Sister, can I be the scabbard too?

As is widely known, knowledge comes at a price, which is a core setting of the Cthulhu universe.

In other words, the more one knows, the more pain one experiences.

Lin Yuan initially scoffed at this statement.

Until the system told him that the group of maids wearing black and white stockings on the way to the library were all Xiao Nanliang!

"What a tragedy!!!"

Lin Yuan's lips twitched as he looked at the maid in front of him who was speaking to him in a coquettish voice and inviting him to sit in the coffee shop.

As a first-year student at Miskatonic University, you are on your way to the library.

But just then, you discover that a group of Sirens have broken into the University of Michigan!

The Siren's offspring are terrifying creatures from the void. They are male, but often disguise themselves as women or armed helicopters to gain the trust of their own kind and absorb their spiritual energy.

[Choose one: turn a blind eye and watch them deceive human men, draining their spirits.]

[Let's get involved ourselves and see whose sword is sharper!]

"..."

Lin Yuan didn't speak, but silently took out his phone and sent Zhang Xiaobai a message via Fetion:

"Hey bro, a new maid cafe just opened outside the school. They're handing out flyers at the library entrance. I checked it out for you, the girls are really high quality."

Zhang Xiaobai's reply came quickly.

Zhang Xiaobai: The big smiling emoji.

Zhang Xiaobai: "Instead of going on a blind date, you went to a maid cafe? Hajiyuan, you rascal, be careful I tell the counselor about this."

Lin Yuan: "I signed up for a membership, and I left your phone number."

Zhang Xiaobai: "Dad, don't worry, I'll take care of the blind date. No one will know you didn't come."

Lin Yuan put away his phone and gave a crooked smile.

Zhang Xiaobai is his brother, his beloved friend and family. How could he not leave such a good thing as Nanliang Coffee Shop to him?

Besides, it's just a membership; you don't need to deposit any money.

You'll even get a free electric mini fan if you register successfully.

Ah, what a great host! It's unbelievable.

Instead of choosing one option, create one.

[You have led the repressed seeker to the territory of the Sirens' offspring, inciting conflict between the two sides.]

[And you, hidden in the darkness, sit back and watch the tigers fight.]

Such immense power, in short, is that you alone reign supreme in heaven and on earth.

[You have gained 1000 Universal Points, your sanity has increased by 100 points, and your physical attributes have increased by 10%.]

[Your SAN value has reached the minimum requirement for learning arcane spells. Please go to the library to study them immediately.]

"No, this works too?"

Lin Yuan's pupils dilated.

It seems that this system has a high degree of freedom.

At least there are no restrictions on how the task can be completed.

Lin Yuan suddenly had a feeling.

It seems I've really turned Earth Online into something else entirely.

However, the worldview has become Kryptonian.

After bidding farewell to the Happy Yuanyuan Clan, Lin Yuan headed towards the Maid Cafe—no, the Library.

As he walked, he opened the panel.

Name: Lin Yuan

Age: 18

Gender: Male

[Identity: First-year student at Miskatonic University.]

SAN value: 300

[Universal Points: 2000]

To be done:

[Esoteric Practice (Go to the library to begin practice)]

Promotion assessment (not yet unlocked)

Exorcism Request (Unlocked)

Outpost (not yet unlocked)

[Old Shop (Not yet unlocked)]

"It has quite a few functions." Lin Yuan raised his chin.

The old shop can be unlocked by accumulating 5000 points.

He already has 2000, which shows that it doesn't take long to accumulate.

As for the other items, based on his years of experience playing mobile, PC, and console games, they should be unlocked gradually as his strength increases, so there's no need to rush.

The most urgent task now is to learn the secret techniques and become a superhuman as soon as possible.

"oi, Lin Yuan."

Just then, a familiar voice rang out.

Lin Yuan snapped out of his daze and saw a female teacher in a white coat walking out of the library.

The female teacher wore a white shirt and a long skirt under her white coat, with black stockings and five-centimeter high heels underneath.

She has very light makeup, a high level of beauty, and a cold expression; she is a natural-born cold-faced beauty.

