts of the present Kevin and his past self.

Digestive aids: These continuously consume gas, accelerating the breakdown and digestion of food, and accumulating energy and nutrients.

This is a drug that Kevin developed himself. It has a very significant effect and is mainly used to accelerate the effects of physical exercise.

The specific method is to first eat a large meal until you are stuffed or even vomit, choosing high-calorie, high-nutrient "carb bomb" foods.

Then, within fifteen minutes of drinking the potion, the food will be rapidly digested. Afterward, high-intensity exercise will be performed to allow this energy to be released back into the body.

However, this method of taking and using medication can put a certain burden on the body and should not be used frequently.

After careful consideration, Kevin concluded that using it once every 8 to 10 days is reasonable. Of course, the interval between uses can be shortened depending on individual physical conditions.

For example, initially Kevin needed to wait 15 days before he could use it again, but now he can continue after about 10 days.

Thanks to this potion, Kevin's physical abilities improved dramatically in just three months. However, a large sum of money was also spent on the materials to make the potion, and now he has to continue making the potion.

Soon, using materials worth millions, a potion with a pale green color and slightly cloudy liquid was completed.

"This time it took 40 minutes and consumed about 40% of my energy, which is an improvement over before." Kevin was very satisfied with this. This was also a new function he discovered for the potion-making station: by making the same potion, he could judge his own growth based on the time taken and the energy consumed.

Kevin opened the box next to him, which was filled with packaged energy bars.

"Phew, don't taste it, just take a bite and swallow it," Kevin told himself.

To fully utilize the potion's effects, one must consume food with high energy density. Aside from high-grade monster meat, these specially made energy bars are the only other option. As for the taste, it's best described as "indescribable."

"I'll eat! I'll eat! I... ugh... keep eating!"

Kevin devoured a box of energy bars in a whirlwind, his face turning red from the effort.

"This is the necessary hardship for taking shortcuts, so persevere!"

Kevin swallowed the prepared medicine in one gulp.

Instantly, his energy erupted, surging and churning. This energy began to dissipate automatically, accelerating and enhancing his body's digestive abilities. Kevin's entire body began to turn red and hot.

"Is this essentially a kind of enhancement-type Nen ability?" Kevin couldn't help but ponder.

The effects of the drug are, in a sense, similar to using enhancement-type Nen to strengthen the body's digestive functions and organs.

Following this line of thought, if someone who is not a enhancement type uses this potion, the effect probably won't be as good as it is for them.

It's not entirely certain; he hasn't given the medicine to anyone else yet.

Fifteen minutes passed quickly. Kevin let out a long breath, his body temperature began to drop, and his complexion gradually returned to normal.

But at that moment, his stomach started growling.

"coming!"

Kevin was standing right next to the toilet when he rushed in without hesitation.
