I glanced behind me. Behind me was a stone wall, and I couldn't see any way in.
"Strange, where am I?"
I shouted behind me, calling Zhang Ji's name.
"I'm here."
His voice came to me faintly through the stone wall.
"Don't move there, wait for me."
I immediately turned around and quickly touched this stone wall.
The next second, my body was empty and I fell to the other side.
I happened to fall under someone's feet, and Zhang Jizheng looked at me in astonishment.
"How did you do it? Suddenly disappeared and then suddenly appeared again?"
I shook my head and pointed to the wall behind me.
"This place is empty. There are no real walls. You can walk through it from here."
After saying that, I picked up Zhang Ji and quickly walked through the stone wall and came to the other side again.
Zhang Ji looked at me in disbelief, stretched out his hand to touch the stone wall, and quickly passed through it.
"Oh my God, what is this? Why does it look like there is a wall here, but this place is empty?"
I shook my head at the surrounding walls.
"I think there is a high probability that the person who set up this place created an illusion for us through light or other reasons."
After that, I walked around the wall.
I soon found a prism on the ground.
When I took this thing away, mottled ripples appeared on the wall in front of me, and there seemed to be a gap in the wall.
Zhang Ji was even more unbelievable and couldn't help but touch her mouth for half a minute.
"Oh my god, can this be achieved?"
I nodded, then pointed to the hole in the wall and said to him.
"Look here, this place has dust floating vaguely upwards from around the walls on both sides. I think these things are very similar to projectors. They used the dust as a screen to project the projections of some of the walls onto it, intervening It should be the prism in my hand."
I picked up the prism. It was polished with special jade. The surface was extremely smooth and could refract and reflect like a real mirror.
I looked around at the empty caves.
"And I feel that there is definitely more than just such a mechanism here. There must be other mechanisms hiding in the dark, waiting for our discovery."
I held the prism in my hand and put it in my backpack.
"Let's go first. We don't have time to continue searching here. At least we have left a gap here. When we can't find the road, we can turn back and find this place."
Zhang Jicheng nodded to me, immediately followed my footsteps and walked forward.
I knocked on the stone wall, and Wang Wangyang and the others above began to move forward again.
I followed immediately.
The situation here is exactly the same as before. The sound of footsteps keeps ringing from under our feet, helping us guide the way forward.
But soon, the footsteps stopped.
Immediately afterwards, there was a faint call from under my feet.
I immediately lay down on the ground and listened carefully to the sounds below.
"We have reached the end. There is no way. I can't continue to guide you."
They don't know what happened here yet.
Presumably they have experienced the same situation as us. It seems that they have reached a dead end, but in fact there is another way to survive.
After I decided to follow them, I took out the nails from the wall. Now I took out the nails again, simply nailed them to the wall and continued to climb down.
When I reached the top wall again, I immediately raised my voice and told them carefully what we had just discovered against the wall.
Soon, the surprised sounds of the two of them came from under our feet.
"In other words, there is a way out of the wall around us, right?"
I nodded, quickly took out a nail, and pointed it at the ceiling in front of us.
"Just wait, I'll throw a nail to you, listen to the sound to identify the road, and see if you can find the corresponding exit."
I aimed the nail at the ceiling in front of me and smashed down on that piece.
Bang.
There was a loud bang from the ceiling.
Obviously, the two people above seemed to have heard the noise we made.
They immediately replied in a panic.
"We understand. There was an obvious sound just behind one of our walls. Is it from this direction?"
Immediately afterwards, the two of them lost their voice.
But I clearly heard their footsteps moving forward, and soon they were going down the original passage.
I suddenly understood everything here.
To be precise, if a person enters this place, he can only wait to die.
If there are two people who are just divided into upper and lower floors, they can use each other's footsteps and voices to pass through this passage.
And you can only use the walls and floors to communicate.
The deception here is too strong. If ordinary people cannot discover the secrets here, they will be trapped and die directly under the ground.
