Not far from the Sky Arena, at Kevin's home.
In the basement, which had been converted into a storage room and a pharmaceutical lab, Kevin was conducting his daily routine research.
"Is the amount too much?" Kevin looked at the display information on the base of the pharmaceutical table.
It's corrosive.
This was clearly a poison.
At this moment, three scales held different items.
On the silver scale was a thumb-sized piece of special protein mineral, an extremely expensive medicinal mineral. This small piece alone cost Kevin one million.
Since the item on the silver scale was so expensive, the one on the golden scale was even more valuable.
It held the shed horn that the Double-Headed Wolf had given Kevin on the day he transmigrated.
This was a rare item with a market value of up to fifty million, and its quantity was extremely scarce, with its price increasing year by year.
Most importantly, Kevin only had this one shed horn.
Now he completely understood why he had felt a faint longing when he first held this shed horn.
It turned out that some powerful and extremely precious pharmaceutical materials would make him feel longing. The more precious and powerful the material, the more obvious this longing would be.
However, it wasn't just expensive materials that triggered this emotion. For example, the protein stone in front of him, with a market value of one million, also caused a trace of longing in Kevin when he touched it.
Kevin also had a precious material that he had bought for over six million at an online auction and had it specially delivered to him by private jet a while ago.
But strangely, this material did not make him feel any longing.
Currently, the materials on the gold and silver scales were the only two things that could make him feel longing.
And on the copper plate was the fusion agent. Based on the knowledge in his mind and his recent studies, Kevin had tried many fusion agents that could combine the properties of these two materials.
However, the problem lay here: no fusion agent could achieve the effect he desired.
The display on the base showed that the best result currently was: "Slightly perceive malice."
At first glance, this effect seemed quite miraculous. But for Kevin now, even without taking the potion, he could react to targets with malicious intent.
Of course, the specific level of precision was unknown.
The horns on the Double-Headed Wolf's head were so expensive because of such a legend.
The Double-Headed Wolf species had always been scarce and difficult to breed. Over their long evolutionary history, they learned how to distinguish emotions and discern good from evil.
And the source of this ability, it was said, lay in the horns on their heads.
People believed that medicine made from their horns could alleviate mental problems. This thing was indeed effective, which was why the price remained high.
This was also why the Double-Headed Wolf was on the verge of extinction.
And the special opal that happened to make Kevin feel a trace of longing also had the effect of making the mind sharper and thoughts more agile. These two materials were compatible in nature; they just lacked a suitable fusion agent.
Another failure led Kevin to cross out the effect 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 records in his notebook.
He shook his head helplessly, "Forget it, I'll continue the experiment tomorrow. First, I'll make potions from the materials that arrived today."
Kevin processed the materials that had been air-freighted in today and then began making potions.
Kevin roughly classified the potions he made based on his memory, previous research records, and the results of his research in recent months.
D-grade potions: Made from common ordinary materials, their effects are similar to medicines from ordinary pharmacies, but with better efficacy, faster results, and treatment completed within the duration of one dose. They can treat common fevers, colds, flu, and various allergic issues. There are many such formulas, most of which are recorded in the original body's experimental log.
C-grade potions: Made from more expensive and difficult-to-obtain materials. Their effects are equivalent to high-end drugs or even surgical treatments, and are no longer limited to simple therapeutic effects. This level of potion is what Kevin keeps on hand now.
Among them, two were already made by the original body, two were only left as possible formulas by the original body due to insufficient strength and were completed by Kevin, and one was independently researched and made by Kevin in the past few months.
Truth Serum: As the name suggests, those with weak wills will answer whatever is asked after taking it.
Bone Setting Agent: Also as the name suggests, after the fractured part is fixed, general fractures can be healed within the duration of one dose.
The original body mainly relied on these two potions to make money.
Strength Potion: Increases muscle strength and enhances apparent aura, but accelerates the consumption of stamina and aura.
Healing Potion: Accelerates the healing of internal and external wounds, while consuming stamina and aura.
These two potions were obtained based on the formulas in the experimental records, combined with memories in his mind, and after some adjustments. They can be seen as the result of the combined efforts of the current Kevin and his past self.
Digestion Potion: Continuously consumes aura, accelerates the breakdown and digestion of food, and accumulates energy and nutrients.
This was a potion Kevin developed himself, and its effect was very significant, mainly used to accelerate the effects of physical training.
The specific method of use is to first eat a large meal to the point of being full or even vomiting, choosing high-calorie, high-nutrient "carb bomb" foods.
Then, within fifteen minutes of drinking the potion, these foods will be rapidly digested. After that, high-intensity exercise must be performed to allow this energy to feedback into the body.
However, this way of eating and taking medicine will put a certain burden on the body and cannot be used frequently.
Kevin judged that using it once every 10 to 8 days was relatively reasonable. Of course, depending on individual physique, the interval between uses could be appropriately shortened.
For example, initially, Kevin needed to wait 15 days before he could use it again, but now he can continue after about 10 days.
With this potion, Kevin's physical fitness greatly improved in just three months. But at the same time, a large amount of money was spent on the materials for making this potion, and now he had to continue making potions.
Soon, a potion with a pale green color and slightly turbid liquid, made with materials worth a million, was completed.
"This time it took 40 minutes and consumed about 40% of my aura, which is an improvement from before." Kevin was very satisfied with this. This was also a new use he discovered for the pharmaceutical table: by making the same potion, he could judge his growth based on the time spent and the aura consumed.
Kevin opened the box next to him, which was filled with packaged energy bars.
"Phew, don't try to taste it, just bite it and swallow it." Kevin warned himself, muttering.
After all, to fully utilize the potion's effects, one must consume food with a very high energy density. Besides those high-grade demon beast meats, there were only these special energy bars. As for the taste, it could only be described as "indescribable."
"I eat! I eat! I… *retch*… keep eating!"
Kevin swiftly devoured a box of energy bars like a whirlwind, his face flushed at this point.
"This is the necessary suffering for taking a shortcut, persevere!"
Kevin swallowed the prepared potion in one gulp.
Instantly, his aura burst forth, surging continuously. This aura began to automatically consume itself, accelerating and strengthening the body's digestive capabilities. Kevin's entire body began to turn red and hot.
"Is this essentially also a Nen Ability of the Enhancement type?" Kevin couldn't help but ponder.
The effect produced by the potion, to some extent, was like using Enhancement type Nen to strengthen the body's digestive functions and organs.
Following this line of thought, if someone who wasn't of the Enhancement type used this potion, the effect probably wouldn't be as good as his own?
He wasn't too sure; he hadn't given the potion to anyone else to use yet.
Fifteen minutes passed quickly, and Kevin let out a long breath. The temperature of his body began to drop, and his complexion gradually returned to normal.
But at this moment, his stomach began to rumble.
"Here it comes!"
Kevin, standing next to the toilet, rushed in without hesitation.
Accompanied by a earth-shattering sound, Kevin spent half an hour resolving the issue.
"This too is a necessary price!"
Next, Kevin would face a full day of high-intensity training.
