After saying that, I directly bit the pearl with my teeth and ripped it off the earring, Kiko stopped doing it at that time, slapped me on the head and said angrily: "Yu Miao! What the hell are you going to do! My earrings are very expensive! ”

"How much can an earring cost? I'll buy it for you when it's out! I casually asked and put the pearl on the ground, and I saw that the smooth pearl had stayed on the seemingly flat ground for a moment, and then rolled towards us!

"Huh? How so? Kiko's face was full of surprise, but I secretly said in my heart, sure enough, in fact, I felt something was wrong a long time ago, obviously it looks like a very flat ground, but walking on it has a feeling of climbing a mountain.

However, this ancient building is built on a hillside, and it is a wooden structure, so it will inevitably expand and deform as it grows older, so I didn't pay too much attention to it, but when Kiko said that this corridor was ridiculously long, I almost immediately thought of the strangeness of the ground, and after trying again, it was exactly the same as I had guessed!

"Actually, the ground here is not flat, but has a slight upward slope, and the slope is different after each turn, so it is difficult for us to notice when we are not paying attention." I casually explained as I looked around.

Kiko also showed a sudden realization after hearing this, and after a pause, he asked suspiciously, "But why do you want to set up this kind of thing?" Doesn't that seem like a useful thing? ”

I smiled and didn't speak, because I also felt that this kind of setting was useless at all, but the Liu family spent a lot of manpower and material resources to build here, and it was impossible to do such superfluous things, so this corridor must have its own meaning, but we haven't discovered it yet.

I looked around and didn't find it, so I beckoned Kiko to move on, the metal rail on the ground was shining in the light of the flashlight, so I wasn't afraid of getting lost, so I just followed the rail back again!

After walking for less than ten minutes, we were forced to stop again, this time not because we had found anything unusual, but because there was no way ahead.

A thick brick wall cuts off the entire corridor, and the metal guide rail doesn't go straight into the wall, and anyone with a discerning eye knows that there must be a secret door or something like this, but Kiko and I don't know anything about it, and we still don't have a clue after studying it for a long time.

As time passed, my mood also became anxious, and then I couldn't wait to tear down this wall directly, but first, I don't know if the demolition of the wall will cause any bad changes, and second, the wall is as thick as something, with my little strength, I estimate that I will be exhausted halfway through the demolition, so in the end I still didn't take action.

The two of us sat down side by side against the wall, and Kiko whispered as she swept around with a flashlight, "I think this secret door is like a light switch, it will definitely be set up around the secret door, why don't we find out if there is anything unusual here, or something that shouldn't belong here......"

Before Kiko could finish speaking, we both saw a lamp on the left hand wall at the same time, and there was nothing strange about the lamp itself, except that there was a lighter in the small dish that held the lamp oil.

We looked at each other: "This is it!" ”

Standing up, I first took the lighter in my hand and checked it, nothing special, just a dollar plastic lighter everywhere, since there is no problem with this thing, then the problem should be with that lamp.

I remembered the scene I saw on TV before, I grabbed the lamp and pulled it down hard, and found that I couldn't pull it and changed my strategy to push it up, pulling left and right, and even pushing it twice into the wall, but the lamp never moved at all, Kiko took a closer look and said, "Don't bother, this thing is embedded in the wall, it shouldn't move." "Wonderful Pen Pavilion

Hearing this, I couldn't help but be deflated, smacked my lips and let go of my hand, and suddenly found that there were a lot of slimy things on my hands, and when I looked at it, it turned out to be some grease, probably when I held the lamp just now, I accidentally got it in the small dish containing the lamp oil.

I wiped my clothes twice, and I was about to continue studying the lamps when I suddenly had an idea—the oil lamp on the wall, the slightly melted lamp oil, the lighter...... That's a hint that's too obvious!

"What the hell am I an idiot!" I sneered, raised my hand and slapped myself in the mouth, Kiko looked at the side with a blank expression: "Why are you hitting yourself?" Sick? ”

I shook my head and didn't say anything, I raised the lighter and pressed the flame and walked towards the lamp, the lamp oil in the small dish did not know what the material was, after so many years, it did not deteriorate, I used the lighter to bake for a while The lamp oil began to melt, and then a wick inside began to light up a bean-sized flame.

Kiko still didn't know what I was doing, so she shook her flashlight and asked suspiciously, "What?" Don't you think it's bright enough? ”

"No," I shook my head, keeping my eyes fixed on the flame on the lamp: "This lighter was left by someone before, and it must have a special purpose when it was placed on the lamp, and the oil lamp and the lighter were put together, what was the first thing that came to your mind?" ”

"Light up!"

Kiko blurted out without thinking, and as soon as the words fell, suddenly a muffled sound of "bang-la-la" came from the wall, which sounded like the sound of an iron chain dragging on the ground, and after a few seconds, the sound stopped, and several bricks next to each other on the wall blocking the road slowly retracted into the wall, revealing a fist-sized dark hole.

"It's done!"

Kiko and I looked at each other and smiled and hurried to the entrance of the cave, the entrance of this size is definitely not for us to pass, I thought for a moment and was about to put my hand into the hole to find out if there was a mechanism, Kiko suddenly grabbed me and whispered: "What's the hurry!" What if there's danger inside? ”

"Do you have a better idea?" I raised an eyebrow at Kiko, who turned on the flashlight and shone it into the dark hole.

"Uh......" I couldn't help but feel embarrassed, and said that I was really in a hurry, and laughed twice and gathered with her to observe the hole.

This hole doesn't lead directly behind the wall, but the part we can see is nearly half a meter deep, and I can't help but be glad that I didn't choose to tear down the wall just now, otherwise I would have been exhausted after half of it!

There is an iron ball in the deepest part of the hole, the size is about the same as the iron gall that some old men like to play, and the iron ball is connected to a steel bar behind the wall inserted into the wall, looking at this setting, it should be for people to reach in and hold the iron ball, and then pull out or push in to open the secret door.

I was about to stretch out my hand, but Kiko stopped me, and before I could speak, she deflected the angle of the flashlight, and I saw that there was a groove two or three centimeters away from the hole, and when the flashlight shook, I could vaguely see the cold light of metal reflected in the groove......
