The two hid at the entrance of the passage and waited quietly for a while.

The passage below was still pitch black, with no light at all, only the rhythmic flickering of the small red light beads.

The sound came from the speaker of the steel tape recorder, and after about a few seconds, the voice suddenly came out of the walkie-talkie on Wang Qiang's waist.

Scared both of them.

"What's that? Why didn't you turn this thing off? ”

"Forgot, forgot, mine, mine!"

Wang Qiang hurriedly turned off the volume knob of the walkie-talkie to the minimum.

The two of them calmed down for a moment, and looked out through the vent again, but there was still no superfluous movement around.

It stands to reason that if there is still one person in this passage who can breathe, they will definitely react to such a big movement just now.

The two of them waited quietly for about two or three minutes to make sure that there was nothing abnormal, and then carefully removed the cover of the passage and slowly slipped down the wall to the ground.

As soon as I stood firm under my feet, I only heard a "click".

It was as if something had been trampled on.

Lin Yi grinned and patted his chest gently.

"This one is mine, it's mine."

The two of them stood firm one after another, their backs pressed against the wall, so that their eyes could adjust to the surrounding environment as soon as possible, and then took out the fire fold from their arms, blew it, and took a circle around it.

It doesn't matter if you don't look at it, the place where they landed is actually piled up with a layer of dry bones.

The bones are charred black and filled with voids.

There are only two reasons for this condition, either due to poisoning or by an acidic substance.

"Lao Lin, look at this!"

Wang Qiang reached out and pulled out a steel helmet from the pile of dry bones.

"This thing looks like a devil's thing, and the standard should be a 90-style steel helmet."

With his understanding of military products, he should have guessed eight or nine.

The helmet's green livery has fallen off, leaving only a faded pentagram on it, and a few pieces of interlining known as the "Devil's Fart" in the hat.

"This five-pointed star was first bigger than this, and then this thing became the crosshairs we aimed at.

And this steel helmet is too thin, and it is panicked to wear it, so the devil soldiers put on this strip of cloth. ”

Wang Qiang threw down the steel helmet and pulled it around the ground a few times with his tooth axe.

He pulled out two handfuls of 38 large covers from the pile of dry bones.

From these things, it can be basically determined that this group of devil soldiers whose cause of death is unknown is the same group of people as the ghost soldiers they met before, who died in the trap and were washed up in the garbage heap.

"Why are all these people dead here?"

Lin Yi vigilantly raised the fire fold and took a few steps towards the position of the steel tape recorder, but found that there was a hole in the back.

"Lao Wang, come here."

Wang Qiang held up the fire fold and hurriedly moved closer to his position.

Lin Yi broke off two glow sticks and threw them into the depths of the passage.

The entire passage is in full view.

The ground was littered with dry bones, and judging by the number of skulls alone, at least a hundred people had died here.

Coupled with the corpses that died before, this devil unit, according to their establishment at that time, should be regarded as a squadron, with a number of about 150-200 people, which is larger than our company-level establishment.

Multiple bullet holes appeared in the walls, and there were even shrapnel from the explosion of a grenade.

"Damn, look at this situation, there was a fierce battle here at the beginning?"

Wang Qiang stretched out his hand and stroked the bullet marks on the wall and sighed.

At the end of this dry road was the American steel tape recorder they had just found.

It's a miracle that this thing is still working after all these years.

Lin Yi stepped forward and pointed the glow stick at the nameplate on the tape recorder.

"The place of origin is Chicago, it's sure it's the old beauty thing, the things made by the old United States back then were really awesome, and I was willing to give up the book, which is like now?"

Wang Qiang was thinking about it, and Lin Yi was studying the equipment around the wiring of these things.

Originally, this tape recorder had multiple knobs on it to control its operation.

The knobs on the tape recorder were removed and replaced with a piece of wire.

The wire is tied to a lever to form a linkage.

Its source of power is a power cord that goes deep into the ground.

Searching all the way down the power line, two slabs with gaps appeared on the ground.

Wires went through the slate.

The two of them worked together to pry open the stone slab and found two deep holes underneath, extending diagonally outward.

At the entrance of the cave, there is a square that looks like it has been around for some years, and the lines on it are connected to the outside world, as well as two meters.

It looks like a power generation and storage device.

"These devils have also made a lot of efforts, just this set of power generation and storage equipment was a treasure in the city back then.

You see, this line, leading to the outside, probably they chose the location early on and built a reservoir.

In the Tengger Desert, there are many areas of saline-alkali land, and they have built a permanent power generation and storage device through precipitation and natural salt, which has been running for so long that it can still be used normally. ”

Wang Qiang couldn't stop listening

"The devil is really willing to spend his blood, what is it that is worth their great effort?"

Lin Yi shook his head and continued to explore along the line.

Just underneath the steel tape recorder, a radio transmitter was found.

"Found it! Here's the roots! ”

Lin Yi exclaimed happily.

"This set of equipment in that year can really be regarded as the culmination of the world's science and technology core, through salt water power generation, battery storage, drive the steel tape recorder, the pre-recorded content is played, and then through this signal transmitter, the voice signal coverage of the full frequency band is released."

"That's why Lao Wei's walkie-talkie will appear on the stage, because he received the information sent here."

"That's right, but why didn't our walkie-talkie get the message?"

"Hey, don't you want to think about it, how many years has this thing been, the signal is intermittent, sometimes good and sometimes bad, whether you can receive it or not depends on fate, besides, we are standing here now, and we can hear it much more real than in the walkie-talkie."

Lin Yi nodded, and carefully looked at the set of equipment in front of him, still feeling a little unbelievable in his heart.

However, when his gaze shifted to the back of the device, his jaw dropped.

Just behind this set of equipment, a huge arc-shaped space appeared.

From the pickaxe marks and shovel marks on the walls, it can be seen that this place has been artificially excavated, and it should be that this group of devils expanded this place back then.

Now in this space, a military truck, several military sideways three-wheeled motorcycles, as well as mortars, machine guns, ammunition boxes and other things, is a small ammunition depot. (End of chapter)
