We finally reached the passage on the fourth floor, and the soldiers here were still staring at the situation at the end of the passage, not daring to relax for a moment.

"What's going on here?" Su Lingxue was very concerned about the situation here and immediately inquired.

The officer next to him immediately came over to report: "Miss Su still kept the exit here at first, planning to lure the enemy out and ambush them. However, the gate at the end of the passage was also blocked just now, and now I don't know what is going on inside. ”

Su Lingxue nodded after listening to the report, and immediately asked the soldiers to retreat. "Okay, you guys stand back, and we'll take over here."

The soldiers were pulled up the stairs to defend themselves, after all, it was too much of a shame to have the flesh and blood of the soldiers against those monsters. But what should we do now, I was in the middle of a move when my phone rang suddenly.

"Call Xiaoyu, call Xiaoyu......" It's my uncle, come to contact me at this time, it seems that his time calculation is very accurate.

"Call uncle, call uncle, this is Xiaoyu, please reply." I hurriedly replied, don't let my uncle wait in a hurry.

"Xiao Yu, you have already entered the passage of the fourth layer." My uncle called me again.

I hurriedly reported the situation here to my uncle: "Yes, we have reached the fourth floor, and the door here has been sealed by steel plates, and we can't enter it now."

"Xiaoyu, do you have headphones, put them on, and keep in touch at any time. Put on your headphones and free your hands, the enemies inside are very cunning, you have to be careful everywhere. Without further ado, I immediately asked Gongyu Wushuang to open the door, go in and be careful, take care. "My uncle ended the call with me, and the door on the other side began to open.

I put on my headphones, put my phone in my pocket, pulled out my short sword, and after everything was ready, I turned around and looked at Su Lingxue.

"Sister Su, go in, I'll walk in front, and you will walk behind me." I originally wanted to carry forward my gentlemanly demeanor, but Su Lingxue didn't seem to appreciate it.

"No, let this little guy of mine go in and explore the way." As she spoke, Su Lingxue took out a thousand paper cranes from her sleeve, what is this for.

Su Lingxue whispered a few words to the little paper crane, and the little paper crane flew away lightly. The little crane didn't go anywhere else, but behind the iron gate.

Su Lingxue and I didn't speak, just stared at the darkness behind the iron door. I don't know what is hidden in the darkness, maybe it's a werewolf, maybe it's a monster, maybe it's something else.

After a few minutes, the little paper crane flew back to Su Lingxue's side again, and stopped on Su Lingxue's shoulder. The little paper crane was lying in Su Lingxue's ear and didn't know what to say, and Su Lingxue nodded straight there. I feel that this little paper crane must also be a woman, and only little girls like to whisper to each other.

I really couldn't help it, so I took the initiative to ask: "Sister Su, what's going on inside, you have to tell me."

"Okay, okay, I just asked the little paper crane to investigate and see if there is an enemy ambush inside." Su Lingxue said impatiently.

"How's that going?" Su Lingxue likes to hang people's appetites like my uncle, do they like this?

"The little paper crane said it was quiet inside, and there was nothing." Su Lingxue looked at me, but she looked at me in a daze. What does it mean to be quiet, and quiet is considered to have enemies or no enemies.

"Let's go, go in and see and you'll know everything." Su Lingxue had already started to walk towards the door, and I didn't want a girl to go alone, so I hurriedly followed.

It's dark inside, you can't see anything, if only you could see a little light. By the way, contact my uncle and let Gongyi Wushuang turn on the lights for me.

"Call uncle, call uncle, Xiaoyu call uncle."

"This is uncle, what is the matter with Xiaoyu."

"Uncle, turn on the lights, you can't see anything."

"Wait." There was no response after my uncle finished speaking.

Su Lingxue and I can't continue to move forward, and we don't know what kind of danger lies ahead. After a few minutes, bright spots began to appear in the interior, and it was the lights, and it seemed that my report was working.

"Let's go, let's go ahead." Su Lingxue didn't wait for these lights to turn on completely, and had already begun to move on. This woman is really bold, isn't she afraid of the monsters inside?

"Sister Su, in which room are those monsters locked up, let's see if those monsters have been released first."

"Okay, come with me." Su Lingxue didn't know what was wrong today, she always spoke coldly, and she didn't have her usual appearance at all.

Su Lingxue seemed to be very familiar with this place, although there were many rooms here and the passages were winding, Su Lingxue did not hesitate at all. Soon, Su Lingxue led me to a room with a hole in the door.

The door to this room is very sturdy at first glance, and there are two fences inside, one horizontal and one vertical. Next to this broken door is a heavy iron plate that has been demolished, and at first glance it looks like it was forcibly demolished by external force. The door frame next to it was also all broken, and it seems that this is the protective iron plate for the emergency start of the public transport matchless.

Now that the gate has been broken and the protective iron plate has been removed, it seems that the contents have escaped.

At this time, Su Lingxue still had to enter this room that had been destroyed, wouldn't it be superfluous.

"Sister Su, don't go in, let's go after the enemy, they shouldn't have fled too far." Although I tried my best to dissuade her, Su Lingxue didn't have any intention of listening to my nonsense. There's no way, I'd better go in and have a look.

Before I entered the room, I could already feel a chill. Not only that, but the entire interior of the room was surrounded by a white mist, making it completely impossible to see what was going on inside. How did this mist come about, it wouldn't be Wei Ran's trick again.

No, I can't let Su Lingxue in. "Sister Su, don't go in, there may be something wrong with this fog."

"It's okay, it's just an ordinary fog, nothing to do." Su Lingxue looked indifferent, it seems that she knows how this fog is formed, so I'd better quietly follow in.

Once I entered this room, I felt that biting cold, and this cold really made me feel uncomfortable. I saw that it was almost minus 40 degrees here, and I had to hug my shoulders to keep warm. But I see that Su Lingxue is still the same as no one, she is just wearing her usual summer clothes, is she really not afraid of the cold.

The fog was so thick that we couldn't see anything around us at all. But when I walked, I felt that the sound was very hollow, and it seemed that this room was too big. The white mist seemed to have begun to condense due to the low temperature, and a layer of rime began to condense on Su Lingxue's hair. Every time we take a step forward, the condensed rime falls like snow.

What the hell is going on here? Why is it so cold? Where did this white mist come from?

It all haunted me, but I couldn't find any answers. No, maybe I'll find out right away.
