Heaven's Arena.
Kevin looked up at the exaggerated building that seemed to have no end in sight.
"This thing is only the fourth tallest in the world," he couldn't help but exclaim. He remembered that the tallest building in his previous life didn't seem as tall as this one.
The technology in this world is really strange.
But after all, it's another world. Even the overall physical quality of ordinary people here is stronger than in his previous world.
It truly lives up to its name as a gigantic arena and fighting holy land.
The surroundings were filled with all kinds of martial artists.
There were those dressed as warrior monks, boxers, swordsmen, and all sorts of different people.
There were also Nen users interspersed among them, though their numbers were relatively small.
Under Biscuit's tutelage, he had already learned how to determine whether someone was a Nen user.
It was by observing whether the aura above their head was naturally dissipating upward. However, he personally felt that such a judgment standard was definitely not rigorous.
Because he himself could absolutely disguise the manifestation of his aura to appear like that of an ordinary person. He constantly kept his aura dissipating upward in this manner.
With his control ability, he could even make it appear as if his aura were loosely leaking like an antenna above his head, while in reality it was still firmly maintaining Ten.
He walked silently through the street.
Kevin began to ponder.
He was no longer ignorant about Nen Ability. In fact, his knowledge in this area already surpassed that of most Nen users.
These were Biscuit's exact words.
Because most Nen users came from unconventional backgrounds, having their Nen awakened through various accidents.
They didn't even understand the Four Major Principles or the Seven Techniques.
However, Kevin was more concerned about his own situation.
Although Biscuit didn't explicitly state it, all the Nen knowledge she had been teaching him heavily leaned toward one aspect.
Restrictions and Limitations.
Post-mortem Nen.
The former was in hopes that he would be prepared when constructing his Nen Ability.
Restrictions and Limitations were actually a form of restraint. By adding restrictions to one's actions or Nen Ability, one could strengthen other effects of the ability.
In Biscuit's words, it strengthened it exponentially. But she warned him not to try it easily.
Because such a thing cannot be restricted simply by wanting to. It requires past experiences. It requires obsession.
More importantly, Biscuit knew that Kevin was not a person with strong obsession.
Even so, subconscious restrictions could still appear during construction. Sometimes a Nen Ability would automatically bind itself.
However, what he should pay more attention to was the latter.
Post-mortem Nen.
It is also related to human will, or obsession. A deep obsession will transform into Post-mortem Nen after death.
This can happen not only to Nen users, but even ordinary people, though the harm is not as great.
Without a doubt, A Moment of Dream was Post-mortem Nen.
Through fragmented memories and laboratory records, he knew that his original self once had a maniacal love for pharmaceutical production.
It was precisely this almost insane obsession that allowed his former self to awaken a Specialization-type Nen Ability highly related to pharmaceuticals.
This also confirmed what Biscuit said. Nen Ability is generated from past experiences and personal will.
And his poor physical learning ability might be related to it. Or perhaps it was a side effect.
Kevin couldn't judge.
Post-mortem Nen becomes stronger after death. That is the manifestation of obsession.
Therefore, the A Moment of Dream he now controlled had changed compared to the one in his memories. It had changed for the better.
But such a change also brought disadvantages.
If his potions were used by others, they would cause side effects.
The stronger the effect of the potion, the stronger the side effects.
Of course, the side effects would not outweigh the main effects.
However, this drawback did not exist when he used the potions himself.
Overall, it was still a golden finger-like existence. Just like his inhuman aura manipulation.

The Laboratory
He returned to the house he rented.
One of the rooms had been converted into a basic laboratory. The shelves beside it were filled with various relatively precious materials brought from his luggage.
He could not bring everything from his old residence. He selected only the expensive and difficult-to-obtain ones. The rest could be repurchased with money.
"Now, let me understand you more deeply."
Kevin rubbed his hands, his face filled with excitement and anticipation.
During the first week, he had not used it recklessly. He had only tested it a few times before stopping.
After all, he did not fully understand it.
And during training, there had been no opportunity. Biscuit's training was truly hellish.
He spread his hands.
A pharmaceutical table with three scales appeared.
He took out an empty potion tube and inserted it into the circular slot at the base.
According to the formula in his memory, he selected three ingredients.
Copper scale: Sun Red Flower (dried).
A herb that excites muscles. Not expensive and easily found in herbal stores.
Silver scale: Fire Duck heart and liver (fresh).
The internal organs of a creature called the Fire Duck, an aggressive wild duck commonly found near lakes. It had strengthening effects.
Gold scale: Evil Tiger Bone (powder).
The bone of a magical beast, the Ferocious Tiger. It could accelerate heart rate, increase blood circulation, stimulate adrenaline, and strengthen muscles.
The three ingredients were placed on the scales according to their roles.
The gold scale held the main ingredient. The potion's core effect would be based on it.
The silver scale held the auxiliary ingredient, strengthening or adding additional effects.
The copper scale held the fusion agent. It determined whether the mixture would stabilize or collapse.
If an unsuitable fusion ingredient were chosen, the result could be poison. Or useless wastewater.
Moreover, the materials must belong to him. Whether something belonged to him was judged entirely by the subconscious. Self-deception would not work.
Everything was ready.
Text appeared on the base. This feature had not existed before death.
"Increase muscle strength. Increase visible aura. Accelerate stamina and aura consumption."
Kevin entered a state of Zetsu, and all visible aura surged into the pharmaceutical table.
The strength of the potion determined how much latent aura was required and how long refinement would take.
Visible aura was maximum output.
Latent aura was total internal capacity.
To put it simply, a person was like a water gun.
Latent aura was the size of the tank.
Visible aura was how much water could be shot out at once.
This potion was not particularly strong. The time required was not long.
The required production time was one hour.
Kevin sat quietly in the dim laboratory, watching the scales slowly descend.
For the first time since arriving in this world,
He felt completely in control.
