Chapter 515: Sick Witches

The Flying City—Eureka.

This city, which when flying in the sky occasionally had birds accompanying it and a group of scouts following below, finally welcomed its master today.

Lan Qingyou returned here after disappearing for over half a month.

Everything seemed to be the same as before she left.

But in reality, that was not the case.

The first thing Lan Qingyou did upon returning was to look for Diana.

First, of course, was to hand the Mirage System technology over to her so she could arrange for mass production.

Second, she wanted to understand some of the changes in Eureka City over the past half month.

After all, it was a newly commissioned Flying City. During its initial use, various problems and deficiencies would definitely be discovered.

So the very first thing she did after coming back was to ask Diana.

"It's mostly fine. Apart from some living arrangements, it's mostly just that some people's physical fitness couldn't keep up with the sudden change in altitude."

"Something like altitude sickness?"

Whenever altitude was mentioned, this was the first thing Lan Qingyou thought of.

After all, suddenly going from sea level to three hundred meters high in the sky could indeed cause this kind of problem.

But it shouldn't happen either.

Altitude sickness was a bad habit from Blue Star. In this different world full of magic, because of attribute points, even Transmigrators rarely experienced this situation. How could Witches, who had evolved, still experience it?

"Similar, but not because the air is thin, but because the Mana Density in the air is too high. To put it simply, it's Magic Intoxication."

Diana explained to Lan Qingyou while writing something.

Magic Intoxication...

She had heard of alcohol intoxication, but what the hell was Magic Intoxication.

"After three or four people showed reactions in this regard, I had people investigate. The Mana Density in Eureka City is three to four times that of the outside..."

"Hmm!?"

"Those with higher Constitution points are fine, but those with lower attributes experience a situation where they are groggy all day, lose their appetite, and can't sleep well."

"Ah~~~~ This, I probably understand this."

Based on Diana's description, Lan Qingyou thought of the reason in minutes in her mind.

"You know the reason?"

Seeing that Lan Qingyou actually knew just after coming back, Diana, who originally hadn't planned to put down her pen, involuntarily looked up.

This problem had been troubling her since the day it appeared.

Although it hadn't been long, the number of people with Magic Intoxication was increasing every day. It would be a lie to say it wasn't a headache.

Originally, after investigating, Diana thought that just increasing Constitution would be enough.

So she simply had people put various equipment that increased Constitution on those who fell ill.

However, what she didn't expect was that although their values in their Personal Information indeed increased after equipping these items, it was of no use.

Those who were sick were still sick.

Ultimately, the reason given by Nightingale, the Lantern Witch, was that the attributes of the equipment only increased the superficial attributes.

If the inner attributes of the body were not increased, the illness could not be cured.

Even using attribute potions on these sick individuals yielded the same result.

Thus, unable to find a cure, they could only temporarily let these Witches rest together and have other Witches watch over them.

"I know, I know it all too well."

Lan Qingyou gave a bitter smile.

"This... couldn't have been caused by you, could it."

Looking at Lan Qingyou's bitter smile, Diana seemed to guess something.

"That is indeed the fact, but not entirely."

"How so?"

"You know about Heavy Magic Zones, right."

"I know. Someone proposed this theory on the world channel before."

Diana nodded.

As the Knowledge Witch, such miscellaneous knowledge was her favorite thing.

So even when she was busy, she would ask other Witches to help her collect some as a daily pastime and stress reliever.

This so-called Heavy Magic Zone was hotly discussed on the world channel for a short period previously.

It was spoken of very miraculously.

Saying things like Heavy Magic Zones had huge treasures, or Ancient Divine Beasts living in them, or living in such places long-term could cause one to evolve...

In short, people said whatever came to mind.

Just talking nonsense without paying taxes; most people with nothing to do were like this.

But did this have anything to do with what was happening in Eureka City now?

"After upgrading, the Roosting Giant Tree not only can attract more flying monsters to live there, but it will also gradually increase the magic in the air in its coverage area, slowly turning the area into a Heavy Magic Zone."

"In other words, Eureka is currently gradually becoming a Heavy Magic Zone because of the Roosting Giant Tree."

"And unlike those natural Heavy Magic Zones, there are no natural disasters here. It is an area suitable for living organisms."

Lan Qingyou shared the results she appraised with the confused Diana.

And hearing this result, Diana was dumbfounded.

It's turning into a Heavy Magic Zone suitable for biological habitation?

Indeed, Heavy Magic Zones usually appeared in areas with extreme climates like freezing poles or scorching volcanoes.

But...

"Then what about those flying monsters? Some are weaker than Witches, right."

Yes, what about the monsters?

Never mind the Witches; because of evolution, their attributes had surged once, basically all breaking into triple digits.

But flying monsters were different.

Monsters as small and delicate as sparrows didn't have such high values, yet they showed no adverse reactions, but rather slept even soundly.

This was very puzzling.

"You... haven't dissected monsters before?"

Seeing this Knowledge Witch actually ask such a question, Lan Qingyou couldn't help but be taken aback.

"No, why would I dissect those things?"

"Wait, don't tell me you haven't even learned Alchemy yet."

"How is that possible? I did learn Alchemy."

"...Alright, I probably understand."

Lan Qingyou's mouth twitched.

It seemed this guy was only limited to the 'learned' stage.

But then again, having to deal with so many documents and problems every day, she probably didn't have much time to deeply study Alchemy.

Thinking of this, Lan Qingyou blushed slightly.

After all, this work should originally have been done by her.

But because she acted as a hands-off boss, she threw it all to Diana.

However, because they were now just a single city, and the population had decreased so much, Diana's workload was much less compared to before.

So Lan Qingyou, carrying guilt, began to explain to Diana.

"This involves the physical structure of monsters and humans, or rather the difference between the biology of this world and the biology of Blue Star."

"Although the physical structures of organisms born and raised on the Karim Continent also similarly have internal organs, their skin and muscles as a whole are much more resistant to magic than those of Earthlings."
