Don't provoke mentally ill people in the infinite flow genre!

When Yi Zanglan looked up, she saw a girl in a school uniform hanging swaying from the ceiling of the corridor.

It was suspended above by a hemp rope, its collar loose, and its neck twisted to one side by the rope.

Disheveled long hair covered half of her face. She lowered her head, and you could vaguely see that she was wearing a pair of thick, high-prescription glasses. Behind the lenses were a pair of dark, sinister eyes with almost no whites visible.

Click, click, click.

Its toes dangle in mid-air, swaying gently, just enough to kick the shoulder of anyone passing by.

The rope dragged on the ground, thumping against it with each movement, making a soft sound.

It is also black and white, completely blending into the mirror world, making it look even colder and more eerie.

...The two stared at each other, and it stared intently at Yi Zanglan. The hand hanging at its side had somehow acquired a fountain pen.

The next second, the sharp pen tip gleamed coldly, pierced the air, and suddenly stabbed fiercely towards Yi Canglan.

In the blink of an eye, Yi Zanglan nimbly dodged to the side, the tip of the pen grazing her earlobe, sending a chill down her spine.

She drew the fruit knife from her waist and swiftly parried the opponent's second attack. With a clang, the pen flew from the ghost's hand and landed by the door.

Wu Ying reacted quickly, bending down and sliding to grab the pen and stuff it into her pocket.

"Let's go upstairs!"

The two ran all the way to the fourth floor, only to find the female ghost chasing after them relentlessly. The rope did not restrict her movements at all; instead, it allowed her to scale walls and rooftops, blocking them from all angles and preventing them from getting close to the reading room at the end.

Even without the pen as a weapon, the female ghost's fingernails were still sharp. She even had a long, flexible tongue, a feature usually found on hanged ghosts, which was as lethal as a whip, leaving a bloody welt whenever it struck.

Wu Ying's movement was affected by the bookshelf, and she was accidentally slapped on the tongue, causing blood to seep from her shoulder immediately.

But in the mirror world, the blood is also grayish-black, like ink slowly spreading.

She cursed under her breath and, in coordination with Yi Zanglan, attacked from both sides. The blade of the fruit knife grazed the female ghost's tongue, causing no real damage, but it still managed to slow down the opponent's attack speed.

"This can't go on like this," Yi Zanglan suggested. "I'll lure it away first, and you can go invisible and find that bookshelf to see if there are any clues."

"……OK."

As things stand, this is indeed the most feasible solution, so Wu Ying did not refuse.

Just as she was about to activate her skill, she suddenly heard a series of hurried and heavy footsteps coming from the corner of the stairs, accompanied by a familiar, nonchalant male voice.

"Old Shen, did we end up inside a mirror or a black-and-white TV? Logically, now that we're in, there should be some kind of test, right? How come we're already on the fourth floor and still... oh my god! A ghost! Captain! An assassin!"

Before he could finish speaking, Qin Shaoyu had already dashed into view, and due to his excessive speed, he came face to face with the angry female ghost.

He was immediately terrified and dodged backward like a spring, spouting nonsense as he did so.

Shen Yubai was caught off guard and almost tripped over the impact. He quickly grabbed the man by the collar and threw him aside before he could see what was happening in front of him.

"...Lanlan, Xiaoying!"

At that moment, Yi Zanglan quickly assessed his teammates' skills and decisively issued the order.

"Old Shen, light the incense!"

[System prompt: Use skill [Shadowless Incense]? Three incense-burning opportunities remain for this round.]

【Yes. 】

Shen Yubai immediately followed up upon hearing those words, activating his skills without hesitation.

Brown incense sticks appeared between his fingers, producing a faint herbal scent as they burned. He grabbed Qin Shaoyu and quickly moved closer to Yi Zanglan and Wu Ying, signaling everyone to gather around.

"Don't stray too far from me, and don't run into any ghosts, or the incense will lose its effectiveness," he whispered. "Let's slowly make our way to the reading room."

So the four of them automatically huddled together, carefully wrapped the incense stick around it, and walked in circles through the corridor toward the reading room at the end.

