The spare battery of the walkie-talkie has been replaced, and the feeling of relaxation in everyone's hearts has disappeared at this moment.

The source of this signal does not bode well for them.

If the advance team of that little day back then was all folded in this hole, then where did this strange retreat signal come from?

After all, almost a century has passed since that war, and even if he was a child soldier at the beginning, he has now become an old man.

"I wonder if you've ever heard that story? There was once an anti-war devil soldier who was unwilling to fight, and after being conscripted to the front line, he became a deserter and hid in the deep mountains and old forests, and then lived alone in a cave, like a wild man, completely isolated from the world.

It wasn't until the fifties and sixties that he was found by our mountain patrol staff, and when he was dragged out of the cave, because no one had spoken to him for more than ten years, he had almost forgotten his native language, and could only pronounce hehehahaha.

I don't know what age it is, I don't remember my identity, but I can tell who he is by the outfit and weapons he left behind.

Later, after the negotiation of the embassy of the small day, this person was repatriated, but not long after he returned, this guy got into their mountains again, and he was never found again. ”

The story told by Qian Sheng, except for Lao Wei, basically did not cause any resonance among the others.

"I have the impression that Consultant Qian said this, it was still in the newspaper at that time, I remember very clearly, the devil was short, after the person was found, he changed into clean clothes, and it looked like a big monkey wearing human clothes, and my father used that newspaper to wrap me in twist flowers."

Wang Qiang took his words and said:

"According to what you mean, there are really people up there who are sending radio signals to summon spirits? That's just right, as long as I see it, I don't care about him, I will immediately correct the law on the spot, and we will settle the national enemies and personal grievances together. ”

"What do you think, this is just the guess of the third child."

As soon as the words fell, the compass pointer in Lin Yi's hand began to swing gently and disorderly.

This is obviously the receipt of interference signals from the outside world, which disturbs the magnetic field of the compass itself.

"Lao Wang, turn on the walkie-talkie!"

Before, they found that the sound of this frequency appeared once in a while, so in order to save power just now, the whole process was not turned on, Wang Qiang heard Lin Yi's arrangement, and immediately twisted the knob of the walkie-talkie.

There was a stabbing sound inside, and as the frequencies continued to contact, a sound came out again.

"Please drop all your equipment, turn around and return lightly, and assemble at the location of the large army!"

This time, everyone heard the sound clearly, and then another piece of Japanese came over the intercom.

The brothers stared at each other, and they were all numb.

My understanding of Japanese in this life is limited to a few keywords, and I don't have any of them here, so I don't know what it's talking about.

"The meaning of this passage is the same as the meaning of the sentence just now, let their men return lightly and come back to assemble with the large army."

Hearing this, everyone's nerves immediately tensed.

"Shouldn't these little devils have died back then? It's the same carrot essence we just met."

Speaking of Yu Wenrui, Xiao Liu was suddenly a little frightened in his heart.

"I'm afraid of an egg! It doesn't matter if he's a carrot or a white radish, he has to chop it for me today and feed it to the pigs. ”

Wang Qiang drew two toothed axes and walked back and forth, looking for a passage to go up.

"Don't worry, let me observe."

Lin Yi raised the fire fold and circled around.

Since Yuwen Rui was able to make another passage under Zhang Ji's hidden soldier cave, it means that he must have a very good understanding of the situation above.

Under this premise, he also had to ensure that the top would not collapse and affect his original route.

At critical moments, the upper floor can also be used as an escape route.

So, you're sure to find a connection in the vicinity.

"Here!"

Lin Yi found a hidden copper ring in the corner of the cave wall.

The copper ring is embedded in the wall, almost blending in with the color of the wall tiles, and if you don't look carefully, you really can't find such a thing.

"Guys try to stand against the wall, Lao Wang, give me another ladder."

Wang Qiang pulled open the hanging ladder and handed it over.

Lin Yi crossed the hanging ladder in front of him, coupled with body armor, which could basically protect the vital point, and reached out and pulled the copper ring violently.

There was actually a small hole in the wall that was more than half a person high.

After waiting for a while, nothing abnormal happened, he folded a glow stick and poked his head into it to observe.

Inside is a spiral staircase leading to the upper floor.

"There's a staircase leading to the upper floor, Lao Wang, you go up with me, the third and Lulu are guarding everyone."

At the scene, Lao Wei basically lost his mobility, and everyone else was also recovering from serious injuries, and Wu Jingshan's leg was inconvenient.

Qian Sheng and Bai Lu can count on it.

"Consultant Lin, I'll go with you!"

Jin Pengfei stepped forward and was rejected by Lin Yi.

"You are seriously injured and have not recovered, so it is better to rest here, take care of your master and everyone."

Wu Jingshan came to him with a 38 big cover.

"Advisor Lin, you pay attention to safety."

As he spoke, he stretched out his right hand to Lin Yi.

Seeing this, Wang Qiang hurriedly got into the low door, for fear of delaying the exchange of feelings between the two of them.

Lin Yimuran stretched out his hand.

A chill came from the palm of his hand.

Wu Jingshan actually quietly stuffed the matching gun into his hand.

This is a serious violation.

"You are"

"Stay safe!"

Wu Jingshan insisted on stuffing the gun into Ah 's hand, and turned to leave.

Lin Yi had no choice but to put away the gun first, and turned his head into the passage.

This spiraling staircase is relatively sloppy, the stairs are of different heights, and the whole process has to be bent on the waist, and it is quite difficult to climb.

Fortunately, the distance is not too long, and after waiting for the upper floor, I looked out through the ventilation holes in the wall.

It was still pitch black and nothing could be seen, but in the distance there was a red bright spot the size of a bean, flickering rhythmically.

Suddenly, there was a "click" in the passage.

The two of them immediately became alert.

Prick up your ears to listen, and after a burst of electricity characteristic of old-fashioned radios, the same voice they had heard on the walkie-talkie reappeared in the channel.

Wang Qiang frowned and looked at Lin Yi.

"How can I hear it not like it's coming from a human?"

Lin Yi stretched out his hand to cover his mouth and nose, and whispered:

"It's really not a human voice, it seems to be the movement of a steel tape recorder in the forties and fifties of the last century."

As early as the thirties of the last century, the United States invented the steel tape recorder, and since then it has replaced the gramophone as the mainstream entertainment facility in developed countries at that time, and with the outbreak of the Pacific War, it has flowed into East Asia.

Now it is certain that this voice is not made by a living person, but a new problem has arisen:

These devices need to be powered by electrical energy, and where does electricity come from? (End of chapter)
