In the past year, his only gain in combat was an attribute point he received at "Doctor" level 3, which he added to his physique, curing his obsessive-compulsive disorder.
"Dr. Aoki!"
"Dr. Aoki, are you seeing patients today?"
"Long time no see, Dr. Aoki."
Walking through the hospital, Aoki was constantly greeted by people.
His status here was quite high.
This wasn't due to talent or medical skills, but mainly because of his close relationship with the director, Tamayo, making him the only person who could freely enter and leave Tamayo's laboratory.
Although there was a possibility of being called a gigolo, Aoki didn't mind; instead, he actively exercised his privileges to increase his experience gain speed.
After a busy day, gaining 10 experience points, Aoki finished his work for the day after it became completely dark.
He didn't feel tired and decisively chose to go home.
Firstly, he wanted to act like an ordinary person; secondly, there were fewer patients at night, making it less efficient.
He declined two colleagues' invitations to go to an izakaya and directly used "space teleportation" to return to Shiroi Town.
His master's wife and Takina were already used to his sudden disappearance and reappearance, and didn't even ask him anything.
After chatting with Takina and his master's wife for a while, Aoki returned to his room and pondered the problems he currently faced.
His ultimate goal was to regain his human form while retaining his demon powers.
Achieving this goal through research was hopeless in the short term.
Others might give up, but he had one more thing to rely on:
the system!
According to Tamayo, the origin of demon power was too profound; with current technology, there was no way to unravel it.
Even after Aoki described the potential future developments and changes in the medical industry, Tamayo's answer remained the same: impossible.
As for separating the power and characteristics of demons, it sounded like a fairy tale—unrealistic, but upon closer examination, it was indeed true.
The system, however, possessed the power to turn the impossible into possible.
With the system's help, he shed his craving for flesh and blood, becoming stronger by killing demons. In just one year, his strength surpassed that of Muzan Kibutsuji.
When in trouble, turn to the system—isn't that common sense?
However,
to achieve the goal of "wanting both" in a short time, he inevitably needed extraordinary power.
And this world only had two kinds of extraordinary power; he couldn't yet control the other, the Breathing Technique.
In other words, if he wanted to solve the problem with the system's power—he had to go to other worlds.
"This is troublesome!"
Aoki rubbed his temples.
He was certain that other worlds existed.
Because he had transmigrated from another world.
But where those worlds were, and how to get there, he had no clue.
No.
Not entirely clueless, just a guess without any certainty.
The more Aoki thought about it, the more unreliable it seemed.
Even if he could travel to another world, how would he return?
How much time would it take?
Would he gain the power he desired in other worlds?
What about safety?
These were only a small part of the questions he considered.
"Let's wait and see. Once a decision is made, there's no going back! I can use this time to accumulate more power."
Aoki temporarily suppressed his impulse.
The next day, he continued working as a doctor.
Two months later,
Aoki finally accumulated enough experience to reach the maximum level of "Doctor," a total time exceeding one year—the longest of the four professions he had completed.
He used the final skill points to learn the last "Doctor" skill, and allocated his free attribute points to Strength, reaching 29 points, just shy of 30.
Although he had reached the maximum level of "Doctor," it didn't mean he was the strongest doctor.
Half-star profession skills enhance talent, not directly improve professional abilities.
Simply put, whether it's a doctor, martial artist, or hunter, the system's role in the profession is to transform an ordinary person into a genius in that field.
To become an expert, all knowledge and skills must be learned personally.
The system can't help with that.
As a doctor, Aoki's level was already quite excellent, but far inferior to Tamayo and Kanae Kochō.
He had the talent to catch up with, and even surpass, theirs, but that would inevitably require a long period of study.
If he had enough time, he wouldn't mind delving into medical studies and becoming a medical master.
However, now that he had a higher goal, he naturally didn't intend to waste time on that.
In most cases, medical skills, or rather, being a wet nurse, are crucial.
But as a demon, he possesses his own spring water, making him one of the few who doesn't need it.
Aoki immediately threw himself into his next task, attempting to acquire another profession.
This time, he chose chef.
However, unfortunately, he failed.
He simply couldn't obtain the chef profession.
This time, it certainly wasn't his instructor's fault; through Ubuyashiki Kagaya, he found one of the most famous chefs in Tokyo to teach him.
Finally, Aoki discovered that the reason was likely his inability to taste.
The importance of taste to a chef is self-evident.
This also made him realize that a profession cannot transcend one's fundamental conditions.
For example, he obtained the "Oni" profession only after acquiring Muzan Kibutsuji's blood.
If he remained human, he would never be able to acquire the "Demon" profession.
In that case, his inability to master breathing techniques becomes understandable.
Because breathing techniques are based on the human body's structure, they are not applicable to demons.
In other words, the system merely professionalizes the powers he possesses or can possess; it cannot create powers out of thin air.
Based on this, Aoki then tried to obtain the "Sprinter" profession.
"Chef" was out of interest, while "Sprinter" was considered as potentially helpful in combat.
He failed again.
Afterwards, Aoki analyzed the reasons, guessing it was probably because his physical strength was too excessive.
If he wanted, he could easily win in every sport in the world that required physical prowess.
He didn't need a profession; he was already the strongest.
Acquiring a profession, besides being based on physical conditions, also had to conform to realistic logic.
Given his situation, to increase his success rate, it would be best to choose a half-star profession that emphasized skill.
Looking back, obtaining "Martial Artist" was truly a close call.
Although the two consecutive failures took some time, he summarized two key patterns, so it wasn't a waste.
However, Aoki didn't have time to try to acquire a profession again because the time of year with the strongest sunlight was approaching.
