Fairy Tail: Vector Manipulation

After carefully examining the man's wound, Chen Fan said with exaggerated concern, "Hmm, let me see... Wow, this cut is really deep. It might affect your ability to cast magic in the future."

His expression suddenly turned serious as he continued in an alarmist tone, "More seriously, it could affect the advancement of your magic power in the future. After all, the body is the channel for magic power. Without a good physique, how could you support that filthy soul of yours?"

After saying that, he realized something was off, as though he had misspoken. He coughed twice and said, "Cough, cough. Um... I mean, without a strong physique, you can't support powerful magic power."

But the man had focused all his attention on the words "unable to advance." His face went blank, and he did not hear anything Chen Fan said afterward.

"Then, Chen Fan—" Before he could finish, Chen Fan raised a hand and interrupted him. "Don't call me Chen Fan. When I'm treating patients, call me Doctor."

"Then, Doctor, can this wound of mine really be cured?" The man before him looked nervous, staring fixedly at Chen Fan, terrified that the word "no" might come from his mouth.

"No problem. It's a minor matter. Since this is my first day in business, I'll only charge you 10 J," Chen Fan said generously.

"Ten J? That's really cheap." Hearing that Chen Fan could cure him and was charging so little, the man nearly jumped for joy.

"Don't be so happy yet. Have you recently felt that your magic power has been progressing more and more slowly?" Chen Fan said with a sigh.

That grave tone brought the still-celebrating man back down. He responded to Chen Fan with a nod. "Yeah." Wasn't that obvious? How could magic power be so easy to improve?

Chen Fan leaned back in his chair, closed his eyes, and held his forehead as though he had a terrible headache. The man became so nervous that he could practically hear his own heart pounding.

About a minute later, Chen Fan opened his eyes again and said, "Based on my many years of medical experience, you have... cancer!"

"What is cancer?" Hearing Chen Fan say something that sounded so serious, the man asked anxiously.

"Cancer is an extremely stubborn disease. It lies dormant in a person's body, usually showing no abnormalities, but it erupts at critical moments. The cancer in your body was likely caused by repeated injuries that never received proper treatment, resulting in muscle necrosis, damaging your bodily functions, and reducing your coordination... In severe cases, it can lead to loss of sexual function."

Chen Fan rattled off a string of professional terms that left the man completely bewildered.

"Then what should I do?" Seeing that the man was so anxious he was nearly in tears, Chen Fan knew the time was right. The bait had been cast; it was time to reel in the net.

So he said, "Don't worry. I can cure you, but such a major operation will consume my life force. Sigh... For the sake of others, I suppose I can only sacrifice myself." He sighed, his face shining with the noble radiance of self-sacrifice.

The man was deeply moved. In the end, he dazedly handed over 100,000 J before walking out with excitement written all over his face.

Of course, Chen Fan had already healed the injuries on the man's body with his ability. No matter how black-hearted he was, he would still do what he had promised.

As soon as that man came out, the others crowded around him, asking all sorts of questions. Most were simply there to watch the excitement, though some genuinely wanted to know how skilled Chen Fan's medical treatment was.

And the man kept praising Chen Fan's medical skills, talking about how brilliant they were and how cheap his fees were. In short, he only had good things to say.

Then Chen Fan's voice rang out. "Next."

A crowd of people rushed toward Chen Fan, their expressions somewhat fierce. After much difficulty calming everyone down, Chen Fan sped up his treatments. He no longer acted like he had with the first patient. His reputation had already been established, so there was no need to make things so troublesome afterward.

Whenever someone came, he would ask, "The big one or the small one?"

Since they had all learned outside what Chen Fan meant, they clearly stated that they wanted the "big one." After quickly finishing the treatments, Chen Fan discovered that he was exhausted. Maybe it really was as he had said: His current physique couldn't support that filthy soul of his. No, that was wrong—it was his pure soul.

Though he was exhausted, it was not without benefits. Chen Fan could clearly feel his fusion with this body improving. Perhaps before long, he would be able to begin developing the brain.

After all, the human brain was extremely complicated. A single mistake could lead to unimaginable consequences. If things went badly, it would be just as he had told Makarov. He did not dare take that risk.

Like an unlicensed street vendor selling fake medicine who had spotted the police, Chen Fan hurriedly packed up his stall. Raising a hand, he called out, "That's all for today. We'll continue tomorrow. I'm out of magic power."

"No! You treated all of them. It's almost our turn—how can you just leave whenever you want?" A group of people stretched out their hands to block Chen Fan's path. They looked like police officers trying to drag Chen Fan to the station, leaving him thoroughly helpless.

Suddenly, a voice shouted from the doorway, "Erza is back!"