There is no way to survive at all.
I jumped off the wall, took off the nail, and immediately followed the footsteps.
Zhang Ji also quickly followed.
The two of us continued to follow the footsteps above and walked forward along the passage.
This is a passage we have never been to before, and when we look up through the passage, we can clearly see footprints and handprints on the ceiling.
"It seems that we are still in danger."
I finally knew why these footprints and handprints suddenly disappeared.
There is a high probability that it has entered these spaces that we cannot see at all, and then this ghost thing is hiding here.
And now, I have no idea in which corner the guy above our heads is hiding, waiting for an opportunity.
"Zhang Ji, no matter what, you have to be careful, and you must be careful of the tops of our heads."
I told Zhang Ji and continued to move forward cautiously.
The current situation is very special and we must not take it lightly.
Zhang Ji nodded to me, followed me cautiously, and walked forward silently.
The two of us quickened our pace, following the guidance voice above as much as possible, and quickly passed through the dark tunnels.
Finally, a little light appeared in front of us.
My heart was shocked, and I quickly pulled Zhang Ji beside me.
"Be careful, let's go slowly. There's a problem ahead."
After hearing my words, he nodded to me, immediately took out the dagger from his body, placed it across his chest, and followed me cautiously.
I looked at this space carefully.
There were actually four round fist-sized beads placed around it. These beads actually gave off a little dark light under the ground.
The green light lit up the entire space, as if entering the underworld.
"Light-in-the-dark ball?"
Zhang Ji hit the nail on the head.
This thing does look like a luminous ball, but deep underground, this place should have a history of thousands of years.
Since there is no light, these luminous balls cannot shine as well as they do now.
Unless there is another light source here.
I moved here cautiously. The light from the luminous ball was not strong and could only vaguely illuminate a few corners around him.
But the center of the room has become a blind spot that cannot be illuminated by light.
I raised my flashlight and pointed it at the center.
The place was empty, with no trace of ghosts or human figures.
I breathed a sigh of relief and called Zhang Ji beside me, asking him to follow me closely and not to fall behind.
At the same time, I raised my flashlight and pointed it at one of the luminous balls.
And at this moment, the light of this luminous ball suddenly became a little brighter, quickly lighting up everything around us.
"Is this thing so capable of absorbing light?"
If this is the case, then I can most likely imagine why there is such dim light under the ground.
Maybe before us, maybe more than ten or decades ago, there were people here.
They shined light through these luminous balls, and the light slowly emitted outwards until they are preserved to this day.
if it is like this.
I immediately turned the direction of the flashlight and shined it towards those light balls.
Soon, these light balls bloomed with a green light that was more obvious than my flashlight, illuminating the entire room with a green light.
The light here is extremely strong, which can already help us see clearly the condition of the entire space.
At this time, I vaguely heard footsteps coming from above.
But under our feet, there was no longer the weird sound just now.
"Can you hear me? Wang Wangyang, Cui Hao."
I pressed against the stone wall and shouted upwards.
Soon, I clearly heard a response from above.
"Okay, we are above your heads now, right? We have arrived at a tomb-like place with four coffins."
I was stunned for a moment, and I quickly asked the two of them.
"Aren't the four coffins four luminous pearls? What's going on there?"
There was a bit of confusion in the voices of the two people.
"There are no luminous pearls. It's so dark here that you can't see anything. There are only four coffins. We can only see clearly when we shine our flashlights. Are there four luminous pearls there? It's amazing, right? ?”
I immediately interrupted Cui Hao's complaint and responded hastily.
"Don't be envious. I think there is a problem here. Where are the four coffins of you?"
Wang Wangyang's voice immediately sounded.
"It's just in the four corners of the house down there. Is there anything wrong with that?"
The panic in my heart was even worse.
"The four luminous pearls below us are also distributed in the four corners of the house. Do you know what this means?"
Their voices immediately became tense.
"The top and bottom correspond to each other, just like before!"