But the moment Lin Yuan saw him, he didn't have any impure thoughts. Instead, he shivered like a mouse seeing a cat.

This woman's surname is Bai, given name is Wuchang, she is 25 years old, a graduate student at Suzhou University, and also Lin Yuan's elective course teacher, teaching theology and philosophy.

But she has another identity—the older sister who lives next door to Lin Yuan.

Lin Yuan died young, losing both his parents when he was six years old.

Although they received a large sum of compensation and were financially secure, the children still needed care.

This important task fell to his neighbor, Professor Bai, the president of Suzhou University, who was also a close friend of his parents.

And Bai Wuchang is Principal Bai's daughter.

Bai Wuchang is 7 years old in Dalinyuan.

Who would have thought that when Lin Yuan was 6 years old, she was already 13?!

Lin Yuan really liked this older sister from next door.

After all, Bai Wuchang was an excellent student, whose grades had never fallen out of the top three in the whole school since childhood, and he took good care of his younger brother.

Every few days, they would come to my house to tidy up my room and prepare some meals.

Even during my rebellious middle school years, when I didn't want to live at school, he used my living expenses to help me rent a place off-campus.

In Lin Yuan's mind, apart from having a cold face, being a bit rigid, and having a mind full of studying, Bai Wuchang had no flaws.

But all of this changed on the day Lin Yuan turned 13 and Bai Wuchang turned 20.

That day was a Friday. In order to give Bai Wuchang a birthday surprise, Lin Yuan deliberately did not go back to his rented room, but bought a cake and went home instead.

On that very day, he saw the 20-year-old White Impermanence hiding in his room, reading a magical girl comic book.

If it were just for looking, that would be fine.

She even bought merchandise related to the transformation device and cosplay outfits, and on Lin Yuan's bed, she performed a magical girl transformation while striking a wooden fish in front of a picture of Jesus:

"God, oh Nege, please let me become a magical girl!"

If that were all, it would be fine.

The scariest thing is that the magical girl she plays is the magical girl from "I Want to Be a Magical Girl"!

What's even more terrifying than the worst part is that Bai Wuchang was so engrossed in the moment that she didn't notice Lin Yuan behind her, witnessing the whole thing.

By the time Lin Yuan and she realized what had happened, it was too late.

That day, Lin Yuan's face showed the expression of Sasuke.

What on earth is this guy doing?

It was also on that day,

Lin Yuan finally recalled the fear of being controlled by Bai Wuchang.

All the memories of the past flooded my mind, and a thousand words could be summed up in one sentence.

"Hello, Sister Bai."

"How many times have I told you? You must call me 'Teacher' when you're outside." Bai Wuchang frowned.

"Hey, what are you doing at the library? Isn't there only one final exam left? And it's open-book."

"Well, I'm about to be a sophomore, so I'll study my major courses in advance and cram a little." Lin Yuan scratched his head.

"Wow, you have a foot fetish?" Bai Wuchang was even more surprised.

Lin Yuan: ? ? ?

What?! He has a foot fetish? He should apologize to Buddha and Jesus! You woman who dreams of becoming a magical girl!

Lin Yuan originally wanted to argue with Bai Wuchang,

But suddenly, she saw a girl with white hair, white eyes, white eyelashes, a white dress, and even almost white skin.

As I passed behind Bai Wuchang, I tripped over my own feet and fell to the ground. Then, as if it were nothing unusual, I got up and walked into the library.

[Great host, perhaps a pig-headed teenager won't meet a bunny girl senpai, but a freshman at the University of Michigan might just encounter a naturally ditzy, socially awkward witch.]

You have encountered the corrupted witch, Tang Feixue.

Now, make your choice.

To flee or to fight?

[Upon successfully defeating the Fallen Witch Tang Feixue, you will receive 10000 Universal Points and your SAN value will increase by 1000.]

When the corrupted witch Tang Feixue falls deeply in love with you and prostrates herself in apology, you can transform her into the god-slaying weapon, the Sword of Corruption.

Witch?

Corruption?!

Falling on flat ground?
