The staff room in the subway station was next to the bathroom on the other side of where they were. Although there was still a distance between them, they arrived at the door of the staff room in just a moment.

The door to the staff room was closed, and it was very quiet inside, so there was no sign of anyone moving.

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

Du Jiujiu turned around slightly when he saw this, and inadvertently blocked Hu Xiaoyun behind him.

"Qingqing, are you in there?" Du Jiujiu called again, with a hint of uneasiness in his voice.

Seeing that there was still no response, she put her hand on the door handle and twisted it gently, but the handle didn't move at all.

Du Jiujiu frowned and reached for the long knife behind his back with his right hand, planning to break in.

At this moment, a "click" sound suddenly came from the door lock, followed by an old "squeak" sound, and the door was suddenly pushed open from the inside.

"Qingqing, is that you?"

Before Du Jiujiu could finish her words, she felt a warm moisture spurting towards her like a tide. Du Jiujiu protected Hu Xiaoyun behind him and quickly took a few steps back. After standing still, he looked into the room and saw what he saw.

It was filled with thick fog that seemed to condense into water droplets, completely blocking her sight from the environment inside the house.

This thick fog seemed to be alive. After they pushed back, it followed the two of them and slowly spread outward.

When Du Jiujiu saw this, he instantly grasped the long knife behind his right hand and swung it forward. However, the thick fog was not blown away by the strong wind brought by the long knife.

"This fog is weird!" Du Jiujiu felt a chill in her heart as she thought about Wei Qingqing who was probably still in this room filled with thick fog.

From the time she opened the door until now, there has been no sound in the room. It seems that Qingqing may be in danger now.

"Jiujiu, Qingqing..." Hu Xiaoyun also had the same thoughts as Du Jiujiu, with tears shining in her beautiful eyes.

"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 dim light in the subway station, making this ordinary door look like a

A maw from the abyss.

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

As soon as she rushed in, Du Jiujiu felt that the fog was as dense as a substance, tightly surrounding her. When walking in it, she could actually feel a weak resistance.

Du Jiujiu looked around, but there was still no light as seen outside the house. She simply closed her eyes and only used hearing and touch to feel the strange movements around her.

Although the space of the staff room is not very large, after moving out the sundries inside, it can be regarded as a quite small room.

Du Jiujiu had been here before. Originally, they wanted to use it as a bedroom. After all, the too wide space in the subway station did not easily give people a sense of security.

However, after they considered that the air flow in this room was poor and it was inconvenient to use a campfire for lighting, they reluctantly gave up the idea.

But despite this, Du Jiujiu still knew the layout of the few furniture in this staff room.

Du Jiujiu moved slowly towards the position of the tables and chairs in the room in her memory, leaning against the wall.

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

In the dim environment around her, Du Jiujiu suddenly felt a gaze resting on her in the thick fog.

But just when she slowed down and carefully felt the direction of the line of sight, the line of sight suddenly disappeared, and the surroundings returned to a deathly silence.

"Sure enough, there is something hidden here!" Du Jiujiu's heart moved slightly, but she didn't show much strangeness.

The dark environment, unknown enemies, and Wei Qingqing who didn't know life or death made her feel very troubled.

If it were a simple enemy, Du Jiujiu would even have several ways to force it out of the darkness.

But Wei Qingqing is still here at this time, and there may be a chance of living. She must be careful with her actions. If Wei Qingqing is really hurt because of her carelessness, this is something she does not want to face anyway.

Du Jiujiu moved her steps carefully while guarding against attacks that might come at any time. Soon, a slight sweat began to form on the palm of her hand holding the long knife.

At this moment, an almost imperceptible breeze suddenly passed by Du Jiujiu's side. However, to Du Jiujiu, who had keen senses, this movement was like a stone falling on a calm lake.

It's obvious.

In an instant, Du Jiujiu suddenly turned around and slashed towards the side of his body with the long knife like lightning.

But the feeling of the blade cutting in made Du Jiujiu startled. The feeling was not flesh and blood, nor gold nor stone, but more like a lump of some kind of liquid that had been gathered together.

When Du Jiujiu put away the knife, she also turned her body sideways, but her right hand was still stained with a little liquid splashed by the blade.

"Damn it!" Du Jiujiu quickly shook the cold liquid on her hand hard. After all, when she was attacked by vines a few days ago, the pain caused by the vine poison on her body was still vivid in her mind.

However, to Du Jiujiu's expectation, there was a strange liquid splashing on the skin. Apart from a hint of coldness, there was no other discomfort.

Du Jiujiu raised her hand, brought it close to her nose and sniffed it carefully, but she didn't smell anything.

"Is it water?!"

An idea flashed through Du Jiujiu's mind for a moment, but before she had time to organize her thoughts, she felt that something seemed to be approaching her from behind.

She turned around in an instant and swung the long knife back. However, before the blade touched anything, a scream suddenly sounded not far in front of her. Although she was trembling because of panic, the clear voice was

So familiar.

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

Under the long aqua hair, a small face turned extremely pale under the light of the sword that exuded bursts of 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 of them into two in the next moment.

"Why is it this girl!?" Du Jiujiu was frightened and anxious. Controlling all the muscles in his body, he deflected the long knife a little and narrowly missed Wei Qingqing's hair.
