The ethereal sound from the building shocked everyone. Although I was used to this natural phenomenon, I still felt a little scared. However, I was still the calmest, as for the others...

"Lin...Brother Lin, was the sound just now..." Wen Cao was so scared that he shivered, hiding behind Wang Tuming, and grabbed the corner of the latter's clothes with both hands.

"Calm down, there is no abnormality in the spirit measuring device." I raised my phone and walked to the door first. "What's more, how can there be ghosts in the world?" I held my phone and looked at the door.

The door of the building is made of iron, and it has been rusted after so many years. There is also an old-fashioned iron lock on the ground, which is covered. It is probably someone's masterpiece when he pried the door in the morning. I reached out and was about to push the door, but the cold air from the crack in the door made me subconsciously shrink my hand back. I frowned and turned around and asked the lady, "What's the temperature inside when you go in in the morning?"

Xing Xiaolou replied, "The temperature is not much lower than the outside, about twenty-seven degrees Celsius." She saw something wrong with my expression, and suddenly realized something "You don't want to tell me..."

"You guessed it." My face was solemn, "Now, the temperature inside is definitely several degrees below zero..." In order to prove this, I simply pushed open the iron door, and the iron door slowly opened, making a strange creaking sound. At the same time, the cold air inside rushed towards everyone, and the door was pitch black, like an abyss that could not be seen, which made people easily believe that the other end was not an office but a hell in the underworld.

"It's so choking... I think we'd better go back..." Duan Dan was the first to give up.

"Coward!" Huang Xiaodong looked at him with contempt and said, "You are tall and big, why are you even timid than Wen Cao?"

"Hey!" Wen Cao was shot inexplicably and shouted, "What do you mean to be timid than me? How come I am timid!"

I turned around, shone the light of my phone on my face, and whispered, "I said you guys... I'm not responsible for speaking so loudly that something strange is alarmed..."

Hearing this, the three of them quarreled obediently closed their mouths.

I stood at the door, the light swept the scene inside the door, and continued, "Then... Next, I will walk ahead and Chen Zishao cut off the back. Please be careful."

The first floor is not large and the facilities are simple. Three Changsha and one wooden table (of course, it has become coke now). This should be the place for teachers to rest. The surrounding walls are burnt black, some of the walls are cracked, and the bricks and tiles inside are exposed. Dust is filled with the air, and we have to cover our mouths and noses with our hands to prevent dust from inhaling. It seems that the mark of the fire back then did not dissipate with the passage of time. When we entered the door, we seemed to be in the fire again.

"Let's search the first floor first to see if we can see what can be found." I said.

"That's right..." Xing Xiaolou took the conversation and said, "I have confirmed it in the morning. There are no clues on the first floor..."

"Of course I know this," I paused, "I do this for two things. One is that there are differences between natural phenomena and night. Two, you searched for it during the day, not me."

"Tsk..." Xing Xiaolou looked at me with disdain and did not continue to linger on this topic. "So, my big detective, I'm the only two of you here have flashlights, how can we search?"

I turned my head and looked at the lady with an idiot expression, "Are you stupid? You can just divide it into two groups. You and Wang Tuming and I search downstairs, and the others followed Chen Zishao to the upstairs and started work!"

So, after ten minutes, the three of us carefully searched the entire first floor and sorted out several clues...

1. In some floor cracks, tiny purple-black vines grew, similar to those that killed Qiu Ming.

2. There are signs of fighting.

3. In a very hidden corner on the first floor, a hole covered by bricks and tiles appeared.

Seeing this bottomless cave entrance, Wang Tuming complained, "Is it because the political and educational department teachers back then were actually a group of underground workers? Do you think this is their secret base?"

"This possibility is not ruled out..." I stared at the dead fish's eyes, "Why would I kick you down and take a look?"

"I'll go and see how they are." Wang Tuming turned around and left. But he seemed to have forgotten the fact that there was no flashlight, so he fell several times with bumps and bumps...

Xing Xiaolou couldn't help but smile and said, "Your classmates are quite interesting."

"Everyone, your good friend is also quite interesting, isn't it?" I squatted by the entrance of the cave, my eyes were like a torch, and my thoughts were not on Xiaolou at all. When I realized that someone's secret was accidentally revealed, I was slightly shocked. However, Xiaolou's next words surprised me even more...

"It seems that you have also found her identity."

I stood up and looked at her blankly, "You have appeared long ago, right?"

Xing Xiaolou smiled and said, "I'm not a fool. You can see a clue after only a few minutes of meeting her, let alone I've known her for so long."

Indeed, Xing Xiaolou is not stupid, but on the contrary, she is very smart. She lacks cognition in supernatural events, so her mind is so muddy. Moreover, although the girl is a lady from a famous killer family, to be honest, it is really not very good to disguise and anti-detection. It is not uncommon for Xing Xiaolou to be revealed...

"Although I don't know what Gu Xiaoxiao's purpose is to approach me, I can see that she did not deceive me in terms of feelings. She did not show any strange actions." Xing Xiaolou said again, "So, I turned a blind eye."

Of course she won't, because her purpose is to get close to you is to have a taboo love with you... Of course, I only dare to say this in my heart.

"Okay, let's not talk about this. What do you think about this cave?" Xing Xiaolou asked.
