After understanding that this might be the mark left by Zhang Tianxing, I hurriedly followed the rock wall and continued to look for it.

Since the spacing between the marks is a bit large, and it is pointing downward, looking at this posture, the third grimace should be out of reach of my feet, doesn't this require me to jump down to see it?

Engrave the mark in a place that can't be reached at all, the mark itself loses its meaning, I think Zhang Tianxing should not be so lacking in heart, since he engraved the mark in this place, it won't be carved for fun, right?

Thinking about it, I directly lay down, stretched out my hand, and after some groping, I soon found the clue, under the stone road, it turned out to be empty.

The stone path is broken here, and there are unexcavated rocks below, since there is an unexcavated stone wall below, how can it be empty? The only explanation can only be that when the stone tunnel was excavated, the person who carried out the work found that the bottom was empty, and since it was empty, it must not be possible to continue to excavate down, so the stone tunnel was stopped when it reached this point.

The excavation of the stone passage has been carried out in such a huge way, and a quarter of the work has been completed, and it is certainly not possible for those who carried out the work to give up the work to the end because the bottom is empty, and there must be other ways to get to the bottom.

I'm not sure where the rest of the road will be, so I can only hope that these people will be lazy and drive the way down nearby, otherwise I'll be out of luck.

I followed the grimace mark and touched the empty stone below the stone path for a while, and soon I felt the third grimace notch, and although I couldn't see it, I couldn't have made a mistake about the familiar outline. Before I could recover from the joy of discovering the third mark, my hand immediately felt a chain the thickness of a cigarette pipe on the side of the third mark.

I tried to flick the chain, but it didn't shake at all, and it seemed to be quite strong.

This is good news, and I am almost certain that this is the way to the bottom of the pit designed by the same people who did the stone excavation work. Looking is looking for it, but the key is how to go down?

The stone platform under my feet was more than fifty centimeters thick, and the iron chain was under the stone platform, so I couldn't see it with my eyes, and I could only touch it by lying on the stone path and reaching down. It was quite difficult to get down to the chain from above, and I had to reach down with one hand and grab the chain, and then my whole body left the stone path above me and grabbed at the chain in an instant.

This is not an easy task, or it is not an easy thing to say, if the Taoist priest is here, it must be very easy to go down with his skills, but I am different, I have never practiced martial arts, and my arm strength is not strong, it is quite difficult to support the inertia generated by the moment the whole body falls with one arm, and I will be thrown out of my whole person, more than 30 meters high, and it is completely equivalent to a death sentence.

I took a deep breath, the curse growing stronger, and I knew I had no time left but to gamble. Thinking of this, I gritted my teeth, said the blessing of the Buddha, grabbed a ring of the iron chain below with my right hand, and then moved my body, and the whole person was planted.

At the moment when my body fell, the right hand holding the chain suddenly received a strong pull, and then the downward trend became the inertia of throwing out, and my body was immediately thrown out to one end of the chain.

This is the most critical few seconds, as long as I get through, my left hand will immediately grasp the chain, and the whole person will be able to climb onto the huge chain. I almost gritted my teeth, and I even heard a click from my shoulder bone, which was the sound of a dislocated bone.

Fortunately, I held on, and the body that was thrown out was quickly pulled back by my arms, and I hurriedly hugged the chain with my left hand, and my two feet were also desperately wrapped around the chain, until my body was completely used to this feeling, I was barely relieved.

The chains are very thick, with a large space in the middle of each loop to grasp and a foot to step between them, which is equivalent to a small ladder.

After the most thrilling scene, my spirit quickly recovered, my right hand because of the huge inertia just pulled, the shoulder bone should have been dislocated, just now it was completely with a tenacious perseverance to persevere, at this time the danger was lifted, the spirit relaxed, the huge pain immediately swept over, and the hand could not be used.

I sighed, and now I can't deal with it on the chain, so I can only wait to go down to the bottom of the pit to deal with it.

It was only then that I had time to take a look around me. I looked around and saw that there was indeed nothing under the stone path, not only empty, but also an immensely large space.

Originally, I thought that the sinkhole was already very wide, but I didn't expect that there was such a big place near the bottom of the sinkhole, which can no longer be described as a cave, because no matter how huge the cave is, it cannot be as huge as what I see now, this is completely another independent world!

At this time, I was attached to the iron chain, more than 30 meters above the ground, such a height is already very unusual, but at such a height, I still can't overlook the edge of the space below, the black pressed trees are endless, stretching into the distance, as if the space below has been completely hollowed out, becoming another world.

It was so horrible that I couldn't believe the look in my eyes, and I even forgot that I was still in a chain, in danger of falling to my death.

It took me a long time before I came back to my senses from the shock, and the impact of the underground forest in front of me was no less than that of the underground ruins in Fengyang.

"My dear, what the hell is this place?" I muttered to myself, subconsciously clamped my legs, stabilized my body, and grabbed the camera. This location is the ideal location to photograph the underground forest in front of you, and from such a height and angle, you can perfectly interpret the most shocking side of this underground world.

I took several shots in a row, until my feet couldn't hold the chains, and I stopped, and the scene in front of me was so beautiful and shocking that I didn't want to go down a little.

Naturally, I couldn't stay in a chain forever, even if my willpower allowed it, and my body wouldn't allow it. The constant tossing and turning along the way had exhausted most of my physical strength, and I had to go down to the bottom of the pit before I ran out completely.

Thinking, I started to climb down.

Because I was missing a hand, my speed was very slow, in fact, the original builder did not only build an iron chain, but there were actually three identical iron cables around me, which ran through the rock above, and there was no situation below, but it was probably fixed in the rock. Between the four chains, there was originally a lift car operated by a set of pulleys, but due to its age, the iron car had decayed to the point that only one frame remained.

Half an hour later, I finally went down to the bottom of the pit, and a large rock hanging in my heart finally fell to the ground.
