The old man you see with your phone is highly suspicious.

He walked in and saw the familiar decorations, the familiar layout, even the familiar shelves and books. It seemed to be a one-to-one replica of the academy's library. Faust silently walked in.

"Harley, it's you! You're back so soon?" The person organizing the books seemed to be a boy who was a little over 1.7 meters tall.

He looked quite young, dressed impeccably like a gentleman, with a pocket watch clipped to his chest and a monocle held in the socket of his right eye.

He is Mephisto, the only god of this world, and also the 12th Apostle of the Council of the Mist.

Judging from his current appearance, no one would guess that he is the demon who turned the world into what it is today. In fact, in terms of clothing and style, he is almost identical to Faust.

It's the kind of thing that even Xue's Law would criticize – the exact same style of dress and taste, showing how deeply Faust influenced this student.

“Hmm,” Faust responded, while simultaneously beginning to completely disguise his expression and demeanor as Harley Alban.

"Is something the matter? Today should be the day you just got home. You're back so soon, something must have happened." Mephisto pulled out a book, looked at it, and seemed to reveal a nostalgic smile.

A Detailed Explanation of the Fundamentals of Mysticism

He wiped the dust off it, then took it out, slowly unfolded it, and held it like a precious treasure.

“I have found the Book of Soya,” Faust said directly.

"Clap!"

Mephisto dropped the book from his hands in an instant. He stared in shock at the "Harley Albann" before him, completely losing his composure: "Really? How is that possible? My teacher should be dead..."

“Yes, this is a Noble Phantasm. It appeared when another child awakened his innate magic. He gave it to me first, and I think this is what you want.” Faust said, handing him the Book of Soya.

Mephisto silently accepted the book, and only after he opened it did he realize that it was genuine, because his own handwriting was still visible on it, just like it had been years ago.

"Thank you, Harry."

"Stay here tonight."

……

Faust was quite satisfied with the toxins in his body, because even he, now the "owner" of this body, could not detect them.

After all, this is not a poison in the traditional sense, but a bacteriophage.

The so-called bacteriophage is just a specific RNA molecule. Although this RNA molecule has been modified from the God Tree Special Attack, it still cannot get rid of its underlying code.

This allows RNA to be dispersed throughout the cell without anyone suspecting anything, since cells themselves contain a large amount of scattered DNA and RNA, which is simply the underlying code of humanity in this world.

Before those RNAs combine to form bacteriophages, no one can detect its abnormality, not even God.

This is actually a case of "blind spot," using the messy RNA of the cell's own "shit code" to hide the real killer move.

To maintain secrecy, Xue used cursed blood to modify the bacteriophage into its current form.

When these bacteriophages hidden in the cells enter Faust's body through fluid exchange, their detonation will be like a durian being forcibly stuffed into his body, giving him a huge surprise.

Just as Faust was pondering this, Mephistopheles came out, and by candlelight, the two of them, like an old married couple, prepared to do something on the bed in the library.

This was something Faust couldn't understand at all. Why, given the current situation, was Harley and Mephisto already an old married couple, yet Harley was still a virgin?

How can it be?

Faust couldn't understand it, but he didn't dwell on it. Instead, he began to slowly remove his clothes, following Harley's habits.

Lanterns swayed in the library.

But the next moment, Faust's pupils contracted, because he was horrified to discover that Mephisto actually had breasts!

No, that's not all. He only just realized that his student was not male, but female!

In that instant, Faust understood everything he hadn't been able to comprehend before: why Harley was still a virgin...

But, impossible, absolutely impossible!

He knew Mephisto was male because the boy had come to his academy at the age of eight and become his student. When the boy was young, he was both his teacher and a father figure to him.

Even when Mephisto was seriously injured, she took care of him for more than a day, and even helped him to the toilet. How could she not tell whether the child was a boy or a girl?

But why is Mephisto now a woman?

For a moment, Faust's mind was filled with what felt like a cosmic explosion. He was so engrossed in his own expression that he was completely oblivious to his surroundings. His face was contorted, and he looked as if he had seen a ghost.

How could this be! How could this happen!

Impossible, absolutely impossible. Why would this happen? Could it be that Mephisto was switched with someone else long ago? Could it be that my student is no longer me? When?

It must have been before he became a god, otherwise Mephisto wouldn't have been able to hide it from his teacher.

And why would this happen?

What happened to this student that even he himself didn't know about?

"What's wrong, Harley?" Mephisto seemed puzzled.

"It's nothing. Do you have time tomorrow? Let's go back to the family together," Faust replied casually.

"Okay." To everyone's surprise, Mephisto agreed to the request.

Faust fell silent. He suddenly realized that the gender-changing drug was Mephisto's creation. The reason why this drug could be so widespread, even used on the lowest levels of society, was not because the potion was ineffective, but because it was so easy to make. Even the lowest-level gang workshops could produce gender-changing drugs.

All it takes is the blood of a courtesan, along with some simple hay and bark, to create a gender-swap potion through alchemy.

Now, he fully understands the origin of the sex-changing drug.

The source of this potion lies in one of his students!

It's even possible that one of my students is the first person in the world to use sex-changing drugs!

No, or rather, the gender-changing drug itself is a ritual based on Mephisto, a kind of ritual that resides within a magic potion!

……

The Akatsuki organization began to grow rapidly.

