Huayu deduced that there might be a passage next to the cave we just entered that was exactly the same as here, but we happened to open it the other way.

I said, "Possibly, it seems that we still stumbled into it by mistake, since we are here, let's look for it." ”

Hua Yu and I divided up and began to search for the situation of this underground cavern.

Although it was very dark underground, and we could only use two flashlights, we still found something different.

Next to these holes shaped like spider's feet, I found a large number of footprints, some old and new, some from a long time ago, all in a row, and next to these rows of footprints, there were some sparse footprints.

Hua Yu found the same footprints on the other side, and we felt strange, so we had to stay together again to discuss how these footprints came from.

I squatted next to a footprint and said: "Look at these footprints, the footprints in the rows are very flat, they should be flat-soled shoes, and these footprints are of different depths, indicating that the body size is fat and thin, according to the analysis of this kind of footprints, there should be people here often, but the latest footprints here are almost a month, could it be that this cave has been abandoned?" ”

Hua Yu shook his head and said to me: "No way, you look at the dryness of this cave, it definitely doesn't look like it is deserted, most of these people who have gone into the depths of the underground are doing something, you see that next to these footprints, it looks like shoes that don't look like the combat boots supplied by Marsgar's army." ”

I looked up, and sure enough, like the soles of my boots, it looked like there might be more secrets in the depths of this cave.

With a solemn expression, I looked at the footprints on the ground and said slowly, "You said that the owners of these footprints could not be the dead people we found earlier." ”

Hua Yu could not deny it: "There is a possibility, if according to what you say, it is very likely that there is some kind of prison room underground, in which a large number of civilians are imprisoned, and at first Samochi attracts these people with a high remuneration, and then he is secretly brought here in order to fulfill the plan in his heart." ”

I looked at the hole where the footprints pointed, there were eight holes, not every one of them had footprints, and the rest of the holes had very few footprints, and the shoe prints were of different patterns.

Hua Yu collected the footprints on the ground and passed them to Shu Xiaomi, and said to Shu Xiaomi: "Xiaomi, you should go and check the missing people in Marsgar over the years, and count how many people have disappeared since Samochi came back from the army." ”

Shu Xiaomi didn't dare to be careless at the moment after dozing off just now, and hurriedly asked, "Then what should you do?" ”

I said to Shu Xiaomi: "We are going to go deep underground now to have a look, we won't come out for the time being, if the people from Thunderbolt ask, you will say that we are going on a trip." ”

"Okay, then you pay attention to safety, and call me at any time if anything." After Shu Xiaomi finished speaking, she hung up the one-line contact.

I took a look at the bottomless black hole in front of me again, beckoning the rain to go deeper into the cave.

The road we entered seemed to have no end, and before entering, I had considered going to the other caves first.

But the terrain is unfamiliar, I haven't even figured out the most basic situation, and I don't dare to walk around casually for the time being, although there may be some things hidden in other caves, but these will still have to wait until we figure out what this underground cave is used for before we can draw conclusions.

We kept going down the depths of the passage, and we couldn't see the way we came, but to our strange thing, the further down we went, the warmer the cave became.

By the end, I felt like I was roasting in the sun, and I was sweating all over my body.

After walking for more than ten minutes, my flashlight seemed to hit something, but the distance was still too far, and it was difficult for the flashlight to illuminate the things in front of me clearly for a while.

When I got about 50 meters in front of me, I saw that there was a door in front of me.

"Why is there a door here?" Hua Yu said and walked to this door to take a closer look.

In front of us was an iron door, I touched this door with my hand, because of the high temperature, the temperature of this door is also extremely high, if you leave it for a long time, it will be hot.

There wasn't any doorknob or anything like that on the door, so I said to Huayu, "It looks like this door is open from the inside." ”

This made me and Huayu a little embarrassed, and after walking for so long, I actually ran into a door that opened from the inside, didn't this trip go in vain?

Hua Yu listened sideways to the situation inside the door, and after a while, he said to me, "It's quiet inside, it looks like no one is there." ”

We didn't know what was going on inside, so we didn't dare to jump to conclusions, so we had to look around the walls to see if there were any keys or anything like that could open the door.

The perimeter of the passage was not complicated, and we soon found something wrapped in an iron box.

This iron box is embedded in the wall, only one side is facing the outside, it is very strong, I pulled it with my hand, and there was no reaction at all, as if it had been growing in this wall all along.

I turned on the switch of the box, shone it with a flashlight, and saw a black round button at the bottom of the box.

I pointed to the black button and said, "Could this be the switch that opens this door?" ”

Hua Yu didn't know much about this kind of switch, shook his head and said, "Looking at the situation around here, there is nothing special, maybe this is the key to open this door." ”

It's hard to know for sure if it's not, and if the button isn't the key to open the door, then it's probably a mechanism.

Whether there is danger under this button, I am not sure at all.

But now we have no other way, if we don't press it, then we can only go back the way we came and find a way out again.

I didn't press it in a hurry, but said to Huayu: "If this button is pressed, there is no guarantee of any consequences, you stay away from me, if there is any danger in waiting, you turn around and leave immediately, don't worry about me." ”

When Huayu heard me say this, where is he willing to do it, he hurriedly said: "No, if you want to die, everyone will die together, I believe that this must be the key to open this door, you can press it." ”

"Okay, when is it, you are still playing a child's temper with me, stand over there first, I will quickly evacuate when I press the switch, don't worry."

Huayu and I had several arguments, so they had to tell me in every possible way to be careful.

When the rain was far away, I turned my head to look at the black button lying in the black iron box.

This button can be said to have disturbed my mind, the already hot channel, at the moment plus I am a little nervous, my clothes have already been soaked with sweat.
