The moment the passage above was sealed, I was suddenly shocked, and the first possibility that came to my mind was that someone had been following us and wanted to put us to death, but this idea was quickly denied by me, first, we had no enemies here, and second, there was no warning or motive at all.

I didn't have time to think about it, so I immediately took a few steps upward, hooked my head against the board above me with my shoulders, gritted my teeth and pushed it up.

This cover plate weighs a thousand pounds, and it is not something I can shake at all.

Yu Aiting's eyes widened in horror and said, "This ...... What's going on? ”

At first, I thought she was talking about the sudden closure of the passage by the top cover, and I was about to say that I didn't know, but I found that she didn't mean that, and I followed her gaze, and I saw that she looked at the candle in my hand and looked a little frightened, and leaned behind Uncle Liu again and again.

I looked down and saw that since I entered this underground passage, the light of the candle had somehow changed from yellow to blue and green, and the flame had become much smaller.

I was suddenly startled, and almost threw away the candle in my hand, Uncle Liu stretched out his hand to stop it, and said to me: "Although there is something strange, don't do stupid things, it is even more dangerous without light!" ”

I took a deep breath to calm down, looked at the cover above my head again, and suddenly remembered something, and asked, "If this is a sealed basement, the candlelight will definitely become smaller when there is not enough oxygen, but how can the color change so much?" ”

Yu Aiting seemed to think that my analysis made some sense, and said: "Insufficient oxygen, insufficient combustion of wax oil, which is often referred to in chemistry, may really change the color." ”

Uncle Liu shook his head and was about to refute, I suddenly realized that now is not the time for small talk, and I don't know where my father is now. So I preemptively said, "I'll keep these for later, let's go down quickly." ”

This corridor extends diagonally downward, and there are two faint points of light in the distance that are similar to the color of the candle light at this time, I thought it was a candle lit by my father below, and I tried to shout, the sound was unusually loud in the limited space, and after a while there was an echo, but there was no response from my father.

I became more and more uneasy, because judging by the speed of the echo, this corridor was very long, and it was only the time difference between us and my father when we entered this corridor, but he disappeared in such a short time, which was too strange.

The slope of the stairway was gentle, but even so, we walked slowly and cautiously with limited lighting, and the footsteps of the three of us made a rhythmic 'click' sound, and before we knew it, we found that the pace was so consistent.

The sound was like a hammer hitting my heart, and I felt very uncomfortable every step I took, and I thought it was because of the reaction of resonance or psychological effects, so I deliberately staggered my steps with them, and the consequences of disrupting the steps had some effect, and my heart was much more relaxed.

I walked and looked, only to see some potholes on the walls on both sides of the scratches, from the traces, every five scratches as a group, should be caused by humans, judging from the direction of the scratch force, it seems that someone is unwilling to be dragged down the stairs, desperately scratching the wall with his fingernails, trying to escape, some scratches seem to have dried blood.

My dad's sudden disappearance worries me very much, and I always wonder if this scratch was made by him, but I can see that there are countless scratches on the wall, and my heart is a little more stable, these marks must have been caused by many people, maybe my dad was not caught at all, but ran into it by himself.

After walking along the corridor for about six or seven minutes, I finally came to the end of the corridor, and the road in front of my feet was paved with flat stone slabs, and I don't know how long this place has existed, anyway, no one has been living in it for a long time, and there is a thick layer of dirt and ash on the floor, all of which fell from the top.

The place resembles a black box, boxy, with one end leading to the corridor behind the feet, the other to the unknown darkness, and the walls on either side.

The pair of blue and green beans flickered in the darkness not far away, much clearer than what had been seen before.

Inadvertently, I glanced back, and this look startled me, and I wondered, "What about the stairs?" Why is it gone?! ”

Uncle Liu and Yu Aiting also turned their heads to take a look, their expressions were the same as mine, it seemed that they were also frightened by this strange thing.

The staircase we came suddenly disappeared, and there was a wall behind it, which looked like it should be one with the walls on both sides, and I quickly ran over and touched it, and found that the wall was completely solid, and there could be no secret door or anything like that.

After all, Uncle Liu has enough experience in the rivers and lakes, signaled us not to panic, and pointed ahead to let us continue walking.

Suddenly, I felt a chill on the back of my neck, I felt a slight wind blowing, and I couldn't help but shiver, and at this time, the candle flame in my hand suddenly flickered and went out.

The three of us were plunged into endless darkness at once.

Uncle Liu took out a lighter and handed it to me, I pressed it with a 'snap', and a fire lit up, which suddenly went out before I could get to the candle.

This time I brought the candle closer, pressed it again, and suddenly a green tongue of fire half a foot high burst out of the lighter, and the Uncle Liu in front of me was as terrifying as a ghost, Yu Aiting screamed and grabbed my arm, my hand holding the candle was already bitten by fire ants, and it was very reluctant to take a candle.

I hurriedly put the candle in front of the lighter and lit it, but just lit the candle, Uncle Liu, whose face was green in front of him, smiled strangely, leaned over and blew on the candle, I suddenly felt a cold neck, it was as cold and biting as the gust of wind just now, and the candle went out again.

Even if I am stupid, I know what happened, but Yu Aiting didn't figure out the situation at all, she was a little angry and said: "Uncle Liu, how can you make such a joke, I'll be angry if I do this again!" ”

Suddenly there was a "uh...... Uh...... "Painful and hoarse ** sound, I know that this behind me is the real Uncle Liu, I don't bother to light a candle anymore, I reached out and touched the miner's lamp on my head, twisted the power supply, but the miner's lamp didn't react at all.

I turned around and touched the back, touched Uncle Liu's clothes, touched the clothes upwards, and suddenly touched his hands, only to feel that his hands were bruised, and he was pinching his neck. Before I could understand what was going on, I felt a tightness in my neck, and a hemp rope was put around my neck, and I was so frightened and frightened that I dropped the candle and the lighter, raised my hand and grabbed the rope around the neck of the sleeve, and tore it outward, so as not to break my neck alive.

In the boundless darkness, the three of us struggled hard, and the two blue-green points of light in front of us slowly approached us......