Several cities were once again occupied by other Akatsuki members who were also missionaries. This time, they were no longer as arrogant as they were in Roland City. Instead, they gradually went underground and began to expand their manpower and network. At most, they would only deal with some gangsters who came to cause trouble, but they would not arouse the fear of other nobles.

This is because they need to recruit most of the underprivileged children in one city into their own group, and then quickly move on to the next city to recruit more people.

Time waits for no one. If they are a step behind, more cities will be taken over by their colleagues. They now deeply understand what it means to be enemies with your competitors. Many people, after establishing a foothold and developing their first batch of downlines, rush to the next city without stopping.

Once your downlines have experienced the benefits of recruiting others and increasing their power, they will desperately recruit more people to join the organization. However, the performance of their downlines will only be counted towards your own. This makes the strategy of recruiting downlines and then running away the most suitable for rapid development.

As a result, just like a land grab, the number of Akatsuki members began to explode exponentially.

Meanwhile, Xue Dinglu stayed home all day and stopped causing trouble.

But all of this seems to be the calm before the storm.

Chapter 399 Mephisto's True Identity

The following morning, Xue Dinglu did not sleep. He spent a lot of time preparing for this battle, which would be a direct confrontation with an apostle on his home planet.

Although he chose the safest and most despicable approach, Xue Law still felt uneasy and began researching gender-swap potions all night long.

This is the most unique potion in the world, and it's something Xue Dinglu had to face as soon as he arrived. It almost caused him and Su Su to stop being brothers and instead become best friends because of it.

Even according to Xue's Law, this thing seems very unreasonable, because the materials needed for a fairy that can completely reverse a man's gender are so simple.

According to Faust, sex-changing drugs could be produced even in a small workshop, and once ingested, a man would be irreversibly transformed into a male.

Isn't this a bit too extreme and too fast?

Xue's Law knows that there are many races and creatures in the universe that can change their gender, but humans are definitely not among them.

In other words, among all the humanoids in the universe that are evolving towards the concept of a supreme ruler, it is absolutely impossible for such a strange race to exist.

Furthermore, according to Faust's information, there were absolutely no sex-changing drugs or similar things in this world before.

Mephisto was the creator of the sex-changing drug.

After Xue's Law separated and purified the cursed blood, he discovered that the sex-changing drug was essentially just a strange liquid mixed with blood, and did not even contain any trace of magic.

However, the fact that this non-magical creation could so easily change the gender of the locals seems less like a magical phenomenon and more like a higher form of rule.

In other words, after taking the potion, it's as simple as changing the gender of a unit from male to female directly in the background.

This is why Xue's Law remained a mystery after studying it all night.

"Brother, what are you doing?" Su Su, whose stomach was growling with hunger after waking up, immediately picked up a piece of bread and started munching on it, while looking at Xue Dinglu with a puzzled expression.

“I’m researching the connection between gender-swap potions and world consciousness. At the same time, I’m conducting joint tests on gender-swap potions, Mephisto, and world consciousness. Haven’t you noticed that we’ve been in this world for several days, but we’ve never sensed the existence of world consciousness?” Xue Dinglu said.

"Hmm, that makes sense. Planets with life usually have something similar to Margaret, right?" Su Su asked.

"Based on my experience, yes, planets with life have a world consciousness. This is a common phenomenon. Even if there is no world consciousness, there are beings that can assume the responsibilities of world consciousness, such as divine trees in the form of the World Tree."

"And this world definitely has a world consciousness. After all, Mephisto was essentially a transmigrator from Earth, and was even taken away by this world. But neither Faust nor we have discovered the world consciousness of this world." Xue Dinglu took a deep breath, separated the materials for the gender-changing drug, and said,

“And now, this unreasonable magic potion seems to be a rule of the world, the work of the world's consciousness,” Xue said, then removed the other ingredients from the gender-swap drug and randomly added some other plants and wood ash.

After the newly concocted potion appeared in his hand, Xue Luding went out and casually grabbed a male bird, then fed it the new version of the sex-changing drug, but it had no effect.

But yesterday, when Xue Daolu casually knocked out an unknown male nobleman from the Alban family, and secretly dragged him back to his room to feed him this haphazardly prepared sex-changing drug, his body immediately began to change into that of a woman, and his chest seemed to tear his clothes in an instant.

This left Su Su completely dumbfounded.

Now, Xue's Law is beginning to record the rules of sex-changing drugs.

1. Gender-swapping potions contain no trace of magic.

2. Sex-changing drugs are only effective in human males.

3. Men who take sex-changing drugs are no different from women and can get pregnant just like them.

4. Sex-changing drugs do not cause organ degeneration, but rather transform human organs in a way that is similar to distorting them towards female characteristics, thereby achieving a process of sex reassignment in a short period of time.

5、服用性转药之后，阉割后的男性会在30分钟~2小时就迅速转化为女性，而未阉割会在5小时~7小时左右转化。

6. The gender-swap potion causes secondary characteristics to grow abnormally.

……

Therefore, after recording this, Xue's Law had an extremely bold idea.

"The source of the sex-changing drug is actually the world consciousness. It is consciously and forcibly converting all men into women. As for the reason... we don't know," Xue Dinglu said.

"It seems that the root of the chaos in this world does not lie with that apostle, but with the world itself," Xue Dinglu stated, revealing this conclusion.

Su Su was filled with questions and couldn't understand what Xue Dinglu was saying at all. She looked at the bread on the table and decided to eat first.

“It’s okay, you can continue eating,” Xue Dinglu said.
