The staff room in the subway station is next to the toilet on the other side of their location. Although there was still some distance between them and them, it only took a moment for the two of them to come to the door of the staff room.

The door to the staff room was closed, and it was so quiet that no sign of human activity was felt.

Du Jiujiu gently called Wei Qingqing's name, but no one responded.

Seeing this, Du Jiujiu turned his steps slightly, and inadvertently blocked Hu Xiaoyun behind him.

"Qingqing, are you in there?" Du Jiujiu shouted again, and there was already a faint uneasiness in his voice.

Seeing that there was still no response, she put her hand on the doorknob and twisted it gently, but the handle did not move.

Du Jiujiu frowned, and his right hand touched the long knife behind his back, intending to break in.

At this moment, there was a sudden "click" at the door lock, followed by an old "squeak" sound, and the door was slammed open from the inside.

"Qingqing, is that you?"

Before Du Jiujiu's words fell, he felt a warm moisture gushing towards him like a tide, and Du Jiujiu protected Hu Xiaoyun behind him and quickly took a few steps back. After standing still, she looked into the room, and the place where she could see was a thick fog that seemed to condense into droplets, completely blocking her view from the environment inside the house.

The fog seemed to be alive, and after they pushed back, it slowly spread outward after the two of them.

Seeing this, Du Jiujiu instantly held the long knife behind him in his right hand and swung it forward. However, the thick fog was not dispersed by the strong wind brought by the long knife.

"There's something weird about this fog!" Du Jiujiu thought of Wei Qingqing, who was probably still in this room full of thick fog, and his heart suddenly cooled.

From the time she opened the door to now, there was not the slightest sound in the room, and it seemed that Qingqing might be more auspicious now.

"Jiujiu, Qingqing, she ......" Hu Xiaoyun also had the same idea as Du Jiujiu, and a pair of beautiful eyes were already shining with tears at this time.

"Sister Xiaoyun, don't worry, I'll go in and take a look." Du Jiujiu looked at the staff room again, the thick fog blocked the already dim light in the subway station, making this ordinary door look like a giant mouth from the abyss.

She gritted her teeth, clenched the long knife in her hand and rushed straight in, leaving Hu Xiaoyun's shout far behind.

As soon as he rushed in, Du Jiujiu felt that the fog was dense and foggy, and he was tightly surrounded by him. Walking in it, you can feel a faint resistance.

Du Jiujiu looked around, but there was still no light as if he saw it outside the house. She simply closed her eyes and only used her sense of hearing and touch to feel the movements around her.

Although the space of the staff room is not very large, it is a large room after moving out the clutter.

Du Jiujiu had also been here before, and originally they wanted to use it as a bedroom, after all, the space in the subway station is too wide to bring people a sense of security.

However, after considering that the air in this room was not mobile and inconvenient to use a campfire, they reluctantly gave up the idea.

But despite this, Du Jiujiu still knows the few furniture arrangements in this staff room.

Du Jiujiu moved slowly towards the position of the table and chair in the room in his memory, leaning his back against the wall.

After losing her vision, all other perceptions in her body seemed to be magnified several times at the same time.

In the dim environment around him, Du Jiujiu suddenly felt that a gaze stayed on him in the thick fog.

But just as she slowed down and felt the direction of the gaze, the gaze suddenly disappeared again, and the silence around her returned to death.

"Sure enough, there's something hiding here!" Du Jiujiu's heart moved slightly, but he didn't show too much abnormality.

The dark environment, unknown enemies, and Wei Qingqing, who doesn't know life and death, make her feel very tricky.

If it was just a simple enemy, Du Jiujiu even had several ways to force it out of the darkness.

But Wei Qingqing is still here at this time, and there may be a possibility of being alive. She must be careful with her actions, if she really hurts Wei Qingqing because of her carelessness, this is something she doesn't want to face no matter what.

Du Jiujiu moved his steps cautiously, guarding against attacks that might come at any time, and in a short time, the palm of the hand holding the long knife was already oozing with a slight sweat.

At this moment, an almost imperceptible breeze suddenly swept past Du Jiujiu's side. However, for Du Jiujiu, who was keenly aware of his five senses, this movement was as obvious as a stone falling on the surface of a calm lake.

In an instant, Du Jiujiu suddenly turned around, and the long knife slashed towards his side like thunder.

But the feeling of the blade cutting into it made Du Jiujiu's heart startled. The touch was not flesh and blood, neither gold nor stone, but more like a mass of some kind of liquid that had been gathered together.

When Du Jiujiu retracted the knife, his body also turned backwards, but his right hand was still stained with a little liquid splashed with the blade.

"Damn it!" Du Jiujiu hurriedly shook the cold liquid on her hand vigorously, after all, when she was attacked by the vines a few days ago, the pain caused to her by the vine venom stained on her body was still vivid.

However, to Du Jiujiu's surprise, there was a strange liquid splashing on the skin everywhere, except for a trace of coldness, there was no other discomfort.

Du Jiujiu raised his hand, brought it to his nose and sniffed it carefully, but he didn't smell anything.

"Is it water?!"

A thought flashed through Du Jiujiu's mind for a moment, but before she had time to sort out her thoughts, she felt as if something was approaching her behind her.

She turned and swung the long knife backwards in an instant, but before the blade could touch anything, a scream suddenly sounded not far in front of her, although it trembled a little from panic, but the crisp voice was so familiar.

With the girl's scream, the thick mist was also blown away by the strong wind at this moment, revealing a soft aqua blue, scattered in the air.

Under the long aqua blue hair, a small face turned extremely white under the reflection of the sword that exuded a chill.

"Qingqing!?" Du Jiujiu finally saw the figure in front of him clearly at this time, but the sharp blade that rushed away was about to cut one into two in the next moment.

"Why is this girl!?" Du Jiujiu was shocked and anxious, controlling the muscles of his body, and deflected the long knife a few points away, wiping Wei Qingqing's hair and narrowly slashing it.

Fortunately, Du Jiujiu had already realized in his subconscious just now, and this knife did not use all his strength, otherwise Wei Qingqing would have died on the spot this time.

------Off topic------

Thank you for your support. I feel a little too much for the few updates recently.,But I really can't spare time to calm down and code words.。

The feeling I had when I wrote it was blissful like I had never been, not to mention that this was my first book, and I would have finished it anyway, but as I wear many hats, I really can't afford to keep it updated every day.

The little squirrel bows to you here and says sorry, if this book is lucky enough to be loved by everyone, you can collect it first, and read it again after a while.

Thank you to all of you who still give me encouragement, and I will continue to work this road.
