Fang Nian and Duan Rui glanced at each other, then Duan Rui walked over to check the wall, and after groping for a few times, he really found a white button hidden in the wall.

Duan Rui pressed it, and there was no special change on the wall, but he heard the sound of gears snapping.

"Kalalala......"

A moment later, the room shook a little, and then a white mist erupted from the corners of the room, and the doors and windows of the room closed in an instant.

"Oh no, fooled."

Fang Nian's sense of smell is very sensitive, this white mist is mixed with the smell of a large amount of ether, if the body is shrouded in fog, then Tie will definitely lose consciousness in an instant.

Thinking of this, Fang Nian wanted to turn around and arrest the officer again, and found that this guy was no longer there, and his figure had disappeared into the room.

Duan Rui didn't expect to be as shrewd as Fang Nian, and they all fell in love with this guy's way, and the two of them were really careless just now.

"What now, there's ether in this white mist."

In fact, Duan Rui didn't notice that she had begun to rely on the man in front of her unconsciously. Now after encountering something, he doesn't think of his own way like before, but asks Fang Nian as soon as possible.

Fang Nian didn't panic, but calmly glanced at the facilities in the house. The furnishings of the room are simple, except for the bed, only an old European desk remains.

The officer was not an immortal, it was impossible for him to disappear out of thin air, and he was stabbed three times in his leg by Fang Nian, and a lot of blood came out. But the bloodstains did not move, but only disappeared in place, so it is clear that the officer must have disappeared in this vicinity.

Thinking about it, Fang Nian began to squat on the ground and grope for a collapse, but after groping for a long time, he didn't find any special mechanism on this bed. At this time, the white mist had already filled half of the room, and Fang Nian and Duan Rui could only lean down and cover their mouths and noses with their clothes.

Fang Nian didn't find out, so he could only sit on the surface of the lin in the same sitting position as an officer. Then he began to rewind quickly, recalling every detail of the officer's activity just before his eyes.

Suddenly, Fang Nian was pleasantly surprised to find that this guy's right hand had indeed lightly knocked on the floor three times inadvertently by Fang Nian, and Fang Nian, who had insight skills, clearly recorded this in his brain.

Thinking of this, Fang Nian knelt on the ground, put his ears to the floor and listened carefully, his hands constantly tapping on the floor, as if looking for a hole under the floor.

And at this moment, when Fang Nian tapped on the third place, he found that the sound of tapping here would be much more hollow than before. It was obvious that there should be a mechanism under the floor, so Fang Nian tapped lightly a few times like an officer.

Sure enough, after a few crunching sounds, there was a click, and the bed board suddenly shook. Fang Nian observed the bed board and found that this was a copy, as long as a person drilled into the space under the bed along the copy, the copy would lock again.

Fang Nian was refreshed for a while, then stuck the futon and flipped it, and jumped down with a jump.

The space below was different from what Fang Nian had thought, he thought that what was hidden here was nothing more than a tunnel, but now it seemed that this place was far more than a tunnel, it should be a passage, high enough for an adult to stand alone.

At the same time, Fang Nian observed some distant situations, because the bricks and tiles in the tunnel were all mixed with silver powder. Therefore, although there are no lights, it is naturally bright.

Fang Nian and Duan Rui jumped into the tunnel, touched the bed board with their backhands, and the entrance closed.

The trap was well sealed, and the white mist was blocked, so they were safe for the time being.

The tunnel is high enough, but narrow, and it is extremely crowded for two people standing side by side in the tunnel.

Fang Nian didn't feel anything, he was just thinking about how to deal with the situation in front of him next.

But Duan Rui became a little restless at this time, this was the first time she had grown up and stayed in such a narrow space with a man.

Duan Rui bit her lip to hide her embarrassment at this moment.

"We ...... Shall we chase him? ”

Fang Nian came back to his senses at this time, and when he saw Duan Rui's appearance, he was embarrassed for a while.

"No need, I think we'll have a chance to meet, so don't rush it."

With that, Fang Nian squeezed past Duan Rui and walked in front.

"They should defeat those soldiers very quickly, and the troops will advance smoothly. We can't sit back and wait if we're stuck here, let's move forward first, there should be a way out of this tunnel. ”

"I'll go ahead, you follow me, pay attention to the situation in the back, there is likely to be a mechanism here."

finished, Fang Nian took the lead in walking forward, and Duan Rui hummed and obediently followed behind Fang Nian.

If Duan Rui's current appearance was for Jin Jinhui and them to see, they would probably drop their jaws in shock.

Walking along the passageway, they soon reached the exit, and when the two pushed open the hidden door and walked out, they were almost instantly stunned by what they saw.

It was a very large room, hundreds of meters long, and the height of the ceiling was more than 10 meters, which was as high as a 3 or 4-story building.

On the wall to the right of the room, there are countless hatches, like the cold storage doors of frozen corpses in a morgue, which is creepy.

Duan Rui looked at everything in front of him in surprise, and said incredulously.

"Is this really a train car? You can feel the shaking of the train, but it's illogical. ”

Fang Nian was also incomprehensible, indeed, from the time they came in to the present, there were many carriages they had passed by. However, it seems that the size and style of each carriage are different.

But when they looked out the window at the train, they found that it was actually a normal train, and there was no difference.

"Could it be a technique called space compression? I've seen descriptions of this technique in some ancient books. ”

Fang Nian had also heard it.

"Well, it's possible, it's hard to compress space in real society, but it may be possible to do it in the hunting ground. But that's all theoretical, and if your grandfather would, I don't think I would have taught you. ”

"Okay, let's not think about it, we are running out of time, and we have to find a way to move forward."

Duan Rui was indeed very interested in compressing space, but when he heard Fang Nian say this, he had no choice but to put it down first, after all, it was important to escape.

The two of them glanced at each other, and saw that the room number on the wall was 18, which made it clear that they had already crossed many carriages through the passageway.

And now they can't hear the sound outside at all, Ma Ming Luo Li They are still far away from themselves.

So it was imperative for the two of them to figure out what was hidden in this wall.