The female ghost lingered nearby, her eerie aura searching everywhere, but due to the skill's effect, the four of them essentially vanished from her sight.

"We're really on the same wavelength." Qin Shaoyu took a moment to chat. "Old Shen guessed that the captain would head towards the boys' dormitory, so I suggested the library. Turns out you guys were here, and even arrived before us."

"That proves your luck influenced us to some extent too." After saying that, Yi Zanglan asked, "There should be a hint at the beginning, right? What token did you get just now?"

"Basketball," Shen Yubai replied. "According to the newspaper, a student was once killed by a basketball court. The student's resentment was not over, and he would always wander around at night. We found a way to shoot a three-pointer for him, and he left."

"Yes, we helped a female classmate who was being bullied retrieve her backpack that had been thrown in the bathroom." Yi Zanglan nodded. "Once we solve this problem, we'll have three tokens in our possession."

The tokens at the beginning are relatively simple, but the tokens become increasingly difficult to trigger as you progress, and the difficulty of obtaining them will likely increase accordingly.

The four of them finally opened the door to the reading room at the end of the room. Unexpectedly, from the moment they entered, as if influenced by some force, the burning speed of the incense stick in Shen Yubai's hand began to increase silently, roughly estimated to be more than seven or eight times faster.

At this rate, it will burn out in at most half a minute.

"Hurry up!"

The four of them arrived at the last row of bookshelves and saw that the shelves were already neatly filled with books. In the space where there had been a gap, there was a ghostly notebook with a gold-embossed hard cover.

This notebook stands out because, in the completely black and white image, it is the only one where the gold patterns on the spine are still visible.

Yi Zanglan pulled out the book, opened it to the first page, and saw only four characters on the blank page:

your name.

Below that is a horizontal line, which should be a place for players to fill in the blanks.

It's obvious that the four of them need to sign here.

"Xiaoying, where's the pen?"

So that's what the pen I just got from the female ghost was for.

Wu Ying quickly took out a pen from her pocket and handed it to her. Yi Zanglan took it and signed the names of the four of them on the horizontal line with her elegant handwriting.

Yi Zanglan, Wu Ying, Shen Yubai, Qin Shaoyu.

As she finished signing the last character "羽", the incense stick in Shen Yubai's hand went out.

A subtle ripple spread through the air once more, and the bookshelf in front of me melted like wax, until it transformed once more into a square frosted mirror.

Almost at the same moment, the female ghost behind them locked onto their presence and flew at high speed through the air, crashing down on the four of them like a mountain.

"Walk!"

Yi Zanglan and Wu Ying decisively entered the mirror, and Shen Yubai first threw Qin Shaoyu in before following closely behind.

Because he was a fraction of a second too late, just before he was fully inside the mirror, he suddenly felt a sharp pain in his back and was unfortunately slapped on the tongue by the female ghost.

……

Half a minute later.

The four of them lay down in front of the bookshelves in the reading room, which had been restored to normal, and after catching their breath, they checked on each other to confirm the situation.

"Hey, are you alright, Lao Shen?" Qin Shaoyu lifted Shen Yubai's coat to examine the bloodstain. "This is the first time I've seen a ghost's tongue so powerful. Is the library really your nemesis?"

"To be precise, the mirror is my weakness," Shen Yubai said with a smile. "But it's alright, you didn't change my talent this time, so my damage tolerance is still there. These minor injuries are nothing to worry about."

"...Brother, you're my own brother, didn't we agree not to mention it? The captain's still here, please give me some face!"

Yi Zanglan calmly said, "I'll pretend I didn't hear about what happened between you two."

"Thank you, thank you!"

On the other side, Wu Ying approached the bookshelf to check and found that the previous gap had been filled.

The supernatural notebook with its gold-embossed hard cover had been perfectly fitted inside.

She pulled out the book, turned to the first page, and saw that the four signatures were still there. Then she suddenly felt her watch vibrate; it was a system notification.

Because she picked up the book first in the world outside the mirror, this keepsake was registered in her name.
