This time, Suzak and I decided to go fast to see what was hidden at the end of the tunnel.

Unexpectedly, after walking a few steps, under the dim light, a gate covered with rust appeared in front of me, completely sealing the road ahead.

There was even a Japanese seal on the iron door that was almost corroded, which made me feel an indescribable excitement.

This iron door is almost the same as the mechanism door designed by the little devil before, and it also requires a key to open.

In addition, what made me feel particularly uncomfortable was the two seals that were crossed over the cracks of the door.

The Japanese on it looked like both Buddhist scriptures and runes for suppressing evil spirits, and suddenly there was an indescribable eerie and oppressive atmosphere in the tunnel.

But fortunately, Suchak, with some special ability that he had evolved, actually stuffed his finger into the huge keyhole of the iron door.

Immediately after that, the iron door with spring assistance inside opened a little by little, and the scene in front of us was instantly presented in front of the two of us.

When he stepped into the iron gate with a torch full of excitement, he couldn't help but feel a sense of loss in his heart, thinking that what was hidden behind the iron gate was the end of this strange tunnel.

Unexpectedly, behind the iron gate, there was only half of the wall where the excavation had stopped, and all kinds of ore crystals flickered in the soil.

It seems that decades ago, after receiving the order, the group of little devils will completely stop the excavation of the tunnel, and use such a heavy iron gate to completely seal the excavation opening.

It made me wonder if they really had to do this decades ago.

Looking at the ore flickering in the soil in front of me, I suddenly had an extremely frightened thought in my heart, and I was shocked into a cold sweat.

"These stones can't be some kind of radioactive ore, but if they are, they are dangerous ores."

According to the situation of decades ago, it is impossible for those little devils to bother to seal this place down, after all, they have already ordered a retreat, and it is really unnecessary to do so.

After tentatively digging the wall for a few minutes, I found that the soil here was still soft, and even if two people took turns digging it, it would not be too laborious.

Later, for a short period of time, he and Suchak have been digging the tunnel that the group of little devils gave up for unknown reasons decades ago.

For themselves, it no longer matters whether the ores hidden in the soil are really radioactive.

After all, after staying in the tunnel for so long, if something really goes wrong, it's too late to run.

Unexpectedly, the rock layer hidden in the soil became harder and harder the further back I went, and in the end, with only my left hand, I even had to lift the chisel and let Suchak rotate the hammer to dig little by little.

The sound of iron clashing echoed in my ears, and in an instant sparks flew everywhere, and after digging a few meters forward with great effort, I even faintly retreated in my heart.

I always felt that such a knock was not a solution, if the reason why the group of little devils stopped digging back then was only because there was a large area of hard rock hidden at the end of this tunnel.

Then it would be pointless for Suchak and I to do this, and even if we continued to dig, we would not find anything.

After sitting on the ground for a short rest, the wound on the severed arm of the right hand was accompanied by a burst of pain, which once again irritated the tired nerves.

I vaguely thought that this was the third level of the underground tunnel, and it seemed that it was also the last layer that had not been excavated, so could there be some hidden connection in the meantime?

While he was thinking, Suzak suddenly dug something out of the hard rock, and it was reflected in the light of the fire.

I was shocked to find out that it was actually a metal stationery box that was very popular a few years ago, and it seemed to be his daughter's belongings.

But this is obviously the deepest part of the tunnel, nearly a kilometer above the ground, how could such a modern thing appear.

The scene in front of him is simply indescribable by science, not to mention that this stationery box is still wrapped in a layer of rock, which has been excavated by Suchak with a chisel little by little.

This strange and inexplicable scene echoed in his heart, and Suchak in front of him immediately knelt down with a plop while holding the stationery box.

This is the second time he has found a clue about his daughter in the past six years, and I seem to be able to vaguely experience the incomprehensible taste in my heart.

"There must be something hidden under this Xiangxi mountain."

At this point, my heart became more and more determined, and I simply picked up the iron chisel with one hand and continued to join the team digging the tunnel.

Suchak looked at the stationery box and didn't speak, but his body almost fell to his knees, and his face was full of tears.

In the dim light, I heard him keep calling out his daughter's name, which was both heartbreaking and full of pity.

The distance between the opening of the iron gate has been extended by dozens of meters, and in addition to helping Suzak dig the tunnel, I pushed the wheelbarrow with one hand to carry some of the waste out of the hole.

As the two of them went deeper and deeper, I had an indescribable strange feeling, the sound of my heart beating in my chest, but I didn't know why.

I even began to wonder if I was suffering from a lack of oxygen, which was the most common symptom deep in this strange underground tunnel.

Suchak next to him woke up a little from his daughter's grief, and his hands rotated his tools to dig into the rock more powerfully.

Only I couldn't help but squat on the ground from time to time, breathing heavily.

Gradually, I felt my heart beat faster, and it seemed to have a lot to do with the location of the tunnel behind the iron gate.

It's as if there's something buried in the rock layer in front of you, which makes your body feel extra uncomfortable as you get closer.

Seeing that the waste rocks behind Suchak were about to pile up, and if they were not cleared out, it would affect the next pass, so I had to continue to push the wheelbarrow with my undulating chest, and transport the waste rocks out of the body door little by little.

I didn't have the idea of being decadent after my hand was broken, and even when I was pushing a one-handed cart, I wouldn't show mercy to myself, and I would still push the wheelbarrow with great difficulty.

The dim light was blurred, and the pressure on my body made the wounds all over my body ache faintly, but I didn't say anything, and kept gritting my teeth and persevering.

Suchak's physical strength seemed to never run out, and he kept swinging his hammer desperately, and the hard rock layer was shattered by his tools.

In just a few hours, a few more meters of tunnel was excavated, and I vaguely seemed to notice that the rock layer that had been shaken down was very different from the stone blocks on the surrounding walls.

This seems to be the effect of someone backfilling the rock with waste rock a few years ago, but to achieve the scene in front of us is enough to show that there must have been a naturally formed karst cave here a long time ago.

Watching the rocks gradually settle and baptize the traces, at least thousands of years away, made me a little hard to believe my own inference.

When the group of little devils dug here, they had exhausted a huge amount of manpower, and they and Suchak went all the way.

Just seeing the rotting corpses lying on the ground is probably more than hundreds.
